Chapter 8खीर की दावत

इस कविता में सभी जीवो और मनुष्यों केबीच के परस्पर प्रेम को दर्शाया गया है। इस कविता में एक बिल्ली है, जिसका नाम लाली है। उसे दूध और दही बहुत पसंद है और वह कटोरी भर कर सब चट कर जाती है।एक दिन माँने खीर पकाई थी। जब लाली को उसकी खुशबू आई तो वह दबे पांव आकर सारे खीर को चट कर गई, सब खा गई।जबवह खीर खाकर जाने लगी तब मां की नजर उस पर पड़ी और माँने जब उसको गुस्से से देखा तो लाली डरकर कांपने लगी और बोलने लगी कि मैंने तो आपसे पूछा था मैं आऊं मैं आऊं करके पर आपने तो तभी मुझे रोका नहीं, तो फिर उसने माँ से माफी मांग ली और बोली कि मैं हमेशा पूछ कर ही आऊंगी।

Chapter 1 चलमरदानेकविता

इस कविता के द्वारा कवि हमें यह बताना चाहते हैं कि हमें अपने जीवन को स्वाभिमान के साथ जीना चाहिए। निडर व्यक्ति ही अपने मंजिल तक पहुंचते हैं, और जीवन उसी का है जो मुश्किलों से नहीं घबराता।

इस कविता में कवि कह रहे हैं कि सभी बहादुर भारतवासियों अपना सीना ताने चलिए ,हाथ हिलाते ,पाँव बढ़ाते, मुस्काते गीत गाते चलिए

हमारा देश, हमारा वेश हमारी जाति, हमारा मुकाम सब एक है हम किसी से डरे हुए नहीं हैं।

कवि कह रहे हैं कि हमारा भारत अमर है, उनकी सागर की लहरें अनोखी है, गंगा जमुना का पानी पवित्र है हमारे पर्वतों ने अपने सिर को ऊंचा उठाए रखा है वह सबके लिए प्रेरक, रक्षक और दोस्त के समान है। और कवि यह संदेश देना चाहते हैं कि जो इस संसार के पथ पर ना रुकेगा, ना झुकेगा और ना ही मुड़ेगा उसी की जीत होगी। जो किसी परेशानी से नहीं डरेगा वही जीत पाएगा इसीलिए हमे शा हंसते- मुस्कुराते गीत गाते रहना चाहिए और चुनौतियों से कभी डरना नहीं चाहिए।

Ch – Plant Reproduction

Dispersal of seeds:

As we know that plants cannot move from one place to another. If all seeds fall and germinate near the parent plant, they will not get enough sunlight, air, water and minerals from the soil to grow, also many seedlings will not survive. The process of scattering of seeds or fruit away from the parent plant is called dispersal. Seeds get dispersed from the parent plant to far-off places by wind, water, animals or explosion (bursting open) of fruits. Therefore they are called agents of dispersal.

Questions & answers

5. Define dispersal. List the various ways in which seeds get dispersed.

Ans. The process of scattering of seeds or fruits away from the parent plant is known as dispersal.

What is Highest common Factor (H.C.F.) ?

Ans: H.C.F. stands for highest common factor, and the H.C.F. of two or more given numbers is the greatest number that completely divides each of the given numbers.

Example :

Factor of 12 = 1, 2,3,4,6,12 and Factor of 18 = 1,2,3,6,9 and 18.

From the above result, we find the highest common factor =6

By the number 6 , both the numbers 12 and 18 completely divide.

Therefore, H.C.F. of 12 and 18 =6

There are three methods of finding H.C.F.

(i)Common Factor Method

(ii)Prime Factor Method

(iii)Division Method.

What is Lowest Common Multilpe(L.C.M.) ?

Ans : L.C.M. stands for Lowest Common Multiple. The L.C.M. of two or more given numbers is the lowest (smallest) number that is a multiple of each of the given numbers.Thus, it is the smallest number which is exactly divisible by each of the given numbers.

Example :

Multiple of 5 = 5, 10,15, 20, 25, 30, 35, 40, 45....

Multiple of 15 = 15, 30, 45, 60....

Therefore, Common multiples of 5 and 15 = 15,30,45....

Therefore, L.owest common multiple of 5 and 15 =15

Therefore, L.C.M. of 5 and 15 = 15

There are three methods of finding L.C.M.

(i)Common Multiple method

(ii)Prime Factor method

(iii)Common Division method.

১৭৭২ খ্রিস্টাব্দের২২শেমে রামমোহন রায় জন্মগ্রহণ করেন। তাঁর পিতার নাম ছিলরামকান্ত রায় মাতা হলেন তারিণী দেবী ।

তিনি বাল্যকালে রাধানগর গ্রামে সংস্কৃত আরবি-ফারসি প্রাথমিক শিক্ষা লাভ করেন ।কিশোর বয়সে তিনি পাটনায় গিয়ে আরবি ও ফারসি ভাষা ভালোভাবে শেখেন। তারপর কাশিতে গিয়ে তিনি সংস্কৃত ভাষা ও বেদান্ত শাস্ত্র চর্চা করেন। রামমোহন রায় মাত্র ২৩ বছর বয়সে উর্দু এবং ইংরেজি ভাষায় ব্যুৎপত্তি লাভ করেন।

মাত্র ১৬ বছর বয়সে রামমোহনের ধর্ম বিষয়ে মতবিরোধ হয়। পৌত্তলিকতার বিরোধী হওয়ায় তিনি বাড়ি ছেড়ে চলে যান। রামমোহন রায়ের কর্মজীবন ছিল বহুমুখী। সমাজসংস্কার, শিক্ষাসংস্কার, ধর্মসংস্কার, গ্রন্থ রচনা ও সাময়িকপত্র পরিচালনা প্রভৃতি তাঁর প্রধান কর্মধারা।

সমাজেরকুপ্রথাগুলিকেদূর করার জন্য রামমোহন সচেষ্ট হন । তারসময়ে মৃত স্বামীর চিতায় সহমরণ প্রথাপ্রচলিত ছিল।তিনিআন্দোলন করে গভর্নর জেনারেল লর্ড বেন্টিং এর সহায়তায় আইনের মাধ্যমে সতীদাহ প্রথা রদ করেন। তিনি বেদান্তের ওপর ভিত্তি করে আত্মীয় সভা স্থাপন করেছিলেন ।এই আত্মীয় সভা ছিল ব্রাহ্ম সমাজের ভিত্তি , এইব্রাম্ভসমাজইপরেব্রাহ্ম ধর্ম প্রচারে উদ্যোগী হয়। দিল্লির বাদশাহ দ্বিতীয় আকবর সাহেব বিশেষ প্রতিনিধি হয়ে রামমোহন রায় লন্ডন গিয়েছিলেন। বাদশাহ তাকে দিয়েছিলেন রাজা উপাধি।১৮৩৩ খ্রিষ্টাব্দের ২৭ সেপ্টেম্বর তিনি শেষ নিঃশ্বাস ত্যাগ করেন।আধুনিক ভারতবর্ষের উন্নয়নের মূলে ছিলেন রামমোহন রায়ের প্রেরণা। এইজন্য রবীন্দ্রনাথ তাকে আখ্যা দিয়েছিলেন ভারত পথিক।

BIOLOGY

Chapter:4: Photosynthesis and Respiration

Today we will discuss about how does photosynthesis occur, end products their utilization and importance of photosynthesis.

Q5. What is photolysis?

· After absorbing sunlight chlorophyll get excited and splits the water molecules into hydrogen and hydroxyl ions. This process is known as photolysis.

Q6. What are the end products of photosynthesis and write their utilization also.

i) Glucose: utilized by plants for growth and energy. Extra glucose is converted into starch and sucrose and stored.

ii) Oxygen: major part is released in the atmosphere through stomata. Some part is utilized by plants for its respiration.

iii) Water: reutilized by plants for photosynthesis.

Q7. Name the factors affecting photosynthesis

i) Light: Photosynthesis increases with increase in light but up to a certain limit.

ii) Availability of CO2 and water: Up to a certain limit concentration of CO2 increases photosynthesis.

When enough water is not present, the rate of photosynthesis decreases.

iii) Temperature: Optimum temperature for photosynthesis is between 200 C and 350 C.

Q7. Write importance of photosynthesis.

i) Provide food for all living organizations either directly or indirectly.

ii) By product oxygen is utilized for all living organisms for respiration.

iii) During this process, a balance between O2 and CO2 is maintained in the atmosphere.

Physics (vii)

Motion

What is oscillatory motion?

Ans: When an object as a whole moves to-and-fro about its mean position, it is said to be in oscillatory motion.

What is mean position?

Ans: Mean position is the position when the object is at rest.

Example of oscillatory motion: A swing in motion and a swinging pendulum of a wall clock.

What is vibratory motion?

Ans: If the whole body does not move to-and-fro as a single unit, but some of its parts oscillate about their mean position, it is known as vibratory motion.

Note: Vibratory motion is an effect of oscillatory motion of some parts of an object. Thus, vibratory motion is a special case of oscillatory motion.

Example of vibratory motion :

(i)The motion of strings of a guitar when plucked.

(ii)The motion of the prongs of a tuning fork when hit.

What is Repetitive motion?

Ans: When an object moves such that it repeats its motion after a certain interval of time, it is said to be in repetitive motion.

There are two types of repetitive motion.

(i)Periodic motion and (ii) Non-periodic motion

What is Periodic motion?

Ans: The motion that repeats itself after regular intervals of time is called periodic motion.

Example: (i)The revelation of the earth around the Sun.

(ii)The motion of the pendulum of a wall clock.

What is non-periodic motion?

Ans: The motion that repeats itself but not after regular intervals of time is called non-periodic motion.

Example: (i) swaying of branches of a tree.

(ii)Motion of our lungs during breathing.

(iii)Swinging of our arms and legs while walking.

What is Random motion?

Ans: An object moving with no specific path and frequently changing its direction (and/ or speed) is said to be in a random motion.

Example :(i) A dancing girl who moves in different directions at different speeds.

(ii) A football player moves in different directions during a game of football.

What is combination or multiple motions?

Ans: When an object possesses two or more types of motions at the same time, it is said to have a combination motion or multiple motion.

Example: The earth rotates about its axis (Rotatory motion) in a fixed time interval (periodic motion) and at the same time it revolves around the Sun in a curved path (curvilinear motion) in a fixed time interval (periodic motion).

Literature

The west wind-

John Mansfield.

In the poem 'The West Wind' by John Masefield, the poet starts by describing, with very poetic imagery of birds, how the west wind is different from other winds 'it's a warm wind, full of birds' cries.' There is a touch of melancholy, perhaps home-sickness as he describes how it brings tears too, and memories from an old land. He goes on to describe the restful, pastoral beauty of the land where even the dead can lie in the green. He then brings in voices, perhaps of family and friends, calling him home as he is missing April's beauty. The voices then tempt him some more with idyllic images from home (white blossom, young green corn, running rabbits, warm sun.) The voices seem to presume that the poet's heart is sorrowful, bruised and sore. The end of the poem sees the poet appear to make a decision. he will go home as he has decided that is where he truly belongs.

Answer the following questions.

4. How do we know that the poet is from the west? pick out the lines or phrases in the poem which tells us this.

We come to know that the poet is from the west with the help of the line “ ln the find land, the west land, the land where I belong”

As well as when the west wind addresses him as brother and ask him, “will ye not come home to us again”?

5. What conclusion does the poet reach in the end?

The poet finally makes a resolute decision to return home Westward and tread on the White Road, the cool and green grass where he can rest his head and heart. The fine land, that is filled with violets, warm hearts and thrushes song, the west land where he truly belongs.

2.सेठ ने यादों पातं सारी कथा सुनाई सुनकर सेठानी की वेद ना जाने कहां विलीन हो गई।

क) आद्योपांत से क्या तात्पर्य है कौन सी कथा आद्दोपांत सुनाई?

ख)यह कथा सुनकर सेठानी पर क्या प्रभाव पड़ा ?

ग) दीया जलाते समय क्या घटना घटी ?

घ) सेठ सेठानी नीचे तक खाने में उतरे तो क्या देखा ?

उत्तर

1) आदयोपांत से तात्पर्य है प्रारंभ से अंत तक। सेठ जी ने सेठानी को कुंडलपुर के सेठ के पास जाने और उनसे और उनकी पत्नी से क्या वार्तालाप हुई यह सब सुना दिया।फिर निराश होकर वही धर्मशाला में रात काटकर अगले दिन शाम तक अपने घर आ गए।

2) या कथा सुन कर सेठानी की सारी वेद ना जाने कहां विलीन हो गई। उनका ह्रदय यह जानकर उल्लास इट हो उठा कि विपत्ति में भी सेट जी ने धर्म नहीं छोडा। धन है मेरे पति सेठ जी की चरणों की रंज माथे पर लगाते हुए गोली की भगवान सब भला करेंगे।

3) रात का अंधकार फैलता जा रहा था सेठानी उठ कर दिया जलाने के लिए दान में आई तो रास्ते में किसी चीज से ठोकर लगी।समर कर दिया जला कर नीचे की ओर देखा कि दिल्ली के सहारे एक पत्थर ऊंचा हो गया और जिसके भी जो भी एक लोहे का कुंडा लगा है।

4) सेठ और सेठानी ने उस पत्थर को कुंडा पकड़कर उठाया तो नीचे सीढ़ियां बनी हुई थी। दोनों सिढियो से उतरकर नीचे गए तो देखा कि तह खाने में जवाहरात जगमग आ रहे हैं।उनके आश्चर्य का ठिकाना नहीं रहा दैव लीला ने उनके हृदय को उल्लास से भर दिया ।

3. देवकी इस माया का रहस्य उनकी समझ में नहीं आया दोनों निशब्द खड़े थे ।

क) यह दोनों कौन थे ? किस माया का रहस्य उनकी समझ में नहीं आया?

ख) किस वाणी को सुनकर कृत कृत्य हुए.? फिर उन्होंने क्या किया

ग) वह दिव्य वाणी क्या थी ?

घ) क्या यह उनके आदर्श और धर्म परायणता का फल था ?

उत्तर

1) यह दोनो सेट और सेठानी थे जब वे दोनोंतहखाने की सीढियोंसे नीचे उतर कर पहुंचे तो यह देखकर वह दंग रह गए कि तहखाना जवाहरात से जगमग आ रहा है इस माया का रहस्य उनकी समझ में नहीं आया कि आखिर ऐसा हुआ कैसे ?

2) तह खाने में से आती हुई अदृश्य दिव्य वाणी को सुनकर से साथ सेठानी दोनो कृत कृत हुए उन्होंने वह धरती पर माथा टेक कर भगवान के चरणों को प्रणाम किया ।

3) तहखानेमैं जवाहर रातों को देखकर वे दोनों निशब्द खड़े रहेंगे कि इस माया का रहस्य उनकी समझ में नहीं आया तभी अदृश्य पर स्पष्ट स्वर में सुनाई दिया,आओ सेठ! स्वयं भूखे रह कर अपना कर्तव्य मानकर प्रसन्नचित मन से तुमने मरण आसन कुत्ते को चारो रोटियां खिलाकर उन की जान बचाई उस महायज्ञ का यह पुरुस्कार है।

4) सेठ ने बहुत से यज्ञकिए और दान में ना जाने कितना धन दिन दुखियों में बात दिया था उनकी धर्म परायणता का ही यह फल था कि उन्हें अपने तह खाने में दबी हुई धन अनायास ही मिल गई और वे गरीब से फिर से धनी हो गए।

-Chemical Equation

-Significance of Chemical Equation

-Limitations and drawbacks of Chemical Equation

1) Chemical Equation:-

A Chemical Equation is a brief representation of a chemical change in terms of symbols and formulae.

· The substance which reacts among themselves to bring about the chemical change is termed as “Reactants”.

· The substances which are produced as a result of the chemical change is termed as “Products”.

2) Principles involved in writing Chemical Equation:-

a) A chemical equation must represent a true chemical change.

b) The reactants are always placed on the left hand side.

c) The formulae of various reactants and products are separated by a plus (+) sign.

d) The reactants and the products are separated by a arrow (→) pointing towards the products or the sign of equality(=) which means to produce.

e) It should be balanced i. e. the total no. of atom of each kind on the both sides of the arrow must be equal.

For Example:-

3) Significance:-

A chemical reaction reveals –

i. The nature of the reactants and products.

ii. The number of molecules ( or moles ) of the reactants and the products.

iii. The relative number of moles of reactants and products.

iv. The weight of the substances entering into the reaction and those of the product formed.

v. The volumes of the reacting gases.

For example:-

Zn + 2HCl → ZnCl2 + Cl2

65g 2(1+35.5)g (65+2x35.5)g 2g

=73 g =136 g

1 ) Qualitatively :-

It tells that Zinc reacts with Hydrogen chloride to produce 1 molecule of Zinc chloride and 1 molecule of Hydrogen.

2) Quantitatively:-

1 atom of Zn reacts with 2 molecules of HCl to produce 1 molecule of ZnCl2 and 1 molecule of H2.

Q. What are the limitations of Chemical Equation and how to solve this ?

A.

1) The physical state of the reactants and products:-

A chemical eq. doesn’t tell whether the reactants and products are solids, liquids, gases or in the form of solution.

· It’s removal :-

This limitation can be removed by putting thedifferent types of subscripts beside the symbol of reactants and products.

(s) for solid

(l) for liquid

(g) for gases

(aq) for aqueous solution

e. g. –

MgCO3 (s)+ H2SO4(aq) → MgSO4(aq) + CO2(g) + H2O(l)

2)Concentration of the reactants or the products when present in the form of solution is not known:-

This limitation can’t be fully removed. However, ‘dil’ can be used for dilute solution and ‘conc.’ can be used for concentrated solutions.

3)The conditions necessary for the reaction to occur:-

The reaction does not tell anything about the conditions such as temperature, pressure, catalyst etc which is necessary for the chemical change.

· It is removed by mentioning the conditions of the reaction on the arrow-head.

e. g. –

4)Heat change:-

The reaction does not tell anything about the heat energy evoled oe absorb during a chemical reaction.

· It can be removed by writing “Q KJ” on the products side.

· “- QJ” is written if the heat is absorbed.

· “+QJ” is written if the heat is evolved.

e. g.-

C(s) + O2 (g) → CO2 (g) + 393.5 KJ

( when heat is evolved)

N2 (g) + O2 (g)→ 2NO(g) + 2NO (g) – 180 KJ

(when heat is absorbed)

5)Precipitation or Evaluation of a gas:-

A reaction does not tell whether an insoluble compound gets precipitated or a gas is evolved during a chemcical reaction.

· It is removed by using a downward arrow(↓) for the precipitated compound and a upward arrow(↑) for a gas evolved.

e. g. –

NaCl(aq)+AgNO3(aq)→AgCl(s)↓+NaNO3(aq)

CaCO3(s)+dil.2HCl(aq)→ CaCl2(aq)+H2O(l)+

CO2(g)↑

6) Reversibility of the reaction:-

A reaction does not tell whether the reaction is reversible or not.

· This drawbacks is removed by using an arrow in the backward direction(←) in addition with forward reaction arrow(→).

e. g. –

Geography

Structure of the Earth

At a glance:

Our planet Earth is more than 5,000 million years oldand is still in the process of changing: In one year the Atlantic Ocean widens by 10 cm whilethe Pacific Ocean is shrinking as the continents moveslowly across the globe.The Red Sea is in 'its infancy'. In 60 million years timeit will be as wide as the Atlantic Ocean. Africa andAsia may split apart as a result of the Mediterraneanmerging with the Atlantic Ocean.

Layers of the Earth:

The Earth comprises three main realms or regions –

· TheLithosphere which is the solid, inorganic section,

· TheHydrosphere which is the liquid section and

· The Atmosphere or gaseous section.

The thin outermost layer, the Earth's crust, averagesabout 17 km in thickness throughout and is referredto as the mineral skin. It is made up of the continentsand oceansand from it emanates the soil, sedimentsalt, gases, liquid and all components of the Earth inits widest connotation.

The composite zone inhabited by most living creaturesis called Biosphere. It includes a part of the atmosphere,the hydrosphere and a part of the lithosphere.The temperature within the Earth increases withdepth at the rate of 1°C for every 32 m depth,living an average temperature of 5000°C at thecentre of the Earth.

The Earth consists of three major concentric layers– these are called:

· The Crust or Lithosphere,

· The Mantle or Mesosphere and

· The Core or Barysphere.

Original Text

Paraphrase

[Venice – A street]

[Venice – A street]

Enter Salerio and Solanio.

Enter Salerio and Solanio.

SALERIO:

Why, man, I saw Bassanio under sail;With him is Gratiano gone along;And in their ship, I am sure, Lorenzo is not.

SALERIO:

I saw Bassanio sail away, and Gratiano went with him. I’m sure Lorenzo isn’t on their ship.

SOLANIO:

The villain Jew with outcries rais'd the duke;Who went with him to search Bassanio's ship. (5)

SOLANIO:

That wicked Jew got the duke to listen to his complaints. The duke went with him to search Bassanio’s ship.

SALERIO:

He came too late, the ship was under sail:But there the duke was given to understand,That in a gondola were seen togetherLorenzo and his amorous Jessica;Besides, Antonio certified the duke, (10)They were not with Bassanio in his ship.

SALERIO:

He got there too late. The ship was already sailing. But once he got there, the duke learned that Lorenzo and his lover Jessica were together in a gondola. In any case, Antonio assured the duke they weren’t with Bassanio on his ship.

SOLANIO:

I never heard a passion so confus'd,So strange, outrageous, and so variable,As the dog Jew did utter in the streets:My daughter!—O my ducats!—O my daughter! (15)Fled with a Christian?—O my Christian ducats!—Justice! the law! my ducats, and my daughter!A sealed bag, two sealed bags of ducats,Of double ducats, stolen from me by my daughter!And jewels; two stones, two rich and precious stones, (20) Stolen by my daughter!—Justice! find the girl!She hath the stones upon her, and the ducats!

SOLANIO:

I’ve never heard such confused emotions as what that Jew dog was shouting in the streets. “My daughter, oh my ducats, oh my daughter! Ran off with a Christian! Oh my Christian ducats! Justice, the law, my ducats, and my daughter, a sealed bag, two sealed bags of ducats, of double ducats, stolen from me by my daughter, and jewels—two stones, two rich and precious stones—stolen by my daughter! Justice, find the girl! She has the stones on her, and the ducats.”

SALERIO:

Why, all the boys in Venice follow himCrying,—‘His stones, his daughter, and his ducats.’

SALERIO:

I know, all the boys in Venice are following him, yelling, “His stones, his daughter, and his ducats!”

SOLANIO:

Let good Antonio look he keep his day, (25)Or he shall pay for this.

SOLANIO:

I hope Antonio repays his loan on time, or he’ll suffer for this.

SALERIO:

Marry, well remember'd:I reason'd with a Frenchman yesterday,Who told me, in the narrow seas that partThe French and English, there miscarried A vessel of our country, richly fraught: (30)I thought upon Antonio when he told me,And wish'd in silence that it were not his.

SALERIO:

That’s a good point. I spoke with a Frenchman yesterday who said that a Venetian ship loaded with treasure was wrecked in the English Channel. I thought about Antonio when he told me. I silently hoped it wasn’t his ship.

SOLANIO:

You were best to tell Antonio what you hear;Yet do not suddenly, for it may grieve him.

SOLANIO:

You should tell Antonio what you hear—but don’t do it suddenly, because it might upset him.

SALERIO:

A kinder gentleman treads not the earth. (35)I saw Bassanio and Antonio part:Bassanio told him, he would make some speedOf his return; he answer'd, “Do not so,Slubber not business for my sake, Bassanio, But stay the very riping of the time; (40)And for the Jew's bond, which he hath of me,Let it not enter in your mind of love:Be merry; and employ your chiefest thoughtsTo courtship, and such fair ostents of love, As shall conveniently become you there:” (45)And even there, his eye being big with tears,Turning his face, he put his hand behind him,And, with affection wondrous sensible,He wrung Bassanio's hand, and so they parted.

SALERIO:

There’s no nicer guy in the whole world. I saw Bassanio and Antonio say goodbye. Bassanio told him he’d try to hurry back. Antonio answered “Don’t rush. Don’t do a sloppy job for my sake, Bassanio. Stay until everything is finished. As for the Jew’s contract, don’t let it be a factor in your plans. Be happy and concentrate your thoughts on love and how to win your love.” Then his eyes started tearing up. He turned his face away. Then he shook Bassanio’s hand affectionately—and they separated.

SOLANIO:

I think he only loves the world for him. (50) I pray thee, let us go and find him out,And quicken his embraced heaviness,With some delight or other.

SOLANIO:

I think he only loves life because of Bassanio. Let’s go find him and cheer him up.

SALERIO:

Do we so. (55)

SALERIO:

Yes, let’s do that.

[Students should read the original play and also the paraphrase given in the school prescribed textbook]

Summary

· Bassanio tells Portia that he too had presented the ring to the lawyer who saved the life of Antonio. Portia is not ready to believe Bassanio’s words and she too fears like Nerissa that Bassanio must have presented the ring to some young woman.

· Portia, feigning anger, then tells Bassanio that had he understood the worthiness of the person who gave him the ring (i.e. Portia) he would have, under no circumstances, parted with the ring. She tells him that she is sure that he gave the ring to some woman.

· Bassanio tries, without success, to convince her that he gave it to a civil doctor, a man.

· Portia threatened Bassanio that if the doctor ever came to their house, she will not deny him anything. Nerissa maintains the same tune and tells Gratiano that she shall be doing the same for the doctor’s clerk.

· On seeing that Portia and Bassanio, Nerissa and Gratiano have started quarrelling, Antonio says that he is unfortunately responsible for all these quarrels. Portia tells him that he should not feel perturbed on that account and he is perfectly welcome at her house

· Bassanio then begs pardon of Portia and assures her that never afterwards in his life will he commit the same mistake again.
