Getting Started

LET’S TALK • Look at the pictures. Then answer the questions

A.

Stage 1.Giving reasons why something happened

Some students complete their classroom assignments on a personal computer. By making the lesson a game or enhancing it with sounds, graphics, and animation, computers make learning more enjoyable and increase retention.

2look ahead-erlangga

What do you think?

1. Do you know how to operate a computer?

2. How long have you studied with a computer?

3. What can computers do to help your work?

4. Do you know how a computer carries out instructions?

5. Do you agree with the above statement that says: “…. Computers make learning more enjoyable and increase retention”? Why/ why not?


ACTIVE LISTENING • Read and listen to a text about a pipeline and pay attention to the intonation. Circle the right action verbs used in the text. Then, fill in the table.

B.


Have you ever heard about a pipeline in computer technology? Guess what. Right. A pipeline is very

close to a computer. But can you tell me what a pipeline is? Well, let me explain. A pipeline in a computer is a sequence of stages a computer (1.uses, chooses, processes) to carry out instructions.

The CPU makes sure every stage in a pipeline is always (2. doing, working, operating) on an instruction. As a stage of pipeline in the CPU (3. finishes, separates, deletes) manipulating an instruction, it (4. keeps, hands, works) its instruction to the next stage and gets another instruction from the stage before it, (5. running, moving, stopping) several


instructions along the pipeline simultaneously. This process is more efficient than it would be if it instruction had to start at the first stage after the previous instruction finished the final stage.

Oh, I almost forgot, the more pipelines a CPU has, the faster it can (6. execute, cut, link) instructions. A CPU with two or more pipelines is said to be super pipelined or superscalar. Okay. Have you got it? Not yet. How about (7. going, visiting, playing) to the library and (8. searching, discovering, finding) more explanations about a pipeline? See you and good luck.

Human Respiratory System


The second phase of respiration begins with the movement of carbon dioxide from the cells to the bloodstream. The bloodstream carries carbon dioxide t o the heart, which pumps the carbon dioxide-laden blood to the lungs.

……..

The first phase of begins with breathing in or inhalation. This inhalation brings air fro out side the body into the lungs. Oxygen in the air moves from the lung through blood vessels to the heart, which pumps the oxygen-rich blood to all parts of the body. Oxygen then moves from the blood stream into cells, which completes the first phase of respiration. In the cells, oxygen is used in a separate energy producing-process called cellular respiration., which produces carbon dioxide as a byproduct.

……..

Do you know what helps your body get oxygen from the air? Right. it’s the respiratory system. Can you tell me the most important organs in the respiratory system? Yes, your nose, mouth, trachea, lungs, and diaphragm.

……..

In the lungs, Breathing out or exhalation removes carbon dioxide from the body, thus completing the respiration cycle. Do you understand so far? (the bell rings) Well, sorry. I guess time is up for today. So see you tomorrow. Bye

……..

The respiratory system, in anatomy and physiology, are organs that deliver oxygen to the circulatory system for transport to all the body cells. The respiratory and circulatory systems work together to deliver oxygen to cells and remove carbon dioxide in a two-phase process called respiration.

……..


Find out:1. Why are these organs (nose, lungs, trachea, mouth,

bronchial tube, diaphragm) really essential for us?

2. Do you know what would happen if those organs are not working properly?

Life Cycle of the Malaria Parasite


Malaria is (1. infectious-an-disease) caused by (2. parasite-one-celled-a) known as Plasmodium. The parasite is transmitted to humans by (3. the-the-of-bite-Anopheles-mosquito-female). (4. plasmodium-The-parasite) spends (5. cycle-life-its) partly in humans and partly in mosquitoes.

(A) Mosquito infected with the malaria parasite bites human, passing cells called sporozoites into (6. bloodstream-human’s-the).

(B) Sporozoites travel to the liver. Each sporozoite undergoes sexual reproduction, in which its nucleus splits to form (7. new-two-cells), called

(C) Merozoites enter the bloodstream and infect (8. red-cells-blood).

(D) In (9. cells-red-blood), merozoites grow and divide to produce more merozoites, eventually causing the red blood cells to repture. Some of the newly released merozoites go on to infect other ( 10. red-cells-blood)).

(E) Some merozoites develop into (11. cells-sex) known as male and female gametocytes.

(F) Another mosquito bites (12. human-the-infected), ingesting the gametocytes.

(G) In (13. the-stomach-mosquito’s), the gametocytes mature. Male and female gametocytes undergo sexual reproduction, uniting to form a zygote.


The zygote multiplies to form sporozoites, which travel to (14. salivary-glands- the-mosquito’s).

(H) If this mosquito bites another human, the cycle brgins again.
