III. Now read the text and then answer the questions given after it.

Look at the picture. There are some instru­ments for the car panel there. In fig.l the speedometer is indicating zero kph /kilometers per hour/. The car is not moving. The engine is turning at minimum speed (approximately 750 rpm /revolutions per minute/).

As the engine is turning slowly the alter­nator is also turning slowly. It is not pro­ducing enough current for the engine. The battery is discharging and so the ammeter is indicating about -5A /ampere/.

Look at fig.2. The car is now moving at 60 kph. The engine is turning at 2500 rpm and so the alternator is turning quite fast. It is producing a strong current for the engine. The battery is now recharging from the alternator and so the ammeter is indicating +10A.

 

1. Is the speedometer indicating zero kph in fig. 1?

2. The car is not moving in fig.l, is it?

3. Why is the alternator turning slowly?

4. Is the battery charging or discharging in fig.l?

5. What is the car doing in fig.2?

6. The engine is turning at 2300 rpm now, isn't it?

7. Is the alternator producing a strong or a weak current for the engine in fig.2?

8. Is the battery recharging now?

 

IV. Complete the sentences using the wordlist below.

Look at fig.3. The car … now moving … 90 … . The engine is … at the speed of 4500 rpm. However, the alternator … not producing any …. The ammeter … … -20 A. In other words, the battery is … rapidly, … the engine is … at a high speed. Therefore, the … is not produc­ing … power.

is, at, kph, current, turning, is, alternator, although, any, turning, is, indicating, discharging.

 

V. You are driving a car now. Your friend is sitting next to you. He does not know anything about the car devices. Describe him the work of a tachometer, a speedometer or an ammeter.

Activity

I. Look at the pictures below. Discuss with your fellow student what you see in the picture.

EXAMPLE:

A: Who is that man in the picture?

B: Oh, it's Mr. Kosov.

A: Is he repairing his car?

B: No, he isn't.

A: He is painting his car, isn't he?

B: No, you are wrong.

A: What is he doing there?

B: He is cleaning his car.

A: I see. Is he cleaning it in the garage or in the workshop?

B: In the garage, of course.

 

a) Mr. Morton is in the car

to drive a car

to press the pedal

to look at the indications of car

instruments to watch indications of a tachometer and an ammeter

 

b) Children are in the classroom

to make mathematical operations

to solve different problems

to draw different shapes and measure their areas

to measure in cm² or in in²

 

II. Your friend is showing you how to draw a graph. Describe what he is doing step by step. Begin with the words:

First, he is drawing …	Next…
Then …	After that …
