What can we do with computers?
We can use computers to calculate.
They can calculate at a faster speed
than we can and almost never give
wrong answers. We can also type and
draw things with them. In addition,
computers can do important jobs like
operating railways and flying planes
and spaceships.
Is a computer cleverer than me?
The answer is “No”. Your brain can produce new
ideas but computers cannot. However, one day
computers may be able to do a better job than
human beings. For example, they may be better
than doctors at doing their job.
What will happen to us if computers can do all our
jobs? Will we have nothing to do? Computers may change our lives, but will they make them better?
1 If something is very small, it is _____________. (line 5)
Some young people always need help from their parents. They should learn to _____________ themselves. (line 8)

do maths. It was used in ancient
China, Rome, Egypt and Greece.
Today some people still use the
abacus.

C4095
Complete this email using information from the table and the key words.
The C4095 weighs 4 kg, so it is lighter than the C4091. The C4095 costs 1,298 yuan, so it is a little more expensive than the C4091. We have sold 50 C4095 monitors and 38 C4091 monitors this month, so the C4095 is more popular than the C4091.

The C4091 is cheaper than the C4095. It also has a clearer picture than the C4095.

Underline the words in the paragraph that are stressed.
? Stress nouns, verbs, adjectives, adverbs and numbers.
? Do not stress words like a, the, is and have except for
special reasons.
We already know two rules about sentence stress:
Salesman: Can I help you, sir?
Allen: Yes, I need a monitor. How much is the C4095?
Salesman: It costs ￥1,298, and it’s our newest model.
Allen: What about its weight?
Salesman: It’s light and only weighs 4kg.
Allen: Does it sell well?
Salesman: Yes, it is the most popular model in our shop. We
have sold 50 this month.
Put two underlines under the words that we might give extra stress to in the conversation below. Think of a reason why we might give these words extra stress.
These words contain very important information to the speakers.
? Give extra stress to the most important word in the sentence. You, the speaker, must decide what the most important word is.
Here is the third rule:
John borrowed a book from the school library
yesterday afternoon.
Think about what information Tony wants to know and give extra stress to the words in your answers.
John borrowed a book from the school library
yesterday afternoon.
Tony:
Who borrowed a book from the school library yesterday afternoon?
What did John do yesterday afternoon?
What did John borrow from the school library yesterday afternoon?
Where did John borrow a book yesterday afternoon?
When did John borrow a book from the school library?
A1 Read the conversation below and practise it in pairs. Give extra stress to the words underlined twice.
Frank: Which kind of computers are better, desktops or laptops?
Amy: Laptops, I think.
Frank: Why?
Amy: Laptops are lighter. They’re easier to carry around than
desktops!
Frank: Yes, but desktops are often cheaper than laptops. And I
don’t really have much money.
Amy: Well, then a desktop is probably a better choice for you.
A2 Read the conversation below and draw an extra line under the words you would give extra stress to. Then practise it in pairs.
Create your own dialogue based on the following situation. Remember to give extra stress to some words. An example has been given to you.
Last Sunday, Susan met her old classmate, Sally, on her way to the cinema. Instead of watching a film, they talked in a cafe for two hours …
Susan: Long time no see. How’s everything going?
Sally: Everything is fine. You look great! What do
