Composition
Predicting what computers will be like in 20 years' time or what they will be able to do is a guessing game. If Leon Bagrit could not predict everything, what chance have I got? However, becau prediction is just a calculated guess, I will try!
The development of the computer since the 1960s has been very fast. Prom large mainframe computers which filled whole rooms to small lap-top computers which you can carry in a shoulder bag or large handbag, it has taken only forty years. Computers are already smaller, more powerful and cheaper than they have ever been. So what might happen in the next twenty years? Let's speculate.
In twenty years' time it's possible that many people will be doing their everyday shopping by computer. The "virtual-reality" shop will be available through your TV t. You will be a
ble to "walk through" your supermarket on screen, click or tick what you want, and then order it — and it will be delivered. In education, most students could be using computer-notebooks which make notes for them as they listen to a lecture or watch a demonstration experiment. In the world of travel, aircraft already have computer systems that will control auto-pilot In twenty years' time, computers could actually pilot aircraft — with no need for a real, live human pilot at all.adventure
Computers already help doctors diagno dia and other health problems, and help in the control of body systems during operations. What el might they do in the future? They might actually control certain kinds of surgery (brain surgery, for example) where the human hand cannot always keep still enough, and power computer-operated limbs.
So there are some ideas. But who knows what might really happen? No one. No one can e into the future. We shall just have to wait and e. (307 words)

Conclusion: How I felt when I got home Composition
For me, a day's shopping is the best way I think of to pass a day away from college or wo在职研究生和全日制研究生的区别
rk. I have been looking forward to a day out shopping for weeks becau I have wanted to get some new clothes for ages, so last Friday I took a day off.
I got up at the usual time (as if I were going to work or college) becau for me shopping is as rious as work. Before I left the hou I made sure I put on a good pair of walking shoes and then caught the bus into the centre of the town.
Some people visit all the shops in the hope that they will find what they want at the prices they want to pay. Not me: I'm one of tho shoppers who has a list of purchas — and with a fairly good idea of how much I want to pay.

By the time I got home, it was six o'clock. I was absolutely exhausted, but plead that I had managed to buy two things on my list.
