题目列表(包括答案和解析)
We’ve used the wind as an energy source for a long time.
The Babylonians and Chinese were using wind power to
pump water for irrigating crops 4,000 years ago, and sailing
boats were around long before that.Wind power was used in the
Middle Ages, in Europe, to grind(磨碎) corn, which is where
the term “windmill” comes from.
We can use the energy in the wind by building a tall tower, with a large propellor(螺旋桨) on the top.The wind blows the propellor round, which turns a generator to produce electricity.We tend to build many of these towers together, to make a “wind farm” and produce more electricity.The more towers, the more wind, and the larger the propellors, the more electricity we can make.It's only worth building wind farms in places that have strong, steady winds, although boats and caravans(大篷车)increasingly have small wind generators to help keep their batteries charged.
The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains — places where the wind is strong and reliable.Some are offshore.To be worthwhile, you need an average wind speed of around 25 km/h.Most wind farms in the UK are in Cornwall or Wales.Isolated places such as farms may have their own wind generators.In California, several “wind farms” supply electricity to homes around Los Angeles.
The propellors are large, to obtain energy from the largest possible volume of air.The blades can be angled to cope with varying wind speeds.Some designs use vertical turbines (垂直涡轮机), which don’t need to be turned to face the wind.The towers are tall, to get the propellors as high as possible, up to where the wind is stronger.This means that the land beneath can still be used for farming.
1.The first paragraph aims to introduce to us _______.
A.the function of wind power B.the source of wind power
C.the nations using wind power D.the history of using wind power
2.The best places for building the wind farm are places where _______.
A.boats and caravans can often be seen B.isolated farms don’t have enough electricity
C.there are less human activities D.the wind is strong and reliable
3.We can infer from the passage that _______.
A.wind farms will not take up too much farming land
B.wind farms need no fuel because wind is free
C.the blades can be angled to turn to face the wind wherever it comes from
D.the higher and larger the towers are, the stronger the wind is
4.What can be a suitable title for the passage?
A.Where to build a wind farm. B.ABC of the using of wind energy.
C.How to make best use of wind. D.Wind energy is the best energy.
I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?” He looked perturbed (不安). “Do you want to try it first?” he said. It didn’t quite sound like a question. “Do I need to?” I replied ,“There is nothing wrong with it?” This made him look a bit insulted and I started to feel bad. “No, no. But you should try it,” he said encouragingly. “Compare it with the others.”
I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.
But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out of my chosen camera from cupboard, show how it took excellent pictures of my fellow shoppers… and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.
Why do we think that new options(选择) still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.

A. try the camera to see if there was anything wrong with it.

D. The camera would soon fall in value.
3.The writer decided to try the model he had chosen because he
A. knew very little about it.
B. didn’t trust the shop assistant.
C. wanted to make sure the one he chose would be the best.
D. had a special interest in taking pictures of his fellow shoppers.
4.I t can be inferred from the passage that in the writer’s opinion, .
A. people waste too much money on cameras
B. cameras have become an important part of our daily life
C. we don’t actually need so many choices when buying a product
D. famous companies care more about profit than quality
We don’t plan to cry, but it just happens. In fact when we feel sad or angry, a good cry is almost impossible to resist. But if you didn’t know what crying was, you’d have to wonder why some strong feelings started water streaming from people’s eyes and why they seemed to feel better afterwards.
Now a US researcher had found there may be more in crying than we think. William H. Frey II, author of “Crying: The Mystery of Tears,” believes it may really be one of the body’s clever self-repair mechanisms. Crying may be a way of getting rid of the by-products of stress, he says.
He has found that tears contain some chemicals which can cause stress. One of these is the hormone prolactin (激素), which is set free when one is feeling stressed. Since women have more of this than men, that might explain why they usually cry more, he suggests.
Unsurprisingly, Dr Frey’s study seemed to prove that most people feel better after a good cry. And sex has nothing to do with it ––– the result was true for women and men. So, next time you feel like bursting into tears, go ahead. If Dr Frey is right, you’ll be doing yourself a favour.
