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.
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
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
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
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.
The underlined sentence in the last paragraph means______________________.
A. The blades can increase wind speeds
B. The blades can decrease the wind speeds
C. The speed of blades can be changed.
D. The blades can be adjusted to face different wind speeds

阅读文章后，从第50至54题所给A、B、C、D四个选项中，选出最佳答案。
We all hate speed cameras，don’t we？They’re not there to slow drivers down and lower the road accidents；they just make money for the government．They trick us，cost us cold hard cash，disturb us from driving properly and are unfair．
Well，here’s a surprising thing：what if there were facts that the boring cameras actually saved lives？It’s a conclusion difficult to ignore when you look at what’s happening in France，a country with a historically poor record of road safety．
There were 16,617 road deaths in 1972 in France for example，but that dropped to 8412 by 1995 following rules such as compulsory（强迫的）seat belt wearing in 1990 and a lowering of the blood alcohol limit to 0.05 in 1995．
Last year, the road deaths dropped below 5,000 for the first time，or 4.9 percent less than2004．Comparing road deaths to populating in 2005，that’s about 817 per million people compared with Australia’s 806．
And guess what？Last year the number of speed cameras on French roads reached 1,000 and the government plans to double that within the next three years．
Okey, you know the arguments on the increased traffic safety and cameras. for-inco me, but in seems in France there’s been a major cultural change brought on by radars and other laws. A theer-hour, wine-soaked lunch with a quick rush back to the office is no longer on.
Traveling on the highways，it is rare to see anyone breaking the 130km/h speed limit when one few traveled below it. The speed cameras are clearly signed so drivers know when they are coming There’s even all official web site listing fixed and mobile camera locations and it is updated regularly
Maybe it is because of such transparency by government，rather than the secrecy too often used by authorities in many other countries that more French can enjoy their life thanks to speed cameras
1.We can learn from the first paragraph that ．
A．speed cameras cost us our lives
B．speed cameras help HS drive properly
C．most people think speed cameras are good for slowing drivers down
D．most people think speed cameras are used to make money for the government
2.In France, a driver should obey the following rules EXCEPT ．
A．blood alcohol limit lowering B．speed limit obeying
C．camera location updating D．seat belt wearing
3.The underlined word ‘‘transparency’’ in the last paragraph is closest in meaning to ．
A．honesty B．openness C．innocence D．strictness
4.Now you can seldom see in France ．
A．lunch time last long with drunk people rushing back to office
B．people drive at a speed of less than 130 km／h
C．drivers drive according to the traffic lights
D．police conduct traffic in streets
5.What is the text mainly about？
A．The argument on speed cameras
B The drivers in France hating speed cameras
C．France does successfully in controlling road accidents
D．France takes many measures in controlling road accidents
