A middle-aged stranger visited us late on a dark rainy night when my father was working the night shift (a job for a period during the night). The stranger asked if he could wait under the eaves of our roof for the rain to stop. Then he disappeared, and we started hearing footsteps and creaking boards in the attic(the space or room at the top of a building, under the roof, often used for storing things). Was the stranger inside our house? My whole body couldn’t help but stiffen. In my mind’s eye, I could imagine the stranger pushing through the attic door and approaching us.

    We immediately called Jerry, our neighbor, for help. He searched everywhere, but the visitor was nowhere to be found. As Jerry looked in the garage, he found the stranger lying underneath the car. Jerry exclaimed with fright, “You are not allowed to enter the house. Get off the property right now.”

    We were determined to leave the house immediately. As we drove away, we saw the man blocking our way on the road and staring at us. We had to swerve to miss him. After that, I never saw the stranger again.

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

Think you can walk, rive, take phone calls, email and listen to music at the same time? Well, New York’s new law says you can’t. and you I’ll be  41  $100 if you do it on a New York City street.

The law went into force last year, following recent research and a (n)  42  number of accidents that involved people using electronic devices when crossing the street.

Who’s to  43  ? scientists say that our multitasking(处理多重任务的)abilities are limited.

“We are under the impression that our brain can do more than it often can ,” says Rene Marois, a scientist in Tennessee. “But a major limitation is the inability to  44  on two things at once.”

The young are often considered the great multitaskers. However, an Oxford University research suggests this idea is open to question. A group of 18-to 21-year-olds and a group of 35-to 39-year-olds were given 90 seconds to translate  45  into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone cal or a (n)   46  message, the older group matched the younger group in speed and  47  .

It is difficult to measure the productivity lost by multitaskers. But it is probably a lot. It is estimated that the cost o interruptions to the American economy is nearly $650 lillion a year.

The   48  is based on surveys with office workers. The surveys conclude that 28 percent of the workers’ time was spent on interruptions and   49  time before they returned to their main tasks.
