Question

先通读下面的短文，然后根据短文内容，在文章后表格的空格内填入一个最恰当的单词。所填单词必须写在答题卡对应题号的横线上。每个空格只能填一个单词。

People have been using the wind’s energy for a long, long time. More than 5, 000 years ago, ancient Egyptians made boats powered by the wind. In 200 B.C., people used windmills(风车) in China.

Today, we collect the wind’s energy with wind turbines(涡轮). A turbine is similar to a windmill; it is a very tall tower with two or three blades(叶片) at the top. These blades are turned by the wind. The blades turn a generator(发电机) located inside the tower, which creates power.

Groups of wind turbines are known as wind farms. Wind farms can be found near farmland, in narrow mountain passes, and even in the ocean, where there are stronger winds. Wind farms create power for nearby homes, schools and other buildings.

In places like the Midwest and along coasts, winds can provide cheap power. Another great advantage of wind power is that it is a clean form of energy. Wind turbines do not burn oil or coal and do not pollute the air.

Wind is not always an ideal source of energy, however. Wind speed changes from time to time, depending on the time of day, weather and location. Wind turbines can be also dangerous for bats and birds. These animals cannot always tell how fast the blades are moving and crash into them.

Title: 1. Energy

Ancient times	➢ People in Egypt made wind-powered boats 2. 5,000 years ago. ➢ People in China used windmills in 200 B.C.
Modern times	➢ It is 3. with turbines, which are tall windmill-like towers with two or three blades at the top and a generator inside. ➢ The wind turns the blades and the blades turn the generator to create power.
Advantages	➢ Winds produce power at a low 4. in certain areas. ➢ Wind turbines do not cause air pollution.
Disadvantages	➢ Wind speed does not remain at the same 5. all the time. ➢ Wind turbines can be dangerous for animals like bats and birds.

3.collected

4.cost

5.level

【解析】

本文是一篇说明文，介绍了人类从古至今对风能的利用。

1.

通读全文可知，本文是一篇说明文，介绍了人类从古至今对风能的利用。故此处标题为“风能”，且首字母应该大写。故答案为Wind’s。

2.

根据原文More than 5, 000 years ago, ancient Egyptians made boats powered by the wind可知，5000多年前，古埃及人就制造了风力驱动的船只。故此处说的是5000多年前，古埃及人制造了风力驱动的船只。答案只能填一个词，故答案为over。

3.

根据原文Today, we collect the wind’s energy with wind turbines可知，今天，我们用风力涡轮机收集风能。故此处用被动语态说的是风能被风力涡轮机收集。故答案为collected。

4.

根据原文In places like the Midwest and along coasts, winds can provide cheap power可知，在中西部和沿海地区，风能可以提供廉价的电力。故此处说的是在某些地区，风能可以以低成本发电。故答案为cost。

5.

根据原文Wind speed changes from time to time, depending on the time of day, weather and location可知，风速随时间的变化而变化，这取决于一天中的时间、天气和地点。故此处说的是风速并非一直保持在同一水平。故答案为level。
