九年级英语单项填空简单题查看答案及解析

(C)

Pollution inside homes and other buildings kills more than 4 million people each year. Many people die as a result of breathing smoke or from cooking over wood-powered or coal-powered stoves.

One way to reduce the number of deaths is through cooking equipment powered by the sun. Crosby Menzies, a solar power expert in a South African company, described his latest solar cooker called the "Sol-4". "It is four square meters of mirrors, six to eight meters in length. It is quite a large cooker. "

The "Sol-4" works by reflecting (反射) light from the sun off large mirrors. The mirrors direct (把……对准) the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.

The cooker is also much "friendlier" than other models because people do not have to stand in the sun to use it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals （人）would be less likely to have breathing illnesses from harmful smoke.

At present, the cooker only works when the sun is shining. But engineers are working on a way to make it work without sunlight.

Each cooker costs about $2,000, which is a large amount of money for most Africans. To solve that problem. Crosby Menzies has created a non-governmental organization called Solar Cookers for Africa. It plans to raise money through donations to provide poor people with solar cooking equipment.

1.This passage is mainly about _______ .

A. solar cooker B. smoke pollution C. solar power experts D. breathing illnesses

2.The "Sol-4" is mainly used to _______ .

A. shorten the time of cooking

B. reduce the cost of making cookers

C. raise money through donations to help African people

D. reduce the number of deaths caused by harmful smoke

3.Which of the following about the "Sol-4" is TRUE?

A. It is six to eight square meters of mirrors.

B. It can work in any weather condition now.

C. It can also heat the pan by lighting firewood.

D. It is more environment-friendly than other cookers.

4.From the passage, we can infer that _______ .

A. the "Sol-4" will be designed in a smaller size

B. more Africans can use the solar cookers in the future

More than 30,000 drivers and front seat passengers are killed or seriously injured each year. At the speed of only 30 miles per hour, it is the same as falling from a third-floor window. Wearing a seat belt（安全带） saves lives; it reduces your chance of death or serious injury by more than half in traffic accidents.

So drivers or front seat passengers over 14 years old in most vehicles(车辆) must wear a seat belt. If you do not, you could be fined(罚金) up to ￡50. It will not be up to the drivers to make sure you wear your belt. But it will be the driver’s duty to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.

However, you do not have to wear a seat belt if you are reversing your vehicle（倒车）; or if you are a postman using a special vehicle; or if you have a valid medical certificate which allows you not to wear it. Make sure about all the above before you decide not to wear your seat belt. Remember you may be taken to the police station for not doing so.

1.This text is most probably taken from ________.

A. a medical magazine　　　　　　　　     B. a police report

C. a diary　　　　　　　　　　　　　　　　     D. a story book

2. Wearing a seat belt in a vehicle ________.

A. reduces road accidents by more than half

B. saves lives while driving at a speed up to 30 miles per hour

C. reduces the chance of death in traffic accidents

D. saves more than 15,000 lives each year

3.It is the driver’s duty to ________.

A. make the front seat passenger wear a seat belt

B. make the front seat children under 14 wear a seat belt

Tornadoes(龙卷风) are one of the worst weather events on earth. Each year, tornadoes kill many people. The storms often carry homes, cars and trees from one place to another. And they can also destroy anything when they pass by.

A tornado comes from a thunderstorm(雷雨) in the sky down to the ground. It is big at the top and small at the bottom.

A tornado appears when winds in different directions meet in the cloud and begin to turn in circles. People can see tornadoes almost everywhere in the world. But most happen from late winter to middle summer. There is a second high season in November. During spring, warm air moves north and mixes with the cold air left from winter. In November, the opposite happens. Cold air moves south and mixes with the warm air left from summer.

Tornadoes always come suddenly. Weather scientists have done something to predict(预测) tornadoes. But the storms often move too fast for people to protect themselves. Last year, tornadoes killed more than one hundred people in United States.

Scientists say the best place to be in is a small room, without windows, in the middle the lowest part of a building when tornadoes come.
