The earth is the only planet that scientists think has life. Why does the earth have life while the other planets (行星) don't? For one thing, the earth is just the right temperature. As the_third_planet from the sun, the earth seems to be just the right distance away. The planets which are closer to the sun are hot that their surfaces bake (烘烤) in the sun. The farthest planets are cold balls.

When the earth developed — which scientists believe may have happened about 4 billion years ago — many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.

Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special space suit, you could walk around on Mars. You would have to bring your own air to breathe, the air on Mars is too thin to breathe.

Mars has the largest volcano (火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected (未预测到的) sight on Mars is dried up river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far.

1.Which of the following is NOT the reason that the earth has life?

A. The earth is just the right temperature.

B. The volcanos on earth are lower than those on Mars.

C. There is oxygen in the atmosphere of the earth.

D. The earth seems to be just the right distance away from the sun.

2.The underlined phrase “the third planet” in the first paragraph refers to ________.

A. the Sun　　　　　　　　　     B. the Moon

C. the Earth　　　　　　　　     D. the Mars

3.Which of the following about the Mars is NOT true?

A. There could have been living things on Mars.

B. Mars has the largest volcano in the solar system.

C. There is almost no oxygen in the air on Mars.

D. Mars is smaller than the earth, and it is quite a bit cooler.

高一英语单项填空简单题查看答案及解析

While scientists are worried that humans are causing higher temperatures on the Earth, a Maryland man, Ace, thinks we can save the world by spraying（喷射）huge amounts of water into the air.

Ace told the McClatchy News Service that at least 1,000 places should be chosen to spray water. The water would be sprayed between 20 and 200 feet into the air. Thousands of tons of seawater would be sprayed for years at a time.

The 1,000 sites would be picked after more studies. They would be mostly in the Northern Hemisphere(北半球). Ace says he would avoid tropical（热带的）areas of the globe. He says water turns to rain too quickly in these areas for his plan to work.

The water would be changed into vapor. That process requires heat. The water vapor would rise above the Earth. The water vapor would form clouds. The clouds would help in several ways. They would cool the Earth by reflecting sunlight. They would later turn into rains. The rains would provide another way of cooling the Earth.

Ace’s plan has gotten some support from a limited scientific study. Kenneth Caldeira is a climate scientist. He works at the Carnegie Institution’s Department of Global Ecology at Stanford University in California. Caldeira tested some of the Ace’s figures on a computer program. The computer model is used by top scientists to study global climate change. The model showed that the plan might work.

“More tests are planned in 2009. Ideas like Ace’s should be considered carefully and with an open mind,” Calderira said. “Every brilliant（卓越的）invention in the history of technology looked a little bit mad when first put forward.”

65．What’s the purpose of Ace’s plan?

A. To reduce air pollution.

B. To make summer cooler.

C. To offer dry areas more rain.

D. To solve the problem of global warming.

66．According to Ace’s plan,___________.

A. planes would be used to spray water.

B. it would be best to spray water on rainy days.

C. seawater would be sprayed high into the sky

D.1,000 sites in the Southern Hemisphere would be chosen.

67．Why wouldn’t Ace spray water in tropical areas?

A. Water is changed into vapor too quickly.

B. Water turns to rain too quickly.

C. It is hard for vapor to form clouds.

D. It is bad for local plants to have too much rain.

68. It seems that Caldeira ____________.

A. takes Ace’s plan seriously

B. thinks Ace’s idea too crazy

C. doesn’t believe the computer’s result

D. agrees to carry out Ace’s plan right away
