During the scientific experiment, Mr. Chen carefully poured the water into the tube, with my classmates _______ beside to see what would happen.   

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

Weather changes when the temperature and the amount of water in the atmosphere change. We can see and feel water coming from the atmosphere when we have rain. But the water must somehow get back to the atmosphere. Meteorologists call this the water cycle.

   There are many stages in the water cycle. Rain falls when water vapour in clouds condenses(凝结). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground and in the rivers, lakes, and the sea. It changes the liquid water into water vapour. The vapour rises onto the air. Water vapour is normally invisible. On a very damp or humid day, however, you can sometimes see water vapour rising from a puddle(水坑) or pond in a mist(薄雾) above the water. Water vapour also gets into the air from living things. Trees and other plants take in water through their roots and give off water vapour from their leaves. People and land animals drink water and breathe out water vapour. In all these ways the water returns to the air. There it gathers to form clouds and condenses to form rain. The rain falls to earth, and the cycle starts again. It continues even if snow or hail(冰雹) fall instead because both eventually melt to form water. The amount of water vapour in the air depends on the temperature. The air is more moist(潮湿) in the tropics(热带) than in the cold polar regions.

1. What is the main idea of the passage?

A. Water cycle.                                 B. Water vapour.

C. How rain forms.                      D. Water, vapour, rain.

2. How many ways of the water returning to the air are discussed in the text?

A. Two.                  B. Three.        C. Four.        D. Five.

3. Whether water vapour can be seen or not depends on _______.

A. how much water is evaporated         B. how good your eyes are

C. in which way water is evaporated           D. climate or weather

4. From the passage we get to know _______.

A. there is more water vapour in the air in the tropics than in cold polar regions

B. there is more water vapour in the air in cold polar region than in the tropics

C. it gets more rain in the tropics than in cold polar regions because there is less vapour

D. the amount of water vapour in the air depends on how often it rains

Lucy complained to her father about her hard life. She wanted to  36 because she didn’t know how to______37___ her problems. She felt tired of fighting and fighting. Once one    ___38____  had been solved, another came.

Her father, a cook, took her into the ___39____. He poured water into three pans. After the water ___40____, in the first pan he put some carrots, the second some eggs, and in the __41____ some coffee. He waited without any   42  .

The girl closed her mouth and waited,   43 by what her father was doing. After about twenty minutes, her father    44 the stove and took out the carrots and the eggs. Then the coffee was ____45___ into a cup.

Turning back to his daughter, he asked, “what do you  46  ?”

“Carrots, eggs, and coffee,” she answered.

Her father suggested she   47   the carrots. She did, and felt the carrots were   48 . Then he asked her to take the eggs and   49 them. After peeling（剥）them, she felt that the eggs were hard.  Lastly, he asked her to smell the __50____. She asked impatiently  , “What’s the meaning of this, father?” He explained that   51  had felt the same misfortune to be put into the __52___ water， but had reacted   53 .
