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 vapor in clouds condenses(凝結(jié)). 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(薄霧) 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(潮濕) in the tropics(熱帶) than in the cold polar regions.

What is the main idea of the passage?

A. Water cycle.                                  

B. Water vapour.

C. How rain forms.                  

D. Water, vapour, rain.

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

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

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

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

Energy is very important in modern life. People use energy to run machines, heat and cool their homes, cook, give light, and transport people and products from place to place. Most energy comes from fossil fuels—petroleum, coal, and natural gas. However, burning fuels causes pollution. Also, if we don’t find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be?
Energy from the wind
All over the world, people use the power of the wind. It turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy.
Energy from water
When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40,000people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive.
Energy from the earth
There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world.
Energy from the sun
Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy.
【小題1】What does this passage mainly talk about?

A.Advantage of the energy from nature.
B.The future of the energy.
C.Scientists have been working hard to research other kinds of energy.
D.Energy is the most important power in the word.
【小題2】From the first paragraph we know ______.
A.energy can do everything for people
B.a(chǎn)ll the energy causes pollution
C.the new kinds of energy are badly needed
D.scientists have found other kinds of energy for the future
【小題3】What is the writer’s opinion about the energy?
A.Try to use water energy more though it costs a lot.
B.Each natural energy has its own advantages and disadvantages.
C.Solar power is environmental.
D.Wind power is the cheapest but we can’t get.
【小題4】What can be inferred from the passage?
A.In order to protect our environment, we should try other kinds of energy.
B.All scientists in the world will unite to find energy.
C.People in modern life use energy every day.
D.Energy changes people’s lives.

根據(jù)短文內(nèi)容, 從下框A~F選項(xiàng)中選出能概括每段主題的最佳選項(xiàng),并在答題卡上將該選項(xiàng)涂黑。選項(xiàng)中有一項(xiàng)為多余項(xiàng)。

 

A. Control of respiration

B. Basic tips for preserving cut flowers

C. Role of respiration

D. Most important aspect of flower care

E. Need for clean water

F. Ways of stopping respiration

 

1.______________

While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple facts. The key to keeping fresh cut flower for a week or more without preservatives ( which contain biocides (殺蟲劑) that kill bacterial and fungus) is to keep the water fresh and the stems free of air pockets so they can continue to draw up water.

2._____________

  An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowered at the right temperatures is probably the most important aspect of flower care.

3._____________

  The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), supplies the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all living things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies.

4.______________

  How, then, to control the speed at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature, we know that respiration produces heat, but the reverse ( 反面 ) is also true. Thus by keeping low temperatures, respiration is reduced and the cut flower will age more slowly.

5._____________

  Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to “drink” water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, chlorine bleach ( 含氯漂白劑 ) can be used in small quantities. It is recommended that 15 drops of chlorine bleach be added to each liter of water. The water and solution ( 溶液 )should also be replaced each day.

“Yes, madam, your husband ran into some trouble,” he replied. “They were caught in a heavy storm.” .Storms often cause trouble. When I was a baby, Dad had to spend long weeks at sea as a fisherman. One day, I suddenly began to cry loudly. No matter how Mom comforted me, I just kept crying. Mom felt uneasy. A feeling told her that something bad would happen. Then a word hit her----“Mayday”. Mom called the Coast Guard, asking the man on duty about my Dad and his ship.

Father and his crew radioed for help when water started pouring in his ship. We flew out there about an hour ago and dropped them a pump. “Take it easy. He will be back soon.” “What if the pump doesn’t work?” Mom questioned. “You should do another fly-over.” The man tried to comfort Mom, “He must be all right now, Mrs Hemingway, or we would have heard a radio signal from him.” “You haven’t got a Mayday?” “No, but we will let you know if we hear the radio signal.” Mom hung up.

I remained crying. Mom called the Coast Guard again. Finally, they said they would send out a rescue plane.

At midnight the phone rang. It was the Coast Guard. They had found my father and all his crew floating in sea 15miles off Jamaica. Dad’s ship had sunk, but fortunately all were safe.

“The pump they dropped didn’t work fast enough,” Dad said. “I radioed a Mayday, but I couldn’t get through.”

Dad didn’t get through to the Coast Guard because of the storm, but he got through to us. Really, there is something that can’t be seen but exists, as is said but can’t be explained, between us, the families. 

55. The underlined word “Mayday” in the first paragraph probably means “_________”.

A. a radio program                                        B. the signal for help   

C. the holiday in May                                           D. a sign of feeling sick

56. Why did the man on duty say the author’s father would return soon?

A. The pump they dropped was of high quality.

B. The author’s father called him and told him so.

C. The plane waited until the pump worked.

D. He thought no news was good news.

57. We can infer from the text that _________.

A. the man on duty in the Coast Guard was careless

B. the plane failed to find the ship which was in danger

C. the author’s father was in charge of the ship

D. the pump saved the author’s father finally

58. What may be the explanation for the author’s (as a baby) crying?

A. He might feel hungry in the evening

B. He might see something terrible in the room.

C. He might be afraid when left alone in room

D. He might have a feeling of uneasiness.
