A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate.Without the forest cover,these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns,potentially causing certain natural disasters all over the world.

   In the past hundred years,humans have begun destroying rainforests in search of three major resources(资源):land for crops,wood for paper and other products,land for raising farm animals.This action affects the environment as a whole.For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests.People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

   There are two main  reasons for this.Firstly,when people cut down trees,generally they can only use the land for a year or two.Secondly,cutting large sections of rainforests may provide a good supply of wood right now,but in the long run it actually reduces the world’s wood supply.

    Rainforests are often called the world’s drug store.More than 25% of the medicines we use today come from plants in rainforests.However,fewer than l%of rainforest plants have been examined for their medical value.It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

     Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are rub of black surfaces already, in the form of asphalt (柏油) roads?

     Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.

      The heat-colleetor is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.

      When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warning the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.

      In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.

 

64. Which of the following is true according to the first two paragraphs?

A. Arian de Bondt got his idea from his boss.

B. Large, flat, black surfaces need to be built in cities.

C. The Dutch engineer's system has been widely used.

65. For what purpose are the diving pipes used?

A. To absorb heat from the sun.

B. To store heat for future use.

C. To turn solar energy into heat energy.

D. To carry heat down below the surface.

 

66. From the last paragraph we can learn that __

A. some pipes have to be re-arranged in winter

B. the system can do more than warming up the building

C. the exchangers will pick up heat from the street surface

D. less heat may be collected in winter than in summer

 

67. What is most likely to be discussed in the paragraph that follows?

A. What we shall do if the system goes wrong.

B. What we shall do if there are no asphalt roads.

C. How the system cools the building in summer.

D. How the system collects heat in spring and autumn.

     The year 2009 is the Year of Ox. The ox is a representative of the fanning culture of China. In the farming economy (经济), oxen are the major animals pulling plows (犁).

     Of course, the good of oxen is not limited to plowing.  In fact, they are seen as "boats on land" for their ability to carry loads. Besides, the whole body of an ox is full of treasures. Their meat and milk are food full of nutrition, and their skin can be used to make clothes and shoes. With all these qualities, oxen are regarded as generous creatures.

     In the past, oxen played an important role in the spiritual life of the Chinese. Even today, oxen still play a special part in some folk activities. For example, some people who1ire in southwest China will cook cattle bone soup and share it among family members when holding the ceremony for children who reach 13. They believe that the cattle bone soup represents the blood relationship among family members. In order to express their love for oxen, people in some other areas will run to shake off diseases on the 16th day of the first month by the lunar calendar (农历), and during their run they will take their oxen along, which indicates they regard the creature as human.

Remembering names is an important social skill.Here are some ways to master it.

Recite and repeat in conversation.

    When you hear a person’s name,repeat it.Immediately say it to yourself several times without moving your lips.You could also repeat the name in a way that does not sound forced or artificial.

    Ask the other person to recite and repeat.

    You can let other people help you remember their names.After you’ve been introduced to someone,ask that person to spell the name mad pronounce it correctly for you.Most people will be pleased by the effort you’re making to learn their names.

    Admit you don’t know.

    Admitting that you can’t remember someone’s name can actually make people relaxed.Most of them will feel sympathy if you say.“I’m working to remember names better.Yours is right on the tip of my tongue.What is it again?”

    Use associations.

    Link each person yon meet with one thing you find interesting or unusual.For example,you could make a mental note: "Vicki Cheng -- tall, black hair. " To reinforce you’re your associations, write them on a small card as soon as possible.

     Limit the number of new names you learn at one time.

     When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.

     Go early.

     Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That's fewer names for you to remember. And as more people arrive, you can hear them being introduced to others -- an automatic review for you.

56. How will most people feel when you try hard to remember their names?
