A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”．This idea is dangerous．

       Science can be a force for evil as well as for good．Its applications can be channeled either way, depending on our decisions．The decisions we make, personally or collectively, will determine the outcomes of science．But here is a real danger．Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference．And, rather than fighting for the best possible policies, we may step back and do nothing．

       Some people go even further．They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ——somewhere, sometime．They believe that science will get out of control in the end．This belief is dangerous too, because it a fuels sense of hopelessness and discourages them from making efforts to build a safer world．

       In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science．Without a common understanding, the challenges of “controlling” science in this century will be really tough．Take human cloning for example．Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques．The outcomes are hard to predict．

       Therefore, discussions on how science is applied should be extended far beyond scientific societies．Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future．

What can we conclude from the recent study?

       A．People think highly of science．

       B．People hold mixed opinions about science．

       C．Science is getting dangerously out of control．

       D．Science is used for both good and bad purposes．

According to the passage, what will happen if we hold that science is getting beyond control?

       A．The development of science will hopelessly slow down．

       B．Businesses will have even greater influence on science．

       C．The public will lose faith in bringing about a bright future．

       D．People will work more actively to put science under control．

The discussion should reach beyond scientific societies because __________．

       A．scientists have failed to predict the outcomes

       B．the ties between different areas need strengthening

       C．united efforts are necessary for the development of science

       D．people need to work together to prevent the bad use of science

What is the main idea of the passage?

       A．Science and its applications bring us many dangers．

       B．The development of science mostly lies in people’s attitudes．

       C．Mankind can largely take control of science with their efforts．

       D．The future of science will be influenced by the dangerous ideas．

A letter to Edward, a columnist（报刊专栏作家）

Dear Mr Expert:

I grew up in an unhappy and abusive home. I always promised myself that I’d get out as soon as possible. Now, at age 20, I have a good job and a nice house, and I’m really proud of the independence I’ve achieved.

Here’s the problem: several of my friends who still live with their parents wish they had places like mine — so much so that they make mine theirs.

It started out with a couple of them spending the weekends with me. But now they seem to take it for granted that they can show up any time they like. They bring boyfriends over, talk on the phone and stay out forever.

I enjoy having my friends here sometimes — it makes the place feel comfortable and warm— but this is my home, not a party house. I was old enough to move out on my own, so why can’t I seem to ask my friends to respect my privacy（隐私）?

Joan

Edward’s reply to Joan

Dear Joan:

If your family didn’t pay attention to your needs when you were a child, you probably have trouble letting others know your needs now.

And if you’ve gathered your friends around you to rebuild a happy family atmosphere（气氛）,you may fear that saying no will bring back the kind of conflict you grew up with— or destroy the nice atmosphere you now enjoy. You need to understand that in true friendship it’s okay to put your own needs first from time to time.

Be clear about the message you want to send. For example, “I really love your company but I also need some privacy. So please call before you come over.”

Dear Mr. Expert,

Dear Joan,

　　If your family didn’t pay attention to your needs when you were a child, you probably have trouble letting others know your needs now.

　　And if you’ve gathered your friends around you to rebuild a happy family atmosphere(气氛), you may fear that saying no will bring back the kind of conflict（冲突）you grew up with—or destroy the nice atmosphere you now enjoy. You need to understand that in true friendship it’s okay to put your own needs first from time to time.

      Be clear about the message you want to send. For example, “I really love your company（陪伴） but I also need some privacy. So please call before you come over. ”

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.

Rainforests can help to adjust the climate because they      

A. reflect more heat into the atmosphere

B. bring about high rainfall throughout the world

C. rarely cause the temperature to drop lower than l6℃

D. reduce the effect of heat from the sun on the earth

What does the word “this” underlined in the third paragraph refer to?

A. We will lose much more than we can gain.

B. Humans have begun destroying rainforests.

C. People have a strong desire for resources.

D. Much carbon dioxide comes from burning rainforests.

It can be inferred from the text that

A. we can get enough resources without rainforests

B. there is great medicine potential in rainforests

C. we will grow fewer kinds of crops in the gained land

D. the level of annual rainfall affects wind patterns

What might be the best title for the text?

A. How to Save Rainforests

B. How to Protect Nature

C. Rainforests and the Environment

D. Rainforests and Medical Development
