Some plants get so hungry they eat flies,spiders,and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact,they're found on every continent except Antarctica.

You've probably seen a Venus' flytrap (捕蝾草) .It's often sold in museum gift stores,de?partment stores,and even supermarkets. A small plant,it grows 6 to 8 inches tall in a contain?er. At the end of its stalks (茎) are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger (触发) hairs. When an insect lands on them,the trap suddenly shut. Over the course of a week or so,the plant feeds on its catch.

The Venus' flytrap is just one of more than 500 species of meateating plants,says Barry Meyers-Rice,the editor of the International Carnivorous Plant Society's Newsletter. Note: Despite any sciencefiction stories (科幻小说) you might have read,no meateating plant does any danger to humans.

Dr. Meyers-Rice says a plant is meateating,only if it does all four of the following： " at?tract,kill,digest,and absorb" some form of insects,including flies,butterflies,and moths. Meateating plants look and act like other green plants―well,most of the time.

All green plants make sugar through a process called photosynthesis (光合作用) .Plants use the sugar to make food. What makes " meateating" plants different is their bugcatching leaves. They need insects for one reason;nitrogen (氮) .Nitrogen is a nutrient that they can't obtain by any other way. Why?

Almost all green plants on our planet get nitrogen from the soil. " Meateating" plants can't. They live in places where nutrients are hard or almost impossible to get from the soil be?cause of its acidity (酸度) .So they've come to rely on getting nitrogen from insects and small animals. In fact,nutrientrich soil is poisonous to "meateating" plants. Never fertilize (施肥) them!But don't worry,either,if they never seem to catch any insects. They can survive,but they'll grow very slowly.

Efforts to educate people about the risks of substance abuse (毒品滥用) seem to deter (阻止) some people from using dangerous substances,if such efforts are realistic about what is genuine?ly (真正地) dangerous and what is not. Observed declines in the use of such drugs as LSD(摇头丸) ，PCP(迷幻药) ，and Quaalude (安眠酮) since the early 1970s are probably related to in?creased awareness of the risks of their use,and some of this awareness was the result of warn?ings about these drugs in " underground" papers read by drug users. Such sources are influential (有4艮大的影响) ，because they do not give a simple " all drugs are terrible for you" message. Drug users know there are big variations (变化) in danger among drugs,and antidrug education that ignores or denies this is likely to be ridiculed. This is illustrated by the popularity among young marijuana (大麻) users of Reefer Madness,a widely unrealistic propaganda (宣传) film against marijuana made in the 1930s. This film made the rounds of college campuses in the 1970s and joined rock music videos on cable television's MTV in the 1980s. Instead of deterring mari?juana use,it became a cult (风靡一时的) film among users,many of whom got high to watch it.

Although persuasion can work for some people if it is balanced and reasonable,other peo?ple seem immune to the most reasoned educational efforts. Millions have started smoking even though the considerable health risks of smoking have been well known and publicized for years. Moreover,the usefulness of education lies in primary prevention：prevention of abuse among those who presently have no problem. Hence,Bomier's contention (看法，观点) that "if the Pepsi generation can be persuaded to drink pop wine,they can be persuaded not to drink it while driv?ing" is probably not correct,since most drunken driving is done by people who already have significant drinking problems,and hence seem not to be dissuaded (劝阻) even by much stronger measures such as loss of a driver's license.

   A. has made all people see the danger of drugs

   B. has succeeded in dissuading people from using drugs

   C. has been effective only to a certain degree

   D. has proved to be a total failure

(   ) 6. What is the main reason to stop some people from using drugs?

   A. Efforts to reduce drug using.

   B. Increased awareness and warning of the risk of their use.

   C. Punishments seem to be an effective way.

   D. Primary prevention is a useful method.

(   ) 7. The message "all drugs are terrible for you" is not influential because         .

   A. it ignores the fact that drugs vary greatly in danger

   B. it gives a false account of the risks of drug use

   C. some drugs are good for health

   D. it does not appear in underground papers

(   ) 8. Which of the following might be the best title for the passage?

   A. Are All Drugs Terrible for You?

   B. Do People Believe What Underground Papers Say?

   C. Is There an Increased Awareness of the Risks of Drugs?

I just finished taking an evening class at Stanford. The last lecture was on the mindbody connection―the relationship between stress and disease. The speaker (head of psychiatry (精神病学) at Stanford) said,among other things,one of the best things that a man could do for his health is to be married to a woman,whereas for a woman,one of the best things she could do for her health was to nurture (培育) her relationships with her girlfriends. At first everyone laughed,but he was serious.

Women connect with each other differently and provide support systems that help each other to deal with stress and difficult life experiences. Physically this quality "girlfriend time" helps us to create more serotonin一a neurotransmitter (神经传递素) that helps combat depression and can create a general feeling of well being. Women share feelings whereas men often form relationships around activities. They rarely sit down with a buddy (伙伴) and talk about how they feel about certain things or how their personal lives are going. Jobs? Yes. Sports? Yes. Cars? Yes. Fishing,hunting,golf? Yes. But their feelings? Rarely. Women do it all of the time. We share from our souls with our sisters,and evidently that is very good for our health. He said that spending time with a friend is just as important to our general health as jogging or working out at a gym.

There's a tendency to think that when we are "exercising" we are doing something good for our bodies,but when we are hanging out with friends,we are wasting our time and should be more productively engaged―not true. In fact,he said that failure to create and maintain quality personal relationships with other humans is as dangerous to our physical health as smoking!So every time you hang out to schmooze (闲谈) with a gal pal,just pat yourself on the back and congratulate yourself for doing something good for your health!We are indeed very very lucky. So let's toast to our friendship with our girlfriends. Evidently it's very good for our health.

(   ) 5. It can be concluded that women tend to share feelings to deal with stress whereas men

   A. often sit down with a friend to talk about their feelings

   B. seldom share their feelings of depression with friends

   C. sometimes exchange their feelings about personal lives with friends

   D. always do different activities to combat depression with friends

(   ) 6. The underlined phrase "working out" in the second paragraph most probably means

   A. figuring out the algebra problems 

   B. puzzling out the answer to the problem 

   C. doing physical exercise  

   D. solving the difficult problem

(   ) 7. The purpose of the first paragraph is to show that         .

   A. marriage is good for men while relationships with girlfriends essential for women to be healthy

   B. it is a best thing for men and women to get married in order to keep healthy

   C. the speaker was serious to talk about the relationship between stress and disease

   D. one of the best things women could do for health was to nurture the relationships with boyfriends

(   ) 8. What can we learn from the last paragraph?

   A. "Exercising" good for our bodies, "hanging out" wasting our time.

   B. A disagreeable relationship with other persons is similarly dangerous to our health.

   C. We have reasons to toast to the friendship with our girlfriends.

   D. Hanging out with friends should be more productively engaged.

T-shirts Out; Uniforms In School uniforms are becoming more and more popular across theU. S. A. That's no sur?prise,because they offer many benefits. They immediately end the powerful social sorting and labeling (标记) that come from clothing. If all students are dressed in the same way,they will not pay too much attention to their clothing,and some of them will not be laughed at for wear?ing the " wrong" clothes.

Some people are against the strict rule of school uniforms,but they do not realize that students already accept a kind of rule―wanting to look just like their friends. The difference is that the clothing students choose for themselves creates social barriers;school uniforms tear those barriers down.

As in other places,uniforms remind the wearers of their purposes and duties. For example,when a man or woman puts on a police uniform,he or she becomes,for a time,the symbol (象征) of law and order. The uniform means to the wearer his or her special duties and sends the same message to everyone the wearer meets. People with different jobs wear uniforms of one kind or another. For students,the school uniform reminds them that their task for the six or seven hours they are in school is to get an education.

Some parents are unhappy about uniforms,saying that school uniforms will affect their children's "creativity". First,as noted above,the clothes students choose to wear do not necessarily express their individuality (个性) .They just copy their classmates. Second,students have the rest of the day to be as creative as they like. While they're in school,their job is to master reading,writing,and maths; this should take up all the creativity they have. Mastery of those skills will be good for the students to build up their creativity in every way.

(   ) 5. The purpose of the first paragraph is to show that the author         .

   A. is in favor of this course of action

   B. does think poorly of it

   C. thinks nothing of the method of doing it

   D. strongly opposes the way of doing it

(   ) 6. What is the meaning of the underlined word "benefits" in Paragraph 1?

   A. Interests. B. Rewards. C. Personalities. D. Advantages.

(   ) 7. According to the passage,what is the theme of uniforms in general?

   A. They can prevent the wearers from being laughed at.

   B. They will help the wearers keep their duties in mind.

   C. They are seen as a symbol of power.

   D. They help to tear those barriers down.

(   ) 8. Some people are against school uniforms because         .

   A. they fail to realize that students have accepted the uniforms

   B. they believe that uniforms will make students less creative

   C. they don't agree that uniforms can remove social barriers
