请同学们阅读下面的短文，然后完成后面的阅读任务。

　　Salvia Earle, a marine botanist and one of the foremost deep-sea explorers, has spent over 6, 000 hours, more than seven months, underwater．From her earliest years, Earle had a fascination for marine life, and she took her first plunge into the open sea as a teenager．

　　In the years since then she has taken part in a number of landmark underwater projects, from exploratory expeditions around the world to her well-known“Jim dive”in 1978, which was the deepest solo dive ever made without cable connecting the diver to a support ship at the surface of the sea．

　　Clothed in a Jim suit, a suit of plastic and metal armor, which was secured to a manned submarine, Salvia Earle plunged vertically into the Pacific Ocean, at times at a speed of 100 feet per minute．On reaching the ocean floor, she was released from the submarine and from that point her only connection to the sub was an 18-foot rope．For the next two and a half hours, Earle roamed the seabed taking notes, collecting specimens, and planting a U．S．flag．Having an irresistible desire to descend deeper still, in 1981 she became involved in the design and manufacture of deep-sea submersibles, one of which took her to a depth of 3,000 feet．This, however, did not end Sylvia Earle’s accomplishments．

请同学们阅读下面的短文，然后完成后面的阅读任务。

　　What will man be like in the future－in 5 000 or even 50 000 years? We can only make a guess, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time．

　　Let us take an obvious example．Man, even five hundred years ago, was shorter than he is today．Now, on average, men are about three inches taller．Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller．

　　Again, in the modern world we use our brains a great deal．Even so, we still make use of only about 20％ of the brain’s capacity．As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones．This is likely to bring about a physical change till the head, in particular the forehead, will grow larger．

　　Nowadays our eyes are in constant use．In fact, we use them so much that very often they become weaker and we have to wear glasses．But over a very long period of time it is likely that man’s eyes will grow stronger．

　　On the other hand, we tend to make less use of our arms and legs．These, as a result, are likely to grow weaker．At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life．

　　But what about hair? It will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer．In the future, then, both sexes are likely to be bald．

　　Perhaps all this gives the impression that future man will not be a very attractive creature to look at．This may well be true．All the same, in spite of all these changes, future man will still have a lot in common with us．He will still be a human being, with thoughts and emotions similar to our own．

(1)

The passage tells us about _________．
[　　]
A．	how man’s life will be in the future
B．	how future man will look like
C．	the fact that man’s organs will function differently in the future
D．	the fact that man is growing uglier as time passes

(2)

Man’s forehead will grow larger because _________．
[　　]
A．	he will use only about 20％ of the brain’s capacity
B．	the other 80％ of his brain will grow in due time
C．	he had a rather narrow forehead a few hundred years ago
D．	he will have to use his brain more and more as time goes on

(3)

Future man will probably _________．
[　　]
A．	have smaller eyes
B．	have stronger eyes
C．	see better
D．	have to wear better glasses

First aid

　　First aid is the emergency(紧急)care for a victim’s(受害人)sudden illness or injury until more skillful medical treatment is available．First aid may save a life or improve certain vital(生命攸关的)signs including pulse, temperature, an unobstructed airway, and breathing．In minor emergencies, first aid may prevent a victim’s condition from worsening and provide relief(解除)from pain．First aid must be carried out as quickly as possible．In the case of the seriously injured, a few minutes can make a difference between a complete recovery and the loss of life．

　　First-aid measures depend upon a victim’s needs and the provider’s level of knowledge and skills．Knowing what not to do in an emergency is as important as knowing what to do．Improperly moving a person with a neck injury, for example, can lead to the everlasting spinal injury and paralysis(永久性脊髓伤害和瘫痪)．

　　Despite the variety of injuries possible, several principles of first aid can be used for all emergencies．The first step is to call for the professional medical help．The victim, if conscious(有知觉的), should be reassured that medical aid has been requested, and asked for permission to provide any first aid．Next, assess(估计)the scene, asking other people or the injured person’s family or friends about details of the injury or illness, any care that may have already been given, and preexisting conditions(原先就存在的疾病)such as diabetes(糖尿病)or heart trouble．Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim．

　　First aid requires rapid assessment(估计)of victims to determine whether life threatening conditions exist．One method for evaluating(估计)a victim’s condition is known by the acronym(只取首字母缩写词)ABC, which stands for：

　　A－Airway：Is it open and unobstructed?

　　B－Breathing：Is the person breathing? Look, listen, and feel for breathing．

　　C－Circulation：Is there a pulse? Is the person bleeding externally(体表上)?Check the skin color and temperature for the additional indications of circulation problems．

　　Once the obvious injuries have been evaluated, the injured person’s head should be kept in a neutral position in line with the body．If no evidence exists to suggest the potential skull(头骨)or spinal injury, place the injured person in a comfortable position．Positioned on one side, a victim can throw up without choking(窒息)or obstructing the airway．

(1)

The underlined word “unobstructed” has the closest meaning to _________．
[　　]
A．	choke
B．	stuck
C．	free
D．	freely

(2)

When can we move the victim?
[　　]
A．	When the victim is in a dangerous surrounding．
B．	When the victim doesn’t breathe．
C．	When the victim has the spinal injury．
D．	When the victim suffers a skull injury．

(3)

Which is the first step when you meet such a victim?
[　　]
A．	Checking the victim’s ABC．
B．	Calling for the professional medical aid．
C．	Positioning the victim’s head properly．
D．	Doing first aid immediately．

　　Love the Job

　　Every day we hear about people making radical(根本的)career changes．We have our choices, but will all these changes make us any happier? Maybe the question is not “How can I get the job I love?”, but “How can I love the job I have?” Take some time to think about it, and you might be surprised by what you find．

　　1．Realize that your job does not define(给……下定义)you, but how you do it does．There’s a lot to be said for attitude, more than will fit here．Any job can be done well, if done with compassion(激情), done with care．Your attitude at work and the way you treat people－even your mood－do not go unnoticed．They have a profound influence on the people you work with．There are times when you can’t control your situation, but you can always choose how you live in it．

　　2．Stop focusing on the money．Money will never be enough so stop using it(or the lack of it)as an excuse．Whatever you are bringing home on the 15th and 30th, there are always going to be things you could do or would do if you had more．Try taking tracking(跟踪)every penny you spend in a week．Seeing where your money is really going can help you to refocus your spending towards the things you really want．Getting paid is only one small part of what you do; your work has to be more than just a paycheck(付薪水的支票)．

　　3．Find the importance in what you do．This may require you to think big, but it can be done．Take some time to really think about what you do．Do you provide an essential(必要的)service?Do you get to see the finished product?Then ask yourself “how is this job done differently because I am doing it?” Perspective(远景)plays a huge role in personal satisfaction and sense of well being．Try to remember why you took the job in the first place．

Question：How many aspects does the author give for you to think about to love your job?

Venice’s Carnival

　　Venice, a small, waterside city in northeast Italy, boils with happiness and excitement once every year．Between February 21 and March 4,carnival(狂欢节)hits the streets．For most people, carnival means large parties and feasts(盛宴)．But in Venice, it also means traditional masks(面具)and costumes(服装)．These costumes originally(最初地)meant to hide personal identities(身份)．Different social classes could mix in a sea of happiness．Along the waterways, people greeted each other with：“Good morning, Mrs．Mask．”

　　Today, people in Venice still dress up in the strangest ways－as armed soldiers, butchers, fishermen and so on．Bars and cafés are filled with party-goers who come to show off their fancy(奇异的)costumes．Their designs and creations are made by special studios．Ready-made costumes are not acceptable．“In the months before the carnival we work overtime to meet the demand,” said a mask maker．“Many kilometres of silk and lace(花边)are made into costumes．For shopkeepers, carnival is the best time of the year．”

　　The Venice carnival dates back to the Middle Ages．At that time, the city was one of the wealthiest cities in Europe．The tradition of celebrating with masks and costumes is thought to have been started by the “Stocking Companies”．These were groups of young men who organized parties and festivals and wore colourful stockings to distinguish(区分)themselves．

　　By the 18th century, the carnival had reached its peak(高潮)．It all came to an end when Napoleon conquered(攻取)Venice in 1797．

　　Now the Venice carnival attracts huge crowds from all over the world．This year, about 700 000 people were taking part．Hotels were fully booked in advance, and bars and restaurants overflowed(爆满)every day．

　　The city certainly benefits(得益)．A whole industry has been built up around the carnival’s masks and costumes．“The Venice carnival is a magical(迷人的)time！It’s such a great experience,” said one French tourist．

Question：

Say something about Venice’s carnival in your own words．
