6．At one time it was the dream for many little girls to become a nurse．Today，however，America is facing its worst nurse shortage since World War I．Recently about 2，000，000nurses are needed and 60percent of all hospitals in the US have shortages large enough to threaten（=say that you will hurt somebody if they don't do what you want）the quality of care provided．The demand for nurses spreads widely throughout the nursing field．
What has become of these women in white？The answer lies in not one but several causes．One possibility is the fact that woman have greater career options （職業(yè)選擇）．In the past，women who chose to work outside the home had two basic choices：nursing or teaching．Today，more women than ever are in the work force，but their options have greatly increased．There are women doctors，lawyers，firefighters and police officers．In fact，women today are found in nearly every field of work．Nursing has been left behind，as women move on to jobs with higher pay and greater status（地位）．A woman or man in the nursing field is often looked down upon as"merely a nurse"．Teachers may be also at fault．Many high school students are actually being steered（勸 導(dǎo)）away from nursing，told by teachers that they are"too bright to be a nurse"．
Americans are living longer than ever and requiring more medical attention．In fact，the number of elderly patients has almost doubled in the past twenty years．Obviously a larger population requires more nurses．AIDS and other diseases have caused more and more people to need nursing care．Usually fatal diseases mean long drawn-out hospital stay，that is to say，more nurses are needed to care for these patients．It is estimated that the demand for nurses will be doubled the supply in the coming ten years．

21．Why is America facing its worst nurse shortage？C
A．Because the demand of nurses has been doubled．
B．Because more and more women prefer to be teachers and doctors．
C．Because women have been provided with many different jobs．
D．Because women no longer choose to be nurses．
22．The passage tells us that high school teachers are at fault forD．
A．not mentioning the worst nurse shortage in the US
B．introducing jobs with higher pay and greater status to their students
C．not asking the government to raise the nurses'payment
D．persuading the students not to be nurses
23．The author wrote this passage in order toB．
A．describe the unequal treatment of women in the US
B．warn people to pay more attention to the nursing problem
C．tell us women's free choice of jobs today
D．call on women not to be nurses
24．Which of the following is true according to the passage？D
A．high school students think themselves too bright to be nurses．
B．Women in the US have greater career choice than those in other countries．
C．Of all the hospitals in the world 60percent more nurses are badly needed．
D．Nursing used to be a popular job among women．

分析 本文是一篇說明文，介紹對(duì)的是第一次世界大戰(zhàn)后，美國護(hù)士職業(yè)率顯著降低，其中一個(gè)原因是同過去相比，婦女有更多的職業(yè)選擇，并且護(hù)士這一行業(yè)在教育領(lǐng)域受到冷落．然而美國無論現(xiàn)在還是將來，為滿足醫(yī)療領(lǐng)域?qū)ψo(hù)士的大量需求，需要更多的就業(yè)者步入護(hù)士行業(yè)．

解答 21．C．推理判斷題．由第二段one possibility is the fact that woman have greater career options （職業(yè)選擇），其中一個(gè)可能是婦女有越來越多的職業(yè)選擇，C項(xiàng)因?yàn)閶D女被提供許多不同的工作，故選C項(xiàng)．
22．D．細(xì)節(jié)理解題．對(duì)于高校老師的責(zé)任，由文中Teachers may be also at fault．Many high school studentsare actually being steered（勸 導(dǎo)）away from nursing，told by teachers that they are"too bright to be a nurse"．很多高中生事實(shí)上被勸導(dǎo)遠(yuǎn)離護(hù)理，并被老師告知他們很有前途，不能僅僅從事護(hù)士這一行業(yè)，可知，老師在思想上勸導(dǎo)學(xué)生不要去當(dāng)護(hù)士，故選D項(xiàng)．
23．B 推理判斷題．全文講述的是美國的護(hù)士行業(yè)面臨著重大威脅，急需護(hù)士從業(yè)人員，且文章最后也提到未來美國對(duì)護(hù)士就業(yè)人員只會(huì)有增無減，所以可以推導(dǎo)出作者希望就護(hù)士行業(yè)，能引起廣泛注意，選故B項(xiàng)．
24．D．細(xì)節(jié)理解題．At one time it was the dream for many little girls to become a nurse．可知，曾經(jīng)對(duì)于很多小女孩來說，護(hù)士是一個(gè)夢(mèng)想．故選D項(xiàng)．

點(diǎn)評(píng) 本篇文章主旨句即在第一段．因此考生要重視文章的標(biāo)題和文章的首句，因?yàn)槲恼碌臉?biāo)題或首句往往就是文章的主題，有利于考生理解全文內(nèi)容．

18．If it really is what's on the inside that counts，then a lot of thin people might be in trouble．
Some doctors now think that the internal（內(nèi)部的） fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily．
"Being thin doesn't surely mean you are not fat，"said Dr Jimmy Bell at Imperial College．Since 1994，Bell and his team have scanned nearly 800 people with MRI machines to create"fat maps"showing where people store fat．
According to the result，people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat，even if they are slim．
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside．Of the women，as many as 45 percent of those with normal BMI scores （20 to 25）actually had too high levels of internal fat．Among men，the percentage was nearly 60 percent．
According to Bell，people who are fat on the inside are actually on the edge of being fat．They eat too many fatty and sugary foods，but they are not eating enough to be fat．Scientists believe we naturally store fat around the belly first，but at some point，the body may start storing it elsewhere．
Doctors are unsure about the exact dangers of internal fat，but some think it has something to do with heart disease and diabetes（糖尿�。甌hey want to prove that internal fat damages the body's communication systems．
The good news is that internal fat can be easily burned off through exercise or even by improving your diet．"If you want to be healthy，there is no shortcut．Exercise has to be an important part of your lifestyle．"Bell said．
58．What is the passage mainly about？A
A．Thin people may be fat inside．
B．Internal fat is of no importance．
C．Internal fat leads to many diseases．
D．Thin people don't have diabetes．
59．According to the passage，which of the following is WRONG？D
A．Exercise can help to reduce the internal fat．
B．People can get rid of internal fat by improving diet．
C．Men are more likely to have too much internal fat．
D．People with heart disease all have internal fat．
60．From the last paragraph，we can find thatB．
A．internal fat leading to disease has been proved
B．exercise plays an important role in people's life for keeping healthy
C．thin people usually have internal fat even if they are slim
D．it is easier to burn off internal fat than external fat．

1．Man still has a lot to learn about the most powerful and complex part of his body-the brain．
It may be surprising to learn that it isn't age that makes you lose your memory．The reason could be that you have a"lazy"memory，not an old one．Like your body your memory improves with exercise．Once given plenty of exercise，the brain keeps its power．Before discussing how to improve the memory，let's look at how the brain works．There are two sides to the brain，the left and the right．The right side deals with the senses （what we see，hear，feel and smell）．It's the creative and imaginative side．The left side is concerned with logic．It analyzes information and puts it in order．
Some recent research suggests that we remember everything that happens to us．The problem most of us has is recalling events．Most forgetting takes place immediately after learning．An hour after learning something new，more than 50% has been forgotten．After a month，80% has been forgotten，and so on．
This shows revision is very important．If you revise new material you have learnt，you remember much more．So it's of vital importance to revise newly learned material often，and have frequent breaks．We best remember what we learn at the beginning of a learning period and at the point where we stop．After the break，revise what was learned before the break and then continue learning the new material．These breaks should happen every 20 or 45 minutes．
Other experiments have shown the brain needs time to"digest"what has been learned．The time necessary for this is 5 to 10 minutes．After the break，the memory will have absorbed what it has just learned，and more will be remembered．During this period it is important to exercise the right side of the brain，because the left side is used during the learning period．Therefore you should relax．Listening to music，breathing in fresh air，and looking at a picture are all ways of using the other side of the brain．So when you are studying alone，make a plan which shows when to have breaks and to revise newly learned material immediately before you begin studying again．If you do in this way，your memory will improve．

47．According to the text，you lose your memory byB．
A．getting too old                                  
B．hardly using your brain
C．working too hard                                 
D．using your brain too much
48．To fight forgetting effectively，we're advised toA．
A．go back to what was learned regularly
B．break down materials into small pieces
C．focus on both ends of a learning period
D．take breaks to give the brain a good rest
49．During the learning process the brain need breaks toC．
A．use the right side of the brain  
B．revise newly learnt materials
C．take in what has been learnt     
D．relax the left side of the brain
50．Where is this text most probably taken from？D
A．Science fictions．
B．Students'literature．
C．An advertisement．
D．A science report．

11．The emotional bond a child secures with its parents has a greater impact on its education than previously thought，a report suggests．The Sutton Trust study says children's early attachment to parents has far-reaching consequences for their ability to speak，learn and think．Parents who are insecure themselves find it harder to provide children with security，it says．And the report calls for more help so parents can develop such crucial bonds．The study focuses on the application of the theory of attachment-a key theory in child development and psychology．This says the degree to which children are secure and resilient as they grow up depends on their own early experiences with their mothers and fathers and how they have bonded．
The report from the Sutton Trust education charity，entitled Baby Bonds，makes the case that it has an important impact on children's future educational chances as well as their emotional well-being．It is based on an analysis of more than 100studies on the issue，including home visits and assessments and observations of children in a range of countries．The trust argues that although psychologists have been aware of attachment theory，it has not been seen by policy makers as a key influence on educational attainment．And it asks them to take this into account．The report says when babies and toddlers do not form these strong parental bonds-known as secure attachment-they are more likely to exhibit poor language and poor behavior before they reach school．
And it cites international studies which suggest this continues late into life，with insecure children more likely to leave school early or duck out of employment or training．They are also more likely to suffer from aggression，defiance and hyperactivity later in life．
The Sutton Trust says its analysis of the research suggests that about 40% of children in the UK lack a secure attachment with their parents．Lead author Sophie Moullin said that when her team looked at large scale representative studies in a number of countries they all found，from their observations，that between 38% and 42% of children suffered from poor attachment in all the different study locations．She added："Secure attachment really helps children with emotional and social development and at school it really helps them to manage their behavior．Shouting，looking out of the window，hitting each other…These are the things that teachers will tell you that are stopping children from learning．It's really only as we understand more about these behavior problems that we have decided that a lot of it goes back to this early bonding with parents．"
Research director at the trust Conor Ryan said："Better bonding between parents and babies could lead to more social mobility，as there is such a clear link to education，behavior and future employment．The educational divide emerges early in life，with a 19-month school readiness gap between the most and least advantaged children by the age of five．
This report clearly identifies the fundamental role secure attachment could have in narrowing that school readiness gap and improving children's life chances．"More support from health visitors，children's centers together with local authorities in helping parents improve how they bond with young children could play a role in narrowing the education gap．"

The Sutton Trust study
IntroductionThe study reveals children's early attachment to parents （71）largely/greatly affects their ability to speak，learn and think．
Method of the studyResearchers （72）analyzed/analysed more than 100case studies on the issue through visiting homes，assessing children and （73）observingchildren．
Statistics of the study•In the UK，only about 60% of children have a secure attachment with their parents．

•In other countries where the studies were carried out，the numbers are quite （74）close．
Negative effects of insecure （75）attachment•A （76）lack of secure parental bonding may lead to poor language and behavior for preschool children．
At the age of five，the （77）biggest school readiness gap between children can be 19months．

•Without secure attachment，future life difficulties such as quitting school，（78）hiding/escaping from work and other emotional issues would emerge．
The significance of parental attachmentBetter bonding between parents and babies could lead to a change in people's social （79）status because it narrows children's school readiness gap and it improves children's life chances．
SuggestionA （80）combined/joint effort is needed for strong parent-child bonding．
