6．Many of the world's countries have reached or are approaching zero population growth （ZPG）．Nearly all such lands are economically well developed．They include much of Europe（including Russia），the United States，Canada，Japan．a(chǎn)nd Australia．As the rate of natural increase（RNI）declines（下降），two things happen．First，the population begins to decline if the loss is not balanced by immigration（移民）．Second，a country's population ages because there are fewer births．
Is achieving ZPG good or bad？What happens when a country's population begins to drop？Many people，after all，believe that population decline is a good thing．But is it good for everyone？Does everyone agree？
An aging population can create many problems．Senior citizens require more health care and medical attention．Rather than paying into retirement programs，they begin to draw from their pensions（退休金）．In the US，the Social Security program，according to many experts，will be used up by 2018．It will pay out more money than it takes in．Additionally，a great number of jobs go begging in search of people willing or entry level positions that pay low wages．With an ability to do them many of these jobs are aging population，who will fill them？At the other extreme，some positions require a large number of training and highly specialized skills．Who will fill these positions as retirees leave the workforce？
The answer to the problem of declining and aging population is simple：increased migration（移居）．
Today many people，particularly those from less developed countries，are migrating in search of employment．Many are willing to take jobs that cannot（or will not） be filled bythe domestic（國內(nèi)的） population．Others are well educated and highly skilled．Both groups contribute to a country's economy progress in many ways．Further，they add to the richness of a country's culture．Of greatest importance，perhaps，is the fact that they have become absolutely（完全地）necessary to the economy of many lands．As you can see，for many countries and for most immigrants，migration is a win-win situation．

29．In the writer's view，which of the following statements is TRUEA？
A．Not everyone agrees that achieving ZPG is absolutely good
B．Achieving ZPG is every country's aim（目標(biāo)） in spite of its side effects
C．Achieving ZPG is bad for senior citizens
D．Achieving ZPG is good for employment
30．According to the passage，the best way to solve the problem of declining and aging population isD．
A．to improve the health care system
B．to increase RNI
C．to increase employment               
D．to increase migration
31．The main idea of the last paragraph isA．
A．the advantages of increased migration
B．the problem of declining and aging population
C．how to increase migration
D．some ways to enrich a country's culture．

分析 本文是一篇科教類閱讀，主要講述了一個人口零增長的社會現(xiàn)象．在很多國家，尤其是一些發(fā)達(dá)國家，人口呈現(xiàn)零增長或者負(fù)增長的現(xiàn)象．但是這種現(xiàn)象并不是只有好處的，它帶來的危害也很多．所以移民可以帶來雙贏的作用．

解答 29．答案：A．細(xì)節(jié)理解題．文中第三段說 An aging population can create many problems．人口老齡化的問題嚴(yán)重，人口零增長會造成人口老齡化的，所以A選項表述正確，故選A．
30．答案：D．細(xì)節(jié)理解題．根據(jù)"The answer to the problem of declining and aging population is simple：increased migration"可知，最好的解決方法是增加移民．故選D．

14．Dear Ms．Wang，
  I am writing to inform you of some arrangements about my composition course and Latin course next year．
  I've decided to re-establish the 5-paragraph essay as the goal for the composition course．I interviewed some of my former students and they all agreed that being able to write critically and continuously was important to them．
  So next academic year，Term 1 will be like always：sentences to paragraphing．And Term 2 will work toward the 5-paragraph essay．The final 3 weeks of Term 2 will be reserved to introduce writing for TOEFL and CEE．By that time，if the students have done their job correctly，then they should be able to write quite well．
  As for the Latin course，I will post notices around campus next week so that the students will understand what's on offer before I actually introduce the course．A number of students already emailed me about the course．
  I am sure you don't understand what a big deal our opening this program at our school is．People around the world are interested in what we plan to do．There are many rewards available to the students who succeed in the course．Please share what I have sai d with the administration．I want them to understand the importance of this course．The reason I have contacted these colleagues （actually Oxford contacted me） is that I have confidence in our students and in myself．I know that when those professors meet our students and hear them speaking and reading Latin，they are going to be amazed．It will open all sorts of doors for students that they never even thought of knocking on．
  Well，that's it for now．I'll see you soon．

People have strange ideas about food．For example，the tomato is a kind of very delicious vegetable．It is one of useful plants that can be prepared in many ways．It has rich nutrition and vitamin in it．But in the 18th century，Americans never ate tomatoes．They grew them in their gardens because tomato plants are so pretty．But they thought the vegetable was poisonous （有毒的）．They called tomatoes"poison apples．"

11．March 21has been declared World Sleep Day，a time to recognize and celebrate the value of sleep．Many sleep experts hope it will be a wake-up call．
According to a poll （民意調(diào)查）by the National Sleep Foundation，nearly 4in 5Americans don't get as much sleep as they should during the workweek．On average，adults are thought to need at least eight hours of sleep a night，although some can manage with less and some won't do well without more．But the survey found that，on workdays，only 21% of Americans actually get a full eight hours of sleep，and another 21% get less than six．
To many of us，the thought of spending more time sleeping is，well，a big yawn．On the other hand，the thought of being smarter，thinner，healthier and more cheerful has a certain appeal．And those are just a few of the advantages that can be ours if we consistently get enough sleep，researchers say．Also on the plus side：We're likely to have better skin，better memories，better judgment，and，oh，yes，longer lives．
"When you lose even one hour of sleep for any reason，it influences your performance the next day，"says Dr．Alon Avidan，director of the UCLA Sleep Disorders Center．
A study published last year found the same to be true even of children．When kids aged 8to 12slept for just one hour less for four nights，they didn't function as well during the day．
But sleeping has an image problem．"We see napping or sleeping as lazy，"says Jennifer Vriend，a clinical psychologist in Ottawa，Canada，and the leading author of the study with children．"We put so much emphasis on diet，nutrition and exercise．Sleep is in the back seat．"In fact，she adds，no matter how much we work out，no matter how well we eat，we can't be in top physical shape unless we also get plenty of sleep．

21．The underlined part in Paragraph 1meansB．
A．to wake up the sleepers
B．to draw people's attention
C．to serve as a morning call
D．to declare the special day
22．From Paragraph 3we can infer thatD．
A．being healthier is one of the advantages for us
B．sleeping has nothing to do with one's expectations
C．spending more time on sleeping is a waste of time
D．enough sleep is the guarantee of the appealing things
23．What Jennifer Vriend said in the last paragraph implies thatB．
A．sleeping is an image problem
B．people care little about sleeping
C．lazy people tend to sleep long
D．sleeping is only part of our life
24．What is the purpose of the passage？C
A．to talk about people's sleeping problems．
B．to provide an investigation result of sleeping．
C．to arouse the awareness of enough sleeping．
D．to stress the function of sleeping at night．

15．閱讀下面短文，根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要．
Punishing children is a controversial topic．Everybody has different opinions about how to act to correct a child's behavior．Parents，teachers，doctors and specialists such as psychologists，have disagreements about whether it is good for a child's education to punish him or her．
The word"punish"means different things to different people．Punishment can be physical or emotional．Physical punishment is when the parent hits，slaps or spanks the child．
On the other hand，emotional punishment is when the parent，in order to educate the child，doesn't let him or her watch TV，go to play with his or her friends，or do things like that．The parent doesn't teach him or her，but still he or she punishes the child．
Although many surveys and studies have been made about what the correct way is to raise a child，nobody has the answer or the truth．I think it will be very difficult to find the answer or get people to agree．
I think the parents should love their child and give him or her the best education，but at the same time，they should punish the child if he or she deserves it．I think if you love your child，you should be rational when you apply the punishment．It should be reasonable but strict．
The parents'goal is to have in the future a good man or woman in society，so sometimes you should do what is necessary to get your child to behave well．
