18.How will our continuously growing population affect our way of life,our environment,even our planet?No matter how you look at it,we will face (41)anextremely serious problem.By the middle of the 21st century,we (42)will have used(use) up all the oil that drives our cars if at the rate we're going.Even if scientists develop some new (43)ways(way)of feeding the human race,the crowded conditions on the earth will make (44)Itnecessary for us to look for open space somewhere else.But none of the planets in our solar system are able (45)to support(support) life at present.One possible solution (46)tothe problem,however,has recently been suggested by an American scientist,Professor Carl Sagan.His idea is (47)thatbefore the earth's resources are almost exhausted,it will be (48)totally(total)possible to change the atmosphere of Venus(金星)and so create a new world almost as large as earth itself.
However,(49)beforehis idea is turned into reality,humans have a long way to go.On the one hand,Venus is much (50)hotter(hot)than the earth; on the other hand,there is only a tiny amount of water there.

分析 考查用法填空,文章大意:我们不断增长的人口将如何影响我们的生活方式,我们的环境,甚至我们的星球?有什么解决办法?

解答 41.an,考查冠词,泛指一个严重问题,extremely是以元音开头的,所以用an.
42.will have used,考查将来完成时态.根据时间状语By the middle of the 21st century,应该用将来完成时态.
43.ways,考查名词,way可数名词,前面有some,所以用复数.
44.It,不定式做宾语放在后面,前面需要用it坐形式宾语.
45.to support,考查不定式,be able to do,所以用不定式.
46.to,考查介词,"解决问题的方法"用"the solution to the problem",所以用to.
47.that,考查连词,that引导表语从句,布做成分,没有含义.
48.totally,修饰形容词应该用副词.
49.before,考查连词,根据句意"在她的想法变成现实之前,人类还有很长的路要走",用before.
50.hotter,后面有than,前面需要用比较级.

点评 本题主要考查了用单词或短语的适当形式填空.做本题的关键是在理解短文的基础上,灵活运用所学的基础知识.本题考到的知识点有:固定的短语,词类的转换,名词的复数形式,副词以及祈使句的用法等.因此,这就需要在平时的学习中,牢固掌握各语言点及一些语法知识.

9.Over the last 70 years.researchers have been studying happy and Unhappy people and finally found out ten factors that make a difference.Our feelings of well-being at any moment are determined to a certain degree by genes.However of all the factors,wealth and age are the top two.
Money can buy a degree of happiness.But once you can afford to feed,clothe and house yourself,each extra dollar makes less and less difference.
Researchers find that,on average,wealthier people are happier.But the link between money and happiness is complex.In the past half-century,average income has sharply increased in developed countries,yet happiness levels have remained almost the same.Once your basic needs are met,money only seems to increase happiness if you have more than your friends,neighbors and colleagues.
"Dollars buy Status(社会地位),and status makes people feel better,"conclude some experts,which helps explain why people who can seek status in other ways-scientists or actors,for example-may happily accept relatively poorly-paid jobs.
In a research,Professor Alex Michalos found that the people whose desires-not just for money,but for friends,family,job,health-rose furthest beyond what they already had,tended to be less happy than those who felt a smaller gap(差距).Indeed,the size of the gap predicted happiness about five times better than income alone."The gap measures just blow away the only measures of income,"says Michalos.
Another factor that has to do with happiness is age.Old age may not be so bad."Given all the problems of aging,how could the elderly be more satisfied?"asks Professor Laura Carstensen.
Why are old people happier?Some scientists suggest older people may expect life to be harder and learn to live with it,or they're more realistic about their goals,only setting ones that they know they can achieve.But Carstensen thinks that with time running out,older people have learned to focus on things that make them happy and let go of those that don't.
"People realize not only what they have,but also that what they have cannot-last forever,"she says."A goodbye kiss to a husband or wife at the age of 85,for example,may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20."

6.A simple gesture can be formed into a child's memory so quickly that it will cause the child to give a false answer to a question accompanied by that gesture.A new finding suggests that parents,social workers,psychologists and lawyers should be careful with their hands as well as their words.
While memories of both adults and children are easy to react to suggestion,those of children are known to be particularly influenced,said a researcher,Sara Broaders of Northwestern University.
Previous research,for example,has shown that detailed questions often cause false answers;when asked,say"Did you drink juice at the picnic?",the child is likely to say"yes"even if no juice had been available.It is not that the child is consciously lying,but rather the detail is quickly formed into his or her memory.
To avoid this problem,social workers have long been advised to ask children only open-ended questions,such as"What did you have at the picnic?"But an open-ended question paired with a gesture,is treated like a detailed question.That is,children become likely to answer falsely.
And 77% of children gave at least one piece of false information when a detail was suggested by an ordinary gesture.Gestures may also become more popular when talking with non-fluent language users,such as little kids.Broaders advises parents and other adults to"try to be aware of your hands when questioning a child about an event.Otherwise,you might be getting answers that don't mean what actually happened."

3.Towards the end of Middle English,a sudden change in pronunciation started,with vowels being pronounced shorter and shorter.From the 16th century the British had contact (联系) with people from around the world.This means that many new words and phrases entered the language.The invention of printing also meant that there was a common language in print.Books became cheaper and more people learned to read.Spelling and grammar became fixed,and the dialect (方言) of London became the standard.In 1604,the first English dictionary was published.
The numbers of words in Early Modem English and Late Modem English differ.Late Modem English has a lot more words because of two main factors (因素):firstly,the Industrial Revolution created a need for new words; secondly,the British Empire covered one quarter of the earth's surface,and the English language took in foreign words from many countries.
From around 1600,the English colonization (殖民地化) of North America resulted in the creation of American English.Some English pronunciation and words froze when they reached America.In some ways,American English is more like the English of Shakespeare than modem British English.Some expressions that the British call"Americanisms"are in fact original (原先的) British expressions that were preserved (保存) in the colonies but were lost in Britain.Spanish also had an influence on American English,with words like canyon,ranch,stampede and vigilante being examples of Spanish words that entered English.French words and West African words also influenced American English.
Today,American English is the most influential (影响力的).But there are many other kinds of English around the world,including Australian English,New Zealand English,Canadian English,South African English,Indian English and Caribbean English.They have differences.

53.What can we know from Paragraph 1?B

B.greatly changed
C.a little changed
D.stayed as they were
55.What will the paragraph following this passage most probably discuss?C
A.The development of Modem English
B.How the English vocabulary became larger
C.Differences among the different kinds of English
D.Differences between Middle English and Modem English.
10.Carpooling is when a driver offers to take passengers in exchange for some money for petrol.As (41)a rsult,carpooling can be (42)cheaper (cheap) han public transport because everynoe in the car shares the cost of petrol.I(43)recently (recent) did carpooling for the first time and it was very easy to find a driver.I used a website (44)which/that lists drivers'profiles (简介) and found someone who was going to the same place as me.A lot of information can(45)be seen (see) in the profiles such as their first name,age and gender(性别) as well as reviews from other passengers.I decided (46)to travel (travel) with a lady who had very good reviews.
I found carpooling to be a(n)(47)impressive (impress) experience.Not only was the trip very cheap,but the driver and the other passengers were really friendly.They were all French so I had the chance to practise (48)speaking (speak) some French.When I waved goodbye to them,a thought  suddenly occurred to me (49)that  carpooling could be the future of travel.Both drivers and passengers can benefit (50)from  this form  of travel.It saves money,and perhaps more importantly,carpooling provides a fantastic opportunity to meet interesting people on your travels.
