	A．	has been increasing； are		B．	have increased； is
	C．	has been increased； is		D．	had increased； are

分析中国私家车的数量自从2005年以来一直在增长，但是只有15%的是中国制造．

解答答案是A．本题考查现在完成进行时．题干中"since 2005"是与现在相联系的段时间，是现在完成时的标志，故排除D；现在完成进行时表示表示从过去某时开始到现在这一段时间里一直延续着的动作还在继续进行；根据语境和常识判断，中国私家车数量的增长还在进行中，故选A．此外关注第一空的主语是"the number of+复数名词"，表示"…的数量"，谓语动词用单数；第二空句的主语是15%of them，是复数概念，谓语动词用复数．

点评完成进行时的解题首先要理解其时态的基本用法--表示从过去某时开始到现在这一段时间里一直延续着的动作，特别关注其"在进行中"的特征；然后在语境中寻找动作的时间依据进行判断．

5．Heavy downpours last month in Rhode Island led to widespread flooding，causing millions of dollars in property damage and leaving thousands homeless．The flood waters also poured vast amounts of raw sewage（未经净化的污水） into the rivers and streams that flow into Narragansett Bay．
It sounds like the makings of an environmental nightmare．But in fact it's just the opposite．To scientists'delight．The sewage-loaded floodwaters have caused a well-timed growth of phytoplankton．The microscopic creatures that form the foundation of marine（海洋的） food chains．With more food available for fish．Clams and other sea creatures．The bay's fisheries industry is expected to benefit．
In decades past．Narragansett Bay typically experienced a late winter early spring algal（海藻） bloom that fed creatures up and down the water column．But in recent years，the waters of Narragansen Bay warmed greatly，meriting this seasonal event．
Mark Berman，an oceanographer with the Nationa．Marine Fishertes Service．Said the flood seemed to have sent the bay back in its normal state．
However，local，mutate and federal officials in Rhode Island leave been batting other algal blooms that，by contrast，are causing widespread harm to the Narragansett Bay ecosystem．During summer months，sewage and agricultural runnel flows into the bay．Causing large blooms．But inseam of becoming food for sea creatures，much of the phytoplankton is consumed by bacteria，which grow last in the warmer waters．The rapid bacteria growth leads to hypoxia decrease of oxygen in the water that can cause large fish tools．One such die-off occurred in 2003．when millions of oxygen-starved fish washed up on the belches of Narragansett Bay．
The flood's positive impact will probably be a one-time event，Mr Berman said．Mcanwhile efforts to   curb  the harmful summer honors continue； in 2003．for instance，Providence completed a﹩359million sewage tonal under the city designated to reduce the polluted storm overflow into Narragansett Bay．

6．A recent survey has shown that the number of people in the United Kingdom who do not intend to get internet access has risen．These people，who are known as'net refuseniks'，make up 44% of UK households，or 11.2million people in total．
The research also showed that more than 70percent of these people said that they were not interested in getting connected to the internet．This number has risen from just over 50% in 2005，with most giving lack of computer skills as a reason for not getting internet access，though some also said it was because of the cost．

3．For many people around the world，a subway journey means speeding from one dull station to the next，surrounded by too many uncomfortable，impatient people．But on the Moscow Metro，taking the subway is like walking through a national heritage site．Depending on where you get off，you'll receive a brief course in architectural movements and face colorful glass windows，marble（大理石）columns，gilded （鎏金的）mosaics and painted scenes from Russian history．
"These extraordinarily beautiful places are unlike any metro station I've ever seen，"says Vancouver-based photographer David Burdeny．
When Burdeny，who himself has a master's degree in architecture，first found out about Moscow's metro stations，he was struck by the work of art．In all，he has photographed 20of the most beautiful stations．
Burdeny had originally planned to focus on Russian stations more generally，taking photos of examples in both St．Petersburg and Moscow．
"But when I saw the stations in Moscow，they just completely blew away the St．Petersburg ones，"he says．
Shooting in the subway sounds simple，but it is not without challenges．For one thing，Burdeny had to figure out a way to access them between 12：30a．m．and 5：30a．m．，when the stations were closed．
In the end，he settled on Arbatskaya Metro Station，whose vaulted （拱顶的） arches he found the most beautiful．But it also represented a challenge he was not sure he was able to overcome：conveying the hugeness of the spaces．The Arbatskaya platform，for example，stretches 820feet．"Some of the arches are quite long，"he says．"When you enter them，they're just so completely grand．"
1．We can learn from the text that David BurdenyD．
A．is a world-famous architect
B．is studying Russian history
C．took the subway to and from work
D．took photos of Moscow subway stations
2．What Burdeny found challenging wasC．
A．when to take photos of Moscow subway stations
B．whether to work in St．Petersburg or Moscow
C．how to photograph the long arches at Arbatskaya Station
D．where to get off to study the Moscow metro system
3．What does the underlined word"shooting"mean in Paragraph 6？B
A．Firing bullets from a gun．
B．Taking photographs．
C．Making movies．
D．Throwing the ball at the basket．

18．Does money buy happiness？Not!Ah，but would a little more money make us a little happier？Many of us smirk（傻笑，假笑） and nod．There is，we believe，some connection between financial fitness and emotional fulfillment．Three in four American college students-nearly double the 1970 proportion-now consider it"very important"or"essential"that they become"very well off financially"．Money matters．
But a surprising fact of life is that in countries where nearly everyone can afford life's necessities，increasing wealth matters surprisingly little．The connection between income and happiness is"surprisingly weak，"observed University of Michigan researcher Ronald Inglehart in one 16-nation study of 170，000people．Once comfortable，more money provides diminishing returns（报酬递减）．The second piece of pie，or the second﹩100，000，never tastes as good as the first．Even lottery winners and the Forbes'100 wealthiest Americans surveyed by University of Illinois psychologist Ed Diener have expressed only slightly greater happiness than the average American．Making it big brings temporary joy．But in the long run wealth is like health：its complete absence can create suffering，but having it doesn't guarantee happiness．Happiness seems less a matter of getting what we want than of wanting what we have．
Has our happiness，however，floated upward with the rising economic tide？Are we happier today than in 1940s，when two out of five homes lacked a shower or tub？Actually，we are not．Since 1957，the number of Americans who say they are"very happy"has declined from 35 to 32 percent．Meanwhile，the divorce rate has doubled，the teen suicide（自杀） rate has increased nearly three times，the violent crime rate has gone up nearly four times，and depression has mushroomed．Economic growth has provided no boost to human morale．When it comes to psychological well being，it is not the economy．
I call this soaring wealth and shrinking spirit"the American paradox．"More than ever，we have big houses and broken homes，high incomes and low confidence，secured rights and reduced civility．We are good at making a living but often fail at making a life．We celebrate our prosperity（繁荣） but long for a purpose．We treasure our freedoms but long for connection．In an age of plenty，we feel spiritual hunger．

63．Which of the following statements best expresses the author's view？C
A．The more money we earn，the less returns we have．
B．The more money we earn，the happier we would be．
C．In the long run，money cannot guarantee happiness．
D．In the long run，happiness grows with economy．
64．"The second﹩100，000 never tastes as good as the first"becauseD．
A．it is not so fresh as the first﹩100，000
B．it is not so important as the first﹩100，000
C．profit brought by it is less than that from the first﹩100，000
D．happiness brought by it is less than that from the first﹩100，000

A．have any primary aim
B．know how to spend money
C．know how to enjoy life
D．keep in touch with other people
66．The things that happened after 1957are given to show thatA．
A．people's spiritual needs cannot be fulfilled by wealth
B．family problems become more and more serious
