1.Intel chairman Andy Grove has decided to cut the Gordian knot of the dispute on stem cell (干细胞) research by simply writing a check.The check,which he guaranteed last week,could be for as much as 55million,depending on how many donors make gifts of between 550,000and 5,500,000,which he has promised to match.It will be made out to the University'of California-San Francisco (UCSF).
Thanks in part to such private donations,university research into uses for human stem cells,the cells at the earliest stages of development that can form any body part,will continue in California.With private financial support,the state will be less likely to lose talented scientists who would be tempted to leave the field or even leave the country as research dependent on federal (联邦政府的)money slows to glacial (极慢的) pace.
Held back by limits President Bush placed on stem cell research a year ago,scientists are turning to labs that can carry out work without using federal money.This is awkward for universities,which must spend extra money building separate labs and keeping strict records proving no federal funds were involved.Grove's donation,a first step toward a﹩20million target at UCSF,will relieve the burden.
The president's decision a year ago to allow research on already existing stem cell lines was portrayed as a reasonable compromise (折中办法) between scientists'needs for cells to work with,and concerns that this kind of research could lead to wholesale creation and destruction of human embryos (胚胎),cloned infants and a general disrespect for human life.
But Bush's effort to please both sides ended up pleasing neither.And it certainly didn't provide the basis for cutting edge research.Of the 78existing stem cell lines which Bush said are all that science would ever need,only one is in this country (at the University of Wisconsin) and only five are ready for distribution to researchers.All were grown in conjunction with mouse cells,making future therapeutic ( 治疗的 ) uses unlikely.
The Bush administration seems bent on satisfying the small but vocal (直言不讳的) group of Americans who oppose stem cell research under any conditions.Fortunately,Groye and others are more interested in advancing scientific research that could benefit the large number of Americans who suffer from Parkinson's disease,nerve injuries,heart diseases and many other problems.

72.When Andy Grove decided to"cut the Gordian knot",he meant toC.
A.put an end to stem cell research
B.end Intel's relations with Gordian
C.settle the argument on stem cell research
D.prohibit Gordian from doing stem cell research
73.According to Bush's decision,American universities had toD.
A.conduct the research in labs overseas
B.abandon the research altogether
C.carry out the research secretly
D.raise money to build separate labs
74.We may infer from the passage that future therapeutic uses of stem cells will be unlikely unlessA.
A.human stem cells are used in the research
B.a lot more private donations can be secured
C.more federal money is used for the research
D.talented scientists are involved in the research
75.The reason why Bush placed limits on stem cell research was thatB.
A.his administration was financially limited
B.he did not want to offend its opponents
C.it might lead to a disrespect for human life
D.it did not promise any therapeutic value.

16.Have you ever wondered why our Easter celebrations include bunnies,brightly colored eggs,baskets filled with bite-size candy,and a banquet of ham or lamb?In fact,most of our Easter traditions are rooted in Christian faith and early religions.Here's a brief history lesson on customs.
Easter Bunny(复活节兔子)
The Easter Bunny-a.k.a Osterhase(German)or Oschter Haws(Dutch)-made its U.S.debut when German and Dutch settlers arrived in colonial Pennsylvania villages during the1700s.Pre-Christian Germans honored an Anglo-Saxon goddess,Eostre,who represented the rising of a new sun season.It's believed that she had a hare as a companion that represented fertility(生育力)and rebirth.
Easter Basket
Similar to the meaning of leaving cookies for Santa on Christmas Eve,children would leave homemade nests in which the Easter Bunny could lay its colored eggs.Over time,this tradition turned into decorated Easter baskets filled with fake grass,chocolate candy and jellybcans.
Easter Eggs
Christians(基督徒)don't eat meat and eggs for 40days in preparation for spiritual update.On Easter Sunday,red colored eggs decorated tables to promote the joy of a new season and represent Jesus'blood on the cross.The colored egg tradition may also have roots in spring festivals,in which eggs were decorated,colored and exchanged as celebrations of spring.
Ham
You know block-eyed peas bring luck on New Year's Day,but what if we told you a pig had much the same effect?The pig was considered a symbol of luck in pre-Christian Europe,and early Christians were said to have continued this tradition,making it the centre of meals on significant holidays like Christmas and Easter.
If we took a poll on eating ham or lamb on Easter,we'd likely be a country divided.

21.What does the passage mainly focus on?C
A.Easter presents.    
B.Easter beliefs.
C.Easter customs.
D.Easter food.
22.Why do people exchange colored eggs on Easter Festival?A
A.To welcome the coming of spring.
B.To attract visitors.
C,To decorate tables.
D.To invite Santa Claus.
23.What did"the pig"represent in pre-Christian Europe?B

6.All parents know that one of their most important tasks is to prepare their children for an independent life,but any parent can tell you that it's hard to let go of your children.That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking.Years of experience means that parents often do know best,but on the other hand,the young,being less bound by tradition,are often more creative,more able to find new solutions to old problems.Revolutions are led by the young.
Good teachers make the growth of critical (批判性的) thinking easier in their students,only to find that this can lead to a questioning of the teachers'basic beliefs.Schools encourage parents to become involved,but are often embarrassed when parents have reservations about some of the educational methods being used.Governments encourage unimportant groups to empower themselves in order to participate fully in the development process.And they are often surprised when the new leaders of these groups turn around and attack the policies of that same government.The rebellions (叛逆的)young and the newly unimportant groups are important in social development.They are not necessarily representatives of those   they want to represent or not realistic in their demands,but their voices must be heard.
Good parents know that just forbidding particular behaviors does not prevent their children from finding ways to engage in these forbidden activities.Indeed,sometimes the forbidden fruit is more inviting,just because it is not accepted by authority.Parents must work with their children to educate them on the facts,know as much as possible about the lives of their children,provide a good example,encourage more wholesome activities but also support their children when they don't follow what is expected of them.But the most important point is that they also need to learn how to let go.

13.Tips for avoiding traffic jams
The radio has more than just music.Check the local news station for the latest traffic report.Or go online and check traffic cameras before you set out.If there is a jam,you'll be prepared and can try another route.
Take the road less traveled.Although highways may be the most direct route,back roads can be much less crowded,which can save you from the frustration of the stop-and-go traffic.
Rush hour isn't just a lovely nickname.It means the morning and afternoon traffic lasts for several hours,but they are still called"rush hour"for a reason-everyone's on the road and in a hurry to get somewhere.Treat rush hour like bad weather-if you don't have to go anywhere,stay off the roads.
Tips for those unavoidable traffic jams
Don't break the law.You've gone 30feet in 30minutes and all of a sudden you see people using the shoulders(紧急停车道).Don't behave like them.Not only is this illegal,but also there's a good chance they'll get caught or cause even more problems.
Pay extra attention to zig-zaggers when some people are anxious,they may start changing lanes every 5seconds or cut you off.Keep checking your windows and mirrors for these lane changers.
Look for an escape.If it is possible to exit the road safely,do it.Use a GPS unit,and you can change your route mid-trip if needed.
Be courteous.Good manners could help you avoid a possible accident.Allow people in from a lane that is ending.Speeding up to keep them out increases your chances of an accident.
60.To avoid traffic jams,we are advised to do the following EXCEPTD.
A.get traffic news before leaving
B.choose back roads
C.avoid rush hours
D.change lanes frequently
61.What should we do when there are zig-zaggars?A
A.Keep checking the mirrors
B.Stop and let them go first.
C.Sound the horn loudly
D.Drive quickly to keep them out.
62.When there is a traffic jam,we shouldC.
A.get off the car and walk round
B.use the shoulders as lanes
C.change the route if possible
D.drive back immediately
63.What do the underlined word"courteous"in the last paragraph mean?B
A.energetic
B.polite
C.careful

11.All work and no play makes Jack a dull boy.That saying holds true not only for you and me,but also for some of the most powerful and influential people in the world,such as the presidents of the United States.
But how do American presidents spend their vacation time?Let's take a look!
Franklin D.Roosevelt,considered one of the greatest presidents in American history,had limited vacation options because of his polio(小儿麻痹症).He began visiting Warm Springs,Georgia in 1924 for its curative waters and later built a 2,000 acre polio treatment center nearby.He liked to cruise the Potomacon his yacht(游艇) and three times as president returned to his beloved Canadian island of Campobello,with which he fell in love as a kid.
Former President Bill Clinton,however,was never much good at vacationing.His staff had to practically force him to go on vacation his first year in office; his idea of relaxing was reading four good books simultaneously(同时) while enjoying a cigar (chewed,not smoked).He could also lose himself in a game of golf,where his somewhat flexible interpretation of the rules could at times drive his partners crazy.
Obama's predecessor(前任) also knows how to relax.Fishing is in the Bush family DNA:for blue sharks off the coast of Maine or anything with fins,almost anywhere else.George W.Bush also relaxed as president by jogging and clearing brush on his Texas ranch.Since leaving office,he has become an active mountain biker and,more recently,has taken up painting.
Obama tends to take a winter break in Hawaii,where he was born and raised,and a summer vacation in Martha's Vineyard,off the southern coast of Cape Cod,Massachusetts.In between,he plays basketball every couple of weeks and has been known to do some skeet shooting at Camp David.Obama's favorite pastime,no matter the location,has become easy to spot:golf.
71.What's the passage mainly about?A
A.US presidents on holiday
B.Relationship between work and play.
C.Famous US presidents
D.Suggestions on spending holidays.
72.What's the main reason for Franklin choose to spend his holidays in the spring or on his yacht?B
A.Personal interests
B.Physical disability.
C.Tidal current
D.Official arrangement.
73.What's special when Bill Clinton was playing golf?C
A.He could often be the top player
B.He could often be the bottom player.
C.He did not often respect the rules
D.He usually showed good team spirit.
74.From Paragraph 5,we may infer thatD.
A.the Bush family were mostly fishermen.
B.the Bush family like to fish only near Maine.
C.father of George W.Bush likes to work on farm.
D.father of George W.Bush also loves fishing.
75.In the last paragraph,many of Obama's hobbies are mentioned EXCEPTA.
