D

We all accept that sports should stress skill over luck,and fairness over privilege(特权).

They should be accessible to many and fun to watch.In the end,a sport,s champion should re-

present shared values and served as a role model.

But with today,s advances in technology,the power of sports equipment makers offers great

opportunity for the athletes who have access to the latest technology.

In 2008,108 world records were broken in the sport of swimming.The average number of

world records set in swimming in all past Olympic years is about 22.The average number of

world records set in a non-Olympic year is about 5.Now there are no“old”world records.

Suit technology has been the most widely recognized difference.The sharkskin suit and the

“paper”suits were all made public by suit manufactures before the Olympic.

As records continue to be broken,the Internet message boards for the swimming community

have taken a darker view of suit technology.“Time is meaningless”is one quote.I tend to agree.Some of the times I see being posted today are simply legends(传奇).

Am I against suit technology?Not really.But 2008 marked an unbelievable change in the

sport of swimming.People are saying,“Bigger,faster,stronger at any cost!”,wanting no limits on technology,either suits or drugs.I am not one of those people.

I am a guy that recognized the sport of swimming being as simple as man vs.water.It used

to be the swimmer in the suit,not the suit on the swimmer.How times have changed.

53.According to the first paragraph,it is a common belief that________.

A.only a few people have chances to take part in sports

B.the latest suit technology should not be used in sports

C.sports should be interesting for people to watch

D.luck plays an important role in Olympic Games

54.It can be learned from the passage that_______.

A.the author is against the latest technology in sports

B.the athletes have become more skilled than before

C.some records are hard to break without technology

D.advanced suits and drugs can be used in Olympics

55.What does“Time is meaningless”mean in the swimming community?

A.Breaking records in swimming is too easy for most athelets.

B.It,s technology rather than skill that counts in some records.

C.Many athletes break records by luck and taking drugs.

D.Some rules aren,t obeyed when Olympic records are broken.

56.What,s the author,s opinion of the present sports?

A.Latest technology should be encouraged in compitition among athelets.

B.Time should be measured in a different way in modern Olympic Games.

C.All of the athletes should wear the same suits to ensure fairness.

D. Competition in skill should come first instead of that in equipment。
