As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies．The alike fruit flies are the first insects ever cloned, says the Canadian team that created them．The question everyone asks is why anyone would want to clone flies in the first place．She hopes that the insects, which are very easy to experiment with, will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic(治療的)stem cells．

　　In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(細(xì)胞核)has been removed．At the moment, the majority of cloned mice, sheep and other animals die before birth．It is thought this is because the adult DNA is not properly ‘reprogrammed’．

　　Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals．That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important．If such genes are confirmed, then in theory cloned mammalian embryos(晶胚)might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate．Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful．The team used a slight difference on the standard cloning process： they transferred nuclei taken from embryos rather than fully-grown adult cells．They sucked several nuclei(pl)out of developing fly embryos, and injected them into a fertilized(已受精的)fly egg．From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics．

(1)

The importance of clone

B．

First insects are cloned

the difference of other animals’ genes

B．

the improper technique of clone

(4)

It can be inferred from the last paragraph that ________．

[　　]

A．

the clone of insects before used grown-up cells

B．

the clone of insects were never experimented before

　　Tens of thousands of couples across the United States are racing to get married by April 30．This is the result of a new law that makes illegal(不合法的)immigrants(移民) legal(合法的)if they marry by then．

　　The law has sent marriages rising by 50 percent to 300 percent this year in immigrant-rich Los Angeles, Houston and New York．The new law, passed in the last days of the Clinton administration(任期)，contains a large number of measures to help immigrants and their loved ones become legal．

　　Critics(批評(píng)家)say it also brings many marriage frauds(詐騙)．A key aspect allows immigrants to look for houses while remaining in the USA－if they are married to a citizen or legal resident and hand in applications by April 30．After the date, applicants will have to return to their native countries to deal with their paperwork－a requirement that could take as long as 10 years．

　　Demand for marriage licenses in Manhattan this year jumped from 100 a day to more than 300．The Los Angeles County registrar(戶籍員)recorder's office supplied 12 997 marriage licences during January and February, and 59 percent increase over last year．

　　Critics say the new law encourages false marriage．There are a lot of frauds as people rush to make use of this window．In the past cases citizens or legal residents were paid US ＄10 000 or more to marry illegal immigrants in which immigration is concluded may be investigated for as long as the years after the vows．

　　“It's not worth the risk to attempt an illegal marriage, ”says INS spokesman Bill Strassberger．

(1)

Couples race to get married so that ________．

[　　]

A．

this can show their worship for the God

B．

they can become American citizens

C．

they can find true love there

D．

they can find good places to pray

(2)

If a person misses the deadline(截止日期), he will ________．

[　　]

A．

be put into prison as an illegal immigrant

B．

find a proper job for him to do

C．

be given a good beating by the local police

D．

be forced to go back to his or her homeland

(3)

In the author's eyes, those couples who race to get married are ________．

[　　]

A．

exciting

B．

crazy

C．

disappointing

D．

surprising

(4)

The underlined words“this window” probably refer to ________．

[　　]

A．

B．

C．

the window of the Los Angeles County registrar-recorder's office
