Cloning（克隆）:Future Pertect?

1 A clone is an exact copy of a plant or animal produced from any one cell.Since Scottish
scientists reported that they had managed to clone a sheep named Dolly in 1997,research
into cloning has grown rapidly.In May 1998,scientists in Massachusetts managed to
create two identical calves（牛犊）using cloning technology. A mouse has also been
cloned successfully.But the debate over cloning humans really started when Chicago
physicist Richard Seed made a surprising announcement:"We will have managed to clonen
a human being within the next two years."he told the world.
2 Seed's announcement provoked a lot of media attention,most of it negative.In Europe,
nineteen nations have already signed an agreement banning human cloning and in the U.S.
the President announced:"We will be introducing a law to ban all human cloning and many
states in the U.S. will have passed anti-cloning laws by the end of the year."
3 Many researchers are not so negative about cloning.They are worried that laws banning
human cloning will threaten important research.In March,The New England
Joumal of
Medicine called any plan to ban research on cloning humans seriously mistaken.Many
researchers also believe that in spite of attempts to ban it,human cloning will have become
routine by 2010 because it is impossible to stop the progress of science.
4 Is there reason to fear that cloning will lead to a nightmare world?The public has been
bombarded（轰炸）with newspaper articles , television shows and films , as well as
cartoons.Such information is often misleading,and makes people wonder what on earth
the scientists will be doing next.
5 Within the next five to ten years scientists will probably have found a way of cioning
humans.It could be that pretty soon we will be able to choose the person that we want our
child to look like.But how would it feel to be a clone among hundreds,the anti-cloners
ask. Pretty cool , answer the pro-cloners（赞成克隆的人）.

Within ten years scientists will probably have______.
A:the nucleus of a cell
B:cloned human beings
C:a human being in two years
D:a law to ban human cloning
E:a report on human cloning
F:heavy media coverage

Mad Scientist Stereotype Outdated

Do people still imagine a physicist as a bearded man in glasses or has the image of the
mad scientist changed?The Institute of Physics set out to find out whether the stereotype of
a physics"boffin"（科学家）still exists by conducting a survey on shoppers in London. The
people were asked to identify the physicist from a photograph of a line-up of possible
suspects.98 percent of those asked got it wrong.The majority of people picked a white
male of around 60,wearing glasses and with a white beard.
While this stereotype may have been the image of an average physicist fifty years ago,
the reality is now very different. Since 1 960 the number of young women entering physics
has doubled and the average age of a physicist is now 31.
The stereotype of the absent-minded scientist has lasted a long time because the media
and Hollywood help promote the image of men in white lab coats with glasses sitting by
blackboards full of equations（等式）or working with fizzing（嘶嘶响）test tubes. These
stereotypes are really damaging to society.Very good school children are put off studying
science because they don't see people like themselves on television or in magazines doing
science.They simply don't relate to the media's image of the mad scientist.
This is one reason why fewer young people are choosing to do science at university.If
we want to encourage more young people to study science subjects,we need to change
this image of the scientist and make science careers more attractive.But we must also
develop children's interest in science.
In an attempt to change this negative image,an increasing number of science festivals
are being organized.Thousands of people from secondary schools are also encouraged to
take part in nationwide science competitions of which the most popular are the national
science Olympiads.Winning national teams then get the opportunity to take part in the
International Science Olympiads which are held in a different country every year.These
events are all interesting for the young people who take part but they only involve a small
proportion of students who are already interested in science.It seems that there is a long
way to go before science becomes attractive as subjects like computer studies or fashion
and design.

Most people have similar ideas of what a physicist looks like.
A:Right
B:Wrong
C:Not mentioned

He must use this surplus in three ways:as seed for sowing,as an insurance（ ）the unpredictable effects of bad weather and as a commodity which he must sell in order to replace old agricultural implements and obtain chemical fertilizers to feed the soil.

A.for
B.against
C.of
D.towards
