完形填空。     What is a clone? A clone is a copy-a genetic (基因的) copy. Genes (基因) are the in-structions for
life. They    1    a cell what to do and how to do it. Genes make    2    plant or animal different and unique.
A clone has the same genes    3    the original organism (生物体).
      Cloning is not new.    4    have been cloned for centuries. Many new plants are grown from cuttings
(插枝) from the original plants. One benefit of cloning is that we can make many copies of the best and
healthiest plants. 
      It"s     5    more difficult to clone animals than plants. In 1997 scientists succeeded in    6    a sheep.
The creation of Dolly, the Cloned sheep, caused great attention around the world in no time. Scientists had
tried to clone other animals like frogs before that, but they failed Frogs died as tadpoles (蝌蚪), never
living    7    to become adult frogs.
      It may soon be    8    to clone many types of animals. Will we also    9    clone human organs (器官),
or even a whole human being? Maybe now the question is not whether we can clone humans, but   10   
should we clone humans?

        Claude and Louris are "giraffes (长颈鹿)". So are police officers Hankins and Pearson. These men and
women don"t look like giraffes; they look like you and me. Then, why do people call them "giraffes"?
        A giraffe, they say, is an animal that sticks (伸出) its neck out, can see places far away and has a large
heart. It lives a quiet life and moves about in an easy and beautiful way. In the same way, a "giraffe" can be a
person who likes to "stick his or her neck out" for other people, always watches for future happenings, has a
warm heart for people around, and at the same time lives a quiet and beautiful life himself or herself.
         "The Giraffe Project (工程)" is a 10-year-old group which finds and honors (表彰) "giraffes" in the US
and in the world. The group wants to teach people to do something to build a better world. The group members
believe that a person shouldn"t draw his or her head back; instead, they tell people to "stick their neck out" and
help others. Claude and Louris, Hankins and Pearson are only a few of the nearly 1,000 "giraffes" that the group
found and honored.
          Claude and Louris were getting old and they left their work with some money that they saved for future
use. One day, however, they saw a homeless man looking for a place to keep warm and they decided that they
should "stick their neck out" and give him some help. Today, they lived in Friends" House, where they invite
twelve homeless people to stay every night.
          Police officers Hankins and Pearson work in a large city. They see crimes (犯罪)every day and their
work is sometimes dangerous. They work hard for their money. However, these two men put their savings
together and even borrowed money to start an educational (教育的)center to teach young people in a poor part
of the city. Hankins and Pearson are certainly "giraffes".

      "Time is a problem for children," says a news report for a new Swiss watch. Children in some countries
"learn time slowly" because "they don"t wear watches" and "parents don"t really know how to teach them time."
The children grow up with this handicap and become adults and then can"t get to work on time. Is there an
answer to this problem? Of course it"s the Flik Flak, made by a famous Swiss watch company.
      The Flik Flak is being marketed as something teaching watch for children aged 4 to 10. The watch itself
does not teach children how to tell time, of course; it only "takes their imagination" by presenting the "hour"
hand as a beautiful red girl named Flak and the "minute" hand as a tall blue boy named Flik. Flik points to "blue"
minutes on the dial (钟面), while Flak points to "red" hour numbers. The characters and colors together with
parental help, are supposed to teach young children how to tell time. 
      Peter Lipkin, the United States sales manager for the Flik Flak, calls it "childproof: if it gets dirty you can
throw the whole watch in the washing machine," The product is being sold in some department stores in
Europe, Asia and the United Stares for a suggested price of $25. Parents who buy the watch may find that it
is odd thing to tell time; it"s quite another for them to be on time.
1.From the news report we know that _______.
[     ]
A.parents are patient when they are teaching children time
B.parents have little idea of how to teach children time
C.children in every country learn time slowly
D.children enjoy wearing the Flik Flak watch
2.The underlined word "handicap" in the first paragraph means _______.
