1、DNA is the whole "map" of the human body. It is something that all humans have,
and it tells the body
what to do. DNA is the reason that we look like our
parents, because we get some of their DNA to make our own.
People have
been trying to understand the human body for a long time. In I860, Mr Mendel
discovered why we look the same as other people in our family. It is because of
small things called "genes"(基因) in
our body. In 1953, two scientists, Watson
and Crick, found out that those small parts are really messages. They're written
in the DNA with a special language.
In 1961, another two scientists found
the first "word" that they could understand in that language. It
shows how
DNA tells the cell (细胞)to build its parts,(有几个单词看不清) the words in the DNA map,
but we still do not understand what they all do. By understanding what just one
"word" means, we can help to save people from several illnesses. So the more we
understand, the more doctors will be able to do.
Most people hope that
this will help to make better medicine and help sick people: Other people worry
that when wc Icam more "words" and find out more information, we will use it in
the wrong way, just to
make people more attractive (有吸引力的), or stop sick
people getting jobs.
2、A famous foreign company in China wanted a clerk for its public relation
department.
A beautiful girl with a master’s degree went through a lot
of challenges and her name was on the list. In
the final stage she faced an
interview together with another girl. Both of them were outstanding, not only
in
looks but also in education.
The girl was successful in the
interview. It seemed that she would get the chance. At last the examiner asked
her, “Can you come to the office next Monday?” Shocked by unexpected question,
the beautiful girl
couldn’t make a decision at the moment. So she said , “I
have to talk with my parents before I give an
answer.” The examiner felt
surprised but said calmly. “If so, let’s wait till you are ready.”
The
next day, the girl came to tell the examiner that her parents had agreed to let
her begin word next Monday. But the examiner said regretfully “Sorry, another
suitable candidate has got the job. You had
better try another place.” The
beautiful girl was surprised. She asked for an explanation and was told,
"What is needed here is a person who knows her own mind.”
That was
how a good opportunity right under the nose of a beautiful girl ran away.
