题目内容

【题目】阅读下列短文,从每小题所给的A、B、C、D四个选项中选出一个最佳选项。
It takes a lot of skills and hard work to set a world record in pumpkin-carving(雕刻南瓜). Steve Clarke, a sixth-grade teacher from Pennsylvania, is a famous carver(雕刻师). Clarke has set many world records for carving pumpkins quickly. When he competes, he must cut our two eyes, two eyebrows, a nose, a mouth, and two ears as fast as possible. But Clarke knows something else about pumpkin-carving. It's easier to get a record than to keep it.
He took the title in 2000 when he carved a pumpkin face in 74.8 seconds. That time was 19 seconds faster than what Jerry had set. From then on, Clarke broke his own records five times. In 2006, he set his best time in Florida. His winning time was 24.03 seconds!
The only problem is that someone finally beat that mark. On October 7, 2010, David set the new record with 20.1 seconds. Clarke was not able to break that record this year, but he has planned to break the record. After Halloween, he will go to local pumpkin farms to practise designs and new skills.
Clarke is popular because of his super pumpkin-carving skills. In 1999, he carved more than 30 pumpkins at the Halloween party for then vice-president Al Gore.

On June 26th, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own. Now we can read some of this “map”, and so we can find out more about how our bodies work.
People have been trying to understand the human body for a long time. In 1860, Gregory Mendel discovered that there is a special reason why we look the same as other people in our family. It is because of small things called “genes” that we have in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are really messages written in the DNA with a special language.
In 1961, Marshall Nirenberg and Johann Matthaei found the first “word” that they could understand in that language, showing how DNA tells the cell to build its parts. This meant that one day we would be able to read all the messages that a human body gets from its parents' bodies. Scientists have now found all the words in DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save people from several diseases. 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 people who are very ill. Other people worry about that when we learn more words and find out lots of other information, we still use it in the wrong way, just to make people more attractive, or stop sick people getting jobs.
(1)Could Francis and Craig read the “map” of DNA in 2000?
(2)Why do we look like our parents?
(3)When was the first “word” of DNA discovered?
(4)What can the doctors do if we understand some messages in DNA?
(5)What does the writer tell us in the last paragraph?
