On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could read the whole “map” of the human body: DNA. DNA is something that everybody has, 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.

People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.

In 1961, Marshall Nirenberg and Johann Matthaci found a message in DNA showing how DNA tells the cell（細胞）to build its parts. Scientists have now found all 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 save more people from several illnesses.

Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn’t limited（限制）in use.

C. The language of DNA.              D. A message of DNA.

(  ) 54. What can we do if we understand some “ words” of the language inside the body

A. Make people get new jobs.           B. Make medicine for illnesses.

Every day in China, about 200 million children go to school. Many of them take school buses. What should we do to keep these students safe on the road?
On April 5, the State Council (國務(wù)院) published new rules about school bus safety. These new rules are much stricter than the old ones.
Under the new rules, local governments must make sure that students attend nearby schools or boarding (寄宿的) schools to reduce traffic risks. Also, local governments must help kids in the countryside reach their school buses.
From now on, school buses have a speed limit of 80km per hour on highways and 60km per hour on normal roads. While on the road, other cars must let school buses go first.
The new rules also say that school buses must never be overloaded (超載的). They have a speed limit of 80 km per hour on highways and 60 km per hour on normal roads.
There are many other rules as well. A school bus must have more than seven seats. On each bus, there must be at least one adult to keep an eye on the kids. Each school bus must have a fire extinguisher (滅火器), a first aid box and a GPS.
Last year, a series of school bus accidents happened in China. To stop such accidents, the Central Government decided to strengthen the rules for school buses.
The most serious accident happened in November in Gansu, when a nine-seat minibus crashed. There were 62 children inside, and 21 of them died.
