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(细胞)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.

Nobody is happy all the time, but some people are really happier than others. Here are some tips for you to be happy.
Make enough money to meet your basic needs: food, shelter, and clothing. In the US, that magic number is $40,000 a year. Any money you make beyond that will not necessarily make you happier. Once you make enough money to support your basic needs, your happiness is not affected by how much money you make.
______________________________ Or move to where other members are-so you can see them more. Now, people follow jobs around the country and sometimes around the world. As a result, our relationships with our friends and family have a far greater impact (影响) on our happiness than our jobs do. So next time you think about moving, consider a place where most of your friends and families live.
Find happiness in the job you have now. Many people expect (期待) the right job to change their level of happiness. But happiness research makes it clear that changing jobs can’t bring you happiness. If you want, you will make the best of any job. If you have good relationships with people, you won’t depend on (依赖) your job to give your life a greater sense of meaning. You will find it in your interactions with the people you care about.
If you are unhappy for a long time, you should ask an expert (专家) or a doctor for help. I hope you will be happy all the time.

New York is a very large city with 8 million people. How do so many people move about the city on their way to work and school? So, we should know something about its transportation.
In New York you can travel about the city by subway, bus, taxi and car. The subway runs on the railroad lines under the city. It crosses the city at different points and goes all parts of the city. Traveling by subway is the fastest way to get around the city.
The second way to travel around the city is by public bus. It’s a slower way to travel. This is because the bus moves in road traffic which is often heavy.
You can also travel around the city by taxi. This is the most expensive way, but the taxi will take you to the very place you wish to go to. If traffic is heavy, the taxi will be slow. During the mornings and afternoons, this is the “rush hour”. This is the time when the traffic is very heavy with people going to and from work.
The last way to get around New York is using your own car. However(但是), it’s not easy for you to drive, especially(尤其是)when you are driving in the “rush hour”. If there is an accident(交通事故)on the road, you will have to wait for a long time.
The best time to travel around the city is from 9am to 4 pm. This is the time after the morning “rush hour” and before the evening “rush hour”. Traffic will be less crowded because most people are already at school or at work.
