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, In1860, 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.
In1961, 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. So far, scientists have 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 to save people from several illness. 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 we learn 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.

The right name is important in the business world. All you have to do is think of the names for some of the products you buy every day and you’ll agree that the name and the product are connected in everyone’s mind.
In many countries, successful trade or brand(商标) names are protected by law so that other companies cannot make the same product by copying. Businesses register(注册) a company or a product name with the government. In fact, more than 1,000 product and company names are registered every hour. Many companies spend a lot of money to find the right name for their products. A good example of this is in the car industry. Some successful names for cars have powerful associations(联系). The Ford Mustang and the Jaguar are only two examples of choosing the names of animals that are fast and strong.
When a U. S company decides to sell its product in another country, it has to make sure that the product name translates(翻译) properly. When Coca-Cola introduced its soft drink to China, it looked for the right name. It wanted a name that would do two things. One was to present its image in Chinese and the second was to be close to its first brand name—Coke. It took some efforts before finding the right word — which sounds similar and translates as “happiness in the mouth”. Asian company names are not new to the United States. The brand names of Samsung and Sony have been successful. Finding the right brand name is a big business. Asian companies that sell to foreign markets pay to find a name that will connect with its customers. There are even naming companies that offer help in inventing product names. These companies can charge up to $100,000 a word for their good names. But it’s worth it. Successful companies know how important the right brand names are for their development.

The food in Britain is very different (1)             our Chinese food. For example，they eat a lot of potatoes. They like to eat them every day. They eat bread for breakfast and usually for one other meal. They eat their bread (2)             butter, maybe cheese or jam, things we don’t eat much in China. Cheese and butter are made from milk. They drink a lot of milk, too. They drink the milk cold or hot, and they put it in their tea. They put sugar in their tea, as well. They are the world’s (3)             (big) tea drinkers. They like Chinese tea, but they drink mostly strong black tea from India and Sri Lanka. They don’t eat much rice. For their main meal they like meat or fish with (4)             (potato)and one or two vegetables. They serve all these together. After the main meal they always have something (5)             . They call this dessert（甜点心）. They don’t have Jiaozi in Britain.

Jack is the name of a game. It is quite popular with children. To play jacks, you will need a small ball and ten small metal objects (物体) called jacks.

  The rules for this game are quite easy. To begin with, put the ten jacks on the floor or ground in front of you. Toss the ball high, pick up one jack and then catch the ball. Keep the jack in your hand and go on to pick up the other jack one at a time. You lose your turn if you do not catch the ball, or if you do not pick up a jack, or if you drop (掉) any of the jacks from your hand.

  When you finish all the ten jacks, you now try to do the same thing again but with two jacks at one time. This is more difficult, of course. You lose your turn if you make any of the above three mistakes (错误) or if you do not pick up two jacks each time.
