On June 26, 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 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 Matthaei 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 technology (技术) wasn’t limited (限制) in use. When did we first know why we look like other people in our family?
| A．In 1860. | B．In 1953. | C．In 1961. | D．In 2000. |
What did the two scientists first discover in 1961?

C. The language of DNA. D. A message of DNA.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. |
| C．Make maps of human. |
| D．Make people less attractive. |
What do people think about this work?
| A．It can cause good or bad results. |

Cyril Dick’s house is neither a modern house nor a house of the future. It is 40 years old. There are more houses like that in the south of France. They are called “bubble houses”, and you can see why!
Cyril Dick is a designer and he loves round things. He collects old records and clocks. He also collects round furniture. And now he has a completely round house.
Everything in the “bubble house” is round. The centre of the house is one very big bubble. This is both the living room and dining room. There are round armchairs, a round table, and a big round rug(地毯) in front of a round fireplace. Around the living room are three small bubbles. One bubble is a kitchen with round shelves, another bubble is the garden room, and the third bubble is a music room. Upstairs there are two more bubbles—a bedroom and a bathroom.
The doors and windows are also round, of course. The windows are like eyes. There aren’t any curtains(窗帘) in the house, because Cyril likes to see the garden all the time.
Bubble houses are the idea of a Hungarian architect(建筑师), Antti Lovag. “A lot of modern houses are bad for us, especially tall buildings of flats,” says Lovag. “Because round homes are more natural（自然的）, people feel happy in them.” Cyril agrees with this. “Some people think my house is funny,” he says, “but for me, this is the perfect home.”

American people like to say “ Thank you” when others help them or say something kind to them. People of many countries do so, too. It is a very good habit(习惯).
You should say “Thank you” when someone passes you the salt on the table, when someone walking ahead of you keeps the door open for you, when someone says you have done your work well, or you have bought a nice thing, or your city is very beautiful. “Thank you” is used not only between friends, but also between parents and children, brothers and sisters.
