举一反三
Every living thing on the earth is made up of cells(细胞). Cells grow and make new cells. Most cells are very small and we can"t see them with our eyes. Different cells have different uses. Our skin cells are special ones. The cells on the outside of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells. They work for our bodies. They help protect our bodies and heal cuts.
Our bodies make skin cells all the time. As the old cells fall off, new cells grow in the same place. Each person makes about 18 kg of skin cells during his or her life. Outside skin cells fit together closely with no gaps between them. When you cut yourself, you can harm your skin cells. A small cut will not be harmful. Your skin will quickly heal itself by making new skin cells. How do skin cells work? First, the cells near the cut get bigger and move into the gap. Next, these bigger cells meet in the middle. They form a new layer(层) of skin cells. Finally, new cells will grow until the gap disappears. In this way, your skin can grow and get well itself. How amazing the small cells are! Next time you have a cut, don"t worry about it. Maybe in a few days, you will be surprised to find it healed.
小题1:The underlined word “gaps” in the passage means “______” in Chinese.
A.突起 | B.条纹 | C.缝隙 | D.代沟 |
A.are large and we can see them with our eyes |
B.can heal few cuts themselves |
C.are in everything on the earth |
D.can grow and make new cells |

A.Each person can make 18 kg of skin cells every day. |
B.Different cells have different uses in our bodies. |
C.The skin cells have little work to do in the body. |
D.Every living thing on the earth is made up of skin cells |

C.How to Protect Our Fingers |
D.The Importance of Cells |
Whether it is caused by cold or flu(流行性感冒), a runny nose and sore throat are signs of catching a cold. Many people overestimate(高估) the advantages of vitamin C and other pills. For years it was believed that taking vitamin C pills not only provided protection against colds but also against cancers, helping people to live longer. But the result of the research showed disagreement on these beliefs(看法). The result has now come out on the website wwww.informedhealthonline.org. “Some pills may not help people live longer. Some pills may even lead to earlier death,” says Professor Peter Sawicki. Scientists also say that the best way to get vitamins is through food instead of having vitamin pills. That is to say, we disagree with the way of taking vitamin C pills.
There are many simple but useful ways to lower the risk of catching a cold. These include often washing your hands with normal soap(肥皂) and water and not touching your face with your hands. People who have already had a cold can stop it from spreading by throwing away tissues(纸巾) at once after using them and not shaking hands with other people.

Maybe that doesn’t sound interesting. But when we’ve joined the internet, there are lots and lots of things wecan do. We can have a lot of interest on the World Wide Web (WWW). We can use the Internet instead of a libraryto find all kinds of information for our homework. We can find information about our favorite sports or film starsand do shopping on the Internet.

English schools begin in September after a long summer holiday. There are two terms in a school year. The first term is from September to January, and the second term is from February to June. Most English children begin to go to school when they are five years old. When they finish high school, they are seventeen or eighteen years old.
High school students take only five or six subjects each term. They usually go the the same class every day, and they have homework for every class. After class, they do a lot of interesting things. After high school, many students go to college①. They usually have to pay a lot of money. So they have to work after class to get money for their studies.
