They must not be crowded（拥挤）. Fish need oxygen(氧气). Fish get it from water in the tank. There must be enough water for all fish in the tank. So the size of the tank（箱子）is important.In the tank many people put small plants(植物). They give oxygen to the water. Plants help in other ways, too. Fish can nibble(轻咬)on the plants. They hide in the plants and sleep, lay eggs there.Both the plants and fish need light. You can put near a window. It will get light there. But remember: a window may let cold air in. The cold can kill(杀死) your fish. Too hot water can kill your fish, too.The fish need food and you should feed them every day. Giving them too much food is bad. It will make the water dirty. However, the fish should get just enough food. They should finish the food in 10 minutes. No extra(多余) is left. When this happens, the amount(数量)of food is right.( )1.

He doesn't have anyone to play with. "Don't worry!" says his mother. "You will soon make friends here."One morning, there is a knock at the door. Bob's mother, Mrs White, opens it. There stands a woman with brown hair. It is Mrs Miller. She comes to borrow two eggs. She wants to make cakes. Mrs White gives her two. In the afternoon there is another knock at the door. Mrs White opens it and she sees a boy standing there. "My name is Jack Miller," he says. "My mother sends you this cake and the two eggs."Well, thank you , Jack," says Mrs White. "Come in and meet my son Bob.Look! Bob and Jack are having cake and milk. They are playing football. Now they are friends! Jack says, "I'm glad you live next door." Bob says, "I must thank your mother for coming to borrow eggs." Jack laughs and tells Bob, "My mother doesn't want the two eggs, but she wants to make friends with your mother.

The best title of this passage is _____.A. Way to Borrow EggsB. Way to Make CakesC. Way to Make FriendsD. How to Make Cakes（C）Students work very hard but many are unhappy. They feel heavy pressure(压力)from their parents. Most parents always tell their children to study harder so that they can have a wonderful life. Though this may be a good idea for those very clever students, it can have terrible（严重的）results（结果）for many students because they have difficulties in their studies.As it is reported (据报道), some students killed themselves. Some join the groups of trouble makers（制造者）. Many of them have tried very hard at school，but they have failed（失败）in the exams and it makes their parents lose hope. Such students feel that they are hated by everyone else they meet and they don’t want to go to school an y longer, so they become dropouts.It is surprising that though most parents are worried about their children, they do not help them in any way. Many parents feel that they are not able to help their children and that it is the teachers’ work to help t heir children. To make matters（情况）worse, a lot of parents send their children to those schools opening in the evening sand（晚自修）on weekends. Those schools only help students to pass exams. It is a great surprise that almost three quarters（四分之一））of middle school students have been to such kind of schools. Many schools usually have rules（规定）about everything, from the students’ hair to their clothes and the things in their school bags. In fact, such strict（严格的）rules may hurt the feelings of the students. Almost 40% of the students said that no one had taught them how to get on with others, how to tell（分辨）right form wrong and how to show love to others, even to their parents.( )11.

Are you _____________(will) to help us with our English?14. Please tell her_____________ (not wake) me u p this evening.15. Our teacher made us _____________ (stand) in a line.五、任务型阅读（10）Have you heard about “Survival (生存) Holidays”? “Survival Holidays” is for children to go into the lonely place for exciting activities. Now about 1,100 companies(公司) are asked (被邀请) to take children into the great outdoors without their parents.The reason why people like “Survival Holidays” is that they think being close to nature (大自然) is good for children. Many children in big cities spend all time watching TV and playing computer games. “Survival Holidays” gives them an important change.Is “Survival Holidays” a wonderful idea? Maybe it is. Children need more free time to play. They need to be left(被留下) on their own, without adults disturbing (打扰) them. Parents care too much about their children. They like to see the children being busy with activities that are controlled (支配) by adults, but children don’t know what to do when they are in danger. Even something like crossing a small river seems to be a hard challenge (挑战). Children are not comfortable with danger. Even small danger like getting their feet wet or falling down seems very terrible (可怕的) to them. Many people think the survival activities are good for children. Even years later, they will still remember what they have learned. Some have learned to stay calm in different times. Some have learned how to keep safe. Others have learned how to work in a team.

If so, you will find Being a Happy Teenager written by an Australian writer Andrew Matthews.In his book, Matthews tells us how to have a happy life and answers the questions of teenagers.There are many subjects, such as parents and friends, and the book says we should stop being angryand should forgive(宽恕). The book tells us some useful skills, such as how to put what you have learnedinto pictures of your mind to, make your memory better. Many teenagers think that happiness comes from a good exam result or 'praise(费扬) from other people. But you can still be happy when there are no such "good" things.Success comes from a good attitude(态度). If you learn from problems, you will have success in thefuture. Some school students have problems, such as being too tall or too short. But Matthews tells us that happiness comes from thinking in a positive(积极的) way. If you are tall, people notice you and you canget a better view(视线) at the movie; if. you are short, your clothes and shoes take less room in yourbedroom! This is Matthews' most important lesson: 6*You choose to be happy! "根据短文内容，回答下列问题。
