题目内容

【题目】The weather is getting hotter and you’ll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.

There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition list also contains various things from vitamins to ginseng. Sounds great!

But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.

Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.

Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 percent of boys aged 8-12 take in more caffeine than their parents.

There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.

Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。
One day, my brother and I were alone in our apartment. The reason was that my parents had both gone for a ball party and had left me in charge of everything. I was doing my homework while my younger brother was watching television. Suddenly, the doorbell rang. Ding-Dong! Ding-Dong! My younger brother had rushed to the door before I decided to answer the door. We both thought that our parents had come home. As a result, he unlocked the door and opened it.
Outside of the house stood a man who wore a black raincoat and black rubber boots. He looked no different from other people and he said that he was a salesman and asked politely if our mother or father was at home so he could talk with them.
Without any thinking, my brother said, “No.” He asked if we would like to buy some comic books, which he was selling. I quickly explained to him that we were not supposed to buy anything without our parents' permission. However, it seemed that he was not willing to follow my advice and he had an intention to enter our house.
Then I realized something terrible would happen. As I was about to close the door, he forced his way into our house. He took out a knife and forced me to tie up my brother's hands with some rope which he took out from his pocket. I tied up his hands but I tied in a special way so my brother could untie himself as we often did. The man then tied my hands up and locked both of us in the kitchen.
Soon he went upstairs to search the bedroom for something valuable. I managed to teach my brother to untie the rope on his hands. He then untied me. I rushed to the telephone to call the police, but the line was dead.

【题目】It goes without saying that English plays an important role in our modern society.English is an international language.Wherever you go,you can hear English spoken by many people.From this point of view,it is true that English is important to our daily life.

Learning English is like learning to swim or learning to play ball.We are like the man who thinks he can learn to swim only by reading books about swimming.In fact,we learn by doing.The grammatical rules are valuable as we need some assistance.In the same way,advanced instructions about swimming are helpful as we learn something from actual experience in the water.But reading books never makes a swimmer and learning rules never makes a practical linguist.The regular procedure in learning English involves listening first,to be followed by speaking.Then comes reading,and finally the writing of the language.The way you learn English is much the same as the way you learned your own language.First of all you must listen and then repeat and repeat until you can use the language easily.In other words,you have to build up language habits in English just as you build up English habits in your own language.

To sum up,we must bear in mind that nobody can learn to swim for you.Nobody can learn to play ball for you.Nobody can learn English for you.It’s up to you.You must learn for yourself and you will learn if you really want to and are willing to practice.
