Some people even have no clean water to drink.Recently, a new life style called low carbon（低碳）life is spreading every corner of our country. The meanings of low carbon are 2 energy and no waste. It is such an important project that I cant wait to express my ideas on how to promote it.First, we should 3 a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy. 4 the no-car day, neither students 5 teachers are allowed to drive to school. At the same time, just walk or run. Use our legs and enjoy the fun.Second, we had better not use plastic bags 6 . No one can stand the“white pollution”, 7 it is wise to use cloth bags which can be used again and again. 8 , one thing that we should keep in mind is that every big thing comes from the small details. So, as students, we ought to turn 9 the lights the moment we leave, use 10 sides of the paper, and reuse our textbooks and so on. All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these：no-car days, no plastic bags, and no waste. Lets do it now. 1.

Then whats the worlds largest fish? Its the whale shark (鲸鲨).Although the whale shark is our biggest fish and lives in many oceans (海洋) around the world, few people have ever heard of it. Scientists have not been studying whale sharks for very long. Much more needs to be learned about them.A whale shark is sometimes called a “gentle giant (温柔的巨人)”. It likes to be alone and doesnt care a bit about divers or humans. The biggest whale shark weighed 24,250 pounds and was nearly 40 feet long. This makes it heavier and longer than a school bus. Inside its huge mouth are great numbers of very small teeth. To count all of them, youll need to do some math. The whale sharks teeth are arranged in rows. There are between eleven and thirteen rows on each jaw (颚) and around three hundred teeth in each row. However, the whale shark rarely uses its teeth. It does not chew or bite its food. Large amounts of water are pulled into its mouth and then pushed out through its gills (鳃). For a few months every year, a group of whale sharks comes to Ningaloo Reef, off Western Australia. This gives scientists a wonderful chance to study the large fish. Whale sharks do live in other oceans of the world, but no one knows their population. It is possible that our biggest fish may need protecting. It is one of the reasons why scientists continue to learn all they can about these gentle giants.1. Little is known about whale sharks because scientists _.A. are not interested in learning about themB. find them too difficult to catchC. do not know the best places to find themD. have studied them for a short time2. Which sentence can tell us that whale sharks are gentle?A. They have large mouths.B. They leave divers alone.C. They have small eyes. D. They live in many oceans.3. How does the writer help us know what the whale sharks mouth looks like?A. By giving reasons.B. By describing colors.C. By comparing sizes. D. By using numbers.4. The fifth paragraph is mainly about _.A. how a whale shark eatsB. what a whale shark eatsC. how different fish use their gillsD. whats inside a whale sharks mouth5. Which of the following is the best title for the article?A. Gentle Giants B. The Diary of a SailorC. The Largest AnimalD. My Life on the Sea. 书面表达目前，全国许多市持续出现雾霾天气，陷入大范围的重度和严重空气污染。请您根据要点提示，联系实际，适当发挥，以Lets do something to keep hazy weather away为题写一篇报告。内容要点：1. 雾霾原因：工厂废气和汽车尾气的排放；2. 导致问题：（1）空气污染，不敢开窗，外出需戴口罩，学生停止户外活动； （2）因能见度低导致交通事故，飞机延误； （3）3. 采取措施：（1）作为学生（至少1条）； （2）号召人们（至少l条）。写作要求：90词左右。文章开头已给出，不计入总词数；注意书写工整和标点符号的规范使用。参考词汇：雾霾 hazy；废气waste gas; 口罩mask; 延误 delay重点句型（Unit 2 Saving the Earth - Topic 1 Pollution has caused too many problems.）同步练习参考答案. 1.
