In most parts of the world, many students help their school make less pollution. They join “environment clubs”. In an environment club, people work together to make our environment clean. Here are some things students often do.
●No rubbish lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least rubbish and report them to the whole school.
●No car day. On a no car day, nobody comes to school in a car---not the students and not the teachers! Cars give out harmful gases to pollute out air, so remember:
Walk, jump, bike or run.
Use your legs. It’s lots of fun.
●Turn off the water! Do you know that some toilets can waste 20-40 m3 of water an hour? In a year, that would fill a small river! In environment clubs, students mend their broken toilets.
We love our home---the Earth. Let’s work together to make it cleaner and more beautiful.
（ ）1. Environment clubs ask students ____________.
A. to run to school every day B. to take exercises every day
C. not to forget to take cars D. not to throw away lunch bogs
（ ）2. From the passage we know the students usually have lunch_________.
A. at school B. in shops C. in clubs D. at home
（ ）3. On a no-car day, _______will take a car to school.

综合练习：
一、完型填空：
11. B chance“机会”，advice“建议”，excuse“借口”，business“商业”。根据文章最后一段的“So my advice is this: If a snake bites you, pick up your phone.”可知选B。
12. A suddenly“突然”，nearly“几乎”，especially“尤其”，fortunately“幸运地”。根据文章叙述，应该是“突然”一条蛇出现了，咬到了杰克逊先生的手。
13. C 通过前文“...Henry Jackson was working in a restaurant kitchen.”可知故事应该是发生在一家饭馆里，所以本题选择restaurant。
14. B 根据文章含义可知应该是这条蛇爬出了箱子然后“藏”在盘子底下，故选择hid（原形hide“隐藏”）。hung（原形hang“悬挂”），jumped（原形jump“跳”），ran（原形run“跑”）均与文意不符。
15. D under“在……下面”，into“进入”，towards“朝”。不能将蛇扔到厨房下面，故排除under；根据前文我们知道这条蛇本来就在厨房内，所以throw...into“扔进（厨房）”和throw...towards“扔向（厨房）”均不符合逻辑。故只有D符合题意，throw it across the kitchen意为“把它从厨房的这一边扔向那一边”。
16. A stay cool意为“保持冷静”，说的是杰克逊先生保持镇静，用手机给蛇拍了一张照片。其他形容词noisy（吵闹的），pleased（满意的），afraid（害怕的）都与文意不符。
17. C 从前文“bit him on the hand”可知“Soon his hand began to ache...（很快他的手开始疼……）”，所以选hand。
18. D 通过“Doctors couldn’t say what was wrong”和“they didn’t know what kind of snake it was”可知“医生说不清楚状况”的原因是“他们不知道这条蛇的种类”，所以选because。
19. B send sth. to...意为“把某物送/寄到……”，根据文章含义，医生把杰克逊先生拍摄的照片发送到伦敦动物园。
20. C 从全文可知杰克逊先生给大家的建议是如果蛇咬了你，给它拍照。所以本题应用it（蛇）的形容词性物主代词its。
三、语法填空 1—5 DACCA 6—10 BCACD
阅读理解
26. C 由第一段信息中“About 60 people were hurt...”可知，大约有60人在火车相撞事故中受伤。
27. C 由第二段信息中“Over 180,000 tourists visited the place of great interest from April 29 to May 1, during the three day holiday.”可知，在“五一”假期中许多人参观泰山。
28. B 由第三段信息可知，汶川地震中失去女儿和腿的成都舞蹈教师廖智，在震后到雅安当起了志愿者。
29. D 由第四段信息中的最后一句“The competition hoped to encourage the farmers to grow better tomatoes.”可知，比赛的目的是鼓励农民种出更好的西红柿。

The Earth is a beautiful place. There are forests and rivers, mountains and fields. Some places are hot, and some are very cold.
There are many different plants. Some are large. Some are small. All plants need light and water. There are different animals on Earth too. Some live on the land. Some fly in the sky. Some live under the water.
There are also many people like you and me on Earth. The Earth provides us with air, water and food. It is our home.
Today, there is a lot of pollution. We burn things to make energy. This pollutes the air. We put our rubbish into the sea and under the ground. This pollutes the Earth and kills animals and plants.
We must stop doing these things. It is important for us to protect the Earth for our future.
