It's important to learn about protecting our environment. Here is a 5R rule for us:
Reduce
If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste
Reuse
You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.
Recycle
Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat(压平) and melted (融化) and the melted things are made for new coke cans. Recover
When you buy a box of apples, there may be a few rotten(腐烂的) apples. You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.
Repair
If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repairs. It is true that North America is a "throw-away" society(社会). But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
A. Only hard things C. Few soft things
A. to throw waste things away B. to cover waste things with earth
B. Many things D. All things
C. to get back the useful parts D. to throw the whole things away A. China B. Japan C. Australia D. America 63. We can infer(推断B
There is little doubt that house cat first developed naturally from ancient wild cats. The cleverest relative is the America wild cat which still lives in Africa today. This is understandable because the first house cats came from Africa.
Cats first started to live around people in Egypt about 6,000-7,000 years ago. From Egypt, cats started to move around the world. This is about the same time that Egyptians began storing grain(谷物) in cats don't like to be told what to do! Now, scientists believed that cats followed the mice and learned to accept people. Finally, some of the cats began to grow comfortable around people, these were smaller cats that needed protection. As these cats and people got used to each other, then they moved in together. Around 5,000 years ago, cats started to live with people.
Soon cats were in Greece, then the Middle East and China. They moved along Egyptian business roads keeping away mice and keeping people around them. After the Romans came to Egypt, they also accepted the cats and brought them to Europe. These cat likely bred(繁殖) with other cats to form the many kinds of house cats we have today.
Cats are relatively recent house animals. House cats still have a lot in common with their wild relatives. Cats sleep a lot to save energy just like wild cats. They will often get food at night as well. House cats are generally peaceful and friendly, but be careful! If a cat feels it is in danger, it will fight back—just like a wild cat.
64. Where did the first house cats come from?
A. Asia. B. Africa. C. Europe. D. America. 65. When did cats start to live with people? A. About 4,000 years ago. C. About 6,000 years ago. B. About 5,000 years ago. D. About 7,000 years ago. 66.

Cats have a little in common with their wild cats. D. Cats were accepted and brought to Europe by Romans. A. 驱散 B. 捕捉 C. 驯化 D. 引进 67. What does the underlined word "tamed" mean in Chinese? 68.

You're buying a used car, moving into a new house, or deciding which doctor should treat your illness. These are times when you need to get directly to the core(核心) of an important matter.
Asking general questions gets little valuable information and may even result in unreal answers, says Julia Minson, a visiting scholar in decision sciences at the University of Pennsylvania in the US. The best way, says Minson, is to ask a lot of questions that discover there are problems.
Let's say someone is selling a used iPod. An example of a general question is "What can you tell me about it?" A positive-assumption(正面推测) question is "There aren't any problems with it, right?" But a negative-assumption question, such as "What problems have you had with it?" will get the most honest answer, found Minson and her team.
In a study, 87% of the sellers warned the buyers to problems when asked a negative-assumption question, while 59% of those did the same thing to a positive-assumption one.
When you want the truth, you have to ask for it. What problems does this car have? What are the worst parts of this job? How many people with my kind of illness have been successfully treated? Your questions should communicate that you are sure there will be difficulties and that you want to know about them.
69. What can we do if we want the truth, according to the passage?
A. Ask for it ourselves. C. Study it ourselves. A. General questions. B. Positive-assumption questions. C. Careful questions. D. Negative-assumption questions. A. How to Find Honest People C. How to Get an Honest Answer B. Talk with honest people. D. Do some experiments. 70. What kind of questions has the best result? 71. Which of the following can be the best title for the passage? B. How to Talk with Others D. How to Avoid Being Cheated

Sometimes you think your teacher hates you? You're not the only one. Teachers and students sometimes have personality clashes(冲突), just like any two people who don't get along. After all, teachers aren't perfect.
However, most of the time, there are a lot of reasons why you complain about your teacher's bad attitude(态度) to you. So try to find out if your teacher really does dislike you. Or something else is going on. Here are some questions to ask yourself:
* Is your teacher angry at you personally, or at something you've been doing?
All teachers have something that they strongly dislike. Maybe your teacher hates it when people whisper(低声说话) in class. If you try hard not to do these things, the situation might get better.
* Are you the only person being treated badly, or is your teacher shouting at the whole class?
Ask your classmates if they've been having trouble with the teacher too. If they say yes, perhaps your teacher is having problems outside of school, or is new and feels something badly.
*Are you working up to your ability?
You and the kid sitting beside you both got a C on the last test, and your teacher told you that you could do better, but didn't say anything to her! Isn't this unfair? Well, teachers often treat different students in different levels in different ways. They will be angry if they feel someone does not do the work he is able to. It's their way to encourage a student to try a little harder.
* Are you more sensitive(敏感) than most students?
Try to find out if you are very sensitive to be criticized(批评). If the other students aren't as sensitive, they will not be in such trouble even though the teacher treated them the same way. There's nothing wrong with being sensitive, but if you act to criticism differently than most kids, this would be the reason why you think your teacher doesn't like you.
A. not a matter at all C. something normal A. ask his classmates for help B. think more about himself C. talk with the teacher at once D. treat the teacher the same way A. get along with their teachers B. do during a class as a student C. understand the teachers' feeling D. act when they are criticized B. a serious problem D. no good for students 七、短文7选5(5选5等)（共5小题；共10分）

Everyone Can Change the World
What can we do to help protect the environment? It seems useless to just pick up a piece
of trash(垃圾), but what will happen if you keep doing it every day? Tommy Kleyn, an ordinary man from the Netherlands, may give you the answer.
Tommy Kleyn walked past a polluted river on his way to work every day. It used to be a beautiful view, but the trash on the bank made it dirty and smelly. So Tommy decided to pick up the trash along the river a little bit at a time after work. "It took me about 30 minutes to fill one garbage(垃圾) bag with trash, but one garbage bag didn't seem helpful in a place as polluted as this. I decided to fill one bag of trash each day as I passed by," Tommy said. Every day, Tommy took pictures of the river and shared them on his Facebook page. To his surprise, in just six days, he had made great progress with his cleanup effort(努力). He felt happy and kept doing it. Gradually, more and more people knew about Tommy's story. Other people in the community began following in his footsteps and cleaning up trash on their way home, too. "The idea is to encourage people to fill one garbage bag with litter each day. It only takes 30 minutes, but it really makes a difference and you will be amazed at how good you feel afterwards," he said.
People from all over the world have been moved and inspired(激发) by Tommy's story. No effort is useless if we keep doing it every day. Ordinary people like you and me can also make a difference to the world we live in if we take actions right now.
