D）阅读下面的短文，根据短文内容回答问题。（10分）

New rules and behaviour standards(行为规范) for middle school students came out（颁布） in March. Middle schools are going to use a new way to decide who the top students are. The best students won’t only have high marks. The following are some of the new rules.

Tell the truth. Have you ever cheated(作弊) in an exam? Don’t do it again! That’s not something honest students should do.

Do more at school. Good students love animals and care for other people. April is Birdloving Month in China. Is your school doing anything to celebrate it? You should join! In that way， you can learn more about animals and how to protect（保护） them.

Be open to new ideas. Have you ever thought people could live on the moon? Maybe you’ll find another earth in space in the future. Everyone’s new ideas are important.

Protect yourself. Has a thief ever taken money from one of your classmates? Don’t let it happen to you. If you have to go back home late， you should let your parents know.

Use the Internet carefully. The Internet can be very useful for your study. But some things on the Internet aren’t for kids， so try to look at the good web pages（网页）. You can use the web pages for fun or homework.

36. What should the best students do in an exam? 

阅读下面的句子，根据文章内容进行判断，正确写“T”，错误写“F”。

Stop Yelling At Your Kids

Parenting is hard. If you’re a parent, I’m sure that I don’t need to tell you that our job is a tough one. When you're managing children, it can be difficult to remember that they are still learning. If you find yourself yelling at your kids more often than you want to, here are some ways that can help you reduce the yelling. I’ve been working on this for the past few months and I have to say,it’s been amazing for both the kids and me.

If you are having an argument with your child, you need to make sure you both take the time to really listen. It gives both of you time to think and really listen to each other, which is important. Kids are more likely to listen to you if you listen to them!

One of your biggest struggles is to remind yourself of appropriate expectations. You can’t expect that your youngest acts as responsibly as your oldest. You should lower what you expect -taking into consideration things like their age - it can make a big difference. You should do your best to take a moment before yelling and take in a deep breath. It makes a world of difference for you. Instead of yelling, you’d better whisper. It can also help diffuse any situation by making things quieter, not louder. Besides, the more time you spend with your kids, the better you’ll get at communicating with them. You’re both more likely to understand each other.

If your children aren’t listening or it seems they only don’t listen to you, you don’t take it personally. You should remind yourself that your kids are still learning and they’re not going to be perfect.

( )21. As a parent, you may know that parenting is an easy job.

( )22. Listening to each other is a good way to stop argument between parents and their kids.

( )23. Usually younger kids behave less responsibly than elder children.

( )24. Parents should lower their expectation for their kids.

( )25. Both yelling and whispering can help make things quieter.

参考答案：1. tips; 2.district; 3.date; 4.Unnecessary;5.data; 6.recheck;7.right

C

You speak, write a letter, make a telephone. Your words carry a message. People communicate with words. Do you think you can communicate without words? A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad.

When you put up your hands in class, the teacher knows you want to say something or ask questions. You shake your head, and people know you are saying "No". You nod and people know you are saying "Yes". Other things can also carry messages. For example, a sign at the bus helps you to know which bus to take. A sign on the door helps you where to go in or out. Have you ever thought that there are a lot of signs around you and that you receive messages from them all the time? People can communicate in many other ways. An artist can use his drawing to tell beautiful mountains, about the blue sea and many other things. Books are written to tell about all the wonderful things in the world and also about people and their ideas. Books, magazines, TV, radio and films all help us communicate with others. They can help us to know what is going on in the world and what other people are thinking about.

61. People communicate ________.

A.with words only B.in many different ways

C.in letters and drawings D.with smiles, tears and hands

考题 AYou may not realize it，but you are doing much more than just studying，when you are at school． School is also the place where you learn to get along well with people． But this is not al-ways easy． What can you do if you just don-t like one of your classmates? If you discover that you have problems getting along with your classmates or friends，the most important thing to learn is tolerance(宽容)． Tolerance is the ability(能/J ) to realize and respect(尊重) the differences in others． We can not change the way that other people do，so it is important to learn to live happily with them．Tolerance will make everyone get on better with each other． Getting to know someone may help you understand why they do things differently． Something different does not exactly mean that it is bad． Tolerance teaches us to keep an even temper and open mind ．You need to remember an old saying，"Treat others how you want to be treated"． You would like to be treated kindly by your classmates，so it is important to treat them kindly too．If you tolerate(宽容) something，it does not mean that you have to like it． No one is asking you to change who you are or what you believe in． Tolerance just means that you should respect the differences in others and not try to make them change．It is important to practice tolerance，because it will make everyone's lives easier． Learn to accept(接受) people for their different abilities and interests． The world is very different，and practicing tolerance in your own school and city can help you make a difference．21． What does the writer think of school?At school，students can not only study but also_________________________正确答案：21． learn how to get on well with people 【解析】由第一段的第二句可知。

考题 共用题干 Looking to help the environment?Consider the following simple ideas.Turn off electrical devices when they're not being used.Turning off,rather than leaving on stand-by,things like your TV and computer will save huge amounts of energy. With this,we can all help reduce the amount of carbon dioxide emitted into the earth's atmosphere,thereby reducing pollution and global warming.Share your car.Rather than traveling to work alone,why not arrange car-sharing with one or more of your friends or colleagues?To give you an example,if you drive a fashionable car,you will use more energy in a year than you would leaving your fridge open for seven years,or your TV on for thirty-two years!Imagine the savings if you shared your car with 2,3 or even 4 other people!Refuse junk mail.While we all complain about how much junk mail we get,we very rarely do anything about it. The mail continues to go straight from our letter-boxes into the garbage bin-with 99% of it not even opened.What can you do about this?There are various websites where you can register to receive no junk mail.As well as saving time,you'll also be doing a lot for the environment. Each year,100 million trees are used to produce junk mail. 250,000 homes could be heated with one day's supply of junk mail.There are many other everyday changes you can make to help the environment. They will cost you nothing,and many will actually save you money!Why not give it a try?We can all help, if we really want to. The only drawback of junk mail is that it wastes out time.A: RightB: WrongC: Not mentioned答案：B解析：关闭不用的电视和电脑可以节约大量的能源。本句话和文章第一个小标题下的内容相一致：切断你家中类似电视和电脑等电器的电源，不要让它们时刻处于待用状态，这样会节省大量能源。和冰箱、电视相比，开车浪费很多能源。根据Share your car那一段中：当你驾驶着你的时髦小桥车时，你消耗的能源比打开冰箱门7年，或让电视一直开犯年所耗的能源还要多。可以推断出作者是在暗示和冰箱、电视相比，开车浪费很多能源。因为汽车非常浪费能源，所以我们不应该买车。该文章中并未涉及这一内容。99%的垃圾信件没有被打开就被扔进了垃圾箱。根据Refuse junk mail那一段的第二句话：垃圾信件还是被我们从信箱中取出然后直接扔到垃圾箱，其中99%的信件甚至从未打开过。可以推断出本句话是正确的。垃圾邮件的唯一缺陷就是它浪费了我们的时间。根据文章中第四段的最后两句话：这样在节省时间的同时，我们也为环保做出巨大贡献。每年都会有一亿裸树被砍伐来制造垃圾信件。可以得出本句话是错误的。要保护环境，我们必须要花好多的钱。本句话和文章最后一段第二句话相矛盾：这些改变其实不花费我们任何精力，其中许多还可以为我们省钱。因此是错误的。即使我们想做些改变去帮助改善环境，我们也无能为力。根据文章最后一句话可以得知只要我们愿意去做，我们都可以做到，本句话和文中内容矛盾，因此本句话是错误的。

考题 We all know that humans are damaging the environment，but what can we do about it?Some people are trying to do their bit to be more environmentally friendly.Local councils in Britain encourage certain aspects of green living，such as recycling paper，tin，plastic and glass. They want to reduce the amount of rubbish going into landfill sites(填埋场)，because they are running out of places to dump(倾倒)rubbish. In some areas rubbish for recycling is collected from your doorstep，but in other areas，you have to take it to a special recycling place，such as a bottle bank.Another way of reducing the amount of rubbish you create is to use reusable products instead of disposable ones. For example，some people use strong shopping bags or boxes for their groceries instead of plastic carrier bags，or use washable nappies instead of disposables.More people are becoming interested in reducing their carbon footprint-the amount of carbon they use up. They try to reduce their carbon emissions(释放)by cycling，using public transport or an electric car，rather than driving gas-consuming vehicles. Some people choose not to fly for holiday trips because planes are the biggest producers of carbon emissions.You can make“green”choices when buying food too. It's best to buy food which was locally grown or produced so that it hasn't been imported by air，or shipped by road from far away.Houses can be environmentally friendly too. It takes less energy to heat a house if it has good insulation(绝缘，隔热)and double glazing(双层玻璃). You can also create your own energy if you have solar panels or a wind turbine fitted though these can be expensive. You can also save water by using a rain water container for washing the car or watering the garden. It's even possible to use a system where“grey water”-water which has been through a tap(水龙头)once already，is used to flush(冲洗)toilets. Some new housing projects are being built specifically to be as environmentally friendly as possible.The purpose of collecting reusable wastes is to______.A．save energy consumed in daily lifeB．reduce the amount of rubbish dumpedC．create a new way of green livingD．decrease the amount of carbon produced正确答案：B解析：见第二段，他们想减少运往填埋场的垃圾，因为已经没有地方可以倾倒垃圾了。所以收集可再用垃圾的主要目的是为了减少垃圾倾倒。

考题 共用题干 Motion SicknessLiving in space looks like lots of fun.You can do certain things in space(like floating around,or pushing huge objects)that you cannot do on earth.But being in space can do things to you,too.If you stay too long in a gravity-free environment,your bones could become weak,and a small spaceship just might annoy you after a while,because space travel could make you seasick!On July 4, 1982,after seven days orbiting the earth,astronauts Thomas K. Mattingly and Henry W. Hartsfield returned home.Although not all of the experiments on board worked properly,the flight basically seemed to be a success except for one"little"thing: early in the flight,astronaut Hartsfield became"seasick".Thomas Mattingly,who is also a jet pilot and is highly resistant to motion sickness on earth,did much better.Mattingly sailed through space with a steady stomach.But no one knows why Hartsfield felt uneasy and Mattingly did not.So far it seems there is no reliable way to predict who will become motion sick in outer space and who will not.In all,at least four astronauts have suffered from space motion sickness. Russian and American scientists are working together to try to understand and solve the motion sickness.Space program officials worry that if so many highly-trained pilots get sick in space,what will happen when civilians start flying in the shuttle?Motion sickness is a disagreeable feeling that comes from the pitching,rolling, swaying,or just the moving of the object you are riding in or on.Symptoms of motion sickness include:dizziness,headache,a sinking feeling in the stomach,and vomiting （呕吐）.Why does motion make some people ill?Doctors believe that motion sickness is caused by a disturbance in the inner ear.Our ears do more than give us hearing.A part of the ears gives us a sense of balance and helps make us aware of whether we are right side up or upside down.If you know that you get carsick or seasick,what can you do?Speak to your doctor. There are certain medicines available that can help stop that uneasy feeling.But many of them can also make you sleepy.Usually they work best takenbefore you begin feeling ill.Some people also recommend water,ice cubes,mints,or plain toast.But these remedies do not always work for everyone.Perhaps,since motion sickness is such a big problem in outer space,researchers may soon find a way to cure the astronauts一and those of us who stay on earth.Floating in space for too long a time may also do harm to one's lungs and heart.A:Right B:Wrong C:Not mentioned答案：C解析：

考题 共用题干 第一篇Carbon FootprintHow often do you travel by plane?How much electricity do you use?These days everyone is worried about the size of their carbon footprint.In order to reduce global warming we need to make our carbon footprints smaller. But how much CO2 are we responsible for?A new book might be able to help.The Carbon Footprint of Everything looks at the different things we do and buy,and calculates the amount of CO2 all of the following created:the ingredients, the electricity used in the brewery，the equipment,the travel and commuting of the beer,and the packaging. It's amazing how many different things need to be included in each calculation.And it's frightening how much carbon dioxide everything produces.But all of this can help us decide which beer to drink.From Berners-Lee's calculations,it's clear that a pint(568ml)of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer. This is because the imported beer has been transported from far away,and it uses more packaging. The local beer only produces 300g of CO2,but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket.Berners-Lee has even calculated the carbon footprint of cycling to work.Nothing is more environmentally-friendly than riding a bike,surely?Well,it depends on what you've had to eat before. To ride a bike we need energy and for energy we need food.So if we eat a banana and then ride a kilometer and a half,our footprint is 65g of CO2.However,if we eat bacon before the bike ride,it's 200g. In fact,bananas are good in general because they don't need packaging,they can be transported by boat and they grow in natural sunlight.So,does this mean that cycling is bad for the environment?Absolutely not,for a start,if you cycle,you don't use your car,and the fewer cars on the road,the fewer traffic jams.And cars in traffic jams produce three times more CO2 than cars traveling at speed.Cycling also makes you healthy and less likely to go to a hospital. And hospitals have very big carbon footprints!So maybe it's time for us all to start making some changes.Pass me a banana and a pint of local beer,please.To make our carbon footprints smaller,we should often________.A:cycle to workB:drink more local beerC:calculate the amount of CO2D:buy cheap things from the supermarkets答案：A解析：细节题。根据原文可知以下产生的二氧化碳量分别是：A选项，一品脱当地酿造的啤酒为300克，B选项，一品脱进口啤酒为900克，C选项，骑车前吃的香蕉为65克， D选项，骑车前吃的培根肉是200克。词义推断题。第三段第二句：原料、xxx所用的电量、设备、啤酒的运输和包装。由此可知A最合理，B’选项与原文的“设备”重复了，D选项同理，C选项与包装重复了。推断题。从第六段可以看出骑车是环保的，产生的碳足迹是少的，其他选项都没有在原文中体现这个意思。推断题。第五段最后一句：香蕉总体来说是很好的，因为它们无需包装，可以使用船只运输，并且在自然光照下生长。这些都是说香蕉产生的碳足迹少，并没有提到它是健康食品。A、B、D原文均有体现。主旨题。本文大意是阐述了我们的碳足迹量有多少。A、B和C均只是原文中的一点。

The mail continues to go straight from our letter-boxes into the garbage bin-with 99% of it not even opened.What can you do about this?There are various websites where you can register to receive no junk mail.As well as saving time,you'll also be doing a lot for the environment. Each year,100 million trees are used to produce junk mail. 250,000 homes could be heated with one day's supply of junk mail.There are many other everyday changes you can make to help the environment. They will cost you nothing,and many will actually save you money!Why not give it a try?We can all help, if we really want to. By turning off a TV or computer that's not being used,you will save a lot of energy.A: RightB:WrongC: Not mentioned答案：A解析：关闭不用的电视和电脑可以节约大量的能源。本句话和文章第一个小标题下的内容相一致：切断你家中类似电视和电脑等电器的电源，不要让它们时刻处于待用状态，这样会节省大量能源。和冰箱、电视相比，开车浪费很多能源。根据Share your car那一段中：当你驾驶着你的时髦小桥车时，你消耗的能源比打开冰箱门7年，或让电视一直开犯年所耗的能源还要多。可以推断出作者是在暗示和冰箱、电视相比，开车浪费很多能源。因为汽车非常浪费能源，所以我们不应该买车。该文章中并未涉及这一内容。99%的垃圾信件没有被打开就被扔进了垃圾箱。根据Refuse junk mail那一段的第二句话：垃圾信件还是被我们从信箱中取出然后直接扔到垃圾箱，其中99%的信件甚至从未打开过。可以推断出本句话是正确的。垃圾邮件的唯一缺陷就是它浪费了我们的时间。根据文章中第四段的最后两句话：这样在节省时间的同时，我们也为环保做出巨大贡献。每年都会有一亿裸树被砍伐来制造垃圾信件。可以得出本句话是错误的。要保护环境，我们必须要花好多的钱。本句话和文章最后一段第二句话相矛盾：这些改变其实不花费我们任何精力，其中许多还可以为我们省钱。因此是错误的。即使我们想做些改变去帮助改善环境，我们也无能为力。根据文章最后一句话可以得知只要我们愿意去做，我们都可以做到，本句话和文中内容矛盾，因此本句话是错误的。
