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 life
B．reduce the amount of rubbish dumped
C．create a new way of green living
D．decrease the amount of carbon produced

The process of perceiving others is rarely translated(to ourselves or others) into cold,objective terms．"She was 5 feet 8 inches tall, had fair hair, and wore a colored skirt．" More often, we try to get inside the other person to pinpoint his or her attitudes, emotions, motivations,abilities, ideas, and characters． Furthermore, we sometimes behave as if we can accomplish this difficult job very quickly--perhaps with a two-second glance．
We try to obtain information about others in many ways． Berger suggests several methods for reducing uncertainties about others; who are known to you so you can compare the observed person's behavior with the known others' behavior, observing a person in a situation where social behavior is relatively unrestrained or where a wide variety of behavioral responses are called for,deliberately structuring the physical or social environment so as to observe the person's responses to specific stimuli, asking people who have had or have frequent contact with the person about himor her, and using various strategies in face-to-face interaction to uncover information about another person--question, self-disclosures, and so on．
Getting to know someone is a never-ending task, largely because people are constantly
changing and the methods we use to obtain information are often imprecise． You may have known someone for ten years and still know very little about him． If we accept the idea that we won't ever fully know another person, it enables us to deal more easily with those things that get in the way of accurate knowledge such as secrets and deceptions． It will also keep us from being too surprised or shocked by seemingly inconsistent behavior． Ironically, those things that keep us from knowing another person too well (e． g． secrets and deceptions) may be just as important to the development of a satisfying relationship as those things that enable us to obtain accurate knowledge about a person (e． g． disclosures and truthful statement)．
Some people are often surprised by what other people do． According to Berger, that is mainly because__________．A.some people are more emotional than others
B.some people are not aware of the fact that we will never completely know another person
C.some people are sensitive enough to sense the change of other people's attitudes
D.some people choose to keep to themselves

Ecosystem1. The word “ecosystem” is short for ecological（生态的）system. An ecosystem is where living creatures expand within a given area. You can say that an ecosystem is the natural environment where biological organisms（生物）such as plants,animals and humans co-exist in this world. So naturally that includes you and me. Yes,we are all members of an ecosystem!2 .There are different kinds of ecosystems depending on the type of surface or environ-ment. Most are naturally made such as the ocean or lake and the desert or rainforest.Some are man-made or artificial to encourage co-habitation（同居）between living and non-living things in a monitored environment,such as a zoo or garden.3 .Plants make up the biggest group of biological creatures within an ecosystem,and that's because they are the natural food producers for everyone. Plants raised in the earth need air and collect sunlight to help them grow. When they grow,the plants and its fruits or flowers eventually become a source of food to animals,microorganisms（微生物）and even hu- mans,of course. Food is then converted to energy for the rest of us to function,and this hap-pens in a never-ending cycle until the living creatures die and break up back in the earth.4 .Ecosystems are the basis of survival for all living things.We depend on plants and ani-mals for food. In order for us to exist,we need to grow and care about other organisms. We also need to care for the non-living things within our environment like our air and water so we can continue living as a population. Since plants,animals and humans are all of various species（物种）,we all play a role in maintaining the ecosystem.5 .To preserve our ecosystems,we should stop using too much energy,which happens when we consume more than our share of resources. Humans should not disturb the natural habitat（栖息地）of plants and animals,and allow them to grow healthily for the cycle to con-tinue. Too many people in a habitat can mean displacement（搬迁）: imagine being thrown out of your home because there is no more space for everyone. Worse,overpopulation can also ru- in the environment and cause destruction of existing plants and animals.Plants,animals and humans are all effective in______.A: our share of resourcesB: a biological creatureC: a given areaD: the maintenance of the ecosystemE: the source of foodF: various species

We can make mistakes at any age.Some mistakes we make are about money.But most mistakes?are about people."Did Jerry really care when I broke up with Helen?When I got that great job,did Jim really feel good about it,as a friend?Or did he envy my luck?"When we look back,doubts?like these can make us feel bad.But when we look back,it′s too late.
Why do we go wrong about our friends or our enemies?Sometimes what people say hides their?real meaning.And if we don′t really listen closely we miss the feeling behind the words.Suppose?someone tells you,"You′re a lucky dog."That′s being friendly.But"lucky dog"?There′s a bit?of envy in those words.Maybe he doesn′t see it himself.But bringing in the"dog"puts you down a?little.What he may be saying is that he doesn′t think you deserve your luck.
"Just think of all the things you have to be thankful for"is another noise that says one thing and?means another.It could mean that the speaker is trying to get you to see your problem as part of your life as a whole.But is be?Wrapped up in this phrase is the thought that your problem isn′t important.It′s telling you to think of all the starving people in the world when you haven′t got a date for Saturday night.How can you tell the real meaning behind someone′s words?One way is to take a good look at?the person talking.Do his words fit the way he looks?Does what he says agree with the tone of?voice?His posture?The look in his eyes?Stop and think.The minute you spend thinking about the?real meaning of what people say to you may save another mistake.
According to the author′,the reason why we go wrong about our friends is thatA.we fail to listen carefully when they talk
B.people tend to be annoyed when we check what they say
C.people usually state one thing but mean another

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.Even if we want to make some changes to help the environment,we can do nothing.A: RightB:WrongC: Not mentioned

Some Things We Know About LanguageMany things about language are a mystery,and many will always remain so.But some things we do know.First , we know that all human beings have a language of some sort.There is no race（种族）of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one another.Furthermore,in historical times,there has never been a race of men without a language. Second,there is no such thing as a primitive（原始的）language.There are many people whose cultures are undeveloped,who are,as we say,uncivilized,but the languages they speak are not primitive.In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood;indeed,the direct contrary has often been stated.Popular ideas of the language of the American Indians will illustrate.Many people have supposed that the Indians communicated in a very primitive system of noises.Study has proved this to be nonsense.There are,or were, hundreds of American Indian languages,and all of them turn out to be very complicated and very old.They are certainly different from the languages that most of us are familiar with,but they are no more primitive than English and Greek.A third thing we know about language is that all languages are perfectly adequate.That is,each one is a perfect means of expressing the culture of the people who speak the language. Finally,we know that language changes.It is natural and normal for language to change;the only languages which do not change are the dead ones.This is easy to understand if we look backward in time. Change goes on in all aspects of language.Grammatical features change as do speech sounds,and changes in vocabulary are sometimes very extensive and may occur very rapidly.Vocabulary is the least stable part of any language.According to the third paragraph,the author thinks that______.A:there exist some primitive languages in the worldB:there are many people who don't have a languageC:no languages in the world haven't been well developedD:there are some languages we know having little complexities

Some Things We Know About LanguageMany things about language are a mystery,and many will always remain so.But some things we do know.First , we know that all human beings have a language of some sort.There is no race（种族）of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one another.Furthermore,in historical times,there has never been a race of men without a language. Second,there is no such thing as a primitive（原始的）language.There are many people whose cultures are undeveloped,who are,as we say,uncivilized,but the languages they speak are not primitive.In all known languages we can see complexities that must have been tens of thousands of years in developing.
