For years scientists have been worried about the effects of air pollution on the earth’s natural conditions.Some believe the air inside many houses may be more dangerous than the air outside.It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired,to suffer eye pain,headache and other problems.Some pollutants(污染物质) can cause breathing disorders,diseases of blood and even cancer.Most scientists agree that every modern house has some kind of indoor pollution.

People have paid more attention to the problem now.It is said that when builders began making houses and offices,they did not waste energy.To do this they built buildings that limited the flow of air between inside and outside.They also began using man-made building materials.These materials are now known to let out harmful gases.

As the problem became more serious,scientists began searching for a way to deal with it.They discovered a natural pollution control system for buildinggreen plants.Scientists do not really know how plants control air pollution.They believe that a plant’s leaves absorb(吸收;吸引) or take in the pollutants.In exchange the plant lets out oxygen through its leaves and small organizations on its roots.Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space.Studies of different plants show that each absorbs different chemicals.So the most effective(有效的) way to clean the air is to use different kinds of plants.Having green plants inside your house can make it prettier and more healthy place.

No one can believe that the over 6 300-kilometer long Great Wall might disappear some day. Believe it or not, the Great Wall is being destroyed by people. Less than 20 percent of the Great Wall built in the Ming Dynasty is still perfect, but about 80 percent is in danger. The Great Wall can be called “great” mostly because of its amazing length. But we should realize that the length was made up of one brick at a time. If we do nothing to save the Great Wall, it will become a series of separate wasteland rather than a historic site.

The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2 000 years. It began in the rule of China’s first emperor, Qin Shihuang of the Qin Dynasty(221 BC~206 BC), and lasted into the Ming Dynasty. The parts built before the Ming Dynasty have nearly disappeared. People are familiar with sections such as Badaling in Beijing and Jiayuguan Pass in Gansu because they have been open to tourists for many years. But those sections far away from the public eyes have been almost forgotten.

Few local people knew the 3-meter-high walls made of earth and stones beside them are part of the Great Wall. The lack of knowledge is considered as one of the main reasons behind human.

The bricks on the Great Wall are carried off by countryside people to build their houses, sheep corral(畜栏) and pigsties(猪圈). Some were taken away to build roads. Bricks carved with people’s names are put away as remembrance. Rubbish is spread over the battlements(城垛). The bricks can be sold for 15 yuan per tractor load. Those who destroyed and are destroying the Great Wall know its name, but are not clear about its cultural meaning. It will take a long time to let them know this. The local farmers not only carried off the body of the Wall but dug out the entire base.

It is necessary to protect the Great Wall. First of all, the officials should be aware of the importance of the Great Wall. Young Chinese should know more about the nation’s great civilization(文明)and learn to love it.

A. that are too difficult to understand

B. nobody can watch

C. that are too far to been seen

D. that are not well known to the public

4.What’s the main reason of the Great Wall’s being destroyed

A. The local people are short of culture knowledge.

London is great .It's great .Rome and Paris were fine places ,but I knew as soon as we landed in London ,this was the finest of the three.

There are only two small things which I don't like about London . First of all, everyone speaks English here. I had so much fun in Rome and Paris . There I could speak in foreign languages. In words ,I made a lot of friends that way .But here everybody can understand me. I don't have any reason to start up a conversation with a stranger . And speaking of restaurants that is the other problem with London . The food here is no good at all! I haven't had one good meal in the three days we've been here.

Since you asked me to write to you about everything I learned on this trip ,here is what I've learned about London.

London's population of eleven million makes it the second largest city in the world .It is bigger than New York but not as big as Tokyo .London is twice the size of New York .It has an area of 620 square miles!

The Thames River runs right through the center of the city .Someone once called the Thames “liquid history”.It is a very good name. Dozens of armies have crossed it over the past few thousand years .One of the first was the army of Julius Caesar two thousand years ago .And most recentlyMr .and Mrs. Gill.

So far I have only had time to visit one neighborhood .It is called Bloomsbury .In fact there is a group of writers known as the Bloomsbury Group. It got its name because so many of them lived there. Virginia Woolf was one of them .I know how much you like her novels.

Baker Street is also part of Bloomsbury .Do you remember who once lived on Baker Street When I asked Bob this question, he answered,“a man who baked bread ,right ” Sherlock Holmes ,of course ,I won't have time to find his address .Maybe you will when you come.

Building Trust in a Relationship Again

Trust (信任)is a learned behavior(习得行为) that we gain from past experiences(以往经历). 1.Trust is a risk.But you can’t be successful when there’s a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.

Unfortunately,we’ve all been victims of betrayal(背信).Whether we’ve been stolen from,lied被欺骗 to,misled被误导,or cheated on被哄骗,there are different levels of losing trust.Sometimes people simply can’t trust anymore(有时候人们就是不能再信任别人). 2. It’s understandable(可理解的),but if you’re willing to build trust in a relationship(人际关系) again,we have some steps you can take to get you there.

3. Having confidence in yourself will help you make better choices because you can see what the best outcome结果 would be for your well-being幸福.

4.If you’ve been betrayed(如果你遭遇了背叛),you are the victim(受害者) of your circumstance(客观环境).But there’s a difference between being a victim and living with a “victim mentality”(“受害者的心态”).At some point in all of our lives,we’ll have our trust tested or violated. 被破坏

You didn’t lose “everything”.Once trust is lost,what is left? Instead of looking at the situation from this hopeless angle角度,look at everything you still have and be thankful for all of the good in your life.5.Instead,it’s a healthy way to work through the experience to allow room余地 for positive growth and forgiveness(宽恕).

A.Learn to really trust yourself.

B.It is putting confidence in someone(对某人寄托信任).

C.Stop regarding yourself as the victim.

D.Remember that you can expect the best in return.

AC.This knowledge carries over in their attitude toward their future relationships.

AD.Seeing the positive(积极的) side of things doesn’t mean you’re ignoring(忽视) what happened.
