Every year there are changes in climate in different parts of the world.Some of these changes are due to natural causes.However,some climate changes are caused by air pollution and these changes may increase.

If the pollution affects the level of carbon dioxide in the atmosphere,the results are likely to be serious.There is only a small part of carbon dioxide in the atmosphere.But it has an important function in keeping the balance between radiation from the sun entering the atmosphere and radiation leaving the Earth.Some of the radiation is absorbed by the Earth and some is radiated back into the atmosphere.The carbon dioxide in the atmosphere prevents some of the radiation from leaving the atmosphere.Thus the heat remains in the atmosphere and carbon dioxide helps to prevent the temperature of the Earth from falling.

If the proportion(比例)of carbon dioxide in the atmosphere is increased as a result of air pollution,the temperature of the atmosphere may rise.This might cause the ice in the North and South to melt.If this happened,the sea level could rise and parts of the Earth would be flooded.This is not quite likely but the possibility exists.

There is also a fairly strong possibility that the dust level in the atmosphere will rise as a result of industrial pollution.This dust pollution will reflect sunlight back onto space.If this happens,less sunlight will reach the Earth and the temperature will fall.

Another danger comes from the destruction(破坏)of the Earth’s vegetation(植物)such as the forest of Brazil,which is being cleared away for farmland and cities.Trees use carbon dioxide and their destruction may upset the balance of carbon dioxide in the atmosphere.

【1】The main purpose of the passage is to tell us that .

A.the climate of the earth is always changing

B.air pollution has greatly affected the climate of the world

C.carbon dioxide has something to do with climate changes

D.the climate of the world is subjected to(使受到)dangers from air pollution

【2】From this passage we learn that carbon dioxide .

A.helps to prevent the temperature of the Earth from rising

B.keeps much of the sun’s radiation from entering the atmosphere

C.plays an important part in keeping the balance of the temperature of the Earth

D.is one of natural causes of climate changes

【3】Judging from this passage,if the level of carbon dioxide in the atmosphere went down,the temperature of the Earth would .

A.become higher B.either rise or fall

C.become lower D.neither rise nor fall

【4】Which of the following is not the possible serious outcome if air pollution is related to climate changes?

A.Parts of the Earth would be flooded one day.

B.More sunlight would reach the Earth.

C.The temperature of the Earth might rise.

D.The Earth’s vegetation might be destroyed.

【题目】Indoor Plants

As with any house guests，indoor plants require a certain amount of basic，regular attention if they are going to feel at home. The first consideration when purchasing plants is to make reasonably sure that they are suitable for the condition in which they are going to be housed.

A general rule for most plans being brought indoors for the first time is to ensure that they have reasonable temperature of not less than 60 degrees Fahrenheit，a position out of cold air，safe from pets and not exposed to strong sunlight.

Plants love company. When plants are growing together，they create an atmosphere of damp around themselves which is far more beneficial than hot dry conditions. A group of plants will also present a more pleasing picture and provide an opportunity for a creative arrangement. There is no secret to this. Just rely on your natural feeling for harmony.

Watering and feeding plants are probably the two areas of care that are the least well understood，but，again，if you follow a few simple rules，your plants should do well. Cold Slightly warm water is therefore the answer. It is usually better to pour water on to the soil on the surface of the pot rather than put the water into the pot holder at the bottom. Avoid giving small amount of water at regular intervals- it is much better to wet the soil right through the pot in one go and then to allow it to dry noticeably before giving it a further watering.

The majority of indoor plants will be in active growth from March until October，and during this time，the established ones will benefit from regular feeding. This may mean feeding with a weak liquid fertilizer(肥料) at each watering or at intervals of a week or ten days with fertilizer at a standard strength. It is important，however，to ensure that plants are not fed when growth is inactive，when the soil in the pot is dry，or too soon after the plants has been potted up.

【1】In Paragraph 2，the author mainly tells us to___________.

A． but plants that help clean indoor air

B． create a new environment with plants

C． put plants on the sunny side of the room

D． make sure of suitable conditions for plants

【2】What’s the benefit of plants growing together?

A． It provides owners good company.

B． It helps the air around them slightly wet.

C． It makes it convenient to look after them.

D． It allows owners to draw a pleasant picture.

【3】While watering the plants，what should we remember to do?

A． Use water that is a little warm.

B． Pour the water into the pot holder.

C． Give small amount of water at one time.

D． Consider further watering in dry weather.

【4】What is the best time to feed the plants?

A． When the soil is dry.

B． When their growth is active.

C． When the temperature is high.

D． When they have just been planted.

【题目】阅读理解。

When I was in college,I was always very passionate(热情的)about music and I was proud to be a member of our band.However,I almost gave up because of my fear of playing solos(独奏).

One day two years ago my director informed me that he wanted me to be the featured soloist in a piece of music.Of course I was terrified,but he encouraged me that everything would be OK,and that he believed me and knew that I could do it.Up until four days before the concert,I could not make it through the solo.I would always seem to get discouraged before I played it.

I decided to ask my director for help thinking that he would tell me that I didn’t have to do it and that he was still proud of me.All he said was“You just have to believe yourself.”I didn’t think trying his advice would hurt,so I started the next morning differently.Instead of wondering how I could mess up,I imagined myself playing through my solo with confidence and I kept on telling myself that I could do it.

The strange thing was...it worked!After that day I played the solo without any mistake.When the big concert came,although I was a little nervous,I knew that I could do this.I didn’t know what was going to happen,but I realized that the only person that was holding me back from being my best,was myself.I believed myself.I thought things would go a little more differently than they had in the past.Of course,I played the solo wonderfully and I gained acclamation from all the audience.

We already know the fastest,least expensive way to slow down climate change:use less energy.With a little effort,and not much money,most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

Not long ago,my wife,PJ,and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change.Scientists have reported recently that the world is heating up even faster than predicted only a few years ago,and that the consequences(后果)could be severe if we don’t keep reducing emission(排放)of carbon dioxide(CO2)and other greenhouse gases that are trapping heat in our atmosphere.

We decided to try an experiment.For one month we recorded our personal emission of CO2.We wanted to see how much we could cut back,so we went on a strict diet.The average US household produces about 150 pounds of CO2 a day by doing common things like turning on air conditioning or driving cars.That’s more than twice the European average and almost five times the global average,mostly because Americans drive more and have bigger houses.But how much should we try to reduce?

For an answer,I checked with Tim Flannery,author of The Weather Makers:How Man Is Changing the Climate and What It Means for Life on Earth.In his book,he had challenged readers to make deep cuts in personal emission to keep the world from reaching extremely important tipping points,such as the melting(融化) of the ice sheets in Greenland or West Antarctica.“To stay below that point,we need to reduce CO2 emission by 80 percent,”he said.

Good advice,I thought.I’d opened our bedroom windows to let in the wind.We’d gotten so used to keeping our air-conditioning going around the clock.I’d almost forgotten the windows even opened.We should not let this happen again.It’s time for us to change our habits if necessary.

【1】Why did the author and his wife try a new diet?

A.To take special kinds of food.

B.To respond to climate change.

C.To lose weight.

D.To improve their health.

【2】The underlined words“tipping points”most probably refer to “ ”.

A.freezing points B.burning points

C.melting points D.boiling points

【3】According to the passage,Tim Flannery .

A.made deep cuts in his personal emission of CO2

B.wrote a book about the climate changes

C.succeeded in reducing CO2 emission by 80 percent

D.was an author popular among readers

【4】Which of the following would be the best title for this passage?

A.Saving Energy Starts at Home

B.Changing Our Habits Begins at Work

C.Changing Climate Sounds Reasonable

D.Reducing Emission of CO2 Proves Difficult
