She has two big eyes that seem to be able to speak.

你这段写的很好,只有三个细小的地方,第一个分句最好加一个novel,后面的which like是不对的,缺少宾语,你要么省略which is,用just like这样的,或者直接用which is.最后一句could后面直接跟原形,不能用to do形式,要么是could dreams be achieved,或者could dreams come true.下面是我改好的段落：
In John Steinbeck’s novel, Of Mice and Men, dreams are the source of power and hope for
homeless workers when their futures seem dim. Life without dreams is meaningless just like the walking dead. But could dreams come true?

I am Tina.
Just a normal and ordinary girl.
But I have a big big dream which is to go abroad for further study and become an English teacher.
The realization of this big dream needs constant efforts and perspiration.
Because I am still so young that I can't even decide what kind of road I should take and what kind of fate I will face.All I can do is to plan and try hard while keep studying.In order to study abroad,the first condition is to have excellent English and communication skills.So from now on,I must learn English knowledge quite seriously by my heart,through which I should firmly grasp the relevant knowledge so that I will be capable enough to go abroad for further study after I grow up.Otherwise,I can't even simply communicate with people in Britain,which will definitely be the laughing stock for foreigners and become the shame of China?As my first step in my life,I want to learn English well and go abroad to study.
But why do I want to be an English teacher abroad?That's because I want to let foreigners know that Chinese has such capability that we can do as good as foreigners,even better!So foreigners won't underestimate Chinese!After I come back from abroad,I will let more Chinese to experience the happiness while learning English.
For this dream,I keep trying and working hard day by day,waiting for the day when my dream will come true!

你的这个构想几乎不算是科幻了,也用不了几百年,空气质量就会大大降低.至于空气质量降低会引起地球毁灭这个假设似乎值得商榷.一个孩子用身体净化了空气拯救了地球这个构想相当悬,事实上,我们现在就已经能够净化空气了,只是成本比较高,难以推广开来.

可能在所有灾难中,最可怕的就是人类某天永远消失在宇宙中.物理学家已对物理宇宙进行研究,并发现有多种迷人物质与此有关.比如说,被科学家称为“虚粒子”的粒子就可以出现在任何地方,也可以再次消失.假如整个宇宙是由某种虚粒子组成,那么将会发生什么事情?一种相似理论就认为在统治宇宙的物理常数里就有一种突变.我们目前所观察到的物理常数可以决定重力大小和核力强弱,这些可能都是由一种真空亚稳态事件所创造产生的.想象一下,我们的宇宙现在是一个球体,它只能在某种高度上生存.现在这个球体滚下山,突然遭到撞击,以一个偏角停在了中间.尽管宇宙(球体)现在看起来是在一个很稳定的位置,但事实上,它是不稳定的.只要再一次撞击它,它就能滚下山,滚到我们宇宙能够生存的高度以下.那么宇宙就可能被毁灭,一些新的物理定律可能会出现.但我们却不知道是什么撞击了宇宙.

pring is tht best season of the year.The weather gets warmer and warmer.My clas i'amates and I took a one-day sightseeing around our city.The scene was pretty.But when we saw the rivers along our city,I felt very sorry,and thoughit a lot.
With the development of modern agriculture and industry,more and more waste water is being poured into rivers.It has caused serious pollution.The river is becoming so dirty that no living things can live in it.The river is giving off a terrible smell.
We make an urgent appeal that measures should be taken to cope with the situation.Our government should start building various facilities such as sewage treatment!plant and encourage scientists to work out more and better ways to reduce the pollution of water.
Water is tho source of our lives.It is very important to protect water.

This is Bill White with with the VOA Special English Environment Report.
We usually think of (1)pollution as a harmful waste (2)substance that threatens the air and water.But some people have become (3)concerned about another kind of pollution.It can be everywhere,depending on the time of day.And it is not thought of as a substance.It is light.
The idea of light pollution has developed with the increase of lights in cities.In many areas,this light makes it difficult or impossible to (4)observe stars and (5)planets in the night sky.In Nineteen-Eighty-Eight,the International Dark-Sky Association formed.This organization wants to reduce light pollution in the night sky.It also (6)urges the effective use of electric lighting.
There are a number of reasons why light pollution is important.One has become clear at the Mount Wilson Observatory near Los Angeles,California.Mount Wilson Observatory was home to the largest (7)telescopes in the world during the first half of the Nineteen-Hundreds.
During that period,Los Angeles grew to become one of America's biggest cities.
Today,light from Los Angeles makes the night sky above Mount Wilson very bright.It is no longer an important research center because of light pollution.
Light pollution threatens to reduce the scientific value of research telescopes in other important observatories.They include Lick Observatory near San Jose,California and Yerkes Observatory near Chicago,Illinois.
Light pollution is the result of wasted energy.Bright light that shines into the sky is not being used to provide light where it is needed on Earth.Poorly designed lighting causes a great deal of light pollution.Lights that are brighter than necessary also cause light pollution.
Recently,two Italian (8)astronomers and an American (9)environmental scientist created a world map of the night sky.The map shows that North America,Western Europe and Japan have the greatest amount of light pollution.
Most people in America are surprised to find out that they are able to see our own (10)galaxy,The (11)Milky Way,with their own eyes.But about three-fourths of Americans cannot see the Milky Way because of man-made light.

Pollution
As the world is getting more densely populated,pollution presents a severe problem.More people make more waste.All this waste is polluting our surroundings.
Pollution has a bad influence on our life.The air is pollnted by the smoke and fog coming out of the factory chimneys.Plants die for want of fresh air.The river is polluted and the fish are unfit to live.There is noise pollution made by cars and factories,etc,which hurts the ear.
It is high time we did something about pollution.I suggest more trees be planted to keep the air fresh.We should purify the water and make use of the wastes and turn harm into good.
By cur common efforts,we will make a clean and purified environment for life and work.

Write a passage with the words and phrases given:
the problem of pollution,cause,artificial substances,release,waste products,industrial production,consumption of goods,bring it under control,agriculture,chemical substancea.
Environmental Pollution
I read a piece of news recently.It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular.Why?--Fresh air is getting less and less in Japan,and so is it in the U.S.A.
In fact,environmental pollution is a very serious problem the whole world is facing.
it is mainly caused by the waste products released from artificial substances,industrial
production and increased consumption of goods.Bedsides,the use of chemical substances
in agriculture also causes environmental pollution.Look at the sky,you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.
How to change this condition?More and more countries are trying to work out some effective means to bring it under control,but no great success has been made.
5
health,surrounded by,smog,anything but,gases,impurities,absorb,poisonous,try hard,blacked out
We all know that clean air is important to good health.Wherever you go and whatever you do,you are always surrounded by a sea of gases that we call air.If there are impurities in the air,they may be absorbed by our bodies and make us ill.We need clean air,but unfortunately,air pollution is globally present,especially in cities.
Many large cities are anything but pollution-free.Our cities have many factories,which we need to make food,clothing and other things.Every year these factories pour millions upon millions of tons of smog into air.Power plants and houses that burn coal add greatly to air pollution.Besides,there are more cars in cities now.Once out on the streets,they will take in fresh air and replace it with poisonous gases.
Our country is trying hard to prevent and control air pollution.As long as every citizen also realizes its importance and makes join efforts,the day will come soon when people will take in only clean air.Then,the sunlight will no longer be blackened out by smoke and soot.
6
Pollution is harmful to human beings.Polluted water causes many kinds of diseases such as diarrhea,enteritis,etc.And sometimes these diseases even take man鈥檚 life.Dirty air or air-borne garbage causes stinging eyes and running nose.Pollutants are destructive.They cause runs in nylon stockings and crack rubber tires and they eat away at stone and rust iron.
Measures have been taken to control pollution.In recent years,legislative steps have been introduced to control pollution.Rivers are being cleaned.Air is purified,and pollutants are being trapped before they are poured out of chimneys.
However,pollution problems have not been completely solved.Pesticides are widely used almost everywhere.They pollute soil,water and food.They have the power to make our streams fishless and our gardens and woodlands silent and birdless.Some factories are still using air as a dumping place for wastes.Some lakes are still dirty.Quite a few chimneys are still pouring smoke into air and noise pollution remains serious.

解题思路：由于我国水资源地区分布不平衡，为了合理利用水资源，有必要兴建跨流域的调水工程．如引黄济青工程，将黄河水调进青岛市，以解决青岛市供水不足的问题．我国水资源的季节分配不平衡，年际变化大，有必要兴建水库，洪水期蓄水，枯水期放水，以调剂各季节的河流水量．新中国建立后，我国已兴建了大量水库，用于调控水量，提高防洪、抗旱能力，并扩大灌溉面积．

“①发展高新技术产业 ②提高水资源的利用率④实行阶梯式的水价”都有利于节约用水，“③开采地下水”会带来一定的环境问题，从可持续发展的角度看，得不偿失．
故选：C．

1）令g(x)=x+√x²+1>x+|x|>=0
所以f(x)的定义域为R
2）g(-x)=-x+√x²+1=1/[x+√x²+1]=1/g(x)
因此f(-x)=lg g(-x)=lg 1/g(x)=-lg g(x)=-f(x)
因此f(x)为奇函数
3）x>0时,g'(x)=1+x/√x²+1>0,因此g(x)单调增,所以f(x)也单调增.
又因为f(x)为奇函数,所以f(x)在R上都单调增
