树和环境有什么关系:
1.树木能调节气候,保持生态平衡,树木通过光合作用,吸进二氧化碳,吐出氧气,使空气清洁,新鲜.一亩树林放出的氧气够65人呼吸一辈子.
2.树能防风固沙,涵养水土,还能吸收各种粉尘,一亩树林一年可吸收各种粉尘20-60吨..3.树林能减少噪音污染.40米宽的林带可减弱噪音10-15分贝.噪音的污染对人类的生活、学习、工作、休息等方面都造成了很大的危害,可以说是人们的“敌人”.因此我们更要重视植树造林.噪音还可以使人类在长期的生活中听力减弱、耳聋、变傻,心脏、血压、神经等出现异常.甚至,还能让人在长期的噪音煎熬下死亡.这样树林就能使噪音减小四、五倍.
4.树木的分泌物能杀死细菌.空地每立方米空气中有3,4万个细菌,森林里只有300-400个.
5.树可以减低温度,和提高湿度.30度气温可以降到二十几度左右.

How often one hears children wishing they were grown up, and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.
Youth is a time when there are few tasks to make life difficult. If a child has good parents, he is fed, looked after and loved whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the child—things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is continually being told not to do things, or being punished for what he has done wrong.
When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he words hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.
11. People can experience happiness if they ______.
A. always think of the past and regret it
B. value the present
C. are no longer young
D. become old and have much experience
12. When people were young, they used to ______.
A. be in charge of many business
B. have few things to think about and take on
C. look after their younger sisters and brothers
D. face a lot of difficulties
13. The pains of children lie in the fact that ______.
A. no one helps them make right decisions
B. they are often beaten by their parents
C. they can not be accepted and praised by others
D. they are not allowed to do what they like to do
14. Children are usually happy because ______.
A. old people lose interest in them
B. they are free to do wrong
C. they are familiar with everything going on around them
D. things are new to them
15. Which of the following is NOT needed for a young man to be happy?
A. Hard work. B. Being free from troubles.
C. Wealth. D. Health.

1.C
是这样的,如果这个句子是现在一般时,就是这样的:
They tell us that they have planted three hundred trees by the time the workers get there.
所以如果是过去时,那么每一个时态都变成比原来那个更过去一点的时态.我就是这么理解的.
2.我们在洞旁边的土地上插了一根竿子.
3.传过去
4.空处为 It
把问句改成陈述句是:___It___takes Ann Alice almost an hour to get home.
做的时候问句不容易看清楚短语和结构,用陈述句来做.
5 A as...as才对
B physics是单数
D 是单数!

1.英语的语言习惯与汉语不一样,切不可以汉语的语言习惯来用于英语的口语中.
2.在语法上来说,something 用于肯定句中,anything 用于疑问句和否定句中.在句型转换中更明显:
there is something wrong with him.变一般疑问句:
is there anything wrong with him?但是在希望对方给予肯定回答的时候,something 是可以用于疑问句中的.如:would you like something to eat?is there something to drink?
3.这个句子考查的是定语从句中that/ which 的用法,进一步说是,考查什么时候只能用that而不能用其他的词.
在先行词前有the only ,the very ,the most,the first...(有许多情况在此就不一一列出了).此题就是因为有the only 修饰thing ,所以一定要用that.
4.这道题怎么也不应该选c.c项是物主代词啊.其实这道题所应有的混淆项应该是it's.这里的it是形式宾语这正的宾语是to learn the english well.而important是宾语的补足语.这种情况千万千万不要用it's!
