My hometown used to be a clean place.The estate is full of greeneries and no one litters.Ever since some stupid clowns said that they discovered an old emperor tomb in the estate.Many cheapskates also came to dig holes in my hometown.Now my hometown has become a place with chopped trees,the ground with many pot holes,eveywhere is with litters and shit is everywhere.

基因表达可以由结构的变化来调节.对于苍蝇的眼睛来说,眼睛颜色依赖于基因“白”.就算是野生品种,基因“白”也是存在的,而且所有表达“白”的DNA序列都在,眼睛颜色的发育可以通过基因转录被抑制.举出两个例子来说明分子结构的变化如何能够改变基因“白”的表达.一个变化应该改变基因“白”的转录,另一个应该包括“白”的转录后调节.两种情况都不会改变“白”的DNA编码.两种情况下,请分别给出基因“白”染色质、“白”转录活动,以及“白”转录物的增长.

In the last fifty to one hundred years, all around China, in rich and poor areas, the traditional family life is undergoing extreme changes, such as smaller nuclear family, the changes of father as a breadwinner and mother as housewife, rising divorce rates, bias on the sex of child, etc. some of them are good for the development of the society while others still need to be guided with the ethic and moral education.
Having bias on the sex of child is a nagative view hold by most old people in countryside, who prefer boys to girls for they think only boys are the offspring of their own family and girls would be the member of their husbands'.In the past years boys could get more love and education chances than girls. With the development of the society, more and more people abandon the illogical bias and treat boys and girls the same. More girls can get the chance to receive education and show their talent in every field. All the facts have proven that boys and girls can shoulder the same family and social responsibility.
Rising divorce rates,in my opinion, is not a good thing for the stablity of the society. In the past people felt deeply ashamed for divorce and there were fewer people who wanted to divorce. Nowaways modern people have open mind and casual attitude on marriage and some of them don't consider it seriously,which lead to more and more rising divorce rates. This is not a good trend for a stable and rising country like China. We need to strenthen the moral education about family value and help the younger generation establish serious and heathy attitude toward life and marriage.
In such a quickly developed society, Many changes happen every day. We should be aware of some unhealthy changes in our country and try to improve them. Actually most of the changes are for the good of human being and society, because we can see the great prosperity and improvement! We believe tomorrow will be different and better!

Heated ,water changes into steam.
受热以后,水变成了蒸汽.
在这里heated并不是过去式,而是过去分词,表示水被加热,是被动语态.

Now I will show some tips about changes in China to you:
1.x05In China's shift to a market economy,one key marriage player has been phased out:the work-unit boss.For 50 years,the boss was a de facto sergeant inside state-run enterprises.He or she policed behavior among the sexes,assisted with family problems,often helped set up single women approaching the unofficial "spinster" age of 30,and approved all matches.
2.x05"If you turned 28 and were still single,the danwei manager [or boss] would step in and help," says Yu Jiang,a single 27-year-old who recently quit a US-China joint venture.Now the work-unit boss no longer approves marriages; the position is disappearing along with state-run businesses.
3.x05Weddings in pre-1980 China were simple,short,and cheap.Today,70 percent of the weddings done by Purple House,a Beijing agency,are Western-style - vows,white dresses,churches,receptions,says Shi Yu.Mr.Yu is Purple House's "master of ceremonies." Weddings used to cost $40.Now they easily run $4,000 and are a status symbol.
4.x05Once married,Chinese couples are no longer choosing to live with parents at home,a huge change.Some 60 to 70 percent of couples no longer live with parents,and in the reporting for this article,virtually no young Chinese said they would live at home if they could afford not to."No way," says Jun Yaolin,who was married two years ago."We will fight." One counter-trend is to live a "bowl of soup" distance away - move to within a few blocks.This neatly supplements another new trend:full-time care of children by grandparents.
5.x05Divorce,once seen as antisocial,is now high by Chinese standards and increases yearly.In Shanghai in 2001,1 in 3 marriages failed,according to Xinhua news agency.
6.x05The maturing of the one-child policy,combined with the ability of couples to buy their own apartments,is creating its own "empty nest" condition.This means that older people are starting to experience an often terrible new loneliness.China is still a country with respect for elders.Yet a public-service ad on Chinese TV shows an elderly lady cooking all day.As she sets the table for dinner,the phone calls come one by one:"I can't make it.Can I come tomorrow?" The ad ends with a solitary figure sitting at a table of food - and the words,"Don't forget your parents."
7.x05"The traditional family has changed,become diluted,atomized," says Dong Zhiying,a scholar at the Chinese Academy of Social Sciences (CASS) in Beijing."It used to be assumed that kids would take care of parents.Now it no longer is.In the past,older people in the family were dominant.Young people had no choice but to respect them.Parents' authority was based on money and power; if you don't respect them,you lose favor.”
8.x05"Today,the intellectual and market development in China has come quickly,and transformed the family.Young people aren't worshipping elders.They can rely on their own ability - go to university,be independent,make their own choices."

一个线圈磁通量从4.5T*m2变到0经过0.1s时间,求平均感应电动势
E=4.5/0.1=45V

It seems that the farming in the U.S.has changed dramatically from 1940s to 1980s.The population of farmer has decreased from 32million to 6 million only while the average farm size increased almost 3 times from 170 acres to 450 acreas.Another notable change is that the number of farms has also dropped to 1/3 of 1940s figure.
There maybe two main reasons that why the dramatic change has taken place in the U.S.First of all,the develpment of high-technology has modified farming population generally.The more machines used,the less mankinds needed.Secondly,people are tends to follow a more colorful and exciting life style so they have flowed into cities.
In my point of view,the U.S.is still a country with a great deal of agricultual products export.Although the trends indicated here are not very pleasant,the decrease in farming population and farms will not influence structure of American economy in a considerable way.

此处change作名词解及改变s是复数形式的意思

Dietary Changes and Health CareAs is shown in the graph, China's food distribution has taken great changes from 1960's to 1990's According to this statistics of cereals, vegetable, meat, and fruits, the number of those who eat rice, flour or vegetable has greatly decreased in the past four decades. In contrast of this the number of those who eat oil or meat has sharply increased. From such dietary changes, we can perceive the rapid improvement of our people' s living standard.Why does this improvement occur? The direct reason is the fact that the Chinese people have attached much importance to their health care. Nationally, China's economic growth is booming, and more people are getting richer. Individually, everyone's consumption of food is increasingly varied. In particular, most of people are reluctant to eat much vegetable, but much meat and oil in their diets.In my view, the changes of China's dietary distribution seem to be both positive and negative. The positive aspect is that China' s economical growth has given rise to the higher level of dietary standard, with most of people living rich and happy. But the negative aspect is that, I'm afraid, less eating vegetable will lead to poorer health, such as lacking vitamin nutrients in one's body. Therefore, we think it necessary for the Chinese to be aware of the balanced diets: Lots of vegetable and meat, which may gain us healthier bodies in the new century.

In the past,the roads were narrow．The living conditions were poor．people kept in touch with their friends and relativesfar away mainly by letter or telegram．Some children can't get a good education．
Now,ChongQing has developed rapidly．There are many ring roads．people living conditions have improved a lot．Children can get a good education．what's more,communications are becoming easier and quicker．
I believe ChongQing has become more and more beautiful．I think itis important to remember the past,live in the present and dream about the future．

围绕责任感或者幽默感谈谈都不错吧
比如说小时候没责任感,然后妈妈得了次病结果我就知道要去做事了,有了责任感.
又说小时候也不知道笑话能有什么用,结果成长后发现跟同学谈话讲几个笑话让大家都跟我交朋友了,我也就培养了幽默感了.
这两个品质可以说是万能的啊

if引导的一般条件句.
could在这里并不是虚拟语气,而是表示一种可能性.

Great changes have taken place in people's life in the past 20 years. In the past people kept in touch with friends mainly by sending letters. They would listen to the radio for news and other information. Children used to go to school by bike. A big family had to share small rooms.
Now people can talk to others by telephone or on the Internet at home. When they are free, they will watch the news and other programs on TV. And children usually go to school by bus. More and more people live in big and bright aprtments with several rooms. Some families are rich enough to send their childrento study abroad.
In a word ,people live better than before .

社会结构的改变可能会间接地影响到青少年犯罪率.比如：社会经济的改变总的来说致使年轻人的就业机会越来越少,失业率越来越高,使得富有成就性的就业越来越难.
make是谓语 后面的应该是句子做宾语吧（不好意思 我语法较差,特别是句子成分这些）

选C (ability of doing sth 表示“做某事的能力”,也可以用ability to do sth,意思一样；pass on to 中的to 是介词,后面要加名词,所以用V-ing形式） 哦.

只有当我的记性变好之后这些改变才能发生.
