Language is a way to communicate with each other. We started to learn language when we were born. However, people are used to speaking their native language, so immigrants are having many problems between the first generation and the second generation because they don’t have the same native language. Also, the second generation is losing their identity. Especially in America, there are many immigrants that came from different countries to succeed in the States.  Because they suffer in lots of areas such as getting a job and trying to speak English, they want their children to speak English, not only at school, but also at home in order to be more successful. Because of this situation, their children are losing their identity and, even more, they are ignoring their parents whose English is not very good.    

I think most immigrants are trying to preserve their native language in their new country, but this doesn’t help very much in getting a good job. My aunt taught Korean to her children not to help hem succeed in the U.S. she did so, hopefully, to help them establish a Korean identity. Though the second generation was born in the new country, they often get confused about their identity because they look different from others, and also, if they visit their parents’ country, they will probably feel different from other people there too. My cousins told me that when they visited Korea a few years ago, they felt different from other Koreans. They could even feel it just strolling around the street because they wore different clothes and walked differently.

We must realize that language is important and valuable for many reasons. Immigrants should make an effort not to be ignored by their children understand their background by teaching them the parents’ language. This is very important, not only for the harmony of the family, but also in helping the second generation establish their identity. 

According to the text, what is the problem of the first generation immigrants?

A. They have lost their identity.

B. Their children are losing their identity.

C. Their children speak different languages.

D. They cannot speak their native language.

My aunt taught her children Korean____.

A. so that they knew they were of Korean origin

B. so that they would be more successful in the U.S.

C. because she didn’t want them to speak English

D. because she wanted them to respect her

The writer’s cousins felt different in their parents’ country because they____.

A. had never been there before        B. behaved quite differently

C. couldn’t understand the language    D. had different facial appearance

According to the text, the native language is important and valuable to immigrants in that____.

A. it gives them self-confidence and better chance

B. t makes the second generation love motherland

C. it helps the second generation to understand their parents

D. it strengthens the family ties and reminds them of their identity (BCABD)

Every people has its own way of saying things, its own special expressions. Many everyday American expressions are on colors.

Red is a hot color. Americans often use it to express heat. They may say they are red hot about something unfair. When they are red hot they are very angry about something. The small hot tasting peppers found in many Mexican foods are called red hots for their color and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz.

Pink is a lighter kind of red. People sometimes say they are in the pick when they are in good health. The expression was first used in America at the beginning of the twentieth century. It probably comes from the fact that many babies are born with a nice pink color that shows that they are in good health.

Blue is a cool color. The traditional blues music in the United States is the opposite of red hot music. Blues is slow, sad and soulful. Duke Ellington and his orchestra recorded a famous song – Mood Indigo – about the deep blue color, indigo. In the words of the song: “You ain’t been blue till you’ve had that Mood Indigo.” Someone who is blue is very sad.

The color green is natural for trees and grass. But it is an unnatural color for humans. A person who has a sick feeling stomach may say she feels a little green. A passenger on a boat who is feeling very sick from high waves may look very green.

Sometimes a person may be upset because he does not have something as nice as a friend has, like a fast new car. That person may say he is green with envy. Some people are green with envy because a friend has more dollars or greenbacks. Dollars are called greenbacks because that is the color of the back side of the paper money.

The color black is used often in expressions. People describe a day in which everything goes wrong as a black day. The date of a major tragedy is remembered as a black day. A blacklist is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations.

1.If you had your wallet stolen while doing some shopping, you may call it        .

2.Suppose a Mr. Brown says he is very happy because his three children are all in the pink, this means all his children are         .

3.When she got home and found nothing had been done by her husband, Jane was really      .

The quality of water supply in southern Beijing has been improving in recent years, an official said.
In addition to improvements in the network of pipes, the government has been upgrading three recycled water plants in the south of the capital, said Zhao Lei, spokesman for the Beijing Municipal Commission of Development and Reform.
"The transformation of the three plants has increased the recycled water processing capacity by 160,000 cubic meters per day," he said.
In addition, the city is also speeding up the construction of sewage treatment plants to further recycle the sewage, Zhao said.
Zhang Xiang, a researcher from Nature University, an environmental protection NGO in Beijing, said recycled water use should be promoted, especially in water-scarce cities such as Beijing.
Setting up more recycled water plants in the capital will not only promote efficient water use, but also reduce costs because recycling water is much cheaper than transferring it over long distances, he said.
According to the Beijing Water Authority, the capital will set up 46 more recycled water plants citywide in the next three years while upgrading 20 sewage treatment plants.
The treatment rate of domestic sewage in downtown Beijing will reach 98 percent by the end of 2015, it said.
The capital's recycled water is mainly used for industry, landscaping and cleaning, Zhang said.
Many new communities in southern Beijing are equipped with a network to recycle water.
In the past, people were not enthusiastic about using recycled water. However, as the government has boosted the quality of recycled water and set up more recycled water plants, more residents are gradually accepting it.
Residents in southern Beijing will also enjoy more clean energy, as the government will replace traditional coal-burning stoves with electric radiators as part of a three-year plan to develop southern Beijing from 2013 to 2015.
Since 2010, Beijing has taken measures to develop its southern areas. Earlier efforts have seen the region, which used to rely heavily on low-end industries such as cement factories and small coal mines, being turned into a bustling commercial center and home to many educational institutions.
【小题1】This passage may appear in ________ section.

Look closely at ,your hands-are they clean? It doesn't matter how many times you was  your hands. They're still crowded with microbes, which are also called "germs" or "bacteria". Microbes are everywhere. But don't worry-most microbes don't harm you. and many actually help you stay alive.

Now,  scientists say the microbes that live on our hands could be used in a surprising way: fighting crime.

When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal.  But according to a recent study, investigators could even use microbes to help break a criminal case.

Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody's hand is unique-much like one's fingerprint.

The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find.  And policemen use forensics such as studying fingerprints to identify the criminal.

"Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists.

"You can't sterilize(为……杀菌) a surface just by wiping it off. "

His team compared the bacteria on the hands of 273 people with the bacteria found on each person's computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son's hands matched the mix of microbes on that person's keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards.

But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful. 

Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool．

　　A scientist who developed a way to calculate(计算) how much water is used in the produciton of anything form a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.
　　Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water(虚拟水)",a calculation method that has changed the nature of trade policy and research.
　　Allan has written seven books and published more than 100 papers.
　　The Stockholm International Water Institute said this idea is now embedded(埋藏) in the production of foods and industrial products.The institute said Allan's work had made a big effect on global trade policy and research,especially in water - scarce(缺水) regions.
　　"The improved understanding of trade and water management issues on local,regional and global scales are of the highest value for the successsful and sustainable(可持续的) use of water resources,"it said.
　　"People do not only use water when they drink it or take a shower,"the institute said. "Behind the morning cup of coffee,there are 140 liters of water that was used to grow,produce,package and ship the beans."That is about as much water as a person in England uses on average for all daily drinking and household needs.
　　"For a single hamburger,about 2,400 liters of water are needed.In te USA ,the average person uses nearly 7,000 liters of virtual water every day" It said that was more than three times the average use of a Chinese person.
　　64.Allan was awarded the prize because ______.
　　　A.he wrote seven books on trade policy
　　　B.he published more than 100 papers on water management
