2.induce改为induces 句子主语是the cooking而不是meat and vegetables,动词应使用单数。
3.it改为them 因为其先行词为复数名词短语“the meat and vegetables”。
4.√
5.before改为after 根据文意可以推断这里要表达“之后”的意思,使用before不合逻辑。
6.cookers改为cooks cooker厨房用具,cook厨师。
7.chemistry改为chemical chemistry是名词,此处应用其形容词形式修饰名词。
8.achieving改为achieved 此处要修饰changes,应使用achieved,因为changes不能主动“实现”。
9.在know后加about know认识,知道,know about表达“对……有所了解”之意。

第2题：
Directions: Some people think that all university students should study whatever they like. Others believe that they should only be allowed to study subjects that will be useful in the future, such as those related to science and technology. What′s your view about what subject university students should study? You are required to write a composition within 180 words, but no less than 150 words.答案：解析：People have different views about what subject university students should study, whether the one they like or only the one that will be useful in the future. People who believe students should only study subjects that will be useful in the future list several reasons. First, university courses like medicine, engineering and information technology can provide more job opportunities, career progression, better salaries, and therefore an improved quality of life for students who take them. Second, those subjects play the major role in new inventions, economic growth, and the society' s greater future prosperity. As far as I am concerned, university students should be free to choose their preferred subjects. In my opinion, students can study well if the learning content caters to their interest. Besides, the creative thinking patterns behind some theoretical subjects have potential value. In this sense, more students of art, history and philosophy are needed. In conclusion, although it might seem sensible for students to focus only on the most useful subjects, I personally assert that they have the right to study whatever they like. -

问答题Practice 1Directions: You are asked to write in no less than 150 words about the title of Increase of Farmers’ Income. You should study the following chart carefully, then write a composition to:1. describe the changes of farmers’ income in the past three years;2. give at least two possible reasons for the changes.正确答案：
【参考范文】
Increase of Farmers’ Income This chart shows the increase of farmers’ family income in the county from 2006 to 2008. The farmers’ family income in 2006 was 20000 yuan per family. It increased by 50% to 30000 yuan in the year of 2007, and jumped spectacularly to 45000 yuan, increasing by another 50% of the amount of 2007.
From the result it can be seen that the farmers’ family income has increased sharply in the last three years, and they are living a better life now. I think several reasons account for the increase. Firstly, with the rapid development of our country’s economy, our government has paid more and more attention to the development of agriculture. Measures have been taken to encourage agriculture production and to protect the farmers’ interests. Agricultural taxes and other charges have been reduced, more funds have been invested in the development of agricultural projects, and crop prices have been raised. Secondly, thanks to the popularity of science and technology, and better education, many farmers are now using agricultural machinery or even high-tech in farming. Since mechanization and high-tech can help accelerate the increase of the output of agricultural products, farmers can sell more products and make more money.
As the development of the economy goes further on, I think the farmers’ income will continue to increase in the future.解析： 暂无解析 -

Problems with China’s management of our tourist industry;3. Your suggestions on how to improve travel management, especially the travel in big holidays.正确答案：
【参考范文】
Tourist Industry in China With our tourist industry achieving tremendous progress, some serious problems occur accordingly and remain to be solved urgently. For example, Blind building of hotels and tourist resorts around the interesting places causes air and water pollution.
To tackle these problems, My suggestions are as follow. First of all, try our best to update our transportation and communication systems. More convenience in traffic will bring us more income from tourism. Secondly, more places of historical interests and scenery spots are to be explored to let foreign friends see more exciting things than just clay-warriors and horses in Xi’an or Summer Place in Beijing. Thirdly, our food and hotel industry should be greatly pushed forward to attract more foreign guests.
Therefore, I suggest the relative departments launch a campaign to improve the tourism quality. Only when our tourism is attractive enough can we push our country into one of the top tourism countries in the world.解析： 暂无解析 -

问答题Practice 3Directions: For this part, you are allowed 30 minutes to write a composition on the topic Immoral Behavior in Public. You should write at least 120 words but no more than 180 words.正确答案：
【参考范文】
Immoral Behavior in Public To witness immoral behavior in public, one just needs to have a look at the bus stop. There are always lots of people waiting for buses at the bus stop. Few of them stand in line as required. Whenever a bus comes, many people just run to the bus and try to get on in chaos. Many of them push each other in an effort to get on first.
Immoral behavior in public leads to a series of problems. Among the most serious, one is that it may exert a negative effect on our sense of social responsibility. If we allow this kind of immoral behavior to continue, we are ignoring others’ rights and feelings, and in turn, we as well will be disrespected.
To improve this phenomenon is certainly not easy. In view of practical implementation, I propose that society make it clear at all points that people who fail to respect the common good will be seriously punished. Strict policies regarding this should be made to correct this phenomenon as soon as possible.解析：

第10题：
问答题Your class has recently had a discussion about learning a foreign language. For homework, your teacher has asked you to write a composition of no fewer than 120 words, giving your opinion about the following statement: The best way to learn a foreign language is to study it in the country where it is spoken. Please write your composition on the Answer Sheet.正确答案：
The Best Way to Learn a Foreign LanguageWe have had a discussion about whether the best way to learn a foreign language is to study it in the country where it is spoken in class recently. Some of my classmates believe that to study the language in the country where it is spoken is the best way to learn a foreign language. And some think going abroad is not necessary the best way to learn a foreign language. In my opinion, the best way to learn a foreign language is to study it in an environment of that language. And it does not matter whether we go to the country where it is spoken or not yet.
First of all, a foreign language environment is very important in language learning. If we have a friend who speaks that language we want to learn as his or her mother tongue, it will be effective in language learning through chatting with him or her in that language. Learning a foreign language conversationally can help us improve our listening and comprehensive competences as well as our oral language in the same time.
Second, we can build a foreign language environment even if we are not living in the country where the language is spoken. Making a foreign friend is a good way. Besides, joining a salon of that language and chatting with other foreign language learners in that foreign language and participating in various activities about language learning are all useful in building a foreign language environment. And there are many fairly good language software programs and language learning websites on line, which we can have an access to them easily.
In a word, the best way to learn a foreign language is not definitely to study the language in the country where it is spoken. Instead, it is to build a foreign language environment around us and make great efforts in language learning.解析： 暂无解析 -

【参考范文】
We live in 21st century. It has become a common desire for young and middle-aged people to own their own cars. For a car of his or her own is generally taken as the sign of a modern man.
However, I always wonder why do people spend so much money and time buying, maintaining and parking a private car and risking their lives in the crowded traffic jams during the rush hours when there is a very efficient public transportation system by which people can go anywhere quickly and conveniently? Also, wouldn’t it be better to develop and improve on a better subway, commuter bus and a nation-wide railway and superhighway system in big cities?
Therefore, what I’d like to do now is to see and wait. And, in turn, I suggest the government should restrict the buying and selling of private cars in big cities to protect our environment.解析： 暂无解析 -

Many people are against the opinion that smoking should be banned in public places for it takes away the smokers’ rights, however, in my mind, it protects more people’s rights and we should strongly support it.
Smoking in public places has many bad effects. On the one hand, it harms the health of the people around, for as we know, smoking can cause more damage to the passive smokers than to the smokers. On the other hand, it pollutes the environment by giving off poisonous gas into the air, which may make other people feel uncomfortable.
Banning smoking in public places is very important and necessary to protect our health and environment. The smokers do have their rights to smoke, but they should enjoy their rights on the basis of not harming that of the others.解析： 暂无解析 -

Positive and Negative Effects of Computer With the rapid development of information technology, computers play more and important part in our daily life. Nowadays, it has paid more people attentions than before. Different people have different attitudes.
Most people think that computers have positive effects on us. Firstly, it can enrich our horizon. We can learn more knowledge and get more information about the world. Secondly, it can make our office work efficient. Instead of these paper, pencil, ruler, calculator and so on, now we can deal with the files, cartographies, tables by a computer. Thirdly, it can make our communication easily. It is more convenient to talk to parents or friends when they are far away for each other or cannot meet instantly. Moreover, it is good for our children in the school. Their classes are no longer dull, instead of colorful. Maybe they can learn more useful knowledge by see a movie.
It goes without saying that every coin has two sides, so does computers. Many teenagers become so addicted to computer games or online chat that they ignore their study. Some of them even do not go to school instead of go to the Internet cafes. In order to play a game, they maybe steal money even robbing others. In that case, they will become a criminal. Besides, some smart criminals are use of cyber to crime, they are called “hackers“.
As far as I am concerned, the positive effects of computer are important as the negative effects. Therefore, we should make good use of computers and let them do well to people and make our life wonderful.解析： 暂无解析 -
