So when anyone is on difficulty, we shoul d give him a hand .but under certain circumstances should we say "No‖ when we are asked for help. For example, when we were asked to de something illegal.But it is very hard for some people to say "No" when they ought to . They can't very well refuse, because they are afraid of being regard as being miserly or inconsiderate and even afraid of being isolated from others.Deep down in their hearts, they are reluctant; they don't speak out what's on their mind.Such kind of situation is harmful to both the giver and the receiver. To the giver, he doesn't take the full responsibility for what he done. His help may lead to the receiver's full dependence of others and sometimes even become a factor in helping the receiver go astray. So don't hesitate to say "No" when you ought to.Unit Two1-20 DDCDA CDBCD BAAAB AAABA21-40 DBBBC BDABB CDCAA CDCDBII Cloze41-50 ACEKJ MLOHF51-60 CJGMO FDKBI61-65. ABCDA 66-70.BCABB 71-75. CDABC 76-80.

WritingFast FoodFast food is becoming more popular in China, especially among children and teenagers. Today, it's certainly difficult to think of any other single thing that represents the fast pace of modern society as powerfully as fast food.There are several reasons for its popularity. First, it is very convenient and saves a lot of time. The trends of modern society seem to all point to one ultimate goal —— saving time, and fast food well serves this purpose. You just go into a fast food restaurant, order your food, and your food is ready in no time. You can either eat it there or take it away. Second, its popularity is also attributed to the clean and comfortable environment of fast food restaurants, the excellent service, and the guaranteed quality of food.However, in terms of nutrition, fast food is far from satisfactory. It usually does not compose a balanced diet and is low in nutritional value. Thus, doctors suggest that people, especially children, eat fast food as little as possible. Although cooking at home is time — consuming and the following washing-up tiresome, it offers healthy and delicious meals your body likes and needs. Fast food is only a good choice when you are in a hurry and turn to it once in a while. Unit Three1-5 DAAAD 6-10 CBCCD 11-15 CDABA 16-20 BCCDD21-40. BDBAB ACABC DBCAC ADBAD41-50 HCNLO KGJFA 51-60.

WritingCars and Air PollutionToo many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death. Last winter, car fumes formed heavy smog over Beijing, making the sky gloomy for weeks and deteriorating people's health.One possible solution is to design and develop clean cars and clean fuels. In Tsinghua University, campus buses are driven by electricity. In Beijing some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars to completely replace the traditional ones.Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not private cars. And the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the co-efforts from the government, the public and the environments. This problem will be solved only with the help of science and technology.Unit Four1-5 CDBCD 6-10 BCCCD 11-15DCCAD 16-20 CCACA21-40. BCCCD DCBAC BCCBA CBACBCloze41-50 EHALB MJDGI51-60.
