    Writing Task II  (20 points)　　Directions: Write a composition of no less than about 160 words, saying whether you agree or disagree with the following statement and giving examples: The biggest dangers to our health and environment come from cars. Remember to write your composition on the Answer Sheet.

    正确答案：
    There is an argument that the biggest dangers to our health and environment come from cars. Some people may agree with this, while others may disagree. In my opinion, I don’t think the situation is true.
    Firs of all, car brings much convenience to our life. Nowadays, with the fast development of China’s economy and China’s entry into the WTO, each year, there is an increasing number of cars on the roads as millions of new cars are produced. Many Chinese people who live in big cities, to a large extent, rely on cars to go to work every day. Without cars those people will have a lot of trouble going to work.
    Secondly, although cars have many drawbacks, there are always many solutions to those problems. One way to get rid of the polluted air is to produce green cars without pollution. Another way is to replace car engines with something else. Inventors are now working on steam cars as well as electric cars.
    Thirdly, cars do post some dangers on our health and the environment, but they are not the biggest cause. Dangers come from many aspects, such as factories or hospitals producing many toxin gas or dumping poisonous water into river.
    In sum, on the one hand, we should take measure to resolve the problems; on the other hand, we could also use the scientific and technical productions.

    A

    B

    it was the possibility of losing her business that gave Helena more concern

    C

    Helena was more concerned towards her business and the possibility of losing it

    D

    the possibility of losing her business gave Helena more concern

    E

    Helena was more concerned about the possibility of losing her business


    正确答案： D
    解析：
    句子以修饰性短语“worried”分词开始，分词的主语必须是主句的主语，但是该主句的主语是“Helena’s concern”，所以A项不合适。分词的逻辑主语只能是Helena，C.和E.符合，选项C不正确，“concerned towards”这个短语不符合语言习惯。故选E。
