8．construction　根据空格前的形容词"great"可以判断，空格处被形容词修饰，故用名词形式。

　　9．visitors　这里指"保证国内外游客的安全"，故用名词的复数形式。

　　10．hanging　句意：从远处看，这座桥就像是悬挂在江上方的彩虹。空格处与rainbow之间存在逻辑上的主动关系，故用现在分词。

　　Ⅱ.短文改错

　　Dear Lisa，

　　I'm glad to receive your letter asked about the present holiday life of Chinese students. Learning together with entertainment still take up most of our time. Besides, we often help our parents with the housework or farm work, that makes us realize how hard we work every day and develop a great love for work. Meanwhile, we take active part in social activities, such as voluntary work. We went out to the streets to collect rubbishes or to the hospitals to cheer up the sick children. We try our best to help those who are in need or make our hometown a lot of more beautiful. We find greatly pleasure in these activities.

　　Yours，

　　Li Ming
