    【题目】 We can have ________ bluer sky if we create _________less polluted world.

    A. a; a B. a; the C. the; a D. the; the

    【答案】A

    【解析】

    试题分析：句意为：如果我们营造一个没有污染的环境，我们就可以拥有一个蓝色的天空。a/an均可修饰单数可数名词，表示泛指，相当于one；a用于辅音发音开头的词前, an用于元音发音开头的词前。the表示特指说话双方都知道的人或物。根据语境可知，“蓝色的天空”和“没有污染的环境”均表示泛指；blue和less为辅音发音开头的词，故应选A。

It was then that my aunt took me to a sports club one Saturday and I saw so many young people playing different kinds of sports there. I signed up for a beginners’ course in volleyball and since then I have been playing this sport. Now I practice twice a week there. It is wonderful playing sports in this club and I have made lots of friends as well. 【2】”
