Ⅰ.语法填空
1．How could you walk into the lab with your shoes? You're ________(suppose) to take them off before you enter it. I told you so!
答案：supposed 考查动词词义及习惯用法。由语境可知，此处指“在进入实验室前应该脱鞋”，因此用be supposed to。

答案：turn 考查名词。根据句意“你只好等到下一轮了”可知此处指“错过了轮次”，故用turn。

答案：in turn 句意为：清洁的环境有利于这个城市申办下一届全运会，而全运会反过来又促进了这个城市的发展。
