Ⅰ.语法单句填空
1．He was worried, because he lost his bag ________(contain) his passport，ID card and a lot of money.
答案：containing 句意：他很担心，因为他丢了装有护照、身份证和一大笔钱的包。contain表示“装有”，与bag构成逻辑上的主谓关系，因此应该用containing。
2．His explanation that he is at ________ loss what to do next doesn't hold water.
答案：a 考查冠词。句意：他对接下来该做什么感到困惑的解释说不通。at a loss意为“困惑，不知所措”，为固定短语。
3．It was mainly for the environmental protection ________ the government decided to have a new city built 600 miles northwest of the original one.
答案：that 考查强调句式。分析句子结构可知，此处为强调句“It is/was＋被强调部分＋that/who”结构，本题强调的是mainly for the environmental protection，因此用that。
4．________ he could call the police, the thieves had run away with the suitcase，leaving him shocked and helpless.
答案：Before 考查连词。句意：他还没来得及打电话报警，小偷已经带着手提箱逃跑了，这使他感到震惊与无助。根据句意可知，A项before“在……发生以前”正确。
5．I'd appreciate ________ if you could come and help me once more and I always appreciate ________(help) me with my English in the past.
答案：it；helping 考查appreciate的用法。I'd appreciate it if...为固定结构，意为“假如……，我将不胜感激”；appreciate后可以跟动名词作宾语。
