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。
