Ⅰ.语法单句填空
1．—I haven't got the reference book yet，but I'll have a test on the subject next month.
—Don't worry.You________have it by Friday.
答案：shall 句意：——我没得到参考书，可我下个月要参加这个科目的考试。——别着急，到星期五你一定会得到它。本题考查情态动词的用法。shall可以表示承诺、决心、命令或指示，意思是“必须，一定，应该”。
2．His favorite food is fried snacks and soft drinks. ________ is no surprise that losing weight is just his dream.
答案：It 句意为：他最喜爱的食物是油炸小吃和不含酒精的饮料，毫不奇怪减肥对他来说只是个梦。it在这里作形式主语。“that losing weight is just his dream”是真正的主语。
3．(2012·新课标卷Ⅰ改编)It is by no means clear ________ the president can do to end the strike.
答案：what 句意为：总统能做什么来结束罢工，这点完全不清楚。本句中的it是形式主语，真正的主语是从句what the president can do to end the strike。在从句中，what作do的宾语。
