定时训练(4)
Ⅰ.专题特训(情态动词与虚拟语气)
一、根据提示或语境填入适当的情态动词，使句意完整，然后熟读感悟。
1．When I lived with my roommates in the university，we ________ often talk into the night.
解析 句意：当我在大学与室友一块住的时候，我们常常谈话到深夜。would 在此表示过去的习惯性动作，其他几项没有此意。
答案 would
2．Students ______ remain in their seats until all the papers have been collected.
解析 句意：学生应该坐在他们的座位上，直到所有的试卷被收上来。该空 shall表示规定、命令，故选B。
答案 shall
3．She didn't come to the party last Sunday.________，she must have made the party more exciting.
解析 句意：上星期五她没有来参加那个宴会。如果来的话，她肯定能使那个宴会更加令人激动。在虚拟条件句中，如果将If省略，则将助动词提前。Had she come＝If she had come。语境为与last Sunday 的事实相反。
答案 Had she come
4．—Why does Thomas speak through every discussion but never listen to the others?
—That's what he ______ do.We used to hate that，but are used to it now.
