20． It’s time we ______ the lecture because everybody has arrived.（0 分）

答
1.D 这个动作是发生在was giving之前的，表示过去的过去，所以要用过去完成时
2.B It's time that 后面的句子要用虚拟语气，这里都要用一般过去时
答
D D
答
5.D 这道题中有两个动作,一个是was giving中的“给”,一个是had given中的“给”,根据题意可知,第二个“给”发生在第一个“给”之前,第一个“给”已经用了过去式,那么过去的过去肯定要用过去完成时.
20.B 这是一道虚拟语气的题目.在It's time这样的句型后面我们常用一般过去时表示现在情况.如：It's time you went to bed.现在该是你睡觉的时候了.
25.B looking forward to是一个词组表示盼望,to是介词,后面要加名词代词或动名词.
