二.HAS BEEN 和 HAVE BEEN

现在我们开始作练习. 首先请你听一个英文句子: The campus is noisy today.

"今天校园里很吵", 如果我们不指明校园哪一天很吵, 只说 "校园里一直很吵", 用英文可以这样说: The campus has been noisy.

下面我们多多练习这类句子. 这些句子都是跟学校生活有关系的, 比方宿舍一 直很吵, 食堂一直很挤等等. 每个句子老师念两遍.

M: The campus has been noisy.

F: The campus has been noisy.

M: The dormitory has been noisy.

F: The dormitory has been noisy.

M: The student center has been crowded.

F: The student center has been crowded.

M: The cafeteria has been crowded.

F: The cafeteria has been crowded.

下面一些句子的主词都是多数的, 所以用 have been.

M: The students have been enthusiastic.

F: The students have been enthusiastic.

M: The courses have been difficult.

F: The courses have been difficult.

M: The lectures have been interesting.

F: The lectures have been interesting.

下面我们换一个方式作练习. 由老师提出一个问题, 比方: "鲍勃一直很懒吗?" Has Bob been lazy? 或是 "食堂一直很脏吗?" Has the cafeteria been dirty? 听了 老师的问题之后, 请你用 has not, 也就是 hasn't 作否定的答覆. 每作完一句, 就 请你听老师念正确答案.
