二.HAS BEEN 和 HAVE BEEN

現(xiàn)在我們開始作練習(xí). 首先請你聽一個(gè)英文句子: The campus is noisy today.

"今天校園里很吵", 如果我們不指明校園哪一天很吵, 只說 "校園里一直很吵", 用英文可以這樣說: The campus has been noisy.

下面我們多多練習(xí)這類句子. 這些句子都是跟學(xué)校生活有關(guān)系的, 比方宿舍一 直很吵, 食堂一直很擠等等. 每個(gè)句子老師念兩遍.

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.

下面一些句子的主詞都是多數(shù)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.

M: The professors have been busy.

F: The professors have been busy.

下面我們換一個(gè)方式作練習(xí). 由老師提出一個(gè)問題, 比方: "鮑勃一直很懶嗎?" Has Bob been lazy? 或是 "食堂一直很臟嗎?" Has the cafeteria been dirty? 聽了 老師的問題之后, 請你用 has not, 也就是 hasn't 作否定的答覆. 每作完一句, 就 請你聽老師念正確答案.

M: Has Bob been lazy?

F: No, Bob hasn't been lazy.

M: Has the cafeteria been dirty?

F: No, the cafeteria hasn't been dirty.

M: Has the dormitory been quiet?

F: No, the dormitory hasn't been quiet.

M: Has the library been crowded?

F: No, the library hasn't been crowded.

請你用 have not, 也就是 haven't 回答下面幾個(gè)問題.

F: No, the students haven't been late.
