问题26: 有一句句子是这样的“It is the first time that I have visited the     Great Wall of China”，可是我记得我们老师经常说“It's time we had class”。 请问我是否也可以用过去时替换这里的现在完成时呢？BBS.EnglishCN.com是英语学习者和爱好者交流与提高的地方7t7C2s6b"C*]"a"H

+|8v:G;t-N(s.@&K t2U回答: 不可以。“It is the first (second, etc.) time+ that clause”是一个固定的结构，从句中谓语动 词一定要用完成时。如果主句为一般过去时，从句中谓语动词则用过去完成时，如： It was the    second time I had been    there. “It is (about/high) time + that clause”是另一个固定用法， 从句中一定要用过去时。

(W/T$o(M(H#U4V英语论坛Answer: Class is one of the collective nouns. Collective nouns are usually singular but may be plural if the members are functioning independently.

回答: Class是一个集合名词。集合名词通常用作单数，但如果强调其中的成员时，也可用复数。主语的单复数可以根据句中用到的的代词来做判断。此类名词有class， team, police, committee, audience, family, faculty等。英语论坛2_#K.g5|3H'^#}

Question 28:    It's hard for me to decide whether a noun for nationality that end with -ses,-ch, or -sh should take a singular verb or a plural one. Can you give me any suggestions?英语论坛8o5S3f-h"g"A8p1E

+N#K6L7L:b:R%z-c英语论坛Answer: Nouns for nationality that end with -ses, -ch, or -sh may be singular or plural depending on their meanings. Some of these words are Chinese, French, English, etc. When the word refers to a language, it takes a singular verb. When the word refers to the people of the country, it takes a plural verb and is preceded by the article "the".英语论坛.F4C*Z)Y.f

回答: 以-ses，-ch，-sh结尾的国家名词的单复数取决于他们所表达的意思。这类名词有：Chinese，French， English 等。当这些词表示该国家的语言时，要用单数。当这些词表示一个民族时，则要用到复数，并且前面一定要加定冠词the。
