答: 虽然这些词意义相近,但还是有细微的差别,所以不可以随意替换。如果你*l(\8|9M'l(s6Z
是用make from来描述“制造”这个动作的，在制成品中通常看不出原料，如：English learners' Forum7^(f$g3e*X7C%r V3b9X%q

制成品通常是由很多材料混合而成。有时，其用法也可等同于compose或consist，表示“由……组成”。例如：The City of Shanghai is made up of ten districts.

Answer:    If there's no article before the word "scientist",    "professor" and "scientist"    should be regarded as two identifications of the same person, thus the subject of     this sentence is a singular and we can only use "is" as its    predicate.

Answer: No, we can only use present perfect tense in the sentence    you mentioned.    "It is    the first (second, etc.) time+ that    clause" is a fixed structure and we can only use     perfect tense in its subordinate clause. If the main clause appears    in past tense, the subordinate clause must be in past    perfect tense form. E.g. It was the second    time I had been    there.     "It is (about/high) time + that clause" is another    fixed form and we can only use past tense in the    subordinate clause.

English learners' Forum1B0X8r4S/M*~%_
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。

Question 27: I found that the word "class" is sometimes followed by a singular verb and sometimes a plural one. Are there any rules I should follow?

Watch the pronouns for clues to the singular or plural nature of the subject, some of these words are class， team, police, committee, audience, family, faculty, etc.

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。英语网上资源论坛,中西杂谈,英语问题区,电脑英语论坛,实用英语论坛,翻译论坛-口译笔译,出国考试 ,国内考试,国际交友,同城交流,英语娱乐区,中文休闲屋,论坛精华区,英语学习,英语快餐,English study,English BBS,Forum,英语博客基地"Y7[5E8k(O

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".英语网上资源论坛,中西杂谈,英语问题区,电脑英语论坛,实用英语论坛,翻译论坛-口译笔译,出国考试 ,国内考试,国际交友,同城交流,英语娱乐区,中文休闲屋,论坛精华区,英语学习,英语快餐,English study,English BBS,Forum,英语博客基地-a7A0t"g3l:K)g9K

Answer: When the noun that is being described is actively "doing" the action, the present participle is used as the verbal adjective. But when the noun is the receiver of the action and is passively having something done to it, the past participle is used.

回答: 如果被修饰的名词是主动地做那个动作的，我们要用现在分词形式。但是如果被修饰的名词是动作的接受者，被动地接受这个动作，则要用过去分词的形式。
