注 1:一般疑问句通常要求用 yes 或 no (或 not at all 等)来回答。对问句表示同意时,除 yes 外,还可用下列同义词语:certainly一定,of course 当然,please do 请便好了,with pleasure 好的,if you please 随你便,quite so 相当对,exactly 正是如此,absolutely 绝对是的,quite right 说得对(或很对),I think so 我想是这样的,yes, if you like 是啊,随意好了,by all means 完全可以或务必这样等。
注 2:英语用否定句形式提问,而在回答时,仍可把它视为肯定句形式的问句来回答。但译成汉语时,差别很大。例如:
Haven't you been to Shanghai? 你没去过上海吗?
Yes,I have. 不,我去过。
No,I haven't. 是,我没去过。

注 1:如果特殊疑问句中插入以一般疑问句形式出现的插入句,则特殊疑问句本身的主语、谓语仍按正装语序排列。例如:How many test-tube babies did she say she had seen there? 她说她在那边见到了多少个试管婴儿?
注 2:注意句子成份不齐全的特殊疑问句。
1) What about our going shopping? 我们去购物怎样?

6) I wrote a letter yesterday. 我昨天写了一封信。
Who to (或 To whom)? 给谁写的?
注 3:名词从句(如主语从句、宾语从句、表语从句等)用疑问词引导时,其后面的主语、谓语不必颠倒。例如:I don't know when the conference will be held. 我不知道该会何时举行。(when 引出宾语从句。若将 I don't know 改为 My question is, 则 when 引出表语从句。)

2) a. Send an e-mail, will you? 发一封电子邮件,好吗?(用于第二人称,含有命令口吻。不算反意疑问句。)
b. Have a cup of tea, won't you? 请喝一杯茶。(用于请客场合,仍是反意疑问句。)
c. (It is a) Fine day, isn’t it? 天气很好,是吧?(仍是反意疑问句。)
- When was it that he made up his mind to take a trip to Beijing? 是什么时候他决定去北京旅行的?(被强调的是状语 when。因它是疑问词,在构成特殊疑问句时就置于句首,后面 it was 也就颠倒。)

同时也须注意,用 so 代替前句(限于肯定句)中出现的句子成分,并要求句子成分倒装(见第 10、11 句)。在否定句中,则用 neither 或 nor 代替否定句中出现的有关成分(见第 12,13 句)。

从上述例句中可看出,从句只作句子某个成分,并且还要靠 that(无词义;仅在第 6 句中 that 代替前面的 machine,并在从句中作主语),which,where,when,if,since 等词来引出从句。我们把这些词统称为关联词。这些词不限于引导某一种从句,同时还有其它用法。这些正是本手册的重点内容。可在目录中按字母顺序查这些词的用法,又可从语法目录中各种主从复合句中查出这些词可引导哪几种从句。这里,我们拟提一下 where by(借此,凭此),whence(自该处),where in (在那里,在那点上),where on(在那上面)等引出定语从句的用法,并举例如下:
- This is the best method where by (=by which) we produce such chemicals. 这是我们生产这样一些化学制品的最好方法。
- He has returned whence (=to the place from which) he came. 他已回到他出来的地方。
