| 词组 | require |
| 释义 | 1．The rule requires (of) all the clerks to arrive at the office by two o'clock 和 The Minister requires (of) you to attend a special conference to be held on Monday 等句子里的 of 用的少，不用的多。用了 of，那 requires 把不定式 to arrive 和 to attend 作宾语，of all the clerks 和 of you 都是状语短语，所以不可说 All the clerks are required of to arrive at the office by two o'clock 和 You are required of to attend a special conference to be held on Monday，该把 of 删去。 上面两句里的 requires 都作 orders 或 commands 解，只用在正式文字里。 2．require 后面的以 that 引导的从句里用 shall 或 should。例如：The rule requires that all the clerks shall（或should）arrive at the office by two o'clock.和 The rule required that all the clerks should arrive at the office by two o'clock.也往往用虚拟现在式。例如：We require that each of you reply（不用 replies）promptly.和 We required that each of you reply（不用 replied）promptly. 3．He required an apology of her 和 This is all that is required of you 等句子里的 of 不可改作 from。 4．require 后面的动名词一定属于主动语态，但在意思上一定是被动的。例如： The dog will require watching. The whole place requires cleaning. The baby requires looking after. The matter requires thinking over. 假使把动名词改作不定式，必须用被动语态。例如： The dog will require to be watched. The whole place requires to be cleaned. The baby requires to be looked after. The matter requires to be thought over. 5．require 的宾语后面有时接过去分词。例如：The storm required all the windows closed. 6．required course（必修科）和 required subject 是美国英语。在英国通常不用 required 而用 compulsory 或 prescribed。 |
