   带星号的形容词也可与that从句连用,有时that…should更常见。


  在B-E节中句子用it引导的结构。如果it+be…前的动词是find(发现)/think(想)/be-lieve(相信)等,有时可将that及动词be省略:
  He found that it was impossible to study at home.相当于:
  He found it impossible to study at home.他觉得不可能在家学习。
  1 it+be+形容词(+of+宾语)+动词不定式结构主要与下列各类形容词连用:
  (a)表示性格的有:brave(勇敢的),careless(粗心的),cow-ardly(怯懦的),cruel(残酷的),generous(大方的),good(好的),nice(=kind善良的),mean(吝啬的,卑鄙的),rude(粗鲁的),selfish(自私的),wicked(邪恶的),wrong(不对的)等。与否定动词或疑问动词连用的有:fair*(公正的)/just* (正义的)/right*(对的)。
  (b)表示智能的有:clever(聪明的),foolish(愚蠢的),idiotic*(呆痴的),intelligent(有才智的),sensible(有见识的),silly(傻的),stupid(愚蠢的)。
  此外, absurd*(荒谬的),ludicrous*(荒唐的),ridiculous* (滑稽的)和unreasonable*(不合理的)有时也可这样使用。
  It was kind of you to help him.
  你帮助了他,真好心。
  It was stupid(of them) to leave their bicycles outside.(他们)真傻,居然把自行车放在外面了。
  (b)组形容词后的of+宾语结构可省略。有时该结构在(a)组形容词后也可省去,但good和nice除外。(后二者如果省略of+宾语则会改变good和nice的意义。参见E。)2代词+be+形容词+名词+动词不定式既可以与上面的形容词连用,又可以与下列形容词连用:astonishing*(令人惊讶的),curious*(奇怪的),extraordinary*(不寻常的),funny* (=strange*稀奇的),odd*(怪的),queer*(怪的),surpris-ing*(令人惊讶的)等。此外还有pointless(无意义的),useful(有用的)和useless(无用的)也可以这样使用。
  It was a sensible precaution to take.
  这样预防一下是明智的。
  That was a wicked thing to say.
  说那种话太恶劣了。
  这种评价式的话有时可用惊叹句来表达:
  What a funny way to park a car!
  这样停车好怪!
  What an odd time to choose!
  选的时间多怪!
  有时在一些表示不赞成的句子中,形容词可以省略:
  What a(silly) way to bring up a child!
  怎么用这种(愚蠢的)方法带孩子!
  What a time to choose!
  怎么选了这么个时间!
  that从句的例句如:
  It is strange/odd/surprising that he hasn’t answered.真是奇怪/古怪/令人惊讶,他怎么没回音。
  it+be+形容词+动词不定式结构中可以用下列词:advisable*(合意的),inadvisable*(不可取的),better*(较好的),best(最好的),desirable*(可取的),essential*(必要的),good(好的,可取的),important*(重要的),necessary*(必要的),un-necessary*(不必要的),vital*(非常重要的)。也可以用only+fair*(公平的)/just*(合理的)/right*(对的)。
  例句如:
  —Wouldn’t it be better to wait?
  —No,It’s essential to book in advance.—等一等不更好吗?
  —不行,必须预先订票。
  可在除good以外的形容词后或在just后加for+宾语,但在good后会改变其意思,见下文E:
  It won’t be necessary for him to report to the police.他没必要去报告警察。
  It is only fair for him to have a chance.给他一次机会才是公平合理的。
  inessential(非必要的)和unimportant(不重要的)通常不这么用,但可以说not essential。
  it+be+形容词(+for+宾语)+动词不定式结构中可以用下列形容词:convenient*(便利的),dangerous(危险的),diffi-cult(困难的),easy(容易的),hard*(艰难的),possible*(可能的),impossible(做不到的),safe(安全的),unsafe(不安全的)。

  It’s interesting(for children) to see a house being built.(孩子们)看造房子是挺有趣的事。
  It was marvellous(for the boys) to have a garden to play in.(男孩子们)能有个花园在里面玩耍,真是妙极了。
  注意:如在good后面加上for+宾语,则把good的意义限制在healthy(有益健康的)/beneficial(有益处的)方面:
  It’s good for you to take regular exercise.经常锻炼对你的身体是有好处的。
  (good+动词不定式既有这种含义,也有“愉快的”/“好心的”和“适当的”等意思,请参见上面的B节与C节。)it+be+形容词+名词+动词不定式结构也可和上述形容词及分词连用:
  It was an exciting ceremony to watch.
  观看这个仪式真叫人兴奋。
  It was a horrible place to live(in).

  I’m delighted to see you.
  我见到你很高兴。
  这里最常用的动词不定式有:to find(发现)/learn(得知)/hear(听说)/see(看到),但glad(高兴)/happy(幸福)/sad(悲伤)/sorry(抱歉)等形容词后面也常常使用to say(说)/tell(告诉)/inform(通知)及其他一些动词不定式:
