20、y.49It is dangerous _ children to play with fire.50It is silly _ her not to forgive others for their mistakes.参考答案:1A【详解】句意:对我们来说,当我们遇到难题的时候,和我们的父母谈谈是很有必要的。考查It的固定句型。Its+adj.+for sb.+to do sth.意为“对某人来说,做某事是怎样的”,句中it是形式主语,真正的主语是其后的动词不定式,本题空处应填不定式,故选A。2D【详解】句意:你在这里等了两个小时,你很有耐心。根据句型It is +描述事物的形容词+for
21、sb to do sth对某人来说,做某事是,根据It is+描述人物性格的形容词+of sb to do sth.表示某人做某事,某人是,此处patient“有耐心的”,是描述人的形容词,故第一空用介词of,it是形式主语,动词不定式做真正主语,故第二空用to wait,故选D。3A【详解】句意:对我们来说,保护野生动物是重要的。It is +描述事物的形容词+for sb to do sth对某人来说,做某事是,根据It is+描述人物性格的形容词+of sb to do sth.表示某人做某事,某人是,根据to protect the wildlife可知此处指的是保护野生动物,这件事是
22、重要的,故用介词for。故选A。4C【详解】句意:那些妇女穿着动物毛皮制成的衣服,她们是不对的。be made of由制成的,make up编造。根据It is+描述人物性格的形容词+of sb to do sth.表示某人做某事,某人是,it是形式主语,to do sth是真正主语。故选C。5A【详解】句意:不要担心。很容易解决这个问题。根据句型Its+形容词+to do sth.“做某事是”,it是形式主语,to do sth是真正主语。easy容易的,是形容词;easily容易地,是副词,故排除BD两项。enough修饰形容词,位于形容词的后面,故选A。6D【详解】句意:汤姆没有改变主意
23、,他真是太顽固了。It is+描述人物性格的形容词+of sb to do sth.表示某人做某事,某人是;It is +描述事物的形容词+for sb to do sth对某人来说,做某事是;it是形式主语,to do sth是真正主语。此处stubborn是描述人的形容词,故用介词of。故选D。【点睛】1.在It is +形容词 + of + sb.+ to do sth.中, 形容词是说明sb的。重点说明“sb is 形容词”某人是怎样。形容词是描述不定式行为者的性格、品质的,如kind,good,nice,right,wrong,clever,careless,polite,fooli
24、sh等。2. 在It is +形容词 + for + sb.+ to do sth.中, 形容词是用来说明to do sth的。重点说明“to do sth is 形容词”做某事是怎样。形容词仅仅是描述事物,不是对不定式行为者的品格进行评价,这类形容词有difficult,easy,hard,important,dangerous,(im)possible等。7D【详解】句意:他在旅途中照顾这么多孩子不容易。easy是不可以修饰人的形容词, 即sb.和adj.没有主系表关系,因此,第一个空sb. 前用for。排除A/C。so副词,意思是“如此、这样”,后面常接形容词或副词;such形容词,意思
25、是“如此、这样”,修饰名词,即可接可数名词,也可以接不可数名词。many是形容词,因此用so来修饰。如此多的孩子,用so many children。故选D。【点睛】Its + adj. + (of / for) sb to do sth. 译作“(某人)做某事是的”。It 是形式主语,不定式结构是真正主语。of / for后面的sb是不定式的逻辑主语。1. 当形容词是可修饰人的形容词,即sb和adj. 有主系表关系时,sb. 前用of。如 Its clever of you to answer the question so quickly. / Its kind of you to hel
26、p me a lot. 这样的形容词有:kind, nice, rude, clever, silly, foolish等。2. 当形容词是不可以修饰人的形容词,即sb和adj. 没有主系表关系时,sb. 前用for。如 Its easy for her to clean the window by herself. / Its important for us to learn English well. 这样的形容词有:easy, hard, difficult, important, necessary, dangerous等。8B【详解】句意:你不接受你父母的建议是不对的。考查动词不定
