11.我认为年轻人对老年人要有礼貌是非常必要的.I think it's necessary for the young people to be polite to the elderly..分析 I think it's necessary for the young people to be polite to the elderly.
解答 答案:I think it's necessary for the young people to be polite to the elderly.这里是说客观事实用一般现在时,结合句意这里需要用含有宾语从句的主从复合句来表达,主句是I think我认为,后接上省略引导词that的宾语从句,从句年轻人对老年人要有礼貌是非常必要的,用句型It's+adj+for sb.to do sth对某人来说做某事是怎么样的,形容词necessary必要的,年轻人the young people,对…有礼貌be polite to sb,老年人the elderly(the+adj表示一类人),故答案是I think it's necessary for the young people to be polite to the elderly.
点评 It's+adj+of/for sb.to do sth.是一常见句型,其中的it 是形式主语,后面的动词不定式(短语)才是真正的主语.另外,此句型中用of 还是for 取决于其前的形容词,若形容词表示的是人的品质、性格(如:kind,nice,clever,right…),需用of; 若形容词只是对动作的一般性描述(如:difficult,dangerous,important…),则用for.例如:
It's nice of you to say so.你这样说真是太好了.
