题目内容
11.对一个13岁的男孩来说,独自去外国旅游真的是很勇敢.It's braveofa 13-year-old boytotravelaround the foreign countries alone.
分析 It's,of,to travel.
解答 答案:It's,of,to travel.本句是说客观事实用一般现在时,根据句意是表达某人做某事是怎样的,这里的brave是形容人的品质,用句型It's+adj+of sb.to do sth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,旅游的动词是travel,故答案是It's,of,to travel.
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.
It's important for us to learn English well.对我们来说学好英语很重要.
