It is dangerous for little children to swim in the river.为什么这里用to swim
固定句型
It's + 形容词 + for sb.+ to do sth.
真正的主语是动词不定式 to do sth.
To swim in the river is dangerous for little children.有点头重脚轻,所以用形式主语it
it is 形容词 for sb to do sth 对某人来说做某事怎么样 英文中常用的一个结构
it作形式主语, to swim 是真正的主语
it is +形容词+to do sth
祝你进步
这个可以这么理It is +形容词+for sb to do sth 。It is +adj.+for sb.+to do sth表示做某事对某人来说很adj.
例如:It’s difficult for us to finish the work. 对我们来说,完成这项工作很困难。
动词不定式作主语,IT 是形式主语,这句话也可以这样说:To swim in the river is dangerous for little children .( 英语中使用IT 作形式主语很常见,即 It 's +adj +for sb + to do sth ,是为了避免句子‘头重脚轻’)
句型:It is + 形容词 (for sb.)to do sth. 表示“做某事很。。。”
to 就是表目的“去。。。”
eg. It is happy for you to find a good job.
这是很基本的句型结构,记住就ok,不必管为什么,把英语当数学会越学越南的
因为前面有to所以只能后跟动词原形
有句型IT IS ADJ. FOR SB. TO DO STH.
