toytrain英语儿歌

这个是非谓语短语作后置定语，修饰a large toy train，首先，咱先看看a large toy train 非谓语中做什么，显然，作宾语， to do 用作主动形式表被动意思，是说火车玩具被玩。所以选择A。对于B，如果有了 it ，那么非谓语中啥都不缺了（不考虑逻辑主语阿。）火车玩具咱就不知道放哪了不是？所以不能选。对于加不加it ,主要就是看被修饰词在非谓语中作什么成份，莫要让it 把 修饰词在非谓语中的位置挤掉，这种找位置的方法在定语从句也管用。 eg. the boy's father bought him a large toy train —— A 。which the boy can play with B .which the boy can play with it a large toy train 依然在定于从句中作介词with的宾语，不能让it 挤掉它，所以选A
