动词后面加介词?补是说.不及物动词后面加介词,但后面要有宾语的么?这几个是怎么回事么?penguins are take

（别着急,希望我的解答令你的困惑烟消云散：）一,关于“penguins are taken good care of in New Zealand。Young trees should be （a。taken good care。【a。taken good care b。take good of c。looking after well d。well looked after】）为什么一个加一个不加of呢?”两个句子的of都不能少。即第二个句子的正确选项是d。well looked after,而不是你说的a。taken good care。凡是（不及物）动词后面加了介词,所组成的动词短语,改为被动语态时,这些介词都要一一保留,不能删去。这是许多学生容易出的差错。二,关于“however,his parents won't allow him to trains as much as he would like to。为啥加to呢?”这是简略句。像这类like to/would like to/would love to 等简略句,带有不定式,当要承前省略时,要保留不定式的标志to。楼主请看下面的对话：---Tom,I am going to the theater this afternoon。Would you like to go with me?---I‘d love【 to】。But I am have to stay at home to do my homework。三。关于“old people should be spoken to。为什么有to?”这个问题同“第一题”,不再累述。四,关于“the teacher was reading when he came in为什么加in”这里的in是副词,而非前面所说的介词,与前面所说的是两回事。come in 和come out 一样,可以单独使用而不用带宾语。这里省去in也通,只是意思不一样。come in 是“进来”的意思,如果没有in,就是“来”的意思。有in没in意思不同,看你要表示何种意思。五,关于“ agree ( )what he said 这里使用in,on,还是with?” with 是对的。agree with what he said 是“同意他说的话”的意思。（如再有疑问,敬请垂询,）
