问题描述:

there is some rubbish on the grounp.Please __A pick them up B pick up themCpick it upDpick up it

A
前边是some

选D
rubbish 是不可数名词,只能用代词it 。另外代词it 只能放在动词短语中间,所以选C.
希望可以帮到你。

C something 看做第三人称单数,用it代替 C 地上有东西,请把它捡起来.

A pick it up
pick up 把。。。捡起来
名词可以放在pick up中间或后面
但代词如it these them等要放在中间
这类的表达有好多
put the smoke out 把烟熄掉
turn it off 把它关了
switch on the power 把电源打开
