1. A.
   throw it
2. B.
   throw away
3. C.
   throw away it
4. D.
   throw it away

Answer 1

D
分析：人称代词作动词短语的宾语时，要注意动词短语的性质，如果是“动词+副词”类型的话，必须插在这短语中。throw away就是这样的短语，所以要说throw it away，不能说throw away it．如果是名词作宾语throw the trash away/throw away the trash都可以。(延伸)另一种动词短语是“动词+介词”类型，无论宾语是名词或代词都必须放在后面，如：look at me/look at the blackboard．
