题目

think about 、think over
The dress is so expensive,I'll _____ it .
A think B think about C think of D think over
think about :考虑
think over:仔细考虑,重新考虑
到底用B、D哪个?

答案

选B.因为about是介词,接代词宾语时要说 think about it
over是副词,接代词宾语时要说 think it over
动介词组的特点是：宾语一律放在词组后面.
动副词组的特点是：宾语是名词时,宾语放词组中间或词组后均可.如 put on your coat = put your coat on 当宾语是代词时,宾语只能放词组中间.如 put it on
