All the doctor are trying ______ a new kind of medicine to cure the patient.

问题描述:

All the doctor are trying ______ a new kind of medicine to cure the patient.
A.using B.to use C.to using D.used
try to do是设法、尽力做某事,try doing是试着做某事,我觉得两个都通啊……答案是A,请问为什么呢?

这道题是根据题意得的答案,因为用的是new kind of medicine.医生并不是很了解药的效果,只能是尝试着去用这种药救治病人.总的来说大考里面不太会出现这种模棱两可的题
