The experiment the students of science devoted themselves to _____ at last.A.succeedB.succeedingC.have succeededD.succeeded讲讲
选D吧,读读,D比较有感觉.
这句话是说,学SCIENCE的STUDENT专注于做的实验终于成功了.

D
主语就是experiment .the students of science devoted themselves to是定语修饰experiment

The experiment the students of science devoted themselves to succeded at last.
The experiment (the students of science devoted themselves to)succeded at last.
()里是定语从句,选项应该填主句动词,由于是过去时,所以succeded

楼上的二位说的对。
