How to choose,translate and why? Thanks.
您好！be determined to do sth. 和 determine to do sth. 都是对的。B ,D 如何选择？

Answer 1

B
be determined to do sth.决定去做某事。
determine to do sth是非延续性动词不能与表示一段时间的状语连用,
be determined to do sth是一种延续状态,可以与表示一段时间的状语连用

Answer 2

D，自从他来到Central China Normal University，刘教授就已经决定要教心理学。
determine to do sth.表示主动的，此处是刘教授决定，用主动态。
be determined to do sth.是被动语态，什么事情被决定，
如：It is determined to finish this program in this month.

Answer 3

看来你可以排除AC

determine是及物动词，determine oneself to do，BD后面都没跟宾语，所以处理成被动，be determined to do，由于是现在完成时，been determined to do

自从刘教授来到Central China Normal University，他就下定决心教授哲学

Answer 4

B 下定决心做某事,表示心理下决心之意。比determine to do 表示行动的要好
