Question

---He_____ attend at the meeting.
--- But in fact he didn’t come.
A. is suppose to        B. was suppose to  C. was supposed to

Answer 1

C

試題分析：句意：他應該出席這個會議。——但是實際上他沒有來。可知上文描述的是過去發(fā)生的動作，故用過去時態(tài)，他是被期望的對象，用完成時態(tài)，選C。
點評：被動語態(tài)be supposed to已經(jīng)成為一個固定結(jié)構(gòu),本句只要能根據(jù)上下文判斷出上文時態(tài)即可.
