Question

31. All the task ______ ahead of time, they decided to go on holiday for a week.

A. had been finished             B. were finished     C. having been finished         D. been finished

Answer 1

C

解析:

31. C�？疾楠�(dú)立主格結(jié)構(gòu)。finish與主句的邏輯主語(yǔ)they沒(méi)有關(guān)系，所以要在finish前加上其邏輯主語(yǔ)all the task，而且與之是被動(dòng)關(guān)系，強(qiáng)調(diào)完成，因此可以用having been finished。
