Question

The homework is expected to finish before 6 o'clock. 这句话对吗,是to finish or to be finished?

be expected to do sth, 本身就是被动形式.
那么后面到底接主动的还是被动的呢
The homework is expected to finish before 6 o'clock.
The homework is expected to be finished before 6 o'clock.
哪个才是正确的呢

Answer 1

应该用被动语态，作业是被完成的，所以第二句正确。
人作主语时才用主动语态：
You are expected to finish the homework before 6 o'clock.

希望对你有帮助

Answer 2

adj.（用作定语）预期要发生的，期待中的
v.期望( expect的过去式和过去分词 )；预料；要求；认为（某事）会发生

第二句正确

Answer 3

正确表达：The homework is expected to be finished before 6 o'clock.

expect和finish都必须都用被动语态。
