The workers____ _____(make)____ _____(work)twelve hours a day last year .(用动词的适当形式填空)

四个空分别填were made, to work.

The works planted trees last month.改成现在完成进行时。

The worker are planting the tree

The workers were made__________(wprk) for 12 hours a day in the past.

hear doing sth.

应该是crying

made to do sth. 让做 ...

这里填to work

the worker have built a lot of

选择since a few years

have built 现在完成时

in the past ten years 应该用过去时，则应该用had built（过去完成时）

for ten years 单纯的标明时间，只表明动作完成，就可以直接用过去式：built

a few years ago 多年前，过去式，同上
