Question

..
1.When I was only four years,Mom told me that the sun___ (rise)in the east.
2.The children___(play) games when it began to rain.
3.By last Sunday I ___(visit)the zoo four times.
4.—我的电视正在修：My TV set ___________now.

Answer 1

1.rises太阳从东方升起是自然界的真理,要用一般现在时,不管句子的谓语是什么时态；
2.Were playing 根据后面when引导的时间状语从句,该句应用过去进行时；
3.had visited ,last sunday是过去的时间,four times是完成时的标志,所以该用过去完成时
4.is being mended 现在进行时的被动语态.
