Question

用适当的语态或时态填空
1.His work ____ ____(stop)for a time by the First World War.
2.professor James will give us a lecture on the Western culture,but when and where____ ____ ____ （decide)yet.
3.A hundred soldiers ____ ____(send)to Europe to help people there.
4.A mother as well as tow children ____ ____(need) to play this game.

Answer 1

1.has stopped 一般看到“by+时间”都用完成时,表示“到...为止”
2.isn't decided 补充完整为“when and where he will give us the lecture”这里是when 和 where其实是引导主语从句,另外,当and连接的并列主语指的是同一概念,谓语就用单数形式,本题中,when and where he will give us the lecture 是一个概念,所以用单数.
3.were sent 被动语态,一般过去时.
4.is needed 注意as well as是状语,所以不是主语,主语是A mother,单数!
