Question

By next sunday she _____(stay) with us for three weeks.(适当时态填空）。请告诉我填什么，并且说明原

谢谢
貌似全错，会的才来，

Answer 1

1. 答案：will have stayed.

2. 解释：
1）“by + 某个时刻”意思是“到...为止”，表明句子应该含有完成时态；
2）而next Sunday又表明句子应该含有将来时；
3）所以以上两个时态相结合的话，则该句必须使用将来完成时，即will have stayed.

Answer 2

will have stayed
因为next sunday要用将来时
by 后面加一段时间 表示到了。。。截止到。。时候 用完成时
那么两个叠加 将来完成时
望采纳

Answer 3

will have stayed.'BY NEXT SUNDAY'是将来完成时的标志

Answer 4

will have stayed

Answer 5

would have stayed
这个是未来完成时

Answer 6

will have been staying
将来完成进行时。

next sunday, 将来
for 3 weeks, 完成
be staying, 正和我们在一起。
