Question

1.There I met several people, two of them _________ foreigners. A.being B.were C.are D.had been

2.By the time they get here,we_____the work
A.have finished B.had finished C.will have finished D.will finished
请详细说明~

Answer 1

1，A.being
two前面是逗号，而two前面没有连词，说明后面的不是一个句子，而是一个独立主格结构，用being；如果two前面是句号，则说明后面的部分是个句子，用were，同时two的首字母要大写T.下面的三个句子均为正确表达，意思相同：
（1）There I met several people。Two of them were foreigners
(2) There I met several people,two of whom were foreigners.
(3) There I met several people，two of them being foreigners
2，C.will have finished
by+将来一个时间点，是句子用将来完成时的标志

Answer 2

1.B
并列句，前后时态保持一致

2.C
by结构，常与完成时一起使用；时间状语从句遵循主句用将来时，从句用现在时的结构。

追问

第一题为什么是并列句？又没有and

追答

应该有的，没有的应该是印刷漏了，没有and不能用two of them。

Sorry,我分析错误，若没有and，只能是如“第46个浪人”所说的独立主格结构了。

追问

明明是“第47个浪人”。。

追答

囧rz，是了，是他就是他。

Answer 3

B，就近原则
A，完成时，看到By the time 就用完成时

Answer 4

1.A
2.C
