Nobody knows exactly how many languages there are in the world,partly because of the difficulty of distinguishing between a languageand the sub-languages or dialects within it, but those who have tried to count typically have found about five thousand.
A.and the sub-languages or dialects within it, but those who havetried to count typically have found
C.and the sub-languages or dialects within it, but those who havetried counting it typically find
答案是A, 我知道C 中的it 用的不对,count languages 当然不能用单数it, 但是我的疑问在于 一:try to do 和 try doing 在这里为什么用 try to do 比较好。
二: A 选项中 count 后面总感觉没宾语啊,总要count sth 吧。
谁能帮我解答下呢?谢谢~ |
