不要随便给我个答案 我做完了 .我对下

21A 因为后面有for many years
22C
23C aim at 是固定搭配
24B 因为rencent语法搭配不合理,future的话就和前面的重复了,now肯定是错的,所以就是present
25D 组成的意思Persist in 是坚持的意思
26B
27C
28A 因为此处需要一个副词或者词组,in advance的适用范围比较广一点
29D 因为前面有At one end of the scale ,所以这里end是和前面的对应
30A
31B
32C 因为前面一直在说topic的问题
33C
34C
35A 面试官
36D 因为后面说,只有很强的面试官才能.所以转折
37C
38B 因为要形容词
39D end up 是个短语,结束的意思
