高三英语~~

1. Why ________ a bicycle al the way around Australia?
A. riding
B. to ride
C. ride
D. having ridden

个人认为选C ，全句应为 Why did you ride a bicycle all the way around Australia?
2. --Who would you like to undertake the project?
--A man ______ Welson.
A. called himself
B. calling him
C. is called
D. you call

个人认为选D 若是B的话应该是calling himself，D为定语从句，A man (who) you call Welson

3. It is said that the small office ______ as the President's intelligence center in wartime.
A. functioned
B. performed(为什么不选这个？)
C. conducted
D. applied

刚才查了一下perform as 有起...的作用的意思，所以应该选B，不知道为什么不选。倒有这样一个短语perform a function as
