3.There isn't any difference ______ the two.I really don;t know _______.
A.among;which to choose B.among;to which choose
C.between;which to choose D.between;where to choose

Answer 1

B 根据语境,应该是被动语态,（他不需要被告知）排除C和D.而need后面有个to be,因此在句中是做实意动词,应该用doesn't need
A in+名词相当于形容词的用法,比如in danger=dangerous,great是修饰need
C 两个应该用between,三个或以上才用among.这两个没有区别,我不知道要选哪一个.后面一空应选 which to choose.
