His mother asks him to do morning exercises, but he is not used to ______ early in the morning.
A.get up
B.getting up
C.be gotten up
D.being gotten up
参考答案
正确答案:B
解析:本题考查的是be used to的用法。be used to之后一般接动名词或名词,意思是“习惯于做某事”,故选项B为正确答案。解答此题的关键是要分清be used to(doing) sth. 和 be used to do sth.的区别,前者意为“习惯于做某事”,后者意为“……被用来做……”。A项和C项在此显然与句意不符。D项“being gotten up”为动名词的被动形式,主语he与get up之间应构成主动关系,故排除。
