问题
选择题
As Jack left his membership card at home, he wasn't allowed into the sports club.
A．going
B．to go
C．go
D．gone
答案
B
题目分析：本题考查单词allow 的用法，allow sb. to do sth.和allow doing sth.，但是变成被动语态是sb. is allowed to do sth.， 句意：因为杰克把会员卡忘在家里了，他不被允许进入体育俱乐部，所以选择B。
点评：要记住allow的基本搭配结构和含义，往往allow会用被动式，be allowed to do，学生可能因为allow 后面没有宾语而直接选择了A。
