问题补充:
While shopping, people sometimes can help into buying something they don really need.
A. persuade
B. to persuade
C. being persuaded
D. be persuaded
答案:
A. persuade
B. to persuade
(答案→)C. being persuaded
D. be persuaded
解析:考察固定搭配。固定搭配can’t help to do sth不能帮助做某事;can’t help doing sth情不自禁做某事;句意:当人们在购物的时候,人们情不自禁地被说服购买一些他们不是真正需要的东西。根据句意说明使用的是can’t help doing sth“情不自禁做某事”这个结构的被动语态。故C正确。
