问题补充：

While shopping, people sometimes can’t help into buying something they don’t really need.

A. to persuade

B. persuading

C. being persuaded

D. be persuaded

答案：

A. to persuade

B. persuading

(答案→)C. being persuaded

D. be persuaded

解析：本题考查非谓语动词。persuade是及物动词，后面要加人做宾语。没有人做宾语时，要用被动形式；由此可排除A、B项；再结合句意“当人们去买东西时，有时候禁不住别人的劝说买了不是真正需要的东西。”可知句中的 can’thelp意为“禁不住”,此时后接doing形式，故选C项。
