问题 Everyone involved in this matter should make a _________ not to leak the secret.
选项 A、pledge
B、warranty
C、assurance
D、guarantee
答案A
解析 惯用搭配题。make a pledge to do sth．为惯用表达，意为“保证做某事”。[A]pledge“保证，誓言”。[B]warranty“担保，保证”，常指法律上的对商品质量和售后服务的担保；[C]assurance“保证”，常用 give/seek/receive/assurance；[D]guarantee“保证，保证书”，不用于本题干句中的结构。
