题目内容


_____ is no doubt _____ John’s knowledge of first aid saved Ms Slade’s life.
A．It; thatB．It; whichC．There; thatD．What; that
C

试题分析：固定句型there is no doubt that…毫无疑问的是… 句意为：毫无疑问的是，约翰的急救方面知识救了斯莱德女士一命。doubt在这里作名词“疑问、怀疑”；that引导同位语从句，解释说明怀疑的内容。A 不行只有it is no wonder that 难怪
点评：本题重在平时学习过程中多积累重点句型，考试时一眼就能看出，更不用去分析句子的成分。如果是doubt 作动词用在陈述句中，其后多跟whether/if，构成I doubt whether/if…“我怀疑是否……”.此外，平时要多注意there is 构成的短语的积累，如：there is no point doing sth 做某事毫无意义
