题型：不详难度：来源：

I have little doubt the plan will succeed.

A．that

B．if

C．whether

D．because

答案

解析

试题分析：考查同位语从句。本题中的that the plan will succeed是一个同位语从句，对名词little doubt进行解释说明。句意：我毫不怀疑这个计划会取得成功。因为句子的Little doubt表示的是毫不怀疑，表示的是肯定的意识所以使用that引导；如果表示的是疑问的意思，那么就使用whether。
点评：同位语从句是对前面的名称进行解释说明的，如果表示陈述的意思就使用that引导；如果表示疑问的“是否”就使用whether；
