There’s some doubt __________he’ll keep his promise.A.whether | B.when | C.that | D.which |

答案
A |
解析
试题分析:doubt"疑惑;怀疑” ,在肯定句中doubt多接whether (一般不用if代替) 引导同位语从句。在否定句中,用that引导同位语从句。故选A。句意:有点怀疑他是否能遵守诺言。 点评:同位语从句属于名词性从句,名词性从句中缺主语,宾语,表语,定语。故使用连接代词What,which,who...,缺状语时,使用连接副词how,when,where,why等,如果不缺成分,使用that,if 或whether。If 不能引导同位语从句。That在名词性从句中不充当任何成分,没有任何意义,只起引导作用。 |
