复合句还是并列句

复合句还是并列句

请看下面一题，是考查复合句还是并列句？

If I’m mistaken, _________ you are mistaken too.

A. so                        B. and                      C. or                        D. 不填

空格前 if 引导的是一个条件状语从句，它暗示整个句子为复合句；而so, and, or 为并列连词，无论选哪一个，都表明整个句子为并列句，从而导致前后矛盾，所以A、B、C均不能选择。此题正确答案选D，you are mistaken too 为主句。又如：

(1) If wishes were horses, _________ beggars would ride.

A. and                      B. so                        C. or                        D. 不填

(2) When the last prize had been awarded _________ everybody cleared off.

A. and                      B. so                        C. or                        D. 不填

(3) Just before I left London, _________ I sent him a telegram.

A. and                      B. so                        C. or                        D. 不填

(4) After they had each said a few words, _________ Lloyd George took the floor.

A. and                      B. so                        C. or                        D. 不填

答案均选D，空格前分别为 if, when, before, after 引导的状语从句，空格后为句子主句。
