有一读者问：有这样一类的句子：
(1)We sang and danced all night.
(2)We were talking and laughing.
(3)Jimmy fell off his bike but was unhurt.
(4)The old man dropped his head and began to murmur to himself my father's name.
有人说上述句子都是并列句；但也有人说句中的两个谓语动词是并列谓语，所以上述句子都是简单句。到底应怎样看，请赐教。
一权威著作说，上述句子既可称作含并列谓语的单个句子，亦可称作含两个分句的并列句，只是分析方法不同而已。它所给的典型例句之一是：
(5)Peter ate the fruit and drank the beer.
此含并列谓语的句子可以扩展为一含两个分句的并列句如下：
(6)Peter ate the fruit and he drank the beer.
但我们认为，为了教与学的方便，将上述句（1）至句（5）统统称作含有并列谓语的简单句较好，而句（6）才应称作含有两个分句的并列句。拙编的《英语语法手册》与《高级英语语法》实际上都是如此处理的。关于上述问题，如有兴趣，可参阅英人夸克等著的《英语语法大全》（A Comprehensive Grammar of the English Language ）中的有关部分。
