急,这句用的什么语法
Professor Peter Newman compared Sydney and Beijing,and pointed out that .
我印象中A,and B中,AB都应该为有主谓的句子.(Professor Peter Newman compared Sydney and Beijing,and HE pointed out that .我认为这句才是语法上没错误的)
不知道我以上列举的那个句子语法上有什么错误吗?还是其中有什么我不知道的语法存在?
是复合句，比如：
I get up early and eat my breakfast.
I get up early,and I eat my breakfast.
I am cleaver and he is stupid.
I am cleaver,and he is stupid.
以上都行，我的问题是形如：I am ,and eat my breakfast.是什么语法呢？

Answer 1

后面的and 连接的是两个并列的谓语动词compared 和 pointed.没问题的.
你说的那个语法现象是这样的：两套完整的主谓结构要用and或其他连词连接.
例如：She won the game,but I lost.
不能说：She won the game,I lost.
但如果两句之间是句号,就可以不用连词了.
