Question

英语句子连接词：Most animals have nervous systems,sense organs,and s

Answer 1

因为这里的and are capable of securing,ingesting和前面的have nervous systems,sense organs,and specialized modes of locomotion共用了一个主语,是来说明主语所处的状态和特征,并不是对前面一句话的补充说明或是限定修饰

and digesting food中的and 是作为并列连词,连接的是3个动名词,就不能换成which

试着比较下以下的两个句子.

They bought two bikes,and both of them are expensive

They bought two bikes,both of which are expensive.

第一个句子是一个并列句,而第二个句子是一个含有非限定定语从句的复合句
