2、由as well as, with, along with, like,together with, rather than, except, but, including, accompanied by, plus,besides, in addition to, no less than 等引起的结构跟在主语后面，不能看作是并列主语，该主语不受这些词组引导的插入语的影响，主语如是单数，其谓语动词仍然用单数形式。例如：
　　The reading course book, plus its reference books, is helpful tocollege students.
　　教材加上参考书对大学学生是非常有益的。
　　The man together with his wife and children sits on the sofawatching TV.
