AND能联结两个或两个以上部分，形成复合主语。

　　◆ Joe AND his friends ARE going to the beach.

　　◆ Mathematics, history, AND science ARE mandatory high-school subjects.

　　请注意，这种复合主语的谓语动词用复数采取复数形式。其他许多单词和短语也都有and的功能。例如：

　　◆ along with Polly / accompanied by me / in addition to surgery / together with a tie / as well as the mayor / including salt and pepper

　　这种类似的词也是句子中可删除的成分。这种类似的词和And有时并不同，因为他们在句子中并无实际成分仅做修饰，并不能影响主语的数量。

　　◆ Joe, as well as his friends, IS going to the beach.

　　◆ Mathematics, in addition to history and science, IS a required subject.

　　但是如果是AND的话就会改变句子的主语变为复数，所以请记住，类似于AND的添加词并不改变句子的单复数。
