“主语+介词短语”作主语时的主谓一致

“主语+介词短语”作主语时的主谓一致
 
按英语习惯，介词短语通常不用作主语，所以当主语后跟有一个介词短语时，其后谓语动词的数只与介词短语前面的主语保持一致，而与介词短语无关。如：
A woman with two children has come. 一位妇女带着两个孩子已经来了。http://yingyu.chazidian.com
Everybody but you knows what was happening. 除了你以外，人人都知道出了什么事。
The teacher, together with some of his pupils, was cleaning the room. 教师和他的一些学生一起在打扫教室。
以下两例中的 as well as 也可视为介词，其后谓语与 as well as 前面的主语保持一致：
The students as well as the teacher were present at the meeting. 学生和他们的老师出席了会议。
I as well as they am ready to help you. 不仅他们愿意帮助你，我也愿意帮助你。
