attender

attend, attend to

这两者都可译为“出席”,但含义上有区别：attend指“人”去了, attend to则进一步指“心”去了,介词to在这里指“集中注意力于…”,例如:

He attended school, but didn't attend to his lessons.

他去上学,但不把功课放在心上。

He did attend the lecture this morning, but somehow he did not seem to attend to it.

今天上午他的确去听课了,可是不知 怎的他似乎心不在焉。

attend on, attend to

这两个短语的区别是：

1.attend to是“照料”的意思, attend on是“侍候”的意思。介词to表示对象,而on则进一步表示目的,含有使其满意的意味。

2.attend on的宾语只是人, attend to的宾语可以是人,也可以是物。

3.attend to还含有“认真听”“认真干”的含义。

attend, be present

这两者都可译为“出席”。二者的区别是：attend强调的是过程, be present强调的是状态。例如:

I attended a meeting this morning.

今天上午我参加了一个会议。

He was present at the scene.

他当时在场。
