point to 和point at 有什么区别

point at,point to和point out的意思都与“指”有关,但还是有一定区别.

point at习惯上表示指向离说话人较近的事物,意为“指着”,at是介词,着重于指的对象.

point to多用来表示指向离说话人较远的事物,意为“指向”,to也是介词,着重于指的方向.

my home.”

他指着河对岸的房子说：“那是我家.”

point out表示的是给某人指示方向,要点或错误等,意为“指出”,out是副词.

老师指出我作业里的许多错误.

1.一般情况下point at和point to可互换,但事物名词作主语时,用point to要常见些.

The building points to the east.这所大楼朝东.

2.point at可分开使用,point后直接跟名词或代词作宾语,at表示方向,而point

to却没有这种用法,但它还表示“显示、说明”的意思.

They pointed their guns at her head but she was not afraid.

他们把枪指着她的头,但她并不害怕.

All the facts point to the same conclusion.所有事实都说明同样的结论.
