Question

have access to后加动词的什么形式

Answer 1

1、have access to 后面只能跟物(的名词)，或人(称代词)，不能使用动词。
2、如果是人，表示有机会（或权利）接近某人；
She has access to the president face to face before she's going to dies.
3、如果是事物，表示有机会使用某物，亦或有接近、进入某地的方法、途径。
Gaining/Having access to the write house is her lifetime dream.
4、上述两个例句，多少也说明了为什么不用动词，因为没有必要，就象画蛇添足一样。
