为什么用run不用have ?

2:why havn't you started writing ?
I__have been considering__what to write about,sir?

为什么不用have considered??

Answer 1

run可以表示组织生活或工作的方式(to organize the way you live or work)如:
Some people run their lives according to the movements of the stars.
有些人根据星星的运行来调整或组织他们的生活方式.

在你的句子中，就是强调青少年们要自己学会如何组织和支配他们的生活.

have been doing是现在完成进行时,表示从过去到现在一直在延续进行的动作,并且还将继续下去,如:
I have been working for a whole morning.今天早上我一直在工作.

run 有经营的意思，更确切。
have been doing是现在完成进行时，表示从过去某段时间到现在一直进行某个动作。此处强调一直在想，已经有很长时间了。

Answer 4

2 have been considering完成进行时，表示一直在考虑，
