Question

有一组英语近义词没搞清区别，请大家帮忙解释一下区别，跪谢！

so that , so as to , lead to , causes , aim at
重要的是用法上的区别，谢谢！

Answer 1

so that 是以便的意思
e.g I learn English so that I can speak with Americans
我学英语以便我与美国人交流

so as to 与so that 意思一致，用法不同 to 后接 动词短语
e.g.I learn English so as to speak with Americans

lead to 导致
e.g.THe lack of exercise leads to all kinds of diseases
缺乏运动导致各种疾病

cause 引起
e.g.The lack of exercise causes all kinds of diseases.
缺乏运动引起各种疾病

(个人认为从用法上意义上没什么区别，做题时翻成中文带进去看哪个合适就行了)

aim at 旨在 针对
e.g.We aim at quality rather than quantity.

我们的目的是重质不重量。

Answer 2

so that 是为了 后面加从句
so as to 也是为了，后面加短语
lead to 导致 可以使好的事也可以是坏的事
cause 是引起
aim at 是目标是，旨在
