If I say I want to touch base with you, I will talk to you from time to time about something we plan to do. I might say I touched all the bases if I did what is necessary to complete a job or activity. And if I covered my bases I was well prepared. 如果我说I want to touch base with you,意思是我会就我们计划做的一些事情不时和你交谈.如果我做了某项工作或活动所必须完成的所有事情,我可能会说 I touched all the bases.如果I covered my bases,意思是指做好了充足准备.
