从20世纪80年代起,比尔 • 盖茨每年都要进行两次为期一周的 “闭关” 。
This is from the Standard Course Book of HSK 5, chapter 26.
I want your help in the literal translation of this: 比尔 • 盖茨每年都要进行两次为期一周的 “闭关” 。
I have reached on this point: 比尔 • 盖茨(Bill Gates)每年(every year)都要进行两次为期(??)一周(one week)的 “闭关” (seclusion).
As you can see I cannot understand this 都要进行两次为期
都:Is it just an emphatic character?
要:I know it means to want or will. But here?
进行:Does it mean to conduct? To carry out?
两次:Does it mean twice?
为期: Does it mean deadline?
How to make all this make sense here?
