(I)
He has been a student at Oxford University for the past year.
^^^^^^^^^^^^^^^^^
請問這裡表達的是 "從過去到現在的1年" 嗎?
(II)
During this time, he (a)has discovered common interests among his classmates.
^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^
(b)discovered
^^^^^^^^^^^^^
請問用(a)的話,表過去到現在的這段時間~ ;
(b)的話,表過去某段時間~
這樣講對嗎?
(III)
When the teacher is talking in class, you can't stand up.
這個句子對嗎?
我google了一下,大部份只看到的就是有關when/while用法,
或是when後面為省略主語而接的現在分詞!
是否有其它用法、還請各位先進指教!
Thank you!! ^ ^
