[請益] each和then的用法
1.each
each的用法讓我很困惑 @@
(1)Each of the students has to write a paper.
(2)Each student has to write a paper.
(3)The students each have to write a paper.
實在不知道上面這三句的單複數用法是為什麼,是一種習慣用法嗎?
這三句的意思都是一樣的嗎?
假如有個活動,每個學生都拿到3個蘋果,每個老師都拿到5個蘋果
(4)The number of apples of each student and each teacher is/are
3 and 5 respectively.
那這樣是要用is還是are呢?
還有..each student and each teacher
如果把第二個each省略掉的話,變成each student and teacher
這樣還能夠表達"每一個"老師的意思嗎?
2.and then和then的差別
在描述一件事情的步驟時,例如
(5)We first go to the classroom, (and) then go to the gymnasium, finally,
we go to the park.
這句話描述了三個步驟,第二步go to the gymnasium
那麼什麼時候用then,什麼時候用and then呢?
以上問題,麻煩大家解惑了,謝謝
