高中英文句型問題

解答: Most English teachers suggest that they should keep practicing English at college,especially their listening and speaking skills.

請問:

(1)最前面可以改成"Most of"嗎?
如果你要改成most of，後面要變成the English teachers
也就是你可以兩者擇一，要不說most English teachers，要不就說most of the English teachers.

(2)最後面可以改成"...especially the skills of listening and speaking."嗎?
我覺得可以。

(3) 為何skills要加複數? "技巧"可以數量化嗎?
可以。
而且這邊指聽的技能&說的技能，所以可以加S
即使你只說listening/speaking skill(s)，其實也可以加S

2.台灣學生在高中畢業的時候，將已經學了至少六年的英文。

答:Students in Taiwan will have learned English for at least six years by the time they graduate from senior high school.


問:

(1)前面不能用"The students"嗎?
可以不用加the，the通常要前面出現過才能加，如：
There are ten students in the classroom. The students are all male.
教室裡有十個學生，十個(the students)全都是男的。

(2)Students in Taiwan will have learned for at least six-year English by the time they graduate from senior high school.
這個句子沒有問題。
可以把句子切成兩部分來看，
1.Students in Taiwan will have learned for at least six-year English
台灣的學生到時候就已經學了至少六年的英文

2.by the time they graduate from senior high school.
到了他們高中畢業的時候

按照中文的邏輯，你可以先讀2，再回頭讀一，或許就會比較清楚。
