我通常每天至少使用電腦八小時 求英文翻譯... How often does Jusitn study Chinese? (如果他每天都有讀) 我可以回甚麼?可以這樣寫嗎? He studies Chinese every day. 還是要寫每周每天啊?那要怎麼寫ㄚㄚㄚ~~~?

頻率副詞 "usually / often / sometimes" 只是輔助詞語, 對 「主語 + 動詞 + ... 」句子 的結構無直接影響！

我通常每天至少使用電腦八小時
I usually use the computer at least 8 hours a day.
I usually spend at least 8 hours on the computer every day.
___________________________________________________
How often does Justin study Chinese?
He studies Chinese every day.
如果要寫每周每天：
He studies Chinese daily every week.

A:Does your mother watch TV after dinner?

B:Yes, sometimes. ................................ (簡答)
B:Yes, she sometimes does. ................................ (簡答)
B:Yes, she sometimes watches TV after dinner. ................................(詳答)

(A)"often" is adv of frequency occupying mid-position with the verb(=study), that may occupy front-position or end-position
Hence the question:-How often does Justin studies Chinese ?
eg:-He studies Chinese every day----simple.
eg:-He very / quite "often" studies Chinese daily every week.------detailed with another adverb of frequency; "very / quite"occupying front-position.
(B)Yes, sometimes.-------simple answer; sometimes is adv.=at some times
----Yes, she sometimes watches TV after dinner.------detailed answer.

1. 我通常每天至少使用電腦八小時 求英文翻譯... # I usually(頻率副詞) use(動詞) computer at least eight hours a day(時間頻率副詞通常置於句尾). ←← # 頻率動詞置於動詞之前。
2. How often(頻率副詞的疑問詞置於句首) does Jusitn study Chinese? (如果他每天都有讀) 我可以回甚麼?可以這樣寫嗎? He studies Chinese [every day(時間頻率副詞通常置於句尾)]. ←← 這是適當的。還是要寫「每周每天」啊? ←← # 英文華文都不能如此說。那要怎麼寫? ←← # [每週：every week]、[每天：every day]。
3. A：Does your mother watch TV after dinner(時間副詞)?
B:Yes, ...... (以sometimes先簡答、再詳答) 後面要怎麼寫，我不太懂頻率副詞要放哪裡。
B：Yes, sometimes(頻率副詞).
B：Yes, she sometimes(頻率副詞) does.
B：Yes, she sometimes(頻率副詞) watches TV after dinner(時間副詞).
B： Yes, she watches TV after dinner(時間副詞).
B：Yes, she does(強調語) watch TV after dinner(時間副詞) every day(時間頻率副詞).

各位的答案都很棒，謝謝~~
