` in ` is the correct answer.

Answer 4

请相信 japanyuji, 答案是d.

如果你答了a, 那你真的是over了！

Answer 5

The answer is

a. over 超過

I need to sleep _over_ 30 min ......我需要睡超過30分鐘
(over a certain of time......e.g. over 2 years )

b. between ....兩點(時間之間)......e.g. between 01:00 and 06:00

c. on ....a day ......e.g. on Sunday

d. in ... a (longer) period of time......e.g. in July

對於 preposition 用於時間..
-> at ...at a point of time ......e.g. at 12:00

P.S. derek_leekingon
也答過 "at/on/in/....係咩時間用?點用?"

at on 同in 分別都係時間介詞
即係preposition of time
at on in有唔同既運用方法

1. at-- 表示準確的時間或節日
e.g at 4:00 , at noon, at this moment, at present, at midnight
at sunset, at dawn, at Christmas, at New year

2. on-- 表示一個特殊的時間或日期
e.g on her birthday, on Chirstmas Eve, on Thrusday, on Friday morning,
on a cold day, on September 10, 1994

3. in-- 表示某一時間或時段
e.g in 1990, in March, in the morning, in the past, in the future, in the afternoon
in a week, in two months

I've just found,e) 另, 在未說明具體 (時刻) 或 (日期) , 而只是說 (未來的某個時候)的場合, 亦要用in 來表達Eg: She is coming here in an hour.He wants to be a detective in the future.http://hk.knowledge.yahoo.com/question/?qid=7006050901404Is that both a and d correct? or just d?

I've just asked a English teacher,She said "d" should be the best answer!! (and I agree)although "a" is grammatically correct but the meaning is so strange..
