（1）時間副詞的種類

1）表示確切時間的副詞

yesterday　today　now　tomorrow

2）表示不確切時間的副詞

3）表示時間的副詞短語

a week ago　three months ago　at once　in a while　in recent days

（2）時間副詞在句中的位置

1）表示確切時間的副詞和表示時間的短語一般不能用于句中，它們可用于句首或句末。用在句末更常見（尤其是在祈使句中只能用于句末）。

a. Tomorrow I'm leaving for Beijing on a business trip.

明天我去北京出差。

可以說：I'm leaving for Beijing on a business trip tomorrow.

不說：I'm tomorrow leaving for Beijing on a business trip.*

b. I saw him a week ago. /A week ago I saw him.

不說：I a week ago saw him.*

c. Come to my office this afternoon.

不說：Come this afternoon to my office.*

2）表示不確切的時間副詞可用于句首、句中或句末。例如：

a. I've recently been busy.

b. Recently I have been busy.

c. I have been busy recently.

d. Very soon we'll be there.

e. We'll very soon be there.

f. We'll be there very soon.

3）before, early, immediately, late通常位于句末。例如：

a. I have never heard such a story before.

b. He came to school late.

總體來看：

1）時間副詞一般可用在句首，也可用在句末。而通常我們把時間副詞放在句末較為保險。

2）能用于句中的時間副詞不多。

3）在祈使句中時間副詞只能用于句末。
