要掌握英语的时态和语态，必须掌握好英语中的助动词(do,
be,
have)和时间状语这两个核心问题。
1、一般现在时
主要用来表示人、事物的现在状况和特点；表示经常或习惯性的动作，句子中常有often,
always,
from
time
to
time
等时间状语；
表示客观规律和永恒真理等。
2、现在进行时
表说话时或目前一段时间内正在进行的活动：或表感情色彩，加强语气。与频率副词，如always，constantly，continually，again等连用表示说话人的某种感情色彩（赞叹、厌烦、埋怨等）。
3、现在完成时
表示动作发生在过去，完成在过去，但强调与现在情况仍有联系，其结果或影响仍存在。现在完成时有一些标志性的时间状语：
4．一般过去时
表在过去某个特定时间发生且完成的动作，或过去习惯性动作，不强调对现在的影响，只说明过去。常跟明确的过去时间连用，如：yesterday;
last
week;
in
1945,
at
that
time;
once;
during
the
war;
before;
a
few
days
ago;
when,
注意：
5.
过去进行时
表示过去某个时间点或某段时间内正在发生的动作。
6.
过去完成时
表示过去某个时间之前已经完成的动作，即过去完成时的动作发生在“过去的过去”，句中有明显的参照动作或时间状语，这种时态从来不孤立使用
(
before,
after,
by,
up
till
)
7.
一般将来时
表在将来某个时间会发生的动作或情况。常和tomorrow,
next
year,
in
2008等表示将来的时间状语连用，其表现形式多达5种。
8、将来进行时
表将来某个时间正在发生的动作，或按计划一定会发生的事情。
9、将来完成时
表在将来某时刻之前业已完成的事情，时间状语非常明显。
