常与表示频度的时间状语连用。如often, always, sometimes, usually, once a week, often 等。如：

The earth goes around the sun. Guangzhou is situated in the south of China. The harder you study, the better results you will get. 2.一般过去时
含义：表在过去时间里所发生的动作或存在的状态。 结构：主语 + 动词的过去式
常用的时间状语有：yesterday, last week, an hour ago, at that time, in 1982 等。另外还有after, before, when引导的时间状语从句。如： I wrote a letter last night.
考点：used to + do 表示过去经常但现在已不再维持的习惯动作。to为不定式符号，后接动词原形。
比较：be / become / get used to + doing 表示习惯于
He used to smoke a lot. He has got used to getting up early. 3. 一般将来时
含义：表示在将来某个时间要发生的动作或存在的状态。 结构：主语 +will / shall / be going to +动词原形
常和表示将来的时间状语连用。如tomorrow, next year, in 2008，in a few days, one day等，其表现形式多达5种。
考点一：一般将来时总是用在一些时间状语从句或条件状语从句的主句中。 We will begin our class as soon as the teacher comes.
(主句用一般将来时，从句中一定要用一般现在时替代一般将来时。)
考点二：某些表示短暂性动作的动词如arrive, come, go, leave, start等，用现在进行时形式表示将来。
I am leaving for Beijing tomorrow.
考点三：―祈使句 + and / or + 句子‖，这种结构中and后面的句子谓语用一般将来时。 Use your head and you will find a way.
考点四：―be going to + 动词原形‖，表示打算要做的事或可能要发生的事。 ―be about to + 动词原形‖表示按照预定计划或打算准备着手进行的动作。 ―be to + 动词原形‖表示必须、必然或计划将要做的事。 They are to be married in May. 4. 现在进行时

考点二： 表示在最近按计划或安排要进行的动作(这时多有表示将来的时间状语)。 Marry is leaving on Friday. 5. 现在完成时
含义：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。 结构：主语 + have / has +动词的过去分词 ①：for + 时间段；since + 时间点
They have studied English since 1985.
②：常见的不确定的时间状语：lately, recently, just, already, yet, up to now; till now; so far,
these days。如：Has it stopped raining yet?
③：英语中有些常用的单词如：come, go, begin, start, finish, find, die, buy, borrow, sell, put
on, get up, arrive, receive, become为瞬间动词，不能和表示一段时间的for短语和since短语连用，也不能用于how long引导的疑问句中。比如说，我们可以说She has come back. 不能说She has come back since last week. 这些瞬间动词常常与它相对应的可以表示时间段的词语转换。如：
become ---- be borrow ---- keep begin (start) ---- be on buy ---- have open ----be open die ----be dead
How long can I keep this book? (句中keep表达borrow―借‖的意思。)
此外，瞬间动词还常常用It is / has been + 一段时间+ since 从句（从句用过去时） 来表示从某事情发生以来已有一段时间了。
It is / has been two years since my brother joined the army. 我哥哥参军已经有两年了。 ④：现在完成时与过去时的区别
现在完成时表示过去发生的动作结现在的影响和结果，强调节器的是现在，不与具体的过去时间连用。但一般过去时只表明过去的动作或状态，与现在无关系，常与具体的过去时间连用。
He has lived in New York for eight years. 他在纽约住了有八年了。（他仍在纽约） 6．过去进行时

The boy was doing his homework when his father came back from work. He was taking a walk leisurely by the lake when he heard someone shouted for help. What were you doing at nine last night?
The radio was being repaired when you called me. 7、过去完成时
含义：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。 结构：主语 + had +动词的过去分词
By the end of last term we had finished the book. They finished earlier than we had expected.
