4、 首先，我们将本模块中出现的有代表性的句子归纳如下：,1. 一般现在时 一般现在时可以用来表述或说明某一事物的特性，如上面表格的(1)；描述现在的状态，如(2)。一般现在时还用来描述经常发生的事情及真理，例如： Thousands of people visit Beijing every year. The sun rises in the east and sets in the west.,注意: 1. when, until, as soon as等引导的时间状语从句和if引导的条件状语从句中, 若主句是将来时或祈使句, 从句则要用一般现在时表示将来。 2. 列车时刻，飞机航班用一般现
5、在时。,2. 一般过去时 一般过去时可以用来表述过去某个时间发生的事情或行为，如上面表格中的(3)。一般过去时还可以用来描述事物过去的状态或过去经常发生的事情，例如： I was very thin in my childhood. I got up very early when I was a college student.,注意： used to是过去时, 表示过去常常。 e.g. I used to take a walk in the morning. 我以前常常早晨散步。,3. 现在进行时 现在进行时可以用来表述现在正在发生的事情或正在进行的行为，如表格中的(4)。现在进行时还可
6、用来表示已经安排好的活动和事件。例如： My elder brother is coming tomorrow. We are having a meeting tomorrow morning.,注意： go, come, leave, fly等表示位移的动词的现在进行时可用来表示将来。 e.g. She is flying to London tomorrow. 她明天将飞往伦敦。,4. 过去进行时 过去进行时表示在过去某段时间内正在发生的事情或行为，如表格中的(5)。从例句可以看出，过去进行时常常以一个过去的行为或时间为参照。例如： I was having breakfast when
7、 he telephoned me. What were you doing at eight oclock yesterday evening?,注意： while从句中的动词只能是延续性动词, when从句中的动词延续性动词非延续性 动词均可。 e.g. The phone rang while / when Mr. Wang was sleeping on the sofa. 王先生正在沙发上睡觉时, 电话铃响了。,5. 一般将来时 一般将来时表述的是发生在将来的事情或行为以及未来的状态，如表格中的(6)。在表示对将来的预测时(没有相关迹象表明某事必然会发生的情况下)，will和be g
8、oing to可以互换。例如： It will / is going to be a rainy day tomorrow.,但在其他情况下，be going to更强调计划性，而will着重表达个人意愿或想法。例如： He is going to spend his vacation in Hawaii. I will give you the information when I get it.,注意： there be结构的一般将来时常用There is /are going to be或There will be表示。 e.g. There is going to / will be
9、a film this evening. 今晚将有一场电影。,6. 现在完成时 现在完成时与一般过去时所表示的行 为都发生在过去，但是两者表达的重点不同：一般过去时表述过去的事情，现在完成时则强调过去的行为对现在的影响，如表格中的(7)。看对话，对比两种时态： A: Have you seen the film? B: Yes, I have. A: When did you see it? B: Last night.,从对话中可以看出，当谈话重心在过去的时间、地点或人物，而不是事件的结果或影响时，要用一般过去时。反之，如果我们要强调的是过去的事情对现在的影响，则应该用现在完成时。 现在完成
10、时还表示某个状态从过去某个时间开始，一直持续到现在。例如： I have lived here for a long time. I have been ill for a week.,注意： have been to 曾去过某地, 表示一种经历have gone to 到某地去了 e.g. My father has been to Shanghai twice. 我父亲去过两次上海。 Mr Wang isnt here. He has gone to Dalian. 王先生不在这儿, 他去大连了。,各种时态中一般疑问句和否定句的构成 (以do为例)： 1. 一般现在时 一般疑问句式：Do
