动词的时态剖析.ppt

?　考点八　过去将来时(would do, was/were going to do) 规则1：表示从过去某时看来将要发生的动作或状态或过去的意图打算(主要用于宾语从句中)。 She was sure she would succeed. 规则2：表示过去经常发生的动作。 　　When he was young, he would go swimming. 【温馨提示】 would与used to的区别：would只表示过去，不涉及现在；而used to表示“过去常常”要与现在比较，即现在不是这样了。 规则3：过去将来时对应的时间状语常见的有：the following month, the next week等。 ?　考点九　几种易混时态的辨析 　　 1．一般现在时与现在进行时 　　一般现在时表示经常性的、习惯性的或状态性的行为。 而现在进行时则具有进行性、未完成性和暂时性的特点。 On the wall hangs a picture painted by Qi Baishi.

Flight 4026 ___________ (将起飞) at 18:20.(take) 3. It ________________(没有下雨) outside. Let’s go and play football. (rain) is taking off takes off is not raining 2．一般过去时和现在完成时 一般过去时所表达的事件与现在无关。而现在完成时则强调对现在的影响和结果。 I stayed in Beijing for five days. Then I went to America.(I am not in Beijing now. ) I have stayed in Beijing for five days and havent decided where to go next.(I am still in Beijing now and dont know where to go next.) 4.
