延续性动词
拓展
延续性动词和非延续性动词的用法
1. 含义：
延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。
非延续性动词也叫终止性动词、瞬间动词等，表示不能延续的动作，这种动作发生后即刻停止。
2. 用法：
①常见的延续性动词有learn, work, live, know,
walk, watch, sleep, stay, wait, keep等。
延续性动词可以用在现在完成时中与表示一段时间的状语连用，如how long，for＋时间段，since＋过去的时间点，since引导的时间状语从句(一般过去时)，since＋一段时间＋ago等。
②常见的非延续性动词有open, close, die, begin,
come, go, borrow, lend, buy, move等，可以用
于现在完成时，说明某个动作的结果还存在，
但不能与表示一段时间的状语连用。
③在否定句中，非延续性动词可以与表示一段时
间的状语连用。
例：我已经有三个星期没有收到我朋友的来信了。
I haven’t heard from my friend for three weeks.
3.非延续性动词（短语）与延续性动词（短语）
的转换：
①直接转换成延续性动词
buy → have borrow → keep put on →wear
catch a cold → have a cold
例：She caught a cold three days ago.
=She has had a cold for three days.
②转换成“be＋形容词/副词/介词/名词”等
come/arrive/go → be in/at
begin/start → be on
finish/end/stop → be over open → be open
die → be dead leave → be away
close → be closed fall asleep → be asleep
fall ill → be ill become → be
join → be a member of/be in
come back → be back
go to school → be a student
例：They got married two years ago.
=They have been married for two years.

教学过程
Step 1 Group work 完成下列句子。1. — How long have you had that bike over there — I’ve had it for three years. 2. How long has his son owned the train and railway set He’s owned it since his fourth birthday. 3. Have you ever played football Yes, I did when I was little, but I haven’t played for a while now.Step 2 现在完成时现在完成时的持续性用法现在完成时还可表示过去某一时间开始并一直持续到现在(包括“现在”在内)的动作或状态，该用法中的动词多是延续性动词，常见的时态标志词有since, for等。1. since意为“自从……以来”, 它既可作介词，也可作连词。作介词时, 后接表示过去的时间点, 表示某事开始的时间；作连词时, 引导时间状语从句, 从句常用一般过去时。如： We have been here since last Sunday / two years ago. Mr. Jones has worked here since he was twenty-five.2. for作介词，后接一段时间，表示一个动作或一种状态已经持续了多长时间。如： I have studied here for three years. She has been away for five days.注意：1. 对since和 for引导的时间状语提问时, 常用how long。如： Jane has learned to play the piano since two years ago. (对划线部分提问) How long has Jane learned to play the piano 2. 在现在完成时中，含有for和since的句子可以相互转换。如： They have lived here for five years. =They have lived here since five years ago.3. 在现在完成时中，表示短暂意义的动词(如come和see)在肯定句和一般疑问句中不能和表示一段时间的时间状语连用，但在否定句中是可以的。如： Mike has come to London for three weeks. (×) They haven’t seen each other for ages. (√)短暂性(短语)动词与延续性(短语)动词和与表示状态的短语之间的转化1. 有些短暂性(短语)动词可转化为相应的延续性(短语)动词。常见的有： become → be borrow → keep buy → have / own catch a cold → have a cold come → stay put on → wear go to sleep → sleep move to → live in2. 有些短暂性(短语)动词可转化为表示状态的短语。常见的有： leave → be away begin / start → be on die → be dead finish → be over join → be in / be a member of fall asleep → be asleep marry → be married come / arrive here → be here中考链接1. —It's time to work now. —OK.
