Unit 2TravellingGrammar(II )
【学习目标】1.使用have gone to/have been to。2.使用for与since。
3.延续性动词与瞬间动词的区别。
【学习重点】for/since与现在完成时的连用。
【学习难点】延续动词与瞬间动词。
学习流程【学习准备】自主探学,发现问题
一、 have/ has gone to与have/ has been to/ have/has been in
have/ has gone to 表示“去某地了” 或在去某地的途中”人现在不在这里;have/ has been to 表示“某人曾经去过某地”并且已经回来。常与次数连用。 have / has been in 后常跟一段时间,表示在某地呆了一段时间,现在还在那儿 *She has gone to Shanghai.她去上海了。(此人已不在此地)
* She has been to Shanghai.她去过上海。(此人已不在上海了)
* She has been in Shanghai in for ten years. 她已经在上海10年了。(此人现在还在上海)
1. A: Where’s Jim, Li Lei? B:He ______________his school library.
2. The Greens _____________China for three years.
We _____________ the Great Wall twice. It’s very beautiful.
二、当现在完成时和表示一段时间的时间状语连用时,肯定句中要用延续性动词, 而不能用短暂性动词。
表一段时间的时间状语有1.since自从…以来,
注:since + 过去点时间 since+ 一段时间 + ago= for +一段时间 since+ 一般过去时态的从句
They have read English since 7 o’clock./They have been friends since two years ago. He has lived here since he was born.
for +一段时间up to now一直到现在,so far到目前为止, 迄今为止
in the last \past 5 years在刚过去的五年里,these days\ weeks\ months\ years这几天/年…..over the past century在过去的一百年里
They have stayed in Shanghai for a month.他们已经在上海呆了一个月了。
Our hometown ___________(change) a lot in the past 5 years.
We ______________(learn) over two thousand English words so far.
切记有些动词是非延续的,跟一段时间连用时必须用延续性动词,如是短暂性动
