不同时态综合复习(一)
一、四类基础时态系统精讲
(一)整体概述
本单元整合一般现在时、一般过去时、一般将来时、现在完成时四大核心时态,依托旅行场景区分动作发生的时间落点;其中现在完成时为本单元重难点,用来搭建过去动作与当下现状之间的联系。
1. 一般现在时
· 基本结构
主语为三单:系动词 is;谓语动词 + s/es
主语非三单:系动词 am/are;谓语动词原形
· 标志词:every 系列、often、usually、always、seldom、sometimes
· 用法:描述日常出行习惯、客观常识、事物固有特征
· 例句:Many tourists visit Qufu every year.(每年都有游客前往曲阜游览)
2. 一般过去时
· 基本结构:系动词 was/were;谓语动词变为过去式
· 标志词:yesterday、…ago、last…、in + 过去年份
· 用法:动作完全发生在过去,和现在不存在任何关联,仅陈述过往经历
· 例句:I travelled to the Terracotta Army three years ago.(三年前我去过兵马俑)
3. 一般将来时
两种常用结构
(单纯表达将来动作)
(带有计划、预判含义)
· 标志词:tomorrow、next…、in + 一段时间、in the future
· 用法:尚未发生的旅行计划、后续安排
· 例句:We are going to climb the Great Wall in two weeks.(两周后我们打算去爬长城)
4. 现在完成时
(1)基本句式
肯定:
否定:
疑问:
使用规则:主语 he/she/it、单数名词、单人专有名词用 has;其余主语统一使用 have。
两层核心语义:
①过去发生的动作,结果留存至现在;②动作自过去起始,一直持续到当下。
(2)四大时态对比表格
时态
基础结构
标志性时间状语
核心用法
例句
一般现在时
am/is/are;动词原形 / 三单
every…, usually, often, always, seldom, on Sundays
客观真理、长期出行习惯、事物固有特征
Many young people travel every holiday.
一般过去时
was/were;动词过去式
yesterday, …ago, last…, in + 过去年份、朝代
动作彻底发生在过去,和现在不存在关联
He visited Qufu three years ago.
一般将来时
will do / be going to do
tomorrow, next…, in + 一段时间,in the future
动作尚未发生,代表往后的出行规划
We will visit traditional cultural sites soon.
现在完成时
have/has done
already, yet, ever, never, just, before, so far, up to now, since + 时间点,for + 时间段
过去动作关联现在;动作从过去延续至现在
I have visited the Great Wall twice.
(二)现在完成时三大必考重难点
考点 1:have been to /have gone to /have been in
1. have been to:曾经到访某地,如今已经返回,常搭配次数 twice、three times
例:I have been to Xi’an twice. 我去过西安两次。
2. have gone to:动身前往某地,人此刻仍在目的地,还没有归来,不常用于一、二人称
例:She has gone to appreciate Hanfu shows. 她前去观看汉服演出了。
3. have been in:在某地长期逗留,后面搭配 for、since 引导时长
例:They have been in Jinan for five years.
考点 2:短暂性动词转换延续性动词(高频易错点)
for、since 引导一段持续时长时,谓语动词必须选用延续性动词,瞬间动作无法进行持续。
高频转换清单:
come/go → be in;buy → have;leave → be away;die → be dead;borrow → keep;join → be in
例句:
He left China five years ago.(一般过去时,可用瞬间动词)
He has been away from China for five years.(现在完成时,不可使用 has left)
考点 3:since 与 for 的辨析
· since + 具体时间点:since 2016,since last spring
· for + 一段时长:for ten months,for two weeks
(三)拓展衔接:现在完成时被动语态
结构:
例句:Many ancient buildings have been protected well. 许多古建筑已经得到妥善保护。
