一般现在时与现在进行时使用频繁,应理解如下两点。
一、准确理解两种时态的主要含义:
A、一般现在时
1、表示事物的本质特性或客观存在,没有时限性。
The table ____ soft。 (feels ) 表特性特征。
Japan ___ to the east of China。 (lies ) 表客观事实
2、现阶段经常性、习惯性的行为,可带频率时间。
The shop closes at 7:30 p.m.
Father doesn’t smoke. (习惯 )
3、表说话时的状态,感觉或结果,一般用状态动词,如It doesn’t matter.
Does it hurt? (感觉结果)
4、特殊用法:
-在条件、时间、让步从句中用现在时代替将来。
-If you go there, I’ll help you.
—用在begin ,come ,go ,leave ,return ,open ,close 等短暂位移动词表规定计划。
The plane takes off at 11:30. (不受主观支配的计划)
-在剧本、解说、标题或there (here)开头的句中表进行
There goes the bell/Here comes Mr.Wang.
I declare the meeting opens.(正在宣布)
He meets the ball and hits back to No.2 (正在发生)
B.现在进行时
1.说话时正在发生,进行的动作
Look! Dark clouds are gathering1 . (正在发生)
2.表现阶段正在进行,但此刻不一定正在进行的事。
He usually gets up at 6:00 , but this week he is getting up at 7:00. (现阶段正在进行,但说话时不一定在起床)
3、现在进行时的特殊意义
-表示主观打算常用于 go , come , leave , start , begin 等,位移、趋向动词。
How long are you staying here ? (准备停留)
-表示眼前刚过去的语意即“话音刚落”,适用于tell , say , talk , discuss ….
You don’t believe it ? You know I’m telling the truth.
-表示安慰、关心、喜欢、讨厌……感情色彩。
He is always making noises in class. (讨厌)
-在条件、时间、让步状语从句中表示将来正在进行。
Don’t bother him if he is reading this time tomorrow.
二、严格区分进行时与一般时的语义。
a) 持续动词的一般时表持续情况,经常性,习惯性行为或客观存在的事实,进行时表暂时性或有限时刻的持续。
He lives in Beijing.(生活在北京-习惯性)
He is living in Beijing.(目前住在北京暂时性)
b) 短暂动词的一般时叙述事实,特征,能力而短暂动作进行时描述反复发生,即将发生或刚开始行为。
He jumps high. (特征)
He is jumping very high. (反复)
c) 短暂动词和静态动词一般时表示实际情况客观状态、结果、特征、特性,进行时表未完成含开始或渐进之意。
The bus stops. (车停了-事实)
The bus is stopping. (渐渐停下来)
I love the job. (静态事实)
I am loving the job. ( 渐渐爱上了)
d) come ,go ,leave ,start ,return ,move ,reach ,sail ,fall 等一般时态表客观规定计划,进行时表主观打算推测。
Flight 254 leaves at 5:30. (表主观打算)
The plane is taking off an hour later.(主观判断)
e) 现在进行时带always ,often ,usually ,sometimes ,等频率副词表感情色彩,一般现在时则没有此用法。
