(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)

(这句话应是在说话之前,我以为你病了。但是现在我知道你没病)
一变:肯定句变为否定句
技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.
二变:陈述句变为一般疑问句
技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如:
He could pack his things himself. → Could he pack his things himself?
技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如:
Mr Li looked very old. → Did Mr Li look very old?
三变:陈述句变为特殊疑问句
技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
They gave the concert last night. → When did they give the concert?
技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
The accident happened near the station. → Where did the accident happen?
考点名称:一般现在时
- 一般现在时:
:表示通常性、规律性、习惯性的状态或者动作(有时间规律发生的事件)的一种时间状态。 - 一般现在时的具体用法:
1. 表示经常的或习惯性的动作,常与表示频率的时间状语连用。
e.g. I leave home for school at 7:00 every morning.
2. 表示客观事实和普遍真理。
e.g. The earth moves around the sun.
3. 表示现在发生的具体动作或存在的状态
e.g. He lives in Beijing now.
4. 习惯性的爱好或行为
e.g. I like dancing while she likes singing.
5. 表示预先计划或安排好的行为。
e.g. Our class begins at 7:45.
6. 在时间状语从句和条件状语从句中,常用一般现在时代替将来时。
e.g. If you come, we will wait for you.
7. 表示格言或警句中。
e.g. Pride goes before a fall. 骄者必败。
8.表示主语具备的性格、能力、特征和状态。
e.g. I don't want so much.
Ann Wang writes good English but does not speak well.
比较:Now I put the sugar in the cup.

9.在时间状语从句和条件状语从句中,常用一般现在时代替将来时。
10.小说故事用一般现在时代替一般过去时。新闻报道类的内容,为了体现其“新鲜”性,也用一般现在时来表示过去发生的事情。
11.有些表示状态和感觉的动词表示现在发生的具体行为时,只用一般现在时,而不用进行时态。
注意★:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。
例:Columbus proved that the earth is round.. 第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me,I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。 - 一般现在时与现在进行时的区别:
一、两种时态的主要含义:
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 ___ in the east of China。 (lives) 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 等短暂谓语动词表规定计划。
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)
现在进行时
1.说话时正在发生,进行的动作
Look! Dark clouds are gathering . (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、讨厌等感情色彩。
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
1. 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。
2.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。
3.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)
4.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)
5.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。 一般现在时的句子转换:
(1)当句子中有be动词或情态动词时,则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句.
例:
①陈述句:She is a student.
疑问句→ Is she a student?
否定句→ She is not a student.
②陈述句:I can swim.
疑问句→ Can you swim
否定句→ I can not swim.
(2)当句子中即没有be动词,也没有情态动词时,则在主语前加助动词do (you,以及复数),does(单数she,he,it)变成问句;
在主语后谓语动词前加助动词don’t(I,you,以及复数), doesn’t(单数she,he,it)变成否定句,助动词后的动词要变成动词原形。
例:
①陈述句:We get up at 7:00 every morning.
疑问句→Do you get up at 7:00 every morning?
否定句→We don’t get up at 7:00 every morning.
②陈述句:She has a little brother.
疑问句→ Does she have a little brother?
否定句→ She doesn’t have a little brother.
