中考网整理了关于2021年初中英语语法之时态问题,希望对同学们有所帮助,仅供参考。
1、一般现在时
主要用来表示人、事物的现在状况和特点;表示经常或习惯性的动作,句子中常有often, always, from time to time 等;
表示客观规律和永恒真理等。
He usually goes to work at 7 o’clock every morning.
She has a brother who lives in New York.
The earth goes around the sun.
Guangzhou is situated in the south of China.
考点一:表示永恒的真理,即使出现在过去的语境中,仍用一般现在时。如:
I learned that the earth goes around the sun when I was in primary
school.
考点二:在时间和中,代替一般将来时;常用的引导词有:
时间:when, until, after, before, as soon as, once, the moment/the minute, the
day; 条件:if, unless, provided.
If he accepts the job, he will get more money soon.
考点三:在make sure (certain), see to it, mind, care, matter +宾语从句,
从句用一般现在时代替一般将来时。
So long as he works hard, I don’t mind when he finishes the experiment.
只要他努力工作, 我不介意他什么时候做完试验。
考点四:在the more… the more … (越……越……) 句型中, 若主句是一般将来时, 从句通常用一般现在时。
The harder you study, the better results you will get.
2、现在进行时
表说话时或目前一段时间内正在进行的活动:或表感情色彩,加强语气。与,如always,constantly,continually,again等连用表示说话人的某种感情色彩(赞叹、厌烦、埋怨等)。
We are having English class.
The house is being built these days.
The little boy is always making trouble.
考点一:在或中表示将来正在进行的动作。
Look out when you are crossing the street.
Don't wake him up if he is still sleeping at 7 tomorrow morning.
考点二: 表示在最近按计划或安排要进行的动作(这时多有表示将来的)。
Marry is leaving on Friday.
3、现在完成时
表示动作发生在过去,完成在过去,但强调与现在情况仍有联系,其结果或影响仍存在。现在完成时有一些标志性的时间状语:
考点一:for + 时间段;since + 时间点
They have lived in Beijing for five years.
They have lived in Beijing since 1995.
I have learned English for ten years.
考点二:常见的不确定的时间状语:lately; recently, just, already, yet, up to now; till now;
