  初中英语时态知识点:过去进行的结构

  过去进行时的结构及句型变化

  过去进行时由"was / were + 现在分词"构成。如:

  I was doing my lessons then. 那时,我在做功课。

  We were cleaning the house. 我们在打扫房子。

  过去将来时态的肯定句、否定句和疑问句形式:

  肯定句例句:I was walking down the street when a UFO landed.

  否定句例句:I wasn't walking down the street when a UFO landed.

  一般疑问句例句:Were you walking down the street when a UFO landed?

  特殊疑问句例句:What were you doing when a UFO landed?

  初中英语时态知识点:一般现在表过去的用法

  1.用于某些动词(tell, say, hear, learn, gather等)表示不确定的过去时间:

  John tells me you will leave tomorrow. 约翰告诉我你明天离开。

  I hear that he got married last month. 我听说他上个月结婚了。

  I hear you want a secretary. 我听说你需要一个秘书。

  He says the matter is rather urgent. 他说这事相当紧急。

  Mary says you told her to come over here. 玛丽说是你让她到这儿来的。

  It really gets me when he says those stupid things. 他说那些傻话真让我生气。

  2.当要陈述一个客观事实时,有时即使有过去时间状语也可用一般现在时:

  The story is set in the summer of 1937. 故事的背景是1937年夏天。

  The story begins in the year 1937. 故事开始于1937年。

  初中英语时态知识点:运用现在进行时常见的几个错误

  1、把动词变成现在分词形式易出错。例:

  (1)误:They are swiming (swim) .

  正:They are swimming (swim).

  (2)误:Jenny is plaiing (play) football.

  正:Jenny is playing (play) football.

  解析:A、动词变现在分词可有如下口诀:一般-ing;哑e先去e;重闭单辅先双写;-ie结尾y来替。

  B、动词现在分词的变化规则要与名词变复数、动词变现单三等规则区分开来。

  2、谓语部分的构成不完整:丢掉be动词,或忘记把动词变成现在分词。例:

  (1)误:Look! Two children flying (fly) a kite in the park.

  正:Look!Two children are flying (fly) a kite in the park.

  (2)误:Li Ming isn't read ( not read) a book in bed now.

  正:Li Ming isn't reading ( not read) a book in bed now.

  解析:现在进行时的谓语部分的构成是"be+现在分词",二者缺一不可,这一点必须要牢记。

  3、对动词或动词词组提问时,丢掉代动词doing。例:

  The students are singing in the room.(对划线部分提问)

  →误:What are the students in the room?

  →正:What are the students doing in the room?

  解析:现在进行时态中对动作提问可记住此句式"What +be +主语+doing+其它?"或简写为"What......doing......? "句式。

  4、现在进行时态的谓语部分是并列结构时,容易忽视第二个以及第二个以后的'动词用现在分词形式。例:

  孩子们在跑还是在跳?

  误:Are the children running or jump?

  正:Are the children running or jumping?

  解析: or连接的是两个并列成分,动词形式须一致。

  初中英语时态知识点:现在进行时的三种句式结构

  现在进行时在句式的变化上,都应在助动词be上做文章。

  1、 肯定式:be(am, is, are)+ Ving(现在分词) 如:

  They are having an English class. 他们在上英语课。

  2、 否定式:be(am, is, are) + not + Ving(现在分词) 如:

  They aren't having an English class. 他们不在上英语课。

  3、 疑问式:将be的具体形式(即am, is或are)提前到句首。如:

  Are they having an English class? 他们在上英语课吗?

  助动词变化口诀:变疑问,往前提,句后问号莫丢弃;变否定,更容易,be后not 莫忘记。

  初中英语时态知识点:现在进行时结构

  现在进行时的结构

  现在进行时由“am / is / are + 现在分词”构成。如:

  I’m studying at Yu Cai Senior Middle school. 我在育才中学读书。

  He is writing on the desk. 他再课桌上写字。

  They are talking about their visiting the Great Wall. 他们在谈论游长城的事情。

  【说明】动词现在分词的构成方法:

  (1) 一般在动词后加-ing。如:say—saying, play—playing, think—thinking, study—studying, teach —teaching, blow—blowing, build—building.

  (2) 动词若以-e结尾, 则去e再加-ing。如:love—loving, make—making, guide—guiding, date—dating.

  (3) 在以单短元音的重读闭音节结尾,且末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ing。如:begin—beginning, regret—regretting, plan—planning, ban — banning.

  (4) 在以ie结尾的动词后,改ie为y,再加-ing。如:lie—lying, die—dying, tie—tying.

  (5) 在以-c[k] 结尾的动词后加-king。如:picnic—picnicking, panic—panicking.

  初中英语时态知识点:现在进行时的应用

  现在进行时的应用

  (1) 表示目前正在发生或进行的动作。如:

  They are planting trees on the mountain. 他们在山上植树。

  Mother is preparing supper in the kitchen. 母亲在厨房做晚饭。

  (2) 有些非持续性动词的进行时可以表示动作即将进行或发生,或表示动作的重复。如:

  He is joining the army. 他要参军了。

  They are buying the house. 他们要买那座房子。

  (3) 当现在进行时中有always, forever, constantly, continually修饰时,表示说话人的赞赏或厌烦的感情。如:

  Why is the baby always crying? 为什么那个老是在哭。

  They are always helping us. 他们总是帮助我们。

  注意:表示状态、感觉、心理活动的静态动词,一般不使用语进行时态。
