现在进行时 知识点

一、现在进行时的概念:现在进行时表示现在进行的动作或存在的状态。现在进行时表示动作发生的时间是“现在”,动作目前的状态是“正在进行中”。  
二、现在分词的变化规则:
情况 变化 原形→现在分词
一般动词 加+ing wash→washing
read→reading
以不发音字母e结尾的动词 去掉e,再加+ing make→making
use→using
以重读闭音节结尾的动词且末尾只有一个辅音字母(字母w、y、x除外) 双写最后的辅音字母,再加+ing run→running
swim→swimming
以ie结尾的动词 变ie为y,再加+ing die→dying
tie→tying
以c结尾的动词 变c为ck,再加+ing picnic→picnicking
traffic→trafficking(例外:arc作弧形运动,arcing)
以l结尾的动词 如果动词原形以非重读音节结尾,则末尾的字母l双写与不双写均可。其中不双写的是美式拼写。 travel→travelling/traveling(U.S.)
部分以-p结尾的动词同样遵循第6条,这类词多由“前缀+名词”构成。 如果动词原形以非重读音节结尾,则末尾的字母p双写与不双写均可。其中不双写的是美式拼写。 worship→worshipping/worshiping(U.S.)
handicap→handicapping/handicaping(U.S.)
三、现在进行时的构成:主语+be动词(am /is /are)+动词ing形式〔现在分词〕
1. 肯定句:主语+be动词(am /is /are)+动词ing+其他。
2. 否定句:主语+be动词(am /is /are)+not+动词ing+其他。
3. 一般疑问句:be动词+主语+动词ing+其他。
肯定回答:Yes,主语+ be.
否定回答:No,主语+ be not.
4. 特殊疑问句:特殊疑问词+一般疑问句
四、现在进行时的用法:
1、当句中出现的表示时间的词是now,at the moment等时,表示句子要说明的是现在正在发生的事,动词应用现在进行时。例如:Linda's brother is watching TV in his bedroom now.
现在,琳达的哥哥正在他的卧室里看电视。
2、当句中出现的时间状语是these days,this week,this month,this term 等时,如果句子所要表达的意义是在这一阶段正在发生的事,则动词应用现在进行时。例如:These days we are helping the farmers work on the farm.这些天我们在农场帮农民们干活。
3、在句中出现了Look,Listen,Can't you see? 等暗示词时,说明后面谓语动词的动作正在发生,该动词应用现在进行时。
例如:Look! Maria and Tom are dancing under the tree.看!玛丽亚和汤姆正在树下跳舞。
4、注意根据上下文的暗示,句子的谓语动词可能应用现在进行时。
例如:— Where is Mr Wang?—王先生在哪儿?— Oh, he is reading a newspaper in the office.— 噢,他正在办公室看报。
(问句询问王先生在哪儿,应说明他现在在哪儿,故答句应说明他现在正在做的事,用现在进行时。)
5、现在进行时态表将来,主要用于表示按计划或安排要发生的动作。常有“意图”“决定”的意思。例如:They're getting married next month.他们下个月结婚。
注意:
1、在英语中,并不是所有的动词都要使用正在进行时。一些表示状态和感觉的动词,一般不用进行时态,而是用一般现在时表示。例如“I hear someone singing.我正听见有人唱歌。
如果这些词使用正在进行时态,句子带有某种感情色彩。例如:Are you seeing someone off?你在给谁送行吗?
2、现在进行时还有另外一种含义,即它们能表达即将发生的事情,相当于一般将来时。能够用来表示将来状况的动词有:arrive,come,do,get,go,have,leave,meet,play,return,see,spend,start,stay,wear,work 等。例如:A foreign guest is giving a lecture this afternoon。今天下午一个外国客人将给我们作报告。
3、当其与always,forever,continually,constantly 等副词连用时表示重复的动作,有着极大的感情色彩,表示不满或满意。例如:She is perpetually interfering in my affairs.她老是干预我的事。 (不满)
