高中英语现在进行时的语法知识点
1. 现在进行时的定义
现在进行时主要用于表示目前正在进行的动作，有时也可表示现阶段在进行的动作。如：

The farmers are getting in their crops. 农民们正在收割庄稼。
We are making preparations for the conference. 我们一直在为会议作准备。
2. 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.
3. 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。
4. 现在进行时与一般现在时的区别
(1) 现在进行时强调目前正在进行的动作，而一般现在时强调经常性或习惯性的动作。如：
I’m reading a story now. 我在看一个故事。(目前正在干的事情)
I read stories in my spare time. 我有空时看故事。(经常性的行为)
(2) 现在进行时强调现阶段一直在进行的动作，而一般现在时只表动作的重复，而不表示动作的持续。如：
What are you doing these days? 这几天你在干什么?
They are learning English in the summer holiday. 他们暑假在学英语。
They read English every day. 他们每天读英语。
They play volleyball every Sunday. 他们每周星期天都打排球。
(3) 表示短促动作的动词(如 jump, knock, beat, pick, skip等)的进行时，表示动作的重复。如：
The girls are jumping over there. 女孩子们在那边跳。
His heart is beating fast. 他的心脏跳得很快。
(5) 某些表示希望或想法的动词(如hope, wonder, want等)的进行时可以表示委婉客气。如：
I’m wondering whether you can help us now. 我不知道你现在能否给我们帮一忙。
I’m hoping that you will succeed. 我正在希望你成功呢。
高中英语现在完成进行时的语法知识点
1. 现在完成进行时的定义
现在完成进行时表示某动作从过去某个时间开始，一直延续到现在，并且还有可能持续下去。如：
We have been waiting for him for two hours. 我们等他等了两个小时。
2. 现在完成进行时的结构
现在完成进行时由“have /has been + 现在分词”构成。
3. 现在完成进行时的应用
现在完成进行时所用的时间状语：this month / week / year, these days, recently / lately, in the past few + 时间段, since +时间点, for + 时间段。如：
They have been building the bridge for two month. 两个月来他们一直在修桥。
They have been planting trees this month. 这个月来他们一直在植树。
4. 现在完成进行时与现在完成时的区别
(1) 现在完成时强调动作的完成，而现在完成进行时强调动作的延续，因此，表示动作的完成，只能用现在完成时，而不能用现在完成进行时。如：
He has changed his idea. 他改变了想法。
(2) 在表示动作的延续时，虽然既可用现在完成时，也可用现在完成进行时，但现在完成进行时强调动作的进行。因此在需要明确表示动作还要持续下去时，应用现在完成进行时。如：
We have been studying here for two years. 我们在这儿已经学习了两年了。
(3) 有些延续性动词(如 keep, learn, live, stay, study, work等)，用于现在完成时或现在完成进行时的区别不大。如：
I have lived here for many years.=I have been living here for many years. 我在这儿住了多年了。
