   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 teacher is giving us an English lesson. 老师正在给我们上英语课。
  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 1 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 2 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。
  (4) 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。
