一、  現(xiàn)在進(jìn)行時(shí)的概念：現(xiàn)在進(jìn)行時(shí)態(tài)表示1. 現(xiàn)在（說(shuō)話瞬間）正在進(jìn)行或發(fā)生的動(dòng)作。  2. 現(xiàn)階段一直在進(jìn)行的動(dòng)作。二、  現(xiàn)在進(jìn)行時(shí)的結(jié)構(gòu)：主語(yǔ)+be（am , is , are）+現(xiàn)在分詞（動(dòng)詞+ing形式）+其它肯定句式：主語(yǔ)+be( am, is, are)+現(xiàn)在分詞+其它.否定句式：主語(yǔ)+be(am, is, are) +not +現(xiàn)在分詞+其它.一般疑問(wèn)句：Be(am, is, are) +主語(yǔ)+現(xiàn)在分詞+其它  三、  現(xiàn)在分詞的構(gòu)成規(guī)則：動(dòng)詞+ing形式叫做動(dòng)詞的現(xiàn)在分詞，現(xiàn)在分詞的構(gòu)成方法如下：1. 一般在動(dòng)詞后直接加上-ing。例如：workworking, dodoing, talktalking,drinkdrinking2. 以不發(fā)音e結(jié)尾的動(dòng)詞應(yīng)先去掉e然后加-ing。例如：writewriting, skateskating3. 以ie結(jié)尾的動(dòng)詞，變ie為y加-ing。例如：lielying, diedying4. 單詞末尾的字母結(jié)構(gòu)是“元音字母+輔音字母”。例如： runrunning, beginbeginning  plan planning, swim swimming, sit sitting, get getting, put putting, shop shopping, ski skiing四、  現(xiàn)在進(jìn)行時(shí)的句型變化They are reading an English book.（肯定句）They are not reading an English book.（否定句）Are they reading an English book? （一般疑問(wèn)句）提問(wèn)： _ 五、  現(xiàn)在進(jìn)行時(shí)的時(shí)間狀語(yǔ)1.表示時(shí)間的詞是now, at the moment/at present (此刻、現(xiàn)在,) Its + 具體點(diǎn)鐘等時(shí)，表示句子要說(shuō)明的是現(xiàn)在正在發(fā)生的事Linda's brother _ (看電視) in his bedroom now.We're far from home. _ at the moment?我們的父母此刻在干什么呢？Its seven oclock p.m.  My mum _?(在做飯)2. 當(dāng)句中出現(xiàn)的時(shí)間狀語(yǔ)是these days, this week, this month等時(shí)，如果句子所要表達(dá)的意義是在這一階段正在發(fā)生的事These days we _ on the farm. 這些天我們?cè)谵r(nóng)場(chǎng)幫農(nóng)民們干活。They _ this week. 這一周他們?cè)谶M(jìn)行一次考試。Mr Cheng _ our village this month. 這個(gè)月程先生在我們村訪問(wèn)。 3. 在句中出現(xiàn)了Look, Listen, Can't you see? 等暗示詞時(shí)，說(shuō)明后面謂語(yǔ)動(dòng)詞的動(dòng)作正在發(fā)生Look!

No. Jack _(do) his homework in the classroom.  六、  現(xiàn)在進(jìn)行時(shí)的特殊情況1  有些動(dòng)詞從結(jié)構(gòu)來(lái)看是現(xiàn)在進(jìn)行時(shí)，但卻是表示將要發(fā)生的事，而不表示動(dòng)作現(xiàn)在正在進(jìn)行。這些動(dòng)詞往往是一些表示位置移動(dòng)變化的動(dòng)詞，如：go , come , leave , fly , move, start, begin , arrive, , stay, return等。Next month my family is moving to Beijing. _My aunt is leaving for Shanghai at eleven o'clock tomorrow morning. _ 圣誕節(jié)快到了。 _2  并不是所有動(dòng)詞都有進(jìn)行時(shí)，一些動(dòng)詞一般在句中不能用現(xiàn)在進(jìn)行時(shí)態(tài)，而應(yīng)用一般現(xiàn)在時(shí)。這些動(dòng)詞往往是等表示情感狀態(tài)、知覺(jué)認(rèn)識(shí)、愿望或短暫性的動(dòng)詞。例如：see（明白） , know, want , like , hear , have(擁有) , think , hope , hate等Look! Sandy _ (have) a new music box now.Look! They _ (have) an English class now.
