現(xiàn)在分詞的變化規(guī)則1. 一般情況下，在動詞后加-ing構(gòu)成： workworking 工作 sleepsleeping 睡 waitwaiting等待 studystudying 學(xué)習(xí) readreading 讀 talktalking 談話 2. 不發(fā)音的-e結(jié)尾的動詞去掉e后再加-ing： smilesmiling 微笑 movemoving writewriting 寫 come-coming leave -leaving take -taking bite -biting have having wake-waking make-making dance-dancing ride-riding但是，若是發(fā)音的e結(jié)尾，則不能去e： seeseeing 看見 agreeagreeing 同意 3. 以重讀閉音節(jié)或r音節(jié)結(jié)尾且末尾只有一個輔音字母動詞，要雙寫末尾的輔音字母再加-ing： sitsitting planplanning preferpreferring run -running swim -swimming shop -shopping begin -beginning stop-stoppingforget-forgetting cut-cutting get-getting hithitting set-setting fit-fitting digdigging重讀閉音節(jié)是指：這個動詞是重讀音節(jié)，同時單詞的最后也是以輔音字母結(jié)尾的閉音節(jié)。音節(jié)：1.單音節(jié)：音標(biāo)中含有一個元音；（單音節(jié)全是省略了重讀符號的重音節(jié)）2.雙音節(jié)：音標(biāo)中含有二個元音；（會有重讀符號標(biāo)在某個需重讀的音節(jié)前）3.多音節(jié)：音標(biāo)中含有三個或三個以上的元音音標(biāo)。（會有重讀符號標(biāo)在某個需重讀的音節(jié)前）音節(jié)：1開音節(jié)1）以發(fā)音的元音字母結(jié)尾的單節(jié)。例：be，he。2）以輔音字母（r除外）+不發(fā)音的e結(jié)尾的音節(jié)。例：make，like。*在重讀的開音節(jié)中元音字母按字母名稱讀音。2閉音節(jié)以一個或幾個輔音字母（r除外）結(jié)尾而中間只有一個元音字母的音節(jié)，稱為閉音節(jié)。例：map，desk，is。*在重讀的閉音節(jié)中元音字母讀做短元音。重讀閉音節(jié)要判斷一個單詞是否是重讀閉音節(jié)，必須同時滿足下列三個條件：、這個音節(jié)必須重讀；、這個單詞結(jié)尾必須是“輔元輔”，即“輔音字母元音字母輔音字母”；、在這個“輔元輔”中的元音字母必須發(fā)短音。只有這三個條件同時成立的情況下，這個單詞才能算是重讀閉音節(jié)。如：put,dig 思考：listen play4. 以字母ie結(jié)尾的動詞，通常將ie改為y，再加ing： diedying 死 lielying 躺 tie-tying 系住【注】 以字母l結(jié)尾動詞，若末尾一個音節(jié)為重讀音節(jié)，則必須雙寫l再加ing，如control / controlling，但若末尾一個音節(jié)為非重讀音節(jié)，則可雙寫l(英國英語)或不雙寫l(美國英語)，如travel / travel(l)ing。現(xiàn)在進(jìn)行時的結(jié)構(gòu)句式 結(jié)構(gòu)肯定句 主語+ am / is / are +動詞-ing形式+其他.否定句 主語+ am / is / are + not +動詞-ing形式+其他.一般疑問句 Am / Is / Are +主語+動詞-ing形式+其他?肯定回答 Yes, 主語+ am / is / are.否定回答 No, 主語+ am / is / are + not.特殊疑問句 疑問詞+ am / is / are +主語+動詞-ing形式+其他?考試中?？嫉默F(xiàn)在進(jìn)行時的應(yīng)用 (1)當(dāng)句子中有now時，常表示動作正在進(jìn)行，這時要用現(xiàn)在進(jìn)行時。如： They are playing basketball now.現(xiàn)在他們正在打球。(2)以look, listen開頭的句子，提示我們動作正進(jìn)行，這時要用現(xiàn)在進(jìn)行時。如： Listen！She is singing an English song.聽，她正在唱英語歌。 (3)表示當(dāng)前一段時間或現(xiàn)階段正在進(jìn)行的動作，且此時有this week, these days等時間狀語，這時常用現(xiàn)在進(jìn)行時。如： We are making model planes these days.這些天我們在做飛機(jī)模型。 (4)描述圖片中的人物的動作，也為了表達(dá)更生動。此時也常用現(xiàn)在進(jìn)行時。如： Look at the picture.
