1、現在分詞的變化規則1. 一般情況下，在動詞后加-ing構成： workworking 工作 sleepsleeping 睡 waitwaiting等待 studystudying 學習 readreading 讀 talktalking 談話 2. 不發音的-e結尾的動詞去掉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-ri

2、ding但是，若是發音的e結尾，則不能去e： seeseeing 看見 agreeagreeing 同意 3. 以重讀閉音節或r音節結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 digdiggin

3、g重讀閉音節是指：這個動詞是重讀音節，同時單詞的最后也是以輔音字母結尾的閉音節。音節：   1. 單音節：音標中含有一個元音；（單音節全是省略了重讀符號的重音節）   2. 雙音節：音標中含有二個元音；（會有重讀符號標在某個需重讀的音節前）   3. 多音節：音標中含有三個或三個以上的元音音標。（會有重讀符號標在某個需重讀的音節前）音節：1開音節 1）以發音的元音字母結尾的單節。 例：be，he。 2）以輔音字母（r 除外）+不發音的e

4、結尾的音節。 例：make，like。 * 在重讀的開音節中元音字母按字母名稱讀音。2閉音節 以一個或幾個輔音字母（r 除外）結尾而中間只有一個元音字母的音節，稱為閉音節。例：map，desk，is。 * *在重讀的閉音節中元音字母讀做短元音。重讀閉音節 要判斷一個單詞是否是重讀閉音節，必須同時滿足下列三個條件：、這個音節必須重讀；、這個單詞結尾必須是“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

5、節。如：put, dig  思考：listen play4. 以字母ie結尾的動詞，通常將ie改為y，再加ing： diedying 死 lielying 躺 tie-tying 系住【注】 以字母l結尾動詞，若末尾一個音節為重讀音節，則必須雙寫l再加ing，如control / controlling，但若末尾一個音節為非重讀音節，則可雙寫l(英國英語)或不雙寫l(美國英語)，如travel / travel(l)ing。現在進行時的結構句式 結構肯定句 主語+ am / is / are +動詞-ing形式+其他.否定句 主語+ am / is / are + not
