動(dòng)詞ing的變化規(guī)則：
1．一般情況直接＋ing
例:sweep-sweeping read-reading
2．以不發(fā)音e結(jié)尾的去e＋ing
例：take-taking make-making have-having
ride-riding
3．重讀閉音節(jié)一個(gè)輔音字母結(jié)尾,雙寫輔音字母＋ing
例：shop-shopping sit-sitting swim-swimming,put-putting,begin-beginning
run-running ,cut-cutting 等
不用.教你一個(gè)雙寫的簡(jiǎn)單規(guī)則：最后三個(gè)字母是“輔音字母+元音字母+輔音字母”,并且重讀.
