1、一般情況下，直接在動詞后加-ing.
work ---- working
sleep ----- sleeping
study ----- studying
go ---- going
play ----- playing
know ----- knowing
walk------walking
eat------eating
beat-----beating
sing-----singing
2、動詞以不發(fā)音的-e結(jié)尾，要去-e加-ing.
take ----- taking
make ----- making
dance ----- dancing
write-----writing
arrive ----- arriving
come ----- coming
3、以重讀閉音節(jié)結(jié)尾，且詞尾只有一個輔音字母時，先雙寫這個輔音字母，再加-ing（重閉單輔先雙寫）.
cut ----- cutting
put ----- putting
begin ------ beginning
run------running
stop ----stopping，
prefer---preferring
4、以-ie結(jié)尾，先將-ie改成y，再加-ing.
口訣：現(xiàn)在進行ing,以e 結(jié)尾要去e，除去幾個特殊詞，系住tie-tying死去die-dying要躺下lie-lying，直接ie變成y.
lie ----- lying
tie ----- tying
die ----- dying
