如come-coming , have-having , make-making,ride-riding,write-writing,take-taking,use-using．
如： hit-hitting,let-letting, put-putting,run-running,sit-sitting．
如: for’get-forgetting,pre’fer-preferring,up’set-upsetting．试对照 ’benefit/benfiting, ’differ/differing,’profit/profiting,这些词的重音在第一个音节上,是以其末真个辅音字母不双写．
5. 以 -ic 结尾的动词,应先把 -ic 变为 -ick,再加 -ing,eg: panic/panicking,picnic/picnicking,但 lie/lying ,die/dying,tie/tying是特殊变更要记着．
