Not only do I feel good about helping other people, but I get to spend time doing what I love to do. 我不仅对帮助别人感到很满足，而且我还渐渐地花时间做自己喜欢做的事情。(1)not only . but also (also可省略)是“不但而且”的意思，当置于句首时，not only后面从句的主谓要倒装，

11、但but （also）后面的主谓不用倒装。e.g.: Not only has he been to Canada, but (also) he knows some Canadians. 他不仅去过加拿大，而且还认识许多加拿大人。e.g.: Not only did he teach at school, but (also) he wrote novels. 他不仅在学校里教书，而且还写小说。6.

13、或复数名词前要用介词of连接，如each of them, each of the boys; every不能直接跟of连接，e.g.: 不可以说every of them，而要说every one of them或each of them。 every还可以表示“每隔”，后接基数词加名词，如every four weeks, every three months等，此种结构中的every不能用each代替。 e.g.: She had a rest every five minutes. 她每隔5分钟就休息一会儿。7. “Dont put it off,” says HuiPing.“Bec

16、其区别是： (a) get用于日常用语，后面常跟比较级。 e.g.: The weather gets colder, and the days get shorter. 天气变冷了，白天变短了。 (b) turn指在颜色和性质等方面变得与原来不同。 e.g.: His face turned red. 他的脸变红了。 (c) grow着重变化过程。 e.g.: Its growing dark. 天渐渐地变黑了。 (d) become是指身份、职位的变化，作瞬间动词时，指状态的变化。 e.g.: He became an artist. 他成为了一名艺术家。8.

18、用完”，其主语通常是人，表示主动含义，后面跟宾语。He has run out of ink.他用完了墨水。Im afraid wee run out of petrol.我们的汽油怕是已用完了。特别提示run out也是“用完”的意思，其主语通常是被使用的事物，如时间、金钱、食物等，但不用于被动语态，同时其后也不能跟宾语。His money soon ran out. 他的钱很快就花完了。Have you nearly finished? Time is running out. 你快做完了吗？时间快到了。10. Mario Green and Mary Brown from Riversi
