as well as 用于肯定句中,起连接作用=not only...but also 既......又......;不仅......而且...... He gave me clothes as well as food.他不仅给我衣服而且给我食物。 The child is lively as well as healthy.这个孩子既健康又活泼 He came as well as his brother.不仅他而且他哥哥也来了。 She as well as I IS a teacher.我是教师,她也是。 as well as 重在强调其前面的人或事物,连接并列主语时,谓语动词和前面的人或事物保持一致。 except 指在整体中除去一部分 We all succeeded except Tom.除了汤姆,我们都成功了。(成功的人中没有汤姆) besides 除...之外(还有...或外加...) We all succeeded besides Tom.除了汤姆成功外,我们也都成功了。(成功的人中包括汤姆) 也就是说,except表示的是“减法”,而besides表示的是“加法” 但是当besides用在否定句中时,意思等同于except。 I don't care for anything besides this.除了这个外,我不要别的了。
