not only … but also, as well as
注意：两者强调对象不同,not only … but also强调的是but also之后部分,而as well as则强调其前面的部分.not only … but also采取“就近原则”,而as well as只是一个插入语,采取“就远原则”.如：
Mr.Smith, as well as his wife and children, has come to Nanjing for a visit.
not only … but also结构中的not only可用于句首,连接两个分句时,第一个从句主谓要倒装.
Not only is he clever ,but also he is hard working.
