also,too这两个词都是副词,又都表示“也是”的意思,但在修辞意味和使用场合上有所不同.它们的区别如下:(一)一般说来,also用于比较正式(formal)的场合,语气比too庄重; too是惯熟(familiar)的用语,使用范围较广.(二)also在句中的位置要紧靠动词; too在句中的位置比较灵活,有时插入句中,前后用逗号分开,有时放在句末.(三)too只能用在肯定句中,不可用于否定句内.在否定句中,只能用either;also则可以用在否定句中.下面请看例句:The Hong Kong Chief Executive also heads the university as Chancellor.香港行政长官也以(大学)校监身份领导大学.Reading books is learning,but application is also learning and the more important form of learning.读书是学习,买践也是学习,而且是更重要的学习.We have not heard such a thing.Also,we have never seen such a scene.我们没有听见过这种事情,我们也从来没有见过这种场面.请注意,一般说来,also在句中的位置应紧靠动词,但有时为了强调其意,也可以将它放在句首或句末.Here,too,the colon must be followed by a dash.这里也一样,应当在冒号之后加破折号.Mary,too,can play the piano.玛丽也会弹钢琴.Could you speak Japanese?—Yes,and Spanish too.您会说日语吗?——会的,还会说西班牙语哩.Also虽然和too同义,但前者大都用于书面语,后者大都用于口语.例:The lady washed the children and also gave them dinner.(书面语)The lady washed the children and gave them dinner too.(口语)
