also 1.属正式用词,主要用于肯定句或疑问句,一般不用于否定句 (否定句可用 either),它在句中通常放在实义动词之前,特殊动词 (动词be、情态动词、助动词)之后,有时也放在整个谓语前面或放在句首或句尾 (较少见,且多半是因为强调之故).
如：I’ve also read the book.我也读过这本书.
This room was also dirty.This room alsowas dirty.This room was dirty also.
Also this room was dirty.这个房间也很脏.
2.有时由于also 位置不同,可能会导致句子含义不同.
如：We also regard him as a great writer today.我们也 (同别人一样)把他看成当今伟大的作家.
We regard also him as a great writertoday.我们把他也看成当今伟大的作家.
We regard him as a great writer also today.我们仍 (同其它时候一样)把他看成当今伟大的作家.
3.在简略答语中,习惯上不用also,如一般不说 I also,但可说Me too,You too等之类的.
如：A：I’m tired.我累了.B：Me too.我也是.
B：I also.(误)
