as well 用法
用于什么句?（肯?一疑?还是全部?） 什么位置?与 TOO ALSO EITHER 区别?

as well；too;either;also的区别：　　1.also用于肯定句,既可表示两人干了同样的事,也可表示一个人干了两件事,通常位于be动词,助动词或情态动词之后,行为动词之前.如：　　He has been to Beijing.I have also been there.他去过北京,我也去过.　　He is good at English.He is also good at Japanese.他擅长英语,也擅长日语.　　I also wants some tea.我也要点茶.　　注意：表示强调时,also也可放在助动词或情态动词等之前.比较：　　I can also do it.我也能干.　　I also can do it.(同上)　 　　2.too也用于肯定句,比also更通俗,和also,as well可以相互替换,可放在句中,也可放在句末.如：　　Xiao Li went to Beijing and Xiao Zhao,too,went to Beijing.小李到北京去了,小赵也到北京去了.　　He studies hard and I study hard,too.他学习用功,我（学习）也用功.　　3.either用于否定句,而且只能放在句末.如：　　He didn’t know it.I didn’t know it either.他不知道那件事,我也不知道.　　I can’t speak French and can’t write it,either.我不会讲法语,也不会写法语.　　4.as well在口语中用得很多,用法和too完全一样,可以互换,通常位于句末.[见as well,as well as条].如：　　She not only sings,she plays the piano as well.她不但会唱歌,而且会弹钢琴.　　I can do it as well.这事我也能做.　　5.在含有责备、抱怨或规劝之类的句子中,若句子本身是以否定的形式表达肯定的意义时用“too”,而不用“either”.这类句子一般可用should,had better,would rather等改成肯定的形式,只是语气稍有不同.如：　　Can’t you see I’ve got teeth,too?你难道看不出我也有牙齿吗?（=You should see I’ve got teeth,too.）　 　　6.在表示建议或邀请的句子中,若句子是否定的形式,肯定的意义,用“too”而不用“either”.这类句子在大都可以改成肯定的形式.如：　　Won’t you come,too?你也来吗?（=Will you please come,too?或=Please come too.）　 　　Wouldn’t you have a cup of coffee too?您也来杯咖啡好吗?（=Please have a cup of coffee too.）　 　　7.在反意疑问句中,若主体句是肯定式,否定式的追加问句不影响整句的肯定意义,那么,主体句中可用“too”,而不可用“either”.如：　　She went to see her last Sunday too,didn’t she?她上星期天也去看她了,（不）是吗?（=Did she go to see her last Sunday too?）　 　　8.在具有否定意义的否定句中,否定词前可用“too”而不用“either”.但这类句子更常用“not…ether”结构来表达.如：　　He did not come,and she too did not come.他没来,她也没有来.（=He did not come,and she did not come either.）　 　　I believed,too,that I had never listened so attentively.我觉得我从来没有这么用心地听讲过.　　9.too虽在否定词后,但否定词仅仅是否定某个词或片语,而不影响全句的肯定意义时,一般用“too”而不用“either”.如：　　No worries and a comfortable place to sleep in are important,too.　　无忧无虑,睡的地方舒适也非常重要
