also, too, as well, either的区别、用法及练习题also, too, as well, either中文都有“也”的意思also, too, as well都只用在肯定句之中，只是在句中所用的位置不同而either只用在否定句之中下面是结合例句的详细讲解1. also, 用于肯定句中，表示“也”的意思如：— Jane speaks French. Sam also speaks French.— He loves chocolate. I also love pizza.— Frank can come with us. Nancy can also come with us.also在句子中的位置，主要有四种情况：(1) 放在be动词之后如：— I am also Canadian.— I was also there.(2) 放在实义(行为)动词之前如：— I also sing.— He also helped us.(3) 放在助动词、情态动词之后如：— I have also been to Hong Kong.— I am also studying economics.— I can also speak French.— I should also be there.(4) 放在句首，用逗号隔开，表示强调。

如：— It’s very humid. Also, you can easily get sunburnt.— It is a small house. Also, it needs a lot of repairs.2. too, 用于肯定句中，表示“也”的意思如：— Jane speaks French. Sam speaks French too.— I love chocolate. I love pizza too.— Frank can come with us. Nancy can come with us too.too, 在句子中的位置，主要有两种情况如：(1) 放在句子末尾，可以用逗号隔开，也可以不用逗号隔开如：— David is a teacher. His wife is a teacher, too. (用逗号隔开)— David is a teacher. His wife is a teacher too. (不用逗号隔开)— I can speak French too.— I am studying economics too.— If he wants to go too, he should meet us at 8:00.(2) 插入句子中。

作为正式用语，too也会插入句子中间，但必须紧跟主语之后作为插入语，通常用逗号隔开，但不能用在助动词或情态动词之后如：— We, too, have been very pleased to receive the prize on her behalf.— I too thought she looked unwell.— I, too, have been in such situations. （必须紧跟主语）— We have too been very pleased …（错误用法，不能放在助动词之后）另外，too也用于固定搭配，多用于口语如：— A: Enjoy the play. B: Thanks. You enjoy your evening too.通常不说：You enjoy your evening as well.或You also enjoy your evening.— A: I need to go to the gym. B: Yeah, me too.— A: I am going home. B: Me too. (= So am I. / I am as well. I am also going home.)— A: I like this song. B: Me too. / I like it too. (= So do I. / I do as well. I also like it.)— A: I graduated from the University of British Columbia.B: Really? Me too! / I did too! (= So did I. / I did as well. I also did.) 通常不说：I too. (较正式) 或 me also.(无此用法) 或 me as well. (无此用法)3. as well, 用于肯定句中，表示“也”的意思。

用法与too基本相同，放在句子末尾比较下面三句话，比较to, as well, also在句子中的位置— Paul is an artist. He paints, and he carves wood too.— Paul paints and he carves wood as well. — Paul paints and he also carves wood!比较：— I just ignored it. I think everybody else did as well.— Not: As well I think everybody else did.（错误用法，不能把as well放于句首）另外，as well, 多用于口语祈使句中”和“简短答语中”通常使用too和as well, 而不使用also. 如：— Give me a book of ten first and a book of ten second as well then please.4. either, 表示“也”的意思时，只用于否定句中，且只放在句子末尾，可以加逗号，也可以不加逗号如：— Jane doesnt speak French. Sam doesnt speak French either.— I dont love chocolate. I dont love pizza either.— Frank cannot come with us. Nancy cannot come with us either.— I cannot speak French either.— I am not studying economics either.— I dont want to eat either.— I didnt like the movie either.比较：— Bill’s not here. I don’t think Dave is either, is he?— Not: I don’t think Dave is also/as well/too. (错误用法，also, as well ,too不用于否定句）5. 综合比较。

总体来说，also, as well, too均有“也”的意思，但在英文句子中使用的位置不同，请再次仔细体会下面几组句子，仔细辨析also, as well, too在句子中的位置— He not only plays; he also works.— He not only plays; he works as well.— He not only plays; he works too.— He was fat, and he was also short.— He was fat, he was short as well.— He was fat, he was short too.— I also like chocolate.— I like chocolate also.
