either的用法總結
以下是小編為大家總結了either 的用法 ，希望能幫助大家更好地掌握either這個單詞，提高英語水平。
第一步 區別副詞either, too, also
回憶這三個詞的用法，完成下列句子。
1. You haven’t seen him. I haven’t seen him, ___________.
2. I have seen the film before ,______________.
3. Are those cows black and white , __________?
4. She can ________ jump as high as 2 metres.
5. Neither of the students knows the answer, _________.
注意：含有too 結尾的句子變否定句時要改too 為either.如：
I have seen the movie and my brother has, too. (改為否定句)
I _______ seen the movie and my brother _______, _______.
第二步 區別不定代詞 either, neither, both, all, each, none
首先，明確這些不定代詞的詞義及相互之間的關系。
either “兩者中任意一個”, 單數，肯定;
each “每個，各個，各自”強調個體，單數 肯定;
both “兩者都”， 肯定，復數; neither“兩者都不”，否定，單數;
all “三個或三個以上都” 肯定，復數; none “三個或三個以上都不” 否定，單數
將下列句子變為否定句?
1. Both of the twins like football. Neither of the twins likes football.
2. All of the students have been to the park. None of the students has been to the park.
引導學生觀察句子的變化，并小結方法: 找準否定詞――注意主謂一致――保持時態一致
然后，概括這些不定代詞在句子中的共同用法：
①可單獨使用，在句子中當主語、賓語、或同位語。如：I like both . Either is OK.Neither is OK. Nothing is good for all. They each have a book.
②這些不定代詞都可可以當形容詞，修飾名詞。如：Both guests have arrived. 兩個客人都已到了。Both her fingers are broken. 她的兩個手指都斷了. All the windows are open.所有的窗子都開著。
③這些不定代詞都可后接of + 名詞/代詞賓格的復數形式。如：Neither of the books is mine. Both of the boys are looking at the pictures. None of the doctors can save the girl. Either of them is right (兩者中一個是對的). Neither o f them is right(兩者都是不對) .Each of us is right.All of us are here.
接著，學會判斷這些不定代詞在句子中的運用

怎么區別Which of,Either of,neither of,both of,each of ,none of,all of ?
which of 解釋為“……中的哪個”用于特殊疑問句開頭
例句：Which of the sentences if true ?哪個句子是對的?
either of 解釋為“兩個中的任意一個”
例句：Either of the two sentences is true. 這兩句句子中的一句是正確的
neither of 解釋為“兩者都不”
例句：Neither of the sentences is true. 這兩句句子都不對
both of 解釋為“兩者都”
例句：Both of the sentences are true. 這兩句句子都對
Each of 解釋為“每一個都”強調具體的個體，不是強調整體
Each of us is right, 我們每一個人都是正確的。
None of 解釋為“三者都不”接不可數，謂語用單數，接可數則謂語單復數均可與all of "兩者都”謂語均用復數，這兩個剛好是對反義詞
None of us is / are right. All of us are right
So do I . / Neither do I 倒裝句的使用
