這裡教您如何使用Neither、So、Either和Too。

Neither(也不) Vs. So(也是):

I don't like pineapple. Neither does she.
我不喜歡鳳梨。她也不喜歡。(前句是否定句與現在式, 後句用"Neither","She"是第三人稱單數, 前面要用"Does"。Neither does she. = She doesn't either.)
She is not in Taipei. Neither am I.
她不在台北。我也不在。(前句是否定句與Be動詞, 後句用"Neither","I"是第一人稱單數, 前面要用"Am"。Neither am I. = I am not either.)
We love baseball. So do they.
我們愛棒球。他們也愛。(前句是肯定句與現在式, 後句用"So", "They"是第三人稱複數, 前面要用"Do"。So do we. = We do too.)
My friends went to the party. So did I.
我朋友去了派對。我也去了。(前句是肯定句與過去式, 後句用"So",因是過去式, 不管第幾人稱單複數前面都用"Did"。So did I. = I did too.)

My parents will go to Japan. So will we.
我父母將要去日本。我們也會去。(前句是肯定句與未來式, 後句用"So",因是未來式, 不管第幾人稱單複數前面都用"Will"。So will we. = We will too.)

Neither除了"也不",也有"兩者皆不"的意思:

Neither Katie nor I wants to go to the party.
Katie和我皆不想去這派對。(第一人稱都是排後面,兩者皆單數, 動詞要用單數形態)
Neither my friends nor I want to go the party.
我朋友和我皆不想去這派對。(如一者單數一者複數, 動詞要用複數形態)
Neither the tourists nor the locals want to see the show.
觀光客和當地人皆不想看這表演。(兩者皆複數, 動詞要用複數形態)

Either(也不) Vs. Too(也是):

She can't go to the movie tonight. I can't either.
她晚上無法去看電影。我也不能。(前句是否定句, 後句句尾可用"Either", I can't either. = Neither can I.)
She isn't satisfied with the result. Me either.
她不滿意這結果。我也不滿意。(前句是否定句, 後句句尾可用"Either", Me either. = I am not either. = Neither am I.)

Tom loves ice cream. Me too.
Tom愛冰琪淋。我也愛。(前句是肯定句, 後句句尾可用"Too", Me too. = I do too. = So do I.)

Either除了"也不",也有"兩者任一"的意思:

Either Sandy or I is doing the housework.
Sandy和我其中一人會做家務。(第一人稱都是排後面,兩者皆單數, 動詞要用單數形態)
Either my roommates or I are doing the housework.
我室友們和我其中一方會做家務。(如一者單數一者複數, 動詞要用複數形態)
