1. 肯定簡應句中，用 so 或 too 來表「也」。so 是副詞，表示「同樣地」，故之前要有連接詞 and 連接兩句，而且 so 之後須採倒裝句構；too 亦為副詞，置於句尾使用，簡應句不須倒裝，且其前多置逗點，句型如下：
肯定句, and so + be 動詞／助動詞 + S
= 肯定句, and + S + be 動詞／助動詞, too
a. be 動詞：主詞與 be 動詞倒裝
Larry is nice, and so is his sister.（賴瑞人很好，他妹妹也是。）
= Larry is nice, and his sister is, too.
Amy was going home, and so was Kelly.（艾咪要回家了，凱莉也是。）
= Amy was going home, and Kelly was, too.
b. 助動詞：主詞與助動詞倒裝
He will come to the party, and so will she.（他會來參加派對，她也會。）
= He will come to the party, and she will, too.
He has finished his homework, and so has she.（他已經做完功課，她也做完了。）
= He has finished his homework, and she has, too.
c. 一般動詞：主詞與 do、does、did 倒裝
He came, and so did she.（他來了，她也來了。）
= He came, and she did, too.
He has a sense of humor, and so does she.（他有幽默感，她也有。）
= He has a sense of humor, and she does, too.
2. 否定簡應句中用 neither、nor 或 either 來表「也不」。neither 為副詞，表「也不」，故其前須置and 連接兩個否定的主要子句，而 nor 為連接詞，亦表「也不」，其前不必置 and，且使用 neither或 nor 之後必須接倒裝句；either 則置於句尾使用，其前要有否定副詞，再置逗點，且不採倒裝句構，句型如下：
否定句, and neither + be 動詞／助動詞 + S
= 否定句, nor + be 動詞／助動詞 + S
= 否定句, and + S + 否定 be 動詞／助動詞, either
a. be 動詞：主詞與 be 動詞倒裝
He isn’t nice, and neither is she.（他不好，她也不好。）
= He isn’t nice, nor is she.
= He isn’t nice, and she isn’t, either.
He wasn’t feeling well, and neither was she.（他不太舒服，她也不太舒服。）
= He wasn’t feeling well, nor was she.
= He wasn’t feeling well, and she wasn’t, either.
b. 助動詞：主詞與助動詞倒裝
He won’t come, and neither will she.（他不會來，她也不會。）
= He won’t come, nor will she.
= He won’t come, and she won’t, either.
He hasn’t come back yet, and neither has she.（他還沒有回來，她也還沒。）
= He hasn’t come back yet, nor has she.
= He hasn’t come back yet, and she hasn’t, either.
c. 一般動詞：主詞與 do、does、did 倒裝
He never tells a lie, and neither does she.（他從不說謊，她也從不說謊。）
= He never tells a lie, nor does she.
= He never tells a lie, and she doesn’t, either.
He has no money, and neither does she.（他沒有錢，她也沒有。）
= He has no money, nor does she.
= He has no money, and she doesn’t, either.
注意
有些字典及文法書會將 nor 視為副詞，前面用 and 來連接兩個子句，或是將 neither 視為連接詞，直接用 neither 來連接兩個子句，而不用 and。
3. 在對話中，兩句指的是同一人時，不論句子是肯定句或否定句，均用 so 引導，且句子不倒裝。此時so 亦為副詞，相當於 indeed（的確）。
A: He is stupid.（甲：他很蠢。）
B: So he is.（乙：他的確很蠢。）
= Indeed he is.
A: You can’t do it.（甲：你不會做這事。）
B: So I can’t. （乙：我的確不會。）
= Indeed I can’t.
4. also（也）只能用在肯定句中，置於 be 動詞或助動詞之後或一般動詞之前。
He is kind, and she is also kind.（他很親切，她也是。）
He has a pen, and she also has one.（他有一支筆，她也有一支。）
He can swim, and she can also swim.（他會游泳，她也會游泳。）
