So do I 与 Neither do I
「我也是 / 我也不」的倒装句,注意和「确实如此」区分。
So + 助动词 + 主语(也一样);Neither / Nor + 助动词 + 主语(也不)
要点
  1. 前面是肯定句,表示「……也一样」用 So + 助动词 + 主语:I like English. — So do I.
  2. 前面是否定句,表示「……也不」用 Neither / Nor + 助动词 + 主语:I don't like rain. — Neither do I.
  3. 助动词、情态动词、be 动词要与前面句子保持一致:He can swim. — So can I. / She is a nurse. — So is my sister.
  4. 前句既含肯定又含否定(不同主语)时分开说:I like coffee but I don't like tea. — So do I, and neither does he.
  5. 「确实如此」不倒装:So + 主语 + 助动词 —— He works hard. — So he does.(他的确努力)
  6. 前句带 never / hardly / seldom 这类"看着是肯定、其实含否定"的词,答"也不"仍要用 Neither:He never drinks tea. — Neither do I.
  7. 前句是复合时态时,只搬头一个助动词过来:She has been waiting for an hour. — So has he. —— be 与分词都留在原地,不跟着挪。
例句
I have never been to Hainan. — Neither have I.
我从没去过海南。——我也没有。
She finished her homework on time. — So did her brother.
她按时完成了作业。——她弟弟也是。
It looks like rain. — So it does. Let's take an umbrella.
看来要下雨了。——确实。我们带把伞吧。
I can't stand the noise. — Neither can I. Let's close the window.
我受不了这噪音。——我也受不了。把窗关上吧。
You didn't lock the door. — Neither did I.
你没锁门。—— 我也没锁。
They have moved to another city, and so have we.
他们搬到别的城市去了,我们也是。
易错提示
  • 认准语序:So do I(倒装 = 也一样)vs So I do(不倒装 = 确实如此)。
  • 前句动词是过去时,回答用 did:I went to the library. — So did Tom.
  • 不想倒装就走陈述式加 not … either:I don't like rain. — I don't like it either. —— 一句里否定出现一次就够,别再叠一个 neither。
  • nor 也能顶在第二个分句前,后面照样倒装:He can't swim, nor can he skate. —— 它与 neither 在这一式里通用。
