【摘要】：2013四级考试进入了最后的冲刺阶段，语法的知识点是难点和重点，以下是威廉希尔app 特为考生们整理了2013英语四级语法;涉及副词so的两类常考倒装，希望能给广大考生们在复习中作出一点贡献。预祝考生们通过考试!
这类倒装主要见于以下两种情形：
1. 当副词so后接形容词或副词位于句首时，其后要用部分倒装。如：
So cold was the weather that we had to stay at home. 天气太冷，我们只好呆在家里。
So fast does light travel that we can hardly imagine its speed. 光速很快，我们几乎没法想象它的速度。
So sudden was the attack that we had no time to escape. 袭击来得非常突然，我们来不及逃跑。
2. 当要表示前面提出的某一肯定的情况也同样适合于后者，通常就要用“So+助动词+主语”这种倒装结构。如：
You are young and so am I. 你年轻，我也年轻。
She likes music and so do I. 她喜欢音乐，我也喜欢。
If he can do it, so can I. 要是他能做此事，我也能。
【典型考题】(答案分别为BBA)
1. So difficult _________ it to work out the problem that I decided to ask Tom for advice.
A. I did find B. did I find C. I have found D. have I found
2. _________ about wild plants that they decided to make a trip to Madagascar for further research.
A. so curious the couple was B. So curious were the couple
C. How curious the couple were D. The couple was such curious
3. —It’s burning hot today, isn’t it?—Yes. _________ yesterday.
A. So was it B. So it was C. So it is D. So is it
特别说明(from www.hxen.com)：
(1) 若前面提出某一否定的情况，要表示后者也属于同样的否定情况，则应将其中的so改为neither或nor。如：
You aren’t young and neither am I. 你不年轻，我也不年轻。
She hasn’t read it and nor have I. 她没有读它，我也没有读。
请看考题(答案选D)：
Mary never does any reading in the evening, _________.
A. so does John B. John does too
C. John doesn’t too D. nor does John
(2) 注意“So+助动词+主语”与表示强调或同意的“So+主语+助动词”的区别。如：
“It was cold yesterday.” “So it was.” “昨天很冷。”“的确很冷。”
