英语书面语语法和口语法不大一律，是进修者简单忽略和感触迷惑的场合。一道来看看底下五个语法重心吧。

1.书面语中的句子构造It’s difficult, the exam.
非正式书面语中的语法在某些上面与口语法各别。句子常常不那么搀杂，运用的连词品种更少，也更大略。
正式的口语：
While the hotel was of quite a high standard, the food was disappointing.
非正式的书面语：
The hotel was quite good, but the food was disappointing.
消息常常不妨划分，以一条一条的情势表露——句子并非老是按照主语—谓语—宾语的语序。
They work very hard, the students.
2.简略句子发端Must dash.
在非正式书面语中，常常简略非复读的句子发端。
简略的主假如冠词、主人代词、人称代词、助动词和be动词、引导词和启发性的there is句型。
Car’s running badly. (=The car’s…)
Shoelace is undone. (=My shoelace…)
Forgotten the umbrella again. (=He’s forgotten…)
You talking to me? (=Are you talking…?)
She ready? (=Is she ready?)
Must dash. (=I must dash.)
Won’t work. (=It won’t work)
Be four pounds fifty. (=That’ll be…)
No reason to panic. (= There’s no reason…)
3.简略助动词后的用语“Get up!” “I am!”
在非正式书面语中，常常只用助动词，而不反复较长的表白。
—Get up!—I am. (=I am getting up.)
He said he’d write to me, but he hasn’t. (=…he hasn’t written to me.)
—Talk louder.—I would if I could, but I can’t.
即使没有可反复的助动词，则用 do。
She said she would phone, and she did.
4.附加疑义句It's cold, isn't it?
在书面语或非正式口语中，附加疑义句（question tag）常用来句尾，用来确认某事能否属实，或包括对方承诺。
You haven’t seen Joe, have you?
This tea isn’t very nice, is it?
否认的附加疑义句常常用缩写情势，如 isn’t it（常常不说 is it not?）在附加疑义句中，am I not 的缩写情势是 aren’t I?
Nice day, isn’t it?
I’m late, aren’t I?
5.答语疑义句
答语疑义句（reply question）的形成为助动词+代词（与附加疑义句一致），表白关心、爱好或诧异。
—We had a lovely holiday.
—Did you?
—Yes, we went…
—John likes that girl next door.—Oh, does he?
—It was a terrible party.
—Was it?
—Yes,…
用否认的答语疑义句往返答确定句，表白巩固赞许的口气。
—It was a lovely concert.—Yes, wasn’t it! I did enjoy it.
—She’s lost a lot of weight.—Yes, hasn’t she?
