【摘要】：2013六级考试进入了最后的冲刺阶段，以下是精品学习网特为考生们整理了2013英语六级语法关于may，might和more总结。预祝考生们通过考试!
1) 表示允许或请求;表示没有把握的推测;may 放在句首，表示祝愿。
May God bless you!
He might be at home.
注意： might 表示推测时，不表示时态。只是可能性比may 小。
2) 成语： may/might as well，后面接不带to 的不定式，意为"不妨"。
If that is the case, we may as well try.
典型例题
Peter ___come with us tonight, but he isn‘t very sure yet.
A. must B. may C. can D. will
答案B. 表可能性只能用may. 此句意可从后半句推出。
1) the more… the more…越……就越……
The harder you work，the greater progress you'll make.
2) more B than A与其说A不如说B
less A than He is more lazy than slow at his work.
= He is less slow than lazy at his work.
3) no more… than… 与……一样……，不比……多
The officials could see no more than the Emperor.
no less… than…与……一样……
He is no less diligent than you.
4) more than不只是，非常
She is more than kind to us all.
典型例题
1)The weather in China is different from____.
A. in America B. one in America C. America
D. that in America
答案：D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家，C不能选。A没有名词，后句成分不全，排除。B和D中，B中的one常用来代替可数名词，而that可车以代替不可数或抽象名词，所以选D。
2)After the new technique was introduced，the factory produced ___ tractors in 1988 as the year before.
A. as twice manyB. as many twiceC. twice as manyD. twice many as
答案C. 此句意为"这个厂1988能生产的拖拉机是往年的两倍"。 表示倍数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为C。
This ruler is three times as long as that one.
