［误］She brushed her gold hair carefully.
［正］She brushed her golden hair carefully.
［析］gold作形容词指“金质的”，如：a gold ring, a gold coin, 而golden是“金色的”，如：golden age（金色的时代），但“金鱼”例外，为gold fish.
［误］I've been waiting for good twenty minutes.
［正］I've been waiting for a good twenty minutes.

［误］This food is very good to you.
［正］This food is very good for you.
［析］be good for是“对……有利、有好处”，而be good to是指“对待某人不错”，如：Your friend is very good to me.

4. had better
［误］You have better hurry.
［正］You had better hurry.
［误］You hadn't better worry.
［正］You had better not worry.
［析］had better后面加不带to的不定式，其否定式是“had better not+动词原形”。
［误］I had driven about half mile.
［正］I had driven about half a mile.
［析］“半小时”有两种讲法：half an hour, a half hour. 而“一个半小时”应讲an hour and a half或one and a half hours.“半天”应讲half a day，“半镑”应讲half a pound.但要尽量避免使用half a year，而应用six months；不用half a month, 而用two weeks或fifteen days.
［误］Half us could go to the park.
［正］Half of us could go to the park.
［析］half用于名词前可用of结构也可不用of结构，但用于代词前则必须加of. 如：More than half (of) my classmates are boys.
［误］One and half apples are left on the table.
［正］One and half apples is left on the table.
［析］一个半（one and half）后面的名词要用复数，而句中的谓语动词却要用单数。

［正］Half of the work is done.
［误］Half of the six apples is red.
［正］Half of the six apples are red.
［误］He shook hand with his teacher.
［正］He shook hands with his teacher.

［误］An accident was happened in this street last night.
［正］An accident happened in this street last night.

［误］I have to study hardly.
［正］I have to study hard.
［析］hard是形容词，如：a hard work, 但它同时也是副词。hardly是hard的又一副词形式，但词意截然不同，意为“几乎不”。
［误］I had my leg broken last term, so I couldn't hardly study at all.
［正］I had my leg broken last term so I hardly studied at all.
［析］hardly意为“否定”，所以不要再加否定词语了，如果hardly用于句首则应采用倒装语序，如：Hardly had he arrived when she started complaining.
［误］I had my boy do his homework from morning till noon.
［正］I had my boy doing his homework from morning till noon.
［析］用have somebody do something还是doing something要取决句子的意思和句中的时间状语。
［误］I have my bike to repair.
［正］I have my bike repaired.
［析］ have something done这一句型是让某事被别人去作，请看下面两句意义的不同：I have repaired my bike.（我自己已修好了自行车。）而I have my bike repaired.（我把车推出去让别人修理了。）
［误］Could you give me some money if you have.
［正］Could you give me some money if you have any.
［析］“如果你有的话”一句译为英文应加上any一词，如：I want some books if there is any.
［误］I've got headache.
［正］I've got a headache.
［析］Headache是一个规则的可数名词，所以可以讲：My mother often gets headaches. 但是“牙痛”（toothache），“肚子痛”（stomachache）等却都可以用作不可数名词，如：I've got toothache. 但也可用作可数名词。
