had better ��

　　［誤］ You have better hurry.��

　　［正］ You had better hurry.��

　　［析］ had better只用過去時had，不要誤用成現在時have。��

　　［誤］ You hadn‘t better worry.��

　　［正］ You had better not worry.��

　　［析］ had better后面加不帶to的不定式，其否定式是"had better not+動詞原形"。��

　　half ��

　　［誤］ I had driven about half mile.��

　　［正］ I had driven about half a mile.��

　　［析］ "半小時"有兩種講法half an hour, a half hour. 而"一個半小時"應講an hour and a half或one and a half hours."半天"應講half a day，"半鎊"應講half a pound.但要盡量避免使用half a year，而應用six months；不用half a month, 而用two weeks或fifteen days.��

　　［誤］ Half us could go to the park.��

　　［正］ Half of us could go to the park.��

　　［析］ half用于名詞前可用of結構也可不用of結構，但用于代詞前則必須加of。如：More than half (of) my classmates are boys.��

　　［誤］ One and half apples are left on the table.��

　　［正］ One and half apples is left on the table.��

　　［析］ 一個半one and half后面的名詞要用復數，而句中的謂語動詞卻要用單數。��

　　［誤］ Half of the work are done.��

　　［正］ Half of the work is done.��

　　［誤］ Half of the six apples is red.��

　　［正］ Half of the six apples are red.��

　　［析］ "half of+名詞"這一結構后面的謂語動詞應與of后面的名詞相一致，如為不可數名詞或可數名詞單數，要用單數謂語動詞；而復數名詞后面要加與復數相對應的謂語動詞。��

　　hand ��

　　［誤］ He shook hand with his teacher.��

　　［正］ He shook hands with his teacher.��

　　［析］ 與某人握手要用shake hands. 與hand有關的詞組中有很多要用復數形式，如：change hands (轉手、易手)，in the hands of (由……控制)，join hands (與人合作)。��

　　happen ��

　　［誤］ What was happened to you last month?��

　　［正］ What happened to you last month?��

　　［誤］ An accident was happened in this street last night.��

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

　　［析］ 在英語中不及物動詞沒有被動態，作為"發生"講的happen，take place和break out都不具有被動態。happen to常用來表達一件偶然發生的事，如：If you happen to meet my sister please ask her to call me.��

　　hard ��

　　［誤］ I have to study hardly.��

　　［正］ I have to study hard.��

　　［析］ hard是形容詞，如：a hard work，但它同時也是副詞。hardly是hard的又一副詞形式，但詞意截然不同，意為"幾乎不"。��

　　［誤］ 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意為"否定"，所以不要再加否定詞語了，如果hardly用于句首則應采用倒裝語序，如：Hardly had he arrived when she started complaining.
