no more than not morethan ?
no more than应译为"只不过"、"才"，如： He wrote no more than three books. 即他真正写了三本书。而not more than则意为"不会多于"，如： He wrote not more than three books. 即他写的书不会多于三本。又如： He is no shorter than you. 应译为"你和他都不矮"，而He is not shorter than you. 才应译为"他比你高。"?
most ?
［误］ Most of students are good at English.?
［正］ Most of the students are good at English.?
［正］ Most students are good at English.?
［析］ most of这一结构后面的名词前一定要有一个限定词。?
［误］ My friends are most teachers.?
［正］ My friends are mostly teachers.?
［析］ mostly意为"大部分的"，"主要的"。?
much ?
［误］ The boy was asleep very much.?
［正］ The boy was fast asleep.?
［析］ 不是所有的形容词都可以用very来修饰，如fast asleep意为"熟睡"，则是固定搭配。像interesting, exciting, surprising这些形容词化的现在分词，以及tired, interested这些形容词化的过去分词则要用very来修饰。?
must ?
［误］ He must be in the office, and mustn't go home.?
［正］ He must be in the office, and can't go home.?
［析］ must加动词原形为对事情的肯定推测，而否定的推测则要用can't加动词原形。?
［误］ It must have rained now.?
［正］ It must have rained yesterday.?
［析］ "must+have+过去分词"为对过去发生事情的推测。这句话应译为"昨天一定是下雨了。"又如： I must go and call him. He must have forgotten it.?
must have to ?
must用来表示说话者觉得某件事有必要去做，如I must stop smoking. 其意为：我自己认为我要戒烟；而have to则多用来表达由于来自外界的因素而不得不去做的事，如： I have to go to school tomorrow.?must无过去式，当用在讲过去某件必须要做的事时要用had to, 如： When I was young, I had to go to the factory.?在否定句中mustn't意为：一定不要做某事，如： You mustn't tell this to Tom. 而haven't to则多意为没有必要去做，如： You don't have to tell this to Tom. 而英语中多用needn't 来取代haven't to.?
myself ?
［误］ I can't play ping?pong myself.?
［正］ I can't play ping?pong by myself.?
［析］ 第一句并无语法错误，myself为"我亲自要去"，而by myself为"独自一人"。这句话要表达的意思是"我一个人无法打乒乓球。"而I want to play ping?pong myself. 应译为"我自己想去打乒乓球。"?
