 [误] How nice the book is! Is it sold well?
 [正] How nice the book is! Does it sell well?
 [析] 有些动词可以表示一种动作,但也可以用来表示某种性质,表示动作时可用被动语态,在表示性质时则不可用被动语态。如:
 This book sells well. 这本书畅销。
 This car drives easily. 这车容易驾驶。
 These clothes wash easily. 这些衣服好洗。
 在作上述表达时,不要用被动语态。而要讲:
 This kind of book was sold out. (这种书卖完了)
 These clothes were washed by the washing machine. 这时要用被动语态,因为它描述的是具体动作。
 [误] Must I do it now?
No. you mustn't.
 [正] Must I do it now? No, you needn't.
 [析] need用在疑问句和否定句中常用作情态动词,其后接不带to的不定式。由must提问的问句作答语时,如是肯定的要用must,否定的要用needn't,即为没有必要。在肯定句中常用作实意动词,如:I need to wait for my boy.
 [误] Is this book yours?
 Yes, It's.
 [正] Is this book yours?
Yes, It is.
 [析] 在肯定的回答中不要用缩写形式,而在否定的回答中可以用缩写形式,如:No. It isn't.
 [误] I'll have my bike repair tomorrow.
 [正] I'll have my bike repaired tomorrow.
 [析] have+人+动词原形或现在分词意为:让某人作某事,如:My father had me to learn how to drive, 或My father had me doing my homework from morning till might have+物+动词的过去分词为某件事被别人完成。如:I have my hair cut.我去理发。而不是自己理发。如果讲我想自己作某事,则用I want to repair my bike myself.
 [误] I'll get my brother repair the bike for you.
 [正] I'll get my brother to repair the bike for you.
 [析] have与get的用法有相同之处,也有不同之处。相同之处,如:have something done, 也可用get something done, 或have (get) somebody doing something但不同之处在于have somebody do something 在用get时则要用get somebody to do something。
 [误] I have to study on Saturday but I haven't to study a full day
 [正] I have to study on Saturday, but I don't have to study a full day.
 [析] have to 不得不,而don't have to 为其否定式。
 [误] Is Tom in the classroom? No. He mustn't be in the classroom, because I saw him talking with our teacher in the office just now.
 [正] Is Tom in the classroom? No. He can't be in the classroom because I saw him talking with our teacher in the office just now.
 [析] must 加动词原形表达一种比较肯定的推测,而表示否定的推测则要用can't。
 [误] My grandpa is over eighty but he is able to read without glasses.
 [正] My grandpa is over eighty, but he can read without glasses.
 [析] can (could) 多用于表达客观的事实,主观能力,而be able to 则多用于表达主观的意愿。
 [误] She doesn't answer the doorbell. She should be asleep.
 [正] She doesn't answer the doorbell.  She must be asleep
 [析] should 用于现在时态的句子中应译为"应该",如:You should do your homework right away. 而 must加动词原形表示一种推测。
 [误] Do you like to go with us?
 [正] Would you like to go with us?
 [析] Do you like…问的是习惯,如:Do you like swimming? 而would you like是一次性的邀请。
 [误] I am used to get up early in the morning.
 [正] I am used to getting up early in the morning.
 [析] used to 共有三种用法,① 表示过去的习惯,如:I used to live with my parents. ② 表示过去的习惯延续到现在,如:I am used to swimming in the river. ③ 用于被动语态,如: Oil is used to cook
 [误] To play with the children are very interesting.
 [正] To play with the children is very interesting.
 [析] 不定式作主语时,应视为单数主语,特别是两个不定式用and作连词作主语时,如指的是一件事也应用单数谓语动词。如:To get up early and to go to sleep early is good for your health.
 [误] He asked me do my homework alone.
 [正] He asked me to do my homework alone.
 [析] 某些动词要求不定式作其宾语或宾语补足语,它们是:ask somebody to do something 要求某人做某事。 tell somebody to do something 告诉某人做某事 还有prepare 准备, decide 决定, happen to 碰巧, seem 似乎。
 [误] he told me to drive a car.
 [正] He told me how to drive a car.
 [析] 要学会疑问词加不定式的用法,特别要注意的是what是疑问代词,而how是疑问副词。如:I want to know what to do. (我想知道干什么)。 I want to know how to do it. (我想知道如何去作)。 要注意的是how to do it 中的it是不可少的,因how是疑问副词,不能作及物动词的宾语,而what是疑问代词,可做do的宾语,所以what to do 后不要加it。
 [误] I am very glad meeting you.
 [正] I am very glad to meet you.
 [析] 许多形容词后加不定式,这样用时形容词多是用来描述人物的感情、态度,如:glad, happy, pleased, lucky, sorry, sad, upset, ready, careful, surprised。
 [误] I'm too glad for seeing you.
 [正] I'm too glad to see you.
 [析] 这句话不能按照too…to的句型翻译为:我太高兴了以至于不想见你。而应译为:见到你太高兴了。又如:She is too honest to tell the truth 应译为:她很诚实,不会不讲实话。
 [误] Tom is too young not to join the army.
 [正] Tom is too young to join the army.
 [析] 这是too…to的正常用法,太如何如何以至于不能如何。
 [误] I went to the hospital for seeing my old friend. He was ill in hospital.
 [正] I went to the hospital to see my old friend. He was ill in hospital.
 [析] 在句中表示某动作的目的时,要用不定式而不能用for加动名词。
 [误] Could you help me to find a chair to sit.
