四、数词 16. There are fourteen hundreds students in our school. Hundred / thousand / million / score/ dozen等词前有具体数字时后不加s，前面没有具体数字时在其后加s 和of，表示大约几百几千的概念。如 two hundred students（两百个学生），hundreds of students（成百上千个学生）。例句中应把hundreds 改为hundred。 17. Their school is twice as larger as our school. 表倍数关系的as---as中间只能用形容词或副词的原级。因此把larger改为large. 18. Today’s homework is a five-hundred-words composition. 几个单词由连字符连接而组成的复合形容词中的名词只能用单数，所以把five-hundred-words改为five-hundred-word. 19. Two third of the students in our school are from America. 英语表达中分数的分子用基数词，分母用序数词，分子大于一时分母后要加s，所以就把third 改为thirds. 五、形容词和副词 形容词和副词容易被误用，形容词和副词的比较级和最高级也是应注意的重点。 20. The patient appeared nervously when he talked to the doctor. appear在此是个系动词，其后应接形容词作表语。所以把nervously改为nervous. 21. The artist worked hardly to finish his drawings on time. 此句需要一个副词来修饰，hardly是副词，但意为“几乎不”，hard 也可以是副词，表努力，因此把 hardly 改为hard. 22. This shirt is more cheaper than that one. More只构成比较级，而不能修饰比较级。因此把more去掉。 23. He is the most successful of the two businessmen. 两者相比较时，比较级前用定冠词，三者或三者以上才用most，因此把most改为more. 24. He works less harder than he used to. 表不如… 时用less加上形容词和副词的原级，因此把harder改为hard. 25. The book is fairly more interesting than that one. fairly只能修饰形容词和副词的原级，可以修饰比较级的副词或短语有：much, even, still, far, a lot, a little, a bit, any, no, by far, rather等，因此把fairly改为rather. 26. This is as an interesting a story as the one in the magazine. as … as中间的词序是as加上形容词加上a(n)加上名词再加上as，因此应改为as interesting a story as the one. 27. The weather here is nicer than Xizang. 同样的事物才能相比较，weather和Xizang不具有可比性，因此应改为The weather here is nicer than that of Xizang. 28.You shouldn't stand too closely to him 有些副词有两种形式，一个与形容词同形，一个以形容词-ly构成，但他们有不同的含义。close靠近、挨近；closely紧密地，紧紧地 29. I would rather take a train than went by bus. 这个词组为would rather do … than do …，因此把went改为go. 30. Is there interesting anything at the meeting? 修饰anything, something, every-thing, nothing的形容词都要放在它们的后面。 31. I never have seen such a person before. 像never之类的副词在句中应放在be动词、助动词之后，实意动词之前。因为应改为I have never seen such a person before. 32. The book is worth to be read. be worth doing 意为值得被做。因此改为The book is worth reading. 33. It is sure that he will succeed. sure 的主语只能为人，而certain的主语可为人和物。因此把sure改为certain. 34. He is regarded as one of the best alive writers at present. alive 为表语形容词，偶尔也做后置定语。因此把alive改为living，或把alive 放在writers后面。 35. I don’t know that he has finished the work yet. yet 用于否定和疑问句，already用于肯定句。把yet 改为already. 36. He said nearly nothing at the meeting. nearly 不与否定词用在同一个句子中，而almost可以。因此把nearly 改为almost. 六、介词 37. He usually goes to school by his father’s car. by加上名词表示一种交通方式，中间什么都不加，如by car, by bus, by plane等；如果名词前有其他的词修饰，则应除by以外的其他介词，此处把by改为in. 38. Please wait me at the school gate. wait为不及物动词，需加介词for后才能再跟名词或代词做宾语。 39. He has been married with Betty for more than twenty years. marry不跟 with连用，应把with改为to。 40. I finished the work on time under the help of him. “在…的帮助下”用with而不用under。 七、情态动词 41. He can be at home now because the light in his room is still on. 表特别有把握的肯定判断时用must，表特别有把握的否定判断时用can, can表判断时只用在否定句中。因此把can 改为must。 42. He need come here before the meeting begins. 作情态动词时need用在否定，疑问和条件句中，不能用于肯定句中，而作实意动词时则可以。所以应改为：He needs to come here before the meeting begins. 43. He used to get up very early in the morning, and now he is still doing so. used to 用来表示过去常常做某事而现在不了，所以应把后半句改为：but now he is not doing so. 44. I needn’t come yesterday because all the work had been finished. 由于情态动词本身不体现时态，所以在谈论过去的事情时在情态动词后加 have done，因此在 needn’t 后加have。 45. You hadn’t better stay up too late because you have to get up early tomorrow. had better 的否定在 better 后面加not. 八、动词的时态 英语的常用时态有十六种，一般根据上下文和时间状语来确定时态。 46. I will tell her about that when she will come tomorrow. 主句为将来时，其时间、条件、方式和让步状语从句中用一般现在时。因此将will come改为comes。 47. The meeting is about to begin in ten minutes. be about to 一般不与具体的时间状语连用。因此把 in ten minutes 去掉。 48. The boy opened his eyes for a moment, looking at the captain and then died. 此处look并非伴随状语，而是三个并列的谓语动词，因此把looking 改为looked。 49. I have bought this bike for ten years and I am still using it now. 当句中有for加一段时间作状语时，谓语动词必须为延续性动词，此处把bought改为kept。 50. I haven’t learnt any English before I came here. 我来这儿已经是过去的动作，在此之前发生的事应该用过去完成时。因此应把haven’t改为hadn’t 九、动词的语态 及物动词用在主动语态时要有宾语，因此可以变为被动语态；不及物动词用于主动语态时不能接宾语，因此无被动语态。 51. The two thieves have been disappeared. disappear 为不及物动词，因此不能用于被动语态。所以把 been去掉。 52. The building built now will be our teaching building. 表“现在正在建的”应用被动语态的正在进行时，因此在built 前加being。 53. He is being operated by the famous doctor. 主动语态变为被动语态时，应注意短语动词的完整性，别忘了介词或副词。“给…做手术”应为operate on sb，所以在operated 后加上on。 54. I wonder if the doctor has been sent. 原因同上，应在sent 后加上for。 55. The book written by him is sold well. 说一本书畅销是指书本身的属性，因此不用被动语态。本句应改为：The book written by him sells well. 56. This history book is worthy reading. “值得被做”可以有如下几种说法：be worth doing; be worthy of being done; be worthy to be done. 因此本句应该为：This history book is worthy to be read.
