四、數詞
16. There are fourteen hundreds students in our school.
Hundred / thousand / million / score/ dozen等詞前有具體數字時後不加s，前面沒有具體數字時在其後加s 和of，表示大約幾百幾千的概念。如 two hundred students（兩百個學生），hundreds of students（成百上千個學生）。例句中應把hundreds 改為hundred。
17. Their school is twice as larger as our school.
表倍數關係的as---as中間只能用形容詞或副詞的原級。因此把larger改為large.
18. Today’s homework is a five-hundred-words composition.
幾個單詞由連字符連接而組成的複合形容詞中的名詞只能用單數，所以把five-hundred-words改為five-hundred-word.
19. Two third of the students in our school are from America.
英語表達中分數的分子用基數詞，分母用序數詞，分子大於一時分母后要加s，所以就把third 改為thirds.
五、形容詞和副詞
形容詞和副詞容易被誤用，形容詞和副詞的比較級和最高級也是應注意的重點。
20. The patient appeared nervously when he talked to the doctor.
appear在此是個系動詞，其後應接形容詞作表語。所以把nervously改為nervous.
21. The artist worked hardly to finish his drawings on time.
此句需要一個副詞來修飾，hardly是副詞，但意為“幾乎不”，hard 也可以是副詞，表努力，因此把 hardly 改為hard.
22. This shirt is more cheaper than that one.
More只構成比較級，而不能修飾比較級。因此把more去掉。
23. He is the most successful of the two businessmen.
兩者相比較時，比較級前用定冠詞，三者或三者以上才用most，因此把most改為more.
24. He works less harder than he used to.
表不如… 時用less加上形容詞和副詞的原級，因此把harder改為hard.
25. The book is fairly more interesting than that one.
fairly只能修飾形容詞和副詞的原級，可以修飾比較級的副詞或短語有：much, even, still, far, a lot, a little, a bit, any, no, by far, rather等，因此把fairly改為rather.
26. This is as an interesting a story as the one in the magazine.
as … as中間的詞序是as加上形容詞加上a(n)加上名詞再加上as，因此應改為as interesting a story as the one.
27. The weather here is nicer than Xizang.
同樣的事物才能相比較，weather和Xizang不具有可比性，因此應改為The weather here is nicer than that of Xizang.
28.You shouldn't stand too closely to him
有些副詞有兩種形式，一個與形容詞同形，一個以形容詞-ly構成，但他們有不同的含義。close靠近、挨近；closely緊密地，緊緊地
29. I would rather take a train than went by bus.
這個詞組為would rather do … than do …，因此把went改為go.
30. Is there interesting anything at the meeting?
修飾anything, something, every-thing, nothing的形容詞都要放在它們的後面。
31. I never have seen such a person before.
像never之類的副詞在句中應放在be動詞、助動詞之後，實意動詞之前。因為應改為I have never seen such a person before.
32. The book is worth to be read.
be worth doing 意為值得被做。因此改為The book is worth reading.
33. It is sure that he will succeed.
sure 的主語只能為人，而certain的主語可為人和物。因此把sure改為certain.
34. He is regarded as one of the best alive writers at present.
alive 為表語形容詞，偶爾也做後置定語。因此把alive改為living，或把alive 放在writers後面。
35. I don’t know that he has finished the work yet.
yet 用於否定和疑問句，already用於肯定句。把yet 改為already.
36. He said nearly nothing at the meeting.
nearly 不與否定詞用在同一個句子中，而almost可以。因此把nearly 改為almost.
六、介詞
37. He usually goes to school by his father’s car.
by加上名詞表示一種交通方式，中間什麼都不加，如by car, by bus, by plane等；如果名詞前有其他的詞修飾，則應除by以外的其他介詞，此處把by改為in.
38. Please wait me at the school gate.
wait為不及物動詞，需加介詞for後才能再跟名詞或代詞做賓語。
39. He has been married with Betty for more than twenty years.
marry不跟 with連用，應把with改為to。
40. I finished the work on time under the help of him.
“在…的幫助下”用with而不用under。
七、情態動詞
41. He can be at home now because the light in his room is still on.
表特別有把握的肯定判斷時用must，表特別有把握的否定判斷時用can, can表判斷時只用在否定句中。因此把can 改為must。
42. He need come here before the meeting begins.
作情態動詞時need用在否定，疑問和條件句中，不能用於肯定句中，而作實意動詞時則可以。所以應改為：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 用來表示過去常常做某事而現在不了，所以應把後半句改為：but now he is not doing so.
44. I needn’t come yesterday because all the work had been finished.
由於情態動詞本身不體現時態，所以在談論過去的事情時在情態動詞後加 have done，因此在 needn’t 後加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 後面加not.
八、動詞的時態
英語的常用時態有十六種，一般根據上下文和時間狀語來確定時態。
46. I will tell her about that when she will come tomorrow.
主句為將來時，其時間、條件、方式和讓步狀語從句中用一般現在時。因此將will come改為comes。
47. The meeting is about to begin in ten minutes.
be about to 一般不與具體的時間狀語連用。因此把 in ten minutes 去掉。
48. The boy opened his eyes for a moment, looking at the captain and then died.
此處look並非伴隨狀語，而是三個並列的謂語動詞，因此把looking 改為looked。
49. I have bought this bike for ten years and I am still using it now.
當句中有for加一段時間作狀語時，謂語動詞必須為延續性動詞，此處把bought改為kept。
50. I haven’t learnt any English before I came here.
我來這兒已經是過去的動作，在此之前發生的事應該用過去完成時。因此應把haven’t改為hadn’t
九、動詞的語態
及物動詞用在主動語態時要有賓語，因此可以變為被動語態；不及物動詞用於主動語態時不能接賓語，因此無被動語態。
51. The two thieves have been disappeared.
disappear 為不及物動詞，因此不能用於被動語態。所以把 been去掉。
52. The building built now will be our teaching building.
表“現在正在建的”應用被動語態的正在進行時，因此在built 前加being。
53. He is being operated by the famous doctor.
主動語態變為被動語態時，應注意短語動詞的完整性，別忘了介詞或副詞。“給…做手術”應為operate on sb，所以在operated 後加上on。
54. I wonder if the doctor has been sent.
原因同上，應在sent 後加上for。
55. The book written by him is sold well.
說一本書暢銷是指書本身的屬性，因此不用被動語態。本句應改為：The book written by him sells well.
56. This history book is worthy reading.
“值得被做”可以有如下幾種說法：be worth doing; be worthy of being done; be worthy to be done. 因此本句應該為：This history book is worthy to be read.
