2. That girl loves reading book.
3. He went into a book’s shop and bought a dictionary.
一般表示有生命的东西的名词的所有格用’s，如my mother’s car, 而此处适宜用名词修饰名词，改为a book shop.

一些集合名词如看成一个整体，则用单数的谓语动词，如My family is a happy>
5. I bought some potatos and tomatos at the supermarket.
中学阶段以“o”结尾的名词中有四个词变复数时要加es，它们是tomato, potato, Negro, hero; 其余的都加s变为复数。
6．This has nothing to do with their believes.（这和他们的信仰没关系。）
以f, fe 结尾的词变为复数时一般去f, fe 加ves，如knife—knives, thief—thieves; 而roof 和belief直接加s变为复数。所以应把believes改为beliefs.
7. The boss wants to hire an useful person.
用a还是an，取决于后面单词的第一个音标，如为元音用an，为辅音用a。useful的第一个音是辅音所以应把an改为a。类似的，我们说a European country.
8．Plane is a machine that can fly.
Plane为可数名词单数，不能单独放在句中，应在其前加冠词或把它变为复数，而本句后有a machine, 因此只能在其前面加a，变为A plane。

把a 改为the ，因为乐器前用定冠词。
10．The machine was invented in 1920s.
在in后加the，因为表示年代用in加the再加几十的复数，如在八十年代in the 80s。

15．These books are mine; those in the bag are her.

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.
18．Today’s homework is a five-hundred-words composition.
19．Two third of the students in our school are from America.
20．The patient appeared nervously when he talked to the doctor.
21．The artist worked hardly to finish his drawings>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>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.
24．He works less harder than he used to.
25．The book is fairly more interesting than that>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
26．This is as an interesting a story as the>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>

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.
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.
34．He is regarded as>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.
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.
39．He has been married with Betty for more than twenty years.
40．I finished the work>“在…的帮助下”用with而不用under。
41．He can be at home now because the light in his room is still>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.
46．I will tell her about that when she will come tomorrow.
47．The meeting is about to begin in ten minutes.

49．I have bought this bike for ten years and I am still using it now.
50．I haven’t learnt any English before I came here.

54．I wonder if the doctor has been sent.
55．The book written by him is sold well.
book written by him sells well.

58．The girl dressed herself in red is my sister.
59．Being seriously ill, his class-mates sent him to hospital.

现在分词的否定应把not放在现在分词前面，所以前半句应改为：Not having seen her for many years.
61．Seeing from the space, the earth looks like a ball.
62．English is easy to learn it.
63．I will get somebody repair the recorder for you.
“让某人做某事”可以有以下几种表达法：make sb do sth; have sb do sth; get sb to sth. 因此在repair 前加to。
64．She decided to work harder in order to not fall behind the others.
不定式的否定把not放在to前面。因此应改为：She decided to work harder in order not to fall behind the others.
65．It’s better to laugh than crying.

66．It’s no use to send for the doctor.
做某事是没用的要说成It’s no use doing,所以把to send 改为sending。
67．She practices to play the piano after school every day.
practise 后只跟动名词作宾语，因此把to play 改为playing。
68．When the teacher came in, he stopped listening to the teacher.
stop doing 为停止做这件事，而stop to do 为停下来正在做的事去做这件事。所以后半句应该为：he stopped to listen to the teacher.
69．We are talking about if this plan should be carried out.
If 和whether都可以引导动词的宾语从句，如果从句做的是介词宾语，只能用whether引导。所以把if 改为whether。
70．I can not decide if to stay or not.
71．My suggestion is we try for a second time.
72．What will the professor say is not known yet.
名词性从句的语序都是陈述句语序。因此应改为：What the professor will say is not known yet.
73．I will go unless he invites me.
此句意为“除非他邀请我，否则我不去。”而unless相当于if not, 所以本句应改成：I won’t go unless he invites me。
74．Although he tried, but he still couldn’t keep up with the others.
although 和but 不能同时用在一句话中，去掉任何一个都可以。
75．I won’t stay until he comes back.
含有not…until的句子的谓语动词应是点动词，含有until的肯定句的动词应是延续性动词，此句有两种改法：I will stay until he comes back.或I won’t leave until he comes back.

77．This is the very thing which I lost yesterday.

80．This is the place where we visited last year.
81．I, who is your friend, can understand you.
82．China is a developing country, that is known to all.
非限定性定语从句的引导词永远不会是that，因此把that 改为which 或as。
83．The poet and writer are invited to give a speech at the meeting.
84．No>主语后加except再加上若干数量的名词，谓语动词和主语保持一致。所以把know改为knows。类似的用法的词或短语有：but, besides, with, together with, along with, as well as等等。
85．Your clothes is>clothes为复数句词，谓语动词应为复数。把is改为are。

87．The class was watching TV when I entered the room.
88．The population of our country are increasing slowly now.
population 单独作主语谓语动词经常用单数；如果其前有分数或百分数，而且后面又有复数名词时谓语动词用复数。如：One fifth of the Chinese population are workers. 此处把are改为is。
