1、初中英语 100 个易错知识点，考试经常出现！ 01 名词 写作中，同学们常把握不好名词的数、所有格以及一些集合名词的用法。 1. He gave me a very good advice yesterday. 句中的 a 要去掉，因为 advice 是不可数名词。一些汉语概念为可数的词在英语中却是不可数的， 表示数量时在其前加 a piece of， 类似的词有： news, bread, work, paper, chalk, furniture, information 等等。 2. That girl loves reading book. 可数名词单数不能孤零零地放在句子里，或前面
2、加冠词，或将其变为复数。此处最好变为 books. 3. He went into a books 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 mothers car, 而此处适宜用名词修饰名词，改为 a book shop. 4. My family is watching TV. 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 one; 如强调集合中每个个体的个人行为，则用复数的谓语动词。此处看电视是个体行为，应把 is 改为 are。类似的词有：team, class, aud
3、ience 等。 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。 6This 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 knifeknives, thiefthieves; 而 roof 和 belief 直接加 s 变为复数。 所以应把 believ
4、es 改为beliefs. 02 冠词 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. 8Plane 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。 9He played a piano at the
5、 party yesterday. 把 a 改为 the ，因为乐器前用定冠词。 10The 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。 11Xiao Hong went to school by the bus every day. 去掉 the，因为表示交通方式用 by 直接加交通工具。 03 代词 使用代词时请注意其单、复数，主、宾格以及形容词性物主代词和名词性物主代词的用法。 12He is one of those speakers who make his
6、 ideas perfectly clear. 定语从句的先行词是 those speakers，为复数，因此从句中的指示代词应为复数，应把 his 改为 their。 13 Whom do you think has left the lights on？ 放在疑问句特殊疑问词后的 do you think / believe / guess / imagine / suppose 等都不参与句子成分，把它们去掉后，疑问词在句中做主语用主格，做宾语用宾格。本句中去掉 do you think 后缺的是主语，应把 Whom改为 Who。 14The boss pretended not to
7、see John and I. John 和 I 在句中都做的宾语，应把 I 改为 me。 15These books are mine; those in the bag are her. Her 是形容词性物主代词，后面应该加名词 books，或把 her 改为 hers。 04 数词 16There 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 hu
8、ndred 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。 17Their 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. 18Todays 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-w
9、ord. 19Two 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. 05 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。 20The 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. 21The artist work
10、ed 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. 22This 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。 23He 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. 24He works l
11、ess 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. 25The 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. 26This is as an interesting a story as the
12、 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. 27The 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. 29I would rather take a train than went by bus. 这个词组为 would rather do
13、than do ，因此把 went 改为 go. 30Is 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。 31I 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. 32The book is worth to be read. be worth
14、 doing 意为值得被做。因此改为 The book is worth reading. 33It 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. 34He 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。 35I dont know that he has finished the w
15、ork yet. yet 用于否定和疑问句，already 用于肯定句。把 yet 改为 already. 36He 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. 06 介词 37He usually goes to school by his fathers 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.
16、 38Please 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。 39He has been married with Betty for more than twenty years. marry 不跟 with 连用，应把 with 改为 to。 40I finished the work on time under the help of him. “在的帮助下”用 with 而不用 under。 07 情态动词 41He can be at home now because the light in hi
17、s 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。 42He 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. 43He used to get up very early in the morning, and now he is s
18、till 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 neednt 后加 have。 45You hadnt better stay up too late because you have to get up early tomorrow. had better 的
19、否定在 better 后面加 not. 08 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。 46I 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。 47The 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。 48The boy opened his eyes for
20、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。 49I 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。 50I havent 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
21、应把 havent 改为 hadnt 09 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。 51The 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。 52The 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。 53He is being operated by the famou
22、s 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。 54I wonder if the doctor has been sent. 原因同上，应在 sent 后加上 for。 55The 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. 56This history book is worthy reading. “值得被做”
23、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. 10 非谓语动词 57We are going to talk about the problem discussing at the last meeting. 此处为分词作定语，问题应该被讨论，所以把 discussing 改为 discussed。 58The girl dressed herself in red is my sister. dre
24、ss 为及物动词，意为“给穿衣服”，此处为分词作定语修饰 girl, girl应是它的逻辑宾语，因此把 herself 去掉。 59Being seriously ill, his class-mates sent him to hospital. 分词作状语时，其逻辑主语为这句话的主语，此句应为“因为他病了，他的同学才把他送到医院去”，因此把前半句改为：He being seriously ill. 60Having not seen her for many years, we could hardly recognize her. 现在分词的否定应把 not 放在现在分词前面，所以前半句
25、应改为：Not having seen her for many years. 61Seeing from the space, the earth looks like a ball. 分词作状语，其逻辑主语应是这句话的主语，此句中地球应该被看，所以把 Seeing 改为 Seen。 62English is easy to learn it. 此句中是不定式作状语修饰 easy, English 应该是 learn 的逻辑宾语，所以把 it 去掉。 63I will get somebody repair the recorder for you. “让某人做某事”可以有以下几种表达法：m
26、ake sb do sth; have sb do sth; get sb to sth. 因此在 repair 前加 to。 64She 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. 65Its better to laugh than crying. 表比较时比较的双方应为同种结构，或都是名词或都是不定式。因此有两种改法：It
27、s better to laugh than to cry 或 Its better laughing than crying. 66Its 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。 67She 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。 68When the teacher came in, he stopped liste
28、ning 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. 11 名词性从句 69We 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。 70I can not decide if to stay or not. 只有 wheth
29、er 才能和不定式搭配使用。因此把 if 改为 whether。 71My suggestion is we try for a second time. 表语从句的引导词如为 that，一般不省略。因此在 we 前加上 that。 72What 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. 12 状语从句 73I will go unless he invites me. 此句意为“除非他邀请我，否则我不去。”而 un
30、less 相当于 if not, 所以本句应改成：I wont go unless he invites me。 74Although he tried, but he still couldnt 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。 75I wont stay until he comes back. 含有 notuntil 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 wont leav
31、e until he comes back. 13 定语从句 76An orphan is a child whos parents are dead. 定语从句中表“的”引导词只有 whose，所以把 whos 改为 whose。 77This is the very thing which I lost yesterday. 如果先行词为物且前有 the only, the last, the very 修饰时，定语从句的引导词只能用 that。 78This is the car for that I paid a high price. 定语从句的先行词为物，而且引导词放在介词后时，只
32、能用 which. 79She is one of the students who has passed the exam. 定语从句修饰 one of 加上复数名词时，复数名词是定语从句的先行词，因此把 has 改为 have。 80This is the place where we visited last year. 定语从句的先行词用关系代词还是关系副词要看定语从句中缺不缺主语或宾语，如缺用关系代词，如不缺用关系副词。此句中 visit 为及物动词，后无宾语，因此把 where 改为 which 或 that。 81I, who is your friend, can unders
33、tand you. 定语从句的谓语动词应与其先行词保持一致，因此把 is 改为 am。 82China 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。 14 主谓一致 83The poet and writer are invited to give a speech at the meeting. poet 和 writer 共用一个冠词，指的是一个人身兼二职，所以谓语动词应为单数。把 are 改为 is. 84No one except my paren
34、ts know it. 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。 85Your clothes is on the table over there. clothes 为复数句词，谓语动词应为复数。把 is 改为 are。 86. The number of the students in that school are about one thousand. 此名的主语为 numbe
35、r 而不是 students。因此把 are 改为 is。 87The class was watching TV when I entered the room. class 作主语时，把它看成一个整体时谓语动词用单数，看成每一个成员的个体行为时谓语动词用复数。一般来说，一些具体行为如看电视、吃饭、洗澡等都属于每一个成员的个体行为。此处把 was 改为 were。 88The 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
36、。如：One fifth of the Chinese population are workers. 此处把 are 改为 is。 15 倒装 89No sooner he had reached the station than the train left. no sooner 为否定副词，放于句首时句子要部分倒装，因此此句应改为：No sooner had he reached the station than the train left. 90Here comes he. here 放于句首时，句子主谓要完全倒装，但句子主语为代词时，则主谓不倒装。此句应改为：Here he com
37、es. 91A child as he is, he can speak five languages. 用 as 引导让步状语从句，可把形容词、副词和不带冠词的名词放于 as 前。所以前半句改为：Child as he is. 16 虚拟语气 92She would have come if we invited her. 这是与过去事实相反的虚拟假设，从句应该用过去完成时。所以在 we 后加 had. 93My suggestion is that we would send a few people to help them. suggestion 的表语从句也应用虚拟语气，必须用 sh
38、ould 加动词原形，should 可以省略。此处去掉 would 或把 would 改为 should。 94The secretary wishes that she has time to type the letter now. wish 后的时态应该把真实时态往后推一个时态，所以把 has 改为 had。 95Its time that we go to bed. 句式为 Its time sb did sth 所以把 go 改为 went。 96I would rather you have another try tomorrow. 词组为 would rather sb did
39、 sth. 所以把 have 改为 had。 17 there be 句式 97There are a bag and several books on the table. There be 句式遵循谓语动词就近原则， a bag 为单数， 所以把 are 改为 is。 98There were several people stood at the back of the room. There be 句式的谓语动词为 be 动词，句中其他的动词应为非谓语动词。所以把 stood 改为 standing. 18 修饰语在句中的位置不当 99We almost have written twenty compositions this term. 像 almost 这样的副词在句中放在助动词、be 动词之后，实意动词之前。因此把 almost 放在 have 后面。 100 The girl has beautiful, silky hair who lives high in the mountains. 定语从句应紧跟先行词，所以改为：The girl, who lives high in the mountains, has beautiful, silky hair.
