初一英语考试结束后,对英语试卷进行分析十分重要。下面读文网小编为大家带来初一英语试卷分析,希望对你有所帮助。
一,听力题第四节 语篇理解 第20题,他没填对。错误原因:录音语速快,没听清这个空的词,快速听力练的少,也不排除紧张心理在作怪。
二 ,书面测试第二大题单项选择第25题:It's Mike's-----birthday today .His classmates have a party for him and they are very happy ,
A, three B, thirteen C, thirteenth
他 选了B, 答案应为C。错误原因:这里是用序数词来限定Mlik具体的年龄,不能按中国人的思维去理解,要从英文的语言习惯和语法上去理解。
三, 书面测试第六大题补全对话第68题,他的答案是:When is your birthday ?正确答案应为:Her birthday is in September .
错误原因:粗心大意,只看下句就回答上句,没考虑全文的上下衔接,没关注最后的标点符号,关注标点符号,一定要 注意细节,这是我在平时讲课时常提醒的,结果还是没注意到,要学会全方位思考问题,学习就是这么严谨的事情。
四,书面测试第七大题连词成句第74题:原题是: has, my ,father ,,milk ,for ,breakfast ,always
他的几次答案分别是:1,My father breakfast always has for milk.
2, My father breakfast always for has milk.
3, My father always breakfast for has milk.
正确答案:My father always has milk for breakfast.
分析其错误原因如下:句子意义明白,在语法结构方面思维混乱,按中国人的语言习惯去思考连句,平时的朗读背诵还得加强,有利于培养英文的语感,英文的句子一般将时间状语,地点状语甩在句尾,这也是讲课多次提到的。要学会随时扭转思维,适应中英文语言转换。
另外他把has翻译成有,一个英文单词翻译成中文有多种意义,具体应该翻译成什么要根据整个句子的含义和整篇文章的含义而定。
五,书面测试第五大题B部分词汇运用题。第二句话 我让他翻译,他把Have a look at the clothes.中的 have不加思索地翻译成有, Have a look at 是英语中的固定搭配,单词不能单独的解释,是一个完整的含义,看一看,证明他平时词组积累不到位。他把We sell shirts for only 80 yuan .译成:我们的裙子只有80元。他把skirt和shirt又混了,前者是短裙,但后者是衬衫!应该译成:我们的衬衫仅售80元。
又帮他积累了一些固定答配:
be at a good price be at great sale
六,书面测试第五大题第59空,他把图上画的梨看成了草莓, ,填错,而且这个地方要注意名词变复数问题,这个句子中重点词汇是two 。他把pear 拼成了price,这是很多学生的共性,相类似的单词总爱张冠李戴,究其原因就是心情浮躁,急躁,学习不是非常严谨细心的态度而造成的。
七,一些重读闭音节单词动词变动名词的一些规律也要求他点滴积累,我希望我教给学生的更多的是方法,培养他们更多的良好的学习习惯,从点滴做起,点滴积累:
如:swim----swimming , sit ----sitting , shop---shopping . put----putting 等等。要求他自己今后进行相关积累。
八,以字母o 结尾的名词变复数问题:
巧记以o 结尾的名词的复数形式
名词单数变复数,本不是个太难的问题。谁都知道在一般情况下加s,其他的如以s,x,ch,sh结尾的加es。但对以o结尾的名词,如 hero(英雄),piano(钢琴),bamboo(竹),solo(独唱)这一类,到底是该加s,还是该加es,常使中学生困惑不解。我们可按下面一条规律来记住它们的复数形式:指人和农作物的加es、其他的加s.(或者是有生命的加es,无生命的加s)
如下面单词加es
Negro—Negroes (黑人)
hero—heroes (英雄)
tomato—tomatoes (西红柿)
potato—potatoes (土豆)
而下面的单词加s
photo—photos (相片)
zoo—zoos (动物园)
radio—radios (收音机)
piano—pianos (钢琴)
单词tobacco(烟草),coo(鸽子咕咕叫声)却不适用这一条。
这里再介绍一个帮助记忆的好方法。张道真先生编的《实用英语语法》中写道:“以o结尾的词多数都加es,但下面两类只加s”:
(1)词末为两个元音字母的词
(2)某些外来词
这样,凡外来词则加 s.如 photos,solos,pianos,kilos(千克),tohaccos。凡词尾以两个元音结尾的词则加 s.如:zoos, bamboos,coos, radios, studios(艺术家的工作室)。
除此而外,其他的都加 es,如 echoes(回声),torpedoes(鱼雷)。

相信大家对现在完成时都很了解, 不过说到过去完成进行时或许大家就会有疑惑.现在小编给大家整理这两个时态的区别,让大家对过去完成时和现在完成时有更多的了解.
现在完成时(Present perfect)过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态。
过去完成时(past perfect)①表示发生在过去的动作对现在造成的某种影响影响或结果②过去某动作一直持续到现在将来可能还要延续下去。句中的动作发生在过去之前(过去的过去),即过去完成时动作发生在过去的过去。
He said he had been to Beijing twice. 他说他已经去过北京两次。(因为“说”said就是过去式,而去北京的动作发生在说said 的过去,所以用过完而不用现完。
现在让我们来比较一下现在完成时和现在完成进行时。在比较这两个时态时,关键在于对现在完成进行时的基本概念是否理解,因为对于现在完成时我们已经有了一个基本的理解了。
现在完成进行时是一兼有现在完成时和现在进行时二者基本特点的时态。由于它有现在完成时的特点,所以它可以表示某一动
作对现在产生的结果或影响。由于它有现在进行时的特点,所以它也可以表示某一动作的延续性、临时性、重复性、生动性乃至感情色彩。
现在就现在完成进行时的这些特点和现在完成时作一简单的比较:
(1)现在完成进行时和现在完成时皆可表示动作对现在产生的结果,但前者所表示的结果是直接的,而后者所表示的则是最后的结果。如:
We have been cleaning the classroom.(a)
We have cleaned the classroom.(b)
(a)句可译为“我们打扫教室来着。”其直接结果可能是:我们身上都是灰。(b)句可以译为“我们把教室打扫过了。”
其结果是:现在教室很清洁,可以用了。又,(a)句表示教室刚刚打扫过,(b)句则可能表示教室是昨天打扫的。
Be careful! John has been painting the door.(a)
John has painted the door.(b)
(a)句表示约翰刚刚把门油漆过,现在油漆还未干,所以你要小心。(b)句则无此含义,油漆可能已干了。
(2)现在完成进行时有时有延续性,现在完成时往往没有。如:
They have been widening the road.(a)
They have widened the road.(b)
(a)句的意思是他们在加宽马路,但尚未完工。(b)句的意思则是已完工了。有时现在完成时有延续性(如一些属于持续体的动词),但无临时性质。如:
Mr. Smith has been living in London since 1978.(a)
Mr. Smith has lived in London since 1979.(b)
(a)句有“史密斯先生在伦敦久居”的含义,(b)句则没有。
(3)但现在完成进行时并不总是具有临时的性质,如:
My mother has been teaching English for twenty years.(a)
My mother has taught English for twenty years.(b)
(a)句在此并无临时性质,但较口语化。(b)句则较为正式。又,(a)句表示动作现在仍在继续.并将延续下去,(b)句的动作是否延续下去,须由上下文决定,但在一般情况下都是延续下去的。
(4)现在完成进行时往往表示动作在重复,现在完成时则常常不带重复性。如:
Have you been meeting her lately?(a)
Have you met her lately?(b)
(a)句有“经常相会”之意,(b)句则没有。(b)句如与often,every day等时间状语连用,当然也表示动作在重复。
(5)现在完成进行时比较生动,有时含有明显的感情色彩,而现在完成时往往只说明一个事实,一种影响或结果,平铺直
叙,没有什么感情色彩可言。如:
What have you been doing?(a)
What have you done?(b)
(a)句表示惊异。(b)句只是一个问题。
Have you been waiting long?(a)
Have you waited long?(b)
(a)句较(b)句生动。又,(a)句比较口语化。
I have been wanting to meet you for long.(a)
I have long wanted to meet you.(b)
(a)句比(b)句更亲切,更有礼貌。
Recently Mary has been doing her work regularly.(a)
Recently Mary has done her work regularly.(b)
(a)句显然是在表扬玛丽。(b)只说明一个事实。
