2016学年初二英语暑假作业练习题

暑假初二英语作业答案 篇2

1. 错误类型

经分析后发现, 学生所犯的错误主要是语言知识错误。这类错误主要是指学生对英语语音、语法及词汇知识掌握不牢而犯的错误。概括起来主要有以下几种:

1.1 搭配错误。学生把一些基本搭配弄混淆, 有时候将某些语法规则应用到不恰当的地方。如:

(1) He made me to feel angry.应为:He made me feel angry.

(2) I go to school by a bike.应为:I go to school by bike.

(3) She is good at sing.应为:She is good at singing.

1.2 遗漏。主要表现为一些单词的拼写上面。如:

I am interested in all kinds of activities in our school.

应为:I am interested in all kinds of activities in our school.

1.3 语法规则错误, 如前后不一致, 包括数的不一致, 时态不一致, 主谓不一致等。这是由于学生语法知识掌握不够全面造成的。

(1) Tom as well as his father and mother are very fat.

应为:Tom as well as his father and mother is very fat.

(2) There are a desk, a bed and two chairs in the bedroom.

应为:There is a desk, a bed and two chairs in the bedroom.

(3) Tell me where did you go just now.

应为:Tell me where you went just now.

1.4 混淆错误。学生常常分不清英语里的相似表达或者是一些同义词的用法。

(1) Brain is come from Canada.

应为:Brain comes/is from Canada.

(2) She does not like singing, I don’t like it also.

应为:She does not like singing, I don’t like it either.

2. 错误分析及总结

经过观察及交谈了解后发现, 学生所犯的错误主要是语法错误和词汇错误, 其原因主要有以下几方面:

2.1 学生自身的性格特点

初二学生这个时候正处于青春时期, 性格上有急于求成的心理, 比较急躁, 情绪波动大。笔者在对学生进行辅导的时候发现, 学生在做作业练习的时候书写速度非常快, 很多时候还没有考虑清楚就已经完成答题, 并且字迹比较马虎。这就特别容易造成单词的遗漏现象或者忽略单词的形。学生因为学习的压力比较大, 造成学习的功利心较强, 只注重结果不注重过程, 而一旦结果不如意则心浮气躁, 情绪波动以致无法进行学习。因此, 在学习过程中培养学生细心、稳重的品质并且树立以过程为价值取向的观念非常重要, 在很多时候都能很好的解决问题。

2.2 目标语基础知识不扎实

构建主义认为学习是一种主动的构建过程, 而不是个体获得越来越多外部信息的过程。在语言学习的认知活动中, 学习者不断对客观事物或现象的认知做出各种假设, 并根据已知的知识和经验来验证假设。初二学生之所以出现上述语言知识错误, 就是因为他们根据已有的知识和经验来假设并验证其假设而致。比如学生明白英语里有动词不定式这样的形式, 但是在具体使用的时候却不清楚什么样的词是接动词不定式, 这个时候就容易出现上面的搭配错误, 即将语法规则运用到不恰当的地方。在英语学习中, 英语语法的规则是英语学习的重头戏, 因此要注意在辅导的过程加强对基本知识的梳理, 帮助学生逐渐建构起基本的语法体系, 这样就降低了学生把基本语法弄混淆的可能性。

2.3 母语跟目标语特点的不同

英语和汉语是两个不同的语系, 两种语言相似部分很少, 而相异部份很多。这就对中国学生特别是初学英语的学生产生了很大的干扰。比如在涉及到前后一致问题的时候, 在我们的母语思维里是不存在动词的形, 因此在做题的时候很容易产生这样的定势, 造成顾此失彼的现象。

3. 一些启示

3.1 培养学生养成作业书写的好习惯

作业是一种书写, 一种交流, 一种展示。批阅者或老师是学生作业的目标读者。培养学生良好的书写习惯和态度是需要重视的问题。学生书写的态度和习惯甚至会影响考试的正确率。学生总是忘了句子开头第一个字母要大写的规矩, 再加上青睐跳舞似的书写, 多字少词的现象比比皆是。养成良好的书写习惯不管是对学生态度的端正还是对成绩的提高都是有效的手段。

3.2 养成订正作业的好习惯

通过观察学生的作业发现虽然学生作业上所犯的错误都一一更正过来了, 但是很多类型的错误都是学生一犯再犯的, 这就说明了学生在更正作业错误的时候或许是为了改错而改错, 实际上并没有引起对错误本身的重视。好的订正习惯不仅是有错就改, 更重要的是能自己树立起对错误的认识, 能够分析这个错误的原因, 由此不断的梳理自己的知识结构。因此, 平时可以帮助学生逐渐养成良好的订正习惯, 可以鼓励学生有个订正本或叫纠错本, 把平时作业做错的部分、讲义或试卷等做错的习题誊写到特定的这种本子上, 并且进行错误分析后的感言, 让她自己明白是由于粗心还是由于知识不牢固引起的错误。长此以往学生就能逐渐克服粗心的毛病, 并且能不断的巩固更新已有的知识体系, 这样, 作业的作用也就得到了最大发挥。

Two children stood outside the door with old coats. “Any old papers, Lady?” asked one of them.

I was busy. I wanted to say no, but I saw that their shoes were broken and wet. “Come in and I’ll make you a cup of hot tea.” They came in, saying nothing. Their shoes left snow on the floor.

I gave them tea and bread to protect them against the cold outside. Then I went back to the kitchen and started my housework again.

The silence in the front room surprised me. I looked in.

The girl held the empty cup in her hands, looking at it. The boy asked me in a low voice,“Lady...are you rich?”

“Am I rich? Oh, no!” I looked at my old things in the room.

The girl put her cup back in its saucer (茶碟) carefully. “Your cups match your saucers.”

They left then, holding their papers against the wind. They hadn’t said thank you. They didn’t need to. They had done more than that. The blue cups and saucers were simple. But they said that they matched. The potatoes and meat before me, a roof over our heads, my husband with a job—these things matched, too.

I moved the chairs back from the fire and cleaned the living room. The prints of their small shoes were still wet upon my floor. I let them be. I wanted them there to remind me how rich I was.

A. offer them some warm clothes B. serve them some tea and food

D. the two children were looking for jobs

A. it was snowing outside when the story happened

B. the two children thanked the author and then left

C. the two children were not polite to the author

D. the author had a set of new furniture in her house

Have you ever heard the song called “Is there anyone who told you”? It may be impossible for you not to know the song and its singer. It is sung by the famous “Happy Boy” Chen Chusheng, who appeared on Hunan Satellite TV. He caught everyone’s attention. Before the competition he was just a farmer’s son who had never got professional trainings of any kind. As a child, Chusheng wasn’t a good student, but he was very interested in music. He liked to listen to and sing his favorite songs again and again. Like many other parents, his parents also wanted him to go to college, but he failed. Chusheng had no choice but to help his brother repair bicycles and motorbikes. In Sanya, a small city in Hainan Province, Chen worked during the daytime while singing in different bars in the evening. He lived like that until the year 2000.

In 2000, Chen went to Shenzhen. He never expected that his first job in this new place would be delivering food. He went on working in the daytime while singing in the evenings. His life was hard at that time. In the bar called Star-making Factories he met many famous local musicians. In the following several years, Chen, with his musical dream, attended many music contests throughout the country, winning prizes many times. Today, when we think about his success, we cannot help thinking that if one wants to be successful, he should work harder than others.

( )66. From the passage we know that _______.

A. Chen Chusheng wasn’t very lucky

B. Chen Chusheng’s parents wanted him to be a singer

C. Chen Chusheng became a successful singer because he worked hard

D. Chen Chusheng got more money

A. They wanted him to go to college.

B. They wanted him to be a doctor.

C. They wanted him to repair bikes for his brother.

D. They wanted him to go to bars.

( )68. What was Chen Chusheng’s life in Shenzhen like?

A. Enjoyable. B. Interesting. C. Comfortable. D. Hard.

( )69. What’s the meaning of the word “delivering”?

A. 烹饪 B. 递送 C. 品尝 D. 购买

( )70. Where did he work in the evening in Shenzhen?

A. In a bar. B. In a factory. C. In a restaurant. D. In a supermarket.

D

What is your favourite cartoon? It may be difficult for you to decide. But for the pianist Lang Lang, Tom and Jerry is the best one.

When Lang Lang was two years old, he saw Tom playing the piano. This was his first time to enjoy western music and this experience encouraged him to learn to play the piano.

His talent at the keyboard has taken him from Shenyang to the world.

Lang became a good piano student at three. Ever since, the boy has been doing better and better. In 1997, the 15-year-old boy studied at a famous American Music College.

Lang’s performances are energetic. He is well-known for making facial expressions and moving around while playing the piano.

The road to success has never been easy. Lang’s father stopped his job to look after him, while his mother stayed in Shenyang to make money. But Lang considers himself lucky and believes he should give something back. He has helped the children in poor areas a lot.

初二暑假学习计划表

1、早上起床时间控制在6点至6点半左右,然后马上去做一下运动,大概持续到7点钟(适当的运动有助于大脑血液循环)。然后你吃一下早餐等等的。

2、上午时间大可不必疯狂地做作业。你可以先看一些英文的书(课外的,但是适合初中生的),那样有助于培养语感、积累词汇;然后(大概10点)你可以看一些文学类的课外书(当然不是英文的了)。适当地让自己有一个闲适的生活状态。

再说一下,你可以有针对地看书,上午你也可以看一些自己较弱的学科的书

3、下面说说下午的任务(忘记说了,午饭之前你也可以去运动一下)。下午,人的一般注意力不太容易集中,那么你可以做一些暑假作业,注重理解。因为下午背的东西,一般都不太容易记住。

4、晚上,你不必太紧张,如果稍微勤奋点的话,你可以再做做作业;但我觉得晚上大可以看一下课外书,看一些新闻,或许去散散步。到8、9点时就可以睡觉了

5、总的来说,你一天要有9-10小时的睡眠时间,劳逸结合,才可以有较好的状态去迎接初三。我们一起努力吧!加油!

初二升初三暑假学习时间安排

8:00-9:30初而学生利用暑假期间背古诗及看古文

9:30-11:30预习数学

11:30-14:00吃饭、休息(可看电视,玩电脑)

14:00-15:30词典看字、看书

15:30-17:30初二学生利用暑假期间看一些课外书和英文电影,或和同学户外活动

18:00-19:30看新闻联播,吃晚饭

第⑥课:成长故事

《有梦想才能有成功》:想象是创新的先导。开发自己的想象力,展开现象。首先要“敢于想”,其次要“能够想”,最后要“善于想”。敢于异想天开,科学家告诫我们:“人们‘不可能’做的事,往往不是由于缺乏力量和金钱,而是由于缺乏想象的观念。”其次要“能够想”。想象的火花迸发于丰富的知识矿藏,创造想象尤其需要丰富的知识和经验。没有深厚的知识储备就不会有想象或只是无用的空想。最后要“善于想”。要围绕一点向外发散,朝四面八方想开去,打破常规跳出旧框,任想象不受束缚的自由飞翔。伟大的创新皆起源于人们创造动机的伟大想象。人类文明在想象的神奇力量下不断向前发展,最终使它们变成现实。

《成功并不像你想象的那么难》:唯物主义辩证法认为一切事物都是前进性与曲折性的统一,而总的趋势是前进的,道路是曲折的,在前进中有曲折在曲折有前进。要正确对待人生中的曲折,要对前途充满信心,正确的认识困难,树立正确的人生观、价值观,勇敢的面对困难。正确对待困难时为了让自己更好地树立方向和目标,使自己明白自己的不足,并加以完善走向成功。但如果夸大困难,会使自己惧怕困难,唯恐自己不能成功,而最终放弃。做任何事都不可能一帆风顺,难免会遇到困难。正确的对待困难会成为前进的动力。夸大困难会使人有一种渴望不可及之感而丧失信心。

解:(1)设甲、乙两种花木的成本价分别为x元和y元.

由题意得: 2x+3y=1700

3x+y=1500

解得: x=400

y=300

(2)设种植甲种花木为a株,则种植乙种花木为(3a+10)株.

则有: 400a+300(3a+10)≤30000

(760-400)a+(540-300)(3a+10)≥21600

解得:160/9≤a≤270/13

由于a为整数,

∴a可取18或19或20.

所以有三种具体方案:

①种植甲种花木18株,种植乙种花木3a+10=64株;

②种植甲种花木19株,种植乙种花木3a+10=67株;

③种植甲种花木20株,种植乙种花木3a+10=70株.

(2) 1.2(300-x)m≥4/5×300m

1.54mx>1/2×300m

解得97又31/77(这是假分数)

∵x为正整数,

∴x可取98,99,100.

∴共有三种调配方案:

①202人生产A种产品,98人生产B种产品;

②201人生产A种产品,99人生产B种产品;

③200人生产A种产品,100人生产B种产品;

∵y=0.34mx+360m,

∴x越大,利润y越大,

∴当x取最大值100,即200人生产A种产品,100人生产B种产品时总利润最大.

(1)设该种纪念品4月份的销售价格为x元.

根据题意得2000/x=(2000+700/0.9x)-20,

解之得x=50,

经检验x=50所得方程的解,

∴该种纪念品4月份的销售价格是50元;

(2)由(1)知4月份销售件数为2000/50=40件,

∴四月份每件盈利800/40=20元,

5月份销售件数为40+20=60件,且每件售价为50×0.9=45,每件比4月份少盈利5元,为15元,所以5月份销售这种纪念品获利60×15=900元.
