小事情大道理作文1我们身边,有许许多多的小事情,可能是你在公交车上让出了自己的座位,可能是你把路边的垃圾拾起来扔进垃圾桶里,可能是……不禁让我想起了很久很久以前的一件事。

有一次我在家里帮妈妈洗碗,洗着洗着,突然手一滑,碗从我手里掉了下来,咔嚓一声,碗碎了,我立马就慌了,怎么办?怎么办怎么办呀?妈妈听见了,边走便问:"尹然,怎么了?"我一听见妈妈过来了,脸立马就变白了,心想:总之,不能让妈妈知道。

于是,我大声喊了一声:"妈,没事,勺子掉了,"说完,我闭上了眼睛,现在只有两种结果,一种是妈妈过来,发现碗碎了,批评我一顿,要么是妈妈回卧室去了,等了一会,奇迹发生了,妈妈回到了卧室,我的心一下放松了,一下坐到了地上:好了,现在想想怎么处理这件事吧。

我看着地上的碎片自言自语到。

结果想来想去也想不出什么好办法,我就把那些碎片扫到柜子里的角落去了。

过了几天,我都要把这事忘了,可有一天,妈妈在打扫家,我在看电视,突然听见妈妈叫了一声,我跑过去一看,妈妈的手指被划破了,旁边还有我上次打碎的碗。

妈妈问怎么回事,我只能说出了真相,但妈妈没有责怪我,反而给我讲了许多的道理,但有一条我永远忘不了:有些东西可以掩盖事实,但事实一定会浮出水面,做错了事,只要你及时认错,就是好样的。

小事情大道理作文2我的童年是快乐的,有个快乐的妈妈和疼爱我的爸爸。

六年级数学期中考试后的反思总结(精选10篇)

六年级数学期中考试后的反思总结(精选10篇)

六年级数学期中考试后的反思总结六年级数学期中考试后的反思总结(精选10篇)总结是事后对某一阶段的学习或工作情况作加以回顾检查并分析评价的书面材料,它可以提升我们发现问题的能力,不妨让我们认真地完成总结吧。

那么如何把总结写出新花样呢?下面是小编收集整理的六年级数学期中考试后的反思总结范文,仅供参考,大家一起来看看吧。

六年级数学期中考试后的反思总结篇1本次考试使我对六年级学生数学水平有了大致的了解,突出数学课程的基础性、普及性和发展性,使数学教育面向全体学生。

为了更深入全面的了解我所任的数学教学的效果,吸取经验教训,更有针对性的开展各项教学研究工作,特将本次考试试卷进行分析。

一、试卷说明1、内容和形式:这次期中考试的内容是小学数学第十一册位置、分数乘除法和圆的周长。

这张试卷与以往相比,在试题类型和叙述方式上没有变化。

2、难度:试题按难度分为容易题、中等题和稍难题,三种试题分数比大致为4:3:3,整体来说比平时试题要稍难一些。

应用题30分。

3、考查知识及能力:这张试卷考查的知识涵盖本册教材的重点分数知识,侧重分数乘、除法数学问题的解决。

计算题考查一些分数的乘除的计算,填空也是分数、比的概念;另外还考查了“位置”中的图的移动变化情况。

4、试卷特点:题型结构合理,难度偏高。

填空题和应用题稍有偏难。

二、试卷分析我校参加这次六年级数学考试的共26名同学,我对他们的及格率和优秀率作了如下统计:及格率50%,优秀率 19.2 %,平均分60.73分,最高分97 分,最低分12分,且有两个。

从统计的这些指标看,成绩完全没有达到了我的预期。

我对各大题的得失分情况作了统计,从六年级的试卷情况反映出以下几个问题:1、学生分析问题的能力不强。

失分最严重的就是应用题,由于学生的分析问题的能力不强,不能很好的理解题意,所以失分较为严重。

好多学生根本没有理解自己求出来的是什么,(例如很简单的分数问题中根据题意写出数量关系都写不出来,甚至单位“1”的量也找不准。

高考英语二轮复习新高考题型组合练习:新高考组合练15基础篇

高考英语二轮复习新高考题型组合练(八)基础篇15阅读理解A、B篇+七选五+语法填空+应用文写作【阅读理解A篇】A(2022·北大附中期中)When I was 12 years old, I already knew that my teen years were going to be the worst years of my life. I was a total outsider, bullied at school. I felt completely alone in my small town. But by starting to do volunteer work when I was 14, I turned my problem into helping others. The opportunity to practice kindness made me feel like my life had a greater purpose. The more positive energy I shared, the more kindness and appreciation I received. I realized that my purpose in life would be to reach out to people, specifically teenagers, and help them feel less alone.Books were my true friends back then. I was so thankful that the authors wrote those books. The kindness they offered me with their books saved my life. One of my biggest dreams was to become an author so I could write books that would help other teenagers the way those books helped me.After surviving terrible experiences at school and at home, I made a choice to take the optimistic and positive road in the next steps of my journey. My dream carcer, which I thought was only possible for the authors I loved, is what I am doing now. I have been a full-time author of teen novels since 2007 and am grateful for this amazing opportunity to reach out to readers every single day.Kindness saved me when I needed help the most. Even small acts of kindness can change someone’s life. You never know what someone else is going through. But by practicing daily kindness, you become an architect of positive change.1.

I jumped out of bed in a little bit of panic. I woke up my 8-year-old daughter Avy, who was not exactly in a hurry to get out of bed. “We’re late for school,” I half-yelled at her. I finally got her into the shower, dressed her hurriedly and made it to the nearby bus stop in time. Thankfully, the school was only two stops away. We got in, rubbing our eyes as the sunlight streamed into the bus.Her mom had flown to Hong Kong several days earlier on assignment for a newspaper to cover the handover of the city’s return to China.I had taken off from work for a week to help look after our daughter. I would pick up my daughter from school around midday. At the end of the day, I would watch the news on TV, which would lead the entire week with the historic events happening in Hong Kong. I would wonder where my wife was in the crowd that was gathered to witness the handover.The year, 1997, was tense because the Asian financial crisis began. The Thai baht was hit, followed by the South Korean won and, like a contagious virus which spreads rapidly, the financial system seized up. For that week though, that was the least of my worries. I just made sure we did not have a repeat of July 1, when we were nearly late for school. My wife was very busy during the handover, chasing down stories in Hong Kong as the British flag was lowered for the last time.I later spent a few years working in Hong Kong, but my enduring memory of the days surrounding its return to China was the time I spent as a babysitter, although it is kind of hard to call an 8-year-old a baby. The whole thing was a lifetime ago. But it is a good memory.4. What was the author’s day like on July 1, 1997?A. He and his daughter woke up in panic.B. He barely got his daughter on time.C. It was his first babysitting day.D. His daughter went to school energetically.5. Why did the author ask for a leave?A. He wanted to witness the historic events.B. He needed to take care of his daughter.C. He drove his daughter to school and pick up her back around midday.D. He accompanied his daughter to find her mother on TV in the evening.6. Which of the following caused the nervousness in 1997?A. The events happening in Hong Kong.B. The crowd gathered to see the handover.C. The spread of the Asian financial crisis.D. The 8-year-old daughter I was babysitting.7. What is the passage mainly about?A. The historic events in 1997.B. Life of a journalist’s husband.C. A working dad’s way of babysitting children.D. Bitter sweet memory with daughter alone.【七选五】(2022·江淮十校二模)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

期中考试语文试卷分析总结与反思(精选14篇)

期中考试语文试卷分析总结与反思(精选14篇)

期中考试语文试卷分析总结与反思(精选14篇)期中考试语文试卷分析总结与反思(精选14篇)在日新月异的现代社会中,我们要有很强的课堂教学能力,反思过去,是为了以后。

反思应该怎么写才好呢?以下是小编帮大家整理的期中考试语文试卷分析总结与反思,希望能够帮助到大家。

期中考试语文试卷分析总结与反思篇1我们班学生全部参加考试,优秀率30%,及格率96.7%。

总的来说,本次考试成绩不算理想,主要是学困生太多了,他们的成绩太差。

逐题看过学生的试卷后,综观学生答题情况,我针对学生各方面的掌握情况做以下分析及反思:一、试卷题型分析本次试卷题型分为:字词、句子、课文、阅读、作文五大项,知识涉及面广,考查了学生基础知识、阅读、习作几个不同方面的知识。

二、学生考情分析(一)基础知识部分从本班试卷的总体情况来看,学生对于基础知识的掌握比较牢固,这与平时的严格要求有关,要继续发扬。

尽管如此,还是出现了一些不该有的错误。

第1题,根据拼音写字成词,虽然说这是最简单的题目,但越是简单的就越容易失误,我仔细数了一下,全对的只占全班的三分之一,这与期中考试没有复习有关,但也说明平日里要多让学生回顾前面学过的知识。

比如:盛誉,学生写成了“声誉”,暴露出学生的拼音能力,需要继续加强练习。

学生对“燥”和“躁”区分不开,需要注意平日对生字的掌握。

第5题,选择正确答案,学生普遍完成不好。

这一题考查学生的理解能力。

要求选出能形容郑和远航这一历史意义的成语,学生不能正确选出。

这说明平日里要多加强对学生多方面知识与能力的培养。

(二)阅读部分这一部分分为课内阅读和课外阅读。

课内阅读,学生对于已经学过的课文内容的理解也能基本到位。

失分较多的是用不但而且写句子,其实学生都知道,只是有的同学语言组织不够连贯,有的没有审清题。

所以平日上课时是要让更多的学生张开口,并且训练学生说完整的话。

课外阅读,失分相对较多,如给短文加题目,概括短文内容等题做的很不好。

学生理解不到位,有的学生态度也不端正。

语文期中考试分析总结(精选5篇)

语文期中考试分析总结语文期中考试分析总结(精选5篇)总结是对过去一定时期的工作、学习或思想情况进行回顾、分析,并做出客观评价的书面材料,它可以帮助我们总结以往思想,发扬成绩,我想我们需要写一份总结了吧。

总结怎么写才能发挥它的作用呢?下面是小编整理的语文期中考试分析总结(精选5篇),仅供参考,欢迎大家阅读。

语文期中考试分析总结1一、试卷特点本试卷命题本着努力体现新课标中新理念的原则,除考查学生应该掌握的基础知识外,还增加了一些开放性、实践性的考查,注重考查学生的语文综合实践能力,紧密联系学生生活实际,难易适当,题型丰富,覆盖知识面广,对以后的学习有引领和促进作用。

二、存在的问题及原因分析(一)字、词、句积累运用1、看拼音写词语,此题中个别字出错率较高,如“挺拔”的“拔”,写成了“拨”,茁壮的“壮”和形“。

状”的“状”填颠倒。

这也看出教师在教学过程中对于字的偏旁和同音字强调不够。

2、选正确读音,放假(jiǎjià)和兴奋(xīngxìng),这两个字出错较多,平时也训练过,但仍有一部分同学出现错误,说明在平时训练时缺乏反复性的练习。

3、补充词语,并选一个造句。

补充短语,正确率很高,极少部分同学有错别字现象,但失分较多,原因是大部分同学没有造句。

分析原因一是题中没有留出造句的空,二是学生根本没有把题目要求放在心里。

要引导学生仔细阅读要求,严格按要求做题。

4、写与动物有关的成语,基本上都能写出,有个别学生有错别字现象。

5、写句子有的学生打比方和把小鸟当作人写不清,都写成了比喻句,因而失分。

6、选字的意思,正确率较高。

7、排序一部分同学排错,原因是不能静下心来认真分析句与句之间前后联系。

(二)根据课文内容填空此题较灵活,死板的内容少,要学以致用,要会概括、归纳、活用,但有很多同学太死板,故乱填,造成失分。

(三)阅读1、是课内阅读,失分率低。

2、是课外阅读,失分率高。

说明学生对文章内容不够理解。

我们该怎么写总结呢?以下是小编整理的语文考试总结(通用8篇),希望能够帮助到大家。

语文考试总结篇1我叫xxx,在xx次考试中,我考了xx分,全班平均分是xx分,最高分是xx,我的语文成绩比最高分差xx分,比平均分差xx分,在班里位居xx名。

综合分析,此次考试存在以下问题:第一:思想不重视。

认为这次考试是小考,没有意义,对付对付就完了。

但是正是我轻视的思想造成了此次考试不好的结果。

平时我的语文成绩不错,在班里居中上游。

第二:从此次考试中,发现自己的基础知识不扎实。

在基础知识项目被扣xx分,占全部被扣分数的xx%。

原以为自己的基础知识扎实,其实不然,给自己敲了警钟。

第三:从考试中,发现自己上课没有集中精神听老师讲课。

因为很多老师讲的内容出现在考试中,而自己没有听讲,所以不会。

由以上几点,我决定在今后的学习中,做到:第一:重视每一次考试,当成练兵,积累自己的考试经验;第二:平时加强自身的基础知识的学习,不可满足于现状;第三:上课注意听讲,认真记笔记我保证,在以后的语文考试中,一定要提高自己跌语文成绩,希望老师和同学们帮助我、监督我!一次考得并不理想,但是我相信自己的实力。

下一次考试,我一定会努力的!语文考试总结篇2一、试卷情况:本次检测的试卷,能紧贴教材,既考查了学生对于课本知识的掌握情况,又充满了人文的关怀,关注了学生心灵的成长。

既鼓励学生自主探究又强调阅读的积累运用,同时还注重了习题的拓展延伸,学用身边的语文资源等,体现了现代教育的理念。

题型结构的安排,分数比例的分配也非常合理,除了对基础知识的掌握,基本能力的培养考察之外,还注重了对学生灵活运用知识,综合素质及创新能力的考察,份量适中,有一定的梯度。

二、学生考试的基本情况分析:我班共有学生36人,参加考试人数36人,从试卷的题型来看,符合二年级孩子的特点。

期中考试后学习计划(精选6篇)

期中考试后学习计划时光在流逝,从不停歇,很快就要开展新的工作了,是时候开始写计划了。

相信许多人会觉得计划很难写?以下是小编整理的期中考试后学习计划(精选6篇),仅供参考,希望能够帮助到大家。

期中考试后学习计划篇1期中考试考完,还没等成绩出来,我已经预料到这次考试的惨败,我认为让这次考试惨败和这几点有关:1、考试前没有好好复习2、考试时心理状态不佳,非常紧张3、考试时精神状态异常不好,没精打采,根本没有心思考试,只想赶快把题做完,结束考试4、在考试的时候有部分题目不会做,放在后面来做,结果后面没有时间,也忘记还有这些剩余的题目成绩次日就下来,结果非常令人惊讶,简直不可思议,卷子错误连篇,叉叉随处可见,上次期末222名,这次中期考试竟然409名,直线下降187名,接近翻番,如果在后半期还是这样的状态,留在宏志班是没有希望、完全不可能的,因为在我后面还有许许多多的人想到宏志班来,而我在后退,他们在前进,所以我在后半期一定要努力,做到这几点:1、每天所有的课余时间均拿来学习、做作业、看书,上厕所除外。

2、提高每次作业质量,包括语文、数学、英语等其它科目,尽自己的力量完成会做的题目。

3、做作业认真审题,遇到选择题、填空题不乱写乱填,坚决做到先审题再思考最后再答题,不盲目的猜。

4、回家在没有必要的情况下,不使用电脑,在有关学习的情况下才使用电脑。

5、上课不和同桌及其周围的人讲话,在上课时不理睬与课堂无关的谈论、事件。

6、上课尽量精力集中,不发呆、坐飞机。

7、不在上课的时候睡觉,特别是数学课的时候。

8、不在上课时做与本堂课无关的事情,例如在数学课上做其它科目的作业之类。

9、改变我自暴自弃、破管子破摔的观念。

这9点,我一定要在这在校的四十多天中坚持下去,争取考到前200名,留到这个集体,时间已经不多,难道在这剩余的四十多天中,我都不能坚持么?孔子说吾日三省吾身,就是告诉我们要学会反思,找到自己的问题,然后改正,否则期中考试也就失去的它真正的意义。

小学期中考试试卷分析总结与反思(精选11篇)

小学期中考试试卷分析总结与反思(精选11篇)

小学期中考试试卷分析总结与反思小学期中考试试卷分析总结与反思(精选11篇)在学习、工作、生活中,课堂教学是我们的任务之一,所谓反思就是能够迅速从一个场景和事态中抽身出来,看自己在前一个场景和事态中自己的表现。

反思应该怎么写呢?以下是小编收集整理的小学期中考试试卷分析总结与反思,欢迎大家借鉴与参考,希望对大家有所帮助。

小学期中考试试卷分析总结与反思篇1一、试题内容及考核目的分析此次考试卷的命题内容为“三大块”:一是日积月累;二是阅读理天地;三是习作乐园。

此次的内容突出了学段的特点,重视考查学生对词句的理解、美文的积累和句子语法的运用能力,同时也检测学生的阅读理解和习作表达能力,体现了新的语文课程标准精神和要求。

二、考试结果及分析(一)总体分析本次的测试内容相对来说较为基础,重视教材中的知识点积累。

参加测试的学生共有37人,及格人数33人,及格率为89.19%。

85分以上19人,优秀率为51.35%。

从测试的成绩看,结果不是很理想,尤其是后进生较多,而当中有两位学生只有二、三十分,试卷上较多的空白;而优生这一头也不是很明显,高分考得不是很多,看来得狠下心来抓两头、促中间。

(二)板块分析日积月累[答题分析]第二题:读拼音写词语。

这一题完成得不够理想,主要问题是没有拼读完音节就匆匆写上去,胶卷的“卷”多出一横,旅行的“旅”右半个没写对。

对于这些基础的知识绝对不能放松,多多巩固和加强。

第五题:选词填空。

这一道题是近义词的辨析,都有过练习,但完成得不够理想,出现了较为低级的错误。

如:耐心、细心、虚心有好几个学生抄下来时只抄下了一半,说明学生在考试时还不够仔细、认真。

第六题:补充句子。

这一道题目中的习题均出自语文园地中的日积月累及经典课文,但学生在完成过程中,写出了很多的错别字因而失分。

[问题剖析]1、字词的基础问题应该加强、高度重视。

从测试中发现,学生对于拼音这一基础知识掌握的不是很好,尤其是几位后进生,对于这些基础性的知识几乎空白没写。

精选期末总结作文6篇

精选期末总结作文6篇精选期末总结作文6篇总结是在一段时间内对学习和工作生活等表现加以总结和概括的一种书面材料,他能够提升我们的书面表达能力,不妨坐下来好好写写总结吧。

总结怎么写才能发挥它的作用呢?以下是小编精心整理的期末总结作文6篇,供大家参考借鉴,希望可以帮助到有需要的朋友。

期末总结作文篇1这一学期马上就要到头了,明天,我们就要放寒假了,我们来说一说这一学期的总结吧。

这一学期,我在语文上有了进步。

比如说,我认识了很多字。

并且有很多进步,也学到了很多写出好的方法。

比如说做引用、反问、设问等等这些写的方法。

这些将来都对我都有用。

而且,我学到了很多词的意思,这有都有用处的。

咱们再说说数学吧。

数学第一次期中考试我考了个满分。

第二次期末考试,我考了113。

5分从中,我懂了一句话的意思,这句话就是:骄兵必败。

意思就是说骄傲的兵必定会输的。

我就当过那个骄傲的兵。

所以我下学期绝对不能骄傲自满。

而且要努力。

争取下一学期可以在数学的方面有所收获,并且,那上奖。

最后我们说一说我英语收获了什么,我英语学到了很多新单词,和新的句型。

过新年的时候,就可以和别人用应来祝贺别人了。

另外我还要说一说我在特色班的收获,我在特色班的收获呢是我学会了吹很多曲子,并且学会了高音怎么吹。

并且,我考试时获得了一个好成绩。

明年就可以上舞台了。

这就是我这学期的收获。

期末总结作文篇2期末考试过后,当我看到我很不理想的成绩后,觉得自己很不好,因此我总结好久,回顾当天晚上我并没有好好复习。

这个教训我永远记在心中。

这个教训就像刀割一样,落在我的身上,给我带上深深的伤痕。

这是老师进教室,原来的喧哗的教室一下子变得安静起来。

老师原来慈祥的目光不见而我们看见的是一双愤怒的眼睛。

而我们知道老师是因为我们考的成绩不好而生气的。

回到家里,我一句话都没有说,默默的医生不吭地走进屋里,我觉得我很对不起我的爸爸合我的妈妈,觉得他们言语我整整十几年,我却还给他们不是很理想的成绩。

期中考试后的反思与总结800字(通用7篇)

期中考试后的反思与总结800字(通用7篇)

期中考试后的反思与总结800字(通用7篇)随着社会不断地进步,教学是我们的工作之一,反思自己,必须要让自己抽身出来看事件或者场景,看一段历程当中的自己。

反思应该怎么写才好呢?以下是小编为大家整理的期中考试后的反思与总结800字(通用5篇),欢迎大家借鉴与参考,希望对大家有所帮助。

期中考试后的反思与总结篇1时间似流水,学期以经过半,期中考试也已来临,而就是短短两天,期中考试也结束,我自信满满的走进考场,却唉声叹气的走出了考场,可这是因为什么呢,为了能让下次的考试考好,我做了一次小结。

我一向数学很好,可是这次鬼使神差的考了那么点分数,翻开卷子一看,红红的大叉一个接着一个,看的我额头直冒汗,再仔细一看,这些题目没一道不会做的,不是计算错误就是审题不清,犯的竟都是低级的错误;而语文在基础题上居然扣了好几分,这让我心痛不已,发誓下次考试之前绝对不再吊儿郎当的,一定要好好复习基础知识,而作文则也扣了不少的分数,整篇文章苍白无力,像是在打流水账,可是我也很无奈呀,肚子里啥都没有,想写也写不出来,我不由暗暗后悔,决定一定要听老师的话,坚持每天写日记并增加阅读量;再看看英语呢,我就更是欲诉无门了,这儿没加“S”,那儿忘记了问号,分数毫不留情面的被减去了,可是没有一体是我不会的,这都是粗心大意结果,可是我现在也回天无力了,我不由得一拍脑袋,心中有一种欲哭无泪的无力之感,我嗟悔无及,告诫着自己下次一定要认真检查,绝能再这么浮躁。

我知道这次考试老师和家长都对我有着很大的期望,可是我让他们失望了。

对于这点我感到十分抱歉。

但通过这次考试我也发现了自己不足点,俗话说的好,有失必有得嘛。

首先我要改掉考试不认真读题不仔细的坏习惯。

我做题时总是只看了前面一半后边的要求还没看到呢,答案便已近写了上去,往往会使我失分。

这也许和答题技巧有关系,但总之我在以后的考试过程之中一定要审题认真,仔细读题,把题目看准、看好。

时间允许的时候要多检查几遍,绝对不允许自己再犯类似于此的无谓的错误。

物理期中考试反思600字(精选17篇)

物理期中考试反思物理期中考试反思600字(精选17篇)在办理事务和工作生活中,教学是重要的任务之一,所谓反思就是能够迅速从一个场景和事态中抽身出来,看自己在前一个场景和事态中自己的表现。

那么应当如何写反思呢?以下是小编帮大家整理的物理期中考试反思,欢迎阅读与收藏。

物理期中考试反思篇1在这次的期中考试中,我所任教的班级均分是72.1分,不算理想。

本次考试,试卷是由市教研室提供的,涵盖了上半学期的全部知识,有力地考察了学生的知识与技能,是一张较好的试卷。

通过对卷面的分析,可以看出上一阶段教学中的得失,现分析如下。

肯定的方面。

基础知识大部分掌握较好,有一定的信息处理能力;对物理学中的人文历史有正确的了解;物理实验器材的使用方法掌握较好。

分析下来,在平时的教学中强抓基础及非常关注知识的生成过程密不可分。

存在的问题。

从卷面得分率最低的18题可看出,学生在对物理中单位换算的能力还是比较薄弱;再从得分率相对低一点的第7、9、13、16、25分析,这几题的得分率在0.6左右,而这几题有个共同的特点就是,在“判断下列说法错误或正确”,学生失分,说明对一些知识的理解还存在理解不透彻的问题;物理计算题向来是学生容易失分的地方,我所带班级学生没有出现放弃解题的情况,失分主要是不能准确的运用物理学科特有的解答过程进行解答,突出表现在有原始公式即有依据但没有变形公式,个别人仍用小学的算术题的形式解答,由于缺少说理依据而失分;最后的探究题,又再次暴露出学生的语言表述能力的不足,有不少同学意思差不多,但表述很不严密,前言不搭后语,还有不能正确的审题,最后要求用“测量的物理量”表示,而学生没搞清“测量量”的意义,把计算整理的量即过程量代入,导致失分。

总体分析下来,存在的问题概括为两点:1、基础知识不扎实,导致理解偏差。

2、科学的表述能力欠缺,导致表述质量不高。

面对暴露出来的问题,接下来将在下面几个方面改进。

1、在强抓基础知识的同时,注意适时改变方法,加强相近知识之间的辨析,并通过一些测试及时反馈学生的掌握情况。

B—1Reading is a good habit, but the problem is, there's too much to read these days, and too little time to read every word of it. There are hundreds of skills to help you read more in less time. Here are two skills that I think are especially good.Preview-----if it's long and hard. Previewing is especially useful for getting a general idea of heavy reading like long magazine articles and business reports.Here's how to preview.●Read the first two paragraphs and the last two paragraphs carefully.●Then read only the first sentence of the other paragraphs.Previewing doesn't give you all the details. It keeps you from spending time on things you don't really want--or need--to read.Skim-----if it's short and simple. Skimming is a good way to get a general idea of light reading like popular magazines or the sports and entertainment of your daily paper.Here's how to skim.●Get your eyes to move fast. Sweep them across each line.●Pi ck up only a few key words in each line.Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we'll get a similar idea of what it's all about.51. How many skills are mentioned in this passage?A. One.B. Two.C. Three.D. Four.52. What should we NOT do when we read sports news in a daily paper according to the passage?A. Read the last two paragraphs carefully.B. Get our eyes to move fast.C. Sweep our eyes across each line.D. Pick up only a few key words in each line.53. What is the best title for this passage?A. How to read fasterB. What to readC. When to readD. Why we should read51. B 52. A 53. AB —2Yesterday my son ,daughter and I went to the grocery store. In front of us in line was a little girl with her mother. The little girl was asking her mother for a box of Smarties. The polite way she was asking almost broke the mother’s heart, “I’m sorry, Honey, but we have no money to buy it.”My son was watching that dialogue. By the way, he had been raking(用耙子耙)leaves in our garden to raise himself some money to buy a bike. As he watched the mother and daughter leave the store, he ran to the candy counter(柜台)and bought a box of Smarties with his money.He turned to look at me and I just nodded. He ran out after the little girl and her mother, and he gave them the box. He came back and told me what he told them, “Every kid should have a pack of Smarties because they can make you smart.”I was so excited that I bought a pack of Smarties for my son. I told him that I was proud of him, and that was for his act of generosity(慷慨)because he gave his own Smarties to others. Quickly, he replied, “But you do nice things for people and you never get anything for it.” I explained , “ when you do something nice for someone ,you shouldn’t expect to get anything ,but when you do get something you should be very thankful.”51.

So he decided to prepare for the show.Brian did a great job at the talent show. Everyone loved his performance, and he won the first prize! His teachers and friends were proud of him. Even so, Ken told Brian that he was not funny, and that he would never be successful. Brian didn’t understand why Ken said so, but he realized that it had nothing to do with him. He confidently continued to work towards his goal.As the years went on, Brian met more people like Ken. “You’ll do a terrible job,” they said to him. Luckily, most people encouraged him and some helped him to become even funnier. He got a lot of opportunities to perform in movies. He was even invited to appear on television.

When I bought it, I wastold it would bloom(开花)and the sweet smell would fill my office.I had the plant for two months, and every day I looked at it, but thereweren't any flowers or pleasant smell. I was not happy, so I gave theplant to my friend Linda.One day, another friend Mary called and invited me to her office. When I walked in, her jasmine flowers surprised me. I reached out to touch the flowers. Mary cut some and gave them to me. I couldn't help smelling them. Surrounded by the sweet smell of only a handful of these flowers, I suddenly understood something.Mary bought her plant the same time I did. It took a year for her jasmine to bloom. I was so impatient for mine to bloom; regretfully, I gave it away.In a way my life is like the jasmine plant. I need to be patient and let things happen.Last Sunday Linda told me that she was going abroad the next week. Before she left, she returned the plant to me. This time I am going to wait.

Well, to tell you the truth, it is really an eye-open experience to study here. In China, I had English classes five times a week since Grade Five. However, I didn’t know how different textbook English could be from everyday English until I came t o Hotchkiss School, Connecticut. When I first studied English, I was told to say, “I’m fine.” when people say “How are you?” but in the US, I found that people say, “I’m good.” or “I’m tired.” One day, someone greeted me with “What’s up?” It made me confused. I thought for a moment and then smiled because I didn’t know what to say. Since then, I have discovered more and more differences between Chinese and US cultures. I was surprised by how hardworking US students are. In China, schoolwork is almost everyt hing, so we study hard and that’s it. But here, a “good’ student gets good grades, does a lot for the public and plays sports or music. The kids here are so clever, I am starting to feel sorry that I gave up playing the piano at an early age and that I have never thought about sports.52. The writer went to America to ____.A. visit an English classB. study in a schoolC. feel American cultureD. learn to play the piano53. The writer thinks that textbook English is ____ everyday English.A. easier thanB. as interesting asC. different fromD. made up of54. What does the underlined word “confused” mean in Chinese?A. 困惑的B. 惊奇的C. 扫兴的D. 开心的51. A 52. B 53. C 54. AB—6You need 3D glasses to see some films. I think it is easy to make yourown 3D glasses instead of buying them.There are two ways to make 3D glasses. You can decide which way would be easier for you.The first way seems like the cheaper way but the things needed to make the glasses this way may not be things laying around the house. First print out a template (模板) for the glasses at /PDF_files/3dglasses.pdf.After you cut out the template, cut your cellophane (玻璃纸) to fit the holes in the glasses. Make sure you place the red cellophane on the left eye and the blue on the right. You can either stick or tape the cellophane in place. You are now ready to use your glasses.To learn more about why your eyes see different colors, read this article: /sterea/anaglyphs.htm#redcyan.To learn some more cool things about your eyes, check out the games at this link: /chudler/chvision.html.Another way you can make 3D glasses is to find an old pair of sunglasses. Take out the lenses (镜片). Get a piece of clear plastic and place the lenses on it,draw a line around the lens and then cut the new plastic lens out. Place the lens back into the sunglasses frame (框). Color the left lens red with a marker and the right eye blue. You now are ready to watch 3D films.36.When do we need to use 3D glasses?A. When the sun is bright.B. When we cook dinner.C. When we make things.D. When we see some films.37.If we want to know why our eyes see different colors, we can find the information at _______.A. /PDF_files/3dglasses.pdfB. /sterea/anaglyphs.htm#redcyanC. /chudler/chvision.htmlD. /tresearch/XCindex/index.js38.What does the writer think of making our own 3D glasses?A. Easy.B. Hard.C. Interesting.D. Boring.52 — 54 DBAB—7Some people think only school children do not agree with their parents, however, it is not true.Communication is a problem for parents an d children of all ages. If it’s hard for you to communicate with your parents, don’t worry about it. Here are some advice f or you to bridge the generation gap (代沟).●Don’t argue (争辩) with your parents.Don’t get to your parents when you are angry. Your parents probably won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go someplace to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don’t think you can speak to them at the moment, try writing a letter.●Try to reach a compromise (和解). Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect to them. Showing respect will keep your relationship strong.●Talk about your values.The values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life.A good relationship with your parents can make you a better and happier person. It is worth having a try!52. Your parents probably won’t consider your ideas if you _______.A. don’t get to them oftenB. write a letter to themC. do n’t speak to them politelyD. express yourself well53. If there’s really a generation gap between you and your parents, you’d better_______.A. have a talk with them oftenB. keep away from themC. agree with them all the timeD. know about their values54. From the passage we learn that _______.A. parents and children should not have a generation gapB. parents should show love and respect to their childrenC. there are some good ways to bridge the generation gapD. there are so many serious problems in families today51.A 52.C 53.A 54.CTom Dyson tried to find out what his new machine could do. One day he put the small box to a flowering plant that was growing in a big pot. He didn’t say anything at a ll, but he began to think something bad about the flowers.“I’m going to cut off these flowers. They’re getting old and no longer beautiful. So I’ll cut them off…”The needle(指针)on the machine climbed quickly from zero to 8, then 10, 12, 15. It stopped at 17. The plant was in trouble! Something was worrying it. Was it afraid or sad? The thought of being cut? The flowers bent(弯下)their heads. They suddenly looked old and tired, and Tom felt sorry for them.“No, no!” he cried. “I won’t cut you. You’re my frien ds. I just want you grow and be more beautiful. I’ll take you outside, into the sunshine. You’ll like that, won’t you?”The flowers raised their heads slowly and seemed to smile at him. The needle returned to zero. Tom put away the machine, picked up the plant and walked outside. It was very nice in the garden that morning.All plants enjoy their owner’s love and kindness. They know the sound of their voice. They also seem to understand people’s thinking. So if you have flowers of your own, think about them with love. They will return your kindness in the only way they can: they will grow strong and beautiful.1. Which is the right order of the things happening in the passage?a.Tom felt sorry for the flowers.b.The needle climbed to 17.c.Tom put a machine to a flower plant.d.The flowers bent their heads.e.Tom thought of cutting off the flowers.A. a, c, e, b, dB. c, e, d, b, aC. a, c, e, d, bD. c, e, b, d, a2. The needle turned back to zero when Tom ________.A. took the flowers into the sunshineB. put away the machineC. said something nice to the flowersD. thought about the flowers3. If you show love to your plants, they will give you their love in return by _______.A. raise their heads and smilingB. growing nice and beautifulC. turning the needle to zeroD. enjoying your kindness4. We can infer from the passage that ________.A. the flowers didn’t like what Tom said and didB. the flowers could understand what Tom was thinking aboutC. the machine didn’t work well and should never be used againD. Tom should go to see and talk to the flowers very oftenDCBBThe children at the top of the class succeed by knowing a few basic skills that others can easily learn. According to the education experts and students themselves, here are the secrets of top students.Study is the first thing. Once the books are open or the computer is on, phone calls are unanswered, TV shows unwatched, snacks unnoticed. Study is business; business comes before everything.Study anywhere or everywhere. Study times are different for different children. Some work late at night when the house is quiet. Others wake early. Still others study as soon as they come home from school. However, all agree that consistency (持之以恒) is needed.Get organized. Don’t waste time looking fo r a pencil or missing paper. Keep everything right where one can put one’s hands on it. Even for a student who doesn’t keep his own study area organized, a bag or a drawer is needed to put things in to save time.Learn how to read. The secret of good reading is to be an active reader—one who continually asks questions that lead to a full understanding of the writer’s message.Use your time best. Even the best students put off their work sometimes. But when that happens, they face it. “If you want to be at the top, make sure to finish the work on time.” says Christi Anderson, a top student at Lyman High School.Take good notes and use them. Reading the text is important, but the teacher is going to test you on what he or she emphasized (强调). That’s what you find in your notes.Another kind of important “secret” of the top students is not so secret at all. For almost all of them, their pa rents’ help is important.34. According to the third paragraph, as students, we should all .A. study late into nightB. study in the early morningC. study as soon as we get homeD. study in our favorite time with consistency35. The fourth paragraph mainly tells us to save time for study.A. to look for our stationeryB. to keep everything in handC. to get everything organizedD. to organize ourselves into groups36. Which of the following is true about an active reader?A. Take good notes.B. Ask questions continually.C. Study everywhere.D. Arrange time well.37. According to the writer, the real secret in becoming a top student lies in .A. the good teachersB. the good education expertsC. some basic learning skillsD. the parents’ helpDCBCToday, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle was invented in Germany in 1818. Because it was made of wood, it wasn’t very strong nor did it have pedals (脚踏板).Riders moved it by pushing their feet against the ground.In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan’s machine had iron-covered wheels to keep them from getting worn down. He also used foot-operated levers, similar to pedals, so his bicycle could be ridden at a quick pace. It didn’t look much like the modem bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan’s bicycles could be ridden easily, they were never produced in large numbers.In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved pedal mechanism. They called their bicycle a VELOCIPEDE,but most people called it a “bone shaker” because of the effect of the wood and iron frame. Despite the impolite nickname, the VELOCIPEDE was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people.Ten years later, James Starley , an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient,and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy,and ridden mostly for entertainment.It wasn’t until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today’s cyclists. The safety bicycle had equal-sized wheels, which made it easier to ride. Lawson also attached a chain to the pedals to drive the back wheel. By 1893,the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson; bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world.31.This passage was most likely written in order to _____.A. compare bicycles used for different purposesB. describe the problems early bicycle makers experiencedC. persuade readers to use bicycles for transportationD. tell readers about the early history of the bicycle32.Macmillan covered the wheels of his bicycle with iron to _____A. add weight to the bicycleB.make the bicycle easier to rideC. allow the wheels to last longerD. let the bicycle be more comfortable33. Which of the following bicycle types was invented by James Starley?34 Which of the following statements is true according to the passage?A. Two hundred years ago,bicycles did not exist.B. The first bicycle could be ridden at a very quick pace.C. The Michaux brothers called their bicy cle a “bone shaker”.D. Macmillan’s machine had wheels with rubber tires.35.The information about bicycles in this passage is arranged according to _____.A. importanceB. timeC. placeD. interest DCBAB。
