七年级数学下期末质量检测试卷分析

郝鹏鸽

一、试卷结构分析

试题紧扣教材，体现了新课标的理念和基本要求，尤其在过程与方法上考查的力度较大。对于基础知识和基本技能也有足够的题量，题型适当，难易适中。本套试卷满分100分，考试时间90分钟。试题分选择题、填空题、解答题三部分。

二、试卷特点评析：

从试卷卷面情况来看，考查的知识面较广，类型比较多样灵活，同时紧扣课本、贴近生活。既考查了学生对基础知识把握的程度，又考查了学生的实际应用、计算、思维以及解决问题的能力，不仅顾及了各个层次学生的水平，又有所侧重。这对当前初中数学教学有很好的指导意义。重视了数学思想的普查，体现了学生实践能力的考查，让学生解决自己身边的实际问题，体现知识的价值，激发学习的热情。

三、答题中存在的问题：

从答题情况看，大部分学生能较好地掌握初中数学的基础知识和基本技能，学生答题中不乏简捷和富有个性的解法，但仍有不少学生对双基把握不透，运算正确性差。存在的重要问题如下：

1、学生对基本概念把握不清，理解不透，如对平移概念、绝对值的理解、数轴的三要素、组距和组数定义等。主要表现在∣1-√3∣计算时，去掉绝对值符号，出现的问题较多、做数轴时，没有箭头或原点。

2、不能正确理解字母与数字的关系。例如第14题，得分较低，本题应将字母k在解题中看做常量，解一元一次方程，最后根据题目要求转化为关于k的不等式，从而求得k的取值范围。

3、学生解题运算能力较差。数学不仅仅考察学生的思维能力，更重要的试训学生的解题运算能力，这在每年的数学试题考察中都有体现。通过近年来的考试阅卷分析，学生的运算能力普遍较弱，今后在教学中应该重点加强。今年主要表现在不等式的解法，学生出现的问题较大，如移项忘记变号、漏项、加减运算错误等。

4、书写不规范，推理不严谨。主要表现在19题的证明题中。学生在证明过程中，原因和结论混乱，“所因非所论”证明过程逻辑推理能力较差。

5、书写潦草，卷面乱写乱涂，解题过程不完整，不规范，随心所欲。

三、今后教学建议

1、重视概念、公式定理的教学，提高学生的计算能力。课堂教学中板书不可忽视，让学生不仅听懂，而且会规范的书写。

2、加强基础知识的教学，重视双基，平时的教学要进一步体现面向全体学生的原则。尽量提高课堂的趣味性,使学生能融于课堂。加强综合题的训练，提高学生的创新能力和应变能力。

3、夯实基础，努力实现课标的基本要求。要切实抓好基本概念及其性质、基本技能和基本思想方法的教学，让学生在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能、数学思想和方法，并形成合理的知识网络结构。不能脱离课标、教材大搞“题海战术”。

4、加强数学思想方法的教学。数学思想方法的教学应渗透在教学全过程中，使学生不仅学好概念、定理、法则等内容，而且能体会数学知识的发生、发展，把握蕴含其中的数学思想方法，并通过不断积累，逐渐内化为自己的经验，形成解决问题的自觉意识。

5、面向全体，加强学法指导，在教学中面向全体学生，鼓励学生自主探索和合作交流，促使学生将知识构成网络、形成系统。努力实现不同层次的学生都得到发展。

6、掌握命题的基本原则。(1)考查学生的基本运算能力、思维能力和空间观念的同时，着重考查学生运用数学知识分析和解决实际问题的能力。(2)试题立意，以“两个意识”(创新意识、应用意识)和“四种能力”(运算能力、空间想象能力、逻辑思维能力和应用数学知识解决简单实际问题的能力)并举立意，试题要体现出数学的教育价值。因此，我们在平时的教学中要在这些方面下工夫。

7、加强对学生思想、意志和心理素质等“非智力因素”的指导与训练，培养学生良好的书写习惯(解题周密、严谨、书写规范、简练)，减少过失性的失分。

Mr.Hill was sitting and enjoying the sun in his garden(花园).He waved,and Mariko waved back.

“Mr.Hill loves his garden,”said Mariko.Mr.Hill had the most beautiful spring fl ower garden.It was full of daffodils(黄水仙).

Dad said,“Yes,he does.And because he is old,it is hard for him to go outside in winter.”

At the store,Mariko helped Dad choose milk,bread and carrots.

“You may choose something for yourself,Mariko,”said Dad.

At first Mariko thought apples would taste good.But then something else caught her eye,“Oh,Dad,look,daffodils!”

“Is that something you want?”asked Dad.

“Yes!”Mariko said happily.

Mariko couldn’t stop looking at her daffodils all the way home.But when she got to Mr.Hill’s house,she stopped,“Maybe I could...”

“Wait here,Dad,please,”she said.“I’ll be right back.”

Dear Tommy,

I’m in Paris now!Mom,Sally and I came here to visit my uncle.We are having a wonderful time.Dad didn’t come because his company(公司)sent him to work in Japan last month.He will have to stay there until November.

For Sally and me,it’s our first time to come to France.We are so excited!Last week Mom went to different shows alone.She used to study in Paris,so she knows the city well.Sally and I visited many interesting places with Aunt Susan.Although we can’t speak French,it’s OK.Aunt Susan and Uncle Tyler can speak both French and English.

Yesterday afternoon,Mom,Sally and Aunt Susan stayed home cooking dinner.Uncle Tyler took me fi shing.We drove for an hour and fi nally arrived at his favorite lake.First,we walked around the lake looking for a good place to fi sh.Uncle Tyler said we should fi sh from the top of a large rock.

I was so interested in catching a fi sh that when I threw my fi shing line and hook(鱼钩)out,the rod(鱼竿)went with them!Uncle Tyler got my rod out of the lake.Then he said that next time,I should wait until he put bait(鱼饵)on the hook.

We fi shed for two hours and my uncle caught four fi sh.He is a fantastic fi sherman.The only thing I caught was a cold.I can’t wait to go again soon,so I can become a great fi sherman like him.

Yours,

Frank

On Thursday a new boy came into the classroom.He didn’t have any uniform on.Just trousers,a jacket and a shirt.Tom could see that the boy wasn’t quite comfortable.He had a plastic(塑料的)bag with exercise books,pens,pencils,rulers and erasers in it.The boy stood at the blackboard.Miss Fair talked to the boy,and then she said,“Boys and girls,this is Peter Rivers.He is your new classmate.Peter is your age.I hope you’ll get on well with each other.Peter will spend a lot of time together with you,and outdoors too.”Miss Fair asked Peter to sit next to Tom at the desk near the window.

The students had math after that and Tom could see that Peter was not bad at it.He counted(数数)well.It was not diffi cult for him at all.Then Miss Fair said,“It is half past twelve.It’s time to have lunch.”Peter joined Tom and went to wash his hands.Then the boys sat down on the fl oor and started to open their lunch bags.Tom opened his bag and put his hand in it.He took out an old brown apple,some old cheese and some bits of fi sh from dinner.“Oh,no!”cried Tom.“This is rubbish.I have the wrong bag.I took the rubbish bag and left my lunch bag at home.I have only rubbish for lunch today.”The other children laughed and laughed.Then Peter said,“I have two eggs.Why don’t you have one?I don’t need two.And would you like some bread?”Tom smiled,“Thanks.Now I’ll always look in my lunch bag before I bring it to school.”

4 千米/时答：他从休息后直至到达目的地这段时间的平均速度是4千米/时。

27、（1）.①因为△BPD与△CQP全等，即DB=PC,而BC=BP+PC,BP=3,DB=1/2AB=9,则BC=9+3=12

.②要使△BPD与△CQP全等，而且点Q的运动速度与点P的运动速度不相等，那么必须点P是BC中点，点Q是AC中点，而BC=9+3=12，所以BP=6，那么时间是6÷3=2

秒，而CQ=12AC=9,所以点Q速度=9÷2=9

（2）两点第一次相遇，可得时间t=（AB+AC）÷（9

2-3），=（18+18）÷（9

-3）=24秒点P的移动路程为：24×3=72cm，72-12-18-18-12=12cm，所以点P经过24秒在边AC上第一次相遇，而且离点C12cm处
