马上要迎来期中考试，而本学期新开科目—化学的考试的题型和重点是很多同学所陌生的，智康1对1化学教师郑楠楠总结教学经验，为同学介绍化学考试的侧重点、题型和复习方法。

Is about to usher in the mid-term examination,But this term new open subject - chemical examination questions and key is many students have strange,Wisdom kang 1 on 1 chemistry teacher ZhengNanNan summarize the teaching experience,For students to introduce the emphasis of the chemistry test/The topic and review the methods.

　　化学试题注重基础知识，侧重对基础知识和基本技能的考查。以能力测试为主导，它会综合考查九年级上册前四单元全部内容。考卷的题数会和中考题接近。共计有35题，其中25道选择题，5道填空，3道实验，2道计算。化学考试的知识涵盖面广，灵活性较强。很多学生会觉得化学不太难，但很难拿高分，这时细心和用心就成为拿高分的关键。

Chemistry questions to pay attention to the basic knowledge,Focus on the elementary knowledge and the basic skill examination.With ability test as the leading factor,It will be comprehensive test taken nine grade four unit full content.The examination question number will and the examination questions close to.A total of 35 problem,Among them 25 way choice,5 ways fill in the blanks,Three way experiment,2 way calculation.The chemistry test knowledge covers a range widely,Flexibility strong.Many students think chemistry is not too difficult,But it is difficult to get high scores,Then carefully and attentively becomes the key to get high marks.

　1、注重对基础知识的学习 1/Pays great attention to the basic knowledge of learning

　　化学试卷知识点较多，大部分试题源于教材。在教材的基础上增加了灵活性，它会注重考查化学知识的实用性。这会在选择题和填空题中明显体现。

Chemistry examination paper more knowledge,Most of the questions from textbooks.On the basis of teaching material increases the flexibility,It will pay attention to test the practicality of chemical knowledge.This will in the choice and fills up the topic obviously reflect.

2、注重化学概念理解性及本质问题 2/Pay attention to chemical concept comprehension and nature of the problem

　　化学试题在考查理解能力的同时对知识的延展性也要求较高，这需要同学们了解每个概念的由来和化学现象的本质。大家要多问为什么，增加知识储备，这对我们分析"拔高题"大有好处。

Chemical test examines the ability of understanding and knowledge of the ductility and the demand is higher,This requires the students to understand the origin of each concept and the nature of chemical phenomena.Everybody to want to ask why,Increase knowledge reserve,This to our analysis"Above problem"good.

　3、注重化学用语 3/Pay attention to chemical language

　　化学用语是化学学科的"语言"，是学生学习化学的基础。也是培养学生化学素养的关键环节。本次期中考试会在我们现学的元素符号、分子式、化合价和离子符号等化学语言上出题。常出现的是图型题，大家做题的时候要细心，小心陷阱。

Chemical term is chemistry discipline"language",Is the basis of students' learning chemistry.Is to cultivate students' chemical literacy key link.The mid-term examination will be in we are now learning symbol of element/Molecular formula/Valence and ion symbol set chemical language.Often appear of the problem is the pattern,Everyone do the topic the time to carefully,Be careful trap.

　　例如：把一定质量的纯净物A和80 g B在一定条件下按下图所示充分反应，当B消耗完时，可生成88 g D物质和18 g E物质。

For example:Put A certain quality of pure substance A and 80 g B under certain conditions according to that shown in the photo below fully reaction,When B consumption when they finish the,Can generate 88 g D material and 18 g E material.

　　请回答参加反应的A物质的质量是？      

Please answer to reaction of A material quality is?      

　　注意：我们要看清是求"参加反应的A物质的质量"，还是要求"A的相对分子质量"

note:We want to see is to ask for"In response the quality of A material",Or requirements"A relative molecular mass"

4、实验题的考查 4/Experimental subject examination

　　实验是化学学习的基础，实验题分值占整个化学分值的四分之一。该题型主要注重，对药品和实验仪器的选择、反应原理、实验操作和实验操作不当引起的误差、实验注意事项、实验现象叙述、对比实验的优缺点等考查。这部分的复习要回归课本，一定要吃透课本上的知识，考试的题型会根据课本知识灵活出题。这就要求我们对课本上每个基础实验要研究透每个细节，达到举一反三的程度。探究实验是实验题中的难题，做这部分题的时候要看好"探究目的"和"资料信息"，要抓住资料信息的重点，一定要保证所有的操作都围绕探究目的进行。

Experiment is the basis of the chemistry learning,The problem of the total score with a quarter of the chemical score.This topic mainly pay attention to,For drugs and experimental apparatus choice/Reaction principle/Experimental operation and experiment the error caused by improper operation/Experimental matters needing attention/The experiment phenomenon narrative/Comparative experiments, such as the advantages and disadvantages of examination.This part of the review to regression textbooks,Must have a thorough grasp of textbook knowledge,Exam questions will be according to the textbook knowledge on flexible.This requests us to textbook each experiment to research through every detail,To the extent of the other.Inquiry experiment is the experimental subject problem,Do this part problem be valued"Inquiry purpose"and"Material information",To seize the key information,Must ensure that all operations are about the aims to explore.

5、化学计算 5/Chemical calculation

　　期中考试的计算注重于考查学生的分析能力和答题规范，立足于化学式的基本计算，难度不大。学生注意计算和规范答题，不会有太大的失分。

Mid-term exam calculation pay attention to test students' analysis ability and the answer specification,Based on the chemical formula the basic calculation,Difficulty is not great.Students pay attention to calculation and standardize the answer,Won't have too big points.

　　综上所述：我们要学好化学并要取得好成绩就要做到回归课本，扎实基础，注重细节，规范语言，理解原理，获取和分析信息。

To sum up:We must learn chemistry and want to get good grades will do regression textbooks,Solid foundation,Attention to detail,Specification language,Understand principle,Obtain and analyze the information.
