夯实基础培养能力强化训练巩固提高

夯实基础培养能力强化训练巩固提高作者：张伟来源：《中学生英语·教师版》2017年第02期在一轮复习中我们树立“面向全体，略有侧重”的教学思想，我们把这一轮次的复习教学分两个阶段进行：第一阶段主要任务是利用假期泛学第九、第十册教材，在学习过程中，我们充分利用了这两个模块中的话题和阅读材料，重点扩展词汇和培养学生阅读、理解较难文字材料的能力和思维能力，掌握不同文体的特征和阅读技巧，带动基础知识的复习巩固。

第二阶段主要任务是系统复习1～8册教材，按《考纲》要求，面向全体学生，夯实基础，进行系统复习。

复习的基本要求如下：1. 加强研究，做到复习上的有的放矢首先要认真学习和研究《课程标准》和《考试说明》，准确把握复习方向，提高复习的针对性，这样就可以做到复习有章可循，有的放矢。

其次根据学生的实际，确定教学的重点、难点。

2. 夯实基础，构建牢固的知识体系2.1词汇复习词汇量不足是历届考生共同面临的一大问题。

现在的高考阅读就是以3000个至3500个词汇量为标准的，这就需要我们以课本为依据扩大学生的词汇量。

扩大词汇量最有效的方法—是构词法，一是大量阅读。

应在阅读中识记新的词汇，在阅读中观察词汇的用法。

同时可以通过阅读培养推测生词词义的能力。

这样既扩大了词汇，又提高了阅读能力。

有了词汇，具备了较高的阅读能力，就具备了较强的做完型填空、阅读表达和写作的能力。

2.2习题巩固这个环节主要是对资料上的习题选择性的挑选训练和讲评。

注意例题选用，要精选典型习题。

典型例题重点讲解，培养学生理解策略的转换能力。

选取例题要遵循两个原则：一是有利于解题策略转换，训练学生的多方位的思维方式；二是有利于变式学习，训练学生思维的灵活性，敏捷性，深刻性。

2.3加强阅读理解阅读能力的考查一直是高考英语测试的重点，如果再加上完型填空、阅读表达的话，考查阅读理解能力的试题正好是全卷的一半。

是名副其实的重头戏。

通过阅读理解训练，学生可以巩固和加强各项英语基础知识，又可以学到许多英语表达的方法和技巧，这些东西又成了书面表达的基础。

巩固期训练计划

巩固期训练计划一、背景介绍在学习中，巩固期是一个非常关键的阶段，它决定了学习成果的保持和进一步提高的能力。

为了帮助学生有效巩固所学知识，并取得更好的学习成果，我们设计了一套巩固期训练计划。

二、训练目标1. 帮助学生巩固所学的基础知识和技能；2. 提高学生运用所学知识的能力；3. 培养学生的学习兴趣和学习习惯。

三、训练内容1. 复习基础知识：通过复习基础知识，巩固学生的知识储备。

可以采用课堂小测验、练习题等形式进行。

2. 解决难点问题：着重解决学生在学习中遇到的难点问题，通过针对性的辅导和练习，帮助学生克服困难。

3. 拓展应用能力：通过一些综合性的应用题，让学生学会将所学知识应用到实际问题中，培养学生的综合应用能力和创新思维能力。

4. 强化训练：通过大量的习题训练和模拟考试，提高学生的解题速度和准确性。

四、训练方法1. 讲授与实践相结合：在训练过程中，既要进行知识点的讲授，又要进行实际操作和练习，让学生在实践中巩固所学知识。

2. 个性化辅导：根据学生的不同情况和需求，采取个性化辅导，帮助学生解决具体问题。

3. 组织合作学习：通过小组合作学习的方式，促进学生之间的互动和合作，提高学习效果。

4. 视频教学资源：利用网络资源，提供精选的教学视频，帮助学生更好地理解知识点。

五、训练计划1. 制定个人学习目标：学生根据自己的情况和需求，制定巩固期的学习目标，并与老师进行反馈和讨论。

2. 每日学习计划：根据学习目标，制定每日学习计划，合理安排时间，保证每个知识点都得到充分的复习和训练。

3. 定期小测验：每周进行一次小测验，检测学生对知识的掌握情况，并及时进行补充和巩固。

4. 组织模拟考试：在巩固期末阶段，组织模拟考试，模拟真实考试环境，提高学生的应试能力和抗压能力。

5. 辅导和答疑时间：安排辅导和答疑时间，让学生对学习中的问题进行咨询和解答，及时解决学习困惑。

六、效果评估1. 考试成绩评估：通过巩固期末的考试成绩评估学生的巩固效果。

重视巩固训练提高教学效果

重视巩固训练提高教学效果期中考试结束，我心情愉快地改起试卷来，令人吃惊的是，我发现试卷的最后一题错的特别多，班里的60个学生，有49个都做错了！正确率不足20%。

我清楚地记得，因为要进行期中考试，我特意在考试前重点训练了这种类型，而且采用了画图和列举两种方法，当时感觉同学们也都听懂了，学会了。

为什么会出现现在的这种情况呢？我带着这个困惑参加了年级组进行的集智研讨，资深的老教师陈春梅说：“不管什么样的题目，讲一遍，学生是很难都会的，有的同学不一定理解，有的同学则属于注意力不集中。

这就要求我们在教学中要重视巩固训练……”我在平时的教学中注意到巩固训练的方法很多，我们老师在平时的教学中要重视积累，探索利用不同的方法，进行巩固训练，以提高教学效果。

一、利用共性模仿进行巩固训练，提高教学效果。

小学数学课标指出：“小学生应获得适应社会生活和进一步发展所必需的数学的基础知识、基本技能、基本思想、基本活动经验。

”必要的模仿是培养学生创造能力的前提，在教学中应当培养学生的模仿能力。

当学生直接学到一些解题的方法与技巧，或通过收集各种题型、积累各种解题思路，在脑海中储存了一定的解题方法，也就为将来的创造性思维奠定基础。

如在教授了“8的乘法口诀”后，我出了这样一道题：用“七八五十六”写出四道算式，聪明的同学很快想出了两道乘法算式和两道除法算式，紧接着，我请同学们在1至8的乘法口诀中随便找一句，在同桌之间互相说一说。

我则进行巡视，对说得快的同学加以表扬，并提醒他们，“你们还能再多说几句口诀吗？”那些学生在得到老师的肯定和表扬后，表现的更加积极了，而对那些基础较弱，反应较慢的学生，则鼓励同桌互帮互助，共同进步，通过模仿训练，同学们加深了对知识的理解，在以后遇到同种类型的题目，他们不仅有的放矢，而且很少出错。

试想，如果不对学生进行模仿训练，学生脑中空空，没有基本的活动经验和思想，连基本的解题方法与技巧的“素材”也没有，那又怎么能掌握基础知识，形成基本技能呢？二、利用知识变式进行巩固训练，提高教学效果。

OA＝|2﹣0|+|3﹣0|＝2+3＝5，故答案为：5；（2）∵d AB＝|4﹣2|+|2﹣3|＝2+1＝3，∴2d AB＝6，∵点C在第三象限，∴m＜0，n＜0，d OC＝|m﹣0|+|n﹣0|＝|m|+|n|＝﹣m﹣n＝﹣（m+n），∵d OC＝2d AB，∴﹣（m+n）＝6，即m+n＝﹣6，∴d AC＝|2﹣m|+|3﹣n|＝2﹣m+3﹣n＝5﹣（m+n）＝5+6＝11，d BC＝|4﹣m|+|2﹣m|＝4﹣m+2﹣n＝6﹣（m+n）＝6+6＝12，∵3+11≠12，11+12≠3，12+3≠11，∴△ABC不是为“等距三角形”；（3）点C在x轴上时，点C（m，0），则d AC＝|2﹣m|+3，d BC＝|4﹣m|+2，①当m＜2时，d AC＝2﹣m+3＝5﹣m，d BC＝4﹣m+2＝6﹣m，若△ABC是“等距三角形”，∴5﹣m+6﹣m＝11﹣2m＝3，解得：m＝4（不合题意），又∵5﹣m+3＝8﹣m≠6﹣m，6﹣m+3＝9﹣m≠5﹣m，∴△ABC不是“等距三角形”，∴当m＜2时，△ABC不是“等距三角形”；②当2≤m＜4时，d AC＝m﹣2+3＝m+1，d BC＝4﹣m+2＝6﹣m，若△ABC是“等距三角形”，则m+1+6﹣m＝7≠3；若6﹣m+3＝m+1，解得：m＝4（不合题意）；若m+1+3＝6﹣m，解得：m＝1（不合题意）．∴当2≤m＜4时，△ABC不是“等距三角形”；③当m≥4时，d AC＝m+1，d BC＝m﹣2，若△ABC是“等距三角形”，若m+1+m﹣2＝3，解得：m＝2（不合题意）；m﹣2+3＝m+1恒成立，∴m≥4时，△ABC是“等距三角形”，综上所述：△ABC是“等距三角形”时，m的取值范围为：m≥4．。

Small shops usually close for an hour at lunchtime. One or two days a week--- usually Thursday and / or Friday--- some large food shops stay open until about 8:00 p.m. for late night shopping.Many shops are closed in the afternoon one day a week. The day is usually Wednesday or Thursday and it is a different day in different towns. Nearly all shops are closed on Sundays. Newspaper shops are open in the morning, and sell sweets andcigarettes as well. But not all the things can be sold on Sundays.Usually it is not difficult for foreign visitors to find where to buy things. Most shops sell the things that you want to buy. One problem is stamps. In Britain you can only buy these at post offices. Many large food shops are self-service. When you go into one of these shops, you take a basket and you put the things you wish to buy into this. You pay for everything just before you leave. If anyone tries to take things from a shop without paying they are almost certain to be caught, because most shops have detectives.When you are waiting to be served in a shop, it is important not to try to be served before people who arrive before you. Many foreign people are surprised at the British way of queuing.44. According to the passage, which of the following sentences is NOT true?A. Some large food shops open for about 11 hours on Thursday or Friday.B. Many shops are closed in the afternoon once a week on Tuesday.C. Only a few things can be bought on Sundays.D.

I am sure you have often asked these questions. They are very difficult to answer, aren‟t they?If someone asks you: “What color is the sky?” I think maybe you will answer “Blue”.I am afraid you are wrong. The sky has no colors. When we see blue, it is the sunlight that is shining on little bits of dust in the air.Is the sky full of air? I am sure you have asked this question, too. We know that there is air all around the earth. Planes can‟t fly without air. They need air to lift their wings. Planes can‟t fly very high because as they go higher, the air gets thinner. If we go toohigh up in the sky, we find there is no air.Perhaps you can answer some of the questions now. What is the sky? Nothing. Where is it? It is all around the earth. The sky is a part of space.47. What color is the sky according to the writer?A. Blue.B. White.C. Black.D. Colorless.48. What is in the sky?A. It‟s empty.B. It‟s full of air.C. It has clouds.D.
