六、阅读理解(共30分，每小题2分)

Dear Sir,

I am writing to you about my stay at your hotel. My wife and I arrived on Saturday, May 15th and stayed for a week. Though we were treated well and found the service excellent, we think there are one or two things we should bring your attention.

1. We hoped for a nice holiday from our busy work lives, and your ad said “comfortable and quiet”. We want to have a chance to enjoy ourselves. However, we were always waken up by the noise every morning. Is it really necessary for the workers to start their repair work so early?

2. We hoped to swim in your “wonderful pool”. To our disappointment(失望), we found that it was closed for the whole time of our stay.

I hope you do not mind my writing to you about these things, but I would be happy if you could give me some explanation(说明). As I said at the start, it is a pity, and your service is so good in other places.

I hope to hear from you soon.

Yours sincerely

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.

Polluted air from cars, planes and factories is so thick that it is like a quilt(被子) over a city. This kind of quilt is called smog(烟雾). Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away. And they mustn’t blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.

Rules are not enough, every person must help to fight pollution.

5.八年级数学上册期末复习计划 篇五

为了迎接期末质量检测，实现制定的目标和计划，结合本年级学生情况及八年级数学的实际，对期末质量检测复习作以下安排：

一、复习目标

落实知识点，提高学习效率，在复习中做到突出重点，把知识串成线，结成一张张小网，努力做到面向全体学生，照顾到不同层次的学生的学习需要，努力做到扎实有效，避免做无用功。

1.通过单元区块专题训练，让学生体验成功的快乐，激发其学习数学的兴趣；

2.通过综合训练使学生进一步探索知识间的关系，明确内在的联系，培养学生分析问题和解决问题能力，以及计算能力。

二、复习方式

1.总体思想：先分单元专题复习，再综合练习；

2.单元专题复习方法：晚上先做单元试卷，然后白天教师根据试卷反馈讲解，再布置作业查漏补缺；

3.综合练习：教师及时认真批改，讲评时根据学生存在的问题及时辅导，并且给以巩固训练。

在复习基础知识的同时，每两天处理一套卷子，做到及时反馈，及时消化处理，注重通过典型练习题进行复习，使学生对知识的掌握步步深入；加强对综合性习题的讲解，开阔学生的解题思路。

四、复习过程和措施

（一）分单元复习阶段的措施：

1.复习教材中的定义、概念，进行正误辨析，教师引导学生回归书本知识，重视对书本基本知识的整理与再加工；

2.重视知识区块的专题复习，提高学生的分析问题，解决问题的能力；

3.重视应用题复习，题目的出现可以是信息化、图形化方法形式，或联系生活实际为背景出现信息。让学生自主发现问题，解决问题。题目有层次，难度适中，照顾不同学生；

4.要十分注重课本中的“数学活动”，挖掘教材的编写意图，防止命题者以数学活动为载体，编写相关探究题型。

（二）综合测试阶段的注意点

1.认真分析往年的统考试卷，把握命题者的命题思想，重难点，侧重点，基本点；

2.根据历年考试情况，精心汇编一些模拟试卷，教师给学生讲解一些应试技巧，提高应试能力；

3.在每次测试后注重分析讲评，多用激励性语言，不要讽刺、挖苦学生，更不要打击学生的学习积极性。相信每个学生经过自己的努力都能在期末考生中超长的发挥。

总之，在数学期末复习中，我力求做到精选精练，指导方法，双基训练与能力提高并重。争取让学生取得较好的成绩。
