Dear editor,
My English teacher is very strict with us. Several days ago, when we were in class, Tom asked me a question. But my English teacher thought we were speaking in class. She asked us to stand at the back of the classroom for a few minutes. This made me feel unfair. After that, I feel nervous in her class, so I don’t like her class. However, I really want to learn English well. What should I do?
Yours,
Mike
Dear Mike,
I am sorry you are having difficulty with your English class. Every teacher wants his or her students to study hard. So I think you should have a talk with your English teacher and tell her what you were doing with Tom that day. If she knows your worries, maybe she will help you with your English. And she will be pleased to hear you want to learn English well. Of course, you should know that what your teacher did was good for you. When you are not trying as hard as you can, she has to stop it and try to help you. Wish you have a better life!
Yours,
Editor

四川省遂宁市2016年中考物理试卷
一、单项选择题（本题共10题，共30分，每小题3分；在每小题提供的四个选项中，只有一项符合题目的要求）
1．（3分）（2016•遂宁）关于能源与可持续发展，下列认识正确的是（ ） A．能量在转化或转移的过程中，总量不变
B．太阳能电池是将太阳能转化为内能的装置
C．天然
气是一种清洁能源，人类可以无尽地开发利用
D．核燃料是可再生能源
【分析】（1）能量守恒定律：能既不会消灭，也不会创生，它只会从一种形式转化为另一
种形式，或者从一个物体转移到另一个物体上，在转移和转化过程中，能的总量保持不变；
（2）太阳能电池可将太阳能转化为电能；
（3）天然气属化石能源的范畴，是不可再生的；
（4）核燃料是地球上的储量是有限的．
【解答】解：A、根据能量守恒定律可知，能量在转化或转移的过程中，总量是不变的，故A正确；
B、太阳能电池是将太阳能转化为电能的装置，而不是转化为内能，故B错误； C、天然气是一种化石能源，在地球上的储量是有限的，人类不可能无尽地开发利用，故C错误；
D、核燃料是地球上的储量是有限的，属不可再生能源，故D错误．
故选A．
【点评】本题主要考查了对能量守恒观点的认识，以及对太阳能、天然气、核能等常见能源的特点的了解，属基础知识的考查．
2． （3分）（2016•遂宁）光给人类带来了光明．下列关于光现象的描述中，错误的是（ ）A．“潭清疑水浅”是由于光的折射产生的一种现象
B．三月桃花盛开，游人能观赏到美丽的桃花，是光在桃花表面发生镜面反射的结果 C．雨过天晴后，天空中出现彩虹是光的色散现象
D．人们常说的“天狗吃月”这一现象是由于光的直线传播形成的
【分析】（1）当光从一种介质斜射入另一种介质时，传播方向的会偏折，发生折射现象，如：看水里的鱼比实际位置浅、彩虹等；
（2）表面光滑的反射是镜面反射，它可以把平行光沿特定的方向反射出去，如果人眼接收到反射光感觉很强；
表面粗糙的反射是漫反射，它可以把平行光向各个方向反射出去，人在各个角度都能接收到反射光线，而且接收的反射光不太强；
（3）光的折射现象．由物体发出的光透过不同介质时，会发生折射，使光路发生改变，因此我们看到的是物体的虚像；
（4）在日常生活中，激光准直、小孔成像和影子的形成等都表明光在同一种均匀介质中是沿直线传播的．
【解答】解：A、“潭清疑水浅”是由于光的折射产生的一种现象，故A正确；
B、三月桃花盛开，游人能观赏到美丽的桃花，是光在桃花表面发生漫反射的结果，故B错误；
C、雨过天晴时，常在天空出现彩虹，这是太阳光通过悬浮在空气中细小的水珠折射而成的，白光经水珠折射以后，分成各种彩色光，这种现象叫做光的色散现象．故C正确； D、天狗吃月，即为月食现象，是光沿直线传播形成的，故D正确．
故选B．
【点评】光的直线传播是光在同一均匀介质中的传播，光的反射是光照射到物体表面又返回的现象，光的折射是由于光从一种介质斜射入另一种介质或在不均匀介质中传播时，传播方向发生变化的现象．它们之间有本质的区别，要注意区分．
3．（3分）（2016•遂宁）夏季的清晨，站在涪江边会看到江面上飘着淡淡的白雾，如图所示，这些“白雾”的形成对应的物态变化是（ ）
A．液化 B．汽化 C．升华 D．凝华
【分析】液化使物质由气态变为液态，淡淡的白雾是液态的小水珠．
【解答】解：淡淡的白雾是液化现象，因为河水蒸发产生大量的水蒸气，水蒸气遇到冷空气后液化成小水珠，形成白雾．
故选A．
【点评】对于常见的物理现象，涉及到的物态变化可以对比记忆，例如雨、雪、雾、雹等的形成过程．
4．（3分）（2016•遂宁）下列说法中正确的是（ ）
A．沿海地区昼夜温差比内陆地区小，是由于水的比热容比干泥土的比热容小
B．汽车发动机工作时提供动力的是压缩冲程
C．清洁扫除看到尘土飞扬，可以说明分子在不停地做无规则运动
D．液体在沸腾过程中，吸收热量，内能增加，温度保持沸点不变
【分析】（1）水的比热容较大，同样受热或冷却的情况下，吸收或放出相同热量，但水的温度变化比干泥土等小．
（2）汽车发动机的做功冲程中将内能转化为机械能，为汽车提供动力；
（3）分子是极小的粒子，是肉眼观察不到的；
（4）液体在沸腾过程中，吸收热量，内能增加，温度不变．
【解答】解：A、沿海地区昼夜温差比内陆地区小，是由于水的比热容比干泥土的比热容大，同样受热或冷却的情况下，吸收或放出相同热量，水的温度变化较小，故A错误； B、汽车发动机工作时提供动力的是做功冲程，这一冲程中，将内能转化为机械能，为汽车提供动力，故B错误；
C、清洁扫除看到尘土飞扬，是固体小颗粒的运动，不能说明分子在不停地做无规则运动，故C错误；
D、根据液体沸腾的特点可知，液体在沸腾过程中，吸收热量，内能增加，温度保持沸点不变，故D正确．
故选D．
【点评】本题综合考查了水的比热容的特点的理解，热机的冲程的应用，分子热运动的辨别，以及沸腾特点的认识等，综合性强，但都是基础知识．
5． （3分）（2016•遂宁）如图是滑雪运动员从山上滑下的情景，下列说法中正确的是（ ）
A．运动员下滑过程中，他受到的重力与滑雪板对他的支持力是一对平衡力
B．运动员下滑过程中，若他受到的一切外力都消失，他将处于静止状态
C．运动员加速下滑过程中动能增大
D．运动员穿上滑雪板，增大了与雪地的接触面积，从而增大了对雪地的压强
【分析】（1）平衡力的条件：大小相等、方向相反、作用在同一个物体上，作用在同一条直线上．
（2）一切物体在不受外力作用时，总保持静止或匀速直线运动状态．
（3）动能大小的影响因素：质量、速度．质量越大，速度越大，动能越大．
（4）减小压强的方法：是在压力一定时，通过增大受力面积来减小压强；是在受力面积一定时，通过减小压力来减小压强．
【解答】解：
A、运动员下滑过程中，他受到的重力与滑雪板对他的支持力不作用在同一条直线上，大小也不相等，不是平衡力．故A错误；
B、运动员下滑过程中，若一切外力都消失，它将做匀速直线运动，故B错误； C、运动员加速下滑过程中，质量不变，速度变大，所以动能增大，故C正确； D、运动员穿上滑雪板，对雪地的压力不变，因增大了与雪地的接触面积，从而减小了对雪地的压强；故D错误．
故选C．
【点评】本题考查了动能、牛顿第一定律、摩擦力和重力的认识和理解，是一道综合性较强的题目，但总体难度不大，关键是掌握这些基础知识．
6．（3分）（2016•遂宁）如图所示，作用在杠杆一端且始终与杠杆垂直的力F，将杠杆缓慢地由位置A拉至位置B，在这个过程中，力F的大小将（ ）
A．不变 B．变小 C．变大 D．先变大后变小
【分析】解答此题，首先要判断杠杆的五要素中，有哪些要素发生了变化，然后再利用杠杆的平衡条件进行分析．
【解答】解：在杠杆缓慢由A到B的过程中，动力臂OA的长度没有变化，阻力G的大小没有变化，而阻力臂L却逐渐增大；
由杠杆的平衡条件知：F•OA=G•L，当OA、G不变时，L越大，那么F越大； 因此拉力F在这个过程中逐渐变大．
故选C．
【点评】在分析杠杆的动态平衡时，一般是动中取静，依据杠杆的平衡条件进行分析，最后得到结论．
7．（3分）（2016•遂宁）关于家庭电路及安全用电，下列说法正确的是（ ） A．低于220V的电压对人体都是安全的
B．家庭电路中，控制各个灯具的开关都应安装在相线（火线）上
C．只有当人体接触带电体时才可能发生触电事故
D．教室里一个开关可以同时控制三只日光灯，这三只日光灯一定是串联
【分析】根据对安全电压的了解，家庭电路连接特点和认识，以及对触电的类型的认识，可对选项中的描述逐一做出判断．
【解答】解：A、经验表明，只有不高于36V的电压，对人体才是安全的，故A错误； B、家庭电路中，控制各个灯具的开关都应安装在相线（火线）上，这样在断开开关时，用电器才不会带电，更安全，故B正确；
C、人接触低压带电体时，可能会触电，而靠近高压带电体时，也可能会触电，故C错误； D、教室里一个开关可以同时控制三只日光灯，这三只日光灯都可以在额定电压下工作，一只损坏，不影响其它的灯工作，所以是并联的，故D错误．
故选B．

Dear Alfred，
I want to tell you how important your help is to my life.
Growing up, I had people telling me I was too slow, though, with an IQ of 150 at 17, I’m anything but stupid. The fact was that I was found to have ADIID(注意力缺陷多动障碍). Anxious all the time, I was unable to keep focused for more than an hour at a time.
However, when something did interest me, I could become absorbed. In high school, I became curious about the computer, and built my first website. Moreover, I completed the senior course of Computer Basics, plus five relevant pre-college courses.
While I was exploring my curiosity, my disease got worse. I wanted to go to college after high school, but couldn’t.. So, I was killing my time at home until June 2012 when I discovered the online computer courses of your training center.
Since then, I have taken courses like Data Science and Advanced Mathematics. Currently, I’m learning your Probability course. I have hundreds of printer paper, covered in self-written notes
from your video. This has given me a purpose.
Last year, I spent all my time looking for a job where, without dealing with the public, I could work alone, but still have a team to talk to. Luckily, I discovered the job—Data Analyst—this month and have been going full steam ahead. I want to prove that I can teach myself a respectful profession, without going to college, and be just as good as, if not better than, my competitors. Thank you. You’ve given me hope that I can follow my heart. For the first time, I feel good about myself because I’m doing something, not because someone told me I was doing good. I feel whole.
This is why you’re saving my life.
Yours,
Tanis
25. Why didn’t Tanis go to college after high school?
A. She had learned enough about computer science
B. She had more difficulty keeping focused
C. She preferred taking online courses
D. She was too slow to learn
26. AS for the working environment.Tains prefers____.
A .working by herself B. dealing with the public
C. competing against others D. staying with ADHD students
27.Tanis wrote this letter in order to_____.
A. explain why she was interested in the computer
B. share the ideas she had for her profession
C .show how grateful she was to the center
D. describe the courses she had taken so far

A woman was walking her dog along a beach in New Zealand in late June when she saw
something that looked like a white ball in the sand. It turned out to be a young Emperor penguin that was lost. At his age, he should have been close to the Antarctic, swimming for fish and playing on the ice floes(冰川) . But this penguin started swimming north and just kept going.
The penguin attracted a lot of attention in New Zealand. It has been 40 years since an
Emperor penguin was last seen there. Researchers at the Department of Conservation were called in. They decided to watch the penguin closely, but not to disturb it in any way. Many New Zealanders came to Peka Beach to look at the elegant penguin. They were careful to keep their dogs away from it so it wouldn’t be frightened.
The public nicknamed the animal Happy Feet. Researchers started to notice that Happy Feet didn’t seem well. It turns out that he had been eating the sand from the beach, likely thinking it was snow. The public raised more than 11,000 pounds for an operation to get the sand out of his stomach. The operation was a success, and Happy Feet was taken to a zoo in Wellington, NZ. A group of experts met to decide how to help Happy Feet return to the wild.
Last Sunday, they put him on a boat called the Tangaroa, in a specially built ice-filled box and took him out into the Southern Ocean, southeast of New Zealand. There, they released him into the ocean, which is his natural habitat. He took one last look at his human helpers and then dived into the ocean.
“Emperor penguins spend their first five years at sea,” said Peter Simpson of New Zealand’s Department of Conservation. “ What happens now is up to the penguin.”
Happy Feet was fitted with a satellite transmitter(发射机)so they can monitor his progress using the Internet. So far, the trackers shows that he swam northeast for a little while before getting his bearings and heading south.
28. Where is the young penguin supposed to appear?
A．On the sunny beach B．Near the Antarctic.
C．Inside the hole in the ice. D．In the depths of the ocean.
29. How was the penguin treated after he was found in New Zealand?
A. He was sent to the local zoo and attracted much attention.
B. He was protected well and taken good care of .
C. He was taken to the lab by researchers for study.
D. He was disturbed by many curious New Zealanders.
30. The public collected some money to______.
A．get the sand out of the penguin’s belly B．build a home for the penguin
C．do some research on the penguin D．return the penguin to his habitat
31. What happened to the penguin in the end according to the passage?
A．He was put in a specially built ice-filled box on a boat .
B．He was bought to the Southern Ocean and released.
C．He reached his home--The Antarctic.
D．He swam northeast from the the Southern Ocean. .

Many cities around the world today are heavily polluted. Careless methods of production and lack of consumer demand for environment friendly products have contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic and metal container are produced, and these are difficult to get rid of.
However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these, “Will this shampoo damage the environment?” “Can this metal container be reused or can it only be used once?”
A recent study showed that two out of five adults now consider the environment safety of a product before they buy it. This means that companies must now change the way they make and sell their products to make sure that they are “green”, that is, friendly to the environment.
Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarkets’ products carry labels to show that the product is green. Some companies have made producing of clean and safe products their main selling points and emphasize (强调) in their advertising.
The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of “Buy it, use it, throw it away, and forget it.” The public pressure is on, and gradually business is cleaning up its act.
32. It becomes clear from the passage that the driving force (动力) behind the green products is
______.
A. public caring for the environment B. companies’ desire for bigger sales
C. new ways of doing business D. rapid growth of supermarkets
