Boys and girls will have a nearly two months’ holiday, and they’ll leave school by train or by car to return home to see their fathers and mothers.The summer holiday is the best time of the year for most students. The weather is good, so they can spend most of their time playing outside .If one lives in the country, he can go on a trip into the woods or in the fields. If one lives in a big city, he can go to a park to play.The best place for a summer holiday is the seaside. Some children are lucky enough to live near the sea. But for the others who do not, if they have the chance to stay at one of the big seaside towns for a week or two, they will talk about it all the following school year.Now, what makes children like the seaside so much? I think it is the sand, the sea and the sun, not anything else. Of course, there are lots of new things to see, nice things to eat and interesting things to do.

x的值;(2)若关于y的方程﹣y=2的解是y=m x,求|1﹣2a|考点:项式;解一元一次方程.分析:(1)根据题意知,x3、x的系数为0,由此求得m、n的值.(2)把(1)中的m x的值代入已知方程求得a的值,然后来求|1﹣2a|的值.解答:解:(1)mx3+x3﹣nx+2015x﹣1=(m+1)x3+(2015﹣n)x﹣1.∵代数式mx3+x3﹣nx+2015x﹣1的值与x的取值无关,∴m+1=0,2015﹣n=0,解得 m=﹣1,n=2015.∴m x=1或m x=﹣1;(2)由(1)知,m x=1或m x=﹣1.①当m x=1时,y=1,则﹣1=2,解得 a=3,则|1﹣2a|=|1﹣2×3|=5;当m x=﹣1时,y=﹣1,则+1=2,解得 a=7,则|1﹣2a|=|1﹣2×7|=13;综上所,|1﹣2a|=5或|1﹣2a|=13.点评:本题考查了多项式,先合并同类项,再根据x3、x的系数都为零得出方程.25.(2014秋•腾冲县校级期末)已知:A=2x2+3xy﹣2x﹣1,B=﹣x2+xy﹣1.若3A+6B的值与x的值无关,求y的值.考点:整式的加减.分析:先求出3A+6B的结果,然后根据3A+6B的值与x的值无关,可知x的系数为0,据此求出y的值.解答:解:3A+6B=3(2x2+3xy﹣2x﹣1)+6(﹣x2+xy﹣1)=(15y﹣6)x﹣9,∵3A+6B的值与x的值无关,∴15y﹣6=0,解得:y=.点评:本题考查了整式的加减,解答本题的关键是掌握去括号法则和合并同类项法则.26.(2014•咸阳模拟)已知A=5a+3b,B=3a2﹣2a2b,C=a2+7a2b﹣2,当a=1,b=2时,求A﹣2B+3C的值.考点:整式的加减.分析:先把A、B、C代入,再进行化简,最后代入求出即可.解答:解:∵A=5a+3b,B=3a2﹣2a2b,C=a2+7a2b﹣2,∴A﹣2B+3C=(5a+3b)﹣2(3a2﹣2a2b)+3(a2+7a2b﹣2)=5a+3b﹣6a2+4a2b+3a2+21a2b﹣6=﹣3a2+25a2b+5a+3b﹣6,当a=1,b=2时,原式=﹣3×12+25×12×2+5×1+3×2﹣6=52.点评:本题考查了整式的化简求值和有理数的混合运算的应用,主要考查学生的计算能力和化简能力.。

My parents gave me both of my other names. People don’t use their middle names much. So “John Henry Brown” is usually called “John Brown”. They use Mr, Mrs or Miss with the family name but never with the first name. So you can say John Brown, or Mr Brown; but you should never say Mr. John.Sometimes people ask me about my name. “Why do your parents call you Jim?”they ask. “Why do they choose(挑选) that name?” The answer is that they don’t call me Jim. They call me James. James is the name of my grandfather. In England, people usually call me Jim for short. That’s because it is shorter and easier than James.( )6. Most English people have ______ names. A. one B. two C. three D. four( )7. _______ is Jim’s family name. A. Jim B. Green C. Allan D. James( )8.

2015届高考化学一轮复习单元测试: 电化学基础(人教版)
2015届高考化学一轮复习单元测试:电化学基础(人教版)第I卷(选择题)一、选择题1.在用Zn片、Cu片和稀硫酸组成的原电池装置中,工作一段时间后,下列说法正确的是A.锌片是正极,铜片上有气泡产生 B.电流方向是从锌片流向铜片C.溶液中硫酸的物质的量浓度减小 D.电解质溶液的pH保持不变【答案】C【解析】试题分析:原电池中较活泼的金属是负极,失去电子,发生氧化反应。
电子经导线传递到正极,所以溶液中的阳离子向正极移动,正极得到电子,发生还原反应。
锌比铜活泼,所以锌是负极,失去电子。
铜是正极,溶液中的氢离子在正极得到电子生成氢气。
A不正确,BB 正确,电流方向是从铜片流向锌片,C正确,D不正确,氢离子浓度降低,电解质溶液的pH 增大,答案选C。
考点:考查原电池的有关判断和应用点评:该题是高考中的常见考点,侧重对学生基础知识的巩固和训练。
有利于培养学生的逻辑推理能力和规范答题能力。
明确原电池的工作原理、构成条件是答题的关键,注意相关知识的积累和总结。
2.根据下图,判断下列说法中错误的是()A.导线上电子由Ag极流向石墨极B.负极电极反应式:Fe3+ + e-=Fe2+C.盐桥中阴离子移向AgNO3溶液D.总反应为:Fe3+ + Ag=Fe2+ + Ag+【答案】B【解析】试题分析:该装置为原电池,其电池的总反应式为Fe3+ + Ag=Fe2+ + Ag+,其负极的反应为Ag-e-=Ag+,正极发生的反应为Fe3+ + e-=Fe2+;该电池中,导线上电子由Ag极流向石墨极,电流为由石墨经导线流向Ag极,故A正确;负极电极反应式:Ag-e-=Ag+,故B错误,为本题的答案;盐桥中阴离子移向AgNO3溶液,故C正确;总反应为:Fe3++ Ag=Fe2++ Ag+,故D正确。
考点:原电池点评:本题考查了原电池的基础知识,该考点是高考考查的重点和难度,本题比较容易,注意本题选择的是错误的一项。
【答案】D【解析】放电时Na 为活泼金属作负极,发生氧化反应;充电时,阳极应为S ,使S X 2-失电子重新变为S 。

I’m very glad to tell you something about how I study English.First, I think an interest in English is very important. When I was in Grade One, we had a new subject –English. It was fresh for me . I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! After that, I learned English harder and harder. Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!Second, I think English is a foreign language. I should learn it well in the following ways: Listen to the teacher carefully, speak bravely, read aloud and have a good vocabulary(词汇). Then practice again and again, never be tired. And I also have a good habit: Asking whenever(不论何时)I have a question, I must make it clear by asking our English teacher. How happy I am when I understand! Beside s this, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also useful. They help me understand a lot of things. So to do more reading is an important way to learn English well.And I also do some exercises from our class magazines, and I often write English diaries. English has become a close friend of mine.Now I have learned English for more than two years. I always keep the first position in our school. From these words, I hope every student can learn English well.1. Why do some students often “have a headache”?A. Because they are easy to catch cold.B. Because it’s often very coldC. Because they think English is easy.D. Because they don’t thin k English is easy.2. The writer tells us that we should be____in English if we want to learn it well.A. interestB. interestedC. interestingD. strict3 The sentence “I got a very good mark” means ______.A.I got a good way.B. I had a good idea.C. I did badly in the exam .D. I did well in the exam.4. The writer thinks English is interesting because________.A. English is full of stories.B. English is full of jokes.C. his teacher often teaches them nice English songs.D. of nothing5. Which of the following is not the way the writer studies by?A. speaking bravelyB. Writing to foreign friendsC. Reading aloudD. Writing English diariesBCan you swim? Do you like swimming? Yes? Well, how can you learn to swim? I think the best way is to go into the water and learn. I’m afraid you’ll never learn to swim just by reading books about swimmi ng or looking at others swimming. It’s the same with the English study. We must practice, practice and practice.Listening and speaking are very important for beginners. The children in English-speaking countries first listen to others. Then they try to imitate and speak. We can listen to English programs on radio. You may just understa nd a few words. It doesn’t matter. Just be relaxed, try to catch every word. Somebody may be a good listener. But he dare not speak. He’s afraid of making mistakes. You know we sometimes make mistakes when we speak Chinese. Don’t be afraid. We must be brav e. If you really want to learn English well, you must try to speak with everyone so long as he knows English. Whether you know him or not is not important when there’s nobody to talk with, you can talk to yourself in English. It’s interesting and also a go od way to practice your spo ken English. Remember, the more you speak, the fewer mistakes you’ll make.Reading and writing are more important for senior school students. First we must choose the books we’re interested in. A lot of reading will improve your language sense. This is the most important. Keep writing English diaries. We can also write English articles. You may even post them to English magazines. Don’t be afraid of failure. Failure is the mother of success.Easier said than done. Well, let’s do more practice from now on. I’m sure you’ll learn English well in this way.1. You can learn to swim by_______.A. reading books aboutB. looking at others swimmingC. having lessons on itD. going into the river and learning2. We should learn English by _______.A. listening and speakingB. reading and writingC. A and BD. swimming3. What will you do with mistakes when you speak?A. Don’t make mistakes.B. Study hardC.
