Often in your reading you will come across(遇见)a difficult new word. You may be able to read the word, but, you still do not know what it 75 One way of finding out a word’s meaning is by looking it up in a 76 Another way is to use context(上下文).

Do you get angry when your friends sing loudly while you are trying to work or when your best friend does not wait for you after school?

Cary Egeberg, an American high school teacher, has written a book named My Feelings Are Just Like Wild Animals to help you control your feelings .The book tells how to stay cool when b 82 things happen.

The book says that getting angry only makes problems w 83 It can never make them better. “Getting angry is not a natural way to act,” the book says. “It is just a habit, like smoking.’’The book says you can control you feelings e 84 ---all you have to do is to tell yourself not to be angry.

The book gives many tips to help you if you get angry frequently. Here are the top three:

● Keep a r 85 Every time you get angry, write down why you are angry. Look at it later and you will see you get angry so often.

● Ask your friends to s 86 talking to you when you get angry. Leave you alone. This will teach you not to be angry.

●Do something d 87 When you get angry, walk away from the problem and go somewhere else. Try to laugh.

I recently went to a charity party. At the end of the visit our host told us that the following Monday was his birthday. He asked if, as a gift to him, we would do something kind for someone else on that day. I thought that was a terrible birthday idea!

The following Monday, I saw my neighbor, a new mother, in the garden with her baby, I went outside to say “hello” to her. During the talk, she told me, not in a complaining way but just as a

matter of fact, about the sleeplessness and the challenges to get anything done with a baby followed by. I remembered the charity party host’s request and said, “Hey!Why don’t I watch your baby for an hour! I will just hang out with him here in the back garden and you go in and take an hour to yourself.”

She was so surprised that she almost cried. “Are you serious? Would you be able to do that?”“of course!” I said. “I’d be happy to!” An hour later she came outside with a smile on her face. “I have got so much done!” she told me, and I told her that I had sung every kid’s song I knew and had a good time hanging out with the baby, too. And I was so happy to see her smiling like that.

It was one of the best presents I’ve ever given, and it has given me the desire to ask the same from all my friends this year. I know it will make me feel great to know my friends are out there sharing their wisdom and time with people who can really use it.

上海市2014年初中毕业统一学业考试 数学答案解析 第Ⅰ卷 一、选择题 1.【答案】B B . 【考点】二次根式的乘法运算法则. 2.【答案】C 【解析】科学记数法是将一个数写成10n a ?的形式,其中110a <≤,n 为整数.当原数的绝对值大于等于10时,n 为正整数,n 等于原数的整数位数减1;当原数的绝对值小于1时,几为负整数,n 的绝对值等于原数中左起第一个非零数前零的个数(含整数位上的零).即1060800000000 6.0810=?,故选C . 【考点】科学记数法. 3.【答案】C 【解析】抛物线2y x =的顶点坐标为(0,0),把点(0,0)向右平移1个单位得到顶点的坐标为(1,0),所以所 得的抛物线的表达式为2 (1)y x =-,故选C . 【考点】二次函数图像的平移 4.【答案】D 【解析】根据同位角的定义:两条直线被第三条直线所截形成的角中,若两个角都在两直线的同侧,并且在第三条直线(截线)的同旁,则这样一对角叫做同位角,可得1∠的同位角是5∠,故选D . 【考点】同位角的识别. 5.【答案】A 【解析】把数据按从小到大的顺序排列,位于最中间的一个数或两个数的平均数为中位数;众数是一组数据中出现次数最多的数据,众数可能不止一个.从小到大排列此数据为37,40,40,50,50,50,73,数据50出现次数最多,所以50为众数,处在第4位是中位数50,故选A . 【考点】中位数,众数. 6.【答案】B 【解析】选项A ,∵四边形ABCD 是菱形,∴AB BC AD ==,∵AC BD ≠,∴ABD △与ABC △的周长

不相等,A 错误;选项B ,∵12ABD ABCD S S =棱形△,12 ABC ABCD S S =棱形△,∴ABD △与ABC △的面积相等,B 正确;选项C ,菱形的周长与两条对角线之和不存在固定的数量关系,C 错误;选项D ,菱形的面积等于两条对角线之积的12 ,D 错误,故选B. 【考点】菱形的性质应用. 第Ⅱ卷 二、填空题 7.【答案】2a a + 【解析】利用代数式的乘法运算的法则计算得原式2a a =+,故答案为2a a +. 【考点】代数式的乘法运算. 8.【答案】1x ≠ 【解析】根据分母不等式0得10x -≠,解得1x ≠,故答案为1x ≠. 【考点】函数自变量的取值范围. 9.【答案】34x << 【解析】先求出不等式组中每一个不等式的解集,它们的公共部分就是不等式组的解集.即1228x x ->??,由②得4x <,则不等式组的解集是34x <<,故答案为34x <<. 【考点】解一元一次不等式组. 10.【答案】352 【解析】三月份销售各种水笔的支数比二月份增长了10%,即三月份销售的水笔支数是二月份的()110%+,由此得出三月份销售各种水笔()320110%320 1.1352?+=?=(支),故答案为352. 【考点】解应用题,列出算式解决问题. 11.【答案】1k < 【解析】∵关于x 的方程220x x k -+=(k 为常数)有两个不相等的实数根,∴0?>,即()22410k --??>,解得1k <,∴k 的取值范围为1k <,故答案为1k <. 【考点】一元二次根的判定式. 12.【答案】26 【解析】如图,由题意得斜坡AB 的1:2.4i =,10AE =(米)AE BC ⊥,∵12.4AE i BE = =,∴24BE =(米), ∴在Rt ABE △中,26AB = =(米),故答案为26.

2013上海中考英语作文 【篇一:2013年中考英语作文案例】 how to protect yourself self-protection is a lifelong topic. earthquakes are the most dangerous disasters because they are unpredictable. if you are outside when an earthquake happens, find an open place. apart from tall structures, electric wires can also be dangerous. if you are in a building, hide yourself under a desk or a chair at once. don’t be afraid because the most powerful part of an earthquake lasts for only a minute. as soon as power lessens, rush to the ground carefully. you should never use lifts in this situation. actually the death rate of an earthquake is quite low and it can be still lower if you know the right methods of escaping. i wish that everybody will be safe during earthquakes. 7+8+4 believe it or not, we may confront with many accidents such as natural disaster, electric shock and so on. thus, it’s essential for us to be careful in daily life and calm down when something happens. for example, electricity brings us convenience, but it can also be the killer. we must remember these points to protect ourselves from danger. first, never touch the electrical appliances with wet hands. second, don’t use too much equipment at the same time, this may cause a fire. if we are more careful, we can enjoy more from what the electricity brings us and live a happier life. 8+8+3 self protection is very important in my daily life. it can prevent me from getting hurt. for example, if a fire breaks out in my apartment, i need to calm down and call “119” as soon as possible. if the rescue team can’t arrive in time, it’s w ise to cover my nose and mouth with a piece of wet cloth. and it’s crucial to take the stairs instead of an elevator. only by doing things mentioned above can i get myself out of danger. 8+8+3 life is colorful but full of danger, so our students must learn some basic skills to prevent ourselves. for instance, when a fire breaks out, i can try to put it out by myself if it isn’t very big. but if it is out of control, i must dial 119 to ask for help immediately. i should stay calm and tell the firemen where

2014上海中考英语首字母填空专项练习 (一) Sleep is not the same every night. We experience some deep sleep and some active sleep( 积极睡眠), which is when dreams happen. You might think sleepwalking( 梦游) would happen in active sleep, but a person isn't physically active d 86 active sleep. Sleepwalking usually happens in the first few hours of sleep in the stage called slow-wave( 慢波)or deep sleep. Not all sleepwalkers a 87 walk. Some simply sit up or stand in bed or act like they're awake when, in fact, they're asleep! Most, however, do get up and move around for a few seconds or for as long as half an hour. Sleepwalkers' e 88 are open, but they don't see the same way they do when they're awake and often think they're in different rooms of the house or different places altogether. Sleepwalkers tend( 往往会) to go back to bed on their own and they won't r 89 it in the morning. Doctors say sleepwalking sometimes occurs when a person is sick, has a fever, is not getting e 90 sleep, or is stressed. If sleepwalking occurs frequently, every night or so, it's a good idea for your mom or dad to take you to see your doctor. But occasional(偶然的) sleepwalking generally isn't something to worry about, a 91 " it may look funny or even scary (惊恐的) for the people who see a sleepwalker in action. It's important, of course, that the person is kept safe.

D. 3 考点:二次根式的乘除法.菁优网版权所有 分析:根据二次根式的乘法运算法则进行运算即可. 解答:解:?=, 故选:B. 点评:本题主要考查二次根式的乘法运算法则,关键在于熟练正确的运用运算法则,比较简单. 2.(4分)(2014年上海市)据统计,2013年上海市全社会用于环境保护的资金约为60 800 000 000元,这个数用科学记数法表示为() A.608×108 B.60.8×109 C. 6.08×1010 D. 6.08×1011 考点:科学记数法—表示较大的数.菁优网版权所有 分析:科学记数法的表示形式为a×10n的形式,其中1≤|a|<10,n为整数.确定n的值时,要看把原数变成a时,小数点移动了多少位,n的绝对值与小数点移动的位数相同.当原数绝对值>1时,n是正数;当原数的绝对值<1时,n 是负数. 解答:解:60 800 000 000=6.08×1010, 故选:C. 点评:此题考查科学记数法的表示方法.科学记数法的表示形式为a×10n 的形式,其中1≤|a|<10,n为整数,表示时关键要正确确定a的值以及n的值. 3.(4分)(2014年上海市)如果将抛物线y=x2向右平移1个单位,那么所得的抛物线的表达式是()

A.y=x2﹣1 B.y=x2+1 C.y=(x﹣1)2 D.y=(x+1)2 考点:二次函数图象与几何变换.菁优网版权所有 专题:几何变换. 分析:先得到抛物线y=x2的顶点坐标为(0,0),再得到点(0,0)向右平移1个单位得到点的坐标为(1,0),然后根据顶点式写出平移后的抛物线解析式. 解答:解:抛物线y=x2的顶点坐标为(0,0),把点(0,0)向右平移1个单位得到点的坐标为(1,0), 所以所得的抛物线的表达式为y=(x﹣1)2. 故选C. 点评:本题考查了二次函数图象与几何变换:由于抛物线平移后的形状不变,故a不变,所以求平移后的抛物线解析式通常可利用两种方法:一是求出原抛物线上任意两点平移后的坐标,利用待定系数法求出解析式;二是只考虑平移后的顶点坐标,即可求出解析式. 4.(4分)(2014年上海市)如图,已知直线a、b被直线c所截,那么∠1的同位角是() A.∠2 B.∠3 C.∠4 D.∠5 考点:同位角、内错角、同旁内角.菁优网版权所有 分析:根据同位角:两条直线被第三条直线所截形成的角中,若两个角都在两直线的同侧,并且在第三条直线(截线)的同旁,则这样一对角叫做同位角可得答案. 解答:解:∠1的同位角是∠2, 故选:A. 点评:此题主要考查了同位角,关键是掌握同位角的边构成“F“形.
