Being Left－handed in a Right－handed World
The world is designed for right－handed people，but why does a tenth of the population prefer the left? 1
The answer to it remains a bit of a mystery.Since scientists have noticed that left－handedness tends to run in families，it's assumed that left－handedness has a genetic(基因的) component to it. 2 In fact，identical twins，who share the same genes，can sometimes prefer to use different hands.There are also plenty of theories on what else might determine which hand you write with，but many experts believe that it's kind of random.
Historically，the left side and left－handedness have been considered a negative thing by many cultures. 3 In some areas，the left hand became known as the “unclean” hand.In many religions，the right hand of God is the favored hand.For example，Jesus sits at God's right side.God's left hand，however，is the hand of judgement.Various activities and experiences become rude or even signs of bad luck when the left hand becomes involved.In some parts of Scotland，it is considered bad luck to meet a left－handed person at the start of a journey. 4 A person giving directions will put their left hand behind them and even physically try to point with their right hand if necessary.In some Asian countries，eating with the left hand is considered impolite.
5 People come to realize that left－handedness is natural.People even noticed that many famous people are left－handed，including Benjamin Franklin，Leonardo Da Vinci，and Charlie Chaplin.Some researchers find out that lefties are more creative and can deal with abstract thinking better.The left－handedness is more easily adaptable to the right－handed world as well.Being left－handed is no longer a sad story now; instead，it is a wonderful gift or maybe it is something you should take pride in.
A. In other words，left－handers are born that way.
B．Left－handedness used to be regarded as a disability.
C．The unfavorable associations of the use of the left hand among cultures are varied.
D．Why do they prefer to use their left hand rather than their right hand for routine activities?
E．Why do some parents force their left－handed children to become right－handed when writing?
F．In Ghana，pointing，gesturing，giving or receiving items with the left hand is considered rude.
G．Fortunately，nowadays most societies and cultures no longer reject left －handedness like before.
本文是一篇说明文，文章主要介绍了人们使用左手的原因，过去对左撇子的误解以及现如今人们不再像以前那样拒绝左撇子了。
1．D[上句提到：但是为什么有十分之一的人喜欢用左手，第二段首句提到：这个问题依然有很多谜团。可知此处是在询问“为什么他们喜欢用左手而不是右手从事日常活动呢？”]
2．A[上句提到：由于科学家注意到左手倾向于在家人之间遗传，人们认为左撇子有这方面的基因成分。因此可以判断有一些人一出生就是那个样子。]
3．C[上文提到：历史上，在许多文化中，使用左手一直被认为是负面的事情。下文提到：在一些地区左手被认为“不干净”。在许多宗教中，上帝的右手是最受欢迎的手。可知不同的文化对使用左手不利的联系各不相同。]
4．F[上文提到：当左手参与的时候，各种各样的活动或经历变成粗鲁甚至是坏运气的标志。在苏格兰一些地区，在旅行开始时遇见一个左撇子会被认为运气不好。因此下句应该是举使用左手被认为粗鲁的例子。]
5．G[根据本段内容并结合空后第一句“People come to realize that left－handedness is natural.”可知，本段主要讲述现如今大多数社会和文化不再像以前一样拒绝左撇子了。]

(2016·全国丙卷)
Everyone knows that fish is good for health. 16 But it seems that many people don't cook fish at home.Americans eat only about fifteen pounds of fish per person per year，but we eat twice as much fish in restaurants as at home.Buying, storing, and cooking fish isn't difficult. 17 This text is about how to buy and cook fish in an easy way.
18 Fresh fish should smell sweet：you should feel that you're standing at the ocean's edge.Any fishy or strong smell means the fish isn't fresh. 19 When you have bought a fish and arrive home, you'd better store the fish in the refrigerator if you don't cook it immediately, but fresh fish should be stored in your fridge for only a day or two.Frozen fish isn't as tasty as the fresh one.
There are many common methods used to cook fish. 20 First, clean it and season it with your choice of spices (调料)．Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound.(A larger one will take more time.) Then，it's ready to serve.
A．Do not buy it.
B．The easiest is to steam it.
C．This is how you can do it.
D．It just requires a little knowledge.
E．The fish will go bad within hours.
F．When buying fish, you should first smell it.
G．The fats in fish are thought to help prevent heart disease.
本文是一篇说明文。人人都知道吃鱼有利于身体健康，但在家做鱼的人似乎不多。于是，
本文作者介绍了能买到新鲜的鱼的技巧以及一种简单的做鱼方法。
16．G[解本题可用句意判断法。空格前说“人人都知道吃鱼有益健康”，故本空应该
接上句说吃鱼的好处，由此可知选G项“人们认为鱼的脂肪有助于预防心脏病”。本设空类
型为细节理解类。]
17．D[解本题可用句意判断法。空格前说“买鱼、储藏鱼、做鱼并不难”，空格后说“本文就是关于如何买鱼并用一种简单方法做鱼的”。综观各选项，D项“这只需要一点儿
知识”与上下文语意衔接紧密，故为答案。本设空类型为过渡句类。]
18．F[解本题可用词汇锁定法。由空格后的smell sweet可锁定F项中的smell it。将F项代入空格后，语境为“买鱼时，你应该先闻一闻。新鲜的鱼闻起来不错”。句意衔接
紧密，故答案为F项。本设空类型为细节理解类。]
19．A[解本题可用句意判断法。空格前说“任何鱼腥味或浓烈的臭味都说明这鱼不新鲜”，理所当然，这样的鱼不能买，故选A项。本设空类型为细节理解类。] 20．B[解本题可用关联逻辑法。空格前说“鱼有很多普通做法”，空格后开始列举步骤，由此可推测空格处应该是指出众多方法中的一种。故选B项“最简单的(方法)是蒸鱼”。本设空类型为过渡句类。]

Everyone wants to become a better person，but many of us don't know what to do.
21 But I think everyone deserves respect and can become a better person.If you really want it，you can change yourself and your habits by taking a few little steps described below.
●Pursue your passion.It's important to find yourself and pursue your passion.Learn to listen to your inner self，even when someone is trying to bring you down.Some people try to bring you down because they're too weak and cowardly to pursue their passions and they don't think you should pursue yours.Don't listen to them.Spend time with yourself and think about the thing that brings you joy. 22
● 23 Another important thing to do to be a better person is to learn how to keep your dignity.Keep in mind that only you're responsible for your choices and decision in life and never get down on yourself when you do something wrong.Don't let anyone or anything bring you down and remind yourself that your life is unique，special and really worthwhile.
● Share your time，energy and talents. 24 You might not get aware of them，but you have them.Sharing your time，energy and talents can help become a better person，so learn to share more of your precious time with others and help people
in need and you will feel much better about yourself.
●Learn something new.You should never stop learning something new.That you are in your 30s or 40s，or even 60s，doesn't mean you can't learn a new language or other interesting things.Knowledge is always great. 25 When you are a well－educated person，everyone respects you and your knowledge.
A. Generally speaking，a better person must be a talented person.

21．C[上文提到，人人都想成为一个更好的人，但很多人又不知该如何去做。而空格后讲人人都应该得到尊重而且可以成为一个更好的人。根据“But”可知，空格处与下文构成转折，故C项“生活如此艰难以至于我们经常犯我们不想犯的错误”即承接上文话题，又与下文构成转折关系，符合语境。故C项正确。]
22．G[根据该段主题句和内容可知，该段主要讲述发现自我和追逐激情是非常重要的。因此不要被别人的言行所诱惑，花点时间考虑一下带给你快乐的那些事。G项“你很快就会发现你的热情并开始追寻它”承接上文中的“passion”，并照应该段主题，符合语境。故G项正确。]

二次根式培优 一、知识的拓广延伸 1、挖掘二次根式中的隐含条件 一般地，我们把形如a a() ≥0 的式子叫做二次根式，其中0 a≥。 根据二次根式的定义，我们知道：被开方数a的取值范围是0 a≥，由此我们判断下列式子有意义的条件： 1 (1; 2 (4); 1 x ++ -+ + 2、 教科书中给出： (0) a a =≥，在此我们可将其拓展为： a a a a a a 2 == ≥ -< ? ? ? || () () （1）、根据二次根式的这个性质进行化简： ①数轴上表示数a 的点在原点的左边，化简 2a ②化简求值： 1 a a= 1 5 ③已知， 1 3 2 m -<< ，化简2m ④______ =； ⑤若为a,b,c ________ =; ___________ =. （2）、根据二次根式的定义和性质求字母的值或取值范围。 ①若1 m=,求m的取值范围。 4x =-，则x的取值范围是＿＿＿＿＿＿＿＿＿＿＿． ③若a= ④3,2xy 已知求的值。 二．二次根式a的双重非负性质：①被开方数a是非负数，即0 ≥ a
②二次根式a 是非负数，即0≥a 例1. 要使1 21 3-+ -x x 有意义，则x 应满足（ ）． A ．21≤x ≤3 B ．x ≤3且x ≠21 C ．21＜x ＜3 D ．2 1 ＜x ≤3 例2（1）化简x x -+-11＝_______． (2) x ＋y )2，则x －y 的值为( ) (A)－1． (B)1． (C)2． (D)3． 例3(1)若a 、b 为实数，且满足│a －2│+2b -=0，则b －a 的值为( ) A ．2 B ．0 C ．－2 D ．以上都不是 (2)已知y x ,是实数，且2)1(-+y x 与42+-y x 互为相反数，求实数x y 的倒数。 三，如何把根号外的式子移入根号内 我们在化简某些二次根式时，有时会用到将根号外的式子移入根号内的知识，这样式子的化简更为简单。在此我们要特别注意先根据二次根式的意义来判断根号外的式子的符号。如果根号外的式子为非负值，可将其平方后移入根号内，与原被开方数相乘作为新的被开方数，根号前的符号不会发生改变；如果根号外的式子为负值，那么要先将根号前的符号变号，再将其其平方后移入根号内，与原被开方数相乘作为新的被开方数。 （1）、 根据上述法则，我们试着将下列各式根号外的式子移入根号内： ①- ②(a -（2）、利用此方法可比较两个无理数的大小。 (2)2-—3 四，拓展性问题 1、 整数部分与小数部分 要判断一个实数的整数部分与小数部分，应先判断已知实数的取值范围，从而确定其整数部分，再由“小数部分=原数—整数部分”来确定其小数部分。 例：（1）1的整数部分为a ，小数部分为b ，试求ab —b 2的值。 （2）若x 、y 分别为 8-2xy —y 2的值。 （3 a ，小数部分为 b ，求a 2+b 2 的值。 （4）若________a a b a b ==是的小数部分，则。 5a a b -（的整数部分为a ，小数部分为b ，求的值。 2、巧变已知，求多项式的值。 32351 x x x x = +-+（1）、若的值。
五年级语文上册阅读理解专项训练（一） 一次报告会（节选） 那是下午在“新长征突击手报告会”上的事。某饭店的青年厨师介绍经验后说：“同学们，我现在已会做150多样菜，会刻40多种‘萝卜花’，会……” 青年厨师接着解释道：“同学们大概不知道‘萝卜花’是什么玩艺儿吧？下面我给你们表演一下刻‘萝卜花’！” 只见青年厨师从书包里掏出两个红心萝卜，又拿出一把小刀，就坐在桌前刻上了。他边刻边说：“我先刻一朵‘月季花’！” 同学们都觉得很新奇，大家目不转睛地望着台上。 青年厨师几下就把萝卜皮拉掉了，然后又熟练地这儿切一下，那儿刻一刀，不到一分钟的工夫，一朵十分逼真的“月季花”就在他手里“诞生”了！ 大会主席举着这朵“月季花”绕场一周。同学们都赞叹不已： “嘿，真像啊！” “根本就看不出是什么做的！” “哎，就像用玉石雕出来似的！”…… 这时，青年厨师又拿起一个稍大的萝卜，说：“再刻一只‘仙鹤’。它的眼睛是花椒粒儿，腿和翅膀是紫萝卜！”说罢，他又一刀接着一刀地刻开了。他边刻边说，告诉我们他精心制作过一束“萝卜花”敬献给我们的国家领导人；还讲到外国友好人士对“萝卜花”的热情赞扬。刚说了不大工夫，一只玲珑剔透的“仙鹤”就活灵活现地展现在人们的眼前了。 啊，真是运刀如神，萝卜开花呀！ 我听了厨师的讲述，看看这只美丽的“仙鹤”，心里想了许多许多：一位年轻的厨师，能够创作如此新颖而奇异的艺术品来，是多么感人！看来，真是行行出状元啊！我们现在努力学习，掌握本领，将来踏踏实实干，一定会为祖国做出贡献的。 “萝卜花”！我将永远记住它。 1.划去错误读音。 行行（háng xíng）出状元嘿（hēi hèi），真像啊！ 2.解释带点的字。 赞叹不已．（）活．灵活现（） 3.课文中第一处省略号省略了__________________________________________ 。第二处省略号省略了_____________________________________________。 4.把全文分成3段，用“‖”表示。 5.同学们对厨师刻的月季花都赞叹不已，原因有两点：(1)____________________； (2)_________________________________________。 6.写出文章的主要内容。 _____________________________________________________________________ _____________________________________________________________________ 7.这位某饭店青年厨师的光荣称号是_______________。本文记叙他雕刻萝卜花做出 成绩的事，说明___________________。

1第Ⅱ卷（共45分） 第四部分书面表达（共两节，满分45分） 第一节阅读表达（共5小题；每小题3分,共15分） 阅读下面短文并回答问题，然后将答案写到答题卡相应的位置上（请注意问题后的字数要求）。 ［1］We all know eating out can be a lot of fun. There’s the experience of having someone wait on your every need, the social aspect of being in a restaurant with friends and, of course, the great benefit of the lack of in-home cleanup. ［2］We all also know eating out can be expensive, and I’m pretty sure college isn’t the most financially successful time in a normal person’s life. That’s why eating at home for a majority of meals really is the only option for many college students. ［3］Eating at home doesn’t have to be dull, boring, or difficult. It can and should be an energetic, creative experience that transforms the way you look at food. When you cook for yourself, you know exactly how your pasta（意大利面）is going to turn out. You know where the greens in your salad come from. You know the olive oil you’re using really comes from olives that are pressed for the first time. Use eating at home as an opportunity to learn and develop your kitchen skills. I promise you they will remain useful and rewarding for the rest of your life. ［4］Another important concept is to keep in mind that when it comes to shopping for food—less quantity, more quality. Buy base ingredients that are fresh, as local as possible and beautiful, and anything you cook will improve greatly. I promise you will be just as satisfied by eating a little bit less of something with a lot more quality. ［5］I am not saying eating out is a bad thing. But I insist there are many more places that are not worth your cash. Put a little more effort into cooking for yourself at home and you will gain experience and appreciation for the world of food. 76. List three benefits of eating out according to the text. (no more than 20 words) ①②③ 77. Complete the following statement according to Paragraph 2.(no more than 4 words) Many college students have to eat at home because of . 78. What’s Paragraph 3 mainly about? (no more than 7 words) 79. What advice is given concerning shopping for food in Paragraph 4? (no more than 4 words) 80. Do you like eating at home? State your own reasons.（no more than 20 words） 第二节写作（满分30分） 假如你是李华，你打算参加2012年6月份举行的济南市中学生英语演讲比赛，你的演讲主题是环境问题。请根据以下要点写一篇演讲稿： 1. 介绍一种你所关注的环境问题； 2. 发表你对解决该问题的见解。 注意：1. 词数：120—150； 2. 可以适当增加细节，以便行文连贯。 Dear teachers and schoolmates，

When she was thirteen, she was surfing the Internet regularly, but she couldn?t find anywhere for teenagers to meet and talk. And one day she thought, “If I had my own website, I?d make it a really interesting site for teenagers.” [2] So, when Ashley was sixteen, she launched her own website, called GooseHead. She had no idea how big a success it would be, but three years later, the site was the most successful teen site in the USA! It was getting 100,000 hits every day, and Ashley had about 30 employees. [3] After a few years, the website closed down. Then Ashley, who lives in Los Angeles, was asked to write a book called The GooseHead Guide to Life. The book is about how to design a website and start a business. It begins with a section called “All A bout Ashley,” where Ashley tells readers what it is like to be the boss of a company when you are only sixte en! “I was so happy. But it was crazy in a lot of ways.I got very stressed. I mean, I was only sixteen ---- I didn?t even have a car! If you were sixteen and you had your own company, you?d be stresse d, too!” [4] In an interview, Ashley gave advice to teenagers who wanted to start their own business, “Just be strong and have your dreams and work hard at them. And don?t listen when , because I heard …no? a lot. Just keep going until you hear …yes?!” 76. For what purpose did Ashley create GooseHead? (no more than 10 words) 77.

Do you frequently ignore work, study, and other activities to check your phone for messages? Are you anxious and restless if you are separated from your mobile phone? Do you hardly ever use your phone to talk any more,and do your thumbs hurt from texting too much? [2] If , then it is very possible that you are a textaholic. A textaholic can be defined as someone who is addicted to sending and receiving messages. The main symptoms are a strong desire to text messages, which takes precedence (优先)over everything else, and bad moods, low spirits and a lack of self-confidence if messages fail to come in. The root of the problem, as with many addictions, is the desire to escape from emotional difficulties such as stress, anxiety and relationship problems. Experts warn that text addiction is likely to become the most common form of addiction in the future, especially among the young. [3] So what can you do if you think you may be a textaholic? The key is to get yo ur life back in balance. Make sure you resist the urge to answer every message you receive, and consider leaving your mobile phone behind occasionally when you go out.
