(2分)四、阅读理解(1)分)①我找来两只强壮的白蝎，并将它们放在一起，用稻草拔弄，激怒它们。

在我的挑拨之下，它们决定斗一斗。

是我一直在中间挑拔，但是它们却将火发在对方身上。

那对大钳子，被它们举在头上，威慑着对方；当两对钳子抵在一块的时候，尼端的毒刺突然向前伸展，一下下地试探着。

在两根刺的尖端，各挂着一颗透明的小水珠，那是毒囊中分必出来的毒液。

②战斗在一瞬间结束，一只白蝎将另一只刺个正着。

受伤的一只在几分钟之后便会倒地毙命，而胜利者则十分平静，不动声色地上前，开始嘴食失败者的尸体，可能是对方尸体太大，也可能是蝎子的嘴太小，总之这顿进食要持续四五天，中间几乎不停歌，吃掉失败者，而且还是同类，蝎子可以为自己吃掉失敗的同类找一个很好的理归，那就是：胜者为王败者为寇。

将死去的敌人吃掉，尽管对方是自己的同类，这种动物还是有很多的，这种事情永远不会发生在人身上。

还没听说过在战争中一方会把另一方吃掉的。

至于为什么人类不会去吃自己的同类，我也搞不清楚。

六年级奥数周周练第13周代数法解题（教师版）----1e79a74c-6eaa-11ec-adb0-7cb59b590d7d 六年级奥数周周练第13周代数法解题（教师版）六年级奥林匹克周练习第13周代数法解题一、知识要点有一些数量关系比较复杂的分数应用题，用算术方法解答比较繁、难，甚至无法列式算式，这时我们可根据题中的等量关系列方程解答。

二、精练【例题1】某车间生产甲、乙两种零件，生产的甲种零件比乙种零件多12个，乙种零4所有零件均合格，只有a类零件合格。

共有42个合格零件。

分别生产了多少零件？5【思路导航】这个问题很难用算术方法解决。

根据两种类型的42个合格零件，可通过方程进行求解。

解：设生产乙种零件x个，则生产甲种零件（x+12）个。

4（x+12）×x=42543x+9+x＝425593x＝42－955x＝1818+12＝30（个）答：生产了30种零件，18种零件。

1六年级奥林匹克周练习名称：__________________练习1：1.某校参加数学竞赛的女生比男生多28人，男生全部得优，女生的得优，男、女生4.共有42名获奖者。

有多少男选手和女选手？解：设男生参赛的有x人，则女生参赛的有（x+28）人。

3x+（x+28）×=424x＝1212+28＝40（人）有12个男孩和40个女孩。

22.有两盒球。

第一个盒子比第二个盒子多15个。

第二个盒子里的所有球都是红球，第一个盒子里的球都是红球，5已知红球一共有69个，两盒球各有多少个？解决方案：如果第二个盒子有x个球，第一个盒子有（x+15）个球。

二（x+15）×+x＝695x＝4545+15＝60（个）A:第一个盒子里有60个球，第二个盒子里有45个球。

113.六年级的A班比B班少4人。

A班和B班的一些人参加课外数学小组。

两个班都有29人。

a班和B班有多少人？解：设乙班有x人，则甲班有（x－4）人。

11（x－4）×+x＝2934x＝5252－4＝48（人）A:A班有48人，B班有52人。

As my year as chief resident(进修医生) drew to a close, I asked myself this question 36 more t han one occasion.The answer, I concluded, was 37 . When you can say to yo urself, “There is no surgical patient I cannot treat competently , treat just 38 or better than any other surgeon”— then, an d not until then, you are 39 a surgeon. I was 40 that poin t.41 , for example, the emergency situations that we met almost every night. The first few months of the year I had 42 th e ringing of the telephone. I knew it meant another critical deci sion to be 43 . Often, after I had told Walt or Larry what to d o in a particular 44 , I’d have trouble getting back to sleep . I’d 45 all the facts of the case and, often, wonder 46 I h ad made a poor decision. More than once at two or three in th e 47 , after lying awake for an hour, I’d get out of 48 , dres s and drive to the hospital to see the patient myself. It was the only 49 I could find the 50 of mind I needed to relax.Now, in the last month of my residency, 51 was no longer a problem. Sometimes I still couldn’t be sure of my dec ision, but I had learned to 52 this as a constant problem for a surgeon. I knew that with my knowledge and experience, a ny decision I’d made was bound to be a 53 one. It was a ni ce feeling.This all sounds conceited(自负的) and I guess it is — 54 a surgeon needs conceit. He ne eds it to encourage him in trying moments when he’s bothere d by the 55 and uncertainties that are part of the practice o f medicine.

In the first forty days a boy had been with him. But after forty days without a fish the bo y’s parents had told him that the old man was now definitely a nd finally salao, which is the worst form of unlucky, and the bo y had gone at their orders in another boat which caught three good fish the first week. It made the boy sad to see the old m an come in each day with his skiff empty and he always went down to help him carry either the coiled lines or the gaff (鱼钩) and harpoon (鱼叉) and the sail thatwas furled around the mast (桅杆). The sail was patched with flour sacks and, furled, it looke d like the flag of permanent defeat.The old man was thin and gaunt with deep wrinkles in the bac k of his neck. The brown blotches（斑点）of the skin cancer the sun brings from its reflection on the trop ic sea were on his cheeks. The blotches ran well down the sid es of his face and his hands had the deep-creased scars from handling heavy fish on the cords. But non e of these scars were fresh. They were as old as erosions in a fishless desert.Everything about him was old except his eyes and they were t he same color as the sea and were cheerful and undefeated. “,” the boy said to him as they climbed the bank from where th e skiff was pulled up. “I could go with you again. We’ve madesome money.”The old man had taught the boy to fish and the boy loved him.“No,” the old man said. “You’re with a lucky boat. Stay with th em.”“But remember how you went eighty-seven days without fish and then we caught big ones every day for three weeks.”“I remember,” the old man said. “I know you did not leave me because you doubted.”“It was papa who made me leave. I am a boy and I must obey him.”“I know,” the old man said. “It is quite normal.”“He hasn’t much faith.”“No,” the old man said. “But we have. Haven’t we?”“Yes,” the boy said. “Can I offer you a beer on the Terrace an d then we’ll take the stuff home.”“Why not?” the old man said. “Between fishermen.”31. The boy left the old man and went in another boat to fish b ecause .A. the old man preferred to fish aloneB. the old man was unluckyC. the boy’s parents ordered him toD. the old man’s sail suggested a permanent defeat32. After reading this passage, we may safely conclude that .A. the old man was insistent and not afraid of failureB. the boy’s papa had confidence in everythingC. the old man caught big fishes during eighty-seven daysD. the boy obeyed his father because he had some doubts ab out the old man33. What might happen after the last paragraph?A. The old man and the boy might go to fish with other fisher men.B. The old man might go to have a drink with the boy.C. The old man and the boy might go to enjoy beer at the old man’s home.D. The old man might go to tell the boy’s papa about the secr ets between fishermen.BEconomics professor Fred Joutz says how Americans spend t he weekend after Thanksgiving is a good indication of how consumers feel about the future.With the unemployment rate above 10 percent, Joutz says A mericans are saving more and spending less. “Credit is still st rictly controlled whether through credit cards or through borro wing from banks,” he said. Some retailers are attracting consu mers by opening on Thanksgiving Day, when shops are traditi onally closed. Other stores open their doors anywhere from midnight to four in the morning.And shoppers will be lining up in front of the doors in order to be one of the firstones to walk through and get a big discount. Electronics like fl at screen TVs are usually the first items to go. Sandy Thomas says it’s an annual family tradition and well worth it. “I just sa ve maybe half of what I would have spent on a regular, you know, shopping trip,” she s aid.Economists say consumers will spend money this Black Frid ay, but they will spend it more carefully.34. The underlined word “slash” in the first paragraph probabl y means _________.A. reduceB. raiseC. increaseD. change35. The sentence “This day should be a shopper’s dream.” sh ould be placed between ________.A. paragraph two and paragraph threeB. paragraph one and paragraph twoC. paragraph three and paragraph fourD. paragraph five and paragraph six36. Why are many stores increasing security according to the passage?A. Because there are too many people saving more and spen ding less.B. Because it’s a time when they begin making their profits for t he year.C. Because last year a crowd of bargain-hunters caused an accident.D. Because many stores open their doors from midnight to fo ur a.m.37.What can we learn from the passage?A. Christmas shopping is traditional time and this year it is no exception.B. Electronics like flat screen TVs are usually least discounted .C. The economy only affects consumers on that bargain day.D.
