Ⅴ.阅读理解
Eight monkeys were put in a room. In the middle of the room was a ladder, leading to a bunch of bananas hanging from a hook on the ceiling. Each time a monkey tried to climb the ladder, all the monkeys were sprayed with ice water, which made them miserable.
Soon enough, whenever a monkey attempted to climb the ladder, all of the other monkeys, not wanting to be sprayed, set upon him and beat him up.
Soon, none of the eight monkeys ever attempted to climb the ladder. One of the original monkeys was then removed, and a new monkey was put in the room.
Seeing the bananas and the ladder, he wondered why none of the other monkeys were doing the_obvious_thing,_but, undaunted (无畏的), he immediately began to climb the ladder. All the other monkeys fell upon him and beat him silly. He had no idea why. However, he no longer attempted to climb the ladder.
A second original monkey was removed and replaced. The newcomer again attempted to climb the ladder, but all the other monkeys beat the hell out of him. This included the previous new monkey, who, grateful that he's not on the receiving end this time, participated in the beating because all the other monkeys were doing it. However, he had no idea why he was attacking the new monkey.
One by one, all the original monkeys were replaced. Eight new monkeys are now in the room. None of them has ever been sprayed with ice water. None of them attempts to climb the ladder. All of them will enthusiastically beat up any new monkey who tries, without having any idea why.
And that's how any company's policy/process gets established!
文章大意：本文通过对一些猴子做试验的结果告诉我们：人们是如何适应一些组织的政策或管理的。
1．How many monkeys are needed to complete the experiment?
A．8. B．10.
C．14. D．16.
答案：D 细节理解题。由文章首段中的“Eight monkeys were put in a room.”以及倒数第二段中的“One by one, all the original monkeys were replaced.”可知总共需要16只猴子。
2．The underlined part “the obvious thing” in the 4th paragraph refers to the fact that ________.
A．no monkey wanted to eat the bananas
B．no monkey dared to climb the ladder
C．any monkey could get the bananas using the ladder
D．all monkeys attempted to keep the bananas to themselves
答案：C 短语理解题。结合文章第四段中的“Seeing the bananas and the ladder...he immediately began to climb the ladder”可知此处指用梯子可以够到香蕉这件事。
3．Why did the first new monkey feel grateful?
A．Because he got the bananas he desired.
B．Because he knew why he was attacked.
C．Because he participated in the attack.
D．Because he wasn't the target to be beaten.
答案：D 细节理解题。由第五段中的“This included the previous new monkey...why he was attacking the new monkey.”可知，第一只新来的猴子看到是第二只新来的猴子惨遭毒打，因此它庆幸这次挨打的不是自己。
4．This passage is intended for those who ________.
A．want to learn to manage a company
B．desire to make their lessons interesting
C．need to learn how to keep animals as pets
D．expect to bring up their children scientifically
答案：A 推理判断题。由文章最后一段“And that's how any company's policy/process gets established！”可知这篇文章对想要学习管理公司的人有一定的启发，故这类人就是本文的写作对象。

文章大意：本文是一篇记叙文，讲述了一位医生教给他的医学学生的一堂实践课。
1．A.told B．led
C．turned D．pointed
答案：C 考查动词辨析。此处表示医生转向其中的一个学生，turn to“转向”，符合句意。
2．A.wrong B．matter
C．trouble D．problem
答案：A 考查固定用法。问题问的是“这个人出什么问题了”，可以用“What's wrong with...”或“What's the matter with...”，故答案为A。
3．A.find B．look
C．keep D．get
答案：A 考查固定短语，find out“查明，发现”，符合句意。
4．A.You're B．It's
C．There's D．He's
答案：C 考查固定句型。There is no need to do sth.“干某事是没有必要的”。
5．A.by B．with
C．in D．without
答案：D 根据上下文，“这位医生教育学生应该不问问题通过观察就知道这个人怎么了。”故without符合句意。
6．A.time B．way
C．place D．kind
答案：B 此处表达走路的方式。way表示“方式”，符合句意。
7．A.drying B．heating
C．burning D．taking
答案：C 考查动词辨析。既然是伤着膝盖了，肯定是在火里烧了，故burn符合句意。dry表示“干”，heat“加热”，take“带走”均不能造成伤着膝盖的结果。
8．A.right B．long
C．left D．broken
答案：A 根据文中“He has hurt his right knee.”可得知。
9．A.by B．in
C．at D．with
答案：C 考查介词。此处at表示“向或朝着某物的方向”，指朝着膝盖的方向。
10．A.rainy B．windy
C．fine D．stormy
答案：C 由后面说“在周六________是湿的，泥泞的”以及后面的but转折词可以推断昨天天气是晴朗的，故选C。
11．A.roads B．trees
C．shops D．buses
答案：A 根据理解可知周六是下雨了，下雨了只有“路”才能说是“wet and muddy”。故答案为A。
12．A.hurt B．fell
C．went D．put
答案：B 考查固定短语。fall down“跌倒”。
13．A.Saturday
B．Wednesday
C．Tuesday
D．Friday
答案：A 根据上下文应该是发了薪水当天就去喝酒了，结果下了雨衣服湿了又烤火造成了这个伤。而上面又说是星期六下雨了，我们可以推知是周六发的薪水，故答案为A。
14．A.much B．little
C．slowly D．happily
答案：A 从后文我们很容易看出是喝多了。
15．A.there B．here
C．dry D．wet
答案：D 因为周六路是湿的，是泥泞的，所以身上也就“湿了”，故选择wet。
16．A.way B．road
C．means D．side
答案：A 固定说法。on the way home“在回家的路上”。
17．A.way B．fire
C．light D．night
答案：B 既然是想让衣服干还有文章开头介绍的是火烧伤的，故此处是在“火”旁，故选择B。
18．A.If B．Because
C．So D．When
答案：B 考查连接词。喝多酒和跌倒在火上烧伤膝盖之间是前因后果的关系，故选择because。
19．A.wine B．food
C．coffee D．water
答案：A 考查名词。根据理解此处当然指喝多酒，wine是“白酒”的意思，符合句意。
20．A.right B．good
C．wrong D．it
答案：A 这位医生在讲解完自己的推测之后向这位受伤的人求证。“Is that right？”表示“对吗？”符合上下文语境。
Ⅲ.阅读理解
There are many interesting science experiments out there for young kids. You can wow your friends and teachers with them. All you have to do is to put a little effort into it and you should have no problem coming up with an interesting science experiment. One such experiment is to show your friends and teachers that you can make mothballs (樟脑丸)dance!
If you want to do it, first, be sure that you have got all the necessary science kits for your science experiment.
What you need for this experiment is a glass filled half full with water. Add a little bit of vinegar to your glass of water, about 1/3 or 1/4 of a cup (60 ml), and one teaspoon (10 ml) of baking soda, and then carefully stir the mixture. Drop a few mothballs into the glass and have your audience watch. As long as the surfaces of the mothballs become fairly rough, they should begin to bounce up and down in the glass.
You can also do a similar experiment with raisins (葡萄干) and clear pop,_such as Sprite. In this experiment, all you have to do is to fill a glass with Sprite and drop a few raisins into it. The raisins should begin to bounce up and down in the glass of Sprite. You can also replace the raisins with mothballs and you should get the same effect in the Sprite. This project works because the irregular surfaces of the mothballs and the raisins hold some CO2 bubbles (气泡), causing them to bounce up and down in a dancing motion.
文章大意：本文主要向我们介绍怎么做一个简单而有趣的科学实验。
1．The writer wrote this passage to ________.
A．explain why some science experiments are easy
B．encourage people to spend more time on science
C．tell us how good he is at doing science experiments
D．teach kids how to do an easy and interesting science experiment
答案：D 作者意图题。通过全文，可知作者主要向我们介绍怎么做一个简单而有趣的科学实验，故选D。
2．Which of the following things are needed in the experiment?
a．baking soda b．water c．mothballs d．salt e．vinegar f．sugar
A．bcef B．acde
C．abcd D．abce
答案：D 细节理解题。根据第三段的“a glass filled half full with water. Add a little bit of vinegar to your glass of water, about 1/3 or 1/4 of a cup (60 ml), and one teaspoon (10 ml) of baking soda”可知应选D。
3．The underlined word “pop” in Paragraph 4 probably refers to a ________.
A．mothball B．kind of vinegar
C．drink with bubbles D．special kind of raisin
答案：C 词义猜测题。根据“such as Sprite以及hold some CO2 bubbles”可知pop在这里是指含有二氧化碳的饮料。
4．From the last paragraph we can know ______.
A．why Sprite has some CO2 bubbles
B．what people usually use Sprite for
C．what scientists usually do with raisins
D．why the mothballs bounce up and down
答案：D 细节理解题。根据文章的最后一句“This project works because the irregular surfaces of the mothballs and the raisins hold some CO2 bubbles (气泡), causing them to bounce up and down in a dancing motion.”可知，樟脑丸为什么会上下跳动。

文章大意：本文主要讲述了对生活要乐观，要善于乐观地看待生活中一些不愉快的事情。
1. A. seriously B. cheerfully
C. friendly D. coldly
答案：B 上周一，在刚开始上课的时候，我兴致勃勃地问学生们周末过得怎么样。下文3空所在的句子有“in a good mood”，第二段有“I choose to be cheerful”的提示。B项意为“兴致勃勃地”，符合语境。其它选项不合语境逻辑。
2. A. cut B. pulled
C. dragged D. removed
答案：D 一个男生说，他的周末不太愉快，因为他的智齿被拔掉了，结果让他痛了一整天。D项意为“移除，除掉”，符合语境。A项意为“切，割，削”；B项意为“拉，扯”；C项意为“拖，拖曳”，均不合语境。
3. A. never B. seldom
C. always D. sometimes
答案：C 根据第二段“I choose to be cheerful”的提示可判断，我总能保持快乐的心情。
4. A. how B. what
C. where D. why
答案：A 根据“I choose to be cheerful”可判断，此处作者说的是人每天可以选择自己的生活方式，即：“每天早上，当你起床的时候，你可以选择如何面对一天的生活”。
5. A. lesson B. idea
C. story D. example
答案：D 作者为了论证“人起床的时候，可以选择如何面对一天的生活”，下文讲述了自己去一所社区大学上课途中车子抛锚但自己仍能乐观地看待此事的故事，即用该故事作例子论述自己的观点，故选D项。A项意为“教训”；B项意为“主意，观点”；C项意为“故事”，均不符合语境逻辑。
6. A. entered B. followed
C. exited D. took
答案：C 在这之前，我还在一所社区大学任教，那儿离我家17英里。几周前的一天，我驾车前往那所学校，驶离高速公路后，我转入了校园区。但在只差400多米就到学校的时候，我的汽车抛锚了。C项意为“驶离，离开”，符合题意。
7. A. died B. destroyed
C. settled D. parked
答案：A 根据下一句“I tried to start it again”的提示可判断汽车抛锚了，即熄火了，故选A项。B项意为“破坏”，C项意为“解决，定居”，D项意为“将车停在某处”，不合语境逻辑。
8. A. turn over B. turn down
C. turn off D. turn away
答案：A 根据下文“So I put my flashers on，grabbed my books，and __9__ down the road to the college.”的提示可判断我努力重新发动引擎，但就是发动不起来。A项本意为“翻倒；倾覆”，此处引申为将引擎由熄火转为发动，故选A项。B项意为“拒绝，使希望”；B项意为“关掉”；D项意为“不准……入内，走开，转过脸”，均不合语境。
9. A. moved B. marched
C. remained D. turned
答案：B 引擎发动不起来，而又得急于去上课，故我只好把指示灯打开，然后抓起课本直奔学校。B项意为“前进，走过”，符合语境。
10. A. required B. wanted
C. demanded D. arranged
答案：D 车子不可能总坏在路途中，所以我一到学校就马上打电话给汽车协会，让他们在我下课后安排一辆拖车过来，arrange for意为“为……作安排”，符合语境。A、B、C三项均为及物动词，后应直接跟宾语。
11. A. good B. bad
C. lucky D. hard
答案：C 倒数第三段中作者说：“我住在离这儿17英里的地方。其实我的车有可能在高速公路上的什么地方就坏掉了的，但庆幸的是，没有。相反，汽车是在离开了高速公路后才抛锚，而且距离学校很近。我还来得及上课，还能够安排拖车在课后来处理。如果我的汽车是注定了要在今天抛锚的，那在这个位置抛锚已经是非常幸运了。”由此可判断此处作者意为：“今天我真走运。”
12. A. However B. Therefore
C. Instead D. Besides
答案：C 作者认为他的车有可能在高速公路上的什么地方就可以坏掉，但却没有，即文中有“不是……而是……”之意。C项意为“代替，而是”，符合语境。
13. A. free B. lonely
C. terrible D. perfect
答案：D 作者认为自己的车没有在高速公路上坏掉，而是在离学校不远处坏掉，使自己走不多远就能赶到学校上课，故认为这是车子抛锚的完美之地。
14. A. wished B. asked
C. hoped D. meant
答案：D be meant to do sth.意为“注定……”，此句意为：“如果我的汽车是注定了要在今天抛锚的话，那在这个位置抛锚已经是非常幸运了。”
15. A. couldn't B. mustn't
C. shouldn't D. needn't
答案：A 作者的意思是，如果他的汽车是注定了要在今天抛锚的话，那不可能再找到比这个地方更方便的抛锚之处了。couldn't have done表推测，意为“不可能……”。
16. A. completed B. stopped
C. succeeded D. ended
答案：D 由上下文逻辑及文章的提示，可判断作者的车子抛锚的故事讲完了。D项意为“结束”，符合语境。A项意为“完成”，为及物动词；B项意为“停止”；C项意为“成功”，不符合语境。
17. A. Somehow B. Anyhow
C. Thus D. Therefore
答案：B 虽然是在大清早，但没有一个学生在打盹，作者认为是因为他讲的故事使他们感动了，即：“不管怎么样，总之他们好像是被我的故事触动了。”B项意为“无论如何，不管怎么说，总之”，符合语境。A项意为“不知何故”；C、D两项意为“因此”，均不合语境。
18. A. In addition B. In all
C. In fact D. In general
答案：C 作者认为或许感动学生的根本不是故事。实际上，从一个学生观察到我很高兴那一刻，他们就已经被感动了。
19. A. observation B. recognition
C. conclusion D. question
答案：A 由第18题解析可知。
20. A. talks B. says
C. speaks D. tells
答案：C 此段意为：“乔布拉曾经引述过一位印度智者的名言：‘你为人行事的本身，比你的语言更具说服力。’我认为这的确是真理。”Who在句中引导主语从句，这里应用speaks，故选C项。
Ⅲ.阅读理解
Science experiments are a fun way for kids to learn all about science. I will introduce a few great experiments and teach your child all about the wonders of inertia(惯性).
Coin Shoot
You'll need some coins, at least eleven, and a smooth table. Stack(堆叠) all but one of the coins on the smooth table, making sure that the “high rise” is straight. Coins with wide edges make this experiment easy to do. Flick (弹) the extra coin quickly towards the bottom of the stack so that it hits the bottom coin. The bottom coin from the stack should shoot out from under the other coins without changing the rest of the stack. With good aim and quick flicks of your finger, you should be able to shoot all of the coins out of the stack one by one. Because the inertia of the stack of coins is so great, the force from the flicked coin is not enough to make the entire stack move or fall down.
The Pencil Standing
Place a narrow piece of paper on a smooth table. Hold the paper so that most of it hangs off the table. Place a pencil on the paper so that it is standing straight. Now, slowly try to pull the paper out from under the pencil. What happens? Set up the paper and pencil again, and give the paper a fast pull. What happens to the pencil this time?
Since the still pencil wants to stay at rest, it will be against the fast movement of the paper. This means that when the paper is moved quickly out from under the pencil, the pencil remains standing straight. If the paper is moved slowly, the movement has a chance to influence the pencil, and it will fall down.
1．Which of the following is used in both of the two experiments?
A．A narrow piece of paper.
B．A number of coins.
C．A smooth table.
D．A new pencil.
答案：C 细节理解题。由第二段第一句和第三段第一句可知，两个实验中都用到了a smooth table。
2．What do we know about stacking the coins?
A．At least eleven coins are needed but one isn't stacked.
B．The more coins in the experiment, the better.
C．All the coins should be stacked straight.
D．Nine coins are stacked but two are not.
答案：A 细节理解题。根据第二段前两句可知，至少需要十一枚硬币，而且其中一枚不能与其他的摞在一起。
3．What result can we get if we do the first experiment well?
A．The stack of coins fall down on the table.
B．The bottom coin is flicked out of the stack.
C．All of the coins are taken away from the table.
D．All of the coins are shot out of the stack one by one.
答案：D 细节理解题。根据第二段倒数第二句可知，如果将这个实验做好，摞起来的硬币会一枚一枚地被击出。
4．Most of the paper hangs off the table so that ________.
A．we can pull it quickly
B．we can take hold of it
C．it can influence the pencil
D．the pencil can stand straight
答案：A 推理判断题。根据第三段倒数第二句“Set up the paper and pencil again，and give the paper a fast pull.”可推知，这样放纸条是为了能够迅速地抽出纸条，故答案为A项。

There are two kinds of changes—the chemical change and the physical change.
In a chemical change, there is a new substance formed. Breaking up water into hydrogen(氢气)and oxygen is a chemical change. In each of the chemical changes, at least one new substance is formed. A change is not a chemical change if it doesn't form a new substance.Physical changes are very common, too. There are many examples. You can make a physical change by tearing a piece of paper into two, or by cutting a piece of iron with a lathe(车床). Here paper is still paper, and the iron is still iron.Another way of making physical change is dissolving something in water. When you dissolve salt in water, the salt disappears, You may think that a new substance has been formed. But really there is no new substance. The salt is still salt. You can still taste it. So the dissolving of anything is a physical change.
When water freezes, the change is also a physical one. The water changes from a liquid to a solid. But it is still the same substance. That is why the freezing of anything is a physical change.1.substance n. 物质

(2)On the top of the mountain stand a temple, and in the temple lives several old monks.( )
思路点拨
本题考查完全倒装句中的主谓一致问题。完全倒装句中，其谓语动词的单复数要依其后的主语而定。该句中的前半句中，主语为a temple，故谓语动词应该用stands；后半句中，主语为several old monks，故谓语动词应该用live。

(1)We got to the stage where we should sit down and have a good talk with our parents.( )
(2)We got to the stage which we should sit down and have a good talk with our parents.( )
思路点拨
考查定语从句。先行词stage在此意为“状态，阶段”，表示抽象的地点，因此用关系副词where引导定语从句。除stage外，这种模式的地点词还有point, situation, case等。句式训练
我已经到了应该为自己做决定的那个时刻了。

I used to hate science, because it was difficult and complicated for me. Although through physics, I know the followings: water has three states, which are solid, liquid and gas; when water boils, it gives off steam; when heated, metals, such as iron used in electrical equipment, potassium, sodium, calcium and copper and so on, expand rather than contract; steel is a mixture of iron with other substances. I still have no much interest in science. But half a year ago, a lecture made by Professor Lee, who had made many discoveries in his areas of science, astonished and changed me. We were proud of him for his winning the Nobel Prize for Chemistry. The aim of the lecture was to develop the interest of teenagers in science. Professor Lee, director of Chemistry Department of a university, brought many science facilities with him, including balance, tongs, tubes, crucible etc. He did several experiments, and one of them interested me. We drew a conclusion with his help that iron doesn't rust in dry air and in air－free water but rust in ordinary water because iron reacts with oxygen in the water. Professor Lee also told us copper makes partial reaction when heated in oxygen, while it makes no reaction when it is placed in water.
What a wonderful world! At the end of the lecture, Professor Lee said teenagers were supposed to care more about the latest discoveries in science. Now I have known how snow forms and how salt dissolves in water.译文：
我过去不喜欢科学，因为它对我来说很难，而且很复杂。尽管通过物理，我知道了下列一些事情：水有三态，即固体、液体和气体；当水沸腾时，它会释放出蒸汽；当金属，如用于电气设备中的铁、钾、钠、钙和铜等被加热时，它们会膨胀而不是收缩；钢是铁与其他物质的混合物。但我依旧对科学没什么兴趣。但半年以前，李教授作的一次演讲使我惊愕而且改变了我。这位李教授在他个人的(研究)领域里有很多的发现。他也因此获得了诺贝尔化学奖，我们都引以为豪。他这次演讲的目的是为了开发青少年对科学的兴趣。这位大学里的化学系主任，演讲时用随身带来的诸多科学设备，如天平、夹子、试管和坩埚等做了几个实验，其中一个引起了我的兴趣。在他的帮助下，我们得出结论：铁在干燥的空气中和没有空气的水中不生锈，但在普通的水中生锈，因为铁与水中的氧气发生化学反应。李教授还告诉我们铜在氧气中被加热，发生局部化学反应，而当它放在水中时，不发生反应。多么奇妙的世界呀！演讲结束时，李教授说青少年应该多关心科学上的最新发现。现在我已经知道雪是怎样形成的以及盐是怎样在水中溶解的。科学构建，高效作文

Man has a big brain. He can think, learn and speak. Scientists once thought that men are different from animals because they can think and learn. They know now that dogs, rats, and birds can learn too. Scientists are beginning to understand that men are different from animals because they can speak. Animals cannot speak. They make noises when they are afraid, or angry or unhappy. Apes can understand some things more quickly than humans, and one or two of them have learned a few words. But they cannot join words to make sentences. They cannot think like us because they have no language. Language is a wonderful thing. Man has been able to build a modern world because he has language. Every child can speak their own language very well when they are four or five—but no animals learn to speak. How do children do it? Scientists do not really know. What happens inside our body when we speak? They do not know. They only know that man can speak because he has a brain.

When you're curious_about something, and want to know more about it, you can use the way of asking questions. Asking questions is the first step to make discoveries and find interesting answers. The steps below can guide you during the research(研究)．
Step 1 On a notecard or piece of paper, write down the subject that you are interested in. Just get the main idea down. For example, you might write: Discover more about dinosaurs.
Step 2 Next, stop and think for a moment about what you already know about your subject. List what you already know like the sentences below：
(1) Dinosaurs lived long before human beings appeared.
(2) Dinosaurs lived on the earth for more than 150 million years.
(3) Some dinosaurs fed on(吃) plants, some on meat.
Step 3 What can you do with what you want to learn? By asking questions. On your paper, start writing down questions about the dinosaurs as you think of them：
(1) What's the best weather for dinosaurs to live in?
(2) How many kinds of dinosaurs are there?
(3) Have dinosaurs really disappeared?
Step 4 Armed_with_your_list_of_questions,_you can now go to the nearest library or computer to begin your research. As you learn more about your subject, you'll probably discover some new questions. For example, you might discover that dinosaurs disappeared about 65 million years ago. Why? What happened? Asking new questions can help you research your subject more widely.
If you always find something interesting to research, take time to organize (组织) your thinking by asking good questions. And remember learning more always brings more questions.
21．The underlined phrase “curious about” means ________.
A. worried about
B. bored with
C. eager to learn about
D. ready to do
答案：C 词义猜测题。由语境“want to know more about it”以及“asking questions”可推测curious about 意为“对……好奇”而“急于去了解”。
22．When you do some research, you should take the following steps ________.
a. list what you want to know
b. choose a research subject
c. list what you already know
d. discover new questions
A. d, c, b, a B. a, d, c, b

23．From the passage, we know ________.
A. dinosaurs appeared after human beings
B. not all the dinosaurs fed on meat
C. dinosaurs lived on the earth for 65 million years
D. dinosaurs lived in warm season
答案：B 细节理解题。由Step 2中的“Some dinosaurs fed on plants, some on meat.”可知，并不是所有的恐龙都以肉为主食，有些还吃植物。
24．What does “Armed with your list of questions” mean?
A. Putting your list of questions under your arm
B. Discussing your questions with your classmates
C. Writing down your list of questions
D. Taking your list of questions with you

(2014·辽宁卷)
Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the_opposite_is_true:_trees survive through their cooperation and support, passing around necessary nutrition “depending on who needs it”．
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌)networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
Simard talks about “mother trees”， usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.
“We didn't take any notice of it” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.
25．The underlined sentence “the opposite is true” in Paragraph 2 probably means that trees________ .
A．compete for survival
B．protect their own wealth
C．depend on each other
D．provide support for dying trees
答案：C 词义猜测题。从文中下一句的“trees survive enough their cooperation and support , passing around necessary nutrition ‘depending on who needs it.’”可知本题答案为C项。
26．“Mother trees” are extremely important because they ________.
A．look the largest in size in the forest
B．pass on nutrition to young trees
C．seem more likely to be cut down by humans
D．know more about the complex “tree societies”
答案：B 推理判断题。根据第四段第二句的“She explains how dying trees pass on the wealth to the next generation transporting important minerals to young trees so they may continue to grow”可知本题答案为B项。
27．The underlined word “it” in the last paragraph refers to ________.
A．how “tree societies” work
B．how trees grow old
C．how forestry industry develops
D．how young trees survive
答案：A 词义猜测题。第四段说的是树的社会系统，而第五段的第一句话的意思是：我们以前没有注意到这个事情。故本题答案为A项。
28．What would be the best title for the passage?
A．Old Trees Communicate Like Humans
B．Young Trees Are In Need Of Protection
C．Trees Are More Awesome Than You Think
D．Trees Contribute To Our Society
答案：C 主旨大意题。本文介绍了植物界的一种现象：树和树之间是相互依存的关系。母亲树会在临死前把营养传给下一代让它们继续生长。可知本题答案为C项。
C

29．The underlined phrase“curious about” in the first paragraph means ________.
A．worried about B．bored with
C．eager to learn about D．ready to do
答案：C 词义猜测题。由语境“want to know more about it”以及“asking questions”可推测curious about意为“对……好奇”。
30．When you do some research, you should take the following steps：________.
①list what you want to know
②choose a research subject
③list what you already know
④discover new problems
A．④③①② B．①④③②
C．②③①④ D．③②④①
答案：C 细节理解题。综合短文的四个步骤，可以看出首先要选择一个研究课题，只有C项的第一个步骤是此步骤。
31．What does the underlined sentence “Armed with your list of questions” mean?
A．Putting your list of questions under your arm.
B．Discussing your questions with your classmates.
C．Writing down your list of questions.
D．Taking your list of questions with you.
答案：B 细节理解题。由Step 2中的第三条“Some dinosaurs fed on plants, some on meat.”可知，并不是所有的恐龙都以植物为主食，有些还吃肉。
32．The best title of this passage is ________.
A．Discovering Dinosaurs
B．Asking Good Questions
C．Finding Subjects
D．Having Interesting Answers
答案：B 主旨大意题。由最后一段归纳得知。最后一段主要阐述学得多问题就多，应该拿出时间来考虑一些高水平的问题。
D
In 1950 an ordinary but imaginative electrical engineer named Christopher Cockerell began an experiment that was soon to change the world. He came up with an idea to make boats go faster by using a vacuum cleaner(真空吸尘器)．
Using his wife's vacuum cleaner he was able to reverse(使倒转)the motor so that it blew instead of sucking. The air that blew out beneath(在下面)acted as a cushion(垫子) against surfaces. Years later, his principle (原理)of cushioned air made it possible for the first hovercraft(气垫船)to be successfully built and tried out. A journey along the Amazon River proved to the world that the hovercraft was both wonderful and useful.
The invention that began in the kitchen and the boatyard of an ordinary home led to a thousand other inventions. Today hovercrafts carry passengers in comfort over rough channels and seas.
文章大意：本文是一篇记叙文，文章主要介绍了Christopher和他发明的气垫船。
33．The passage is mainly about ________.
A．the description of Christopher
B．Christopher and his wife's vacuum cleaner
C．Christopher and his invention
D．Christopher and a vacuum cleaner
答案：C 主旨大意题。文章介绍了Christopher和他发明的气垫船。
34．The aim of the experiment in 1950 was ________.
A．to speed up the boats
B．to change the world
C．to make the boats more comfortable
D．to improve vacuum cleaner
答案：A 细节理解题。文章第一段提到1950年Christopher“提出一个想法，使用真空吸尘器使小船跑得更快。
35．The underlined word “sucking” in the second paragraph probably means ________.
A．taking with great force
B．drawing with great force
C．pushing with great force
D．pulling with great force
答案：B。词义猜测题。前面说的“使倒转”“吹”，加上instead of表示相反的意思，可以猜测sucking是“用力吸”的意思。

It's such a common event that you probably never asked yourself why you sleep. __36__ In fact, for sleep researchers, it's one of the biggest unanswered questions in the field.
Stop and think about it for a second. Why should we sleep？__37__ But we sleep every night, even when we have had plenty of rest. There are，no doubt，several different answers to this question, but let's just consider one general purpose of sleep: __38__ Human beings are creatures that are normally active during daylight hours, when our senses fun_ction most effectively. __39__ We can't see objects well, our color vision is entirely lost, and we don't have the smelling or hearing sharpness of other animals. So it actually does make sense to have us stay where we are during the dangerous period when night－waking animals are walking here and there. And one sure way to make sure we don't fall down everywhere and get lost or eaten is to have us not move for seven or eight hours, rising again only when the light is back and our survival chances are better.
It's not the only reason we sleep. __40__Perhaps even the most important one.
A. Is it because we get tired?
B．Should that put human beings in a terrible situation?
C．But from a scientific point of view, this is far from an ordinary matter.
D．But in terms of evolution, it may have been one of the first reasons.
E．Furthermore, if you were designing an animal, would you have it come into long periods of unconsciousness every twenty－four hours?
F．Sleep as a survival approach.
G．At night, humans do rather poorly.

第Ⅱ卷(非选择题)
第二节 (共10小题；每小题 1.5分，满分15分)
阅读下面材料，在空白处填入适当的内容(不多于1个单词)或括号内单词的正确形式。
A man bought a donkey at the market one day and took him home on approval. Now the man owned several donkeys already and he knew each one's character very well.
One of the donkeys was very strong and brave. Another was eager to please people by working quickly but soon got exhausted. One donkey was very lazy. He hated going to work in the morning and he did as little as he __61__(possible) could all day long. He always tried to be the last __62__ the other animals were being loaded up so that he would get the __63__(light) load.
The man led the new donkey into the yard. For a moment he stood __64__(sniff) at his new companions. Then, without hesitation, he came up to the lazy donkey and began feeding comfortably at __65__ side.
__66__ it was late in the day, the man immediately led the new donkey out of the yard, straight back to the market.
“You cannot have given him __67__ fair trial yet，” said the merchant. “It is only ten minutes since you __68__(buy) him.”
“I don't need to try him any more，” replied the man. “I know just __69__ he is like from the friend __70__ he chose for himself. Take him away and give me my money back. I can do without donkeys like him.”
61．______ 62.______ 63.______ 64.______ 65.______
66．______ 67.______ 68.______ 69.______ 70.______
答案：
文章大意：本文是一个小故事，讲的是一个人从一头驴所交的朋友知道驴的本性。
61．possibly 考查词形转换。空处修饰句子的谓语动词could(do sth.)，因此用possible的副词形式possibly。
62．when 考查状语从句。空处引导时间状语从句，用when。
63．lightest 考查形容词最高级。这头驴很懒惰，再根据空前的“the”可知，应用最高级lightest“最轻的”修饰load。
64．sniffing 考查非谓语动词。空处是stood的伴随状语，sniff与he为逻辑上的主谓关系，故用其现在分词形式。
65．his 考查代词。空处指的是the lazy donkey's，故用his。
66．Though/Although 考查状语从句。it was late in the day与the man immediately led the new donkey out of the yard为让步关系。
67．a 考查冠词。trial“试用”在此处为可数名词，其前应用不定冠词a，此处是指“你还没给它一个公平的试用呢”。
68．bought 考查时态。根据上下文时态可知，此处应用一般过去时。
69．what 考查宾语从句。空处引导宾语从句，从句中like后面缺宾语，因此用what。
70．that/who/whom 考查定语从句。空处引导定语从句且在从句中作宾语，从句修饰先行词the friend，故用that/who/whom。

Recently, Robert Whiting, an elderly gentleman with 83, arrived in Paris by plane. At customs, he took a fey minute to look for his passport. “You had been to France before, sir ？” the customs officer asked joking. Mr. Whitint admitted to that he had been to France previously. “Then you should know enough to have my passport ready.” The American said, “The last time I was here, I didn't have to show them.” “Impossible.

答案：
The aim of the experiment is to move the shell from an egg without breaking the egg.
To do the experiment, you need to prepare the following things: a glass, a small saucepan, water, an egg and about 250 ml vinegar. When all these things are ready, you can begin the experiment.
First, boil the egg for about 15 minutes in the saucepan full of water. Next, put the egg into the glass and cover it with the vinegar. After that, leave the egg in the vinegar for 24 hours.
24 hours later, you can see the shell disappear completely. So we can draw the conclusion that the egg shell disappears because it is made of calcium carbonate and the vinegar is an acid. The two substances react to form the gas—carbon dioxide.
