At first I couldn’t believe it! My parents sent me to his school.

There were no desks in rows; no bells rang; no one had to go to class. Although we all lived ―in‖, made us go to bed at a certain time; there was no ―light out‖.

The 2 thing was that practically all the students went to class, and very few people stayed up late at night. Only the new people stayed up or class. The new ones always went wild at first, but this never lasted long. The 4 took some getting used to. Our teachers treated us like ― stand up‖, ―sit down‖ or ―speak out‖. I don’t know of one student who didn’t try his best.

The subjects were the same as those in 6 school, but what a difference in the approach! For example, in botany we had classes in the spring or fall, but instead we two gardens, a vegetable garden and a flower garden. Then, in winter we each studied a few 9 things about what we had grown. In 10 the students built three different kinds of storerooms --- small ones of course, but usable. They did this instead of having lessons in the classroom. They really had a 11 time too, designing everything, drawing the blueprints, the angles and so on. I didn’t take maths. I can’t stand it! Besides, I could do the basic things with numbers. That’s enough.

On the whole I think I am a 13 person for having gone to this school. I can read and write as well as anyone else of my age, and I can think better. That’s probably a real big between the free school and the regular school --- the amount of .

阅读下面短文，按照句子结构的语法性和上下文连贯的要求，在空格处填入一个适当的词或使用括号中词语的正确形式填空，并将答案填写在答题卡标号为16—25的相应位置上。

Chuck’s Friend

In the movie Cast Away, Tom Hanks plays a man 16 (name) Chuck Noland. Chuck is a businessman. One day Chuck is on a flight across the Pacific Ocean suddenly his plane crashes. Chuck (survive) the crash and lands on a deserted island.

On the island, Chuck has to learn to survive all alone. Perhaps the 19 (difficult) challenge is how to survive without friends. In order to survive, Chuck develops a friendship with 20 unusual friend – a volleyball he calls Wilson.

Chuck learns a lot about himself when he is alone on the island. He realizes that he hasn’t been a very good friend because he has always been thinking about himself. During his five years on the island, Chuck learns how 21 (be) a good friend to Wilson. Even though Wilson is just a volleyball, he becomes fond of him. He talks to him and treats him a friend. Chuck learns that we need friends to share happiness and sorrow, and that it is important to have someone to care about. He also learns that he should have cared more about 23 friends.

A volleyball is certainly an unusual friend. Most of our friends are human beings, 24 we also make friends with animals and even things. For example, many of us have pets, and we all have favorite objects such as a lucky pen or a diary. The lesson we can learn from Chuck and all the others 25 have unusual friends is that friends are teachers.

Ⅱ 阅读（共两节，满分50分）

第一节 阅读理解（共20小题；每小题2分，满分40分）

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。

A

Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．

Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．

By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （肾上腺素）, considered to cause stress, which is known to be deadly．Group C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．

―The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,‖ said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．

―Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,‖ Berk said in a statement this week．

26．Why did the scientists carry on the new research?

A．To find out if laughter was good to health． B．To discover the best medicine to cure diabetes．

C．Because the number of diabetic patients is the largest in the world．

D．Because diabetic patients need more laughter than other patients．

27．After 12 months into the study, ___________．

A．C-reactive proteins increase 66 percent in Group C B．the level of the hormones epinephrine stays the same in both groups C．the level of the hormones epinephrine has dropped

D．C-reactive proteins reduced 66 percent in Group L

28．The underlined part ―HDL cholesterol‖ in Paragraph 3 must be _______．

A．something bad to our health B．something good to our health

C．a kind of wonderful medicine D．a kind of dangerous disease

29．In what way does laughter benefit people’s health?

A．Blood is made thick by laughter． B．Laughter makes blood vessels thin．

C．Laughter increases blood pressure．D．Laughter makes blood flow fast．

30．According to Berk, we should _________．

A．choose lifestyles carefully C．prevent our lifestyles in advance B．change our lifestyles D．pay less attention to the positive emotion

B

For centuries, the body’s blood has been linked closely with the emotions．People who show no human emotions or feelings, are said to be cold-blooded killer．For example, the police are searching for a cold-blooded killer．He seems to kill for no reason, and no emotion, as if taking someone’s life as nothing．

Cold can affect other parts of the body．The expression ―get cold feet‖ has nothing to do with cold or your feet．The expression means being afraid to do something you have decided to do．For example, you agree to be president of an organization．But then you learn that all the

other officers have resigned, and all the work of the organization will be your responsibility．You are likely to get cold feet about being president when you understand the situation.

The expression ―give someone the cold shoulder‖ probably comes from the physical act of turning your back toward someone, instead of speaking to him face to face．You may give a cold shoulder to a friend who has not kept a promise he made to you．Or, to someone who has lied about you to others．

A cold fish is not a fish．It is a person．But it is a person who is unfriendly, unemotional and shows no love or warmth．A cold fish does not offer much of himself to anyone．Someone who is a cold fish could be cold-hearted．Now a cold-hearted person is someone who has no sympathy．Several popular songs in recent years were about cold-hearted men or cold-hearted women who, without feelings, broke the hearts of their lovers．

Out in the cold means not getting something that everybody else got．A person might say that everybody but him got a pay raise---he was left out in the cold．And it is not a pleasant place to be．

31．There are _________ expressions related to cold that are mentioned in the passage．

A．3 B．4 C．6 D．7

32．When you refuse to speak to a man and treat him in a distant way, you may express by

―_________‖．

A．I give him the cold shoulder B．I think he is a cold-blooded man

C．I think he is a cold fish D．I’m likely to get cold feet

33．If Sue shows absolutely no reaction to those awful pictures of starving children in Africa,

you will say _________．

A．she is a cold-blooded killer C．she is a cold fish B．she gets cold feet D．she is out in the cold

34．We can use the expression ―__________‖ to describe a man who abandons or hurts his

lover without mercy．

A．cold-blooded B．cold shoulder

C．cold feet D．cold-hearted 35．The topic of this passage is about _________． A．the relationship between cold and our body B．some expressions about friendship C．some expressions connected with cold D．how cold weather comes into being

C

Everyone has a moment in history, which belongs particularly to him. It is the moment when his emotions achieve their most powerful sway over him, and afterward when you say to this person ―the world today‖ or ―life‖ or ―reality‖ he will assume that you mean this moment, even

if it is fifty years past. The world, through his unleashed(释放的) emotions, imprinted itself upon him, and he carries the stamp of that passing moment forever.

For me, this moment—four years in a moment in history—was the war. The war was and is reality for me. I still instinctively live and think in its atmosphere. These are some of its characteristics: Franklin Delano Roosevelt is the president of the United States, and he always has been. The other two permanent world leaders are Winston Churchill and Joseph Stalin. America is not, never has been, and never will be what the song and poems call it, a land of plenty. Nylon, meat, gasoline, and steel are rare. There are too many jobs and not enough workers. Money is very easy to earn but rather hard to spend, because there isn’t very much to buy. The war will always be fought very far from America, and it will never end.

Sixteen is the key and crucial and natural age for a human being to be, and people of all other ages are ranged in an orderly manner ahead of and behind you as a harmonious setting for the sixteen-year-olds of the world. When you are sixteen, adults are slightly impressed and almost threatened by you. This is a puzzle finally solved by the realization that they foresee your military future: fighting for them. You do not foresee it. To waste anything in America is immoral. String and tinfoil are treasures. Newspapers are always crowed with strange maps and names of towns, and every few months the earth seems to lurch（突然倾斜）from its path when you see something in the newspapers, such as the time Mussolini, who almost seemed one of the permanent leaders, is photographed hanging upside down on a meat hook.

36. Which statement best tells the main idea of the first paragraph?

A. Reality is what you make of it.

B. Time is like a river.

C. Emotions are powerful.

D. Every person has a special moment.

37. The author still clearly remembers the war because________.

A. Franklin Delano Roosevelt was President.

B. It was his personal reality and part of his life.

C. There was not much to buy.

D. The war would never end.

38. What were the author’s feelings about the war?

A. It was ever real for him, yet he was not actively involved.

B. It was real for him because he was a soldier at that time.

C. It was very unreal to him.

D. The war was very destructive to the people at home.

39. Why does the author think that adults are impressed with sixteen-year-olds?

A. Adults would like to be young.

B. Sixteen-year-olds do not waste things.

C. Sixteen-year-olds read newspapers.

D. They will be fighting soon for adults.

在m碰撞M的过程中，由动量守恒定律得：mv－Mv1 = 0，

代入m、M解得v1=1.5m/s ΔE=mv－Mv1=1.31J 22

（2）假设m′最终能与M一起运动，由动量守恒定律得：

Mv1=（M+m′）v2 代入m′、M解得v2 = 0.9375m/s

m′以v2=0.83m/s速度运动时受到的向上洛仑兹力

f = BQv2=5.625N＞m/g=3N

所以m′在还未到v2=0.9375m/s时已与M分开了。由上面分析可知当m′的速度为v3=3/（0.3×20）=0.5m/s时便与M分开了，根据动量守恒定律可得方程：

Mv1 = Mv2/+m/v3 解得v2/=1.2m/s

2014-2015学年广东省东莞市万江中学高三(上)第一次月考物理试卷

2014-2015学年广东省东莞市万江中学高三（上）第一次月考物

理试卷

一、单项选择题：本大题共4小题，每小题4分，共16分．在每小题给出的四个选项中，只有一个选项符合题目要求，选对的得4分，选错或不答的得0分．

1．（4分）（2014秋•长兴县校级期末）孔明灯相传是由三国时的诸葛孔明发明的，如图所示，有一盏质量为m的孔明灯升空后沿着东偏北方向匀速上升，则此时孔明灯所受空气的作用力的大小和方向是（ ）

A． 0 B． mg，竖直向上

C． mg，东北偏上方向 D．

mg，东北偏上方向

考点： 共点力平衡的条件及其应用；力的合成与分解的运用．

专题： 共点力作用下物体平衡专题．

分析： 孔明灯做匀速运动，加速度为零，合力为零；只受重力和空气的作用力，根据平衡条件得到空气的作用力的大小和方向．

解答： 解：孔明灯升空后向着东北偏上方向匀速直线运动，加速度为零，合力为零； 只受重力和空气的作用力，根据平衡条件得到空气的作用力的大小为mg，方向竖直向上； 故选：B．

点评： 本题关键是明确孔明灯的运动情况，得到加速度后进一步确定受力情况，基础题．

2．（4分）（2015•陕西校级三模）一质点沿x轴做直线运动，其v﹣t图象如图所示．质点在t=0时位于x=5m处，开始沿x轴正向运动．当t=8s时，质点在x轴上的位置为（ ）

A．

x=14m

考点： 匀变速直线运动的图像．

专题： 运动学中的图像专题．

x=3m B． x=8m C． x=9m D．{东莞市万江中学高一语文作业}.

分析： 速度时间图象可读出速度的大小和方向，根据速度图象可分析物体的运动情况，确定何时物体离原点最远．图象的“面积”大小等于位移大小，图象在时间轴上方“面积”表示的位移为正，图象在时间轴下方“面积”表示的位移为负．

解答： 解：图象的“面积”大小等于位移大小，图象在时间轴上方“面积”表示的位移为正，图象在时间轴下方“面积”表示的位移为负，

故8s时位移为：s=，由于质点在t=0时位于x=5m处，故当t=8s时，质点在x轴上的位置为8m，故ACD错误，B正确．

故选：B．

点评： 本题抓住速度图象的“面积”等于位移是关键．能根据图象分析物体的运动情况，通过训练，培养基本的读图能力．

3．（4分）（2014•重庆）以不同初速度将两个物体同时竖直向上抛出并开始计时，一个物体所受空气阻力可忽略，另一物体所受空气阻力大小与物体速率成正比，下列用虚线和实线描述两物体运动的v﹣t图象可能正确的是（ ）
