Researchers have found more evidence that suggests a relationship between races and rates(率) of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos.
Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2.000 people in the study developed lung cancer.
Researchers say genetics(遗传学) might help explain the racial and ethnic(种族的) differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference.
African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer.
Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted(针对) medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine."
小题1:Which of the following orders is from higher to lower risk of having lung cancer?
A.Whites—Native HawaiiansB.Africans—Americans—Latinos
C.Asians—Native HawaiiansD.Africans—Americans—Native Hawaiians
小题2:Researchers agree that it is      that may probably determine black people’s risk of lung cancer.
A.the larger amount of smoking than white people
B.the living style or habit of the blacks
C.the depth of cigarette smoke into their lungs
D.the physical strength to react to cigarette smoke
小题3:People in the new study are made up of          .
A.heavy smokers in AmericaB.the black and white people
C.the Asians and HawaiiansD.smokers and non-smokers
小题4:The production of BiDil referred to in the last paragraph is to      .
A.explain different races react to some diseases differently
B.tell the readers that racial differences exist in smokers
C.show a big step people have taken in the medicine area
D.support the idea that it is easy for blacks to have cancers

The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s interruption of our thoughts.
We have already entered a golden age of little white lies about our cellphones, and this is in generally a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach.
The concept of being unreachable is not new – we have “Do Not Disturb” signs on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while?
The problem is that we come from a long-established tradition of difficulty with distance communication. Until the recent mass use of cellphones, it was easy to communicate with someone next to us or a few feet away, but difficult with someone across town, the country or the globe. We came to take it for granted.
But cellphones make long-distance communication common, and endanger our time by ourselves. Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees, myself usually included, can’t help at times wanting to throw their phones away, or curse this invention.
But we don’t and won’t, and there really is no need. That we have the right to take back our private time is a general social recognition.
In other words, we don’t have to pay too much attention to the rings of our own phones. Given the ease of making and receiving cellphone calls, if we don’t talk to the caller right now, we surely will shortly later.
A cellphone call deserves no more importance than a word from the person next to us. Though the call on my cellphone may be the one-in-a-million from Steven Spielberg–who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off, thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch.

小题1:.
What does the writer think about people telling “white lies” about their cellphones?
A.It is a way to show that you don’t like the caller.
B.It is natural to tell lies about small things.
C.It is basically a good way to protect one’s privacy.
D.We should feel guilty when we can’t tell the truth.
小题2:.
What is the meaning of the underlined word “devotees” in Paragraph 5?
A.people who enjoy something. B.people who are bothered.
C.people who hate something.D.people who are interrupted.
小题3:.
. According to the author, what is the most annoying problem caused by cellphones?
A.People are always thinking of the cellphone rings so that they fail to notice anything else.
B.Cellphones interrupt people’s private time.
C.People feel guilty when they are not able to answer their cellphones.
D.With cellphones it is no longer possible to be unreachable.
小题4:.
. What does the last paragraph suggest?
A.A person who calls us from afar deserves more of our attention.
B.Steven Spielberg once called the author to talk about the author’s novel.
C.You should always finish your lunch before you answer a call on the cellphone.
D.Never let cellphones disturb your life too much.

There are two kinds of physical activity which require special training. The first demands exact, careful movements of the muscles(肌肉).This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead to a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of a given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.
小题1:.  The first kind of physical activity must be strictly controlled because ______.
A.a mistake in the wrong direction is dangerous to the fingers
B.a wrong movement in a direction will cause no mistakes
C.a movement in the wrong direction will cause a mistake
D.a slight movement of a finger will lead to a mistake
小题2:.            
What must a dancer do before she can balance herself?
A.she must dance on the point of her shoesB.she must receive long-time training
C.she must turn around on one footD.she must perform again and again
小题3:.            
The experiments done by some scientists showed that __________.
A.some male patients were asked to ride bicycles regularly in the experimentsB.the physical exercise had more harmful effect on the hearts of the untrained patients
C.the physical exercise was harmless to the male patients with heart trouble
D.the physical exercise could be helpful for the patients to take in more oxygen
小题4:. What would be the best title for this text?
A.Training Our BodiesB.Physical Activities
C.Movement TrainingD.Extra Body Effort

Terraforming (Earth-forming) other planets, also known as planetary engineering (行星工程), seems like a task still centuries away for mankind to accomplish. However, it is a vigorous topic that attracts both popular and scientific interest. Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it’s a good idea?
Mankind is getting more and more hard facts about other planets. The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury, Jupiter and Saturn have been studied by spacecraft. Speculations have been answered; new questions have been raised, and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.
In the past, people with excellent ideas about terraforming have kept them to themselves, or buried them in a desk drawer because they did not realize that anyone else was interested. But now, a wide circle of people has begun to do this kind of work. For instance, NASA funded a project on transforming Mars.
There are several strong reasons which demand that the possibilities of terraforming be studied carefully. First, it’s an exciting idea of a possible future for human beings. Such thinking has a valuable role in providing options for our future directions. Secondly, the techniques of terraforming will also help contemporary technologies in weather and climate control. Thirdly, such study may assist us in detecting any possible existence of extraterrestrial intelligence (SETI, The Search for Extraterrestrial Intelligence, 地外文明搜索) and alien (异己的) civilizations on other planets.
Though the mission is far beyond our reach at the moment, we should at least keep our options open. Through debate and study on this subject, the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.
小题1:.
. According to the context, what’s the meaning of the word “speculation” in paragraph 2?
A.The act of discussing something with a group of people.
B.The act of studying and researching.
C.The act of guessing without knowing all the facts about something.
D.The acting of writing letters to a certain organization.
小题2:.
Why did people keep the idea of terraforming to themselves in the past?
A.They thought no one else would show interest in the idea.
B.They gradually came to find the idea crazy.
C.They thought the idea would never come true.
D.They had few resources for further study on this topic.
小题3:.
. Which is NOT the reason to support the study of terraforming?
A.Even if we don’t succeed in terraforming, such study may help us to better understand technologies such as climate and weather control.
B.Such study may explore a new direction of development for human beings.
C.Such study may enable us to find the lives on other planets.
D.As the resources on Earth are being drained, it’s very urgent to study how to migrate (迁移) to other planets。
小题4:.
What’s the main idea of the article?
A.It’s highly possible that terraforming other planets will come true so we should increase investing in this program.
B.Even if the idea of terraforming other planets may take centuries to realize, we have many reasons to support such studies.
C.Terraforming other planets is the best option for human being’s future.
D.More and more people are taking planetary engineering as their occupation.

In white shirt, blue pants, black cloth shoes and two pigtails (辫子), Jingqiu gives off an air of great “pure beauty” in Zhang Yimou’s new movie Under the Hawthom Tree.《山揸树之恋》
The film tells the story of the sad romance of Jingqiu and a handsome young man named Laosan. Set at the end of the “cultural revolution” (1966-1976), the pair manage to fall in love although they come form different political environments.
Before it was released, moviegoers speculated (推测) on just what this “pure beauty” could be. Director Zhang complained of how long it had taken him to find the right girl for the part of Jingqiu—a character so innocent that she believes simply lying on the same bed with a man will make her pregnant.
It was 18-year-old Zhou Dongyu who stood out from the crowd. According to Zhang, Zhou has “eyes that are clear like a fountain on a mountainside”. Born of an ordinary worker’s family, the Shijiazhuang girl was in her final year of high school and working hard for a place in an art college.
While some teenagers consider such “pure beauty” illusory (虚幻的), others believe that it speaks of something soulful.
Purity is all about the innocence that shines through from within, thinks 16-year-old Tan Mengxi of Nanjing.
“Being pure can be simple, not having complicated thoughts and being inexperienced. However, it doesn’t mean an ignorant or naive (天真的) person. So, a person is pure in his or her nature if he or she is always enthusiastic and able to deal with difficult matters independently. This purity doesn’t pass with time,” she said.
小题1: What image does Jingqiu give to audiences in the movie Under the Hawthorn Tree?
A.A simple girl.B.A pure girl.C.A romantic girl.D.A silent girl.
小题2: What kind of girl looks pure according to the passage?
A.A girl in red shirt, blue pants, black leather shoes and two pigtails.
B.A girl has eyes that are clear like a fountain on a mountainside.
C.A girl who was born into an ordinary worker’s family.
D.A girl wears accessories and make-up.
小题3: What’s the opinion of Tan Mengxi about purity?
A.It is of whether someone is ignorant or naive.
B.Being pure can be simple, not having complicated thoughts and being inexperienced.
C.It is of whether someone is always enthusiastic.
D.Purity is a matter of internal quality and doesn’t pass with time.
小题4: Which do you think is the best title for the passage?
A.What makes a pure girl?
B.A debate on the movie Under the Hawthorn Tree
C.Opinions on the character Jingqiu
D.It’s hard to find the character Jingqiu

Inaugural Address-John F. Kennedy
delivered 20 January 1961
We observe today not a victory of party, but a celebration of freedom—symbolizing an end, as well as a beginning—signifying renewal, as well as change. For I have sworn before you and Almighty God the same solemn oath our forebears prescribed nearly a century and three-quarters ago.
The world is very different now, for man holds in his mortal hands the power to abolish all forms of human poverty and all forms of human life. And yet the same revolutionary beliefs for which our forebears fought are still at issue around the globe–the belief that the rights of man come not from the generosity of the state, but from the hand of God.
We dare not forget today that we are the heirs of that first revolution. Let the word go forth from this time and place, to friend and foe alike, that the torch has been passed to a new generation of Americans—born in this century, tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage, and unwilling to witness or permit the slow undoing of those human rights to which this nation has always been committed, and to which we are committed today at home and around the world.
Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, to assure the survival and the success of liberty.
This much we pledge—and more…
In the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. I do not shrink from this responsibility -- I welcome it. I do not believe that any of us would exchange places with any other people or any other generation. The energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve it. And the glow from that fire can truly light the world.
And so, my fellow Americans, ask not what your country can do for you; ask what you can do for your country.
My fellow citizens of the world, ask not what America will do for you, but what together we can do for the freedom of man.
Finally, whether you are citizens of America or citizens of the world, ask of us here the same high standards of strength and sacrifice which we ask of you. With a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking His blessing and His help, but knowing that here on earth God's work must truly be our own.
小题1:
What should friends and foes know?
A.That the United States is powerful.
B.That a new generation of Americans are responsible for their government.
C.That the United States is governed by liberals.
D.That the rights of man come from the hand of God.
小题2:
What is Kennedy’s promise to the world?
A.To support liberty.B.To abolish all forms of human poverty.
C.To visit each country at least once.D.To support any friend.
小题3:
What should citizens of the world ask of America?
A.How America can help them.
B.If America plans to invade their country.
C.What they can do for freedom.
D.What they can do for America.
小题4:
Which of the following statement is NOT true according to the passage?
A.Human beings have the power to put an end to all forms of poverty.
B.We should remember we are the first revolution.
C.Our nation has always been committed to human rights.
D.We should assure the survival and the success of liberty.

The world is filled with many interesting sounds. Some are very pleasant to hear; others are unpleasant to our ears. In a day, you probably hear hundreds of different sounds.
All sounds are different. Some may be soft; others may be loud. Some sounds are high; others are low.
Some sounds are useful. Without sound we cannot talk or listen to one another. The ringing alarm clock (闹钟)makes people wake up. The hooting of a horn (喇叭声) on the road warns careless people of danger.
We make sounds by making things move to and fro(来回地). This to-and-fro movement is called vibration (振动). It means moving up and down or forwards(向前地) and backwards(向后的) very fast. This makes sound waves(波).
We can make sounds in many ways, for example, by shouting, clapping our hands and striking the table. We can make sounds only by making things vibrate. We can talk because we can make our vocal cords (声带) vibrate. Our vocal cords are in a sound box or voice box. Two vocal cords vibrate when our lungs(肺) force the air through them.
小题1:We can make sounds ______.
A.by making things still
B.by making things vibrate
C.by making things jump up and down
D.by changing the positions of things
小题2: Some sounds are useful because ______.
A.they can wake people up
B.they can warn people to be careful when they are crossing the road
