Teenagers who spend hours in front of the television may have a poorer diet as young adults.
A study,which included nearly 1,400 high school students,found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人)five years later. Why does this happen? Should the parents take any measures?
On the one hand,people who spend a lot of time in front of the TV, especially teenagers,may snack more,and that may affect their long-term diet quality.
On the other hand,TV ads for fast food,sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.
Lead researcher Dr. Daheia J. Barr-Anderson,of the University of Minnesota in Minneapolis,told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food , those who'd watched less than two hours per day had the highest intake(吸收)of fruits,vegetables, whole grains and high-calcium food. In her opinion,parents should limit and monitor TV viewing.
As far as I am concerned,children should watch no more than two hours of television per day. And parents should set a good example by eating right,being physically active and curbing their own TV time.
What's the best title for this passage?

A.People should keep away from TV to keep healthy.
B.Teenagers' TV time may affect their diets later.
C.Why do teenagers like TV"
D.Parents' own habits may affect children later.

Science Fiction
The science fiction type of entertainment is considered by most to be fathered by Jules Verne (A Journey to the Center of the Earth and Twenty Thousand Leagues Under the Sea) and H. G. Wells (The Time Machine and The War of the Worlds). Sci-Fi, as it is commonly shortened, is a fictional story in which science and technology have a significant influence on the characters and plot. Many such works are guesswork about what the future holds and how scientific findings and technological advances will shape humankind.
Writing in the late 1800s, Jules Verne was remarkably successful in his 10 guesses about future technologies of air conditioning, automobiles, the Internet, television, and underwater, air, and space travel. Unbelievably, of all places from which to choose, Jules Verne guessed Tampa, Florida, USA as the launching site of the first project to the Moon, which was only 200 kilometers away from the actual 1969 location at Cape Canaveral, Florida.
One of the best-known science fiction books is Nineteen Eighty-Four by George Orwell. Published in 1949, it was not meant as a prediction, but as a warning: Orwell was describing what he saw as the outcome of the ideas, trends, and emerging technologies of his time. Many invented terms from this novel have become common in everyday use, such as “big brother” and “doublethink”. Even the author’s name has been made into an adjective—Orwellian—and has become a warning descriptor for situations where privacy is lost and the individual becomes sacrifice under a totalitarian(极权主义) government. Nineteen Eighty-Four was translated into sixty-five languages within five years of its publication, setting a record that still stands.
What helps bring science fiction into being is usually a new discovery or innovation. The author creates an analysis of the potential influence and consequences and then wraps it in a pleasant story. For example, the beginning of space exploration was followed a few years later by the Star Trek television program and movie series. Advances in genetics(遗传学) cause fantasies of the end of disease, horrors of eugenics(优生学), and thrillers where creatures disappearing long ago are brought back to life. The science fiction author’s self-determined role is that of field glasses for humanity—searching the world of future possibilities upon the road which we are traveling.
What can science fiction offer to people?

A.A forecast of how a new discovery could influence mankind.
B.A thoughtful look at the present drawbacks of technology.
C.An analysis of why a new technology could be used to harm human.
D.A thoughtful look at the past and what brought us to this point in history.

Which of the following best summarizes the description of Nineteen Eighty-Four?

A.A prediction of future technologies.
B.A warning of cruel and unfair ruling.
C.The consequence of scientific findings.
D.An imaginary perfect world of freedom.

From the passage we can learn that _____.

A.Nineteen Eighty-Four adopted some popular terms
B.H.G. Wells predicted the Internet in the late 1800s
C.Cape Canaveral was mentioned in Jules Verne’s fiction
D.Star Trek movie series were based on space exploration

According to the author, what is the role of science fiction in society?

A.A moral compass.
B.A reference of technology.
C.A record of science development.
D.A consideration of possibilities.

Does money buy happiness? Not! Ah, but would a little more money make us a little happier? Many of us smirk(傻笑,假笑) and nod. There is, we believe, some connection between financial fitness and emotional fulfillment. Three in four American college students—nearly double the 1970 proportion— now consider it “very important” or “essential” that they become “very well off financially”. Money matters.
But a surprising fact of life is that in countries where nearly everyone can afford life’s necessities, increasing wealth matters surprisingly little. The connection between income and happiness is “surprisingly weak,” observed University of Michigan researcher Ronald Inglehart in one 16-nation study of 170,000 people. Once comfortable, more money provides diminishing returns(报酬递减). The second piece of pie, or the second $100,000, never tastes as good as the first. Even lottery winners and the Forbes’ 100 wealthiest Americans surveyed by University of Illinois psychologist Ed Diener have expressed only slightly greater happiness than the average American. Making it big brings temporary joy. But in the long run wealth is like health: its complete absence can create suffering, but having it doesn’t guarantee happiness. Happiness seems less a matter of getting what we want than of wanting what we have.
Has our happiness, however, floated upward with the rising economic tide? Are we happier today than in 1940s, when two out of five homes lacked a shower or tub? Actually, we are not. Since 1957, the number of Americans who say they are “very happy” has declined from 35 to 32 percent. Meanwhile, the divorce rate has doubled, the teen suicide(自杀) rate has increased nearly three times, the violent crime rate has gone up nearly four times, and depression has mushroomed. Economic growth has provided no boost to human morale. When it comes to psychological well being, it is not the economy.
I call this soaring wealth and shrinking spirit “the American paradox.” More than ever, we have big houses and broken homes, high incomes and low confidence, secured rights and reduced civility. We are good at making a living but often fail at making a life. We celebrate our prosperity(繁荣) but long for a purpose. We treasure our freedoms but long for connection. In an age of plenty, we feel spiritual hunger.
Which of the following statements best expresses the author’s view?

A.The more money we earn, the less returns we have.
B.The more money we earn, the happier we would be.
C.In the long run, money cannot guarantee happiness.
D.In the long run, happiness grows with economy.

C.profit brought by it is less than that from the first $100,000
D.happiness brought by it is less than that from the first $100,000

My favorite English teacher could draw humor out of the driest material. It wasn’t forced on us either. He took Samuel Johnson’s dictionary, Addison’s essays, and many other literary wonders from the eighteenth century and made them hilarious, even at eight o’clock in the morning. The thing that amazed me most was that the first time I read these works on my own some of them seemed dead, but the second time, after his explanation, I couldn’t believe that I hadn’t seen the humor. The stories and poems and plays were suddenly filled with allusions(典故) and irony andhilarious moments. I learned more from him than from any other teacher.
My least favorite English teacher also made people laugh. Some students found him to be wonderfully funny. Many others did not. He assigned journals over a six week period, to be written in every day. At the end of the six weeks I had a notebook full of bits and pieces about my ideas, short stories, reactions to what we had read, and so on. Our teacher announced that we would be grading each other’s journals. Mine was passed to Joe, that class clown, who always behaved in a funny or silly way. He saw it fit to make joke of and said, “This writing isn’t fit to line the bottom of a birdcage.” Our teacher laughed at that funny remark. It hurt me so much that the anger from it has driven my writing and teaching ever since.
So what makes the difference? Humor is one of the most powerful tools teachers or writers have. It can build up students and classes and make them excited about literature and writing, or it can tear them apart. It is true that humor is either productive or counter-productive and self-defeating.
The passage mainly discusses _____.

A.teaching B.literature
C.humor D.knowledge

Are you truly happy? Do you ever know what it means to be happy and what it takes to achieve happiness? The following are a few tips that I follow to create happiness in my life.
Make a plan for achieving goals that you believe will make you happy. Your moods will very likely increase if you are going after something you value.
Surround yourself with happy people. It is easy to begin to think negatively(消极地) when you are surrounded by people who think that way.
When something goes wrong, try to figure out a solution instead of being absorbed in self pity. Truly happy people don’t allow setbacks(挫折) to affect their mood because they know that with a little thought they can turn the things back to their favor.
These few minutes will give you the opportunity to focus on the positive things in your life and will lead you to continuous happiness.
Whether you treat yourself to lunch, take a long, relaxing bath or simply spend a few extra minutes on your appearance, you will be subconsciously(下意识地) putting yourself in a better mood.
Finding the humor in situations can also lead to happiness. Find a way to make light of a situation that would otherwise make you happy.
Keeping healthy is another way to achieve happiness.

A.What makes one person happy may be very different from what makes someone else happy.
B.On the contrary, if you are around people who are happy,their emotional state will be easily passed to you.
