We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn’t good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people’s health.
Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers.
During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice.
Scientists often use mice for research because they have a similar genetic(基因) structure to humans. “Since most substances that are dangerous in mice are also dangerous in people, it’s likely that those physical problems that cause those mice to have increased deaths also work in people,” says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives.
Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation’s sugar desire will provide for a truly sweeter future.
1.The study conducted by researchers aimed at learning about________
A. the advantages and disadvantages of sugar

Language is part of our daily lives, no matter where we live in the world. It is the same with music, whether you listen to it on the radio on your drive to work or sit before an orchestra. Both language and music play a huge role in our culture. 1.
Both language and music have a writing system. In English we record language using the alphabet, which is a collection of letters. In the same way, we use notes to keep a record of music. Just as you are reading this collection of letters on the screen and find meaning in it, musicians read notes and create meaning in the form of music which we can hear.2. By writing pieces of text or music, we are able to share experiences through time. I can read the ideas or hear the composition of someone who lived hundreds of year ago, which is really quite exciting.
3. You can make a good guess at where someone is from by listening to the language they use. In the same way, we know that styles of music are different around the world, giving us the opportunity to explore many different cultures through their music and providing us with music for every situation.4. Even if you don’t like Britpop melodies, you may love the energy of Latin American salsa music.
Both share emotion. How do you know that I am angry? Of course you may be able to see it in my face, but you will know for sure through my words.5. Music can show you exactly how the composer was or is feeling, and allows us to share in that emotion. When you feel happy, you might want to sing and dance to a happy song to celebrate your happiness. In contrast, you have probably also listened to sad music when you were feeling down. I think we have all used music to express or process our emotions, often combining it with language in the form of song lyrics.
A. Both vary with culture.
B. Here are some of their similarities.
C. They have some distinguishing characteristics.
D. So just as you read English, you can read music.
E. Similarly, music can sound angry, sad or happy.
F. This also means that there is something for everyone!

The world we live in is becoming increasingly complex and uncertain. And with it, the conventional thinking of yesterday is no longer sufficient. Creating real breakthrough opportunities requires a fundamental change in our thinking. As Einstein said, "We can't solve problems by using the same kind of thinking we used when we created them.”
There's no better example of this than the myth of the four-minute mile.
For centuries, runners had been attempting to run a mile in under four minutes. In the 1950s, the attempt to break the barrier took on renewed importance, and a number of famous runners publicly and unsuccessfully attempted the challenge. Many of the newspapers of the day began to question whether humans would ever be able to run a sub-four-minute mile. Then, in 1954, a man named Roger Bannister did the unthinkable. He broke through the imaginary barrier, running the mile in 3 minutes and 59.4 seconds. It was an amazing achievement.
But here's what's really interesting: it was only forty-six days later that another runner broke Bannister's record. And the following year, two new runners broke the four-minute mark in the same race. Dozens followed, and as of this writing, more than 1,400 runners have accomplished the goal, including one runner who ran two miles in less than eight minutes.
Did something change with respect to human body, track conditions, weather patterns, running shoes, or the human diet between the start of Bannister's race and the few years that followed? No. So what explains the sudden and dramatic explosion of athletic achievement?
The myth's unimaginable power over runners had lifted. What Bunnister had done was not just break the four — minute — mile barrier; he shattered(粉碎)the myth that created the barrier in the first place. This paradigm (榜样)had offered a set of actions available for runners to take. Runners were really free to run through the invented boundary.
Creating breakthroughs requires shattering the myths that limit our imagination and lock us into conventional thinking. Think about your own situation. What myths are you stuck in? And what would be possible if you had the courage to challenge the myths?
1.What is needed to create breakthroughs?
A.Conventional thinking. B.Changes in our thinking.
C.Complex situation. D.Einstein's encouragement.
2.What was the real barrier that kept runners succeeding in the four-minute mile?
A.The belief that it was unachievable.
B.Lack of professional training.
C.The poor track conditions.
D.Lack of sufficient diet.
3.The example of Roger Bannister is used to .
A.list a new record in the race B.prove newspapers are wrong
C.show barrier can be broken D.call on us to learn from him
4.What does the writer try to explain in Paragraph 6?
A.The power of the myth.
B.The achievements of Bannister.
C.The importance of running freely.
D.The significance of breaking barriers.
5.What is the best title of the passage?
A.Creating Breakthroughs B.Accepting the Myths
C.Locking Your Imagination D.Becoming the Best Athlete

Most of us spend our lives seeking the natural world. We go fishing,sit in the garden,have a picnic,live in the suburbs or go to the seaside.The most popular leisure activity in Britain is going for a walk.When joggers jog,they don’t run the streets.Every one of them tend to go to the park or the river.
But despite this,our children are growing up nature deprived(剥夺).I spent my boyhood climbing trees.These days,children are robbed of these ancient freedoms,due to problems like crime,traffic,the loss of the open spaces and strange new ideas about what is best for children,that is to say,things that can be bought,rather than things that can be found.
The truth is to be found elsewhere.A study in the US: families had moved to better housing and the children were assessed for ADHD—attention deficit hyperactivity disorder(多动症).Those whose accommodation had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.
ADHD is one of the great problems of modern childhood. One study after another indicates that contact with nature gives huge benefits to ADHD children.However,we spend money on drugs rather than on green places.
The life of old people is measurably better when they have access to nature.The increasing concern for the growing population of old people is in quality rather than quantity of years.And study after study finds that a garden is the single most important thing in finding that quality.Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.

Fixed or growth mindset — which do you have?
We live in an uncertain world with all the technological advances we are experiencing, which meanse is a requirement for a change in midset (思维模式). In order to be on top of our game both personally and organizationally, we need to develop a growth mindset.
A fixed mindset supposes that you have native abilities and are naturally clever or skilled in certain areas of life. When you receive infonnation about how you have performed in a test or set of tasks t you may worry about how you are judged. Our parents probably said to us when we were young,"Since you scored really well in the test, you must be clever." However, by being repeatedly told “You arc clever” or “You are really ga*al al your job”,a person’s self-respect is actually dainagcd.
The growlh - mindest persona view life as a series of exciting challenges and want t o constantly learn. Brain activity occurs in this mindset when they receive information about what they could do belter or improve. They do not view their abilities as fixed or us failure. Learning is king and the more they practice , the more they know they will succeed.
What is important is giving praise around process and not around ability. For example , instead of saying"Since you got a great score, you must be clever" f say " You got a great score, and you must have tried really hard". This creates challenge in indivicluats and
The meaning of mindsets is massive for business. Fixed-mindset managers are not fans of giving feedback (反馈). They do not want to stretch themselves or others because they fear failure. Therefore their business may stand still because there is no risk or innovation (创新) occurring.
Listen from your own fixed mindset 一 for example ," I can't do that” 一 and answer with a growth-mindset response 一 “I can't do that yet!" Remember there is no such thing as failure and there is s only learning. If you don't fail occasionally ,you will never learn to change and grow.

A. A growth mindstet means no failure.
B. People need develop a fixed mindset.
C. A fixed mindset focuses more on process.
D. People should develop a growth mindest.
2.Which judgment seems more encouraging?
A. You are clever.
B. You are skillful.
C. You have worked hard.
D. You arc great at your job.
3.What do the growth-mindset persons most advocate?
A. Keeping on learning.
B. Viewing ability as failure.
C. Giving praise around ability.
D. Learning from the fixed mindset.
4.What is the main idea of the last paragraph?
A. Always stay in ihe same mindset
B. Think and act in different mindsets.
