We all have our own idea of what the perfect smile should look like, whether we show a mouthful of whites or keep our lips closed and turned up at the corners. When we think of the perfect smile, we often picture someone grinning, with all of our teeth showing, But based on new findings, less is actually more. Nathaniel Helwig and his colleagues at the University of Minnesota discovered that a successful, genuine smile actually rests less on showing teeth and more on facial balance and symmetry(对称).

For the study, researchers looked at 3D computer-animated facial models of more than 800 participants. The computer-animated facial models went through a series of facial transformations, with researchers changing the mouth angle, amount of teeth shown, and the degree of the smile. Participants were then asked to rate the models’ smiles based on effectiveness, genuineness and pleasantness.

The results of the study found that the most successful smile had a perfect balance of teeth, an ideal mouth angle, and a smile length that extended to what was called the “sweet spot.” Smiles that showed a quick sync(同步)of the left and right side of the face during smiling were also more highly related.

Smiling makes up a good part of our nonverbal communication, making it easier to draw people to you and also seem sincere. It’s also worth noting that a perfect smile could help improve your health too.

1.What is the possible meaning of the underlined word “grinning” in the first paragraph?

2.Which aspect should be considered when rating the smiles in the study?

A. How pleasant it makes people feel.

B. Whether it improves health.

C. How successful smiling people are.

D. Whether it lasts long enough.

3.What makes the perfect smile based on the new study?

A. White teeth.　　 B. Smile length.

C. Facial balance.　　 D. Lip corners.

4.Which of the following is TRUE according to the study?

A. A perfect smile has a positive effect on your health.

B. A perfect smile means showing all your teeth.

C. The less you smile, the more you can show.

D. A perfect smile involves only a balance of teeth.

5.Where does this text probably come from?

Behind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On one hand, we assume that we are indestructible. On the other hand, we think that any damage we impose on ourselves can be undone when wβfinally clean up our act.

If the evidence for how wrong the first idea is isn’t apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?

To a surprising degree, the answer is yes. Over the past five years, scientists have collected a wealth of data about what happens when aging people with bad habits decide to turn their lives around.

The heartening conclusion: the body has an amazing ability to heal itself, provided the damage is not too great.

The effects of some bad habits-smoking, in particular-can haunt you for decades. But the damage from other habits can be largely healed.

“Any time you improve your behavior and make lifestyle changes, they make a difference from that point on.”says Dr. Jeffey Koplan.“Maybe not right away. It’s like slamming on the brakes. You do need a certain distance.”

But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research: ---A study concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month. ---The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline ... Adopting healthy habits won’t cure all that bothers you, of course. But doctors believe that many chronic diseases-from high blood pressure to heart disease and even some cancers-can be warded off with a few sensible changes in lifestyle.

Not sure where to start? Surprisingly, it doesn’t matter, since one positive change usually leads to another. Make enough changes, and you'll discover you’ve adopted a new way of life.

1.Most people with bad habits of eating more than they should believe that　　　　　 .

A. their bodies cannot be damaged by the bad habits

The year 2019 saw the end of the hit sitcom The Big Bang Theory. Now, another popular comedy, Modern Family, follows in their footsteps. After 11 seasons the final episode aired on April 8, bringing an end to a sitcom “widely recognized as one of the funniest and most decorated sitcoms of this century”, according to EOnline.

Hitting our screens in 2009, the show claimed 22 Emmys in total, an American award that recognizes excellence in television. At its peak the show attracted over 9 million viewers for its relatable family dynamic, loveable characters and mockumentary (伪纪录片) style. In this format, characters can convey their own thoughts and feelings directly to the audience via a short sit-down interview.

Over the course of the series, fans have witnessed the Pritchett-Dunphy-Tucker clan (家族), an extended Los Angeles family, overcome the trials and tribulations of any modern family, including death, adoption and mental health.

The big family’s highs and lows have made it so relatable that we see them as part of our own family and care about their stories. From fights between siblings (兄弟姐妹) to parental disagreement about children’s education, the show, despite being a comedy, deals with serious modern issues that are familiar to the audience.

Despite its success, showrunners  admitted that the sitcom had been running on fumes (后劲不足的) during the last few seasons. The final episode went as expected, with the growing branches of each family going their separate ways following one giant on-screen embrace involving every cast member.

As the camera cut to each departing family member, Jay Pritchett, the patriarch (大家长) of the family, expressed an important theme of the show. “Life is full of change. I learned a long time ago you can fight it, or you can try to make the best of it. And that’s a whole lot easier if you’ve got people helping you face whatever life throws at you,” he said emotionally.

Just as the final episode concluded, fans were treated to one last heartfelt moment. As each family switched off their porch (门廊) light, Claire asks Phil (a couple in the show) what they’ll do now that their kids have grown up and moved on. Phil said, “Leave the porch light on – they come back,” a subtle (巧妙的) hint that the show might someday return.

3.What does the underlined phrase “trials and tribulations” in Paragraph 3 probably mean?

A.fears B.problems

C.changes D.boundaries

4.What does Modern Family convey to us, according to Jay Pritchett?

A.Parenting and education are important.

B.Fighting is the best way to handle changes.

C.Life will be easier if you are able to get help.

Albert Einstein, the genius behind the theory of relativity, which provided a new framework for all of physics and proposed new concepts of space and time, has recently been making headlines again. However, this time it is not for a new scientific breakthrough, but because of two handwritten notes the scientist gave a bellboy 95 years ago.

The story goes something like this. In October 1922, Einstein was invited to Tokyo to deliver lectures. As the scientist was making his way from Europe to Japan, he received a telegram informing him that he had been awarded the Nobel Prize in Physics. Though pleased at the news, he decided to continue with his Japanese trip instead of heading to Stockholm to accept the honor.

When in Tokyo, he penned two notes in German. One of them, written on a piece of plain paper, said, “Where there’s a will, there’s a way.”

Why did Einstein write the notes? Some believe they were to express Einstein’s delight at the reception he received from the people of Japan who crowded to attend the laureate’s (获奖者)lectures. Others think they were specially written for a bellboy who came to deliver a message, either because the scientist did not have loose change to tip him, or because the messenger refused to accept tips. Regardless of the reason, Einstein purportedly told the bellboy, “Maybe if you are lucky, those notes will become much more valuable than just a regular tip.” He was right!

Earlier this year, the bellboy’s nephew decided to part with the letters and handed them to Winner’s Auctions and Exhibitions. The “theory of happiness” brought the owner an astonishing $1.56 million from a European buyer. The second note, which opened at $1,000, and expected to fetch a maximum of $6,000, sold for $240,000!

1.What made Einstein become people’s focus again?

A.The theory of relativity. B.His new concepts of space.

C.The notes written by himself. D.His notes about his theory.

2.Where did Einstein write the words?

A.Bern. B.Stockholm.

C.Germany. D.Japan.

3.How were Einstein’s lectures?

A.They had a great effect. B.They attracted a lot of people.

C.They successfully inspired people. D.They were hard to understand.

4.How might the owner of the notes feel about the deal?

A.Disappointed. B.Curious.

C.Unfair. D.Unexpected.
