Here’s a new reason to be an optimist. 1. Pessimists, of course, might have suspected this all along-but now there’s actual research behind it.

Boston-area scientists found the most optimistic people live an average of 11 to 15 percent longer than their more pessimistic peers.

In previous studies, researchers have found that more optimistic people tend to have lower risk of diseases and early death, said Lewina Lee, the lead researcher and a psychiatry professor at Boston University School of Medicine. “2.“

Optimists generally expect good things to happen in the future and feel like they can control important outcomes. They tend to stay positive whatever comes their way.

3. There’s good news: The mind-set is about 25 percent hereditary (遗传的). Lee said, meaning people have some control over their level of good thoughts. She said people can become more optimistic by imagining a future in which their goals have been reached.

To conduct their research. Lee and the other scientists compared results from two independently conducted studies-one that followed nearly 70,000 women for a decade and another that followed about 1,400 men for 30 years. 4. They ranked themselves on statements including in uncertain times, “I usually expect the best” or “I'm always optimistic about my future.”

The conclusion that optimistic people tend to live longer holds true regardless of other factors, Lee said.

The study leaves one question unanswered: 5. Although it's unclear, the researchers believe optimists may be better at regulating stressors and bouncing (反弹) back I from upsetting events. Optimists also generally have healthier habits, like exercising more and smoking less.

A.Not a natural optimist?

B.Our study took it one step further.

C.Why are optimists likely to live longer?

D.Why do women generally live longer than men?

E.An optimist sees the opportunity in every difficulty.

F.People self-reported their optimism on questionnaires.

G.Those who see the glass as half full, according to a new study, live longer.

An obvious reason for learning a new language is to be able to communicate with the people who speak it.1. People in every country prefer it when tourists make an effort to speak the local language, even if all you can say in it is “hello” and “please”.

Cultural understanding

Speaking a new language helps you to get to know another people and culture, as language and culture go hand in hand.2. It shows new ways of looking at the world. In addition, when you speak another language, you can enjoy literature, film, and music in the original language. It is extremely difficult for a translation to be a perfect replica (复制品) of the original. 3..

Business and careers

4. Schools and employers tend to prefer candidates who speak one or more foreign languages. Even though English is widely spoken in much of the world, the fact is that the global economy depends on communication. When dealing with France, for example, someone who speaks French will have an obvious advantage over someone who doesn’t.

Language improvement

Learning another language can help you to understand your own. Many languages have contributed to the development of English.5. Also, in learning how another language differs from your own, you will increase your understanding of your own language. For many people, language is innate (与生俱来的) — we know how to say something, but we don’t necessarily know why we say it that way. Learning another language can change that.

A.Language is helpful in making foreign friends.

B.The best way is to read what the author actually wrote.

C.Learning another language opens one’s mind to new ideas.

D.Your trip will be comfortable if you speak the local language.

E.Speaking more than one language will increase your market ability.

F.It is true that mastering another foreign language is very beneficial.

G.Learning those will teach you where words and even grammatical structures are from.

Some pigs lend to be optimistic while others have a more pessimistic view, according to a new research that is meaningful to animal welfare. The study, published in the journal Biology Letters, is the first to show that mood and personality interact in an animal, influencing judgment.

Asher, a researcher at the University of Newcastle's Institute of Neurowcience, and her team housed groups of pigs in the two types of environments. One reflected sandard commercial conditions and the other was cushier with more space and plenty of sell, deep straw. After the pigs got accustomed to these new homes over a few weeks, the rescarchers picked 18 pigs from each type of housing arrangement to train and test their judgment.

"To do this, we trained each pig that in one corner of a training room there would be a bowl with chocolate sweets — specifically M&Ms, pigs love M&Ms — and in a bowl at the opposite side of the room there would be a bowl that would contain coffee beans, which pigs find bitter-tasting," senior author Lisa Collins of the University of Lincoln's School of Life Sciences said.

Over a number of training trials, pigs learned to go to the bowl reliably when it was in the corner where they had figured out to expect M&Ms. On the contrary, they quickly learned to avoid the bowl when it wasn't in the corner where they would expect to find the coffee beans.

The rescearchers next placed an unfamimliar bowl in different locations, to see how the pigs would react. Some gaily dashed to the bowl no matter what, exhibiting optimism that it would contain their favorite foods. Others, however, behaved as though they expected it to contain coffee beans, displaying pessimism.

The findings suggest that a one-size-fits-all answer to animal welfare issues does not exist. Even if pigs are just equal to bacon or other meal for some people, there is still cause for concern. Students have suggested that how an animal is treated during its lifetime can directly affect meal quality and taste.

1.What was the study devoted to figuring out?

A. The influence of pigs' living environment.

B. The influence between humans and pigs.

C. The didferences of two types of pigs' personality.

D. The relationship between pigs' mood and judgment.

2.What does the underlined word “cushier” in Paragraph 2 mean?

A. simple.　　　　　　 B. more comfortable.

C. non-profitable. D. less free.

3.Which bowl can test whether a pig is optimistic or pessimistic?

A. The bowl with chocolate sweets.

B. The bowl containing coffee beans.

C. The bowl full of both sweets and beans.

D. The bowl unfamiliar to two types of pigs.

4.What do the findings of the new research imply?

A. People should treat pigs equally.

B. People's health relies on meat quality.

C. People should meet pigs' various needs.

D. People's attitude toward pigs is totally wrong.

The results of an admittedly small but telling new study suggest that Medicare and other insures could be spending billions of dollars on screening(拍片检查)smokers for lung cancer that would be better spent on helping them quit and keeping others from starting．The new study indicated that screening more often supported smokers’ beliefs that they could safely continue to smoke．Most participants remained smoker because they believed screening could catch cancer early before it would threaten their lives.

“They compared how hard it was to quit smoking with how easy it was to be screened，”said Steven B. Zeliadt, the lead author of the study. "They engaged in magical thinking that now there's this wonderful painless external test that can save lives."

He and seven colleagues conducted the study of 37 current smokers who were offered lung cancer screening at Department of Veteran Affairs. After being screened and told the results. they were interviewed about their smoking-related health beliefs. For about half of those in whom cancer was not found. "Screening lowered their motivation for quitting." the team reported in July in JAMA Internal Medicine. The participants focused only on lung cancer, ignoring other potential harm of smoking. the researchers wrote.

A national study published four years ago found that annual CT screening for lung cancer three years in a row could reduce deaths among heavy smokers by about 20 percent.In an interview, Dr. Russell P. Harris, a preventive medicine specialist at the UNC-Chapel Hill. noted that "screening is being believed by people as an alternative to stopping smoking. But stopping smoking would have huge benefits for the individual and society." Furthermore, smoking causes many other cancers.

Dr. Harris agreed that rather than screening money is better spent on smoking prevention. He suggested providing free stop-smoking aids. sponsoring anti-smoking advertising and raising taxes on tobacco products and the age at which people are allowed to buy them.

1.What does the new study suggest?

A. Screening technology remains to be advanced and more effective.

B. Screening can find cancer in patients and give them timely treatment.

C. Helping people quit smoking is better than screening them for cancer.

D. Admitting smoking before screening can help one to stop smoking.

B. Steven Zeliadt and his colleagues.

C. Dr. Harris and his patients.

D. The patients' smoking-related health beliefs

It's impossible to provide an exact number of words in English, since new words are being added to the dictionary, and falling out of use constantly. 1.

The short answer is: about a million. Doubt you know anything even close to a million words? That number includes any number of legal, medical, scientific, and mechanical terms that most people will never meet in their day-to-day lives. 2.

The “million" number also includes the many, many words that have fallen out of use throughout the time.3. Consider the word “diddle"，a slang term from the 1700s that means “gin". Many English speakers would recognize “gin"，but far fewer would recognize “ diddle”.

If a million words is the absolute upper level, how does that compare with the general vocabulary of most English speakers? 4. Most English-speaking adults know between 20,000 and 30,000 words. And in addition to those many thousands of words, they're probably able to comprehend a good 20,000 more just from context clues.

5. You won't find a single dictionary that includes anywhere close to the total million words. One of the reasons is that general-usage dictionaries don't include lots of technical terms—both because of how uncommon they are and, in some cases, because of length. The longest word in the English language is a term from chemistry that is used to identify a certain kind of protein. It is 180,000 letters long. So you certainly won't see it in the dictionary.

A.But what's the number?

B.More than you might think!

C.That doesn't amount to a whole lot, though!

D.Then, how many words are there in the book?

E.While words like these are very uncommon, they still count.

F.If you recognize these uncommon words, we sadly no longer use them.

G.Though removed from the dictionary, they still count as English words.

As a senior, my future is always on my mind. To be exact, thoughts of the future have kept me up countless nights and made me worry enough to do poorly on more than one test. Because of this, words of wisdom are a source of comfort. Steve Jobs gave a speech to Stanford’s graduating class in 2005 and his words resound repeatedly in my mind whenever I think about my future.

It wasn’t always like that, though. It started when I became a junior, when college came into view. It’s the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He, too, felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well.

This doesn’t mean that students shouldn’t attend college, but rather that they shouldn’t worry so much. You’ll get where you need to go, even if your path is a bit more winding（蜿蜒的）than you’d like.

Jobs talked about the hardships in his work. His love of his work helped him carry on and he got where he was meant to be, which restates the point: don’t panic.

One particular part of his speech stayed with me. Steve Jobs quoted（引用）the saying “Stay hungry, stay foolish” and it has become my motto. Staying foolish is realizing that you are still a fool, no matter how much you’ve learned or experienced. There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated.

Steve Jobs’s level of success is attainable, and I aim to prove that. With the will power to go into the world living every day like it’s my last and allowing the future to take care of itself, I will do great things. In the last moments of my life, I’ll be proud of what I have done and hope to have all the wisdom a person could wish for.
