1 . Surfing the Internet for fun will make you a better employee, according to an Australian study.

The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive (有效率的) than those who do not. Study author Brent Coker said “Surfing the Internet at times helps increase an employee’s attention.”

“People need to relax for a bit to get back their attention,” Coker said on the university’s website.” Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day’s work, and as a result, increase productivity (生产效率),” he said.

According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos.” Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online,” said Coker. “That’s not always a good idea.”

However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.

2 . Over the years, I never thought of my father as being very emotional. He never was, ________ not in front of me. My father never told me he loved me when I was a child, and never held it against him. I thought that all I really wanted was for my dad to take________in me.

On November 9^th, 1990, I received________that my National Guard unit would be sent to the front. I went on to my father and gave him the news. I could feel he was ________about my going. We never________it much more, and eight days later I was gone.

A few days after Thanksgiving I was able to call my wife. She told me that my father said his usual Thanksgiving prayer (祷告). But this time he________ one last sentence. As he lowered his voice and a tear ran ________his cheek, he said, “ Dear Lord, please________over and guide my son, Rick, with your hand in his time of need as he ________ his country, and bring him to home________.” At that point he burst into tears. I had never seen my father cry, and when I heard this, I couldn’t help but cry myself.

Eight months later, when I returned home from________, I hugged my wife and children in tears. When I came to my father, I gave him a huge hug. He whispered in my ear, “ I’m very proud of you, Son, and I love you.” I looked at that man, my dad,________ in the eyes as I held his head between my hands and I said, “I love you too, Dad,” and we hugged again. And then together, both of us cried.

Ever since that day, my ________ with my father has never been the same. We have had many ________ conversations. I have learned that he’s always being proud of me, and he’s not afraid to say “I love you” any more.________ am I. I’m just sorry it has taken more than 30 years and a war to find it out.

4 . Passenger pigeons (旅鸽) were the most common birds in all of North America in the 1800s. It was common to see large groups of passenger pigeons — groups that made a sound like a storm. But today, they are extinct because of human behavior. Now, some scientists want to bring passenger pigeons back to life by using new technology and scientific ideas. They call this process de­extinction.

De­extinction has not happened yet. It is still just an idea. The process of de­extinction is not easy. First, scientists must collect DNA from the bodies of extinct animals. Then they will put it in the eggs of similar animal species. When these animals become adults, they will have babies. And these baby animals will have the DNA of the extinct animals.

Scientists believe it is possible to bring back passenger pigeons and many other animals. However, not everyone thinks this is a good idea.

Stuart Primm is the world's leading expert on modern animal extinction. He believes that bringing extinct animals back to life is bad for the earth. On one hand, these animals no longer have a safe place to live. On the other hand, they could cause other animals to die.

Many other scientists do not agree with Stuart Primm. Stuart Brand, a writer and scientist, is one of them. He believes de­extinction is good for many reasons.

"The current generation (当代) of children will experience the return of some unusual animals in their lifetime. It may be part of what defines their generation and their attitude to the natural world. They will take their parents to zoos to see the growing populations of passenger pigeons, and maybe even dodo birds. This will provide a good deal of money for zoos busy with extinct species restoration (恢复). Humans killed off a lot of species over the last 10,000 years. So, it's right to bring some back to life," he said.

5 . England

England is the biggest of the four countries in the United Kingdom. Over 50 million people live in England, which is around 80% of the total UK population.

    1     It is spoken today by billions of people all over the world. Many students go to England from other countries to study the language and learn about the culture. Although everyone speaks English, there are many different accents around the country. French was the official language in England between 1066 and 1362.       2    

The English people love music.       3     Glastonbury is a five-day festival of music, dance, comedy, and theatre and around 175,000 people go there. Many people stay at the festivals for a few days and they camp in tents. People listen to all types of music, especially pop and rock. England has produced many international groups and singers.

The most popular sports in England are football, rugby and cricket. Most towns have a football, rugby and cricket ground where teams can play.       4           Womenˈs football is also popular. Cricket is a traditional sport played with a bat and a ball. People like to watch all these sports on TⅤ．

England is a multicultural country.       5       Indian, Chinese and Italian foods are popular. Traditional English food includes fish and chips, roast beef, sausages and mashed potatoes. Many English people drink several cups of tea every day, usually with milk. However, different types of coffee are also popular.

6 . A rescue center in Alaska has taken in an orphaned baby seal (海豹) that was still in the body when a hunter killed its mother on Easter Sunday.

The Alaska Sea Life Center says a hunter killed the baby’s mother in a village on Nelson Island in the Bering Sea. The hunter then realized there was a live baby inside the seal and successfully delivered (接生) it.

The hunter’s daughter found a hotline of the Seward Rescue Center and called to report the incident. Guided by center staff, a village teacher helped transport the baby to the local airport, and the animal was flown to Anchorage. The Alaska Sea Life Center members met the baby, now called Maxwell, at the Anchorage airport and drove him to Seward on Monday. Staff members say the baby has responded well to food and care, but his condition is still considered very serious.

“Maxwell was close to full-term, and everything looks fairly normal,” said Pam Tuomi, a center vet. “But babies that have never received antibodies (抗体) from their mothers’ milk are at higher risk of infection (感染), so we will keep Maxwell in a separate place and watch him closely for the next few weeks.”

The Sea Life Center is Alaska’s only permanent facility licensed to house stranded marine mammals and seabirds. The staff choose a theme each year for naming animals admitted there, and this year the names are related to caffeine.

“We hope to give Maxwell a second chance to live as a wild sea,” said Brett Long, the center’s director.

There may be a slight chill(寒冷) in the air, with temperatures staying around 15℃ in March, but Spain’s handsome capital is slowly starting to warm up. Even more attractive are the cultural events.

A new exhibition on the living and working spaces of Spain’s greatest artist, Picasso, has just opened in the studio at the Fundación Mapfre at Paseo de Recoletos 23. It runs until 11 May with rarely seen pieces borrowed from his family.

Later this summer, the 400th anniversary of the death of the Renaissance(文艺复兴) painter El Greco will be marked with an exciting exhibition at the Museo del Prado at Paseo del Prado from 24June to 5 October.

The widest range of flights is offered by EasyJet—from Bristol, Edinburgh, Gatwick, Liverpool and Luton. British Airways and its sister airline Iberia combine forces from Heathrow and London City. Ryanair flies from Manchester and Stansted; Air Europa flies from Gatwick.

Barajas airport is 13km north-east of the city centre and is served by frequent trains on Metro line 8, but the shortest underground journey is a bit complex with at least one change at Nuevos Ministerios station and takes about 30 minutes. The fare to any station in the city centre is ∈4.50. The airport express bus runs every 15 to 35 minutes around the clock; ∈5 one way. It takes 40 minutes to reach the city centre. A taxi takes half the time. A flat rate of ∈30 covers most of central Madrid.

8 . A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.

The Robot Activity Support System, or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.

“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected,” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.

Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.

RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.

“While we are still in an early stage of development, our initial results with RAS have been promising,” Minor said. “The next step in the research will be to test RAS’ performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.”

9 . What’s your opinion on spicy food? Some people cannot handle even the smallest amount of chili peppers in their dinner while others can’t get enough of them.

Scientists have long been puzzled by why some people love the chili while others loathe it. Plenty of research has been done on the subject, dating as far back as the 1970s. Previous results showed that a love of chilies is related to childhood experiences, and that cultural influences affect our taste too. But the latest study has found that a person’s love of spicy food may be linked to his or her personality (性格) more than anything else, CBC News reported.

“We have always assumed that liking drives intake — we eat what we like and we like what we eat. But no one has actually directly bothered to connect personality with intake of chili peppers,” said Professor John E. Hayes from Pennsylvania State University, who led the study.

But before you look at the study, you should first know that “spicy” is not a taste, unlike sour, sweet, bitter and salty taste. It is, in fact, a burning feeling that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people’s longing for thrill, something they usually get from watching action movies or riding a roller coaster.

In the study, 97 participants, both male and female, were asked to fill out questionnaires about their personality, for example, whether they like new experiences or tend to avoid risks. They were then given a glass of water with capsaicin (辣椒素), the plant chemical that makes a chili burn, mixed into it.

By comparing the answers to the questionnaire and what participants said they felt about the spicy water, researchers found that those who tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.

Interestingly, we used to believe that the reason why some people can withstand (耐受) spicy food is that their tongues have become less sensitive to it. However, this latest study has found otherwise. “It’s not that it doesn’t burn as badly, but that you actually learn to like the burning feeling,” Hayes explained.

Beijing Opera     1     （consider）as a national treasure in China, which     2     （date）back to 200 years ago. The early Qing Dynasty saw the great     3    （develop）of this opera. Qianlong emperor in the Qing Dynasty had     4     interest in the local opera.     5     （celebrate）his eightieth birthday, he asked opera troupes（戏班）    6     different places to perform for him in Beijing, so the four big Huiban Opera Troupes entered the capital.     7    （gradual）, they combined with the Kunqu Opera, Yiyang Opera, Hanju Opera and Luantan, and formed the present Beijing Opera.

Beijing Opera is a form of traditional Chinese theatre     8     combines music, performance, and dance. Many audiences from different     9     （country）think that it is the     10     （large）and most influential kind of opera in China and the influence is incomparable in China.
