Ever wonder why sometimes a hug is all you need ? You can’t explain it , but there’s just something comforting about being in your wife’s arms after a rough day or giving mom a hug after a long time apart .
A new study says the warm feeling in a hug is more than just skin deep . Researchers from the University of California , Berkeley believe that this loving feeling could have anti-aging benefits .
Oxytocin , sometimes referred to as the “ love hormone（荷尔蒙）” or the “ trust hormone , ” is responsible for those indescribable feelings we get when we’re bonding with a lover or a loved one .
Levels of the hormone drop as we age , and evidence suggests that could be a contributing factor to the deterioration of our bodies as we age . Muscle loss in particular is one of the major side effects of aging , with our bodies losing up to 5 percent of our muscle mass each decade past our 30s .
In the study , published in the journal Nature Communications , researchers injected oxytocin into older mice with muscle damage . The older mice had lower levels of the homeone than younger mice initially . But after nine days , the older mice who were given the hormone healed better than those who did not . In fact , their ability to repair muscle damage was up to 80 percent that of the younger mice .
The results were not only fast-acting , but provide hope for future uses of the hormone in a variety of anti-aging capacities . “ This is good because it demonstrates that extra oxytocin improves aged tissue stem cells（组织干细胞）without making muscle stem cells divide uncontrollably , ” study co-author Wendy Cousins said in a statement .
Previous uses of anti-aging molecules have also been associated with higher cancer risk , but researchers are hopeful that oxytocin can be useful in humans without this risk . In the future , researchers of Berkeley say oxytocin could be used to fight other age-related health issues by improving bone health and even being used as an alternative to hormone replacement therapy .
Now go out and give someone a hug .According to the passage , oxytocin __________ .
| A．decreases when people get older |
| B．creates loving feeling on the skin |
| C．leads to the great loss of muscles |
| D．can be used in humans without any risk |
The underlined word “ deterioration ” in Paragraph 4 probably refers to the state of __________ .
| A．getting fatter | B．becoming worse or less |
| C．growing stronger | D．dividing uncontrollably |
What can be learned from the research ?
| A．All the older mice healed faster in the research . |
| B．Older mice healed better than younger ones after 9 days . |
| C．Extra oxytocin in older mice controlled muscle cell division . |
| D．Mice with oxytocin injection improved the ability to repair muscle damage . |
What can be a suitable title for the passage ?
| A．When Do We Need A Hug ? |
| B．A New Anti-aging Product |

To Chinese immigrants, in the mid-1800s, California was “The Land of the Golden Mountain.” In their homeland they had heard the words, “There’s gold in California.” They sailed 7,000miles to join the gold rush and strike it rich. Between 1849 and 1882, more than 30,000 Chinese came to California. Most were men. They had been farmers in China. They came here to be miners and laborers. They ended up doing many other jobs, too.
Like many other immigrants, they did not plan to stay in America. They came because of their ties to their homeland and their families. They planned to return to China with their fortunes and help their families.
Only a few Chinese gold miners struck it rich. Most picked over the areas that had been mined already. But still, white miners resented the Chinese. Slowly, they drove the “yellow peril” from the mining camps.
By the end of the 1850s, many Chinese returned home. Those who stayed found other jobs.
Few women had come west in the gold rush. The Chinese saw a good business opportunity. They began doing the jobs women would have done. Many became house servants. Many more opened laundries.
The Chinese opened restaurants. Chop suey and show mein are popular Chinese-American dishes. The Chinese probably created these dishes to serve to the white miners. Other Chinese became fishermen, farmers, and even cigar makers. Why did Chinese go to America in the mid-1800s?
| A．Because they could find good jobs there. |
| B．Because they had found gold there. |
| C．Because they could open laundries and restaurants there. |
| D．Because they heard there was gold there. |
The underlined word “resented”(L.2,Para.3 ) mean “________”.
| A．liked | B．helped | C．hated | D．served |
Which should be the title of the passage?
| A．Early Chinese immigrants in America |
| B．Dream to strike it rich |
| C．The difference between men and women |
| D．Gold miners in America |
In her new book, “The Smartest Kids in the World,” Amanda Ripley, an investigative journalist, tells the story of Tom, a high-school student from Gettysburg, Pennsylvania, who decides to spend his senior year in Wroclaw, Poland. Poland is a surprising educational success story: in the past decade, the country raised students’ test scores from significantly below average to well above it. Polish kids have now outscored American kids in math and science, even though Poland spends, on average, less than half as much per student as the United States does. One of the most striking differences between the high school Tom attended in Gettysburg and the one he ends up at in Wroclaw is that the latter has no football team, or, for that matter, teams of any kind.
That American high schools lavish more time and money on sports than on math is an old complaint. This is not a matter of how any given student who plays sports does in school, but of the culture and its priorities. This December, when the latest Program for International Student Assessment(PISA) results are announced, it’s safe to predict that American high-school students will once again display their limited skills in math and reading, outscored not just by students in Poland but also by students in places like South Korea, Belgium, the Netherlands, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.
Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader—a mother with three children in the school—was asked about the school’s flaws. When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”
One of the ironies of the situation is that sports reveal what is possible. American kids’ performance on the field shows just how well they can do when expectations are high. It’s too bad that their test scores show the same thing.Tom decides to spend his senior year in Poland because _______.
| A．he intends to improve his scores |
| B．Polish kids are better at learning |
| C．sports are not supported at schools in Gettysburg |
| D．there are striking differences between the 2 countries |
According to Paragraph 2, we know that _______.
| A．PISA plays a very important role in America |
| B．little time is spent on sports in Japanese schools |
| C．American high schools complain about sports time |
| D．too much importance is placed on sports in America |
The underlined sentence in the last paragraph means _______.
| A．low expectations result in American students’ poor PISA performance |
| B．high expectations push up American students’ academic performance |
| C．American students’ academic performance worries their parents a lot |
| D．lacking practice contributes to American students’ average performance |
The purpose of this article is to _______.
| A．compare Polish schools with those in America |
| B．call on American schools to learn from the Polish model |
| C．draw public attention to a weakness in American school tradition |
| D．explain what is wrong with American schools and provide solutions |
For decades, families settled on the sofa to share the latest news and TV series, until additional bedroom TV, computer games and the Internet almost put an end to family rows over who held the remote control. Now, however, the traditional living room scene is making a comeback. A study by the communications watchdog Ofcom has found families are once again gathering around the main television set, but they are bringing their pads and smartphones with them.
“The 1950s living room is making a comeback as a family entertainment centre,” said Jane Rumble, head of media research at Ofcom. “We are watching on much better, bigger, and more delicate television sets, but we are coming into the living room holding our connected devices.” While the family are coming together once more, comparisons with the past end there. With a range of smaller screens on hand, not everyone sitting on the sofa shares the same viewing experience.
The coronation (加冕礼) may have drawn the undivided attention of 20 million viewers in 1953, but those watching the Queen’s Jubilee celebrations 50 years later were as likely to be commenting online about BBC’s broadcast as watching it. “Just a few years ago, we would be talking about last night’s TV at work or at school,” said a viewer, “Now, we’re having those conversations live while watching TV, using social media, text and instant messaging.”
It is a behaviour of media meshing（联网）, whose influence was underlined during this year’s Wimbledon men’s tennis final. As Andy Murray pushed towards his victory, 1.1 million people worldwide sent an average of over two microblogs about the match.
People use the Internet to enhance their television experience, for example, by reading a newspaper live blog about a football match while watching the action on the main screen. For a huge number of younger viewers, the portable screen offers a chance to do something unrelated, such as online shopping, listening to music or watching another television programme.
Some 70% of 16-to-24-year-olds claim to be absorbed in what Ofcom calls “media stacking” at least once a week. For TV viewers, the Internet scanning is the most popular activity, but they are also calling friends on the phone or sending emails and texts. Surprisingly, 12% claim to have listened to the radio with the television on, and 6% say they have watched another video in the meanwhile. According to the study by Ofcom, family members nowadays _______.
| A．care more about who holds the remote control |
| B．share the same programmes in the living room |
| C．watch better and more delicate television programmes |
| D．enjoy TV together with various smaller screens on hand |
This year’s Wimbledon men’s tennis final is mentioned to indicate _______.

Which shows the phenomenon of “media stacking” in the last paragraph?
| A．People are watching TV while shopping online. |
| B．People are watching a broadcast of a coronation. |
| C．The Internet makes people spend less time on TV. |
| D．The Internet enriches people’s television experience. |

Expensive and new gloves allow chatterboxes（话匣子）to take the term “handsfree” to a new level—by talking into them as they make a call. The gloves are known as “Talk to the Hand” and cost £1,000 a pair. They fixed a speaker unit into the thumb and a microphone into the little finger that can be connected to any mobile handset using Bluetooth.
Artist Sean Miles designed the new gloves that double as a phone in part of his project that shows the possibilities of gadget recycling. He uses outdated gloves and combines them with parts from mobile handsets recycled through O2, which commissioned（承担）the project. Mobile phone users will be able to keep their hands warm while they chat without taking their phones out of their pockets or handbags.
Mr Miles designed two pairs of the new gloves—one in pink and the other in brown and yellow. They will appear in an exhibition this July and visitors will be able to win the gloves. If demand is high, they will then be produced on a larger scale. O2 Recycle, which backed the project, estimates that there are already 70 million unused mobile handsets in the UK. The service pays up to £260 to those who recycle gadgets including phones, handheld consoles, MP3 players and digital cameras.
Designer Sean Miles hopes his work will get people thinking about recycling. The 41-year-old said, “I hope that my ‘Talk to the Hand’ project will get people to think again about the waste created by not recycling gadgets. If a few more people recycle their gadgets rather than send them to trash, I think this project will have fulfilled its aim.”
Bill Eyres, head of O2 Recycle, urges people to recycle their phone responsibly. He said, “There’s a pressing need for all of us to look at outdated handsets, and all the gadgets that we move on from or upgrade each year. Whether they are consoles or cameras, we should think of them as a resource that we need to recycle responsibly rather than throw them away.”The underlined word “O2” in Paragraph 2 is probably the name of ______.
| A．an artist | B．a company | C．a mobile | D．an exhibition |
Consumers can buy the “Talk to the Hand” gloves ______.
| A．in the exhibition |
| B．from Mr Miles |
| C．when they are mass produced |
| D．after they recycle the gadgets |
The purpose of the project is to _______.
| A．promote the technology of IT |
| B．enable people to talk to their hands |
| C．raise people’s awareness of recycling |
| D．attract visitors’ attention in the exhibition |
What is the passage mainly about?
| A．New mobiles that are fashionable. |
| B．Outdated handsets that are upgraded. |
| C．Outdated gadgets that can be used for recycling. |
| D．New gloves that can be used for making phone calls. |
When the swim season began, my 11-year-old daughter, Elizabeth, and I cut a deal. She would go to practice three times a week and try really hard, and I wouldn’t make her compete in the swim meets because on the day of a meet, she would be nervous all day. Her nerves rooted from the possibility that she would do something horribly wrong and let everyone down.
Recently, they had a T-shirt relay, which works like this: one person from each relay team puts on a T-shirt and a pair of socks, swims 50 meters, and gets out of the pool. She takes off the clothes and puts them on the next person, who then swims 50 meters. This continues until everyone on the team has completed a lap.
By the last leg, Elizabeth’s team had built up a moderate lead. Then it was Elizabeth’s turn to swim. She seemed to swim faster in the T-shirt and socks than when she wasn’t wearing them.
Approaching the halfway mark, she was still in the lead. Then one of Elizabeth’s socks fell off and was floating in the pool. “She has to get that sock on before the end of the race,” a swimming official told her team, “or you will be disqualified.”
Everybody on her team started screaming, “Elizabeth! Elizabeth! Stop! Get the sock!” But she couldn’t hear them. As she started her last 25 meters, a girl in Lane 2 was gaining on Elizabeth. It was time for desperate measures. A girl on my daughter’s team jumped in the pool, grabbed the sock, and swam after Elizabeth. She grabbed Elizabeth’s foot. “You have to put the sock on,” the girl screamed. Elizabeth continued swimming while her teammate put on the sock.
By now, the girl in Lane 2 was about to pass Elizabeth. With the sock finally on, Elizabeth swam her heart out for the last 15 meters. It was close, but Elizabeth beat the other girl to the wall for the victory.
On the ride home, she relived her moment of glory again and again. She told me that if the T-shirt relay was an Olympic event, her team would win the gold medal. I told her that in my professional opinion, she was absolutely right. Elizabeth was nervous about swim meets because she _______.
| A．was afraid of disappointing everyone |
| B．didn’t expect to lose the swim match |
| C．didn’t want to compete against other girls |
| D．was worried about making errors in public |
From the passage, we know that _______.
| A．socks contributed greatly to Elizabeth’s victory |
| B．the match nearly drove Elizabeth desperate |
| C．good luck finally fell on Elizabeth’s team |
| D．Elizabeth’s team narrowly won the match |
It can be inferred that Elizabeth would _______.
| A．swim faster in the T-shirt |
| B．enjoy swim meets later on |
| C．experience the moment again |
| D．take part in an Olympic event |
