1 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?

2 . Kyle Cassidy and three other members of the Annenberg Running Group were stretching on the grounds of the University of Pennsylvania, waiting for a few latecomers. The Penn colleagues and other community members meet three days a week for a roughly 30-minute jog and an occasional lecture. That's right― during some runs, one of them delivers a talk. Topics range from the brain to Bitcoin.
But on this day last January, it would not be their normal run. The first clue that something was off was the man who sprinted past them. "Running at an amazing pace," Cassidy told Runner's World admiringly. Cassidy discovered why the sprinter was so fleet of foot when another man ran by, yelling, “Help! He took my phone and laptop!"
At that, the group did what running clubs do: They ran, trailing the suspect down the streets of Philadelphia until he ducked into a construction site. The runners split up. Cassidy ran around to the far side of the site to cut the thief off while the others wandered the neighborhood hoping he had dumped the loot （赃物）in a backyard.
No luck. So they decided to ask residents whether they'd seen the guy. When they knocked on the door of one row house, they were in for a surprise. Unknown to them, he had already emerged from the construction site—and was hiding behind a bush by that very house. As the owner opened the door, the suspect darted out from behind the bush ... and right into the arms of campus police, who'd joined the chase shortly behind the runners.
The members of this running group are not hard-core athletes. But they do understand the benefit of a little exercise. ''Running is typically a useless sport where you turn fat cells into heat," Cassidy told The Philadelphia Inquirer. "But occasionally it can be useful, and here was one of those opportunities."

3 . The New South Wales government used planes to drop more than 4,000 pounds of carrots and sweet potatoes, to the forests which are damaged by the recent wildfires. The fires are reported to have killed more than a billion wild animals and destroyed a land of more than 84 thousand square kilometers—about twice the size of Maryland. What is worse, most Australians are worrying about when the wildfires will be fully put out.
“The home of several important wallabies (沙袋鼠) was burnt in the recent fires,” New South Wales Environment Minister Matt Kean said on Sunday. Kean said the drops are what wallabies need. The plan is designed to help wallabies and allow them to recover.
Fire seasons often take place in the country, but this year the fires have been quite devastating. The country experienced one of its hottest and driest years, which made it harder to put out the fires. Besides wild animals, the fires have taken the lives of at least 25 people and destroyed more than 2,000 homes.
“I think there’s nothing to compare with the damage that’s going on over such a large area so quickly. It’s a big event in terms of geography and the number of wild animals,” Dickman, an animal protection expert, said in an interview with NPR last week.
“We know that the number of Australian wild animals has been going down over the last several decades, and it’s probably fairly well known that Australia’s got the world’s highest rate of extinction of animals,” he added. “It’s events like this that may increase the speed of extinction of a lot of other animals. So, it’s very sad time. Everyone has to try their best to do something for them.”

4 . World’s loneliest marathon
Many of us know about Russia’s Lake Baikal from our textbooks, or by listening to Chinese singer Li Jian’s hit song, Lake Baikal. But over the past decade, the world’s deepest freshwater lake has been in the spotlight for an extreme sport.
Each March since 2005, about 150 people from around the world sign up for the Baikal Ice Marathon. They come to explore the lake’s breathtaking beauty and challenge themselves in unpredictable conditions.
The 26-mile (41.84-kilometers) journey starts on the lake’s eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.
Known as the “blue eye of Siberia”, Lake Baikal has exceptionally clear waters. This means its ice is almost perfectly transparent. “Seen from above, a runner on the ice looks as if he or she is jogging through space,” The New York Times noted.
The landscape might be beautiful, but it’s also harsh. Strong winds blast across the lake and frostbite can occur within half an hour. Runners say the cold climate is what draws them. They want to test their limits.
“When you are in such an environment, you don’t have cars around you, you don’t have the noise around. I think these extreme races allow you to be alone with nature,” Alicja Barahona, a 64-year-old runner from the US, told ABC News.
The location offers some strange and unique characteristics for this marathon. The finish line is visible from the start, but the endless white offers no progress markers. The race also ends with little fanfare (喧闹). Tourists crowding the ice are mostly addicted to snapping selfies (自拍) and just ignore the runners.
For some runners, the absence of spectators (观众) makes the race more challenging, because it’s lonely. They must fight with themselves. “You are alone on Baikal. It is your race. You are alone with yourself. All you need to do is to defeat yourself,” Veronique Messina, a French runner, told the Telegraph.

5 . Looking for a place to take a rest，sip a cup of coffee and have a furry companion? Welcome to animal-themed cafes.
In recent years，the combination of pets and catering has become incredibly popular in many cities throughout China. While many cafes started out offering the company of cats and dogs，others are expanding their range. Some cafes include animals like squirrels，raccoons and even capybaras.
In reviews，internet users have commented that their main reason for visiting these businesses is to interact closely with animals they have only seen from afar.
“The customers love animals. They are curious about these pets and want to raise one at home，but circumstances don’t allow it，”said pet cafe owner Tian Rui，Liu Jing，a Beijing resident who works in finance，loves pigs，but her parents would not endorse her getting one as a pet. The 24-year-old had to admire the animals through videos and images. But now，she can have close contact with an adorable pig every weekend in a pet cafe.
Also，these pet cafes serve as a shelter for those who find comfort in being around animals. “In this place，you can get close to the cute little ones in a very comfortable way without having to worry about safety and hygiene(卫生)—overall，it is an extremely comfortable experience，”said Zhao Ming from Tianjin，30，a frequent pet cafe visitor.
Animal lovers also expect the pet cafes to change people’s attitudes toward pets. Animals like ducks，pigs and sheep have been served as food for many years. People hardly see them as pets. But the pet cafes help shift their attitude from seeing them as playthings to regarding them as family members or close friends.
“Whether at home or in stores，these little animals are there for companionship and they bring warmth to our hearts. They care and understand just like family members. They give us much more than the love we give to them，”Zhao said.

6 . Two of the saddest words in the English language are “if only”. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.
My father is famous in our family for saying, “Take the extra minute to do it right.” I always try to live by the “extra minute” rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only” moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.
I don’t only avoid those “if only” moments when it comes to safety. It’s equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you” or “I forgive you.” When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn’t be here. But then I thought about the fact that he’s 84 years old and I realized that I shouldn’t give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.
I know there will still be occasions when I have to say “if only” about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I’m doing the right thing. I’m buying myself peace of mind and that’s the best kind of insurance for my emotional well-being.
1. Which of the following is an example of the “extra minute” rule?| A．Start the car the moment everyone is seated. |
| B．Leave the room for a minute with the iron working. |
| C．Wait for an extra minute so that the steak tastes better. |
| D．Move an object out of the way before it trips someone. |
| A．keep her appointment with the eye doctor |
| B．meet her father who was already an old man |
| C．join in the holiday celebration of the company |
| D．finish her work before the deadline approached |
| A．abandoned | B．lacked |
| C．avoided | D．taken |
| A．To Keep Emotional Well-being | B．To Prevent “If Only” Moments |
| C．To Follow the Most Useful Rule | D．To Achieve the Peace of Mind |
7 . When it comes to the most famous 20th century painters of the United States, Grandma Moses should be mentioned, although she did not start painting until she was in her late seventies. As she once said to herself , “I would never sit back in a rocking chair, waiting for someone to help me”. No one could have had a more active old age．
She was born on a farm in New York State, one of five boys and five girls. At 12 she left home and was in domestic service until at 27 she married Thomas Moses, the hired hand of one of her employers. They farmed most of their lives, first in Virginia and then in New York State, at Eagle Bridge. She had ten children, of whom five survived; her husband died in 1927．
Grandma Moses painted a little as a child and made embroidery (刺绣) pictures as a hobby, but only changed to oils in old age because her hands became too stiff (僵硬的) to sew and she still wanted to keep busy and pass the time. Her pictures were first sold at the local drugstore and at a market and were soon noticed by a businessman who bought all that she painted. Three of the pictures were exhibited in the Museum of Modern Art, and in 1940 she had her first exhibition in New York. Between the 1930’s and her death, she produced some 2,000 pictures: careful and lively portrayals of the country life she had known for so long, with a wonderful sense of color and form. “I think really hard till I think of something really pretty, and then I paint it” she said．
1. What can we learn about Moses?| A．She stopped painting in her late seventies. |
| B．She still led an active life when she was old. |

8 . Have you ever noticed that the stars sometimes appear brighter in December, January and February? There's a link between cold air and the night lights. "Part of it is that it tends to be drier in the winter," said Diane Tumshek, an astronomer at Carnegie Mellon University in Pittsburgh, Pennsylvania. Even though it's invisible, moisture can change the way light moves through the air. And in the summer, moisture can make stars appear more dull.
Air temperature is also what puts the twinkle twinkle in the little stars. "Even on very clear nights, some of the atmosphere is cooler, and some of the atmosphere is warmer,” said Tumshek, who also works with the Allegheny Observatory. And when the light from a star passes through those bubbles of varying temperatures, "it bends and shifts the light, so that we are seeing stars appear to dance or twinkle,” she said.
For star lovers in the United States, there's another factor that comes into play for bright winter stars, although this is a matter of coincidence. During Earth's journey around the sun, “there are just simply more bright stars visible from the Northern Hemisphere in the winter sky," Tumshek said. If you really want to see a shiny star, just try to find a burning ball of gas called Sirius near the horizon. At 8.6 light-years away, Sirius is relatively close to Earth and the brightest star visible in the night sky. It is also large — nearly twice as big as our sun and 20 times as bright. So this winter, when the world turns cold and it seems like we should be spending more time indoors, consider asking an adult to go exploring outside. With a warm coat and a clear sky, any night can be turned into a treasure hunt. All you have to do is look up.
1. What does the underlined word "dull" in Paragraph 1 probably mean?| A．not shiny | B．not exciting | C．not severe | D．not smart |
| A．By changing the bubbles around them. | B．By putting the twinkle twinkle in them. |

| C．To present new research results about stars. | D．To explain why stars are more visible in winter. |
9 . Our culture is the system we use to build our identity. All living things are part of a culture. Even animals have a culture! So what is culture? It's the way we behave in a group. It begins with each individual (单个的) family. Within our families we do things to build relationships with each other. This can include routines like daily housework and weekly shopping. It also includes traditions. Traditions are activities that are repeated on a regular basis.
Culture is not limited to individual family groups. The real strength of culture is in larger community groups. These larger groups are called societies. Every society makes rules for itself. It decides how people should act in different situations. Some of these rules are written down. Some are just things that are naturally expected of all members of that society.
Often, cultures can be recognized by what the people believe. Cultures are also known by what they choose to include in their art. Sometimes cultures may be formed by people who speak the same language. Cultures may also be known for their customs, including the foods they make and the things they do.
Our cultures help us understand who we are and what we believe. There are very strong feelings connecting us to our own society. Two different cultures may disagree on something, especially if they both feel strongly about it. When that happens, war is a common result.
People are learning better ways to communicate with each other. The more we communicate, the more we appreciate the differences in cultures.

| C．By communicating. | D．By making friends. |
| A．What Is Culture? | B．What Is Society? |

10 . Many people feel that dream is unique to humans. However, many dog owners will likely disagree on that. They have noticed that their dogs at various times during the sleep may shake legs, snort (哼) and sometimes growl (低声吼叫) which gives the impression that they are dreaming. These things may wonder us about whether dogs dream.
Scientists confirm that dogs probably do dream. It turns out that dog brains and human brains have many similarities during sleep cycles. Researchers used special machines to measure electrical activity in a dog’s brain and human’s brain. Scientists already knew that when humans dream, a certain part of the brain is active during sleep. Researchers discovered that the same part of the brain is active in sleeping dogs. Scientists have other data that back up these findings.
Many people dream that they are trying to move but cannot. Interestingly, part of that experience is not a dream. When people sleep, the brain produces a chemical that causes the dreamer to become temporarily paralyzed (使麻痹). Researchers think this happens so that people cannot physically act out dreams while they are sleeping. Dog brains make the same chemical. In one study during which this chemical was blocked, sleeping test dogs performed physical activities, such as standing up, sniffing around the room for imaginary rabbits, or chasing imaginary balls.
Because of these similarities, researchers believe that the content of a dog’s dream might come from the same source as a human’s dream. “People’s dreams are usually based on things they did that day,” says Dr. Samantha Hudspith. “So there is reason to believe that dogs dream about the things they’ve done that day. Of course, there will never be a way to prove this. Dogs cannot describe their dreams the way that humans can.”
