According to a recent article in The Wall Street Journal, we might all be braggarts(大话王) in this competitive society addicted to social networking.
Take a close look at your socialnetworking sites. Do you like to post photos of yourself in restaurants to show others what an exciting life you have? Or do you like to write about how happily in love you are? Or perhaps you are of the subtle type who constantly complain about jobs but really just want to impress others with your important position.
According to the results of a series of experiments conducted by Harvard University neuroscientists(神经科学家), the reward areas of our brain——the same areas that respond to “primary rewards” such as food ——are activated when we talk about ourselves. We devote between 30 to 40 percent of our conversation time to doing just that. Unfortunately, Bernstein says, some people can't tell the difference between sharing positive information that others might actually want to know and direct bragging. She suggests that bragging involves comparison, whether stated or implied.
“We are expected to be perfect all the time. The result is that more and more people are carefully managing their online images”. says Elizabeth Bernstein, a columnist with the Wall Street Journal.
But the issue is not limited to the Internet. In a fiercely competitive job market we must sell ourselves on multiple platforms and show that we are better than others. In fact, we have become so accustomed to bragging that we don't even realize we are doing it, says Bernstein. This is harmful to our relationships and puts people off.
Bernstein talked to some experts who said that people brag for all sorts of reasons: to appear worthy of attention; to prove to ourselves we are doing fine and that people who said we would fail are wrong; or simply because we're excited when good things happen to us.
“Feel sorry for them, because they're doing this unconscious, destructive thing that won't help them in the long run，” said Professor Simian Valier, a research psychologist at Washington University. The underlined word “subtle” in Para.2 is closest in meaning to “________”．
| A．hidden | B．apparent |
| C．outstanding | D．simple |
Which of the following is one of the features of braggarts?
| A．They control conversation and only talk about themselves. |
| B．They know well how to share positive information. |
| C．They selfpromote to stand out in their career. |
| D．They don't pay much attention to their online image. |
What can we infer from the passage?
| A．Braggarts make a good first impression but the effect decreases over time. |
| B．People who like bragging know what they are doing. |
| C．Braggarts always adopt comparison directly to show they are excellent. |
| D．They care much about the feelings of others when talking. |
I suddenly heard an elephant crying as though frightened. Looking down，I immediately recognized that something was wrong，and ran down to the edge of the near bank. There I saw Ma Sha with her three¬ month¬ old calf struggling in the fast rising water，and it was a life and death struggle. Her calf was floating and screaming with fear. Ma Sha was as near to the far bank as she could get，holding her whole body against the rushing water，and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean （完全地）over the mother's body and was gone. Ma Sha turned quickly to reach it and pressed the calf with her head and trunk (象鼻) against the rocky bank. Then with a huge effort，she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment，she fell back into the river. If she were carried down，it would be certain death. I knew，as well as she did，that there was one spot (地点) where she could get up the bank，but it was on the other side from where she had put her calf.
While I was wondering what I could do next，I heard the sound of a mother's love. Ma Sha had crossed the river and got up the bank and was making her way back as fast as she could，roaring (吼叫) all the time，but to her calf it was music.The moment the author got down to the river bank he saw __________.
| A．the calf was about to fall into the river |
| B．Ma Sha was placing the calf on the rock |
| C．the calf was washed away by the rising water |
| D．Ma Sha was holding the calf against the rushing water |
How did the calf feel about the mother elephant's roaring？
| A．It was a great comfort. | B．It was a sign of danger. |
| C．It was a call for help. | D．It was a musical note. |
What can be the best title for the text？

It’s never a real problem for us when the weather gets cold. We can put on more clothes, stay next to a fireplace, turn on the air conditioner or simply travel to a warmer city to spend the winter – people have many different ways of dealing with the cold.
But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat ( 发热) to keep themselves warm. So how do they manage to survive the freezing winter?
It turns out that plants have their own strategies （策略） too, said a study published on Dec 22 in the journal Nature.
According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues （活组织） can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite ( 相当于冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing (解冻) can cause air bubbles （气泡） to form in the plant’s water transport system. “If enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant,” she explained.
To live through cold weather, plants have developed three traits （特性） , according to the study. Some plants, such as oak trees（橡树）, avoid freezing damage by dropping their leaves before the winter chill sets in – effectively shutting off the flow of water between roots and leaves – and growing new leaves and water transport cells when the warm spring returns.
Other plants, pine trees（松树） for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.
The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
However, the study also found that these smart strategies were developed very slowly – over millions
of years of evolution （ 进化）. This leads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.
Scientists are hoping that this study can help people find possible ways to save plants from the threat
of climate change.What is the article mainly about?
| A．Why plants are not afraid of the winter chill. |
| B．The ways that plants survive cold weather. |
| C．Changes in plants’ water transport system in winter. |
| D．How plants evolve to keep up with climate change. |
According to the article, if a plant freezes in the winter, ______.
| A．it produces more living tissues to stay alive |
| B．its leaves quickly fall out and its roots begin to die |
| C．lots of air bubbles form in its water transport system |
| D．its water transport system could be blocked in the spring |
What are scientists worried about when it comes to plants according to the article?
| A．Plants may not be able to adapt to the increasingly cold climate. |
| B．Human activities might have a great impact on the pace of plants’ evolution. |
| C．Plants may not be able to evolve fast enough to adapt to human-caused climate change. |
| D．The strategies plants develop are not good enough to protect them against cold. |
The old man walked with a cane (拐杖) slowly into the restaurant. His poor jacket, patched (打补丁的) trousers, and worn-out shoes made him stand out from the usual Saturday morning breakfast crowd.
He walked toward a table by the window. A young waitress watched him and ran over to him, saying, “Here, Sir. Let me give you a hand with that chair.”
Without a word, he smiled and nodded a thank you. She pulled the chair away from the table. Supporting him with one arm, she helped him move in front of the chair, and get comfortably seated. Then she pushed the table up close to him, and leaned his cane against the table where he could reach it.
In a soft, clear voice he said, “Thank you, Miss.”
“You’re welcome, Sir.” She replied. “My name is Mary. I’ll be back in a moment. If you need anything, just wave at me.”
After he had finished a hearty meal of pancakes, bacon, and hot lemon tea, Mary brought him the change, helping him up from his chair and out from behind the table. She handed him his cane, and walked with him to the front door. Holding the door open for him, she said, “Come back and see us, Sir!”
He nodded a thank you and said softly with a smile, “You are very kind!”
When Mary went to clean his table, she was shocked. Under his plate she found a business card and a note written on the napkin, under which was a $ 100 bill.

We are naturally drawn to friends and colleagues with familiar voices, scientists have found．People prefer those who have a similar accent，intonation and tone of voice to themselves , they discovered．
Previous research has focused on how masculine or feminine a voice sounds．Men with deeper voices and women with slightly higher voices were thought to sound more attractive，because they suggest a bigger or a smaller body．
But the new study，published by a linguistics(语言学)expert in Canada，suggests there is a
more complex mechanism(机制)at play．Dr Molly Babel, from the University of British Columbia in Canada, said，“The voice is an amazingly flexible(灵活的)tool that we use to construct our identity．Very few things in our voices are changeless，so we felt that our preferences had to be about more than a person’s shape and size．’’
She recorded 30 volunteers’ voices and asked each to rate the others’ attractiveness on a scale of one to nine．Each participant was from western America，with similar accents．The people we assessed were all in the same dialect group，but they showed that dialect to different degrees．
“We seem to like people who sound like we sound，we like people who fit within what we know，”Dr Babel said．She also found that breathy voices in women－typified by the famous American actress Marilyn Monroe－were seen as more attractive．
The breathy tone，caused by younger and thinner vocal cords(声带)，implied youthfulness
and health A creaky voice，suggesting a person has a cold，is tired or smokes，was seen as unattractive．The participants preferred men who spoke with a shorter average word length and deeper voices．
The linguist，whose work is published in the journal PLOS One，said，“Once you’re outside of a certain range of familiarity，novel and exotic sounding voices might become more attractive．We also have to keep in mind we find some accents more preferable than others because of social fixed ideas．”In terms of voice preferences，the new findings highlight_______.
| A．body size and shape | B．shorter word length |
| C．thicker vocal cords | D．the same social groups |
Dr. Molly Babel mentions Marilyn Monroe in order to________.
| A．evaluate a creaky voice |
| B．explain her new findings |
| C．challenge previous research |
| D．promote the actress’s reputation |
According to the passage，who would most probably have a creaky voice?
| A．An old lady with a silvery voice． |
| B．A young lady with a thin voice． |
| C．A deep-voiced man with a dry throat． |
| D．A little man with a quiet and gentle voice． |
What can be inferred from the last paragraph?
| A．People favor familiar accents when in a new place． |
| B．People might have a preference for different accents． |
| C．Voice preferences have no link to long-held belief． |
| D．Voice preferences are influenced by sex differences． |
The main purpose of the passage is to________.
| A．encourage men to use shorter words and talk less |
| B．inform readers of the findings of voices |
| C．argue against women’s breathy way of speaking |
| D．compare male voices with female voices |
BERLIN (Reuters)—Germany’s postal service has announced plans to explore improved service and help protect the environment by getting “fetch friends”—ordinary people traveling across cities—to deliver parcels on their way.
It is hoped that the move, which will be tested in the coming months, might lessen traffic in inner cities and reduce CO2 emissions(排放). This should help DHL, a division of the German postal service, reach its target of improving the company’s carbon efficiency by 30 percent before 2020.
“As the world’s biggest logistics(物流) provider, we recognize a special responsibility to reduce the impact on the environment as much as possible,” said Frank Appel, Chief Executive Officer of Deutsche Post DHL, in a statement referring to a variety of measures being considered.
The “fetch friends” find out online about parcels that need delivering to people who live or work along the way that they are planning to travel through the city. They then select the ones that they want to take.
Codes(编码) sent to their mobile phones tell the volunteers where to pick the packages up. Parcels can be taken part of the way or passed on to another volunteer but all volunteers need to have the right code on their mobile phone so the track and trace system can be updated.
Logistics companies will be responsible for looking after the operation to make sure that the privacy of post is respected.
It’s hoped that this could be done using mobile phones but DHL says it recognizes that some security issues remain to be worked out.According to the passage, the “fetch friend” program ________.
| A．has been tested for months |
| B．aims to reduce the cost of the service |
| C．employs environmentalists to help with deliveries |
| D．encourages ordinary people to help cut the carbon footprint |
Which of the following statements is TRUE of DHL?
| A．It belongs to the Germany’s postal service. |
| B．It has the most up-to-date tracking system in Germany. |
| C．It has succeeded in improving its carbon efficiency by 30%. |
| D．It has designed many measures to improve its service speed. |
What may be a problem with the new service according to the article?
| A．Volunteers’ not allowing to select parcels. |
| B．The wrong codes in the mobile phones. |
| C．The possibility that parcels could be opened on the way. |
| D．Parcels’ being taken to the destination by a single volunteer. |
What might be the best Title for the best passage?
| A．New Challenges for the Postal Service |
| B．A Greener Way to Deliver Parcels |
| C．Solutions for Global Warming |
