Online “friends” – a threat to development
The impact of technology on the nature of our friendships has been a much - debated topic since the dramatic rise of social networks. Advances in mobile technology and social networking websites mean we spend more time online than ever before. It is therefore not surprising that so many psychologists, sociologists, and others are eager to give their thoughts on how this is impacting negatively on our society.
There is one element of social networking that is deeply worrying. We find ourselves in a hyper - connected world where people access social media day and night, excited to make announcements about the tiniest details of their lives. Research is starting to show that this culture is negatively affecting not our friendships but our character. Professor Larry D. Rosen says that young people who overuse social networking sites can become ineffective, and display anti -social behavior in their offline lives. But perhaps an even more disturbing effect is that one of our most basic emotions seems to be disappearing --empathy. This is the emotion that allows us to see the world from our friends’ points of view. Without it, we are far less able to connect and form meaningful adult relationships.
Professor Sherry Turkle suggests that people are no longer comfortable being alone. This is something confirmed by a study where 200 university students were asked to go without social media for 24 hours. Many admitted an addiction to their online social network; most complained that they felt cut off from family and friends. And yet being alone is a time when we self-reflect and get in touch with who we really are. It is only when we do this that we can make meaningful friendships with others.
These potential changes in our characters are rather alarming, so it is clear that we can’t neglect those negative impacts of social networks.
Sustainable Transport in Cities
Transporthas always shaped cities. In Medieval times crossroads gave birth to bloomingmarket towns. Many North American cities were created for the car. But how arethe cities of today being shaped by a need for more sustainable transport?
Manylocal governments are speeding up change through policy initiatives such asjoined transport, congestion charges and low emission zones, sustainablegaining and life-cycle costing, and opening data up to companies and academics.And these city level policies can move markets in more sustainable directions.
The least dense cities, for example, Houston, have per capita(人均价)carbonemissions nearly ten times higher than the densest, such as Singapore.
Light weighing and new engine and fuel technologies are helping to make existing road and rail vehicles more efficient.
A.Many options require city - level investment in new facilities. |
B.However, it is not yet clear which technologies and fuels cities will back. |
C.Through their actions, city governments today are helping to shape the cities of the future. |
D.For example, London is requiring all newly licensed taxis to be zero - emission capable from 2018. |
E.City planners are using transport - oriented development to increase density while maintaining quality of life and property value. |
F.Some cities, such as Delhi, are investing heavily in creating the mass transport systems needed to change how citizens travel. |
3 . ① Risk is something we face daily. However, some people are obviously more willing to take risks than others.
② Biologists appear to have discovered a physical reason that explains why some people are risk -takers. Dopamine is a neurotransmitter, a chemical that spreads signals between nerve cells. It is linked to the brains reward system and is the chemical that makes us feel good, and scientists believe it to be inked to risk - taking. Our nerve cells have dopamine receptors(接收器)which control the amountof dopamine that each cell receives. But not all receptors may be active. When a person had few active receptors to control the amount of dopamine that is received, a cell can become flooded resulting in an extreme feeling of happiness.
③ researchers at Vanderbilt University and Albert Einstein College of Medicine asked 34 men and women tocomplete a questionnaire about their risk taking to assess whether they seek new opportunities or are cautious in life. The results of the research were consistent with similar studies carried out with rats, and had the same outcome. It concluded that people who are risk-takers have fewer dopaminereceptors than people who are not. This suggests that the rush of pleasure a risk taker receives when a cell becomes flooded with dopamine can become addictive for some people. They therefore pursue new and exciting activities in order to try to repeat this feeling, and as a result their concern for risk becomes considerable reduced.
④ Dopamine gives us a biological reason for risk - taking, but scientists believe there may bepsychological reasons too. Sensation - seeking is a personality characteristic that describes the desire to find activities that bring us pleasure. In 1964,psychologist Marvin Zuckerman created the sensation - seeking scale. His 40-item questionnaire, still used today, was given to people who were active inseeking new activities, and to people who were more satisfied with a quiet life. While risk - taking is not a characteristic in itself, it is very much associated with sensation - seeking, as a high sensation - seeker does note valuate risk in the same way that a low sensation - seeker does. a desire toachieve pleasure means that there is a greater willingness to take more risks.
⑤ There are both biological and psychological explanations as to why some people may choose to take more risks than others. However, none of these explanations are definitive.
1. If a person has fewer active dopamine receptors.________.A.he is less likely to feel happy |
B.he is more willing to take risks |

6 . Many of China’s ancient architectural treasures smashed to dust before Lin Huiyin and Liang Sicheng began documenting them in the 1930s. The husband and wife team were among the first preservationists to operate in China, and by far the bestknown. Their efforts have since inspired generations of people to speak out for architecture threatened by the rush toward development.
Becoming China’s best architectural historians was no easy accomplishment. The buildings they wanted to save were centuries old located in distant parts of the country.In many cases, they had to journey through dangerous conditions in the Chinese countryside to reach them. Exploring China’s remote areas during the 1930s meant traveling muddy, poorly maintained roads by mule(骡子)or on foot. Inns were often dirty food could be polluted, and there was always risk or violence from rebels, soldiers and robbers.
Their greatest discovery was the Temple of Buddha’s Light, in Wutai County, Shanxi Province. The breathtaking wooden temple was built in 857 A. D., making it the oldest building known in China at the time.
Liang and Lin crawled into the temple’s most forbidding, forgotten areas to determine itsage, including one hideaway inhibited by thousands or bats and millions of bedbugs, covered in dust and littered with dead bats. “In complete darkness andamong the awful smell, hardly breathing, with thick masks covering our nosesand mouths, we measured, drew, and photographed with flashlights for several hours. When at last we came out to take a breath of fresh air, we foundhundreds of bedbugs in our bag. We ourselves had been badly bitten. Yet the importance and unexpectedness of our find made those the happiest hours of myyears hunting for ancient architecture.” Liand wrote of the experience in anaccount included in “Liang and Lin; Partners in Exploring China’s ArchitectualPast.”

The Dangerous Downsides of Perfectionism
In one of my earliest memories, I’m drawing. I don’t remember what the picture is supposed to be, but I remember the mistake. My marker slips, an unintentional line appears and my lip trembles. The picture has long since disappeared. But that feeling of deep frustration, even shame, stays with me.
That’s the thing about perfectionism, a crucially self-defeating way to move through the world. It makes you better at your career and relationships and life in general. Culturally, we often see perfectionism as a positive.
But the disadvantage of perfectionism isn’t just that it holds you back from being your most successful, productive-self. Perfectionistic tendencies have been linked to a long list of clinical issues: depression, social anxiety disorder, eating disorders, and most damaging of all, suicide (自杀).
“Based upon the 60-odd studies that we’ve done, the higher the perfectionism is, the more psychological disorders you’re going to suffer,” says York St John University’s Hill. “Factors often labeled ‘healthy’ perfectionism, like striving for excellence, aren’t actually perfectionism at all. They’re just conscientiousness (尽职尽责)—which explains why people with those tendencies often have different results in studies. Perfectionism isn’t interpreted by working hard or setting high goals. It’s that critical inner voice.”
Take the student who works hard and gets a poor mark. If she tells herself, “I’m disappointed, but it’s okay; I’m still a good person overall,” that’s healthy. If the message is, “I’m a failure. I’m not good enough,” that’s perfectionism.
Perfectionists can make smooth sailing into a storm, a brief ill wind into a category-five hurricane. Eventually, the behaviours perfectionists adapt, actually, do make them more likely to fail.

For Self-driving Cars, Car Washes are a Nightmare
Car washes have been automated for decades, but companies developing fully self-driving vehicles must rely on a human touch to keep their cars and trucks in working condition.
Avis, which has years of experience managing rental cars, has been tasked with cleaning and refueling the self-driving vans of Waymo, the self-driving arm of Google’s parent company. Avis chief innovation officer Arthur Orduña told CNN, “There are special processes that definitely require a lot more care and focus, and you have to clean the vans quite often.”
A.The sensors on a fully self-driving car require special care. |
B.Orduña wouldn’t reveal exactly how they’re washing the vehicles. |
C.The most advanced cars on the planet require an old-fashioned handwashing. |
D.Meanwhile, some companies, such as Cruise, are building sensor cleaning equipment into their vehicles. |
E.There are a range of problems with putting a self-driving vehicle through a traditional car wash, experts say. |
F.A self-driving vehicle’s external needs to be cleaned even more frequently than a typical car because the sensors must remain free of obstacles. |
