1 . The world food safety could be in danger because of a number of food production shocks (冲击), according to an Australian study.
The researchers from the University of Tasmania found that there were 226 shocks in the area of food production across 134 nations and the frequency has been increasing over the past 50 years.
According to Cottrell, a researcher from the University of Tasmania, the main causes behind the shocks are different. For crops, extreme weather events such as floods and no rain for a long time play the biggest part. Weather also plays a role in livestock(家畜)production, but disease plays a bigger role. Disease also leads to aquaculture(水产业)shocks, while in the ocean most of the food shocks are caused by overfishing.
“When we look at the food production systems, covering crops, livestock, fisheries and aquaculture,” Cottrell said, “we find that crops and livestock are more easily affected than aquaculture. And some countries in South Asia are more frequently affected than others.”
The effects of production shocks reached far away from where they happened. When one means of food production is greatly reduced, it will cause unexpected results. “The India got a lot of food production shocks in crops and livestock, largely because of floods,” Cottrell explained. “If countries like India are shocked and the rice production is much smaller, they’ll probably send less goods to another country. And that shock suddenly starts to affect all the trade partners of the major producers as well.”
According to what Cottrell said, while the international community faces a great challenge to these problems, steps taken now can help fight against unexpected shocks in the future. “This can be done through measures such as food store systems so that they are better able to deal with the effect which is caused by problems such as climate change.” said Cottrell.

2 .
Chen Chen is 8 years old. For the Spring Festival this year he was given an iPad as a present and never goes anywhere without it.
Many children in China are suffering the same problem:
“There are about 30 shortsighted children coming every day,” said Hu Dali, a doctor at Guiyang Aier Eye Hospital. “Half of those children are suffering from reduced vision because they have played with mobile phones and iPads for too long.”
Experts say children’s version is not yet fully developed and their eyes get tired more easily.
The iPad uses a very bright LED backlight. A user’s pupils (瞳孔) have to keep getting used to the new light levels. If children stare at an iPad screen for a long time, their eyes do not have time to rest.
Experts suggest that users should hold their iPad between 40—60 centimeters away from them. The brightness of the screen should be made comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.

3 . You know the feeling — you have left your phone at home and feel anxious, as if you have lost your connection to the world. “Nomophobia” (无手机恐惧症) affects teenagers and adults alike. You can even do an online test to see if you have it. Last week, researchers from Hong Kong warned that nomophobia is infecting everyone. Their study found that people who use their phones to store, share and access personal memories suffer most. When users were asked to describe how they felt about their phones, words such as “hurt” (neck pain was often reported) and “alone” predicted higher levels of nomophobia.
“The findings of our study suggest that users regard smartphones as their extended selves and get attached to the devices,” said Dr Kim Ki Joon. “People experience feelings of anxiety and unpleasantness when separated from their phones.” Meanwhile, an American study shows that smartphone separation can lead to an increase in heart rate and blood pressure.
So can being without your phone really give you separation anxiety? Professor Mark Griffiths, psychologist and director of the International Gaming Research Unit at Nottingham Trent University, says it is what is on the phone that counts — the social networking that creates Fomo (fear of missing out).
“We are talking about an Internet-connected device that allows people to deal with lots of aspects of their lives,” says Griffiths. “You would have to surgically remove a phone from a teenager because their whole life is ingrained in this device.”
Griffiths thinks attachment theory, where we develop emotional dependency on the phone because it holds details of our lives, is a small part of nomophobia. For “screenagers”, it is Fomo that creates the most separation anxiety. If they can’t see what’s happening on WeChat or Weibo, they become panic-stricken about not knowing what’s going on socially. “But they adapt very quickly if you take them on holiday and there’s no Internet,” says Griffiths.

4 . Justice is something we all desire, and the hope is that our legal system can be fair. In the past, people often saw injustices taking place that went unpunished. Some of these people got fed up, took matters into their own hands, and became vigilantes (治安员). They played the role of judges, jury and executioners (执行者). Today, the same thing is happening on a much larger scale, and it is known as Internet vigilantism.
Internet vigilantism works by first identifying a person who has committed a crime or done something that is considered uncivil.
Our modern age that is filled with digital cameras has made injustice easy to record, and the Internet has made it easy to distribute the evidence instantly. This method has been successful in many cases for tracking down people who have committed crimes. It also has been very helpful in keeping those with power in check. Keeping power in check is the upside of distributing evidence only if justice is reached through proper channels.
However, there are two sides to Internet vigilantism. When Internet citizens gang up on people for minor crimes or small faults, those who are the focus of the gangs can have their lives ruined. The vigilantes gather information on the Internet and use it to publicly shame the person. The accused person thus loses all his or her rights to privacy and everything about him or her is brought out into the open. Internet vigilantism violates basic human rights to privacy and can cause serious damage to people or their reputations.
Another problem is that it also has a negative effect on the friends and family members of the person being shamed. Innocent people with the same name as the accused can also get caught in the cross fire. Worst of all, the person being targeted rarely gets a chance to defend himself or herself.
We need to ask ourselves how far we will go to punish someone and how much privacy they deserve. When it comes to Internet vigilantism, remember that it is very easy to post an opinion or video anonymously (匿名地) online and give a one-sided or partial account of the truth. Like so many other aspects of life, we must resist passing judgment before fully understanding a situation.

5 . Thirteen-year-old Kaylee has a lot of friends — 532, actually, if you count up her online friends. And she spends a lot of time with them.
But is it possible that Kaylee’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.
Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not Words With Friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.
Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platforms (平台).
In fact, in many ways, online communication can make friendships stronger, “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.
Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual words, we will have little time for our real-world friendships.” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need someone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

7 . Dorothy Lee and her husband were driving home from a study group one night when their car suddenly hit something. Mrs. Lee looked at her husband, who was driving, and saw his head move down and up several times and fall. In the next minutes Mrs Lee managed to avoid a serious accident while stopping the car, called 911 on her cellphone and tried to make her husband come back to life before an ambulance arrived. But at the hospital, soon after learning her husband had died of sudden heart trouble, Dorothy’s heart appeared to give out as well. She experienced sudden sharp pains in her chest (胸腔), lost senses and knew nothing.
Doctor’s of that hospital were surprised at finding: There wasn’t any evidence of heart trouble. Finally, doctors thought that Mrs. Lee had suffered from a broken-heart syndrome (伤心综合症). The disease looks like heart trouble, but appears to have little connection with heart trouble. It is caused mainly by stress and other strong feelings. The disease is uncommon, making up for about 1% to 2% of people — and about 6% of women — who are likely to suffer such sudden heart trouble. It can be very dangerous sometimes, but for the most part patients recover quickly, with no lasting damage to their hearts.
If patients are hospitalized with the broken-heart syndrome, their hearts might be beating as little as 20% of what it should work. But within 48 to 72 hours, many recover to the 60% level that is considered healthy. It is uncommon.
Mrs. Lee’s heart was so weakened by her husband’s death that she nearly died. The 63-year-old woman needed a special balloon pump (球囊泵) during the first days in the hospital. But in spite of warnings by her doctors, she attended her husband’s funeral (葬礼) five days later.
1. What can we learn about the accident?| A．The husband died in it. | B．The wife died later in the hospital. |
| C．The husband died because time was wasted. | D．The husband died of heart trouble after it. |
| A．Her bad health. | B．Worry, anxiety and sadness. |
| C．Her seriously damaged heart. | D．The aging of the heart. |
| A．She was calm in case of emergencies. | B．She was unhealthy but strong minded. |
| C．She was easily hurt and moody. | D．She was caring and generous. |
| A．The broken-heart syndrome is less common among women. |
| B．Patients with the broken-heart syndrome can recover by themselves. |
| C．The broken-heart syndrome could come and go both quickly. |
| D．Most people may suffer from the broken-heart syndrome. |
8 . Most college students think that there are only two choices after graduation—finding a job or entering graduate school. An opportunity that is often missed is volunteering with an organized volunteer program.
Volunteering provides a year of intention (计划) in a community where recent graduates can learn about the world they are entering, about themselves as individuals (个体) and about their role in this world. It provides intentional time to understand the purpose that drives one as an individual in life. Taking a year off after graduation to volunteer allows students to slow down and really understand where they want their future to lie. Not only this, but students will also be helping others, getting work experience, living in a community and giving back to society.
Volunteering often leads to a job opportunity. A volunteer might stay and work with the organization, shifting from a volunteer position to a paid position. For example, an individual doing volunteer teaching with an organization might be offered a teaching position at their school. Even if the volunteer position does not lead to a paid position, the volunteer should keep in touch with their organization. One reason is that the organization can write letters of recommendation (推荐) for the volunteer’s job applications. What’s more, volunteer experience on a resume could catch the attention of schoolmates from the organization or program who work at a place of employment (雇用). A shared volunteer experience with the manager might help one find a job!
Volunteers have fun together and like helping others a lot. They share a common mission and vision (使命和愿景), continue personal and professional development, and get new ideas about the world around them. They get to know the community, practice their social responsibility, and build their skill set and network with others. Even if volunteers are not paid, they receive these and many other benefits through their service.

9 . In today’s world of fast-paced games and short videos, people are spending less and less time on things. For example, research has shown that the average visitor spends just 15 seconds on a website before moving on to other things. But the Internet is a huge and busy place, with millions of sites to choose from. You might expect people to slow down a bit more when they’re in museums full of great works of art. But you’d be wrong.
Several studies have shown that the amount of time for people to spend looking at a piece of art is ten seconds. Many people may spend more time, but not much more — the average is about 28 seconds. At the Tate Modern Museum in London, it’s even worse. People there spend an average of just eight seconds on each artwork. And in that short period of time, the visitors are also managing to do another important thing — take selfies !
In recent years museums have been working to change this behavior. Today, over 170 museums around the world are celebrating “Slow Art Day”. They are asking their visitors to spend at least 5-10 minutes looking at just one work of art. Slow Art supporters believe that when visitors spend more time looking at and studying the work of art, they admire it more. Studying a work of art for more time can also help people get a better understanding of the artist’s ideas and what the artist went through to create the work.
Most of the museums taking part in Slow Art Day are choosing just a few works for their visitors to see. Some of the museums are offering chances for visitors to talk about the artworks and share their ideas.
1. Generally speaking, people spend ______ on each piece of art in a museum.| A．8 seconds | B．10 seconds | C．15 seconds | D．28 seconds |
| A．Admiring each artwork thoroughly. | B．Taking selfies in museums busily. |
| C．Celebrating “Slow Art Day” widely. | D．Looking at each artwork hurriedly. |
| A．To attract more people to visit the museums |
| B．To stop visitors from taking selfies inside |
| C．To make people spend more time on each artwork |
| D．To give visitors an opportunity to relax themselves |
| A．Museums on the Rocks: Please Advise! |
| B．Museums: Slow down to Admire more! |
| C．Slow Art Day: a Fruit of Museums! |
| D．Museums: an Escape from the Fast-paced Life! |
10 . By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friend’s new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?
Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choices. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.
Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.
Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.
Also, what you carelessly post on the Internet can come back to trouble you. Revealing (泄露) personal information on social sites can make users vulnerable (易受伤害的) to crimes like identity theft, stalking, etc. Many companies perform a background check on the Internet before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.
Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.
1. Paragraph 2 mainly shows that social networks ________.| A．help students finish their homework | B．offer professionals good chances |
| C．benefit users in various ways | D．guide users to make right choices |
| A．forbid the use of social networks during work time |
