2 . There are multiple experiences a Westerner can describe as a “culture shock” in China, one of the fastest-growing economies, like eating mouthwatering baozi for breakfast. These experiences, however, paled in comparison to the one I experienced during my time in an organization I’ve been serving in for two years to provide free educational tours at my leisure — the advancement and equalizing of China’s known wealth disparity（差异）through the social network and cashless payment giant（巨头）, WeChat, which I rarely used before.
Last month, the organization led a thrilling trip to camp. Initially, we went through a village kept alive by the residents. The views there are so attractive and refreshing. Walking through endless red apple trees, I saw an elderly woman who gently offered to sell me apples. Unfortunately, I informed her I didn’t have cash on hand. She quickly told me to scan the QR code（二维码）on her phone, which in seconds would get my money into her bank account via WeChat. Needless to say, I was blown away. And of course, the apples were tasty.
As an advocate of financial growth opportunities in under-served communities, it was inspiring to witness that technology lets people contribute to the economy regardless of socioeconomic background in China. Though the socioeconomic problems remain to some extent, access to and adoption of technology creating financial opportunities transforms the lives of everyday citizens and enables communities to flower.
While I once didn’t believe a “cashless society” was possible and thought it could cause more unfavorable conditions, I now stand corrected. Perhaps it might take longer for New York City to adapt, as we lag behind in this transformation and there is so much we can learn. I also wonder what the human race can achieve when technology provides endless opportunities for people of all backgrounds to advance.

3 . To shoot a scene of people eating food, you need two different perspectives (角度). To record a bus journey to school, you need three quick cuts. To complete this short, morning rush-hour video blog – or “vlog” – you need four pieces of music.
With more than 90 million vlogs available online, and 2,000 posted every hour on the YouTube video-sharing site, CBS News says they are mainstream with people born after 1995.
“The most important thing about vlogging is to tell a good story. Other visual effects are auxiliary (辅助的),” wrote US vlogger Casey Neista, who has almost 10 million subscribers on YouTube.
Chinese vlogger Wang Xiaoguang is an example of a good storyteller. In one of his popular vlog posts, Wang tells the story of traveling to Japan. While there, he took a ride in the wrong direction and got lost. Worse, he forgot to bring a phone charger.
Another key aspect of vlogs is that the content is based on everyday life, according to Ouyang Nana, 18, a young Chinese musician. She documents her life at Berklee College of Music. Ordinary as vlogs are, as many as 15 million fans share her wows and woes (喜怒哀乐) on a daily basis.
There are popular vlogs for beauty, gaming, fashion, food and travel. Vloggers are learning new ways to experience the thrill of them.
| A．They come from all walks of life. |
| B．However, he didn’t take the number of his hotel. |
| C．Vlogging has taken China by storm over the past year. |
| D．Some other popular vloggers choose to show their careers. |
| E．Vlogs pave the way for future advertising and sales campaigns. |
| F．Luckily he was able to borrow money from a stranger and escape trouble. |
| G．Vloggers have these techniques in mind as they film their daily activities. |
4 . If you could change your child's DNA in the future to protect them against diseases, would you? It could be possible because of technology known as CRISPR- Cas, or just CRISPR.
CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part of DNA； it also uses an enzyme (If) that can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly.
The uses of CRISPR could mean that cures are developed for everything from Alzheimer's to cancer to HIV. By allowing doctors to put just the right cancer-killing genes into a patient's immune system, the technology could help greatly.
In April scientists in China said they had tried using CRISPR to edit the genomes (基因组)of human embryos. Though the embryos would never turn into humans, this was the first time anyone had ever tried to edit DNA from human beings. With this in mind, the US' National Academy of Sciences plans to discuss questions about CRISPR s ethics(伦理问题).For example? CRISPR doesn't work properly yet. As well as cutting the DNA it is looking for, it often cuts other DNA, too. In addition, we currently seem to have too little understanding of what DNA gives people what qualities.
There are also moral questions around playing God”. Of course, medicine already stops natural things from happening-for example, it saves people from infections. The opportunities to treat diseases make it hard to say we shouldn't keep going.
A harder question is whether it is ever right to edit human germ-line(种系)cells and make changes that are passed on to children. This is banned in 40 countries and restricted in many others. However, CRISPR means that if genes can be edited out, they can also be edited back in. It may be up to us as a society to decide when and where editing the genome is wrong.
Also, according to The Economist, gene editing may mean that parents make choices that are not obviously in the best interests of their children: “Deaf parents may prefer their children to be deaf too； parents might want to make their children more intelligent at all costs.
In the end, more research is still needed to see what we can and can't do with CRISPR. “It's still a huge mystery how we work,” Craig Mello? a UMass Medical School biologist and Nobel Prize winner, told The Boston Globe, "We're just trying to figure out this amazingly complicated thing we call life.
1. What is the passage mainly about?| A．What we can and can't do with CRISPR. |

5 . Financial Education-Awareness Dilemma
When it comes to financial education, the majority of today's youth will regard it as a necessity for certain specific people who want to make their career in the financial world.
Suppose you have $100 in a saving account that pays simple interest at the rate of 2%per year. lf you leave the money in the account, how much will you have accumulated after 5 years: more than $102, exactly $102, or less than $102? The test might look simple, but only half of the people surveyed gave the correct answer.
On the contrary, people who have a lower degree of financial literacy tend to borrow more, accumulate less wealth, and pay more in fees related financial products. They are less likely to invest, more likely to experience difficulty with debt, and less likely to know the terms of their mortgages and other loans. Thus, the cost of this financial ignorance is very high.
What is the solution?
| A．Financial education must start early. |
| B．However, they miss an important point. |
| C．Why does each of us have to face a financial challenge? |
| D．Why does financial literacy matter so much in our society'? |
| E．Rich people are generally better educated on financial management. |
| F．Besides, these people have more than double the wealth of people who don’t. |
| G．For example, they frequently make late credit card payments, overspend their credit limit, etc. |
A 15yearold boy planned to put a ball covered with petrol into his mouth and set it on fire. He would film the dangerous action and put it on YouTube. And, he hoped to become famous on the Internet. But things didn't go the way he imagined. His clothing caught fire, and he was rushed to the hospital with serious burns on his body.
YouTube hosts millions of videos of people attempting dangerous actions. Many of them are by kids and young adults. Some experts say that by hosting these videos, YouTube encourages young viewers to take deadly risks. Research by the Centers for Disease Control and Prevention shows that more than 180，000 Americans die from accidental injuries each year. That's one person every three minutes. More than 14，000 of those killed are kids under the age of 19. Is YouTube to blame?
People have always found it interesting to watch others try risky things. Audiences are mad about these kinds of things. Some of the earliest Greek comedies had characters followed by wild animals and knocking into walls. Now, in the age of the Internet, anyone with a camera and a YouTube account can create this kind of “fun”. Many viewers, especially teenagers, are influenced by what they see and want to try it themselves. “YouTube has taken the playing in the neighborhood to a worldwide level，” says Clair Mellenthin, a researcher from the Centers.
Supporters of YouTube argue that it isn't YouTube's responsibility to examine its content. “Parents should be the ones to make sure that kids are behaving safely，” they say. In fact, YouTube has a rule on content. For example, dangerous activities that have a risk of serious physical harm or death are not allowed. Staff of YouTube, carefully watch the website 24 hours a day, looking for videos that are against their rules. But is this enough?

7 . If you could have one superpower, what would it be?
Dreaming about whether you would want to read minds, see through walls, or have superhuman strength may sound silly, but it actually gets to the heart of what really matters in your life.
Every day in our work, we are inspired by the people we meet doing extraordinary things to improve the world.
They have a different kind of superpower that all of us possess: the power to make a difference in the lives of others.
We’re not saying that everyone needs to contribute their lives to the poor. Your lives are busy enough doing homework, playing sports, making friends, seeking after your dreams. But we do think that you can live a more powerful life when you devote some of your time and energy to something much larger than yourself. Find an issue you are interested in and learn more. Volunteer or, if you can, contribute a little money to a cause. Whatever you do, don’t be a bystander. Get involved. You may have the opportunity to make your biggest difference when you’re older. But why not start now?
Our own experience working together on health, development, and energy the last twenty years has been one of the most rewarding parts of our lives. It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead.
1. What does the underlined part in Paragraph 2 refer to?| A．Your life style. | B．Your life value. |
| C．Your trouble in life. | D．Your life experience. |
| A．They possess different kinds of superpowers. |
| B．They have got the power to change the world. |
| C．Some people around them are making the world better. |

| B．Rising above self and acting to help others. |
| C．Working hard to get a bigger opportunity. |
| D．Trying your best to help the poor. |
8 . Walmart will soon use 360 robot cleaners across a few hundred of its stores. Using maps input by human employees, the AI-powered cleaners will travel in the store with no difficulty, sweeping the floor--just as human employees used to do.
Perhaps the most striking thing about these robot workers is how not-striking they are. Sci-fi movies suggest a future full of human-like robots who appear with their horrible qualities. Now the future is coming into view, and it looks like a giant lie. It's easy to imagine walking past an Auto-C on a shopping trip without even noticing its presence.
AI has already started to become a part of our everyday life. In New Jersey this week, dozens of workers were hospitalized after a robot at an Amazon fulfillment centre accidentally broke a can and enveloped workers in eye-and-lung-damaging gas. Days earlier in California, an auto-piloted Tesla drove a drunk, sleeping driver down a highway, which no doubt did some potential risk to the other drivers on the road. Highway patrol officers figured out on the spot how to stop the AI car.
Of course, industrial accidents and drunk drivers existed well before AI. Tools with the power to release the burden of physical labor—horses, steam machines, self-driving cars—also come with the power to injure. And the presence of AI-powered machines just steps away from us is, for now, still a rare thing for most people.
But the nature of robots’ coming into our daily life lives will make it harder to recognize—or object to—the bigger changes they bring later. Walmart insists that the robot cleaners give employees more time for customer service and other tasks. Critics point out that they could just as easily become an excuse to reduce staff and wages.
1. What is the difference between sci-fi movies and the reality?| A．Now the human-like robots is hard to recognize. |
| B．Now people don’t go to see the sci-fi movies. |
| C．Now the human-like robots can tell lies. |
| D．Now it is easy to ignore the robots. |
| A．They damaged the robot first. |
| B．The robot caused an accident on purpose. |
| C．The robot made a mistake by chance. |
| D．The robot driving them on the highway had an accident. |
| A．Supportive | B．Objective | C．Doubtful | D．Indifferent |
| A．Artificial intelligence is bringing great effect to our daily life. |
| B．Walmart will soon use 360 robot cleaners across its stores. |
| C．We should say no to artificial intelligence. |
| D．Artificial intelligence is dangerous to our life. |
9 . Our world is more connected than ever before thanks to technology.
You should be determined to actively end your loneliness. We often end up passively waiting for someone else to make us feel less lonely. You may feel that your loneliness indicates that nobody is willing to connect with you. And there is nothing you can do about it. But that is far from the truth.
You should find reasons why you are lonely. We all feel lonely for different reasons. Some of us have no one else to interact(互动) with on a consistent basis and that's why we feel lonely. You may feel that the people in your life don't share your thoughts and ideas.
You should find people who share your interests.
| A．Whatever the reason is |
| B．Whether it's coin collecting or video games |
| C．If you have no reason to share your interests |
| D．You should be true to yourself or actively end loneliness |
| E．You should be open about your thoughts, ideas and desires |
| F．Ending loneliness is something that you can and should do actively |
| G．However, more and more of us find ourselves having to stand loneliness |
10 . It was an autumn day, and 1 was standing in the kitchen, hanging my head over the counter and trying to figure out how many calories were in a bowl of homemade yogurt and fruit. And I felt annoyed.
I was 16, and my best friend and I had gone to our first Weight Watchers meeting. It was the trend in the mid-1980s，and even though I was an athlete, like many teen girls, I didn't necessarily like what I saw in the mirror. But after a week or so of recording every meal and snack and calculating the calories, I had had enough. I went back to my routine of chowing whatever I wanted, running and skiing, and let that be that. And it's still pretty much what I do; as long as the workouts are regular and the food is whole and balanced, my body's set point hasn't varied for years.
The weight loss trend of three decades ago−full of scales and counting calories−has fallen away. Now fasting is popular. The ways to keep fit vary: on the 5:2 diet a person eats for five days and fasts for two days each week, while the 18:6 refers 10 fasting for 18 hours and then eating within a six-hour window each day.
In this issue, Associate Editor Mark Barna tries to understand the science behind the fasting plans. Researchers have found that animals like monkeys age more slowly after years of eating less, and in the lab in humans, they saw improvements in a number of signs that indicate risk of some hard to cure diseases. The hope for healthy weight loss isn’t over yet, but at least now the calculators don’t have to be out at every meal.

| B．There were too many calories in the yogurt and fruit. |
| C．The Weight Watches meeting was not necessary for her. |
| D．She had to work out the calories in every meal and snack. |
| A．Eating. | B．Doing | C．Cooking. | D．Choosing. |

| C．They fast daily or weekly. |
| D．They eat enough every day. |
| A．People grow more slowly if they eat less. |
| B．People are healthier if they eat less. |
| C．People have stopped losing weight now. |
| D．People calculate their food for every meal. |
