1 . America’s youth is turning its back on tobacco. According to a study recently published by the Centers for Disease Control and Prevention (CDC), cigarette smoking among US high school students is at an all-time low. One in 5 US high school students in 2016 reported using a tobacco product within the past 30 days, an improvement from 1 in 4 students just one year before.
“These findings show the importance of continuing to implement the evidence-based strategies that we now work to reduce all forms of tobacco product use, including e-cigarettes, among our nation’s youth,” says Brian King, of the CDC’s Office on Smoking and Health and senior author of the study.
And it’s not just tobacco: Drug use among US teens is down across the board. The National Institute on Drug Abuse has published annual reports on US teens’ drug use since 1996, and the 2016 survey shows the lowest rates of illegal drug and alcohol use. Marijuana (大麻) use remained “mostly steady”. “It is encouraging to see more young people making healthy choices not to use illegal substances,” says former National Drug Control Policy Director Michael Botticelli.
All individual forms of tobacco such as cigarettes, e-cigarettes, cigars, and smoke-less tobacco saw declines in usage in 2016. Experts are especially encouraged by the decline in cigarettes, the most popular tobacco product among teens. In 2016, 11.3 percent of high school students reported using e-cigarettes, down from 16 percent in 2015.
Dr. King says adaptation is key to the decline of e-cigarettes. “We have over a half-century of science telling students about the harmful effects of tobacco use and what works best to prevent it,” says King. “E-cigarettes are the most commonly used tobacco product among our nation’s youth, and it’s critical that our proven strategies are modernized to keep pace with the changing tobacco product landscape.”

3 . Everywhere I look, there are new buildings under construction. The neighborhoods that I knew as a boy, filled with beautiful old buildings, have mostly disappeared, and in their place, modern, high-rise buildings have appeared. There is good reason for this. Residents want all the conveniences of modern living. However, how can our children understand and maintain their cultural identity if we erase so much of the physical evidence of it?
The arguments for preserving historic buildings are not simply about an emotional attachment to the past. There are also good economic arguments in favour of preservation. The renovation (修缮) and preservation of historic districts can become an economic engine, drawing tourists and small businesses to the area. For example, in Dubai, the historic Al Bastikiya district draws thousands of tourists every year from all over the world. It also attracts local residents, eager to learn about their city's past.
Some have argued that historic preservation is too expensive, but many recent projects have demonstrated that this is not necessarily the case. In fact, renovation of an existing structure for adaptive reuse can cost about £40 per square metre less than even the most basic new construction, while preserving the beauty of the original building. And, although it is often claimed that old buildings have a more significant environmental footprint than new construction because they aren’t very energy efficient, architects and environmental experts maintain that the greenest building is the one that is already built. New construction almost always has a more serious environmental impact (影响) because it requires the use of all-new materials that must be transported, often over long distances, instead of recycled materials that are already on site. We recycle so many other things. We can and should recycle buildings, too.
Historic preservation is an option that opens many possibilities; demolition (拆毁), in contrast, is irreversible. Once these treasures are lost, they are lost forever, an important link in our heritage that can never be recovered.

4 . In the days before the Internet, critical thinking was the most important skill of informed citizens. But in the digital age, according to Anastasia Kozyreva, a psychologist at the Max Planck Institute of Human Development, and her colleagues, an even more important skill is critical ignoring.
As the researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with a lot of emotional and eye-catching stories while providing little useful information, so they can expose us to profit-generating advertisements. Therefore,we are no longer customers but products, and each link we click is a sale of our time and attention. Toprotect ourselves from this, Kozyreva advocates for learning the skill of critical ignoring, in which readers intentionally control their information environment to reduce exposure to false and low-quality information.
According to Kozyreva, critical ignoring comprises three strategies. The first is to design ourenvironments, which involves the removal of low-quality yet hard-to-resist information from around. Successful dieters need to keep unhealthy food out of their homes. Likewise, we need to set up a digital environment where attention-grabbing items are kept out of sight. As with dieting, if one tries to bank onwillpower not to click eye-catching “news”, he’ll surely fail. So, it’s better to just keep them out of sightto begin with.
The next is to evaluate the reliability of information, whose purpose is to protect you from false and misleading information. It can be realized by checking the source in the mainstream news agencies which have their reputations for being trustworthy.
The last goes by the phrase “do not feed the trolls.” Trolls are actors who internationally spread false and hurtful information online to cause harm. It may be appealing to respond to them to set the facts straight, but trolls just care about annoying others rather than facts. So, it’s best not to reward their bad behaviour with our attention.
By sharpening our critical ignoring skills in these ways, we can make the most of the Internet while avoiding falling victim to those who try to control our attention, time, and minds.

5 . A new study by scientists at Utrecht University concludes that about half of global wastewater is treated, rather than the previous estimate of 20%. Despite this promising finding, the authors warn that treatment rates in developing countries are still very low.
Humans and factories produce vast quantities of wastewater per day. If not properly collected and treated, wastewater may severely threaten human health and pollute the environment.
The authors use national statistics to estimate volumes of wastewater production, collection, treatment and reuse. “Globally, about 359 billion cubic metres of wastewater is produced each year, equivalent to 144 million Olympic-sized swimming pools,” says Edward Jones, PhD researcher at Utrecht University. “About 48 percent of that water is currently released untreated. This is much lower than the frequently announced figure of 80%.”
While the results show a more optimistic outlook, the authors stress that many challenges still exist. “We see that particularly in the developing world, where most of the future population growth will likely occur, treatment rates are falling behind,” Jones explains. “In these countries, wastewater production is likely to rise at a faster pace than the current development of collection and treatment basic facilities. This poses serious threats to both human health and the environment.”
The main problem, especially in the developing world, is the lack of financial resources to build basic facilities to collect and treat wastewater. This is particularly the case for advanced treatment technologies, which can be extremely expensive. However, the authors highlight potential opportunities for creative reuse of wastewater streams that could help to finance improved wastewater treatment practices.
“The most obvious reuse of treated wastewater is to increase freshwater water supplies,” Jones states. Treated wastewater reuse is already an important source of irrigation water in many dry countries. However, only 11% of the wastewater produced globally is currently being reused, which shows large opportunities for expansion.
“But freshwater increasing is not the only opportunity,” says Jones. “Wastewater also has large potential as a source of nutrients and energy. Recognition of wastewater as a resource, opposed to as ‘waste’, will be the key to driving improved treatment going forward.”
However, the authors stress the importance of proper monitoring of wastewater treatment factories, accompanied by strong legislation (法律) and regulations, to ensure that the reuse of wastewater is safe. The authors also acknowledge public acceptance as another key barrier towards increasing wastewater reuse.

6 . How to Deal with FOMO in Your Life
FOMO, or “fear of missing out,” is becoming increasingly common and can cause significant stress in your life. It applies to anything from a party to a promotion at work and affects just about anyone. It always involves a sense of helplessness that you are missing out on something big.
With social media becoming popular, FOMO has become more obvious. As more research on FOMO is conducted, we are getting a clearer picture of how it affects us.
Moreover, one study found that the fear of missing out was linked to a greater smartphone and social media usage.
Rather than trying to connect more with people on social media, why not arrange to meet up with someone in person? Making plans with a good friend, or doing anything social that gets you out with friends can be a nice change of pace.
| A．It can help you to shake that feeling that you are missing out. |
| B．The idea that you might be missing out on a good time is not new. |
| C．Rather than focusing on what you lack, try noticing what you have. |
| D．The picture is not pretty, as there are many negative effects of FOMO. |
| E．Smartphone usage was related to fears of negative evaluations by others. |
| F．Smartphone and social media have made the FOMO phenomenon worse. |
| G．Understanding where the problem lies can be a great first step in overcoming it. |

9 . Technology has changed our lives and reshapes the way we live. Some of us love it and some of us are frustrated (懊恼的) with it. This is clear as most of us are guilty of being addicted to the Internet and social media.
The invention of airplanes, ships and spacecraft always allows people to visit other countries and even other planets. As long as we follow the laws of immigration, we can go to any country we like.
In addition, technology is also used by a large number of teachers to improve their teaching. It can make the lessons more interactive and interesting for students. E-learning is possible with the use of the Internet connection and computers. People wishing to study for a degree can do so at their comfortable homes.
However, we have to say that technology can be a double-edged sword. Nowadays, instead of paying attention to the conversation we are having face to face, we just take the phone. We are distracted by smartphones and technology in general. But we can’t blame technology. We should not blame ourselves, either.
| A．This gives students flexibility. |
| B．What we need to do is to find some balance. |
| C．This makes it easy for students to make progress. |
| D．Nevertheless, we have seen some benefits of technology. |
| E．When it comes to shopping, technology is also of great help. |
| F．Besides, we have suffered a lot from modern communication. |
| G．And of course, travelling can make people’s lives more colorful. |
10 . Many of us are lonelier than ever. We can go shopping and avoid speaking to a single person. Automated voice son phones and machines suck the contact and relational element out of day-to-day life, so much so that experts say that we are experiencing a loneliness disease.
According to Dr. Lalitaa, loneliness is the feeling we get when our need for rewarding social contact and relationships is not met. But loneliness is not always the same as being alone. Loneliness is a state of mind linked to wanting human contact but feeling alone. People can be alone and not feel lonely, or they can have contact with people and still experience feelings of loneliness.
Loneliness is a universal human emotion that is both complex and unique to each individual. There are many contributing factors to loneliness, such as illness, relationships breaking down, moving country, changing jobs or not being understood by co-workers, retiring, starting university, etc.
We cannot underestimate the impact loneliness can have on our physical and mental wellbeing. According to research, loneliness has comparable health risks to smoking 15cigarettes a day, and people who feel lonely are more likely to die earlier and suffer from heart attacks. Dr. Lalitaa says, “People often say to me, ‘It’s too late to meet new people as an adult.’ Having human connect ion can look different for each person, but this can become a block, stopping them going out, trying new things and connecting with new people. Remember, it is never too late to make good, meaningful connections.”
However, don’t put pressure on yourself. A meaningful relationship takes time. It is not just created overnight. Also, take some time to sit with yourself and venture (冒险) into some of the things that you like doing. “The first thing I would say is not to deny or distance the feeling. Acknowledge it and then you can choose to focus on ways to help yourself,” says Dr.Lalitaa.
