1 . Nowadays some companies are attempting to grow seafood from cells in a laboratory rather than harvesting it from the oceans.
With massive problems with overfishing worldwide and growing demand for shrinking supplies of seafood, the way fish currently makes its way to our plates isn't a long-term viable option. Between 1961 and 2016, the average annual increase in global food fish consumption outpaced population growth. Those are figures not sustainable for us, the fish or the environment as a whole.
Cellular seafood could be the answer. Just don't make the mistake of calling it lab-grown fish. ''None of us in the industry would call it lab-grown seafood, '' says Mike Selden, CEO of Finless Foods. ''Finless Foods isn’t lab-grown. We experiment and create our science in the lab, but don't produce there. Our products come from a production base much like a farm as a production base for animals.''
Finless Foods is a tech company in San Francisco. Beginning in 2017, it's been working to bring to market a species of cultured bluefin tuna (蓝鳍金枪鱼) created using cellular technology. Shortly after that, the company produced its first pound of bluefin tuna meat for a cost of about $19,000. Since then, however, it's been working to bring that price down.
Selden terms what Finless Foods is doing as ''cell-based seafood''. ''We're growing seafood from real seafood cells,'' Selden explained. ''We take cells from a fish once, and then grow them endlessly from that. We do the same process that happens inside of a fish and make it happen outside of a fish. ''
The goal of cellular seafood isn't to entirely destroy the current seafood industry. Instead, it's intended to augment it—and perhaps to help reduce some of the more harmful aspects of current fishing practices like overfishing and illegal fishing. And when it comes to certain sea species, this laboratory-based approach could help create a plentiful supply of certain fish without endangering the survival of certain overfished species as a whole.

5 . The world’s top automakers are increasingly offering more electric vehicle models. This growth is expected to continue， with more people choosing to hit the road with clean-running electric- powered cars.
Environmentalists have praised the automakers for taking major steps to limit harmful pollutants linked to worldwide climate change. But electric vehicles are also known for not producing another kind of pollution—noise. They run on batteries instead of fuel， and can operate in silence.
While many people might consider this a good thing， quiet cars can also cause problems. The main danger is that people walking in areas around electric vehicles face a greater risk of being hit if they cannot hear the cars coming.
Governments in the United States and Europe have recognized this problem. So， they have set requirements for manufacturers to add warning sounds to vehicles operating on electricity.
The U.S.Department of Transportation finalized its rules a year ago. The rules require electric and hybrid (混合能源) vehicles to be equipped with some kind of warning sound when moving at speeds up to 30 kilometers per hour. The rules are aimed at preventing injuries among people walking or riding bicycles and to protect the blind.
So what kinds of sounds can we expect to hear from the next generation of electric vehicles? One of the easiest solutions would be for carmakers to simply reproduce the sound a car would make if it actually did run on fuel. But many industry officials believe this would be a mistake.They say this would not support the electric vehicle’s true identity. It would also limit great possibilities to link the car’s sound to a whole new image, which could help increase sales.
Frank Welsch is head of technical development at Germany’s Volkswagen. He said that finding the perfect sound mix is not an easy process. “The electric vehicle sound is its identity,” he said. “It cannot be too annoying. It cannot sound like anything we had in the past.”
An official from Mercedes-Benz said the sound was designed to provide a safe warning without annoying passengers inside the vehicle. He said the goal was to create a car that remains completely quiet on the inside, but fills the sound requirements and supports the model’s image on the outside.
It might seem strange to think that part of our automotive future is currently being developed in the same kinds of recording studios used by musicians. But that is exactly what is happening.

7 . Never Talk to Strangers?
“Never talk to strangers.” Many children are taught this simple rule as a precaution against abduction (诱拐). In June, 2005, an 11-year-old boy was lost in the Utah wilderness for four days. During that time, he stayed on the path. He saw people searching for him but deliberately hid from them, afraid someone might “steal” him. Eventually, the unfortunate game of hide-and-seek ended and he was found. According to the Canada Safety Council, this alarming incident shows how unwise it is to instill (灌输) a fear of strangers in children. The “stranger danger” message can prevent children from developing the social skills and judgment needed to deal effectively with real-life situations. In a difficult situation, a stranger could be their lifeline to safety.
To have a child go missing is a parent’s worst nightmare. The threat of abduction by a stranger is minimal when compared with other possible reasons for a disappearance. In 2004, there were 67,266 missing-children cases in Canada. Only 31 involved abduction; in most of those cases the abductor was a relative, friend, or person known to the family. There were 671 cases of children wandering off, and 332 cases of abductions by a parent. Almost 80 percent of all cases were runaways. These statistics cast doubt on the idea that children should never talk to strangers. Wandering off is more common—but a lost child may have to call upon a stranger for help, and must develop the ability to judge what kind of people to approach. The “never talk to strangers” rule does not protect children in the situations they are most likely to face. On top of this, it can be confusing. Adults do not model the behavior; they often talk to strangers. A child may not know how to tell who is a stranger, and who is not.
For young children, nothing replaces close supervision (监管). Pre-schoolers do not understand risk and tend to act without thinking. Children need to develop habits and attitudes that will protect them from the real threats and dangers they may face. The Canada Safety Council encourages parents to give their children age-appropriate positive messages about safety, bearing in mind how youngsters may understand their world.

8 . Rich and Famous
Twenty years ago the most common ambition of American children was to be a teacher, followed by working in banking and finance, and then medicine. But today’s situation is quite different.
According to experts, young people desire these jobs largely because of the wealth and the fame.
In spite of these disadvantages, there is greater ambition than ever among young people to achieve that status. They are not satisfied just making a living—they want to be rich and famous. Globally, more and more TV shows provide talent competitions where winners can achieve their goals in just a few weeks or months.
While many people argue that there is nothing wrong with having such ambitions, others feel that this trend will finally lead to dissatisfaction as more and more people are unable to reach their goals.
| A．In many ways this has been brought about by the celebrity culture. |
| B．People no longer have a sense of satisfaction once their goals have been achieved. |
| C．Besides, it can be difficult for them to adapt back to a normal everyday life. |
| D．The younger generation don’t favor these professions any more. |
| E．Unfortunately, they do not always have a positive effect on people’s life. |
| F．The reason is that they don’t realize it takes talent and hard work to be rich and famous. |

9 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.
What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.
Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t
even exist if it weren’t for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. ＂Almost every great love story and each big business deal begins with small talk,＂ he explains. ＂The key to successful small talk is learning how to connect with others, not just communicate with them.＂
In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. ＂It’s not that talking to the waiter is better than talking to your husband,＂ says Dunn. ＂But interactions with peripheral(边缘的) members of our social network matter for our well-being also.＂
Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. ＂Small talk is the basis of good manners,＂ he says.
