2 . Is It Worth Buying Organic Food?
Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.
The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

3 . Vehicles on our roads are now mostly petrol and diesel (柴油) cars, but their days cannot continue for much longer. A recent university study found that current electric cars could be used for 87 percent of daily car journeys in the US. That figure could rise to 98 percent by 2020.
One hurdle to the widespread adoption of electric cars has been “range anxiety” — drivers concerns about running out of electricity on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.
Attitudes towards electric vehicles have changed greatly over the last few years. Not that long ago, electric cars were met with distrust, and their high prices drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade picky consumers. Plug-in cars will soon give internal combustion engine (内燃机) models a run for their money.
As well as development on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make commercial electric flight a reality.
Electric vehicles do not produce any emissions (排放). If the US could replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 percent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim (声称) to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

5 . There are people for whom the motivation lies in their family’s or companions’ duties. For some people, the purpose lies in a soul’s spiritual awakening. Brent Clayton, a firefighter by profession, is such an individual who found his purpose early in life and kept working to fulfill it.
Born on March 3, 1984, Clayton hugely felt the need to serve others. He followed his mission in life and acquired his diploma in Public Safety. He gradually realized the importance of securing people’s lives, which strengthened his faith in his mission. Clayton further pursued his bachelor’s degree from the University of Melbourne and master’s degree from Federation University. Then, Clayton worked in the military for a period before moving into a role with the prison service as a prison guard, the youngest person to ever be employed by the service at the time.
After spending a decade in the fire service including training and recruitment, he gained enough experience to become Australian most prominent fire service recruitment expert. Clayton devoted many years of his life to the firefighter recruitment process and fire service industry. He wanted people to realize the true value of this profession by establishing its significance. To communicate his perspective, Clayton established Fire Recruitment Australia in 2009. He aimed to train the next generation and prepare them for the future. Clayton used his experience and years-long training to prepare candidates who were as enthusiastic about the well-being of the world as him.
Keeping the point in mind, Clayton wrote the book Fire Service Recruitment-The Process to Success. His idea was to join his learning into an accessible medium so others didn’t have to waste years wondering what to do when applying to become a firefighter. After the success of the book, Clayton introduced candidates to a comprehensive test preparation and learning suite to facilitate success throughout each stage of the selection process. This platform helped him as well as his candidates to work together for the betterment of themselves and society at large.

6 . In the past decade, the use of social media has grown in a way that no one could have guessed. It has turned some teenagers into celebrities and turned the famous into the infamous, overnight.
A key feature of social media, however, is its volatility. Trends come and go, disappearing almost as quickly as they appeared.
Short video apps such as TikTok and its Chinese equivalent (等同物) Douyin, took the world by storm. The Telegraph reported that TikTok was ranked 8th on Apple’s App Store in April. And Douyin had more than 300 million domestic monthly active users in June, CNBC said.
Why are these short videos — which are rarely longer than a few minutes — so popular? Jiang Yige, Singapore-based analyst at FengHe Fund Management, has a theory. “Short videos are just right to fill in the little gaps in our busy schedules,” he told CNBC.
These videos — apart from being very convenient — are important to teenagers because they allow them to express themselves, according to Teen Vogue.
Liza Koshy, a user of the US app Musical, who has over 2 million followers, said, “The sense of community that users of short video apps get is another appealing feature.”
Live streaming (直播) is a feature of our social media life that now seems as natural as sunrise. It’s a pretty neat idea: You can watch anyone, anywhere, live. However, China has taken live streaming to a whole new level. In China, more than 100 million viewers monthly watch a live streaming video. Forbes thought that a number of factors had led to the popularity of the live streaming. Among them is viewers’ ability to interact with unknown names.
However, the quick development of social media may be having side effects too. Fake news is one serious problem it causes. Materials shared on these platforms are often not checked for accuracy. The most basic content can be false and can mislead users one way or another. We use social media all the time, which doesn’t mean that we understand the influence it is having on us. We should be mindful of both the time we spend on it and its impact on our minds.
1. What does the underlined word “volatility” in Paragraph 2 possibly mean?| A．Being changeable. | B．Being steady. |
| C．Being promising. | D．Being violent. |
| A．They are very convenient. | B．They help people kill time. |
| C．They provide a sense of community. | D．They allow people to express themselves. |
| A．The information from social media is totally reliable. |
| B．When it comes to social media, people only know short videos. |
| C．People can’t communicate with each other without social media. |
| D．There is still much room for social media to make improvement. |
| A．Objective. | B．Subjective. |
| C．Favourable. | D．Disapproving. |
7 . To help you understand what 5G is, and what it means to you, we’ve put together a handy guide here.
What is 5G?
5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands(频段) are faster, they don’t carry information as far. That’s to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity(容量).
Why is it better than 4G?
5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver 传输)peak(峰值)download speeds of around 300 Mbit/s.
Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.
| A．How does 5G work? |
| B．How will 5G affect you? |
| C．5G is also expected to have a lower lag(延迟). |
| D．5G is short for “5th generation mobile network.” |
| E．In comparison, 5G could offer download speeds of over 1 Gb/s. |
| F．Therefore, the similarity between 5G and 4G technology is huge. |
| G．This means 5G will support up to 1,000 more devices per meter than 4G. |

9 . “May 17, 2157
Dear diary,
Today, Tommy found a real book!...”
“What’s it about?” Margie asked.
“School.” replied Tommy, turning the yellow pages.
“Why would anyone write about school? I hope they can take my geography teacher away.”
“It’s not our school. This is the old sort that they had centuries ago.”
“Anyway, they had a teacher.” Margie said, reading the book over his shoulder.
“Sure, they had a teacher, but it wasn’t a regular teacher. It was a man.”
“A man? How could a man be a teacher?”
“Well, he just told the boys and girls things and gave them assignments and asked them questions.”
“A man isn’t smart enough.”
“Sure, he is. My father knows as much as my teacher.”
Margie wasn’t prepared to argue about that. She said, “I wouldn’t want a strange man in my house to teach me.”
Tommy laughed. “The teachers didn’t live in the house. They had a special building and all the kids went there.”
“And all the kids learned the same thing?”
“Sure, if they were the same age.”
“But my mother says a teacher has to be adjusted to fit the mind of each boy and girl it teaches and that each kid has to be taught differently.”
“If you don’t like it, you don’t have to read the book.”
“I didn’t say I didn’t like it,” Margie said quickly.
They weren’t even half-finished when Margie’s mother called, “Margie! School!”
“Not yet, Mamma.”
“Now!” said Mrs. Jones.
Margie said to Tommy, “Can I read the book some more with you after school?”
“Maybe,” Tommy said.
Margie went into the schoolroom, right next to her bedroom, and the mechanical teacher was on waiting for her.
The screen was lit up, and it said, “Please insert yesterday’s assignments in the proper slot.”
Margie was still thinking about the old schools they had when her grandfather’s grandfather was a little boy. All the kids from the whole neighborhood came, laughing and shouting in the schoolyard, sitting together in the schoolroom, going home together at the end of the day. They learned the same things, so they could help one another on the assignments and discussed them.
And the teachers were people…
