2 . Social media can lead to mental exhaustion (疲惫). And when mentally exhausted, you are more likely to be influenced by a high number of likes on posts—even to the point of clicking on ads for products you don't need or want.

As a professor of advertising, I have studied social media behaviors for years. In late 2022, my colleague Eric Haley and I conducted three online studies on Americans aged 18—65 to test how people under various mental loads respond to ads differently.

The control group in each study were given no introductory task—we just had them look at an ad. A second group had to memorize a nine-digit number and then look at the ad. The third group looked through the Internet for 30 seconds and then looked at the ad. Participants randomly saw an ad with a few hundred likes or tens of thousands of likes. After viewing the ad, each participant rated how willing they would be to buy the product, and how much mental effort it took to think about the information.

The group that used the Internet first were the most likely to want to buy the featured product when there were lots of likes or comments, and they also reported using the most mental effort to assess the ad. Researchers refer to this mentally exhausted state as “cognitive (认知的) overload”. Using social media puts them in this state because they are constantly evaluating different types of texts, photos and video posts from so many different people. In the span of several seconds, they can see a text from their husband or wife, a photo from a co-worker, a video from a celebrity and an emoji from their brother. All of this evaluating leaves them feeling frazzled.

Imagine asking your roommate if they want to go get pizza. Under normal conditions, the roommate might consider several factors such as cost, hunger, timing or their schedule. Now imagine asking your roommate the same question while they are on the phone with a sick relative. They no longer have the mental energy to logically consider whether pizza for dinner is a good idea.

By understanding how social media influences them, consumers can be more thoughtful in regulating their use—and hopefully not buy yet another water bottle they don’t need.

3 . Fast food chains have tried for years to appeal to customers who care about their health. They have added lighter food to their menus, such as salads and yogurt. Of course, the lighter food goes with the usual burgers, fried chicken and shakes.

Menus have changed over the past three decades. According to a recent study, fast food menus are less healthy than they were 30 years ago. The study suggests the problem is getting worse. The fat, salt content and size of fast food meals are the problem. They are often the reason for the rising obesity (肥胖) rate among adults in the United States. The researchers found that the average main dish weighed more in 2016 than in 1986. It also had more calories and more sodium (钠). One expert said, “The restaurants have not done enough. The big picture is that there have been some positive changes, but they are small. Overall, the changes have gotten worse.”

The average fast food dessert had more calories in 2016. It also weighed more than the average fast food dessert thirty years earlier. Restaurants are counting on bigger sundaes and cookies to increase the amount spent on each order. For example, McDonald’s recently introduced “donut sticks” dusted with sugar. Six sticks have 280 calories. But you can also order 12 sticks for less than the cost of two single orders.

The researchers found that, over the 30 years, there were more calories in items like chips, soup, and French fries. Sodium content rose even though portion(一份) size did not grow much. When consumed together as a single meal, the study found that the average main dish and side order account for nearly 40 percent of a 2000-calory daily diet.

4 . New research from the University of Portsmouth has shown a marked increase in shipping in the North East Atlantic. Scientists now warn that more monitoring is required to help protect sea life.

Researchers at the University of Ponsmouth have discovered that rates (率) of shipping in the North East Atlantic area rose by 34 per cent in a five-year period. The research is the first detailed survey of shipping activity in the North East Atlantic. Researchers used data from over 530 million vessel (船) positions recorded by Automatic Identification System(AIS). They looked at the change in shipping between 2013 and 2017 across ten different vessel types. In total the study area covered 1.1 million km², including waters off Belgium, Denmark, France, Germany,Iceland, Ireland, The Netherlands, Norway, Portugal. Spain, and the UK.

Lead author, James Robbins said: “This change is likely to put more pressure on the marine (海洋的) environment, and may influence the protection of at-risk species. Renewed monitoring effort is needed to make sure that protective measures are enough to save species under threat in a changing environment.”

Some of the greatest shipping increases were found in areas close to the Spanish coast. The Espacio Marino de la Costa da Morte saw a rise of 413 percent in vessel activity. It is an area used to protect seabirds.

Dr. Sarah Marley, Visiting Researcher at the University of Portsmouth, said: “Shipping is the most widespread human activity in our oceans, carrying a set of threats-from unnoticeable effects like underwater noise pollution to serious results when ships hit whales.”

Professor Alex Ford. from the University’s Institute of Marine Sciences, said: “Given the well-documented effects that shipping can have on the marine environment, it is necessary that this situation continues to be monitored-particularly in areas used to protect vulnerable (脆弱的) species which may already be under pressure.”

1. What can we say about the new research?

A．It started in 2013.	B．It is the first of its kind.

6 . Santosh Jadhav, a 28-year-old farmer from Maharashtra’s Sangli district, had never dreamed he would be trending on YouTube tending to his land. But as you watch his videos on Indian Farmer—the channel he runs with his friend, Akash Jadhav, 27—you quickly understand why he is attracting millions of views.

Set up in 2018, Indian Farmer was a result of the two friends’ love of farming, technology and filmmaking. Their videos offer tips, advice and information on various aspects of agriculture, including direct-farming techniques, agriculture-related activities, new farming tools, and agricultural apps. In addition to explaining how agricultural markets function, the channel shares success stories from across the country. A section that draws the most attention features workable solutions to everyday problems and do-it-yourself mechanical quick-fixes.

“We were looking to do something together. Agriculture was something we had in common. Plus, we were young and idealistic—we wanted to do something with a social impact,” says Santosh.

The channel has certainly made a mark, as the numbers show. Since 2018, their channel has built a user base of 21.5 million, thanks to the affordable mobile data revolution and the increasing popularity of smartphones in India. While Akash takes charge of the production side of things, Santosh offers his hands-on knowledge obtained from running his family farm. According to them, the Indian Farmer channel adds an average of 60,000 subscribers and earns between 70,000 and 100,000 in revenue every month.

“Knowledge in this sector is often inter-generational: a farmer is limited to what the others nearby know and do. There was very little by way of books or culture channels that addressed the needs, mistakes and scarcities of farmers. Social media has changed things, enabling cross-sharing of knowledge, all for free,” Akash says.

1. What’s the channel’s most popular section?

A．Inspiring stories.	B．Advanced tools.
C．Practical solutions.	D．Agricultural activities.

C．To highlight social media engagement.	D．To indicate the success of the channel.

4. What can we learn from Akash’s words?

A．Resources were available to address farmers’ needs.

B．Farming knowledge relies on books and the Internet.

C．Agricultural modernization is dependent on technology.

D．Social media facilitates free knowledge exchange in agriculture.

7 . California has been using recycled wastewater for many years. A team has used it to make ice surfaces for the game of hockey(冰球运动). It has been used to make snow for the sport of skiing. And farmers use it to water their crops. But it has not been used directly for drinking water.

Recently, California officials approved new rules to let water agencies recycle wastewater and put it right back into the pipes that carry drinking water to homes, schools, and businesses. It is a big step for California.

California’s new rules would let—but not require—water agencies to take wastewater, treat it, and then put it right back into the drinking water system. That means proving to people that recycled water is not only safe to drink but also not dirty. California would be just the second US state to permit this, following Colorado. It has taken officials more than 10 years to develop these rules, a process that included several studies by independent groups of scientists.

A project in San Diego is aiming to produce nearly half of the city’s water through recycling wastewater by 2035. And the Metropolitan Water District of Southern California aims to produce up to nearly 570 million liters(升)a day for its 19 million people. Adel Hagekhalil is with Metropolitan Water. He said the new rules will permit new projects that have not yet been considered.

California’s new rules require the wastewater be treated for all bacteria and viruses, even if they are not present in the wastewater. In fact, the treatment is so intense that it removes all of the minerals that make fresh drinking water taste good. That means the minerals need to be added back at the end of the process. Polhemus is a director of the drinking water group for the California Water Resources Control Board. “It’s at the same drinking water quality, and probably better in many instances,” he said, adding that it takes time and money to build these treatment centers. So, they will only be available for bigger cities at first.

1. What does paragraph 1 mainly tell us about the recycled wastewater?

A．Its qualities.	B．Its functions.
C．Its target users.	D．Its disadvantages.

2. What do California and Colorado have in common?

B．They spent ten years recycling wastewater.

C．They tried to make wastewater safe to drink.

D．They requested water agencies to speed up treating water.

3. What is Polhemus’s attitude to turning recycled wastewater to drinking water?

A．Doubtful.

B．Favorable.

C．Pessimistic.

D．Indifferent.

4. What is the best title for the text?

A．The Process of Recycling Wastewater Is Complicated

B．California Tries to Reduce the Wastewater Generation

C．California Permits Turning Wastewater to Drinking Water

D．New Wastewater Treatment Projects Have Been Approved

8 . Movie stars might think their lives are private after leaving the acting location, but they ought to know that they have much power over their audience. The power gives them an ability to change people, events, even history, making them to have the responsibility of being good role models.

With time going on, movie stars become celebrities (名人) and in the process get a large number of fans. Some of them follow their deeds, dress, and act like them. In reality, they want to be like their favorite movie stars. If a movie star engages in acts that the society does not approve, those who look up to them, especially the teens, will do the same. Movie stars should be responsible for what they do and say as following the actions is now simpler because of social media. It is important to behave like a role model even when they think no one is watching.

Nobody is perfect, and movie stars also have had their down moments. They may not have been good role models at the time, but they can change the narrative by doing the right things. They can also turn the past shortcomings into positives by opening up about problems and how they overcame the challenges. And their audience can learn to discuss their problems and seek help.

People starring in movies are the target of companies to promote their products or services for a fee. Their celebrity status is a reason enough to think beyond the payment. A movie star should not recommend something that will influence the way teens live negatively. It would be wrong to promote something like sweetened drinks or foods without health benefits. Movie stars face problems like other people, but because of their influence, they have a responsibility to be role models in the public eye.

9 . While screen time is known to affect sleep, new research suggests that interactive (互动的) activities, such as texting friends or playing video games, put off and reduce the time spent asleep to a greater degree than passive (被动的) screen time like watching television, especially for teens.

The team studied the daytime screen-based activities of 475 teenagers using daily surveys. They asked the teens how many hours they had spent that day communicating with friends through social media and how many hours they spent playing video games, surfing the internet and watching television or videos. Finally, the researchers asked if they had joined in any of these activities in the hour before bed.

Next, the team measured their sleep time for one week. The researchers found that the teens spent an average of two hours per day communicating with friends via social media, about 1.3 hours playing video games, less than an hour surfing the internet and about 1.7 hours watching television or videos. For every hour throughout the day that they used screens to communicate with friends, they fell asleep about 11 minutes later averagely. For every hour to play video games, they fell asleep about 9 minutes later. Those who talked, texted or played games in the hour before bed lost the most sleep: about 30 minutes later.

Interestingly, David, lead author of the study, said the team found no obvious relations between passive screen-based activities and sleep. “It could be that passive activities are less mentally exciting than interactive activities,” said Anne, co-author of the study. “It’s a tricky situation,” she said. “These screen tools are really important to everyone nowadays, so it’s hard to put a limit on them, but if you’re really looking out for a teenager’s health and well-being, you might consider limiting the more interactive activities, especially in the hour before bed.”

10 . More than 170,000 people in California are unhoused. Even as the state has poured resources into fighting against the problem, the number of people without homes has ticked upward in recent years. On the surface, the state has one key advantage for people without a reliable roof over their heads: relatively consistent and livable weather. So one of my first thoughts when I heard news of a horricane attacking Los Angeles was just “What will happen to the city’s homeless population?”

City agencies quickly took action. As it became clear that the Los Angeles region could experience an extreme downpour and subsequent flooding, outreach teams fanned out across the river bank and dam areas across the city that have become home to a significant unhoused population, offering support to move them into shelters and motels (汽车旅馆).

Despite that, it’s obvious that the effects of climate change will hit the most vulnerable (脆弱的) hardest. We see this globally as extreme weather events hit countries that have contributed the least to the problem.

The most notable connection between climate change and the US housing crisis is the threat extreme weather poses to unhoused people. More unhoused people are affected as climate change drives increasingly unpredictable weather. People without homes know how to respond to expected seasonal events. But events like a near-hurricane in Los Angeles or a wildfire in ‘Maui can catch populations with limited access to information off guard.

Another link worth considering is the way in which climate change creates more homelessness and further stresses on housing systems. Hurricane Katrina, for example, displaced 800, 000 people. Four years later, 12,000 people remained without shelter.

Housing has been — and will continue to be — a key issue in Maui too as it recovers from the wildfire that killed more than 100 people. Maui has already had a housing crisis, the result of a high cost of living driven in large part by the tourism industry. And, now, many more are left looking for places to stay. Ashley Kelly, the chief operating officer at Hawaii’s Family Life Center, said: “Finding housing for any new clients is just not possible right now.”

3. Which word can best describe Maui’s housing circumstances now according to Ashley Kelly?

A．Mysterious.

B．Exceptional.

C．Changeable.

D．Difficult.

4. What is the text mainly about?

A．Ways of Americans relocating disaster-affected populations.

B．The significance of timely weather updates for the homeless.

C．The link between climate change and the housing crisis in the US.

D．Approaches of homeless Americans to dealing with natural disasters.
