Spending up to five nights a week on the road can be a lonely business, leaving him with plenty of time to notice his surroundings. “I kept seeing more rubbish everywhere and it was getting on my nerves. I decided I had to do something about it,” he says. One day, he stopped his vehicle, took out a trash bag and started picking up the garbage. The satisfaction after clearing a small area was remarkable.Before his time on the road, Burrows spent over two decades in the military as a vehicle driver. His service saw him stationed throughout Europe and also on tours in Afghanistan. After returning to civilian life, he was diagnosed with PTSD (创伤后应激障碍) and had a mental health crisis in 2017. His involvement in fundraising for Help for Heroes led him to meet a man who used model-building as a distraction from PTSD．Burrows realized that his act of roadside cleanup had a similar calming effect on his mental well-being.By 2019, Burrows had begun using his free time on the road to regularly clean up garbage. A passerby encouraged him to set up a Facebook group, which he called Truckers Cleaning Up Britain. “I was worried I’d be the laughing stock of my town for putting videos and photos up of me cleaning but people started to join,” he says. “I was amazed. The local council stepped in and gave me litter-picking supplies and we’re up to almost 3,000 members now.”Since truckers are so often on the move, the Facebook page acts as a means of raising awareness rather than a platform for organizing cleanups. Burrows expressed his intention to continue the cleanup efforts as long as his physical condition allowed, as he still found joy in the process.4．What initially caused Burrows to pick up roadside garbage?A．He wanted to kill time by picking up litter.B．He aimed to raise fund for soldiers with PTSD．C．He felt annoyed to see the increasing rubbish.D．He received the assignment from his employer.5．How did collecting roadside garbage affect Burrows’ PTSD?A．It resulted in his embarrassment.B．It increased his sense of isolation.C．It worsened his stress and anxiety.D．It brought him comfort and relief. 6．What concerned Burrows when he started Truckers Cleaning Up Britain?A．He feared being teased for his action.B．He was lacking in advanced cleanup tools.C．He was unsure about the group’s development.D．He worried about the local council’s disapproval.7．What can be a suitable title for the text?A．A Joyful V olunteer Experience B．A Trucker’s Cleanup InitiativeC．A Fighting Hero against PTSD D．A Platform for EnvironmentalistsFor teenagers, is a sense of comfort more commonly found in sports or arts? And how might this relate to their reported depressive symptoms? A new research published by the American Psychological Association suggests that teenagers participating in after-school art activities like music, drama, and painting are more likely to report depressive symptoms than their non-participating peers.“This is not to say that depression is a necessary condition for either a teen or an adult to become an artist, nor are we showing that participating in the arts leads to mental illness,” said lead author Laura N. Young. MA．of Boston College. “However, previous research has revealed higher rates of mental illness symptoms in adult artists. We were interested in whether this association is present earlier in development.”Interestingly, teens who engaged exclusively in sports and didn’t involve themselves in any other extracurricular activities were reported the least depressive symptoms. The researchers found no significant difference in depressive symptoms between teens involved in the arts who also did sports and those who didn’t, suggesting that arts participation, rather than a lack of sports participation, was associated with depression.The researchers used data from the U. S. Survey of Youth collected from 2, 482 students 15 to 16 years old. The survey asked teens about their frequency of participation in arts orsports activities after school, and their experience of various moods or problems related to depression.One theory the researchers proposed for the seeming link between the arts and mental illness symptoms is that people attracted to the arts might possess certain cognitive (认知的) qualities, such as absorbing a higher level of information from their surroundings. This could lead to general unhappiness and depression, yet also enhance creativity and artistic expression. The authors suggested that personality qualities linked to depression, like introversion (内向), might guide teens towards more individual activities like the arts.“When positive behaviors such as being involved in the arts are associated with symptoms of mental illness, it’s essential that we understand why,” said Young. “Further research can address the question of whether possible psychological shortcomings can be transformed into benefits through the practice of the arts.”8．What can we learn from the research findings?A．Art activities directly lead to teen mental illness.B．Art participation can be related to teen depression.C．Sports are likely to increase depression rates in teens.D．Being depressed is necessary to become an artist later.9．Which has the closest meaning with the underlined word “exclusively” in Paragraph 3?A．only B．rarely C．regularly D．diversely 10．What is Paragraph 5 of the text mainly about?A．The overall framework of the research projectB．The direct cause of the observed phenomenon.C．The theoretical basis of the possible connection.D．The methods applied in conducting the research.11．According to Young, what should follow-up researches focus on?A．How to reduce depressive symptoms through sports.B．How to identify the positive impacts of the association.C．How to prove the link between creativity and depression.D．How to turn potential mental weaknesses into strengths.Have you noticed how the price of online purchases can increase at checkout? This is due to a strategy called “drip pricing,” coined by American economist Richard Thaler in 1971.Drip pricing is a strategy where businesses gradually add extra charges to a customer’s bill, making the initially advertised price rise.This strategy takes advantage of customers’ tendency to commit to a purchase when they see a low original price. As extra fees are added, customers often continue with the purchase despite the increased cost due to their emotional investment. Businesses, from e-commerce stores to airlines, use this technique to significantly boost their profits. The initial price of a product or service can sharply increase with the addition of various costs. For example, a flight ticket can considerably increase due to the inclusion of extra costs such as baggage fees, seating options, and access to express lanes.However, current laws seem inadequate in the face of these practices, resulting in calls for new regulations and clearer retailer responsibilities. Dr. Jane Doe from the Consumer Behavior Research Group at the University of Cambridge found that customers’ knowledge plays an effective role. “Our study shows that when customers are informed about drip pricing techniques, they are less likely to fall for them, ultimately leading to more cost-effective purchases,” Dr. Doe said.The success of drip pricing depends on customers not knowing or accepting these extra costs. An interesting suggestion to fight these practices could be the start of an annual event to highlight and criticize the worst examples of drip pricing. Possible award categories might include The Biggest Drip, Most Uselessly Named Charge, and the Droplet Award for multiple extra pricing add-ons. Such an event could strengthen customers and promote openness in pricing, thereby challenging the success of drip pricing.As we progress into the era of digital commerce, the need for transparency and fairness in pricing is becoming increasingly important. Consumer advocates argue that the key to fighting drip pricing lies not only in stricter laws and regulations from the government but also in equipping consumers with the necessary knowledge and tools.12．What does the term “drip pricing” refer to?A．An outdated approach applied in e-commerce pricing.B．An in-depth study on the continual rise of business prices.C．A pricing strategy involving added costs to the initial price.D．A cost reduction technique commonly employed in airlines.13．What drives customers to proceed with a purchase even as costs increase?A．Fear of losing previous orders.B．Restrictions from acts and lawsC．Emotional commitment to the product.D．Unawareness of the additional charges. 14．According to Dr. Jane Doe, how to protect consumers from drip pricing?A．By enforcing clear new laws B．By providing consumer education.C．By promoting cost-effective shopping.D．By organizing challenging annual events 15．What can be inferred from paragraphs 4 and 5?A．Annual events will award successful drip pricing.B．Ignoring drip pricing is an effective way to resist it.C．Consumer advocates need support from the media.D．Consumers and authorities should make joint efforts.二、七选五The rise of social media has revolutionized human connectivity, but its overuse can make people feel increasingly unhappy and isolated. 16One significant problem with frequent social media use is comparing ourselves to others. Many individuals experience “Facebook envy”. 17 Gradually, it may result in self-doubt. To boost self-confidence, it is essential to reduce time on others’profiles, and focus on self-reflection.Social media can also make it hard to form real friendships. Constant online interaction may make us feel lonely and left out when we see others having fun online. Stina Sanders, a former model, explained “When I see my friend’s photos of a party I didn’t go to, it can make me feel quite lonely and anxious”. 18Quality sleep is essential for mental health, but excessive phone use before bedtime can severely disturb it. The anxiety and envy induced by social media content can keep our brains alert, making it challenging to fall asleep. 19 Avoiding the phone for at least 40 minutes to an hour before bed can improve sleep.“ 20 However, it can also change the way we recall our life. If we direct all of our attention trying to take the perfect photo, less will be available to enjoy other aspects of the experience in real time,” said Dr. Bono. To decrease these effects, practicing self-discipline and limiting phone use can help us to stay focused and clear-minded.If you feel like social media is beginning to affect you, why not consider allocating less social media time? The slight change can do you a lot of good.A．Regular use of Facebook can keep good relationships.B．Social media offers a convenient way to record memories.C．This can lead to feelings of dissatisfaction with themselves.D．Plus, the blue light that is given off by screens affects our sleep.E．Therefore, it’s important to develop genuine offline relationships.F．Social media can lead to serious physical and mental health issues.G．The reliance on it can negatively impact people’s mental health in the long run.三、完形填空In the summer of 2015, Brian Peterson and his wife, had just moved to California.
