The global average temperature (平均气温) today is about 15℃. Scientists find that the planet is warming faster than ever before. The 20 warmest years on record have been in the past 22 years. If this situation continues, temperatures may rise by 3—5℃ by 2100.Scientists say we should try to stop the situation and not allow the global average temperature to rise more than 1.5℃. Even a 2℃ rise will be bad for us all. Now, 0.5℃ doesn’t sound like much—but it could make a big difference to the planet.A 2℃ rise means that all the coral reefs (珊瑚礁) will disappear, but a 1.5℃ rise means that there will still be some. Also, 18 percent of the insects (昆虫) on the earth will disappear if the temperature goes up by 2℃. But only 6 percent will disappear at 1.5℃. A 2℃ rise will also mean that 37 percent of people will be influenced by dangerous heatwaves. That’s twice the number compared to at a 1.5℃ rise.Do you want to know what scientists say? They say that everyone and everything is farbetter off in a world that limits the rise to 1.5℃.So, what can we do? Please return to us in our magazine next month, you will read about the advice given by the world’s top scientists, researchers and leading environmental protectors. We’d also like to hear about your ideas and suggestions. Please write to us at **************************.uk.Let’sworktogethertolimitthetemperatureriseto1.5℃. 43．According to the first paragraph, we can know that ________.A．the planet is the warmest this yearB．the average temperature today is 15℃ in ChinaC．the planet’s climate has the biggest change this yearD．the temperatures may rise to 18—20℃ by 210044．How can you complete the title for the passage: Climate Change: _________?A．What Can We DoB．How Does It HappenC．Why Is 1.5℃ ImportantD．How Does the Climate Change45．Which paragraphs best support the writer’s idea?A．Paragraphs 1 and 5.B．Paragraphs 4 to 5.C．Paragraphs1 to 4.D．Paragraphs 3 and 4.根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两为多余选项。

Even still, I doubt whether I could have fully prepared for this call. August 9 at 8:01 am was the first time my jaw physically dropped when manning the hotline. The harbormaster reported 30 stranded dolphins in one of the trickiest areas of Wellfleet. I immediately sent all workers we had and sent out the call for any additional help we could gather.Our team gathered at our Rescue Operations Center, grabbing all the specialized equipment we possibly could. Our trained volunteer responders arrived on the scene shortly after the initial report to give me updated information — 45 dolphins in total, 43 of which were alive. With a stranding this large, it wasn’t feasible to pull all 43 animals from the mud, get them to our mobile veterinary clinic, and transport them for release at a more favorable open-ocean location all before the tide came in. The day was getting hotter, and the animals were already suffering from both heat and sun exposure.Upon getting on the scene, there was no time to react to the sheer chaos that lay ahead. After a quick scan of the situation — 45 animals widely distributed, only a few staff members and several volunteers — there wasn’t a second more to wait. We began the hard process of getting as many animals as we could into special slings (吊带), onto the cart, and off the marsh as quickly as possible. This was not without its own challenges. The mud trapped and enveloped our feet, adding weight with each step, most animals were highly fractious (易怒的) when approached, andthe heat became unbearable in dry suits. But none of that was going to stop us from doing all we could for these animals.4．How did the author react to the call on the morning of August 9?A．He thought it was a joke.B．He was shocked to the bone.C．He didn’t take it seriously.D．He was at a loss what to do.5．What does the underlined word “feasible” in paragraph 2 mean?A．Efficient.B．Practical.C．Urgent.D．Remarkable. 6．What made a challenge to the author’s team?A．The tide was coming in very quickly.B．It was hard to find an open-ocean location.C．The volunteers failed to contact each other.D．There was deep mud around to walk through.7．What’s the text mainly about?A．A rescue effort.B．A volunteer program.C．A festive activity.D．A charity organization.This week Surgeon General Vivek H. Murthy released a warning about the risks that social media presents to the mental health of children and teenagers. Adolescent mental health has been declining for years, and an increasing amount of research suggests that social media platforms could be partially to blame. But experts continue to debate just how much impact they have.Numerous studies demonstrate that adolescent rates of depression, anxiety and loneliness have skyrocketed in the U. S. and elsewhere since around the time that smartphones and social media became ever-present.Yet the role social media plays has been widely debated. Some researchers have sounded the alarm, arguing that social media provides the most credible explanation for problems such as enhanced teen loneliness. Other researchers have been sitting on the fence. In 2019 Jeff Hancock founding director of the Social Media Lab at Stanford University, and his colleagues completed an analysis of 226 scientific papers dating back to 2006. They concluded that social media us was associated with a slight increase in depression and anxiety but also improvements in feelings of belonging and connectedness.Some recent studies have attempted to clarify the link between social media and mental health, asking, for instance, whether social media use is causing depression or whether people are being more active on social media because they’re depressed. In an attempt to present evidence, Massachusetts Institute of Technology economist Alexey Makarin and two of his colleagues conducted mental health surveys taken by college students across the country. Their study, published in 2022, found that swollen rates of depression and anxiety, as well as declined academic performance, followed Facebook’s arrival. Makarin says much of the harm they documented came from social comparisons: students viewed the online profiles of their peers and believed them to “have nicer lives, party more often, have more friends and look better.”“In total, there’s an increasingly clear picture that, indeed, social media has a negative impact on mental health,” Makarin says. “We are not saying that social media can explain 100 percent of the rise of mental health issues... But it could potentially explain a sizeable portion.”8．What do we know about social media?A．It has negative influence on adolescent mental health.B．It is the leading cause of adolescent depression.C．It plays an important role in treating mental illness.D．Its impact on mental health is still unknown.9．What is Jeff Hancock’s attitude towards social media?A．Critical.B．Objective.C．Favorable.D．Indifferent. 10．How does social media cause harm to teenagers according to Makarin?A．By threatening their academic performance.B．By presenting them with online profiles.C．By encouraging them to party more often.D．By making them feel worse-off than others.11．What is the main purpose of the text?A．To advocate the harms of social media to teenagers’ mental health.B．To analyze the causes of worsening adolescent mental health.C．To present findings on the link between social media and mental health.D．To propose an effective approach to handling mental illness.Soot (煤) pollution is speeding up climate-driven melting in Antarctica, a new study suggests, raising questions about how to protect the delicate continent from the increasing number of humans who want to visit.“It really makes us question, is our presence really needed?” says Alia Khan, one of the authors of the new study. “We have quite a large black carbon footprint in Antarctica, which is enhancing snow and ice melt.”Black carbon is the leftover thing from burning plants or fossil fuels. Soot in Antarctica comes primarily from waste gases of cruise ships (游轮), vehicles and airplanes, although some pollution travels on the wind from other parts of the globe. The dark particles (微粒) coat white snow and absorb heat from the sun the way a black T-shirt does on a warm day. The blanket of dark bits speeds up melting that was already happening more quickly because of global warming.When snow and ice are uncovered, they reflect an enormous amount of sunlight before it can turn into heat. “These are the mirrors on our planet,” says Sonia Nagorski, a scientist at the University of Alaska Southeast. “When those mirrors are covered in a film of dark bits, they don’t send back that much light and heat. That means more heat is trapped on Earth, speeding up melting and contributing to global warming.”As a scientist who personally visits Antarctica every year, Khan says she is troubled by her own research results. On the one hand, she goes to Antarctica to collect crucial data about how quickly the snow and ice there are disappearing. “But then when we come to conclusions like this it really does make us think twice about how frequently we need to visit the continent,” she says, “and what kind of regulations should be placed on tourism as well.” That could mean requiring that cruise ships and vehicles be electric, for example, or limiting the number of visitors each year. 12．What is Khan’s attitude towards human actions in Antarctica according to paragraph 2?A．Angry and abusive.B．Cold and uninterested.C．Doubtful and anxious.D．Admiring and delighted.13．What is the main cause of soot pollution in Antarctica?A．The quick melting of ice and snow.B．The emission from virous transport.C．The remaining parts of burning plants.D．The floating gases from other continents. 14．What do we know from Nagorski?A．The covered ice is less reflective.B．The melting speed of ice is slower than before.C．The dark blanket serves as a big mirror.D．The sunlight gets increasingly stronger recently.15．Which is the most suitable title for the text?A．What made our planet so polluted?B．Who is to blame for air pollution?C．Can electric vehicles save tourism?D．Are we welcome to the South Pole?Thinking about adopting a healthy lifestyle?
