Brad Hassig was doing underwater exercise at his home swimming pool, something he said he’d done numerous times before. “We were just swimming. The boys were having fun. I like to do just some calming, breathing exercises in the waters, which involves just sitting underwater,” Hassig said. “I don’t ever remember finishing it.”Hassig’s 10-year old twin sons Bridon and Christian, as well as an 11 year old neighbor named Sam, were in the pool with him, enjoying the water, when they noticed something was wrong with their dad, who had turned a blue color. They quickly jumped into action, dragging their 185-pound father above water and toward the side of the pool.“They weigh 80 pounds around, and I weigh 185 pounds. So they should’ t have been able to physically do what they did,” Hassig said. “I mean everything just went as perfectly as it probably had to have.”Although the boys had no formal CPR (心肺复苏术) training, they remembered what they had seen in the movies. They started chest compressions and mouth-to-mouth and Christian and Sam also ran for help after the boys couldn’t unlock their dad’s phone.When Hassig came to life, he said he heard his sons calling out to him. “I hear the boys saying, you know, ‘Daddy, come back!’ ‘Daddy, you have to be OK!’ ” he recalled.Hassig and his sons’ experience calls to mind another recent close call when synchronized swimmer Anita Alvarez lost consciousness during competition and had to be pulled to the surface by her coach, Andrea Fuentes.Since the incident, Hassig has told others to never swim alone and the family urges people to learn how to do CPR. They’re planning a local, community-wide CPR event for kids and adults to get proper training.4.What were the boys doing when their dad got into trouble?A.They were swimming for fun.B.They were calling their neighbour.C.They were making preparations for swimming.D.They were cleaning the home swimming pool.5.What difficulty did the boys have when saving their father?A.They couldn’t pull their father.B.They couldn’t use their father’s phone.C.They didn’t know how to perform CPR.D.They were too frightened to run for help.6.What does Hassig advise people to do after the incident?A.Do underwater exercise before swimming.B.Make sure to swim with companions for safety.C.Never swim alone before getting the formal training.D.Turn to a swimming coach when meeting a similar situation.7.Which of the following can best describe the boys?A.Professional and kind.B.Cooperative and generous. C.Enthusiastic and smart.D.Courageous and calm.Thousands of emperor penguins pack together on the ice of Atka Bay in Antarctica, mostly unaware that among them lives a 3-foot-tall autonomous robot called ECHO. The birds occasionally notice the unmanned and remote controlled ground vehicle out of curiosity but quickly move on from the object, which acts like a mobile antenna(天线)for an observatory monitoring about 300 of them each year.Penguins dominate the South Pole, but the climate crisis could threaten their very existence. A study published last year reported 98% of the emperor penguin population could all but disappear by 2100 due to the impact of climate crisis in Antarctica. “As top predators, emperor penguins serve as ideal species to study in an unsteady ecosystem,” said Zitterbart, associate scientist at the Woods Hole Oceanographic Institution.Surprisingly little is known about these penguins because Antarctica isn’t the easiest place for scientists to access. Although it’s crucial to learn more about the penguins and their ecosystem, Zitterbart and his team didn’t want to introduce a harmful human footprint in an already vulnerable environment or negatively affect the colony.A successful trial run of ECHO this year is already showing how that may be possible.Since 2017, Zitterbart and other researchers have been tagging 300 penguin chicks with a system similar to how dogs and cats are microchipped. But the small sensors worn by the penguins don’t have their own power supply, so they can only be read from about a meter or two away.That’s where ECHO comes in. The robot acts like a receiving station with wireless receivers, automatically collecting data from the penguins’ sensors. With ECHO, the researchers don’t miss out on a chance to collect data when the birds return to the colony to feed their chicks and no longer have to search through a crowd of 20,000 birds to find the tagged ones because ECHO picks up on them automatically.Tracking the penguins allows the team to determine where the penguins go when they dive off the sea ice into the ocean and understand their food hunting strategies. “In the next stage, we will extend ECHO’s data collection to include penguins’ reproductive behaviors that scientists haven’t been able to collect before,” said Zitterbart.8.What’s emperor penguins’ reaction to ECHO?A.Defensive B.Frightened.C.Undisturbed.D.Unfriendly. 9.What does “that” in paragraph 4 refer to?A.Cutting carbon dioxide emission in Antarctica.B.Studying penguins without polluting the land.C.Having access to more knowledge about Antarctica.D.Involving more scientists in studying emperor penguins.10.What is the team likely to study about emperor penguins in the future?A.How they produce young.B.Where they search for food.C.When they dive into the deep sea.D.Why they can survive the extreme cold.11.What can be the best title for the text?A.Emperor penguins are dying out.B.Uncover more mystery of penguins.C.Technology brings life back to Antarctica.D.Meet the robot in the Antarctic penguin colony.Interest in sleep tourism is increasing, with a number of establishments focusing their attention on those suffering from sleep deprivation.Over the past 12 months, Park Hyatt New York has opened the Bryte Restorative Sleep Suite, a 900-square-foot suite filled with sleep-enhancing amenities(设施),while Rosewood Hotels &. Resorts recently launched a collection of retreats called the Alchemy of Sleep, which are designed to “promote rest”, and Swedish manufacturer Hastens established the world’s first Hastens Sleep Spa Hotel, a 15-room boutique hotel a year later.Dr Rebecca Robbins, a sleep researcher and co-author of the book Sleep for Success! believes this shift has been a long time coming, particularly with regards to hotels. “When it comes down to it, travelers book hotels for a place to sleep,” she says, before pointing out that the hotel industry has primarily been focused on things that actually detract from sleep in the past. “People often associate travel with luxury meals, postponing their bed times, the attractions and the things you do while you’re traveling, really almost at the cost of sleep,” she adds.According to Dr Robbins, travel experiences centered around “healthy sleep strategies” that aim to supply guests with the tools they need to improve their sleep can be hugely beneficial, provided a reputable medical or scientific expert is involved in some way to help to deter- mine whether there may be something else at play.Mandarin Oriental in Geneva has taken things a step further by teaming up with CENAS, a private medical sleeping clinic in Switzerland, to curate a three-day program that studies guests’ sleeping patterns in order to identify potential sleeping disorders.As sleep tourism continues to grow, Dr Robbins says she’s looking forward to seeing “who really continues to pioneer and think creatively about this space”, stressing that thereare countless means that haven’t been fully explored yet when it comes to travel and the science of sleep.12.What is the main purpose of paragraph 2?A.To list the consequences of sleep deprivation.B.To prove the popularity of some hotels.C.To highlight the importance of quality sleep.D.To provide evidence for the rise of sleep tourism.13.What does the underlined phrase “detract from” in paragraph 3 probably mean? A.Benefit.B.Influence.C.Measure.D.Analyze. 14.What is special about Mandarin Oriental in Geneva?A.It sets up a private medical sleeping clinic in its hotel.B.It suggests some good and scientific sleeping bedding.C.It provides special tour route for people with sleeping disorders.D.It offers professionally medical help in sleeping problems.15.What does Dr Robbins probably think of the sleep tourism?A.It’s promising.B.It meets some doubts.C.It is facing bottleneck.D.It needs to be systematized.二、七选五Becoming more optimistic can help you see people, situations and tasks with a more positive outlook. ___16___However, optimism is actually an ability that individuals can choose to develop. Here are some steps to become more optimistic.Keep a gratitude journal. Write every day in a gratitude journal. A gratitude journal is a place where you regularly write things you feel grateful for.
