1 . A new product from Google may help people solve their sleep problems, but some privacy rights groups are concerned.

Google showed off its newest Nest Hub home assistant device on Tuesday. In addition to recognizing your voice, showing pictures, videos, news and weather, it can also track your sleep. The basic model costs about $100 and the sleep-tracking technology will be available for free for the rest of 2021. The sleep tracker makes Google’s product different from a similar home assistant from Amazon. If you put the Nest Hub beside your bed, it can follow how you sleep. That is because of a new computer chip called Soli, which can sense motion. Some people may like the new technology because they would not have to wear another device to bed. Some companies make products people can wear on their wrist to track their sleep.

Google says the new Nest Hub will create reports each week that show how long and how well a person sleeps. It will also show if they snore, cough or wake up often. The company said it studied 15,000 people over the course of 110,000 nights to develop the technology.

For people who want to know more about their sleep, the device sounds like a good idea. But, people who pay attention to privacy are worried what Google might do with the information it is gathering. Jeff Chester is one of those people. He is the director of the Center for Digital Democracy. “Google’s goal is to monetize every cell of your body,” he said.

Google recently bought FitBit, a company that makes a health tracker people can wear on their wrist. Some technology experts think Google may find a way for the Nest Hub to work with the FitBit.

Google says the sleep tracker has a lot of privacy protections. For example, it will only work if the user turns it on. The company said it will not use a person’s sleep information to try to sell advertising. But Chester said he is not so sure that promise will be kept.

2 . In previous recessions (经济衰退), billionaires were hit along with the rest of us; it took almost three years for Forbes’s 400 richest people to recover from losses caused in 2008’s Great Recession. But in the coronavirus recession of 2020, most billionaires have gotten richer than ever before.

Billionaires increased their new billions just as millions of other Americans ran into terrible financial problems. More than 20 million people lost their jobs at the start of the pandemic. Food banks across the country are preparing for another great increase in demand. Why are American billionaires doing so well while so many other Americans suffer? People may find part of the reasons from the following fact. Stocks (股票) are overwhelmingly owned by the wealthy, and the stock market has recovered from its early-pandemic depths much more quickly than other parts of the economy.

But some billionaires are also benefiting from economic and technological trends that were accelerated by the pandemic. Among these are the owners and investors of retail giants like Amazon, Walmart, Target, Dollar Tree and Dollar General, which have reported huge profits this year while many of their smaller competitors were defeated completely as the coronavirus spread.

Then there are companies that have bet on the rapid digitization of everything Eric Yuan, the chief executive of Zoom, became a billionaire in 2019. Now he is worth almost $20 billion. Dan Gilbert, the chairman of Quicken Loans, was worth less than $7 billion in March, now he commands more than $43 billion. But there is a great deal of stratification (层化) even among billionaires—richer billionaires got even richer in 2020 than the poorer ones did. Jeff Bezos, Amazon’s funder, was worth about $113 billion at the start of the pandemic. Now he is worth $182 billion. Two years ago, Bezos was the only “centibillionaire” on earth—the trendy neologism (a new word) for people whose wealth exceeds (超过) ￥100 billion.

3 . Morgan’s Wonderland, located in San Antonio, Texas, is a theme park mainly intended for mentally or physically disabled children. The park was built by Gordon Hartman, a former real estate (房地产) developer. The creation of the park was inspired by his daughter, Morgan, who suffers from severe cognitive delay and physical challenges.

The world’s first ultra-accessible family fun park, Morgan’s Wonderland opened in the spring of 2010. Admission for guests with special needs is free, and fees for the general public are set at a much discounted price so that people of all ages and abilities can come together and play in a fun and safe environment.

Completely wheelchair-accessible, the park features 25 acres of attractions including rides, playgrounds, a catch-and-release fishing lake, and picnic areas throughout the park. The rides are custom-designed to accommodate wheelchair riders so that every family member can enjoy the fun. The adapted rides include the Off-Road Adventure, where guests can test their driving skills in sporty vehicles. Moreover, each visitor is offered the option to wear a GPS Adventure Band, which allows them to keep track of each other while in the park. The band also enables them to take part in electronic activities. For example, when the riders scan the band at the Off-Road Adventure, a photo will be taken and sent to their email.

In June 2017, Morgan’s Wonderland celebrated the opening of Morgan’s Inspiration Island. The new expansion is composed of five themed splash pads and a River Boat Adventure Ride. The wheelchair guests can be moved out of their chairs into unique, waterproof chairs and enjoy the splash park without risking damage to their personal wheelchairs.

“Morgan taught me that there’s more to life in many ways than what I saw before,” said Hartman. “The blessing that Morgan has brought is beyond anything that I ever could have imagined and could explain.”

4 . In November 2020, Hurricane Eta made landfall in Central America. The storm caused huge damage from Panama to Florida. Two weeks later, Hurricane lota arrived. It was even more powerful. Heavy rain fell on places that were already flooded. President Juan Orlando Hernandez, of Honduras, said lota would leave the area in tatters.

Scientists say climate change is to blame. They don't know if it' s causing more storms, but data seems to show it's causing storms to be stronger and more harmful. James P. Kossin is a climate scientist with the National Oceanic and Atmospheric Administration(NOAA).He says the increase in greenhouse gas emissions (排放) is changing how storms behave. “These storms have a human fingerprint on them," he told TIME for Kids.

As the planet warms, so do its oceans. That' s where hurricanes begin. A storm draws its energy from ocean air. Warmer water provides more energy, which means higher winds. It also means heavier rain. Increased energy is also causing hurricanes to get stronger and faster. In August, Laura changed from a tropical storm to a strong hurricane in about a day. It hit Texas and Louisiana with winds of up to 150 miles per hour. Laura's storm surge ---- a wall of ocean water mainly caused by a strong wind --- reached 17 feet in places. It was among the highest ever recorded in Louisiana.

Hurricanes are also sticking around longer to do more damage. Rising temperatures are slowing down westerly winds, which blow around the planet. That makes storms move more slowly. In 2017, Hurricane Harvey hung around for days, flooding parts of Texas. “That storm was damaging because it didn't move.” Kossin says. “It just sat there. And it rained and rained."

Reducing greenhouse gases is the first step. Kossin says. "we can stop making it worse. Then we can try our best to adapt to the new climate we' re in."

6 . Look up in the sky. See that French poodle? Before your eyes it morphs into an elephant. A few seconds later, it becomes the profile of Taylor Swift floating by. Cloud-watching has captured our imaginations since we were children. Many people even have found the International Cloud Appreciation Society.

In 2003 Gavin Pretor-Pinney was living in Rome while on holiday. After seven months glancing into the heavens at the mostly clear blue Roman skies, he discovered he missed the constantly changing cloud formations that were an everyday event in his native United Kingdom. He returned home and was engrossed in learning about clouds. The subject dominated his conversation for a year. Then a friend invited him to speak about clouds at a small literary festival. Pretor-Pinney titled his presentation "The Inaugural Lecture of the Cloud Appreciation Society." Afterward, he had to inform audience members who wanted to join the society that it did not exist. A few months later he launched a website, and the society was born. Five years ago it became his full-time occupation.       

Today, the Cloud Appreciation Society enjoys a membership of more than 50,000 people scattered in 120 countries, all united through their appreciation of celestial mist. It is divided into local groups that include a chapter in St. Louis, and another in central Missouri. Illinois cloud spotter groups are near Chicago.

Pretor-Pinney thinks of the society as reconnecting people with their early relationship to the sky as children finding images in the clouds. "Clouds are for dreams, and a deep thinking of them benefits the soul. If you consider the shapes you see in clouds, it will save you money on psychoanalysis bills," Pretor-Pinney jokes.

In a positive Ted Talk about the Cloud Appreciation Society accessible on the Internet, Pretor-Pinney points out that clouds are common to everyone no matter where they are in the world. They are the most egalitarian (平等主义者) of nature's displays, because people all have a fantastic view of the sky.

7 . Think of Japan in the spring and the image that comes to mind is likely the country’s famous cherry blossoms, also known as “Sakura” — white and pink flowers, blooming across cities and mountains.

The flowers, which experience a “peak bloom” that only lasts a few days, have been loved in Japan for more than a thousand years. Crowds celebrate with viewing parties, flocking to the most popular locations to take photos and have picnics underneath the branches.

But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record. Scientists warn it’s a symptom of the larger climate crisis threatening ecosystems everywhere.

Yasuyuki Aono, a researcher at Osaka Prefecture University, has gathered records from Kyoto back to 812 AD from historical documents and diaries. In the central city of Kyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said. And in the capital Tokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.

The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, but have shown a general trend of moving earlier and earlier. In Kyoto, the peak date stayed around mid-April for centuries, but began moving into early April during the 1800s. The date has only dipped into late March a handful of times in recorded history.

“Sakura blooms are very temperature sensitive,” said Aono. “Flowering and full bloom could be earlier or later depending on the temperature alone,” he said. “The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius to this day.”

This year’s seasons in particular influenced the blossom dates, he added. The winter was very cold, but the spring came fast and unusually warm.

8 . Yoga originated in ancient India some 5,000 years ago. It has since spread across the world to many cultures. In the last few years, yoga has been offering classes aiming at the hearing impaired(听障者).

Most yoga classes are based on a model in which students learn by listening to their teacher's statements. As many yoga positions limit the ability to see the teacher, hearing-impaired participants who rely on lipreading (唇读) or sign language are left on their own during a class.

Recognizing the hearing -impaired are eager to attend yoga classes, one British yoga studio determined to fill the lack. Bethaney Mouzer, a yoga instructor launched Sign Yoga in 2019, with the goal of bringing yoga to people for whom the practice may have previously been forbidden.

Mouzer, who was born to non-hearing parents, is used to existing two worlds. After becoming a yoga teacher in 2015, she fielded requests from many people who were interested in yoga, but struggled to find teachers to accommodate their needs.

At first Mouzer started out small, holding single-day workshops at local studios in Birmingham and Worcester, where she signed continuously throughout the classes. The sessions were an immediate hit, and Mouzer began posting classes online via a Facebook page called Sign Yoga. Finally, once there was enough demand, Mouzer also started teaching in London.

Today, Sign Yoga is a mostly online company, with live Zoom classes and pre - recorded lessons accessible to students, as well as occasional in-person classes held in local parks. Mouzer ran a Deaf Accessible Yoga Teacher Training workshop in May.

9 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.

Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.

Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".

There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.

The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.

The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.

However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

1. What is discussed in the passage?

A．Causes of declining insect populations.

B．Consequences of insect population collapses.

C．Light pollution: the key bringer of insect declines.

D．Insect declines: the driver of the collapsed ecosystem.

10 . Arguing with your parents is totally natural for teens. From your hairstyle to your friends, to your marks at school, to your television habits, to your future plans, it might just seem like you argue with your parents about everything. While this is not generally a pleasant state of affairs, it is normal and it will most likely pass.

Argue fairly

Arguments between teens and parents generally come about when both parties believe that they know what is best for the teen. Parents have been caring for their teens for over a decade, but teens are quickly becoming adults and believe that they are able to take care of themselves. If you must agree with them, argue fairly by: Allowing each person to speak their mind. Refusing to interrupt others   when they are speaking. Sticking only to the topic at hand.

Argue respectfully

No matter how heated things may get during an argument, try to remember that your parents still are worthy of your attention, respect and love. During arguments, be respectful by: Keeping your voice lowered at all times and refusing to shout. Sitting still and staying calm. Refusing to engage in angry actions such as kicking, throwing or hitting anything. Reasonably explaining the reasons for your opinions.

________________

There is a thin line between having a discussion and engaging in an argument, but smart teens know that keeping their interactions with their parents at the discussion level practically guarantees that they will be taken more seriously. No one likes to argue, and the parents of teens can be especially weary of it, so keeping things at the discussion level will work to everyone's advantage.

Arguing with parents is practically a sign of the teenaged years, but out-of-control arguments don't serve anyone well. Before arguing with your parents, decide what type of teen you want to be and what compromises (妥协) you are willing to make in order to achieve your goals. You never know, you might just avoid an argument all together.
