1 . Great Barrier Reef Choking on Pollutants
Attempts to protect the Great Barrier Reef are failing. A report released Monday by the government in Australia says water quality in the Great Barrier Reef is far below what it should be. It showed that pollution have decreased, but not enough to reach environmental targets.
Sediment (沉淀物) and chemicals can weaken coral, hurting its ability to feed and grow. Coral are live animals that take root in the ocean floor, but they are not plants. Reefs are the hard skeletons (骨架) left at the bottom of the sea by small marine creatures called polyps (珊瑚虫). The polyps then form the larger structure of a reef. Corals also are some of the most diverse ecosystems on the entire planet. They can make a home for invertebrates, crustaceans, fish, and sea snakes.
Steve Miles is Queensland’s environment minister. He says the research shows the Reef needs more protection. “Over that five-year period, we did see some progress towards our targets. Sediment is down 12 percent and pesticides (杀虫剂) loads are down 30 percent. But what is most disturbing is that these results are far from our targets. Progress towards these targets flat-lined in the period 2013-2014. If one of my kids came home with a report card like this, I would be a bit disappointed. There is more bad news here than good news. ” said Steve Miles.
The report also found that fewer than one-third of Queensland’s sugar plantations used techniques to reduce the use of pesticides. Only 28 percent of land managers managed their land properly. They had reduced harmful water run off to protect the health of the Reef. The official target is a 90 percent reduction in pesticide use within three years.
Scientists at the University of Queensland and the Australian Institute of Marine Sciences published their findings Wednesday, July 18 in the journal Science Advances. It found between 1992 and 2010, the recovery rate dropped by an average of 84 percent. But there is hope. The study also found some corals can recover quickly if “acute and chronic stressors” are lessened.
Meanwhile, the Australian government released its updated reef protection plan Friday. It clearly states global temperatures must be stopped from rising in order to save the world’s largest living structure.

2 . Despite the lack of new releases due to the outbreak of COVID-19, there was no shortage of good films in 2020. We've rounded out the top 4 films. Check them out!
Soul
In the first Pixar cartoon to have an African-American lead character. Jamie Foxx provides the voice of a music teacher who dreams of making it as a jazz pianist. But just after a successful interview, he falls down a manhole and finds himself in a soul world where human spirits are assigned their personalities. And things get even stranger from there.
Nomadland
When Fern loses her husband and can't afford to live in a house, she packs her few belongings into a camper and drives off into the Nevada desert. She encounters a large community of senior citizens who have also been forced to live on the road, supporting themselves with short-term- jobs along the way. What makes Nomadland unique is that while Fern is played by an Oscar-winning actress, nearly all she meets are real people who relate their own experiences. Written and directed by Chloe Zhao, the film is a combination of documentary and fiction.
The Croods: A New Age
The prehistoric family from 2013's hugely enjoyable cartoon, The Croods, directed by Joel Crawford, makes a welcome return, so we can expect more crazy adventures and unusual animals. In the much-delayed- sequel, they meet another family, the Bettermans, whose advanced lifestyle and technology make the Croods look even more primitive than they did already. There's conflict but they learn to appreciate each other's differences.
Wolfwalkers
The year's finest cartoon film comes from Cartoon Saloon, an Irish studio specialising in stylised hand-drawn 2D art. Its latest production is set in the mid-17th Century, when English soldiers are trying to occupy the wild woods. One hunter's daughter meets with a girl wolfwalker and they make joint efforts to rescue the forest. It's a heartwarming story of friendship and an inspiring adventure about two girls finding themselves Wolfwalkers stands proud as new classic.

3 . Learning a second language is difficult at any age and it only gets harder the longer you wait to open that dusty French book. Now, in a new study, scientists have pointed the exact age at which your chances of reaching fluency（流利）in a second language seem to rise： 10.
The study, published in the journal Cognition, found that it's "nearly impossible” for language learners to reach native-level fluency if they start learning a second language after 10. But that doesn't seem to be because language skills go downhill “It turns out you're still learning fast. It's just that you run out of time, because your ability to learn starts dropping at around 17 or 18 years old,“ says study co-author Joshua Hartshorne, an assistant professor of psychology at Boston College.
Kids may be better than adults at learning new languages for many reasons. Children's brains are more plastic than those of adults, meaning they're better able to adapt and respond to new information. "All learning involves the brain changing,“ Hartshorne says, “and children's brains seem to be a lot more skilled at changing. "
These findings may seem discouraging, but it was heartening for scientists to learn that the critical （关键的）period for fluent language acquisition might be longer than they previously thought. Some scientists believed that the brief window closes shortly after birth, while others stretched it only to early adolescence. Compared to those estimates, 17 or 18 when language learning ability starts to drop off——seems old.
“People progress better when they learn by immersion （沉 浸）rather than simply in a classroom. And moving to a place where your desired language is spoken is the best way to learn as an adult. If that's not an option, you can create an immersive environment by finding ways to have conversations with native speakers in their own communities," Hartshorne says. By doing so, it's possible to become conversationally fluent——even without the advantage of a child's brain.

4 . LONE TREE, colorado-patanjali Rao, a 15-year-old Colorado high school student and young scientist, who has used artificial intelligence （AI） and created apps to deal with social problems, has been named Time magazine's first-ever "Kid of the Year".
Time says Rao stood out for creating a world-wide community of young inventors and inspiring them to go after their goals. Rao insists that starting out small doesn't matter, as long as you have a passion （热爱）for it.
Rao's sense of invention started early. At age 12, she developed a portable device to discover lead in water. She has also created an app called Kindly that uses artificial intelligence to help prevent cyberbullying （网络欺凌）. It allows teens to type in a word or phrase to find out if the words they are using are bullying and lets them decide what they are sending.
She said that "Work is going to be in our generation's hands pretty soon. So if no one else is going to do it, I'm going to do it.”
Rao has partnered with schools, museums, and science, technology, engineering and math organizations, and other societies to work for thousands of other students.
In a world where science is increasingly questioned or challenged, Rao insists that devotion to science is an act of kindness and the best way that a younger generation can better the world. “We have science in everything we're involved in, and I think the biggest thing to put out there is that science is cool, innovating is cool, and anybody can be an innovator," Rao says.
"Anybody can do science.”

5 . In the 1960s and 1970s, the greatest fear was that the human race, and possibly all advanced life forms on the planet, could be wiped out by nuclear missiles. Today, however, environmental problems have taken over as the greatest risk to life on Earth. Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy. But they are also preparing for the worst: what can we do if the terrifying scenes in films such as The Day After Tomorrow happen in real life? What is our plan B for Earth?
One option is to explore other planets to see if we could live on them. The most likely choice is Mars, which is relatively close to Earth and has an environment less hostile than that of other planets. Mars has fascinated people since ancient times, and today our interest in Martian exploration is greater than ever before. Besides, more governments are making efforts to educate the public on the Red Planet.
There is no doubt that humankind is drawn towards Mars. However, sending people there will require all the skill, courage and intelligence. While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation. And even if the first settlers do reach Mars safely, they may not be able to return to Earth — ever. Staying alive will be a daily challenge, but as proved by the Biosphere 2 experiment, not impossible. As early as the 1980s, scientists were building Biosphere 2 in the Arizona desert, consisting of a closed space in which people, animals and plants could live together. Although the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet.
For now, human settlement of Mars is still decades away. Until we are finally able to live on another planet, we need to take much better care of our own. Right now, it's the only one we have!

6 . Next-generation fitness equipment and robots help you cook dinner. Those are a few of the countless new products expected to be shown next week at CES, the annual tech conference that typically sets the tone for the biggest trends of the year. Home automation, health and 5G will once again be hot topics, but many companies will also introduce pandemic-specific features to reflect our increased time at home.
Each year, reporters, exhibitors and investors typically explore Las Vegas showrooms filled with giant TVs, smart cars and robots, but CES will be online only for the first time in its 54-year history due to Covid-19.
The Consumer Technology Association, the nonprofit behind the four-day event starting Monday, said 1,800 exhibitors from around the world will fill its "digital venue" this year—a number that's down significantly from 4,000 in-person exhibitors last year. The move will allow tech companies from countries which have never attended before to take part in the online exhibition, but could also make it harder for smaller companies to get noticed without a physical showroom.
Registered attendees will be able to stream and re-watch keynotes from companies such as Verizon (VZ) and General Motors (GM), tune in to breakout sessions — about how, for example, technology is playing a role in vaccine deployment—and search through a registry of exhibitors to watch new product presentations.
It'll lack some of the signature ingredients of the trade show, such as hands-on time with the latest small machines and networking. But the technology that makes our lives more connected and convenient will still gain popularity.
1. What are the new products mainly connected with?| A．People’s daily life. | B．Everyday busy work. |
| C．The popularity of 5G. | D．Countless housework. |
| A．It takes place every two years. | B．It attracts fewer exhibitors this year. |
| C．It is held mainly on the Internet. | D．It prohibits small companies to attend. |

7 . I look around and can't recognize where I am. I see my friends gathered by a stage where music is playing and I run over. As I begin running towards them, they become further and further away. I keep calling for them, but no one hears me. I start hearing a distant alarm-like sound and I am transported away. I woke up in at a loss sitting in my bed. “Oh, it was only a dream,” I said to myself. I have always had vivid and intense dreams.
Today, dreaming is being studied even more than ever. Some say that dreams are how your receptors (受体) make sense of random thoughts while you sleep. Some say that you can't dream of a face you have never seen before, so everyone you see in your dreams you have at least laid eyes on at one time or another.
Other people think dreams are ways of expressing stress or internal feelings you may be experiencing. A lot of people say that they have dreams about being chased (追逐).
A common interpretation of the “being chased” dream is that you are feeling threatened. Some dream interpretation sites say you should try to reflect on what or who is chasing you to get a better idea of what is making you feel this way.
Another dream that is often experienced is flying. This dream has a much more positive interpretation, which is that you are feeling free or have broken out of a bad situation such as a relationship turned sour or a job you hate.
Unfortunately, if you even remember your dreams at all, you forget half of your dream within five minutes of waking up and within 10 minutes, you usually forget 90 percent of it.
Dreamologists who devote time to the study of dreams, suggest if you want to try to remember and study your dreams you should keep a journal beside your bed and jot down what you dreamt as soon as you wake up so you can reflect on it later.
1. Why does dreams of “being chased” occur?| A．You are feeling threatened |
| B．You just quit a job you hate |

8 . The River Thames has some of the highest recorded levels of microplastics for any river in the world.
Scientists have estimated that 94,000 microplastics per second flow down the river in places. The quantity is larger than that measured in other European rivers, such as the Danube and Rhine. Tiny bits of plastic have been found inside the bodies of crabs living in the Thames.
Researchers at Royal Holloway, University of London, are calling for stricter regulations on the labelling and disposal of plastic products. They warn that careless disposal of plastic gloves and masks during the coronavirus pandemic might make the problem of plastic pollution worse.
“Taken together, these studies show how many different types of plastic, from microplastics in the water through to larger items of debris physically altering the foreshore, can potentially affect a wide range of organisms in the River Thames,” said Prof Dave Morritt from Royal Holloway, “The increased use of single- use plastic items, and the inappropriate disposal of such items, including masks and gloves, along with plastic- containing cleaning products, during the current COVID-19 pandemic, may well make this problem even worse.”
Many forms of microplastics were found in the Thames, including glitter, microbeads from cosmetics and plastic debris from larger items. Most of the microplastics came from the break-down of large plastics, with food packaging thought to be a significant source. “Flushable” wet wipes were found in high abundance on the shoreline forming “wet wipe reefs”.
Study researcher, Katherine McCoy, said, “Our study shows that stricter regulations are needed for the labelling and disposal of these products. There is great range to further research the impacts of microplastics and indeed microfibres on Thames organisms.”
1. What did the researchers mainly suggest?| A．Stricter regulations should be made. | B．People shouldn't eat crabs for a while. |
| C．People should cut the use of plastic gloves | D．Plastic masks shouldn't be thrown away carelessly. |
| A．Wet wipes. | B．Food packaging. |
| C．Cleaning products. | D．Single-use plastic masks. |
| A．Wildlife Being Threatened by Microplastics. | B．Forms of Microplastics Found in the Thames. |

9 . Marco Springmann and his colleagues, at the Oxford Martin School's Future of Food Programme, built computer models that predicted what would happen if everyone became vegetarian by 2050. The results indicate that if the world went vegan, the greenhouse gas emissions declines would be around 70%.
In the US, for example, an average family of four emits more greenhouse gases because of the meal they eat than from driving two cars——but it is cars, not steaks, that regularly come up in discussions about global warming.
Food, especially livestock, also takes up a lot of room. 68% of agricultural land in the world is used for livestock. When these lands become grasslands and forests, they would capture carbon dioxide and further ease climate change.
However, if the whole world went vegan, there would be negative effects too. First, it is necessary to keep livestock for environmental purposes. "I'm sitting here in Scotland where the Highlands' environment is very man-made and based largely on grazing by sheep," says Peter Alexander, a researcher in socio-ecological systems modeling at the University of Edinburgh. "If we took all the sheep away, the environment would look different and there would be a potential negative impact on biodiversity. "
Plus, meat is an important part of history , tradition and cultural identity. Numerous groups around the world give livestock gifts at weddings, celebratory dinners such as Christmas with turkey or roast beef.
And nowadays, moderation in meal-eating's frequency and portion size is key to solving these conflicts. "Certain changes would encourage us to make healthier and more environmentally friendly dietary decisions," says Springmann, "like putting a higher price lag on meat and making fresh fruits and vegetables cheaper. "
In fact, clear solutions already exist for reducing greenhouse gas emissions from the livestock industry. What is lacking is the will to implement those changes.
1. What can we infer from the underlined sentence in the second paragraph?| A．Driving cars is more dangerous than eating steaks in the US. |
| B．Our dietary choices affecting climate change is often underestimated. |
