The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and
bringing about a lot of damage. The change in how coffee is grown from shade-grown，production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world's ecological balance.
On a local level, the damage of the forest required by full-sun fields affects the area's birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees' flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate,
and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.
It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology.
But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of
the planet and mankind is surely worth more than an inexpensive cup of coffee.

    As a new driver with little experience behind the wheel, having to turn into another lane（车道）to avoid a careless driver talking on a cellphone is not something that I am prepared for. According to the New England Journal of Medicine, an accident is four times more likely to happen than normal while you are talking on the phone. Therefore, I hold the view that using a cellphone while driving should be outlawed（宣布……不合法）.

    Cars are two-ton weapons and should be treated as such. When drivers put a key in the engine, they are taking on the responsibility of being a driver. Answer the phone while driving is like taking the safety off a gun ― at any moment something could go wrong and change a life forever.

    A few countries, including Australia, Great Britain, Spain and Israel, have recognized the damage that cellphone use can cause. According to Tom Alex of The Des Moines Register, people who talk on cellphones while driving are just like drunk drivers. They are likely to make a deadly mistake, causing them to hurt themselves or someone else.

    Some may think that cellphone are helpful when you need directions or are in an emergency situation. Although I agree, I believe the safest way to use your phone is to pull over to the side of the road first. Some may think that hands-free phones are less dangerous, but studies have shown that the danger remains the same with these.

    Using a cellphone while driving should be outlawed. One small mistake could change your whole life. Please don't let that happen ― stay off your cellphone while driving.

    More and more comment(评论) sections are being shut down online.

    Autumn Phillips had had enough. On August 19, the executive editor of the Quad-City Times in Iowa, and Illinois, US visited her website, qutimes. com, and saw a story about a man who had been shot to death. When she got to the readers' comments section at the end, she was shocked by what she saw. Below the story was a growing string of comments—a racist remark about democratic( 民主的) voters, a negative comment about police...So Phillips decided to do something she had been thinking about for a long time: she shut down the comment section.

    Phillips was not alone in making such a move. Last week, NPR announced it too was closing its online comments section. The decisions don't mean that the news outlets are no longer interested in what their audiences are thinking. Both stressed their eagerness to hear from readers and listeners on social networks. But both agreed that comments had deviated from their original intention. And so they had.

    In the early days of digital journalism, comments were seen as a key part of the new media, a wonderful opportunity for strengthening the dialogue between news producers and their audiences. It was a welcome change, given that for long many news organizations were far too separated from their readers. Much more back and forth conversation seemed like healthy and welcome evolutions. Sadly, that's not the way things turned out. Rather than a place for exchanging ideas, comments sections became the home of ugly name-calling, racism and anti-women language. Besides their poisonous quality, comments seem out of place today.

    “Since we made the announcement, I've received an outpouring of responses from our readers,”she says. “I've heard from parents whose children were hurt by our online comments. I've heard from people who said they wouldn't send in letters to the editor because they were attacked so fiercely by comments, and it wasn't worth it.”

    Researchers have discovered the first Earth-sized planet. It was first marked by scientists' using NASA's Kepler telescope (望远镜), so it's called Kepler﹣186f. It lies about 500 light years from Earth and goes around its star. The planet is the right distance from its star for water: not too close or not too far. Water is one important condition that scientists guess is necessary for life. So it could have water and possible life. It's called a true Earth cousin.

    "This planet is an Earth cousin, not an Earth twin," said Barclay, who is among a team of scientists reporting on the discovery in the magazine Science this week.

    "It's very exciting to find a planet similar to the Earth," Barclay said. "It's not easy work because things change as we get more measurements."

    Scientists don't know anything about the air of Kepler-186f, but it will be a task for future telescopes which can study for chemicals that have something to do with life.

    "It's possible for life to live in this planet, but that doesn't mean there is life in it," Barclay said.

    So far, scientists have found nearly 1,800 planets in the universe.

    "The past year has seen a lot of progress in the search for Earthlike planets. Kepler﹣186f is very important because it is the first planet that is the same temperature and is almost the same size as Earth," scientist David Charbonneau wrote in an email.

    On Sunday, November 3, 2019, most North Americans will mark the end of Daylight Saving Time (DST) by moving their clocks back an hour. This simple action will not only add an extra 60 minutes to their weekend, but also shift (变换，变动) daylight back into the morning hours, making it a little less painful to wake up for school and work during the shorter winter days.

    Operating the clocks was first suggested by Benjamin Franklin in 1784. He mentioned the idea in a letter to the editor of the Journal of Paris and advised it should be a way to save candles, but it was not taken seriously. George Hudson from New Zealand also recommended moving the clocks back two hours in 1895 to get extra daylight time to study insects. Unfortunately, neither he nor British people William Willett, who suggested it in 1907 as a way to save electricity costs, got their wish.

    It was the German Empire that began the clock shifting tradition on April 30, 1916, to save fuel needed to produce weapons and bombs for World War I. Though a few others, including the US and Britain, adopted the tradition shortly after, all the countries returned to Standard Time once the war ended, only to start DST again during World War II. Once the battle ended in 1945, the US government ended DST nationally but allowed states and districts to continue the tradition and even allowed them to establish their own start and stop dates.

    However, though there have been many attempts to persuade lawmakers to end DST, both in the US and Europe, they have not been successful. Therefore, unless you live in places like Hawaii and Arizona, you have little choice but to "Fall Back" and enjoy the extra hour this weekend! Health experts suggest the best way to adjust is going to bed at your regular time, even if the day is an hour longer.

Sonya took Rupert, a rescue dog, back home three years ago, and soon found it liked attacking strangers and other animals, which she believed was caused by pain.

It took Sonya a year to develop a normal relationship with Rupert, during which she learned it was afraid of being left alone and also couldn't walk properly. Finally, she decided to take it to see a vet (兽医). After examining Rupert, the vet said its leg was broken, and it needed an immediate operation.

But when it had to go in for an operation on its leg, there was a problem—the vet Mike couldn't get near the dog. Mike and Sonya were left scratching their heads until one of them came up with an idea. Sonya said Rupert slept on a mouse suit so she suggested that Mike put it on.

At first, the dog barked wildly when Mike tried to operate on it in usual clothes. To make his patient feel at ease, Mike decided to dress up in the mouse clothes to see if it would be less worried. Amazingly, it worked. It stopped barking and immediately became good friends with Mike when he put on the suit. As a result, he was able to perform an operation on the leg safely and the result was quite satisfying.

After the successful operation, Mike hugged the dog around the neck, which isn't usually well-received by pets. Mike tried to be as respectful of its needs as possible and made time to give some attention. What Mike had done created a special experience or event in the dog's life.
