The French Danone company is the latest to replace some plastic water bottles with aluminum (铝) cans. Competitors like Coca-Cola, PepsiCo and Nestle have also started selling water in aluminum cans.
Replacing plastic water bottles that pollute the seas with recyclable aluminum cans should be an easy way to help the environment, right?
Maybe not.
Aluminum cans might result in less ocean waste, and the metal containers also are lighter than glass or plastic bottles, but they also come with their own cost to the environment. The production of an aluminum can is estimated to release two times as much carbon dioxide into the air as a plastic bottle.
“That’s the dilemma you’re going to have to choose between,” said Ruben Griffioen, an official at beermaker Heineken. He said his company was Lrying to reduce the use of plastic bottles.
Bruce Karas of Coca - Cola North America agreed. He said, “There’s a mix. There are some things that are not that desirable, but if you have five good things and one that isn’t, we’ll all have to make decisions.” He added, “It’ll never be that clean.”
Bottled water is a 19 billion industry. Although its use of cans is increasing, experts say cans are unlikely to completely replace plastic bottles.
Aluminum is costlier than plastic so canned drinks mean higher prices for buyers. Another major consideration is user convenience-cans stay open while bottles can be reclosed. More importantly, there is one barrier to ending the use of plastic water bottles: There may not be enough cans to go around. Beer and wine makers are now also increasingly using aluminum.

Sleep, considered a luxury by many, is essential for a person’s wellbeing. Researchers have found that insufficient sleep increases a person’s risk of developing severe medical conditions. such as obesity, diabetes, and cardiovascular diseases. Now, a new study by Boston’s Massachusetts Institute of Technology ( MIT) has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Grossman, who led the research. was not trying to find the link between sleep and grades when he handed out Fitbits to the 100 students in his introduction to Solid-State Chemistry class. Instead, the professor of Computational Materials Science hoped the popular wrist-worn device which. tracks a person’s activity 24/7, would show a connection between physical exercise and academic achievement.
However, the study, published in the journal “Science Learning” on October 1, 2019, discovered a surprising insight. Then was a straight-line relationship between the average amount of sleep a student got and his/her grade on the 11 quizzes, three midterms, and the final exam administered during the semester.
Even more interesting, it was also not sufficient for students to just head to bed early the night before a test. Instead, it’s the sleep you get during the days when learning is happening that matters most.
The time students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher - performing student. “When you go to bed matters. Grossman says. If you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn’t everything.”
1.What is the new finding about sleep?
A.It's essential for a person’s health. B.Sleeping less may cause obesity.
C.Sleeping too much is dangerous. D.Ample sleep leads to better grades.
2.What does the underlined word “Fitbits” in paragraph 2 refer to?
A.Wearable devices. B.Questionnaires.
C.Fitness equipment. D.Smartphones.
3.Which of the following best describes the final result the new study?
A.Doubtful. B.Predictable.
C.Disappointing. D.Unexpected.
4.What will benefit students’ study according to Grossman?
A.Sleeping for 5 hours each day. B.Heading to bed at 3 a.m every day.
C.Getting enough sleep while learning. D.Going to bed early only before a test.
A call came into Jimmy Gilleece’s bar. A newly married woman, who had spent the afternoon at his bar, couldn’t find her wallet. She didn’t care about her ID, credit cards, or 150 in cash-but her wedding ring was inside.
Gilleece, 42, didn’t like the idea that a theft could have occurred at his place. So he determined to find the wallet. He spent hours on videos from surveillance (监控) cameras, watching the woman’s every step in the bar. Within minutes, a young man approached the bar, put something in his pocket, and walked off.
Gilleece posted a clip (视频片段) on the bar’s Facebook page to find out who the young man was. Within hours, Gilleece got a text from 17-year-old Rivers Prather, who said he’d done it because he hadn’t eaten in two days. He said he saw the ring but thought it was fake, so he took the money and threw the wallet into the ocean. Then he bought a sandwich.
Gilleece told the teen to meet him at the docks (码头). There they talked a lot and Gilleece knew that Prather was from a poor family. Seeing the teenager’s small build, Gilleece thought he was more of a kid than a criminal. However, because of the missing ring, Prather could be put into prison.
Gilleece decided to help the kid. He hired two local divers to search the waters where the wallet had been thrown. More than an hour passed, with no sign of the ring. Gilleece grew worried. And then a diver popped up. In his hand was the wallet, and inside was the ring. When Gilleece called the wallet’s owner, she burst into tears and immediately dropped the charge against Prather for stealing the ring.
1.What did the woman value most in her wallet?
A.Her ID. B.Her credit cards.
C.Her money. D.Her wedding ring.

A.He kept the ring. B.He spent the money in it.
C.He threw it in a dustbin. D.He returned it to the owner.
3.Why did Gilleece help Prather?
A.To teach the child a lesson. B.To meet the customer 's demand.

A.He would be sent to prison. B.He would not be accused by the woman.

Hi Brad,
It’s so good to write to you again, after two years. Now I have graduated in Senior High School and had been admitted into a university in Shanghai. I feel very exciting to start my new life. Therefore, I am a little nervous, for my hometown, where is in Shanxi, is far from Shanghai. What I feel homesick there? And I don’t know that whether I can get on well with my roommates. Besides, I don’t know what to adapt to the new environment quick. What should I do to get preparing for my college life?
Looking forward to your early reply!
Yours
Edith
