The bad health effects of sleep loss during the week can’t be repaid by longer weekend sleep, according to a new study.
Researchers have long known that sleep deprivation (剥夺) can cause weight gain and increase other health risks. But for those who force themselves out of bed every weekday after too few hours of shut eye, they hope turning off the alarm on Saturday and Sunday will repay the weekly sleep debt and remove any ill effects.
The research, published in Current Biology, crushes those hopes. Despite complete freedom to sleep during a weekend recovery period, people in a sleep lab who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced disorders that would increase their risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of sleep loss, those gains were wiped out when people fell right back into their same sleep deprived schedule the next Monday.
''If there are benefits of catch-up sleep, they're gone when you go back to your daily schedule. It's very short lived'', said Kenneth Wright, director of the sleep and chronobiology lab at the University of Colorado at Boulder. ''These health effects are long term. It's kind of like smoking once was-people would smoke and wouldn't see an immediate effect on their health, but people will say now that smoking is not a healthy lifestyle choice. I think sleep is in the early stage of where smoking used to be.''
Wright said that the study suggests people should put sleep in the first place cutting out the ''sleep stealers'' such as watching television shows or spending time on their phones. Even when people don't have a choice about losing sleep because of child-care responsibilities or job schedules, they should think about getting sleep in the same way they would get a healthy diet or exercise.

Amazon is opening its 12th high-tech convenience store Tuesday in New York. The spot will be the first of the chain to allow customers to pay with cash. The move comes with growing resistance against cashless stores, which critics say refuse to serve people who don’t have bank accounts.
At other locations of the store, shoppers enter by scanning the Amazon Go app. That's still the case for customers paying with a credit card, but people paying with cash will have an “entry associate” scan them through the turnstiles (旋转栅门). Once they’re finished, those shoppers will check out with an Amazon Go employee and receive a paper receipt. Cashless customers can still walk out by scanning a phone that has the Amazon Go app at the turnstiles. Customers using the Go app can exit without waiting and get a digitized receipt.
The 1,300-square-foot New York store-the first Amazon Go store on the East Coast-will offer prepared foods, such as sandwiches and salads, It will also have Amazon Meal Kits and locally made options.
Amazon says it will begin accepting cash at its other Go stores “over time.” A number of retailers (零售商) and restaurants, such as Sweetgreen and Dos Toros Taqueria, are facing roadblocks to their cashless recommendations.
New Jersey Governor Phil Murphy recently signed a law banning cashless stores in that state. Philadelphia also passed a law to prohibit cashless stores earlier this month, and officials in New York City, Washington and San Francisco are considering similar moves. The federal government does not require retailers to accept cash.
“While card-only may be convenient for some businesses, it can actually be discriminatory against poor communities that don’t have as much access to banks or lines of credit,” said New Jersey State Senator Nellie Pou, who sponsored the state’s new law. Not accepting cash could also be bad for business. Americans use it in 30% of all business deals, according to a 2017 report from the Federal Reserve Bank of San Francisco.
1.Why is Amazon opening a new store accepting cash?
A.To persuade those critics. B.To obey the local regulations.

B.Walk out by scanning a phone with the Go app.

D.Check out with an employee and get a paper receipt.
3.How did some states and cities react to cashless stores?
A.By making laws to stop them.
B.By requiring retailers to run them.

4.What is the main idea of the last paragraph?
A.It s necessary to make cashless stores easily accessible.
B.More banks should be built in poor communities.

One-year-old Tallulah turned purple and stopped moving after the sweet became stuck in her throat. Her mum Leigh-Anne said the drama began during a visit to her grandma’s house when her grandparents gave her older kids some sweets.

I turned her round and tapped on her chest, then after what felt like forever she coughed up the sweet and spat it out.

A funny thing happened to Arthur when he was on the way to work one day. As he walked along Park Avenue near the First National Bank, he heard the sound of someone trying to start a car. He tried again and again but couldn’t get the car moving. Arthur turned and looked inside at the face of a young man who looked worried. Arthur stopped and asked, “It looks like you’ve got a problem,” Arthur said.
“I’m afraid so. I’m in a big hurry and I can’t start my car.”
“Is there something I can do to help?” Arthur asked. The young man looked at the two suitcases in the back seat and then said, “Thanks. If you’re sure it wouldn’t be too much trouble, you could help me get these suitcases into a taxi.”
“No trouble at all. I’d be glad to help.”
The young man got out and took one of the suitcases from the back seat. After placing it on the ground, he turned to get the other one. Just as Arthur picked up the first suitcase and started walking, he heard the long loud noise of an alarm.
It was from the bank. There had been a robbery (抢劫)!
Park Avenue had been quiet a moment before. Now the air was filled with the sound of the alarm and the shouts of people running from all directions. Cars stopped and the passengers joined the crowd in front of the bank. People asked each other, “What happened?” But everyone had a different answer.
Arthur, still carrying the suitcase, turned to look at the bank and walked right into the young woman in front of him.
She looked at the suitcase and then at him. Arthur was surprised. “Why is she looking at me like that?” He thought. “The suitcase! She thinks I’m the bank thief!”
Arthur looked around at the crowd of people. He became frightened, and without another thought, he started to run.
