Have you ever turned off your alarm clock on the weekend to hope that it would pay off your weekly sleep debt (债 )? A study in Current Biology may crush those hopes, which means the catch-up sleep weekend is not helpful. The bad health effects of sleep deprivation ( 缺乏 ) on weekdays cannot be repaid by long weekend sleep.

According to a study by the University of Colorado, participants who took part in the study only slept for five hours on weekdays while sleeping as much as they wanted during a weekend. To our surprise, they got nearly three pounds over two weeks and experienced metabolic disruption (代谢混乱) that would make them become ill easily.

“If there are benefits of catch-up sleep, they’re gone when you go back to your routine. It’s very short-lived,” said Kenneth Wright, director of the sleep laboratory. “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.”

Kenneth Wright said that the study suggests sleep should come first, especially for the people spending a lot of time in watching television or on smart phones. “Even when people don’t have a choice about losing sleep because of child-care responsibilities or job schedules, they should think about sleep in the same way they think about a healthy diet or exercise.”

Michael Grandner, the sleep program director at the University of Arizona College of Medicine, said,“Imagine a person who ate nothing but cheeseburgers and French fries, Monday through Friday, but only had vegetables on weekends and tried to call that a healthy diet. That is just what people are doing when they sleep less on weekdays with the idea that they can make up for it on the weekend,” he argued.

Some other researchers found an interesting difference between men and women, in which women got less recovery sleep on the weekend, and they also were able to control their eating behavior better than men on weekends.

1.The word “crush” in Paragraph 1 probably means ________.

A.build B.break C.show D.take

2.Which of the following is TRUE according to Kenneth Wright?

A.People who sleep less would become fatter.

B.The catch-up sleep is helpful over the long term.

C.Sleep is as important as a healthy diet and exercise.

D.People who keep to their routines would be healthy.

3.What is the main purpose of this passage?

A.To give us some advice on weekday sleep.

B.To encourage us to sleep more on weekends.

C.To share researchers’ unhappy experiences of sleep.

D.To introduce some researches on weekend catch-up sleep.

When you’re not at home, many worries may start to crowd your mind. Did I turn the coffee maker off? Did I lock the door? Are the kids doing their homework or watching TV? With a smart home, you can forget all of these worries.

A smart home is a home with a communication network. This　 network　 connects(连接) devices (装置), such as lights and TV sets, and makes them to be controlled( 控制) from far away through electrical wiring( 电线), mobile phone communication or WiFi over the Internet.

More and more people may start to think about owning a smart home, because it makes life much easier. It can help keep your room at a certain temperature. It can record (录制) what happens inside the home and send the video to your phone. When you are on holiday abroad, you can use a smart home controller to switch on or off the electricity when necessary. Some smart homes can receive a visitor, allowing him to come in and offering him a drink. They can even feed the cat and water the plants.

Besides, smart homes are easy to fix. Most smart home technology and devices are wireless and can be set up with a minimum ( 最 少 量 ) of tools, using only the guiding information. When there is a problem, you can deal with it yourself without paying a professional (专业人士).

However, for home-users, the smart home technology is far from perfect. It can be rather expensive to own the technology and the devices. Also, because the smart home system ( 系 统 ) allows its owner to get home information from anywhere, it leaves the home easy to be attacked by hackers ( 黑 客 ), who may secretly use or change the information in the system.

Now, many scientists are excited about the future of smart home technology. Imagine being able to get fashion advice from your mirror, or receive food shopping suggestions from your fridge. While there are others who worry that those smart devices will make people lazier and lonelier. Whatever it is, one thing is for sure — smart home technology will change the way we live and work.

1.According to the passage, nowadays a smart home can lock the door through 　　 .

A.electric lights B.mirror technologies

C.mobile phones D.shopping programs

2.The third paragraph of the passage is mainly about 　　 .

A.Smart homes can’t help feed pets nowadays.

B.Smart homes cost a lot of money at present.

C.You can’t control your smart home in other countries.

D.It’s hard for hackers to get information from smart homes.

4.What’s the writer’s opinion(观点) according to the passage?

A.People will become less happy in the future.
