Teenagers are damaging their health by not getting enough sleep because they are distracted (分散) by electronic products in their bedrooms, according to a survey.

UK advice body The Sleep Council said "junk sleep" could rival (比得上) the consumption of unhealthy junk food as a major lifestyle issue for parents of teenage children. It brings no less harm than junk food to one’s health. Its survey of 1,000 teenagers aged 12 to 16 found that 30 percent managed just 4 to 7 hours sleep as opposed to（形成对照）the recommended 8 or 9 hours by the experts. Almost a quarter said they fell asleep more than once a week while watching TV, listening to music or using other electronic products.

“This is an extremely worrying situation,” said Dr Chris Idzikowski of the Edinburgh Sleep Centre. “What we are seeing is the appearance of Junk Sleep --- that is sleep which is of neither the length nor quality that it should be in order to feed the brain with the rest it needs to perform properly at school.”

Nearly all the teenagers had a phone, music system or TV in their bedroom, with around two-thirds possessing all three. Almost one in five of the teenage boys said the quality of their sleep had been impacted by leaving their TV or computer on. The survey also found that 40 percent of teenagers felt tired each day, with girls aged 15 to 16 doing the worst. However, just 11 percent said they were bothered by the lack or quality of sleep.

“I'm surprised that so few teenagers make the link between getting enough good quality sleep and how they feel during the day,” Idzikowski said. “Teenagers need to wake up to the fact to feel well, perform well and look well; they need to do something about their sleep.”

1.According to the experts, how many hours should teenagers sleep every night?

A. 4 to 7 hours B. 8 or 9 hours

C. 6 or 7 hours D. 7 or 8 hours

2.Which of the following is NOT true about “junk sleep”?

A. It’s a kind of sleep with poor quality.

B. It’s a kind of sleep with shorter hours.

C. It’s not as harmful as junk food to one’s health.

D. It’s mainly caused by the electronic products in the bedroom.

3.The underlined word “impacted” Paragraph 4 can probably be replaced by “_______.”

A. improved B. destroyed

C. affected D. provided

4.What should be the best title of this passage?

A. Junk Food and Junk Sleep

B. A Survey about Junk Sleep

C. Junk Sleep is Damaging Teenagers’ Health

D. How to avoid Junk Sleep

The exact work of ancient astronomers has led to a modern observation --- our days are longer than they used to be. Not that you’d noticed: The new research in the Proceedings of the Royal Society A shows that it takes the Earth a tiny bit longer these days to complete a single rotation (转动) than it did millions of years ago. It’s the kind of stuff that’s measured in milliseconds per century, but those milliseconds add up. Over the last thousands of years, they’d totaled several hours, which the Los Angeles Times puts this way, “If humanity had been measuring time with an atomic clock that started running back in 700 BC, today that clock would read 7 p.m. when the sun is directly overhead rather than noon. The atomic clock won’t lose a second for 15 billion years.” Maybe more remarkable is that the work is the result of a tireless 40-year research into ancient timekeeping records dating back 2,700 years.

Scientists led by Richard Stephenson of the UK’s Durham University have been studying Babylonian clay tablets, Chinese observations made through the use of water clocks, and Arab astronomical records that tracked solar and lunar eclipses(日/月食). “The most astonishing thing about this study is the fact that we have this information at all,” said a geographer not involved in the study. Researchers are still hoping to find observations from the Incas and the Maya, and to fill in their largest hole between 200 and 600 AD, but they’ve measured the Earth’s deceleration at 1.8 milliseconds per day per century. Given the moon’s gravitational effect on our oceans, the discovery that Earth is decelerating isn’t a surprise, notes the Christian Science Monitor, though astronomers had previously estimated a higher rate.

1.Why are days longer than before according to the text?

A. The earth rotates more and more slowly.

B. Humanity has got incorrect timekeeping records.

C. It takes longer for the earth to turn around the sun.

D. The lost milliseconds for centuries are added to our present days.

2.How did researchers come to the conclusion of the study?

A. By resetting the rotating time of the earth.

B. By referring to ancient timekeeping records.

C. By studying the moon’s gravitational effect on the oceans.

D. By measuring time again with an atomic clock.

3.What can we infer about the study from what the geographer said?

A. Geography theory supports the result of the study.

B. The geographer disagrees to the research conclusion.

C. The scientists’ research is meaningless.

D. It’s right to get geographers involved in the study.

4.What is the meaning of the underlined word “deceleration” in Paragraph 2?

A. Evolution. B. Slowdown.

C. Enlargement. D. Development.
