Here, sleep experts clear up some of the biggest misunderstandings about sleep they see with their patients, which could weaken your ability to have a night of good sleep.

Myth: 1.

The latest research shows that the right amount of sleep may vary from person to person and should leave you feeling energized the next day. I’m a sleep doctor. Take myself for example. 2. .

Myth: Don’t fall asleep with the TV on.

I’ve cured more people suffering from sleep problems than you can imagine by telling people it’s OK to fall asleep with the TV on. 3. Control the watching time so it doesn’t affect your sleep later in the night.

Myth: You can catch up on lost sleep on the weekend.

4. A Harvard study found that even if you sleep for an extra 10 hours on the weekend to make up for only sleeping six hours a night for two weeks, those extra hours won’t improve your reaction times or ability to focus. Plus, sleeping late throws off your biological clock, which can lead to obesity, diabetes, and heart disease.

Myth: Alcohol can help you rest easy.

5. Alcohol may relax you so you nod off quicker, but studies show you’ll wake up more and get less of deep sleep you need to feel rested.

A. You need 8 hours’ sleep a night.

B. A lack of sleep can cause anxiety.

C. We take unscheduled naps during the weekend.

D. I’ve been a 6.5-hour sleeper my entire adult life.

E. Many people can’t turn off their brains, but watching TV helps.

F. People commonly use alcohol to fall asleep, but it doesn’t work.

G. You can’t make up for too little sleep by sleeping more at weekends.[来

A young man named Ted received a high-priced car from his brother as a Christmas present. On Christmas Eve when Ted came out of his office, a street urchin (顽童) was walking around the shining car. “Is this your car, Ted?” he asked.

Ted answered, “Yes, my brother gave it for Christmas.” The boy was surprised. “You mean your brother gave it to you and it cost you nothing? Boy, I wish…” He hesitated(犹豫).

Of course Ted knew what he was going to wish for. He wished he had a brother like that. But what the boy said surprised Ted greatly.

“I wish,” the boy went on, “that I could be a brother like that.” Ted looked at the boy in surprise, and then said, “Would you like to take a ride in my car?” “Oh yes, I’d love that.”

After a short ride, the boy turned and with his eyes shining, said, “Ted, would you mind driving in front of my house?”

Ted smiled a little. He thought he knew what the boy wanted. He wanted to show his neighbours that he could ride home in a big car. But Ted was wrong again. “Will you stop where those two steps are?” the boy asked.

He ran up to the steps. Then in a short while Ted heard him coming back, but he was not coming fast. He was carrying his little crippled (残疾) brother. He sat him down on the step and pointed to the car.

“There she is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn’t cost him a cent. And some day I’m going to give you one just like it… Then you can see for yourself all the nice things in the Christmas window that I’ve been trying to tell you about.”

SAN FRANCISCO—Only 21 percent of workers worldwide are “engaged”—that's the word used to describe workers who are ready to expend some extra effort at work—while 38 percent are disengaged, according to a new survey.

“Engagement is not satisfaction or happiness, but the degree to which workers connect to the company emotionally, and the degree to which workers are aware of what they need to do to add value and are willing to take that action," said Julie Gebauer, a managing director of Towers Perrin, a consulting firm, which surveyed almost 90,000 workers in 19 countries.

“Happy employees don't necessarily create better financial results, but there is a definite link between engagement and a company's financial performance,” Gebauer said.

The survey found 21 percent of workers worldwide are engaged, and another 41 percent are “enrolled”, which means they're on the road to engagement.

More than 80 percent of the engaged employees say they contribute to the quality of company products, services and customer satisfaction, while only 40 percent of disengaged workers agree.

Engagement helps retention(留置) too. About 50 percent of engaged employees say they have no plans to leave their company versus 15 percent of the disengaged.

“The fact that almost 80 percent of workers are disengaged is likely costing companies money." Gebauer said.

“The conception of engagement is really a financial issue," said Gebauer. ‘Organizations that have employees that are highly engaged deliver better financial results than those that don't."

In a separate study, Towers Perrin assessed data on 40 global companies over a three-year period, measuring employee engagement at a certain point and then looking at the companies' financial results over the following three years.

Companies with highly motivated workers enjoyed a 3.7 percent increase in profits, while companies with a lower level of worker commitment saw a decrease in profits slightly.

What makes for an engaged employee? It's not necessarily pay. While the level of pay is important, it's not among the top 10 drivers of engagement. Rather than only using the pay, companies should survey their work force, much as they might study their customers, to assess what employees are seeking.

1.The underlined word “enrolled” in Paragraph 4 means ________.

A. engagedB. disengaged

C. over-engagedD. not yet but to be engaged

2.According to the text, among 500 disengaged employees, how many would probably have the intention of leaving their company?

A. 50.B. 75.C. 250.D. 425.

3.What would probably be talked about following the last paragraph?

A. The top ten drivers of engagement.

B. The reason to encourage engagement.

C. The importance of the pay level in engagement.

D. The survey of work force in a company.

For years, scientists and others concerned about climate change have been talking about the need for carbon capture and storage (CCS).

That is the term for removing carbon dioxide(二氧化碳) from, say, a coal-burning power plant’s smokestack and pumping it deep underground to keep it out of the atmosphere, where it would otherwise contribute to global warming.

However, currently, only one power plant in Canada captures and stores carbon on a commercial scale (and it has been having problems). Among the concerns about storage is that carbon dioxide in gaseous or liquid form that is pumped underground might escape back to the atmosphere. So storage sites would have to be monitored, potentially for decades or centuries.

But scientists at Lamont-Doherty Earth Observatory at Columbia University and other institutions have come up with a different way to store CO2 that might eliminate that problem. Their approach involves dissolving the gas with water and pumping the resulting mixture — soda water, essentially — down into certain kinds of rocks, where the CO2 reacts with the rock to form a mineral called calcite(方解石). By turning the gas into stone, scientists can lock it away permanently. Volcanic rocks called basalts(玄武岩) are excellent for this process, because they are rich in calcium, magnesium and iron, which react with CO2.

The project called CarbFix started in Iceland, 2012, when the scientists pumped about 250 tons of carbon dioxide, mixed with water, about 1,500 feet down into porous basalt. Early signs were encouraging: The scientists found that about 95 percent of the carbon dioxide was changed into calcite. And even more importantly, they wrote, the change happened relatively quickly — in less than two years.

“It’s beyond all our expectations,” said Edda Aradottir, who manages the project. Rapid change of the CO2 means that a project would probably have to be monitored for a far shorter time than a more conventional storage site.

There are still concerns about whether the technology will prove useful in the fight against global warming. For one thing, it would have to be scaled up enormously. For another, a lot of water is needed — 25 tons of it for every ton of CO2 — along with the right kind of rock.

But the researchers say that there is enough porous basaltic rock in Iceland, including in the ocean floors and along the margins of continents. And sitting a storage project in or near the ocean could potentially solve the water problem at the same time, as the researchers say seawater would work just fine.

1.What can we learn about CCS in Paragraphs 2 and 3?

A. Scientists believe global warming will be avoided if CO2 is pumped underground.

B. It’s been a common practice in many plants to capture and store CO2 underground.

C. There is no guarantee that CO2 will not escape even if pumped underground.

A. Water, CO2, soda water and basalts.

B. Water, CO2, a pump and basalts.

C. CO2, basalts, a pump and calcite.

D. Water, soda water, a pump and calcite.

3.According to Edda Aradottir, the result of the project was beyond the researchers’ expectations, because ________.

A. it’s disappointing to discover new problems caused by rapid change

B. it’s exciting to sense the problem of storing CO2 likely to be solved

C. it’s puzzling to find the encouraging but unexpected result of the project

D. it’s amazing to see 95% of the carbon dioxide turn into calcite that fast

4.What is the author’s purpose in writing the passage?

A. To show the different ways to fight against CO2.

B. To praise the efforts of scientists in storing CO2.

C. To inform us of a breakthrough in storing CO2.

D. To urge people to produce the least possible CO2.
