Traditionally, patients who want to improve their heart health have received four main suggestions from their doctors: Eat a healthy diet, get more exercise, quit smoking, and enjoy proper amounts of alcohol. Plenty of research backs up these four pieces of advice: Large studies have found that making improvements in these four areas lowers the chance of dying of heart disease by 67 percent.
But lately, researchers are starting to recognize that there should be five recommendations on that list, not just four. They’re discovering that getting enough sleep is a powerful health protector as well. When researchers include enough sleep in their studies as a fifth cardio-preventive behavior change, they find that it lowers the chance of dying of heart disease even more: Adding a good seven hours of sleep a night in addition to making positive changes in diet, exercise, smoking, and alcohol intake lowers the chance of dying of heart disease by 83 percent.
When that news started coming out, doctors began adding sleep onto their list of recommended health behavior changes. But as an expert in heart disease, I don’t think sleep belongs at the bottom of the list. I think it should be at the top. I believe that getting enough sleep – at least seven to eight hours per night for most people –is the most important health behavior change you can make to improve the health of your heart and your overall health.
Sure, I’d prefer that everyone make all of the big five lifestyle changes, but if I could only choose one, I’d pick sleep because when you are well-rested, you have more power to make the right choices about what you eat and drink, and you have more energy to exercise and kick bad habits such as smoking and overeating. But when you’re exhausted, everything in life is more difficult.
1.What does plenty of research show about the 4 common suggestions?
A. They should be reconsidered.
B. They are the best ways found so far.
C. They are not as helpful as expected.
D. They help improve people’s health.
2.What does the latest research show?
A. Various factors lead to good heart health.
B. Enough sleep contributes to good heart health.
C. Seven hours’ sleep is most important to the heart.
D. The chance of dying of heart disease has dropped.
3.How did the doctors react to the news on sleep?
A. They just ignored it.
B. They discussed it publicly.
C. They thought it made sense.
D. They totally changed their mind.
4.What does the last paragraph mainly talk about?
A. What the importance of a healthy lifestyle is.
B. Why different factors need to work together.
C. What prevents people from living healthily.
D. Why the author makes sleep his No. 1 suggestion.

ALBANY，New York—Students who rely on working at night to improve their
grades might want to sleep on that strategy: A new survey in the US says those who never study all night have slightly higher grades than those who do.
A survey of 120 students at St.Lawrence University found that students who had never pulled an allnighter on average had higher grades than those who had. The survey found those who did not study through the night had a grade point average of 3.2 compared to 2.95 for those who did.
The study, by assistant professor of psychology Pamela Thacher, is to be included in the January issue of Behavioral Sleep Medicine.
“It's not a big difference，but it's pretty striking, ” Thacher said, “I am primarily a sleep researcher and I know nobody thinks clearly at 4∶00 in the morning. You think you can do，but you can't.”
Many college students, of course, have inadequate or irregular sleep, for reasons ranging from excessive caffeine to poor time management.
“A lot of students were under the impression that allnighters were a very useful tool for accomplishing work, and that caffeine intake was very useful in meeting deadlines and stuff like that, ”said Mr Chatani, who had a 3.4 grade point average last term.
Dr Howard Weiss, a physician at St.Peter's Sleep Center in Albany, said the study results made sense.
“Certainly that data is out there showing that short sleep duration absolutely interferes with concentration and performance on objective testing, ”he said.
“Some night owls do get good grades, of course，which may be explained by circadian (昼夜节律的，生理节奏的) rhythms, ”Weiss said, “Some people have different 24hour body clocks from others, and may do better depending on classes and testing time.”
63.The purpose of the passage is to tell us
A. the bad effects of pulling an allnighter
B. pulling an allnighter leads to sleep problems
C. Thacher's doubt about allnighters
D. allnighters influence students' grades
64. According to Thacher's study，around 4 o'clock in the morning is a time when .
A. one can think more clearly
B. one has his/her best memory
C. one can't learn efficiently
D. one's brain falls into a period of deep sleep
65.What can we know from Dr Howard Weiss' words？
A. Thacher's study is not convincing enough.
B. He believes in Thacher's study.
C. Thacher's study makes no sense.
D. Thacher should take exceptions into consideration.

In a six-week study, experts found people who played online games designed to improve their cognitive(认知的) skills didn't get any smarter.
More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills for at least 10 minutes a day, three times a week. They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet and answering general knowledge questions. All participants were given a sort of I.Q test before and after the experiment.
Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.
"If you're (playing these games) because they're fun, that's absolutely fine," said Adrian Owen, the study's lead author. "But if you're expecting (these games) to improve your I.Q., our data suggests this isn't the case," he said during a press briefing on Tuesday.
One maker of brain games said the company's games have been proven to boost brain power.
"Their conclusion would be like saying, 'I cannot run a mile in under 4 minutes and therefore it is impossible to do so," Aldrich said in a statement.
"There is precious little evidence to suggest the skills used in these games transfer to the real world," said Art Kramer, who was not linked to the study and has no ties to any companies that make brain training games.
Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can spark(激发) new connections between nerves and produce new brain cells. "Fitness changes the building blocks of the brain's structure," he said.
1.. It can be inferred that the online brain games mentioned in the text are_____________.
A. costly B. unreliable C. illegal D. effective
2.. Which of the following statements is true about the experiment in the second paragraph?
A. The experiment lasted for a week.
B. Age didn’t affect the result of the research.
C. Every person played online brain games three times a day.
D. People who didn’t play online brain games did better in I.Q test
3.. What can we learn from the text?
A. Playing games which are fun can improve your I.Q.
B. There is a lot of evidence to suggest skills can transfer to the real world.
C. Do physical activity can boost your brain power.
D. Playing online games can spark new brain cells
4.The underlined sentence suggests that ___________.
A. The research was not linked to the study
B. Those playing the games can score higher in the test
C. playing the games can spark new connections between nerves
D. This isn’t the case that these games can improve your I.Q.

高三英语单项填空简单题查看答案及解析
The first patient who died on my watch was an older man with a faulty heart — the main pump had failed and his heart was beating irregularly and far too fast. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually cause more harm than good.
In a working paper, Emory University researchers found that when doctors delivering a baby have an adverse outcome, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.
Because doctors make so many decisions that have serious consequences, the fallout from second-guessing looms especially large for us. A 2006 study found that if a patient had a bleed after being prescribed warfarin, the physician was about 20% less likely to prescribe subsequent patients the blood thinner that prevents strokes. However, if a patient had a stroke and was not on warfarin, physicians were still no more likely to prescribe warfarin to their other patients.
These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.
But this phenomenon is not unique to medicine. “Overreaction to Fearsome Risks” holds true for broader society.
For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and led the state to prohibit shark feeding expeditions. Yet shark attacks had actually fallen that year and, according to the study, such a change was probably unnecessary given the extremely small risk of such an attack happening.
Humans are susceptible to emotional and often irrational thinking when processing information, adverse events and mistakes. As much as we don’t want to cause an unfortunate event to recur — in a medical setting or in the wider world — we need to be aware that a worst case scenario doesn’t necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we may inadvertently overanalyze and come to the wrong conclusion.
I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second guessing myself, I trusted my clinical instinct and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.
1.The first two paragraphs suggest that ______
A.Bad medical outcomes affect doctors.
B.Delivering babies can be difficult work.
C.Some doctors are not very experienced.
D.Doctors sometimes make silly mistakes.
2.In the blood-thinner study, doctors ______.
A.tend to prescribe less effective medicine
B.are more concerned about the patients’ safety
C.believe a stroke is more treatable than a bleeding
D.become less confident in writing certain prescriptions
3.The author develops his idea mainly by ______.
A.giving examples B.making comparisons
C.using metaphors D.quoting famous sayings
4.The author will probably agree that ______.
A.we shouldn’t doubt our own decisions
B.our experience will pave way for our future
C.humans are emotional and irrational on the whole
D.instincts don’t necessarily lead to wrong directions

Reducing class size has traditionally been seen as an important way to improve a student's educational experience.
Many public opinion studies have shown that both teachers and parents favor small class size. Teachers who go on strike are often seeking lower classroom numbers among other better working conditions. Many often believe that smaller classes would permit teachers to give more personal attention to their student. This can theoretically lead to improved academic results for student.
But one recent study suggests there is not much research-based evidence to support this idea. The researchers say the idea of smaller class sizes has been studied and debated for many years. However, they noted a lack of clear research to support class size reductions.
The study notes that one of the main problems with reducing class sizes is that it can have very high costs. Increasing class size is one of the most common ways school systems control education spending. Financial limitations make it very difficult for many schools to reduce the number of students in the classroom.
The teachers' goal was to examine the major research studies already completed on the subject. They especially centered on studies that tried to measure whether the smaller class size resulted in greater success for students.
'The researchers conclude that there is some evidence to suggest that reducing class size may lead to some improvement in a student's rending achievement. But they said "the effect is very small." They found just a 53-percent chance that a randomly selected test score from a student from a small class would be higher than the selected score of a student from a lager class. For mathematics achievement, the result was 49 percent. This led the researchers to conclude that there would be little benefit to math students in a smaller class size.
1.Why do some teachers prefer reducing class size?
A.They believe it may help improve students' academic performance.
B.It'll greatly better their working conditions.
C.They think it will bring much attention to their efforts.
D.It will offer them more time to relax.
2.What is the reason for increasing class size in many schools?
A.Making more profits.
B.Attracting more students to study.
C.Cutting down education expenses.
D.Handling the problem of a lack of teachers.
3.According to the text, reducing class size .
A.has nothing to do with students' scores
B.has a minor effect in some fields
C.has already led to greater academic success
D.isn't practical because parents object to it
4.Which of the following could be the best title for the text?
A.The Future of the Class Size Development
B.People's Preference for Class Size
C.The Cost of Reducing Class Size
D.The Little Influence of Reducing Class Size
