How Many Cups of Coffee per Day Are Too Many?
From cappuccinos to cold brew, coffee is a must-have to start the day for many people. 1. However, a new study suggests too much coffee can be harmful.
This is what a recent study shows. 2. A University of South Australia study led by Elian Hypponen suggests a couple of cups to start your day probably won’t hurt — and may even be good for you. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found. A cup was defined as eight ounces of coffee.
Knowing the limits of what's good for us and what's not is necessary. 3. About one in four deaths in the United States is due to heart disease, according to the U.S. Centers for Disease Control and Prevention. Heart disease is the leading cause of death worldwide. That's why Elian set out to discover how much caffeine causes high blood pressure. 4.
Elian says her findings suggest that sipping two to three cups per day is pretty safe and possibly beneficial. She also notes that if you're generally healthy, lots of evidence suggests that four cups per day shouldn't be harmful.
5. Even though the research says five cups of coffee is permissible, each person should know his or her own limit. If we begin having difficulty sleeping or feeling nervous, we might have reached our limit for the day.
A. Drink no more than six cups per day.
B. Over the limits and our health will pay for it.
C. Coffee is the most popular drink in the world.
D. But of course, don't forget to listen to our body.
E. The relation between them is quite complicated.
F. As we know, it is a key heart disease risk factor.
G. It sets you off on an energetic morning and prepares you for a busy day.
For all the technological wonders of modem medicine, health care-with its fax machines and clipboards(写字板)—is out of date. This outdated era is slowly drawing to a close as the industry catches up with the artificial-intelligence ( AI) revolution.
Eric Topol, an expert in heart disease and enthusiast for digital medicine, thinks AI will be particularly useful for such tasks as examining images, observing heart traces for abnormalities or turning doctors' words into patient records. It will be able to use masses of data to work out the best treatments, and improve workflows in hospitals. In short, AI is set to save time, lives and money.
The fear some people have is that AI will be used to deepen the assembly-line culture of modem medicine. If it gives a “ gift of time” to doctors, they argue that this bonus should be used to extend consultations, rather than simply speeding through them more efficiently.
That is a fine idea, but as health swallows an ever-bigger share of national wealth, greater efficiency is exactly what is needed, at least so far as governments and insurers are concerned. Otherwise, rich societies may fail to cope with the needs of ageing and growing populations. An extra five minutes spent chatting with a patient is costly as well as valuable. The AI revolution will also enable managerial accountants to adjust and evaluate every aspect of treatment. The autonomy of the doctor will surely be weakened, especially, perhaps, in public-health systems which are duty-bound to cut unnecessary costs.
The Hippocratic Oath(誓言) holds that there is an art to medicine as well as a science, and that “warmth, sympathy and understanding may outweigh the surgeon's knife or the chemist's drug”. There's lots of sense in it: the patients of sympathetic physicians have been shown to recover better. Yet as the supply of human carers fails to satisfy the demand for health care, the future may involve consultations on smartphones and measurements monitored by chatbots. The considerately warmed stethoscope ( 听诊器) ,placed gently on a patient's back, may become a relic of the past.
1.What's Dr Topol's attitude toward AI's coming into medicine?
A.Concerned. B.Doubtful. C.Optimistic. D.Cautious.
2.What does the author of the text attach more importance to?
A.Medical costs. B.National wealth.
C.Longer consultation. D.Greater efficiency.
3.Why is the Hippocratic Oath mentioned?
A.To prove the bright future of AI.
B.To show the advantage of a human doctor.
C.To explain medical equipment is more important.
D.To argue a human doctor performs as well as a robot.
4.What may be the best title for the text?
A.Health care and AI B.AI and its applications
C.Doctors and Patients D.Dr Topol and digital medicine
New data presented this week at the annual Associated Professional Sleep Societies (APSS) suggest that a student's preferred sleeping schedule has a lot to do with his or her grade-point average in school. In one study, researchers at the University of Pittsburg revealed that poor sleep habits among high schoolers led to lower grades, particularly in math.
It's no surprise that poor sleep habits may negatively impact academic performance. And dozens of studies have linked an increase in nightly sleep to better cognition and alertness. The new research, however, goes a step further, quantifying the impact of erratic or inadequate sleep on grades. These findings are more convincing than saying that if you get more sleep, you'll feel better," says Jennifer Cousins, a lead researcher of the study.
The study involved data from 56 adolescents (34 female) between the ages of 14 and 18 years. They were asked to fill out sleep diaries for one week and wear a special activity monitor on their wrists, which recorded when the students were asleep or awake. Overall, teens with poor sleep habits received lower grades than students who stuck with a more regular sleep routine.
Interestingly, Cousins also found that different sleep habits had different effects on the students' school performance：those who woke up more often during the night did worse in math, for example, while those who slept peacefully through the night tended to get better grades in English.
These findings bring up new questions about teasing out（探讨）the details of what is important about sleep that impacts learning," says Cousins. "Does more sleep improve our ability to deal with abstract concepts found in math, or does sleep quality increase creativity? We don't know the answers, and don't want to draw those conclusions yet. But this helps us understand more about how sleep helps the things we do in daily life. "
Authors of the study point out that the results provide overwhelming evidence of the importance of sleep during a period of development that is critical for adolescents and recommend sleep education as a prevention tool to help increase awareness of the importance of sleep and of the negative consequences of poor sleep.
1.The underlined word "erratic" in the second paragraph probably means______.
A.adequate B.different
C.stable D.irregular
2.We can learn from Jennifer Cousins' research that_____.
A.lower grades in math are related to more awakenings at night
B.the longer you sleep, the better your grades in English will be
C.the findings will cause new insoluble problems about sleeping and learning
D.different sleep habits have similar effects on students' learning
3.Which of the following do you think Jennifer Cousins will NOT agree with?
A.People should understand the importance of sleep for students.
B.Whether greater sleep quality help increase students' creativity is not known yet.
C.Students' grades mainly depend on their sleep quality.
D.The study helps researchers understand how sleep affects learning.
4.Which of the following would be the best title for the passage?
A.The More Sleep, the Better Cognition
B.The Poorer Sleep Habits, the Lower Grades
C.The More Sleep, the Better You Will Feel
D.The More Peacefully You Sleep, the Higher Grades You Will Get
