Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.

Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

1.The text mainly discusses the relationship between ______ .

A. heart problems and air quality               B. heart problems and exercising

C. heart problems and smoking         D. heart problems and fatty food

2.The underlined word “modest” in Paragraph 3 most probably means ______ .

A. relatively high                                          B. extremely low

C. relatively low                                               D. extremely high

3. What can we learn from the text?

A. Eating fatty food has immediate effects on your heart.

B. The EPA conducted many studies on air quality.

C. Moderate air quality is more harmful than smoking.

D. Stricter regulations on pollutants should be made.

4.The author’s purpose of writing the text is most likely to _______.

A. inform          B. persuade          C. describe              D. entertain

If our bodies actually suffer from eating too much sugar, then why do we like it? And why don 't we have such a strong eager for food like, say, broccoli (西兰花)，which is a great source of Vitamin C,Vitamin K iron, all things our body actually needs? If it's so bad for us, then why does sugar taste so good? There are hundreds of journal articles trying to answer that very question. Let' s take a look at what they' ve come up with.

Studies have shown that the love children have for sugar may be born with. In other words, kids may have a built-in love of all things sweet. The preference for sweet foods is found to be already evident in newborns, who prefer sweeter formulas (配方). It also seems to be shared by children globally across cultures and climates. There’s further evidence that kids’ taste buds (味蕾) are more sensitive to bitter-tasting foods, further pushing them to reach for the sweets. One study showed that adults tend to maximize their sugar preference at about the level of sugar in a can of soda, but older children still liked drinks that were twice as sweet. The scientists couldn't find a limit to the concentration of sugar younger children preferred. It turms out that the kids still liked the sugary drink even past the point where there was too much sugar to be dissolved (溶解) in water anymore.

Sugar gets a bad fame, but it isn't all bad. Sugar provides our bodies with calories, which we can then change into energy. Children, in particular, need this energy to fuel their rapid growth. Sugar also helps us store fat, which can be drawn on later if needed. Our body knows to pursue the things it needs as two way of signaling our brain to start eating what we’re missing.

As a vegetarian (素食主义者)，I know that when I start thinking about stealing the peanut butter sandwich that's been floating around in my kid' s backpack, it' s probably not because the sandwich is so delicious. It' s more likely that I haven't gotten enough protein for the day.

1.What makes so many people study sugar?

A.High sugar intake.

B.Curiosity about Sugar.

C.The love for sugar.

D.The magic effect of sugar.

2.What do the studies show about eating the sweets?

A.Loving sugar is human's nature.

B.A vegetarian doesn't like sugar so much.

C.The older one is, the more sugar one needs.

D.The love for sugar depends on living habits.

3.How does sugar impress us according to the text?

A.Deadly but irresistible.

B.Beneficial but harmful.

C.Necessary but not welcome.

D.Useful but not nutritious.

4.Why does the author steal his kid's food?

A.To store more protein,

B.To treat his illness.

C.To avoid his kid eating more.

D.To meet body' s needs.

High-sugar diets raise risks for heart disease, obesity and diabetes, but we do love our sweets, so health experts have tried to suggest alternatives, and honey has been foremost among them.

Honey is actually sweeter than sugar is , which means, in theory at least, that you could enhance flavor equally with a smaller quantity of honey. But honey actually has a higher calorie count. It may have more minerals, which looks better on a label but, in reality, these are such trace amounts that they don’t offer any real advantages.

Honey’s reputation as a medicine is not wholly unfounded. Some honey does indeed have antibacterial properties. One byproduct of enzymes in honey is hydrogen peroxide, a powerful germ killer. Plus, honey’s texture and consistency are good for keeping wounds clean, and bad for bugs that might want to infect them. Honey is moist and its gooey consistency mean it can easily spread over and stay over wounds while keeping the tissue from becoming dry and fragile. The sticky substance means bacteria can not accumulate and multiply easily. It is particularly well-known for fighting bacteria like staph, salmonella, E. Coliand certain bacteria that can infect the gut and cause ulcers.

However, scientists can only say this for sure about Makuna and Malaysian Tualang honey. We don’t know yet whether local home grown honey has the same potency-or safety. A hot cup of tea with some honey stirred in certainly sounds like it would make you feel better. But it’s difficult to say for sure that it will.

When you have a cold, contact with warm water (from tea) may help to bust up phlegm(痰）that blocks your airways. But some suspect the real secret to the qualities of a cuppa is in the honey. There are studies that suggest that honey does work as well or better than cough suppressant（抑制性的）drugs like Robitussin.

Most of these, however, were considered by the academic world to be widely misinterpreted by the media. One of the findings that seemed to have given the honey trend some additional legs came from a study that said there was “no difference”, statistically speaking, between honey and one particular cough suppressant.

1.What can we learn from the passage?

A. Honey has more minerals than sugar.

B. Honey can be used to treat wounds.

C. The sweetness in honey can fight bacteria.

D. All kinds of honey can act as medicines.

2.What is the author's attitude when it comes to the functions of honey?

A. Objective　　 B. Critical

C. Supportive　　 D. Skeptical

3.What might be talked about next?

A. Honey will be widely used in other fields.

B. Honey will not be recommended in medical treatment any more.

C. Other studies showed honey worked better than some cough medicines.

D. Other studies showed neither honey nor some cough medicines functioned well.

It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.

In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those“fortunate”few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dying compared to the seven-hour crowd.

The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation（适度）.

You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology.　 Researchers discovered that even if a person sleeps more　 than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight　 and developing sensitivity to insulin, which controls the level of sugar in blood.

For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine　 hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on　 weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived（睡眠不足的) groups consume more food and gain weight.

1.Why is the harmful effect of sleeping too much seldom studied?

A.Few people have time to sleep too much. B.Lack of sleep causes much more harm.

C.It turns out to be a healthy sleep pattern. D.People's health has nothing to do with it.

2.What does the underlined words "those 'fortunate' few" in paragraph 2 refer to?

A.Those leading a relaxing life. B.Those getting too much sleep.

C.Those with less time to sleep. D.Those with no sleep problems.

3.What can be learned from the 2019 study?

A.Sleeping much is particularly beneficial to hungry people.

B.Many people sleep more on weekends than on weekdays.

C.An alarm clock of high quality is important for good sleep.

D.People who sleep much only on weekends also have health risk.

4.What is the main idea of the text?

A.It is necessary to save enough time for sleep.
