1 . In high school, it’s important to stay healthy.     1     How can you study well if you’re sick? So you should pay attention to your health in order to study well in high school. In order to enjoy good health, you should have some good habits. Here are some tips for you.

Drink water regularly every day. Some students don’t like drinking water. They only drink water when they are extremely thirsty.     2     You should drink water regularly so that your body and brain can work well. Avoid sports drinks and soda when you are thirsty. They are not good for your health.

Don’t skip (跳过) meals. Some students don’t eat three meals a day. No matter what happens, you should not skip any meal of the day. Eating regularly helps keep your metabolism high and keep your energy up. It’s especially important to eat a good breakfast every day with protein, carbohydrates, and fiber to set up your body for the day of activity.     3    

Eat the right foods. Some students eat whatever they can get. This is wrong.     4     Choose whole grains like rice and whole wheat flour, protein, fruits and vegetables. Skip muffins, donuts, and other processed foods.

    5     If you do that, you can get distracted. Therefore, you may not pay attention to how much you are eating. You may eat too much.Eating too much harms your health. And you may gain too much weight because of it. Try to eat slowly so your brain sends the right signals to tell your stomach that it’s full.

A．Eat a good breakfast every day.

B．If you don’t eat, how can you stay focused in class?

C．This is bad for your health.

D．If you are unhealthy, you may fall ill easily.

E．You should eat the foods that are good for your body.

F．Avoid eating too much at one time.

G．Don’t watch TV or movies when you eat.

2 . It’s hard to turn down hamburgers, french fries, potato chips and all of the other junk food that seem to call out to us. However, eating too much junk food can harm your body, particularly if you’re a teenager.

“Junk food shapes teenager’s brains in ways that damage their ability to think, learn and remember. It can also make it harder to control bad behaviors,” said Amy Reichelt, a brain and nutrition specialist at Western University, Canada. “It may even up a teen’s possibility of depression and anxiety.”

Reichelt and two other researchers reviewed more than 100 studies, including their own,about how poor food choices can impact teen’s brains.They found teens are more sensitive (敏感的) than any other age group to processed foods with a lot of fat and sugar as their brains are not yet fully formed.

Teenagers’ brains are still developing the ability to assess bad possibilities and control actions. The prefrontal cortex is the part of the brain that tells us we shouldn’t eat chips all the time and helps us resist ( 抵 制 ) that urge. However, this region is the last to mature (成熟) — it doesn’t fully develop until we are in our early 20s.

So, what’s the best way to say no to junk food? Researchers suggest exercise. When we exercise, the brain’s reward system becomes less sensitive to food reminder. Exercise also causes the body to make a protein that helps brain cells grow and strengthens connections between the prefrontal cortex and other brain regions. The prefrontal cortex thus can work better to help us make wise decisions and control our impulses.

D．The prefrontal cortex develops fully in our late 20s.

4. What’s the main idea of the last paragraph?

A．Where do our impulses come from?

B．Why should we fight against junk food?

C．What is the best way to strengthen our body?

D．How does exercise work against junk food?

3 . On the day he almost died, Kimbal Musk had food on the brain. The Internet startup talent and restauranteur had just arrived in Jackson Hole from a conference where chef Jamie Oliver had spoken about the benefits of healthy eating. This was something Musk thought about a lot — how he might make a difference to the food industry — but beyond expanding his farm-to-table movement along with his restaurant, Musk hadn’t yet broken the code. Then he went sailing down a snowy slope and fell over, breaking his neck. The left side of his body was paralyzed.

Musk eventually made a full recovery, but it involved spending two months on his back, which gave him plenty of time to come up with a plan. Since then, he has launched an initiative to put “learning gardens” in public schools across America; attracted Generation Z to the farming profession by changing shipping containers into high-tech, data-driven, year-round farms; and this year, is kicking off a new campaign to create one million at-home gardens.

Aimed at reaching low-income families, the Million Gardens Movement was inspired by the pandemic, as both a desire to feel more connected to nature and food insecurity have been at the forefront of so many people’s lives. “We were getting a lot of inquiries about gardening from people that had never gardened before,” says Musk. “People were looking to garden for a bunch of reasons: to supplement their budget, to improve the nutritional quality of their diets, or just to cure the boredom that came with the lockdown.”

The program offers free garden kits that can be grown indoors or outdoors, and will be distributed through schools that Musk’s non-profit, Big Green, has already partnered with. It also offers free courses on how to get the garden growing and fresh seeds and materials for the changing growing seasons. “I grew up in the projects when I was young, in what we now call food deserts,” says EVE, one of the many celebrities who have teamed up with the organization to encourage people to pick up a free garden. “What I love about this is that it's not difficult. We are all able to grow something.”

1. What does the underlined expression “broken the code” in paragraph 1 probably mean?

A．broken the rule.	B．found a way out.
C．spared no effort.	D．made up his mind.

2. What can we learn about the Million Gardens Movement?

A．It has just accomplished its target.

B．It has mainly attracted young generations.

C．It increases economic burdens for the poor.

D．It is partly due to the lack of food security.

3. Which of the following best describes Musk?

A．Serious.

B．Flexible.

C．Charitable.

D．Straightforward.

4. Why is EVE taken as an example?

A．To share his experience in a food desert.

B．To encourage people to start a free garden.

C．To clarify the reason why he loves a garden.

D．To demonstrate the program to be non-profit.

5 . Comfort food makes a person feel good. Food high in sugar or fat tends to improve mood by stimulating the brain’s reward system. So it makes sense that many of us may turn to food for comfort in times of stress. There’s some fascinating research that examines food as a source of comfort. However, the most interesting thing about this research may be that foods are far less comforting than we tend to believe they are.

Traci Mann, a professor of psychology, and colleagues conducted a series of study with college students. The researchers examined how much comfort foods actually improve mood. They provided students with one of the three foods that they had indicated were their top, personal comfort foods. After producing a negative mood by having them watch movie clips designed to increase their sadness, anger and anxiety, the researchers offered the students their comfort food.

They had to assess (评估) how they felt before and after they were supposedly comforted by ice cream, pizza or whatever they had indicated they typically ate to feel better. All of the students completed the study on two separate occasions: once when they were able to eat their comfort food and once when they were able to eat another food they liked, but they wouldn’t call a comfort food. The researchers found that comfort food did improve students’ moods — but only by a little bit and not more than the other food they liked.

In another study, comfort food was compared to no food at all, and students’ moods seemed to improve even when they didn’t eat anything—most likely just due to the passage of time.

The take-home message from the studies? While the comfort food may make the person feel better for the time being, it does little to address emotional problems. Of course, everyone can indulge(纵情)in a comfort food from time to time, but overall, aim for these instances to be the exception rather than the rule.

1. Which aspect of comfort food do Tract Mann’s studies focus on?

A．The means by which it affects mood.	B．Its role in reducing negativity.
C．Its impact on physical health.	D．The extent to which it lifts mood.

2. How were the studies carried out?

A．By analyzing questionnaires about comfort foods.

B．By observing students’ different reactions to foods.

C．By collecting data about people from all walks of life

D．By comparing students’ feelings on different occasions.

3. What does the author intend to do in the last paragraph?

A．To explain a rule.	B．To introduce a concept.
C．To make a suggestion.	D．To present a fact.

4. What is a suitable title for the text?

A．The Science behind Comfort Food	B．Comfort Food May not Work Wonders
C．Feeling Negative? Try Comfort Food	D．Comfort Food Tend to Be Unhealthy

6 . It happens from time to time that after a whole morning of studying, you are tired in the afternoon. It is then that you may want to eat something sweet, perhaps a sweet drink or a chocolate bar to lift your mood.     1    

But a study suggests that sugar can make you feel worse rather than lift your mood. The German and UK researchers collected data from 31 studies involving nearly 1,300 adults.     2     Those emotions include anger, alertness, depression and tiredness. They found that people who have too much sugar become more tired and less alert within an hour, and that these feelings become more intense over time.

According to researchers, when people take in sugar, their blood sugar levels rise rapidly, leading to a burst of energy and a short “feel good” period. However, as they begin to digest the sugar, their blood sugar levels decrease quickly, leading to a bad feeling.     3     As with caffeine, this prevents the body from relaxing, leaving people being tired and less alert.

    4     According to WHO, it is healthy to have the sugars found naturally in fruit, vegetables and milk, so long as they make up less than 5 percent of our daily total energy intake.

So the next time you feel tired and can’t concentrate on study and work, perhaps you should think twice before you bite into a chocolate bar. There are still other ways to relieve tiredness.     5    

A．Maybe a little exercise at midday is a better idea.

B．So cutting sweet food out of the diet is a good choice.

C．They studied the effect of sugar on some aspects of mood.

D．After all, it’s believed that a “sugar rush” gives you energy.

E．Sugar in any form is not necessarily good for the human body.

F．But the result of the study doesn’t mean giving up sweet food altogether.

G．To remain on a “high”, people may eat more sugar until they become addicted to it.

8 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

A new study     1     ( make ) last week, provides evidence of an increase in the number of fat and overweight children and young adults worldwide in just 40 years.

The researchers studied fatness     2     young people, between 5 and 19 years old. This was one of the     3     ( big ) epidemiological (流行病学的) studies ever done. They used the information     4     ( get ) the Body Mass Index measurements of the subjects.

The most obvious     5     ( change ) have taken place in Middle Income Countries. WHO defines Middle Income Countries as places     6     a person normally earns between $1,045 and $12,736 every year. The researcher says fatness has     7     effect on children, with some evidence     8     ( suggest ) that it can affect their educational performance.

The report is calling for policymakers to find ways to make healthy food easier to get at home and school,     9     ( particular ) in poor families and communities.     10     also calls for higher taxes on unhealthy food.

9 . More than a third of adults in the United States prefer fast-food restaurants and pizza places on any given day. And the higher their income is, the more likely they are to do so. The Centers for Disease Control and Prevention(C.D.C.) has released data on fast food consumption gathered from 2013 to 2016 in the National Health and Nutrition Examination Survey, or NHANES, a program that continuously monitors the health and nutritional status of Americans.

Fast food — defined(定义) broadly in the survey as any item obtained from a ＂fast food/pizza＂ establishment — is eaten by 37 percent of American adults at some point during the day. Among those who eat fast food, 44 percent do so at lunch and 42 percent at dinner. Men are more likely to have fast food at lunch; women are more likely to snack on it. The most enthusiastic consumers are 20 to 39 years old: 45 percent of them eat fast food on any given day. That figure declines sharply with age, to 38 percent among people 40 to 59, and to 24 percent among those over age 60.

The high rate among 20 to 39-year-olds was particularly troubling. That period sets the stage for health problems later in life — heart disease, dementia(痴呆) and so on. Also, this is the group who have kids, and they’re setting them up for a lifetime of unhealthy eating habits.

The percentage of adults who ate fast food rose with increasing income. About 32 percent of people who earn less than 130 percent of the US poverty line — $32,630 a year for a family of four — ate fast food daily. But 42 percent of people above 350 percent of the poverty line — $112,950 a year or more for that size family — were daily consumers.

A report by the C.D.C. in 2013 estimated that American adults consume more than 11 percent of their daily calories from fast food. Fast food is generally high in calories, fat and salt, a combination that increases the risk for cardiovascular(心血管的) and other diseases. When we hear about a shark attack, we’re scared and we avoid that beach. But what we really should be afraid of is double cheeseburgers and French fries.
