2 . Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock     1    . Here is how to make one.

•     2     In order to make a change, you need to decide why it’s important. Do you want to get up in time to have breakfast with your family, get in some exercise or just be better prepared for your day? Once you are clear about your reason, tell your family or roommates about the change you want to make.

• Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags.     3     That’s a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.

• Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating (弥补) on the weekends actually feeds into your sleepiness the following week, a recent study found.     4    .

• Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record.     5     If not, take another look at other methods you could try.

A．Get a sleep specialist.

B．Find the right motivation.

C．A better plan for sleep can help.

D．And consider setting a second alarm.

E．If the steps you take are working, keep it up.

F．Stick to your set bedtime and wake-up time, no matter the day.

G．Reconsider the 15 minutes you spend in line at the cafe to get coffee.

3 . There is an English saying: “    1    “ Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body.     2    

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise.     3     If laughter exercises the body, it must be beneficial.

Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated the pain for the longest time was the group which listened to a funny program.     4    

    5     They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

A．Laughter can prolong one’s life.

B．As a result of these discoveries, some doctors in the United States now hold laughter clinics in which they help to improve their patients’ condition by encouraging them to laugh.

C．The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.

D．It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach and even the feet.

E．Although laughter helps cure the disease, doctors still cannot put this theory into clinic practice.

F．Laughter is the best medicine.

G．They have found that laughter really can improve people’s health.

4 . What you do after studying could have a big effect on how well you learn and remember. Today on Education Tips, we will explore two no-cost ways that can help you improve your learning: wakeful rest and sleep.

When many students finish studying, they often go straight to another activity. Perhaps they look at their phone or computer. They might even play a video game or watch television. But research suggests that resting after your study may help you remember what you have studied.

The basic idea is this: by stopping your activity after the study, your brain gets a chance to rest. Resting is difficult when you are playing computer games.

While this might sound unusual to you, many studies have explored the benefits of resting after learning—what is called “wakeful rest”.

A 2019 study found that both young and older adults were able to better remember information they learned after doing wakeful rest.

If you want to give “wakeful rest” a try, here are a few simple things to do. Rest quietly for five to ten minutes. Do not look at your phone, read stories or play games. It is really that easy!

Besides wakeful rest, sleep is also important for learning. The Division of Sleep Medicine at Harvard Medical School (HMS) notes that sleep helps people to learn in two ways. A report on the school’s website explains that “a sleep-deprived person cannot focus attention well and therefore cannot learn well”. It also says, “Sleep itself helps us to memorize and that memorizing is very important for learning new information.”

The National Sleep Foundation (NSF) suggests that adults between the ages of 20 and 64 get between 7 and 9 hours of sleep per day. Teenagers may need a little bit more, and people over the age of 65 may need a little less.

Try to get some “wakeful rest” after a study. Then try to get a good night’s sleep. That’s it—a simple, no-cost way to help you remember what you learn.

1. What is paragraph 3 mainly about?

5 . The Dangers of Secondhand Smoke

Most people know that cigarette smoking is harmful to their health. Scientific research shows that it causes many kinds of diseases.     1     However, Edward Gilson has lung cancer, and he has never smoked cigarettes. He lives with his wife，Evelyn，who has smoked about a pack of cigarettes a day throughout their marriage. The Gilsons have been married for 35 years.

    2     However, doctors believe that secondhand smoke may cause lung cancer in people who do not smoke because nonsmokers often breathe in the smoke from other people’s cigarettes. The US This smoke is called secondhand smoke.

Environmental Protection Agency reports that about 53，000 people die in the United States each year as a result of exposure to secondhand smoke.

The smoke that comes from a lit cigarette contains many different poisonous chemicals. In the past, scientists did not think that these chemicals could harm a nonsmoker’s health.       3     They discovered that even nonsmokers had unhealthy amounts of these toxic (有毒的) chemicals in their bodies.     4     For example，we cannot avoid secondhand smoke in restaurants，hotels and other public places. Even though many public places have nonsmoking areas，smoke flows in from the areas where smoking is permitted. It is even harder for children to avoid secondhand smoke. In the United States，nine million children under the age of five live in homes with at least one smoker.

Research shows that children who are exposed to secondhand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as the children of nonsmokers. The risk is even higher for children who live in homes where both parents smoke.

    5     As a result，they have passed laws which prohibit(禁止) people from smoking in many public places.

A．Recently, though, scientists changed their opinion after they studied a large group of nonsmokers.

B．As a matter of fact, almost all of us breathe tobacco smoke at times, whether we realize it or not.

C．In fact, many people who smoke get lung cancer.

D．However, secondhand smoke is dangerous to all people, old or young.

E．People are becoming very aware of the dangers of secondhand smoke.

F．No one knows for sure why Mr. Gilson has lung cancer.

G．Many people, including doctors, parents, teachers, and others, are concerned about the health risks of cigarette smoking.

6 . Mathew White, an environmental psychologist, is on a mission to give Mother Nature the respect he thinks she deserves when it comes to human health. For decades, scientists and health-care professionals have recognized that exposure to green spaces, such as public parks or forests, is linked with lower risks of all sorts of illnesses common in the world. Experimental work has demonstrated various physiological responses that occur when people spend time in natural environments: blood pressure drops, heart rate decreases, immune function improves, and the nervous system directs the body to rest and digest.

As humans increasingly populate urbanized areas, they are spending less and less time in natural environments. But before doctors can start advising their patients to head to the nearest park, there is an important outstanding question, says White: How much time in nature do you need to generate these apparent benefits? Most of the research that has linked health outcomes with exposure to the natural world didn’t use frequency or duration of park visits, but rather the amount of green space within a certain distance of a person’s home, White says. But “it’s not so much where you live; it’s whether you use it or not.”

So he collected data to estimate what dose（剂量） of nature was needed to show benefits to a person’s health. White’s group found the answer he was after: Spending at least two hours in nature per week was strongly correlated with self-reports of being in good health or having high wellbeing. “I was very surprised, to be honest,” says White, who had been expecting a much longer time. “We had no idea that such a clear threshold of time per week would emerge from the data.”

He was further surprised to learn that it didn’t seem to matter how many trips to a park people took, so long as they got in their two hours per week. It could be a long visit one day, a couple of hour-long trips, three visits of 40 minutes, or four half-hour excursions. He and his colleagues speculate that, if nature’s apparent health benefits are a result of being able to de-stress, then whatever pattern of green space exposure fits one’s schedule is probably the best way to achieve that goal.

Health-care recommendations for people to spend time in nature are probably years away, but the movement has begun. Several organizations around the world are working to promote awareness of nature’s contribution to health. Some researchers have used the term “a dose of nature” to evaluate the amount of exposure needed to gain benefits. “That was kind of the deliberate medicalization of the language around nature and health,” says White.

1. White’s research focused on_______.

A．required amount of green space

B．benefits from the exposure to nature

C．necessary time length of nature visits

D．physical responses to outdoor activities

2. What does the underlined phrase “threshold of time” in Paragraph 3 probably mean?

A．is confident about his mission

B．is willing to cooperate with others

C．has persuaded others to accept his idea

D．has adopted the term for his research result

4. What’s the best title for the passage?

A．Respect for Nature	B．Nature as Medicine
C．Present from Nature	D．Mission in Nature

7 . Is Fresh Air Really Good for You?

We all grew up hearing people tell us to “go out and get some fresh air.”     1     According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

    2     If the air you’re breathing is clean—which it would be if you’re away from the smog of cities—then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉) and your brain.

Recently, people have begun studying the connection between the natural world and healing(治愈).     3     In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪).Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead.     4     It gives us a great feeling of peace.

    5    While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D   . To make sure you get enough Vitamin D—but still protect your skin—put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D   .

A．Fresh air cleans our lungs.

B．So what are you waiting for?

C．Being in nature refreshes us.

D．Another side benefit of getting fresh air is sunlight.

E．But is fresh air really as good for you as your mother always said?

F．Just as importantly, we tend to associate air with health care.

G．All across the country, recovery centers have begun building Healing Gardens.

8 . 七选五根据短文内容，你的生活从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

Nowadays a vegetarian (素食的) lifestyle is becoming more and more popular. Keeping a vegetarian diet is one of the best things we can do.

    1    A well planned vegetarian diet provides us with all the nutrients (营养素) we need and avoids fat, cholesterol (胆固醇) found in animal flesh, eggs, and dairy foods. And it can provide protection against various kinds of diseases, including the three biggest killers: heart disease, cancer, and other serious diseases. The American Dietetic Association states that vegetarians have lower rates of death from heart disease, lower blood cholesterol levels, lower blood pressure and lower rates of high blood pressure.    2    Scientists have also found that vegetarians have stronger immune systems than their meat-eating friends.    3    Vegetarians live, on average, 6 to 10 years longer than meat eaters.

    4    Animals raised for food consume the vast majority of their calories simply in order to live, just as we do. We feed more than 70 percent of the grains to farm animals. So it’s really a huge waste, isn’t it? Try your best to find tips on the health benefits of a vegetarian diet.    5    

A．Growing all the crops needed to feed animals requires great amounts of water and land.

B．This means that they are less likely to be affected by everyday illnesses like the flu.

C．Vegetarian diets are the only diets that work for long term weight loss.

D．All of these diseases are more likely to happen to meat eaters.

E．Healthy vegetarian diets support a lifetime of good health.

F．It’s never too late to turn over a new page.

G．Living on plants also saves energy.

9 . Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self­conscious (难为情) when they’re in poorly lit places—and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.

Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it’s time to repaint, go blue.

Don’t forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12­inch plate instead of a 10­inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.
