1 . The tooth is the hardest part of your body. Your teeth help you in many ways. For example, they can help you talk. They can also help you have a great smile. And the most important job of your teeth is to chew (咀嚼) your food. But do you know how your teeth grow?

When you are born, you don’t have any teeth. About 8 months later, small teeth begin to appear one by one. These teeth are called baby teeth. They are also called milk teeth. You won’t have baby teeth forever. They usually begin to fall out when a child is about 6 years old. Then, permanent (永久的) teeth begin to appear. These teeth are larger and more powerful. Most people will have 28 permanent teeth by the time they are 12 years old.

For some people, four more permanent teeth arrive by their 25th birthday. They are called wisdom teeth (智齿). But these teeth don’t make you smart! Sometimes they bring you pain. If a wisdom tooth brings you too much pain, you should go to a dentist (牙医) and have it pulled out.

2 . My father was the kind of guy who could walk into a room full of strangers and leave with new best friends for life! He was a hard worker and was known as “Mr Fix-It” to everyone. He was also one of the most cheerful, affable (和葛可亲的) and gentle people you would ever meet, which made us, his beloved daughters feel proud.

But when Dad was in his fifties, my family began to notice him struggling. His work and skills began to become worse and worse, and he became depressed and withdrawn. This was not the man I knew. At the age of fifty-eight, Dad was diagnosed with early-onset Alzheimer’s disease. As for our family, it was the worst.

Our first step was to attend a meeting hosted by the Alzheimer’s Association to learn more about the disease and programs that might help us. That meeting inspired me to start a Walk to End Alzheimer’s^® team. But I still wanted to do more. In 2017, I became a board member of the Alzheimer’s Association Delaware Valley Chapter.

The loss from this disease is gradual. My father’s decline continued for several years. Losing my father more and more each day was leaving a big hole in my heart and my life. I decided to fill that hole with action to honor my father.

That’s why I recently decided to leave a gift to the Alzheimer’s Association by naming it as a beneficiary of my retirement plan. My future gift will provide money to support research because I don’t want another person in my family or someone in other families to have to suffer from Alzheimer’s disease.

I am so proud to be able to honor my father and other family members who lost their fights to Alzheimer’s in this way. My dad was an inspiration to me, and I hope, through my gift, I can inspire others to join in the fight to end Alzheimer’s.

4 . A 71-year-old Swedish man “can’t put into words” how thankful he is for the new technology that quickly flew him into the small category of only ten percent of people who survive sudden heart stopping.

The man now has made a full recovery and returned home, after the speedy delivery of a defibrillator(除颤器)—via autonomous drone(无人驾驶飞机). The company behind the drone pilot project says it’s the first time in medical history, a drone has played an important part in saving a life during a heart stopping.

He was in his driveway when the attack happened. Normally, you have about ten minutes to get help in such a situation. Luckily, a telephone call was immediately placed requesting emergency services and he lived in a region that had partnered with Everdrone’s innovative life-saving programme called EMADE (Emergency Medical Aerial Delivery service). EMADE drones delivered a defibrillator to the scene—and the amount of time from the alarm(警报) until the defibrillator was safely delivered at the doorstep of the incident address was just over three minutes.

Even luckier, a doctor happened to be driving by and stopped to see if he could help. “I was on my way to work at the local hospital when I saw a man collapsed in his driveway and I immediately rushed to help,” says Dr. Mustafa Ali. After the ambulance arrived, the patient was rushed to the hospital.

The man said, “If it wasn’t for the drone I probably wouldn’t be here.”

275,000 patients in Europe and 350,000 in the US, suffer from heart stopping annually. About 70% of heart stopping occur in private homes without defibrillators on site. The chance of survival decreases by 7%—10% with each minute following the collapse(突然倒下)—and as a result, the current survival rate among heart stopping patients is merely 10%.

1. How’s the 71-year-old Swedish man now?

A．He is much better in hospital.	B．He is very fine at home.
C．He still needs a defibrillator.	D．He’s made a recovery in hospital.

2. How long did the old man wait for to be saved with a defibrillator?

A．About 20 minutes.	B．About 10 minutes.
C．About 8 minutes.	D．About 4 minutes.

3. Why was Mustafa Ali able to help the old man?

A．He was there by accident.	B．People called him for help.
C．He saw a drone with a defibrillator.	D．People rushed to him for help.

4. What can we infer from the last paragraph?

A．Most people in Europe and the US die from heart stopping.

B．Saving people with heart stopping quickly is important.

C．Most people can’t afford expensive defibrillators.

D．It’s necessary for every family to prepare for a defibrillator.

5 . Why late-night eating is something you should absolutely avoid? It’s long been popular advice for people looking to lose weight to avoid late night eating. It’s no wonder, with a host of research showing that late-night eating is linked to greater body weight. But until now, few studies have actually investigated why. This is what a recent U.S. study set out to uncover.

Researchers had 16 participants follow two different meal schedules, each for a period of six days total. The first group had their meals early in the day with the last meal consumed six hours and 40 minutes before bedtime. The second group had their daily meals four hours later. This meant they skipped breakfast and instead had lunch, dinner and an evening meal. Their last meal was consumed only two and a half hours before sleep. All the participants consumed an identical diet, and all of their meals were equally spaced with around four hours between them.

The researchers looked at three measures associated with weight gain: the influence of appetite, the impact of eating time on calories burned, and changes of fat tissue. They found that compared to an early eating pattern, late eating not only increased feelings of hunger the following day, it also increased the rate of “hunger” hormones (激素) in the blood. Late eating also caused a decrease in calories burned the following day. Fat tissue samples taken from the participants also showed the increased fat storage. These results indicate that late eating could lead to weight gain.

Given the study was only conducted on a limited number of participants and over a very short time, more research will be needed to further understand whether these changes are only temporary, and what effects long-tern late-night eating can have on the weight gain mechanisms (机制).

Anyway this study adds to a growing body of evidence showing just how important meal timing can be when it comes to body weight. Therefore, people who are watching their weight may want to ditch the late-night snacks and favor eating most of their meals earlier.

1. What is the study designed to do?

A．To promote suggestions on losing weight.

B．To prove the findings of the past research.

C．To see why late-night meal causes weight gain.

D．To figure out which is the better meal schedule.

2. Which of the following is a result of late eating?

A．The slow intake of nutrition.

B．The decreasing feeling of hunger.

C．The increase of blood pressure.

D．The great accumulation of fat.

3. Which of the following best explains “ditch” underlined in the last paragraph?

A．Sell.	B．Quit.
C．Delay.	D．Taste.

4. In which part of a newspaper may the text appear?

A．Medical Stories.	B．Healthy Eating.
C．Life and Fashion.	D．Sports and Fitness.

Eat for your eyes

We all know carrots can support eye health, but there are also a bunch of other fruits and vegetables that are beneficial. Mainly, you want produce that contains vitamins A, C, and E, which can help prevent some diseases like cataracts. Look for dark-colored vegetables such as peppers and sweet potatoes.     2

To help reduce this strain, experts recommend following the 20-20-20 rules.     3     Taking these little breaks can help avoid eye strain. Of course, it’s not a bad idea to keep your eyes away from a screen for an entire day every once in a while.

Wear eye protection

It’s always a good idea to wear something in situations that might put your eyes at risk, whether you’re playing sports or doing construction work.     4     so it can happen to anyone. With simple eye protection, you can easily avoid permanent injury to your eyes.

7 . The first appointment this month was for high fever, the second for red eyes and now your child has a cough. With limited time off at your job, there’s no way you are taking him to the clinic again this month. You decide Dr. Google will work as you enter symptom into your search box. You’re not alone!

While online self-diagnosis (自我诊断) resources seem like savers in our moments of confusing illness, healthcare professionals see dangers in this practice.

For some, it’s a simple math equation: Symptoms + Internet search = You’re probably dying. “People read about the worst possible situation on Google when they look up their symptoms. This can contribute to great stress,” says Dana Corriel, a Primary Care Physician at Highland Medical. “It’s human nature to worry about the worst possible outcomes.”

Besides, Corriel warns of health blogs written by people unqualified to be giving advice. “Often, the information is too general,” Corriel explains. “Each person has a different family history, different risk factors and a varying social history, all of which contribute to the decision-making process a physician goes through when deciding on a proper diagnosis.”

“While an inaccurate diagnosis can be stressful, the greater risk is that patients take the next step in attempting to treat,” says Nicole Prause, a psychologist and researcher at Liberos. “This can lead to unjustified expense at the least and dangerous effects at worst.” Prause also sees the financial burden of unnecessary testing with the amount at 20- and 30-year-olds now requesting MRIs because they have headaches. The undue stress damages your emotional well-being, and it’s expensive for the patient, the insurance company and the medical provider.

Even after understanding the dangers of self-diagnosis, you can’t get past the convenience of using the Internet. It’s important to know that doctors do not intend to prohibit their patients from playing an active role in healthcare. The key is to be careful of the risks, involved with self-diagnosis and to be able to identify sources of information with an attitude of doubt.

8 . If you hope to improve your health, exercise is obviously a good way. But do you know that it has great effects on the mind too? We often pay little attention to the great mental benefits that exercising regularly can have. It will allow you to stay active and healthy for a long time, allowing you to have both the physical and mental (身心的) benefits.    1    

Improve your mood (心情) . Exercise is just what you need if you’re looking for some positive feelings. It is possible that you have experienced a happy time after exercise. While you are exercising, “happiness hormones (荷尔蒙)” are released.     2    

Reduce stress. If you’re feeling stressed, this feeling will disappear after exercise.    3    Because it helps reduce the level of the “stress hormone” which leaves you feeling tired and stressed.

    4    If you take regular exercise, you’ll find the results last longer too. So over time, you’ll have a higher ability to stay focused while completing tasks if you exercise regularly.

Improve your memory. According to a study by the University of British Columbia, regular exercise increases the size of the hippocampus (a part of the brain).    5    

So, it is clear to see that there are many different benefits regular exercise can have. With these benefits for the mind, there now shouldn’t be any excuse not to start and lead an active, balanced life.

A．Increase your focus.

B．Increase your sense of self-worth.

D．They fill you with positive and happy feelings.

E．Exercise is a quite wonderful way to reduce stress.

9 . How to lead a healthy life

Have you ever made the resolution to lead a healthy life? And what did you do for it? Leading a healthy life means that you should take charge of your own habits and actions.    1    

Get enough sleep.     2     Enough sleep can help maintain your immune resistance(抵抗力), your weight, and your mental health. Try to go to bed naturally around the same time every evening so that your body knows it’s time to relax.

    3     Make sure you move every day. It will help to improve your mood, your energy, and your health. If you’re an adult, you had better spend 75 to 150 minutes doing aerobic activity(有氧运动)a week. Actually, it’s better to exercise more frequently than to get all your working out in one day, so do something daily if you can.

Build happiness and self-acceptance.    4    Therefore, it’s necessary to get in the habit of treating yourself lovingly. Speak to yourself the way you would speak to a dear friend. And if you have a positive thought, try to say it out loud.

See your doctor regularly. Get your annual check-up, and see a doctor whenever you think something might be wrong.    5    Your doctors will be more likely to discover a potentially serious illness or condition early, which can help them treat it more effectively.

A．Take proper exercise daily.

B．Sleep has much to do with health.

C．Get all your working out in one day.
