Smaller than your fist, your healthy heart just goes on and on. It will beat more than 60 times a minute for 70 years or more. That’s something that most of us take for granted. But it’s an amazing fact.
60 times a minute for 60 minutes is 3,600 times. What physical thing can most of us do 3,600 times in one hour? Blink? Maybe. Tap our fingers on the desk? No. Jump up and down? Certainly not! But our heart keeps beating, hour after hour. Every day, it pumps almost 2,000 gallons of blood through our blood vessels(血管). It takes you about five years to drink 2,000 gallons of water.
And, unlike your knees or your back, your heart does all this work without ever complaining（抱怨）! You never know that it’s even there. Your heart is such a reliable “silent partner” that people forget to care for it. For many, the first indication（迹象）that their heart isn’t working properly is a serious heart illness! Over 650,000 Americans die of some kind of heart disease every year. Cancer kills 560,000, stroke kills 143,000, and accidents kill 118,000 Americans annually.
Like accidental deaths, many heart disease-related deaths can be avoided if people simply follow the advice of the experts. Unfortunately, most people seem to listen to a little voice in their head that says, “It won’t happen to me. ” So these people keep on smoking and drinking. They continue to eat too much meat. And their only “exercise” is getting off the sofa to get something out of the fridge. Please follow the following steps to keep your heart healthy.

The World Health Organization says there has been a sharp increase in the number of over-weight children in developing countries. In African countries, the WHO says the number of over-weight or obese children is twice as high as it was 20 years ago. Around the world, about 43 million children under the age of five were overweight in 2013.
Overweight and obese children are more likely to become overweight and obese adults. The condition can generate serious health problems like heart diseases.
Francesco Branca is the director of the WHO Department of Nutrition for Health and Development. He says urban lifestyle makes people eat processed food more often ,which has a high sugar ,fat and salt content. He also says people are gaining weight because of their lack of activities. They travel in cars or other vehicles more than on foot.
The WHO experts say to lower obesity rates is especially complex in countries that also deal with high rates of infectious(感染性的) diseases.
The WHO has some basic solutions for individuals and countries. The organization says you should lower your intake of fat, sugar, salt and processed food and eat more fruits,' vegetables and increase physical activity. The WHO says these actions are especially important for children.
And WHO expert Branca says mothers should breastfeed their babies for at least the first six months of life, if possible. More importantly, governments should consider providing vitamins for children and educational campaigns about problems linked to obesity would also help. In his view, government policies should deal with how food is marketed to children and food producers must balance quality and taste with the dangers of sugar, fat and salt.

Those who spend more pre-bedtime hours using the Internet or watching television are more likely to report insufficient sleep, even though they sleep almost as long as people spending fewer pre-bedtime hours in front of a computer or television screen, survey findings show.
“While many people use electronic media, say, the Internet, it should be noted that the longer media use before sleep can trigger (self-perceived) insufficient sleep,” lead researcher Dr Nakamori Suganuma, of Osaka University, Japan, told the reporter.
He and colleagues obtained data on self-perceived sleep problems and the use of electronic media prior to bedtime from 5,875 altogether Japanese respondents in two separate Internet-based surveys. Their findings are published in Sleep and Biological Rhythms.
Nearly half of the respondents associated their problem with electronic media use before bedtime. Longer electronic media users were also more likely to report insufficient sleep.
“Overall, 29% of light users (less than 1.5 hours) listed electronic media use as a possible cause of their insufficient sleep. By comparison, 40% of medium users (1.5 to 3 hours) and 54% of heavy users (more than 3 hours) said the same.
However, longer Internet and television use before bedtime did not correlate with less actual sleep.
While heavy users averaged about 3 more hours in front of computer or television screens than light users, the heavy users averaged only about 12 minutes less pre-workday sleep time than light users.
Notably, Suganuma said, "Internet use affected self-perceived insufficient sleep more than TV watching not only in younger Internet users but also in middle-aged or aged Internet users."
Up to 38% of the respondents listed accessing the Internet far into the night as a possible cause for their sleep disturbance, while about 25% said watching television far into the night caused it.
The findings suggest that while heavy computer and television use before bedtime has a small effect on sleep duration, it may have a more significant effect on "sleep demand and sleep quality," Suganuma notes.
【小题1】 Heavy computer and television user before bed time are more likely to be______ than light ones.
| A．energetic | B．happy | C．sleepy | D．clever |
| A．Heavy computer and television user before bed time have less sleeping time than light ones. |
| B．Heavy computer and television user before bed time have worse sleep than light ones. |
| C．Those suffering insufficient sleep spend less time in using internet than in watching TV. |
| D．Spend less time in watching TV or surfing the internet, and you will have a better sleep. |
| A．be far away from media. |
| B．watch TV rather than use internet |
| C．cut down late-night Internet and TV |
| D．Stop late-night internet and TV |

It doesn’t matter when and how much a person sleeps, but everyone needs some rest to stay alive. That’s what all doctors thought, until they heard about Herpin. Herpin, it was said, never slept. Could this be true? The doctors decided to see this strange man themselves.
Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw him sleeping. In fact, he did not even own a bed. He never needed one.

Good Housekeeping has discovered that even if a child wear a helmet when she bikes, or skates, it may not protect her from a serious head injury.
Every year, 390,000 children under age 15 go to hospital emergency rooms with bike-related injuries. Of that number, about one third children suffer head injuries and an estimated 200 die. By wearing a helmet, a child can reduce her risk of injury by as much as 85 percent. But remember —— a bicycle helmet must fit properly to be safe. Here are five steps to making sure your child's helmet fits properly.
1) If you haven't bought your child's helmet already, you might want to consider one with a rear stabilizer(稳定杆). A rear stabilizer holds the back of the head gently and helps the helmet stay correctly positioned.
2) The helmet should fit closely and shouldn't slide from side to side or front to back. If your child can put two fingers on both temples inside the helmet, it's too big. Try a smaller size. But if the next size down is too small, use the fit pads(护垫). Fit pads come in different sizes and attach to the helmet with Velcro.
3) Tell your child to open her mouth widely and ask if she can feel the helmet push down onto the top of her head. If she can't, you need to readjust her helmet.
4) To prevent strap slippage, wind a rubber band around the strap where it meets the fastener.
5) Recheck the fit regularly.
You should replace the bicycle helmet:
If she has been in an accident with it.
If the buckle(金属扣) breaks or if a piece breaks off.
If it doesn't have a U.S. Consumer Product Safety Commission, American Society for Testing and Materials, or Snell Memorial Foundation sticker.
If it doesn't fit correctly. Even if the helmet fit perfectly two years ago, it might be too small now.
【小题1】Who is this passage mainly written for?
| A．Children. | B．Teachers. | C．Parents. | D．helmet producers. |
| A．The bike-related injury is a serious threat to the children. |
| B．The bicycle helmets must fit properly while the children are biking. |
| C．It’s necessary for the children to wear helmets while biking. |
| D．Many students suffer bike-related injuries every year. |
| A．She must buy a smaller size. |
| B．She can use some fit pads. |
| C．She can put fingers on both temples inside the helmet. |
| D．She must make helmet slide from side to side. |
| A．buy a new bicycle helmet for her |
| B．mend the bicycle helmet himself |
| C．continue to use the bicycle helmet |
| D．throw away the broken buckle |

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢)becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的)circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
【小题1】What is the main purpose of this passage?
| A．To advocate eating more raw and whole foods. |
| B．To tell the differences between raw and processed foods. |
| C．To inform people of the harm of processed foods. |
| D．To warn people of the problem of obesity. |
| A．it is essential for people to protect their vital organs |
| B．foods with natural enzymes help people keep fit |
| C．we’d better be cautious about raw and whole foods |
| D．giving up cooked and refined foods is a new lifestyle |

According to the survey conducted by some scientists, it is common to have difficulty sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift（轮班）work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap (小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications (药物治疗) may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.

Parties and social gatherings no longer excite us the same way they once did. This is not due to a lack of desire to socialize, but the smartphone.
At parties, more people are on their smartphones than on their drinks. According to a recent International Data Corporation study, well over half of all Americans have a smartphone and reach for it the moment they wake up, keeping it in hand all day. In addition, too much of society is using smartphones while driving and as a result getting into car crashes. 34 percent of teens admit to text while driving, and they confirm that text messaging is their number one driving interruption. People's attachment to their smartphones is unbelievably becoming more important than the lives of themselves and others.
Just as drivers dismiss the importance of focusing while on the road, many people also fail to recognize the significance of human interaction. When with their friends, some people pointlessly check or send text messages in the presence of a friend, which sends a message to that friend: the person I am texting is more important than you. In addition, relying on our smartphone to make friends does not give us the same advantage as being able to make new friendships in the real world. Face-to-face conversations will give us much stronger communication skills in the long run.
As many people risk their lives and the lives of people around them just to send a text or mindlessly check their massages, smartphones are in many ways more dangerous to people. The quality of this technology is de-advancing societal achievements and weakening the value of communication. Not only is the smartphone affecting our desire to interact (交流) face-to-face but it is also lowering society's ability to communicate.
【小题1】The purpose of this text is to ______.
| A．call for an end to use the smartphone while driving |
| B．appeal to us to pay attention to communication skills |
| C．express a concern about the overuse of the smartphone |
| D．advise us to be cautious about the addiction to the smartphone |
| A．giving examples | B．listing figures | C．comparing facts | D．analyzing the effects |
| A．by using smartphones | B．in a face-to-face way |
| C．in different ways | D．under a free circumstance |
| A．parties and gatherings limit their social circle |
| B．people are more and more narrow-minded |
| C．people's communication skills are weakened |
| D．face-to-face communication becomes less important |
