1 . Do you get in trouble for feeding your dog on food from dinner under the table? A new study suggests that by sharing “people food”, you might actually be helping to keep your pet healthy.
Many dogs are fed dry processed food. Science has shown that a diet of processed food is not healthy for humans. Scientists from the University of Helsinki say this diet is not enough with variety (多样化) and good for our pet dogs, either.
The scientists discovered that the foods a dog might find such as eggs, fish, meat and vegetables may be better than a diet of just dog food. Having different kinds of foods leads to many kind of microbes (微生物). There are millions of them in human and animal bodies. Some are detrimental to us, but many are good for us, and they play important roles in helping us digest (消化) food.
A total of 8,500 young pet dogs took part in the study. 4,500 of them were under 6 months old, and the rest were between 6 and 18 months old. The owners were asked about what food they had fed their pets and how often. When the dogs grew older, about 20% of the dogs showed CE symptoms (慢性肠胃不适症状). However, if dogs had had a mixed diet while young, it was 22%less possible for them to experience CE symptoms later in life.
Dr. Anna told The Times of London, “Dog foods on sale are considered to provide a complete diet... But nobody would give 12 years of the same food to a child—why should a dog be different?”

①Sugar-free cookies, reduced-sugar cereal, sugar-free candy, diet soda. Do these seem like healthier alternatives (替代物)? After sugar became something forbidden in the nutrition and fitness world, sugar-free products acted as alternatives for once beloved sweet drinks and snacks. Claiming to be ZERO sugar, they were believed as healthier choices, especially for those people who manage diabetics (糖尿病), or aim to slim down. But the truth is they aren’t equal to better.
②When a product is labeled sugar-free, it means artificial sweeteners are used instead of real sugar. Artificial sweeteners don’t come from natural sources but they are chemical substances that are added to food and drinks to make them sweeter. Actually, most artificial sweeteners are a lot sweeter than sugar, even 200—600 times sweeter, so only a tiny amount is needed.
③Let’s find out how artificial sweeteners work. They work similarly to regular sugar by exciting your taste buds. The taste buds send signals to the brain that they have tasted something sweet and you feel a similar sense as you would with sugar.
④In recent studies, scientists have revealed artificial sweeteners are more harmful to our body than real sugar. Many businesses market sugar-free alternatives as “low-calorie” or “no-calorie”. It misleads people to believe sugar-free products can make them slim and healthy. But it’s reported that you get no nutritional value from consuming them.
⑤What’s worse, when you eat this kind of sweet food, your body continues to desire it even though your body can’t metabolize (新陈代谢) these sugar-free alternatives. Your brain does not know the difference, either. In turn, sugar-free alternatives connect to weight gain and Type 2 diabetes.
⑥Similarly, artificial sweeteners also damage your gut’s ability to break down sugar which affects everything you eat. In other words, your body doesn’t know how to deal with artificial sweeteners because they have nothing real to process.
⑦Here’s a golden rule: stay away from artificial sweeteners and look for non-sugar, natural sweeteners like Stevia or date sugar. In the war against artificial sweeteners and real sugar, both lose. Satisfy your sweet tooth with natural sugars that come from fruits and stay away from products claiming to be sugar-free or diet!

| D．There is still a need for more scientific studies on sugary products whether they are safe or not. |
A． | B． |
C． | D． |
| A. Exercise, or even just spend an hour jogging. You need to move. Even a walk is quite healthy if you can keep it for 30 minutes a day. Walking to the subway and taking it instead of driving a car is a good way to help you exercise more and lose more weight. B. Sleep earlier. Your body has a better rest when you go to bed earlier. Enough sleep helps you to work more effectively. A good sleeping habit will be good for your health. Try to contact your doctor if you can’t fall asleep or often wake up during the midnight. C. Eat more vegetables and cut down junk food. Junk food is bad for your health. It’s hard to change your eating habit in a short time. But don’t forget the fact that health is more important. D. Always have breakfast. A good life starts with a good breakfast, which keeps you in a good mood and full of energy the whole day. Try to develop a good living habit by eating less in the evening. You are sure to feel hungry in the morning. E. Don’t let yourself be very hungry. If you eat something before you are very hungry, you’ll eat less. If you eat right after you find yourself hungry, you’ll eat more than you really need. F. Think twice about joining weight loss programs. Some of such programs couldn’t work for some people. You may get hurt if you don’t follow the correct instruction. To lose weight healthily, you can visit websites such as eDiets. G. Visit your doctor twice a year. Go to a doctor for some tests even if you are well. If you have tests twice a year, you can get to know the problems inside your body as soon as possible. |
4 . Green is more than just a color. It also means taking special steps to protect the environment. How to decide whether a product is green? Here is what we may keep in mind.
The materials of a product are usually our first focus. Green products are made of more natural materials which are free from harmful chemicals, so they can be good for our physical health.
Packaging is important. We’d better choose glass, metal and paper packaging, as these can be reused or more easily recycled. We can also look for less packaging or even choose unbagged products whenever possible.
Location (地点) matters. Think about how much energy was used to get it. To us, try to choose local products. When it comes to food, it is a good idea to order directly from local farmer, shop at markets and buy fruits in season.
Look into what the company tells us about their product. It’s easy to say that a product is “green” or “all natural”, but the words may be too good to be true. So, much of the information about a product should be taken with a grain of salt.
Better than buying is choosing to leave an unnecessary product in the store. It sends a message to the producer, keeps money in our pockets, reduces waste and keeps the planet healthy.

7 . Staffan Lindeberg is a medical teacher at the University of Lund in Sweden. He was interested in a Stone Age diet. In the early 1990s, he began to study the diet of the people on the island of Kitava as it was very close to the Stone Age diet. While there, he found that people did not suffer from (患有) heart attacks, diabetes (糖尿病), being overweight and many other diseases common in western countries.
As a result of his findings, he decided to test patients in Sweden to see how such a diet would affect them. Fourteen patients followed a Stone Age diet while another fifteen followed a Mediterranean diet, also healthy with lots of fruit and vegetables. All of the patients in the tests had high blood sugar levels, most suffered from diabetes and all had heart problems.
At the end of three months, the group following the Mediterranean diet had reduced their blood sugar levels by a small amount but those following the Stone Age diet had much lower levels of sugar in their blood. The patients in both groups also lost weight although the level of sugar in the blood and the patients’ weight didn’t seem to be related.
So, what is it about the Stone Age diet that can make us healthier? The diet contains (包含) some meat, fish, vegetables and nuts (坚果) but it doesn’t contain any milk products or wheat, and there is no salt.
The next question is whether the Kitava people are healthier than us. After all, their life expectancy (预期寿命) is much lower. According to Staffan Lindeberg, this is not as simple as we may think. Because of their poor healthcare, there is more chance of them dying at a young age. However, if people on Kitava manage to reach fifty, they are likely to live as long as people in more developed countries.

8 . About 80% of people do not get enough vitamin (维生素) D every day. But this vitamin is very important for your health.
Vitamin D is really important for our bones (骨骼). When we are young, vitamin D builds up our bones and makes them strong. When we are older, we still need vitamin D to keep our bones strong. Our bodies keep the vitamin D in our bones and teeth. Then we lose vitamin D as we work and exercise during the day. But our bodies can’t make vitamin D. So we have to get it from outside of our bodies.
Where can a person get this very important vitamin? Vitamin D is in foods like fish and eggs. Sometimes, vitamin D is added to bread, milk, and orange juice. Food is not the only way our bodies can get vitamin D. The sun also gives us vitamin D. If we want to be healthy, we should spend some time in the sun each day. Too much sun is not good for you, but about 15 minutes a day is usually enough. And we should be sure to eat foods that are rich in vitamin D, too.
1. Why do we have to get vitamin D from outside of our bodies?| A．It makes us popular. | B．It helps us eat more food. |

9 . We can’t remember clearly since when we started to take our mobiles to a dinner table. This happens a lot, especially when we eat out. Once a dish comes, instead of lifting our chopsticks, we take out our mobiles and click. Later, we post the photos onto Weibo or WeChat, waiting to be “liked”. Then we check our mobiles from time to time during the meal, to see whether we get “liked” or not. We just cannot leave our mobiles for only a meal.
Does that sound familiar to you? Do you do that often? If not, how do you feel when others do that when having dinner with you?
A recent study suggests that what we are used to doing is not so good. Spending time taking photos of food makes the food less pleasant. To test this, some researchers did an experiment. Some people were asked to take photos before they could enjoy food. As a result, it showed that the more photos they took, the less delicious the food seemed to them. So, why not stop taking photos and just enjoy the food in front of you?
Besides the scientific result, there are also some other bad influences of taking photos of food before meals. After posting the photos onto the Internet, one will not be able to control himself and check his mobile many times. “Does everyone like my photos? I hope a lot of people like them!”
It seems that your mobile secretly calls your name all the time, even when you are with real people.
So, next time you go out to have dinner with your family or friends, how about not taking photos of food? Let the food be delicious as it is and share your life with people around you. Trust me, it will be a wonderful time.

10 . Water plays an important role in keeping you healthy. This should come as no surprise. Much of your body is made up of water, after all. It keeps your body working properly. But did you know that too much water can make you die?
Water poisoning (中毒) happens when people drink too much water. This lowers the level of sodium (钠) in their blood to dangerous levels. When you have too little sodium in your body, a lot of things will go seriously wrong in your body.
Your brain may begin to swell (膨胀). You may get a headache, feel very tired and sick. You may even lose consciousness. In these cases, water poisoning can be deadly. You will need to go to a hospital immediately.
Protecting yourself from water poisoning may seem easy, however, this is easier said than done. For example, when you do exercise, you may have to drink a lot of water. It is important to balance the amount (量) of water. This can help you stay healthy whenever you are exercising.
So, how much water should a person drink each day? For years, we have been told to drink two liters (公升) of water a day. But in fact, the actual amount needed is different for each person. Today, most doctors are telling people that they should drink water whenever they feel thirsty.
We can’t live without water. Neither can we live with too much water in our bodies. Make sure you take the right amount of it each day — staying healthy is all about staying balanced.
