Chinese people are eating too much salt. On general, people in China eat about 10.5 grams of salt each day, much higher than the 6 grams advised by Chinese Dietary Guidelines (2016). To solve this, China issued (发布) the first salt reduction guide for its food industry on April 18. The government hopes that can help people have salt in a proper way.
If the guide is followed properly, the salt intake (摄入量) for Chinese people will drop by 20 percent by 2030. The salt we take in mainly comes from processed food. For example, there is about 0.66 grams of salt in a 104-gram can of Lay’s potato chips. That is about 10 percent of the daily salt intake. A 100-gram bag of Kang Shi Fu instant noodles has nearly 2 grams of salt. Therefore, it’s necessary for the companies to reduce salt in their products.
A small amount of salt makes food taste better and is important for good health, but eating too much increases the risk of high blood pressure, heart attacks and strokes (中风), the Xinhua News Agency reported.
Less salt leads to better health. And there’s no need to worry that food will be less tasty in the future. A study found that it’s easy for people to reduce their salt intake. Although you may think your food is not salty enough at first, you will get used to the new taste soon.

【推荐1】Six children were in the hospital. They got infected with E. coli (感染了大肠杆菌). They were very sick, but the doctors didn’t know what caused the infection. They called Dr. Richard Besser. They were sure he would find out.
First, Dr. Besser carefully studied the E. coli the sick children had. He looked at the bacteria’s (细菌的) DNA. The DNA showed that this kind of E. coli was dangerous to humans.
Dr. Besser knew this kind of E. coli could move from animals to humans. Perhaps the children had touched animals that carried the bacteria. Dr. Besser found other E. coli cases (病例) in the place where the children lived. But it didn’t make the answer clear. Dr. Besser then made a list(清单) of what the sick children had eaten. They had all had cheese, apple juice, and fish. He then made a list of what healthy children in the same place had eaten, and compared the two lists. They had had the cheese and fish, but not the apple juice.
Dr. Besser went to where the apple juice was made. He saw that there were animals around the apple trees, and he saw the workers using dirty fallen apples. More importantly, he saw they didn’t wash the apples before the juice was made, and they didn’t heat (加热) the juice to kill the bacteria in it. Dr. Besser then knew it was the apple juice that made the children sick.

【推荐3】Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: green and yellow vegetables of all kinds；citrus(柑橘) fruit and tomatoes；potatoes and other fruit and vegetables；meat of all kinds, fish and eggs；food made from milk；bread or cereal(谷类), rice is also in this kind of food；butter or something like butter.
People in different countries and different places of the world eat different kinds of things. Food is cooked and eaten in many different kinds of ways. People in different countries eat at different times of a day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether food is eaten raw (生的）or cooked, canned (罐装的）or frozen. It doesn’t matter if a person eats dinner at four o’clock in the afternoon or at eleven o'clock at night. The important thing is what you eat every day.
There is a large number of people on the earth. There are two problems in feeding them. The first is to find some ways to make enough food so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food so they can grow to be strong and healthy.

【推荐1】Think about what you like to wear on the weekend. There’s a good chance that you like to put on a pair of blue jeans. At any moment, about half of the world’s population is wearing jeans. But according to a new study, our love for jeans may be bad for Earth, Denim (牛仔布) might be putting some sea animals in danger.
You might wonder. Isn’t denim made of cotton, a natural material? How can it become a danger to nature? Well, in the process of making jeans, cotton is treated with many types of man-made chemicals. Some improve the durability (耐用性) and feel; others give jeans their blue color. Every time we wash our jeans, tiny bits of denim come loose. They flow out of our washing machines, down the drain and into the world’s rivers, lakes and oceans.
Scientists studied the Great Lakes in America and the Arctic Ocean in northern Canada. They found denim waste in all of the water they had collected. It is terrible that the harmful chemicals in denim have spread far and wide. Scientists aren’t yet sure how these chemicals might harm animals.
In the study, the scientists also washed jeans to see how many bits of denim on average each pair would drop per wash. The answer was surprising: About 50,000. Not all of them make their way into the environment. Wastewater treatment plants (污水处理厂) hold back 83 to 99 percent of them. This may sound pretty good. However, one percent of 50,000 bits are still 500 per wash. Now think about the number of jeans around the world and the times each of them gets washed. As a result, a large amount of denim waste still gets into the environment.
Does this mean we shouldn’t wear jeans? Probably not. “We need to buy fewer clothes and only wash them when we truly need to do it.” says Sam Athey, one of the scientists. “You don’t need to wash your jeans after having worn them only a couple of times.”

It is easy to believe that the daily life of a plant is simple and boring. They seem to just stand there and sunbathe. In fact, plants are always busy doing many things. Being rooted in the ground, they must make their own food through photosynthesis(光合作用). Besides, they need to do something to protect themselves from animals that want to eat them. What’s more, measuring light is also one of their daily activities and it helps plants to plan better for the future.
Plants have to measure the changes in the amount of daylight. This helps them to tell what time of the year it is. If a plant is beginning to get more daylight, it knows it’s spring. Because of this, it may then start producing flowers.
If the amount of daylight starts to get low, the plants knows that autumn is coming. It may start to store “food” for its growth. The potato plant, for example, will make tubers(块茎)—the potatoes that we eat.
Plants record not only the amount of daylight they receive, but also the quality of light. Some types of light can better help plants grow. Direct sunlight, for example, works better than light that is being filtered(过滤) through the leaves of other plants. A plant can’t get the right type of light when it is shaded(遮挡) by other plants. It may then begin to grow taller or produce larger leaves in order to get more sunlight.

【推荐3】The human face doesn’t lie. We show sadness and happiness through our expressions. But exactly how many emotions can our face make? Scientists used to believe we had six basic facial expressions that tell others how we feel: sad, happy, surprised, fearful, angry and disgusted (恶心的).
But a new study shows that our faces can do more than we think. Scientists from Ohio State University found out that humans can actually make 21 different facial expressions after studying how people move their facial muscles.
The scientists took pictures of 230 volunteers making faces in response to different cues (提示). These cues included phrases like “you just got some great unexpected news”, which produced a “happily surprised” reaction from volunteers. Other cues included “you smell a bad odor (气味)”, which caused “disgusted” faces.
In total, around 5,000 pictures were taken of the volunteers. The scientists then studied similarities of these pictures using a computer expression database. This helped them to define a facial expression. “That tells us that these 21 emotions are expressed in the same way by nearly everyone,” said Dr. Aleix Martinez to The Daily Telegraph. For example, to express surprise, 92 percent of volunteers widened their eyes and opened their mouth. And 99 percent raised their cheeks and smiled to show being happy.
We are not always aware of our facial expressions, which can hold clues to how we really feel. So these results may have a big impact (影响) on medical treatment. If doctors were able to recognize more complex emotions, it would help doctors treat patients suffering from certain diseases.

【推荐1】How many machines does your family have? What machines do you use every day? Can you live a life without machines? When I was a boy, we had a small machine. It only had one channel. Still, I would always be in my chair when cartoons came on.
The one I liked best was The Jetsons. It was a cartoon about the future that was full of fantastic machines that could do anything. I always laughed when I watched it and dreamt of a day when I would have machines like this to do all my work, so I could just sit back and relax.
Now my life is full of machines like these. ___*___ Just today I had to spend most of the morning on my computer because there was something wrong with it. Last week, I spent most of another morning trying to get my new coffee maker to work right. There seems to be many rules and problems after we have new technology.
But don’t get me wrong. Computers and machines truly help all of us a lot. I just want us to use them without them using us. We always seem to be busy because we’re spending all of our time using these machines.
I hope that in the future, machines can be more user-friendly so we don’t spend all our time on them. With machines we can live an easier life, but they have to work for us.

【推荐2】Many people like visiting ocean parks (海洋公园). It is a great place to learn about sea animals. People can see beautiful sea animals there, and these animals are so special that they bring lots of fun for city people. There are about 3,000 dolphins living in ocean parks around the world. But do they want to go back home? The dolphin in this picture might be able to help them go back to the ocean.
Edge Innovations, a US company (公司), has made a lifelike robotic dolphin (机器海豚). It acts and sounds like a real dolphin. It doesn’t eat and doesn’t get sick. The robotic dolphin weighs about 270 kilograms and can be controlled (控制) by people. It is powered by a battery (电池) and can swim for 10 hours every time. The company hopes these dolphins will take the place of (代替) real dolphins in ocean parks.
In fact, animal lovers are worried about the results of keeping wild animals in parks. The animals have to perform (表演) for visitors many times a day. People around the world are doing more to protect wild animals. Parks and circuses (马戏团) in 20 countries cannot have wild animal shows anymore. For example, ocean parks in France won’t have dolphin shows in the future. Animal rights groups say this is a “great success”. Dolphins will be free soon.

【推荐3】Today, most people are very busy because of long hours’ work, so fast food becomes their first choice most of the time. These might be the food with high calorie and sugar, like hamburgers, fried food and soft drinks. We also see them as junk food.
Our bodies will make a special chemical (化学物质) when we eat junk food. It can make us feel good. But it doesn’t go long. About an hour later, we feel tired and hungry again. Some people solve (解决) this by having more junk food. Same things will happen the next day and never end.These eating habits can bring serious health problems. We may start having problems with our sleep. And we may not remember things well. Doctors tell us to eat less junk food. However, when we feel bad, it’s easy to forget doctors’ advice.
Changing our habits is difficult, but we can try it. If we want some chocolate, have a little. Choose black one—it has less sugar. If you usually go to fast food restaurants, cook the week’s meals on weekends instead and keep them in your fridge. Then, even if you are busy, you can still have a healthy meal.
