These days, people show all kinds of things on the Internet like good food, nice clothes, wonderful vacations and so on. Now showing the number of steps is becoming popular.
Now more and more people find it important to be in good health. To keep healthy, many people go to work on foot. When they start walking, they open the step counter (计步) app on the phones to record (记录) how many steps they walk that day. After a day’s walk, some people show the number on WeChat or Weibo. This can make them learn from each other and keep exercising.
“This helps me to exercise much and keep a good habit,” Miss Liu said. “I can also talk about how to keep healthy with my friends on WeChat. We are in the same group to encourage each other to keep exercising.”
Mr. Wu likes to exercise. But in the past he was kind of lazy and didn’t want to exercise every day. “After I use the step counter app, everything is different. It is great to exercise with my friends. Sometimes there are prizes for those who walk more steps. I really like it.” he said.
Walking is a relaxing and useful way to exercise. Both the old and the young like it. Recording the steps helps people develop a good habit of walking and showing the number can make people more interested in walking. But don’t take the number too seriously.

Heart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants. However, it’s difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects the heart.
But there is now new hope for sufferers of heart disease. According to a study published in the journal Advanced Science, researchers from Israel’s Tel Aviv University printed a 3D human heart on April 15.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” Professor Tal Dvir told CNN.
Unlike the previous 3D-printed heart structure, the new heart is complete with cells, blood vessels, chambers and other structures a heart needs to function normally. But scientists still have more to figure out before the 3D-printed heart can be fitted into the body. For one thing, the experimental heart is only the size of a thumb. And, although it can contract like a muscle, it cannot pump out blood like a real one. At present, the heart prototype is like a tiny airplane that has all of the right parts, but can’t fly.
However, the development is still regarded as a major breakthrough in medicine.
In the experiment, the researchers turned human fat tissue into human heart tissue with stem cell technology. The tissue was then turned into “bio-ink” for a 3D printer to ensure that tissue in the heart came from the patients themselves. So ideally, if it were to be placed in the body of someone in need of a transplant, there would be less risk of organ rejection.
“Patients will no longer have to wait for transplants or take medications to prevent their rejection,” researchers told USA Today. “Instead, the needed heart will be printed, fully personalized for every patient.”
But the scientists think that 3D printing can be used to create other human organs. They foresee a time when the 3D printing of organs will be an everyday medical practice.
“Maybe, in 10 years, there will be organ printers in the finest hospitals around the world and these procedures will be conducted routinely” Dvir said.
1. What’s the function of the first paragraph?| A．To tell us what the major killers are. | B．To explain why it is difficult to have heart transplants. |
| C．To describe how difficult the heart transplant is. | D．To lead into the main topic. |
| A．They cost too much. | B．They are too small. | C．They can’t contract. | D．They are hard to produce. |
| A．It would be made with stem cell technology. | B．It would be made from human fat tissue. |
| C．It would come from a patient’s body. | D．It would be printed according to the patient’s condition. |

【推荐2】Do you know anything about the invention of the bar code (条形码)?
A small food store owner found it was hard to keep records of the product information. In 1948, he asked the Drexel Institute of Technology to solve this problem. Bernard Silver, a graduate student, was interested. He and his friend Norman Joseph Woodland set out to work on it. Finally, they invented their first working system.
The system did work well at first, but it was very expensive and sometimes the system didn’t work well. If the invention was to become popular in stores, the problems had to be solved. Finally, Woodland solved them.
The patent (专利权) for the bar code system was asked for by Silver and Woodland in 1949, but the patent was not given until 1952. Although this patent was given, the system was still not popular with store owners.
In 1970, a business named Logicorn developed the Universal Grocery Products Identification Code (通用杂货产品识别码). Marsh Supermarket in Troy was the first store to set up this bar code reading system. It has become very popular ever since, and now it’s popular in all types of stores all over the world.
1. What do most people think of the bar code at first?| A．Perfect. | B．Useful. | C．Not very good. | D．Terrible. |
| A．was invented by a great scientist | B．system was very cheap after it was invented |
| C．got its patent very fast | D．didn’t become popular until 1970 |
| A．Culture. | B．Health. | C．Nature. | D．Technology. |

【推荐1】People use languages to communicate. Any language has its ways to express people’s minds. One of the ways in common is the use of idioms. An idiom is a group of words. It has a special meaning that is different from the usual meaning. For example, “under the weather” is an idiom meaning ill. So when people say “I’m under the weather”, they are saying that they’re not feeling well. Another example, “in all weathers” means “in all kinds of weather”. So, “There are homeless people sleeping on the streets in all weathers” tells us that homeless people sleep on the streets no matter whether it is cold or hot.
Different languages may have different ways to make idioms. For people who are learning a foreign language, idioms could cause misunderstandings and bring them endless headaches. On the other hand, if things are done right, idioms can also be a fun way of looking into a new culture and understanding how the people think and talk.
Metaphor (比喻) is often used in idioms. Let’s read the following two examples:
●It makes my blood boil (煮沸) when people litter (乱扔).
●The night was dark and quiet; my blood ran cold when I heard a strange noise outside at dark night.
In neither situation above, our blood can reach the point so high or so low in temperature. Yet, with the situations the two sentences created, it is not difficult to work out the unhappy feelings of really angry in the first example and very afraid in the second.
Of course, not all idioms are this easy to understand. When we come to idioms of a foreign language, a good dictionary of idioms is always suggested.
1. This passage tells us something about ________ in the English language.| A．grammar | B．writing | C．reading | D．idioms |
| A．I’m under the weather | B．I’m there in all weathers |
| C．You’ve made my blood boil | D．My blood runs cold |
| A．We should look it up in a good idiom dictionary. |
| B．We should try to express our minds with it. |
| C．We should find an interesting way to learn it. |
| D．We should create situations to guess its meaning. |
| A．Positive. | B．Negative. | C．Neutral (中立的). | D．We don’t know. |

【推荐2】Bright blue fire in the night sky
It's exciting to watch colorful fireworks. But have you ever noticed that you don't see blue fireworks very often? It turns out that blue is the most difficult color to make for fireworks. This is firstly because the evening sky is blue. It means blue does not show up very well. You have to make the blue very bright so that it will stand out from the sky.
However, it's not easy to make bright blue fireworks. Different firework colors are made by mixing different elements (元素) together. When the elements start burning, they release different wavelengths of light, which become different colors. Blue needs just the right balance of several chemicals (化学物), as well as the element copper (铜). The temperature of the flame(火焰) must also be strictly controlled, which is hard to do.
So if you are lucky enough to see blue fireworks, you should cherish and enjoy them.
