    Students perform less well in final exams if smartphones are allowed in class, for non-academic (非学业的) purposes in lectures, a new study in Educational Psychology finds. Students who don't use smartphones themselves but attend lectures where their use is acceptable also do worse, suggesting that smartphone use damages the group learning environment.

    Researchers from Rutgers University in the US performed an in-class experiment to lest whether dividing attention between smartphones and the lecturer during the class affected students' performance in within-lecture tests and a final exam. 118 students at Rutgers University took part in the experiment during one term of their course. Smartphones were not allowed in half of the lectures and allowed in the other half. When smartphones were allowed, students were asked to record whether they had used them for non-academic purposes during the lecture.

    The study found that having a smartphone didn't lower students' scores in comprehension tests within lectures, but it did lower scores in the final exam by at least 5%, or half a grade. This finding shows for the first time that the main effect of divided attention in the classroom is on the length of time in keeping memory, with fewer things of a study task later remembered. In addition, when the use of smartphones was allowed in class, performance was also poorer for students who did not use them as well as for those who did.

    The study's lead author, Professor Arnold Glass, added: "These findings should alarm students and teachers that dividing attention is having a not obvious but harmful effect that is damaging their exam performance and final grade. To help manage the use of smartphones in the classroom, teachers should explain to students the alarming effect—not only for themselves, but for the whole class."

    This is the first-ever study in an actual classroom showing a relationship between losing attention from smartphones and exam performance. However, more researches are required to see how students are affected by using smartphones after school.

Your action can speak louder than your words. It is important to know another language and how to communicate without words when you are in another country. Before saying anything, people communicate with each other by using gestures. However, many gestures have different meanings, or no meaning at all, in different parts of the world.

In the United States, nodding your head up and down means "yes", while in some parts of Greece and Turkey, it means "no". In the southeast of Asia, it is a polite way of saying "I heard you".

Today in the USA, when someone puts his thumb up, it means "Everything is all right." However, in Greece it is bad manners to do so. Also putting your clasped hands up above your head means "I am the winner." It is the sign which players often make. In Russia it is the sign of friendship.

In the USA, holding your hand up with the thumb and index finger in a circle, and the other three straight means "Everything is OK." In France, it means "You are worth nothing."

It is also important to make eye communication. If you look down when talking to an American, he or she may feel that you are shy, or you are trying to hide something.

Besides these, you should also know there are some topics that can not be talked about, such as age, weight and marriage. You can talk about the weather, work, sports, food, where one lives and news of the day.

Healthy Habits, Healthy Body

Feel tired lately? Has a doctor said he can't find anything wrong with you？ Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you.

Then, consider this: you might be in a state of subhealth(亚健康).

Subhealth, also called the third state or gray state, is explained as a borderline state between health and disease.

According to the investigation by the National Health Organization, over 45 percent of subhealthy people are middle­aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam weeks.

Symptoms(症状) include a lack of energy, depression (压抑), slow reactions, insomnia (失眠), agitation, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.

The key to preventing and recovering from subhealth, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open­air activities.

As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruit and fish because they are rich in nutritional elements－vitamins and trace elements that are important to the body.

Nutrition(营养) experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化系统). They also say that a balanced diet is very helpful in avoiding subhealth.

Tips for Green Travel with Kids

Traveling doesn't mean letting go of all the eco－friendly choices we work so hard to achieve in our daily life. Here are a few tips for green travel with kids：

Booking nonstop flights whenever possible will reduce carbon emissions (碳排放). If the closest local airport doesn't have nonstop flights to a certain place, check in with other local airports to see if nonstop flights are available.

Whether you're flying or driving, it's easy when traveling to pull into fast food restaurants for snacks.  My kids love to help plan snacks. I let them create their own snacks for the trip at home.

 At the airport, keep your reusable bottles empty until you have passed through the security (安检). Fill them up on the other side of the security checkpoint. Single－use plastic water bottles create unnecessary waste and the plastic can be harmful to your health.

 Open a few windows and turn off the air conditioner (空调). You should also help your children keep their good, green habits from home to place while traveling. Sometimes vacation can mean more than one shower each day—once in the morning and again after getting out of the pool. Pay attention to the number of showers and the length of showers.

A. Walking is good for your health.

B. Try to cut back to save water and energy.

C. But you can pack healthy food from home.

D. Traveling is a great chance to introduce your kids to the world.

E.Reusable water bottles are easy to bring along wherever you travel.

F.Save energy by turning off the hotel room lights when you head out for the day.

G.You might have to drive a bit further, but saving on carbon emissions makes it worthwhile.

Every year, many dolphins worldwide are captured (捕获) and kept in small pools, performing for people, especially children. These dolphins are fed fish instead of having to1them. As a result, they start spending most of their time near the pool rather than underwater. They get out of shape and can no longer2long distances. It affects their3greatly, and has proved to have4consequences.

Thus comes the question, "Should captive dolphins be5?"

Jeff Foster, a 55-year old expert, decided to help two captive dolphins, Tom and Misha, to reach their top physical6. Every day, he used to train the two dolphins to get used to their wild homes again. Twenty months later, Tom and Misha began to act like7dolphins and they were set free back into the sea.

8Tom and Misha lived in captivity for 4-5 years, they were able to adapt to the wild. It was9what Foster had hoped for. His dreams for the dolphins had finally come true and he knew that the dolphins would10in the wild.

This program was a big success, but there have been others that failed. For example, another dolphin, Keiko, returned into the ocean in 2002, but11a year later because of all the misery (不幸) he12. The sudden environment change did not13him well.

If people want to avoid these accidents, we must go to great lengths and put in the14to ensure it doesn't happen ever again. In fact, with virtual reality technology picking up, there can still be great ways to15kids with sea animals without having to capture dolphins.

Dear Editor,

A young and successful manager was traveling down a neighborhood street, going a bit too fast in his new Jaguar. He was watching for kids darting out (窜出) from between parked cars and slowed down when he thought he saw something. As his car passed, no children appeared. Instead, a brick hit violently into the Jags side door! He stepped on the brakes and backed his Jag back to the spot where the brick had been thrown.

The angry driver then jumped out of the car, grabbed the nearest kid and pushed him up against a parked car shouting, "What was that all about and who are you? Just what the heck are you doing? That's a new car and that brick you threw is going to cost a lot of money. Why did you do it?"

The young boy was apologetic. "Please, mister... please, I'm sorry but I didn't know what else to do," he explained. "I threw the brick because no one else would stop…" With tears rolling down his face and off his chin, the youth pointed to a spot just around a parked car. "It's my brother," he said. "He rolled off the sidewalk and fell out of his wheelchair and I can't lift him up." Now sobbing, the boy asked the astonished manager, "Would you please help me get him back into his wheelchair? He's hurt and he's too heavy for me."

Moved beyond words, the driver cooled his anger.

……

The driver watched the boy push his wheelchair-bound brother down the sidewalk toward their home.
