Your teenage best friend could be good for your long-term mental health，according to a new study published in the journal Child Development According to the findings, teenagers aged 15 to 16 who had a close friendship rather than a larger group of friends they were less close to had a greater sense of self-worth by the time they were 25 years old. Those people with a very close best friend were also less likely to experience depression and social anxiety, the study found．
“Close friendship strength in mid-adolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood，”the authors, led by Rachel K, Narr，a postdoctoral student focused on clinical psychology at the University of Virginia, wrote.
A past research has suggested that adolescent friendships are important. Friendships during the teenage years predict academic success and improved mental health. But the new research further explores the type of friendships teenagers have. “My hunch（预感）was that close friendships compared to broader friendship groups and popularity may not function the same way,” Narr told Quartz. "Being successful in one is not the same as being successful in the other."
Many study participants did not continue to have a close relationship with their high-school best friend, leading the researchers to wonder what exactly was responsible for the mental health benefits. They suspected that the skills and ability to build such a friendship may be more important than the friendship itself.
And as the researchers point out, those skills are not necessarily brought to bear in the world of social media. "As technology makes it increasingly easy to build a social network of shallow friends, focusing time and attention on developing close connections with a few individuals should be a priority," study co-author Joseph Allen said in a statement.

Nowadays the business of fast food is developing at a rapid speed. Have you ever thought twice before deciding to eat fast food? Even if it is easy to buy and cheap, the risks outweigh(胜过) the five minutes of satisfaction that fast food brings. There are many risks when it comes to eating food that’s made in just a few of seconds.
What you eat can affect your health. People who are addicted to fast food are more likely to suffer from various life-threatening diseases. Obesity(肥胖) can come when fast food is bought often. Fast food is made from a lot of fats and high calories. If it isn’t removed, then you can grow to become obese. Even a small quantity of fast food contains many calories. People are fooled by its appearance and they tend to eat more. Thus, without knowing, they consume a lot of calories. What’s worse, obesity isn’t the only risk. Heart disease is also a danger. The more fats, sugar and salt you eat, the weaker your heart can grow.
Another concern for most consumers is that they can’t keep track of the sources of the food supplies in fast food restaurants. They never know about the living conditions of the animals killed for meat in those restaurants, like cows, pigs, and chicken. A recent study has suggested that bacteria have been found in about 38% fast food. Even some soft drinks are now infected by food-borne illnesses that usually come from meat.
Although fast food is one of the easiest and cheapest ways of eating, the health risks aren’t worth your life, and risking your life for something that isn’t good for you could cost thousands of dollars in hospital bills. It is important to eat healthily and make good choices when deciding what to put in your body. Don’t be lazy and pick up fast food on your way home from work.

Most of the survivors have to stay in the open area overnight after a 7.1-magnitude quake toppled (使倒塌)houses, cut off power and first-aid materials supply in northwest China’s Qinghai Province Wednesday while rescuers face difficulties in searching for the buried.
Rescuers have set up more than 40 tents for survivors in the Gyegu Town, near the epicenter (震中) in the Tibetan Autonomous Prefecture of Yushu in southern Qinghai. But the effort seems far less than enough for the area inhabited by some 100,000 people.
Many people sought temporary shelters in buildings that remained unaffected by the tremor (轻微地震).
In the yard of Yushu’s Sports Committee, nearly 1,000 people were sitting or lying on the ground in sheer (完全的, 十足的) darkness. Some wrapped themselves up with quilts taken out from the debris (碎片, 残骸).
Some brought their own tents and others turned on the lights of motorcycles.
“I’m hungry and thirsty. We’ve been waiting for help since the morning,” said Zhaxi Toinzhub.
The woman said her three children were still buried in the rubble (碎石, 瓦砾).
The National Meteorological Station forecast Wednesday that temperatures may hit minus 3 degrees Celcius at night and 15 degrees Celcius in the daytime in the coming days.
The town would see strong winds and sunny weather in the coming days, providing favorable conditions for rescue operations.
The town is located in a remote area in Qinghai and the quake and ensuing (随后的) landslides have damaged roads, causing great difficulties for rescuers and, especially, machines from outside to enter the region.
“Rescuers had to dig with bare hands or iron sticks Wednesday, looking forward to the arrival of digging machines,” said a rescuer surnamed Wang, who was working at a collapsed hostel.
“The searching operation became even harder at night without lighting facilities,” he said.
In addition, rescuers may easily get exhausted working at a place with an altitude (海拔) of above 4,000 meters.
Thousands of rescuers and medical staff are rushing to Yushu from many regions of China, bringing machines, disaster-relief materials and medicines to the quake-hit town. Governments, organizations, enterprises and individuals are offering donations of money and materials to the region.
