Your school asked parents about the social development in children in the last Parents' Meeting. Here are some opinions. Read following information and answer the questions.

    Anew international study shows that some peopled biological clock plays a powerful role for their life expectancy, regardless of lifestyle choices.

Published in the latest issue of Aging on Wednesday, the study has found the most definitive evidence to explain why some people keep healthy lifestyle but die younger than others.

    Geneticist Steve Horvath from the University of California, Los Angeles (UCLA), led a team of 65 scientists around the world to record age-related changes to human DNA, analyse blood samples collected from 13,000 people and estimate their lifespan.

    A higher biological age, regardless of actual age, consistently predicts an earlier death, the study says.

    “You get people who are vegan, sleep 10 hours a day, have a low-stress job, and still end up dying young,” Horvath said in a statement. “We have shown some people have a faster innate aging rate.”

    The findings discovered that 5 percent of the population ages at a faster biological rate, which translated to a roughly 50 percent higher than average risk of death at any age.

    “The great hope is that we find anti-aging interventions that would slow your innate aging rate,” Horvath said, adding that “this is an important milestone to realizing this dream.

    Many animals recognize their food because they see it. So do humans. When you see an apple or apiece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

    Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A land of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

    Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health Choosing the right food, therefore, has become an area of study in modern life.

    From the first use of the rocket to carry satellites into space to the setting up of space stations, human beings have been putting great effort into space research. And so far, we have achieved many successes. But there are still numerous tasks in front of us and we should not stop trying to progress.

    The international space station （ISS） is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word, if we want to explore space more, the first thing we should do is to set up a space station.

    As the space station costs a lot of money, it is hard for one country alone to establish one. The USA seem to be the only country that has the ability to build a space station alone, and it has tried to do so, but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyone's effort and will benefit everyone.

    Led by the U. S. and Russia, the ISS is a joint project between six space agencies involving 16countries. Called the greatest achievement in human cooperation, the ISS has come to the end of a ten﹣year's hard work in construction. China has applied for participation in （taking part in） the project many times. Unfortunately all the applications were rejected, which drove China onto the path of independent development. As the Long March Ⅱ﹣F/T1 carrier rocket blasted off （leave the ground） and successfully carried the Tiangong﹣1into space on September 29, 2011, China takes a big step toward its Space Station Era.

    Some West media suggested that the successful launch of Tiangong﹣1 would disturb the balance of global space power, raising concerns about "China threat". China's space project is not designed for military purpose but for developing space technology to explore space resources and make use of them for mankind's well﹣being.

    Sixty-four-year-old Pierre Deom has spent his entire life close to the woods and fields that he loves. Twice a year, his magazine, La Hulotte, focuses on an animal or plant native to the French countryside.

    The 100th edition was published in November. The magazine counts more than 150, 000 subscribers in many countries, and is doing very well financially. Deom says it all began in January 1972, when he was teaching science in a one-room schoolhouse here." It upset me how the forests and swamps were beginning to be ruined. The word 'ecology' didn't really exist yet. Some friends and I wanted to call attention to the issue. So we said, let's educate the kids. They're ready to hear our message." So he took a step into the unknown, planning to publish his nature journal.

    Deom does all the research and writing and the illustrations (插图) of the magazine by hand. He combines science and humor in his writing and drawing to describe the daily life and sufferings of his creatures. Animals you might overlook or consider dull are magically and vividly brought to life in La Hulotte. "I try to write about animals and plants that are easy to find because I want kids to put on boots, take a magnifying glass, go to the woods and fields to observe and be amazed by what they find," Deom says.

    And it seems to work. Biologist Jerome Fournier began subscribing to La Hulotte when he was just eight years old. "For me it was the first contact with nature when I was a child. And maybe it's the beginning for my life of scientist. I think so."

    What's amazing is its approach. The magazine has realistic drawings and also a little cast of cartoon creatures who comment on things and give a different views. You can read it as an adult or a child; it can be understood on two different levels. So scientists, regular people and children all get something out of it. "It's extraordinary." Fournier says, who works at the Museum of Natural History in Paris, where he says La Hulotte has a crazy following.

During a pandemic (流行病), for many reasons, there are lots of poor parents who are isolated (隔离) with their kids, or roommates who are stuck together in an apartment. But what about the people who have nobody to talk to?

It is common that people feel lonely. However, during the pandemic, this situation can be much worse for experiences like long-time hospital stays or being unable to move due to poor health, disability or age.

Recently, a friendly robot named Robin got a test run in the children's treatment center of the Wigmore Clinic in Yerevan. About as tall as an 8-year-old child, Robin's plastic body and square head may not put you in mind of a human partner, but its face screen containing two big eyes and expressive brows (眉毛) is attractive, which can help children forget their stress for a while.

A hospital can be very stressful for anybody. And the time of treatment and recovery might seem tiresomely long to an adult stuck in a hospital bed. For a child who can't play with his or her friends or sometimes even family, the long course and boring atmosphere seem unbearable. That's where Robin comes in. It can recognize (识别) facial expressions and use the mood of a talk to build personalized, natural conversations and dialogues with a lonely child in the way another child might use. Robin also plays games, tells stories, and makes children take part in various other activities.

According to Expper Technologies, the makers of Robin, during the program with Wigmore Clinic, Robin improved the experience of children in the hospital by 26 percent over those who did not have the chance to play with Robin, and reduced their stress levels by 34 percent during their hospital stay. Mary, whose son was one of those users, said, "Thanks to Robin, my son became happy every day during this pandemic." John Smith, a father of a five-year-old girl in the clinic, told a reporter, "Robin is a great partner. It brings big smiles to my daughter's face."
