    You may not know a lot of people when you start high school. Even if you know some new students, you still feel nervous that you don't know any upperclassmen (高年级学生) and teachers. How are you going to make friends among this sea of unknown faces?

    Most high schools welcome new students before school actually starts. These are helpful not only because you learn your way around the buildings and get to meet some of your teachers, but also because you get to meet new students. That way, when you show up on your first day of school, you may already recognize a few familiar faces.

    When you talk to people, you'll probably find that a lot of them are feeling just like you. They're all new to the school and don't know what to expect. Talking about a common concern with your classmates can help you develop friendships.

    The work in high school is something freshmen are probably worried about. The work in high school builds on what you learned in middle school, giving you a more advanced knowledge of many subjects. So you may find you have more work to do or that it's a bit more challenging (有挑战性的). If you ever find your work too difficult, teachers can give you extra help.

    High school also has more activities after class than middle school, such as clubs, music and theater groups and sports teams. This is a good time to explore your interests and try new things.

    Middle school taught you the basics of academics, time management, and social skills while providing you with a little extra support and guidance. High school gives you the chance to learn how to be more independent (独立的) and responsible (有责任的).

    With the coming of winter, it's the perfect time to get out of town and escape the seasonal mood（心情）disorder. Here are vacation ideas to adopt now.

    Costa Rica

    Costa Rica, located in the Valle del General, is well-known for its coffee, pineapples and sugar cane plantations as well as its rich forests. What's more, you can enjoy horseback riding, spend afternoons at the spa or tour a nearby wildlife shelter to look out for colorful birds, sloths and other animals.

    Los Cabos, Mexico

    If you love wine, travel to Los Cabos, a beautiful vacation destination at the southern edge of the Baja Peninsula. During your getaway, you can enjoy special wine tastings and dinner cooked by Los Cabos's Michelin-starred chef. There are wild-viewing opportunities, too. From December through May, you can spot whales, manta rays and more wildlife.

    Petit St Vincent, the Grenadines

    This private Caribbean island was spared（使幸免）the anger of hurricanes Irma and Maria. What's more, the whole island is only 115 acres and has 22 cottages（小屋）. Each cottage is located in a quiet place, and you can expect to unplug and recharge phones with no wireless connections, television or telephones in the cottage. Even better, you can spend your days admiring fascinating marine（海洋的）life at the Jean-Michel Cousteau Diving Caribbean center.

    The Exumas, Bahamas

    On Fowl Cay's 50-acre private island, you can enjoy a carefree escape. Days can be spent fishing, boating and diving before wandering along white sands. The resort features large one, two-and three-bedroom houses. Best of all, if you're planning a group getaway or multigenerational trip, you rent the entire island for a unique island escape.

    When I was younger, I thought that boys and grown men should not cry. The tears were signs of being weak and a sissy(胆小鬼), which a man is not supposed to be. This was even strengthened in my young mind when the song, Boys Don't Cry, came out in the early 1980s.

    But just this June, I discovered that courage is not all about trying to keep all the pain inside in check. Courage is not all about trying to hide the tears. It is the opposite — the tears strengthen the heart's courage. And I saw this in my father. That day my father cried.

    My 18-year-old sister eloped (私奔) and from it I saw how weak my father's heart was. My sister and I were used to seeing him as an iron-willed figure and authoritarian father.

    For three days after my sister eloped, he would not talk. He would just sit quietly outside our house in the dark. On the fourth night, I sat beside him and asked him to tell me what he felt about everything.

    It has been years since I have laid my hand on my father's shoulder as we have drifted apart (疏远) farther and farther while I was growing up. That night，though, I sensed my father trying to control his pain and I wanted him to be able to let it out. We have all cried over what happened except him. All of us except him.

    The simple touch and my words, "Dad, it is not your fault.", broke my father's dam.

    In the darkness, he began to cry. I felt his shoulders shaking as he whispered, "Where did

    I go wrong? All I ever wanted was for my children to grow up right. Why couldn't your sister wait?"

    I understood then why he preferred to be in the dark. By being there, he hoped to spare his family of a father's pain. His tears, though we did not see them before that night, were there all the same. I saw his courage, that night when my father cried with my hand on his shoulder, and understood his pain.

Dogs are man's best friends—they are very good for children's health. Researchers found that family pets helped to protect babies against breathing problems and infections (感染).

    A team from Kuopio University Hospital in Finland studied 397 babies born at their hospital between September 2012 and May 2015 for their first year. They found that babies who lived with a dog or a cat spent fewer weeks with ear infections, coughs or runny noses. They were also less likely to need antibiotics (抗生素) than babies in homes without a pet.

    Study author, Dr. Eija Bergroth, said dogs brought dirt and bacteria (细菌) into the home, which helped children's immune system (免疫系统) to be strong. This improved their defenses against bacteria.

    As part of the study, parents filled out weekly diaries starting when the children were nine weeks old, recording information on babies' health as well as their contact with cats and dogs. They recorded if they had fever, ear infections, coughs or running noses. They also put down whether they needed antibiotics.

    Based on those diaries, the researchers found that about a third of the children spent most of their first year with a pet dog and 24 percent in a home with a cat. And children with no dog contact at home were healthy for 65 percent of the time, compared to between 72 and 76 percent for those who did have a pet.

    The researchers also found that contact with dogs, more than cats, was tied to fewer weeks of sickness for babies.

    However, the researchers said they couldn't rule out the possibility that people who own dogs are less likely to get sick for another reason, not due to any protection offered by pets.

    A telescope, called Gaia, is being designed by astronomers in Europe, and it couldn't be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth, Gaia will be looking at our entire galaxy (银河系).

    Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia's map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (观察) about a billion stars and other objects in our galaxy. Each object will be observed about 70 times.

    Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle (角度). These two telescopes act like Gaia's “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views.

    Gaia, which is to be sent into space, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair.

    Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.
