    What would you do if you felt anxious(焦虑的)？Would you feel better if someone else could share his or her experiences with you? In the United States, two teenage girls set up a mental health camp called "Healing(治愈)Hearts" to help people deal with anxiety.

    The idea of creating the camp came from Dinah Martinez, 17, and her schoolmate Janet Martinez, 18. Both girls suffered from anxiety.

    Dinah Martinez always did well in school. "But then I just started to collapse(崩溃),"Dinah Martinez said. She stopped talking to her friends, stopped going to school for three weeks and stayed at home.

    Janet Martinez was anxious in elementary school. Things got even worse in junior high. "It was a lot of pressure(压力)I put on myself. I would wake up in the morning and it was like my heart was racing," she said.

    The girls' camp idea got support from Girls Leading Our World (GLOW) in the US. The organization awarded them $ 5,000 to put on the camp for other teenage girls.

    The "Healing Hearts" camp was created to "help deal with anxiety, especially with girls in high school because that's when they are the most vulnerable(脆弱的), "Janet Martinez said.

    On the first day of the camp, 10 girls were there. Experts at the camp talked about anxiety. They helped girls who were experiencing anxiety. The girls learned how to calm themselves when they are anxious. They learned about calming methods like deep breathing and guided mediation(调节).

    "It's good to know that someone else is going through the same thing as me and we can both help each other out," Dinah Martinez said.

    Winter is very cold in many countries. It's easy for you and me to keep warm. If we are cold, we can just buy a warm coat or use a heater and we will feel better. But what about animals? How do they keep warm in winter?

    Some animals migrate(迁徙). This means they travel to places where the weather is warmer. Many birds leave before the winter starts. They fly in groups. If they fly together, the trip will be safer. They like to migrate to the same place every year. Do you know how they can find the same place？Scientists say that birds use the sun, the moon and stars to help them. Other animals like moose(麋鹿) also migrate. Fish and whales swim to warmer water.

    Some animals don't have to leave their homes. They hibernate(冬眠) in winter. They fall into a very deep sleep. The animals' temperature drops and their breathing slows down. Before the winter, these animals must eat much food. If they don't eat enough, they may die while they are hibernating.

    New York is a very large city with more than eight million people. How do so many people move on their way to work or school? In New York you can travel by subway, bus, taxi and private car.

    The subway runs on the railroad lines under the city. Travelling by subway is the fastest way to get around the city. The second way to travel around the city is by public bus. It is a slower way to travel. This is because the traffic is very heavy.

    You can also travel around the city by taxi. This is very expensive, but the taxi will take you to every place you want to go. If the traffic is heavy, the taxi will be slow too.

    During the mornings and afternoons, there is the "rush hour". This is the time when the traffic is very heavy with people going to and from work. The last way to get around New York is using your private car. It is inconvenient（不方便的）because you will perhaps be driving during the "rush hour". The best time to travel around the city is from 9 am to 4 pm, because it isn't the "rush hour".
