    Bob is my cousin．He is only five years old．He likes eating meat(肉)very much．He always has meat for lunch and dinner．He doesn't like vegetables or fruit. So he is a little fat．My aunt worries(担忧)about him and doesn't want him to have so much meat．

    It's Sunday．Bob and my aunt go to the zoo to see animals．They see tigers and bears．Bob likes them very much．Then it's time for lunch．The keepers(饲养员)bring some meat for the tigers and bears． 

    "Mum, do tigers and bears have meat every day?"Bob asks．

    "Yes，they do，"my aunt says．"It's time to have lunch．Let's eat out. What do you want for lunch?"

    "Meat．"

    "Oh, Bob．You're a little fat．Eating much meat is not good for you."

    "No, Mom．Tigers and bears eat meat every day，and they're very strong-I want to be strong，too．"

    There is a 41-year-old woman from California known as Anna, and she remembers almost every day of her life since(自从)she was eleven. There is an 85-year-old man known as Eddy, and he only knows a little.

Eddy is warm and friendly. He laughs a lot. He looks just like any other grandfather in the world. But 15 years ago  he was sick. Then he only knows the people in the room with him. Every morning, he gets up, has breakfast, and then goes back to bed to listen to the radio. Often he forgets that he has done these things. Sometimes he has breakfast three times in the morning.

    For Anna, the past is always there. She remembers the person giving her a call at 12:34 pm on Sunday, August 3, 1986. She remembers that on March 28, 1992, she had lunch with her father at the Beverly Hills Hotel. She remembers the food and every word of the talk. She remembers the weather.

    Anna said, "I remember the good things and that is nice. But I also remember the bad things. Ten years later, I still get angry with myself for doing something wrong. I would love for just five minutes to be a normal (正常的)person and not have all these things in my head."

    Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk (垃圾) has become a problem in outer space too.

    According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. Andtheseare just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.

    Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.

    To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

    To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

    Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

    "The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.

    "The time to act is now. The longer we leave the problem, the bigger it will become," he says.

Harbin is known as "the City of Ice". Usually, it has heavy snow from the early November. It's time for Harbin to come to life and attract visitors all over the world. 

Harbin Ice and Snow World has been a business card since 1999. This 816,682-square-meter park is the largest ice and snow theme park in the world. Visitors can enjoy more than 1,000 artworks made of ice and snow. And also, they can try the super ice slide (滑梯). The number of the ice slides this year is increased from 8 to 14 and the longest one is 512 meters. 

Visitors from the south of China is a large part of the tourism crowd. Chen Ling, a visitor, said, "I'm from Guangzhou. I come here to enjoy the hot winter. My trip will last about a week. I hope I will have a great time!" However, the southern visitors may be less prepared for the cold. So the local government gives the most important suggestion: Pack enough warm clothes. The more, the better. A Harbin taxi driver said, "My wife works in a hotel. These days we're busy but we both feel very excited. Ice and snow are important parts of our city. All the visitors are sure to feel the enthusiasm (热情) of us. Welcome to my hometown!"

You may feel bored in winter sometimes. But Harbin Ice and Snow World can make the long, cold months beautiful and creative.
