All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they form a food chain(食物链).Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links disappears.
All life needs sunlight to live on. But only plants can use sunlight directly. Plants are“factories”.They make food from sunlight, water and things in the soil and air.
Plants feed all other living things. Animals can only use the sun’s energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.
What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruits and so on. We also eat meat and drink milk. But men often break up the food chains. They kill wild animals. They also make rivers, lakes and seas dirty. When these rivers, lakes and seas are polluted, the fish in them cannot be eaten. If men eat the fish, they will get strange diseases.
Each form of life is linked to all others. Breaking the links puts all life in danger.

I do not need a calendar to tell me when it is winter. All I need is my nose. When I wake up in the morning and smell the tasty treats my mom is cooking downstairs, I know winter has arrived.
The first one is the smell of chocolate. During the holiday season (from Thanksgiving to New Year’s Day) my mother makes her special hot chocolate. She always adds a peppermint candy cane (薄荷味拐棍糖) to the drink and tops it with cream.
The hot chocolate gets me out of bed, but it is my mother’s chocolate fudge (软糕) that makes me run downstairs. It is a thick chunk (块) of chocolate that tastes like heaven. My mother adds nuts. That gives it more texture (质感).
But my mother isn’t done yet. She also makes a treat she calls “window panes (窗玻璃)”. She takes a few different colored marshmallows (棉花糖) and melts them together with chocolate. The final product looks like a colorful church window, so we call it “window panes”.
These tasty holiday treats are usually eaten after a meal as a dessert. But don’t tell Santa Claus because I secretly eat them all day long.

A teenage girl couldn’t stand（忍受）her family rules, so she left home.

One day, the daughter saw one of the photos. She was so surprised that she couldn’t believe her    44  . “Is that me?” She moved    45   and read the words, “I still love you…” She cried. She couldn’t wait    ___46   back home. When she got home, it was early morning. She pushed the door. The door opened itself. She rushed to the bedroom at once. Her mother was sleeping there. She    47   her mother up, “It’s me! Your daughter is back home!” The mother and daughter looked at each other with excitement, full of happy tears. The daughter asked, “   48  is the door unlocked? A thief could get in.” The mother answered softly, “The door has never locked    49   you left. We miss you all the time. We believe that you’ll come back some day.”
As everyone knows, parents love their children forever. Children should also understand their parents and share their happiness, sadness, even everything with their parents.    50   this way, both parents and children can be happy.
