All living things on the earth need other living things to live with. Nothing lives 1 . Sometimes one living thing kills 2 . Each kind of life eats another kind of life 3 live, and together they form a food chain(食物链). Some food chains are simple, while others are not. But 4 food chains begin with the sun, and all food chains become 5 if one of the links disappears.
All life needs sunlight to live on. But only plants can use 6 directly(直接地). They make food from sunlight, water, air and so on. Animals can only use the sun’s energy 7 it has been changed into food by plants. Some animals feed directly on plants. Others eat smaller animals. Meat-eating animals are only 8 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 9 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 10 be eaten. If people eat the fish, they will get strange diseases.
Each form of life is linked to all the others. Breaking the links puts all life in danger.

Triathlon is a race in which each person swims, rides a bicycle and runs over very long distances. It has been held ten times in Hope Town. Sam, aged 20, finished nine races with his younger brother Luke. Every race was a victory for them. Luke can’t walk, talk or feed himself because of a rare brain illness since birth. But Sam wants his brother to know what it feels like to be part of a sport instead of having to sit and watch. A local TV journalist interviewed Sam after he received the Town Hero Award.
(J=Journalist, S=Sam)
J: How did you get the idea to include Luke in these events?
S: When I was ten, my mom showed me a video of two young men from another city doing triathlons. One of the men had a condition like Luke has. I got the idea from that.
J: What’s it like having Luke along?
S: I feel good and proud during the whole triathlon, for I’m giving something to Luke. He can experience things any other man would.
J: What do you get from him?
S: It’s the smile on Luke’s face. That smile brightens me. The feeling of knowing that I’ve done something for him is unbelievable.
J: When you received the Town Hero Award, you talked about the importance of changing the way you see things. What did you mean?
S: People see Luke very differently: “Oh, he can’t do something like that. He’s disabled.” But if you just change how you see things, you can see there are many possibilities where Luke can do swimming, biking or even triathlons, like we do.
