The Garbage (垃圾) Project started at the University of Arizona in 1973. Since then, the students and teachers in it have studied the modern garbage in different cities.

To study the garbage, the students had to travel to landfills (填埋場(chǎng)) , the places where cities bury (填埋) their garbage. While the students were studying the garbage they wore special clothes. Students were very careful when they opened bags of garbage.

One important thing the students have learned from studying the garbage is that the garbage in landfills disappears very slowly. That was surprising to both the students and many scientists who had thought that about 70 % of the garbage in landfills would disappear quickly. Even in cities where it rains a lot, the students found newspapers from 1948, 40-year-old hot dogs, and vegetables from 1970. And the students also found many more empty bottles of cola than they expected.

How to dispose of our garbage well depends on what kind of garbage it is: regular(普通的) garbage, dangerous materials, or recyclable materials, such as newspapers and glass bottles. Regular garbage goes to regular landfills. Dangerous materials are harmful to people's health and the environment. They shouldn't go into regular landfills.

Homes are full of dangerous waste. One kind of the dangerous waste in homes is batteries. When batteries are buried directly（直接地）in a landfill, they often break open. The poison inside them moves through rain water to the bottom of the landfill. Then it can pollute the natural water in the ground.

Another dangerous waste from homes is motor oil. When people pour old motor oil on the ground or throw it in the garbage, it pollutes the environment.

Our garbage problem is not new, but as the world's population continues to grow, it will become a bigger and bigger problem.

Read the passage and choose the best answer.

Have you ever heard the sound of a hummingbird? They make a buzzing noise when they fly. They make this noise because they beat their wings so fast. They beat their wings up to 80 times a second. All that flapping makes a lot of noise. That’s why we call them hummingbirds.

Hummingbirds fly in a unique way. They move their wings so fast that they can hover. This means that they can stay in one spot in the middle of the air, like a helicopter. Sometimes they fly or hover upside down. They are the only bird that flies backward.

Hummingbirds are small. One type called the bee hummingbird is the smallest bird in the world. Bee hummingbirds weigh less than a penny. They are just a little bit bigger than bees. I guess that’s where they get their name.

Hummingbirds move fast. It takes lots of energy to move as fast as they do. This means that they need to eat a lot of food. Their favorite food is nectar, a sweet liquid inside of some flowers. They drink more than their own weight in nectar daily. They have to visit hundreds of flowers to get enough nectar to live. They can only store(存儲(chǔ)) enough energy to survive through the night. They live on the edge. Hummingbirds don’t use their long beaks like straws(吸管). They have a tongue just like you. They use their tongues for eating. They flick their tongues in and out of their mouths while inside of lowers. They lap up nectar. Flowers give them the energy that they need.

Hummingbirds help flowers too. They get pollen(花粉) on their heads and bills when they feed. Flowers use pollen to make seeds. Hummingbirds help pollen get from one flower to the next. This helps flowers make more seeds. More seeds means more flowers. More flowers means more food for hummingbirds. Isn’t it nice how that works out?

1.Why are they called hummingbirds?

A.They are very light. B.They sing when they fly.

C.Their wings make a humming sound. D.Their song sounds like humming.

2.Which best defines the underlined word (second paragraph) “hover” as used in Paragraph Two?

A.To stay in one spot in the air. B.To clean an area thoroughly(徹底地).

C.An animal that has hooves. D.To move your wings very fast.

3.How do hummingbirds eat?

A.They drink nectar through their beaks like a straw.

B.They chew up flower petals(花瓣) with their beaks.

C.They use their heads and bills to eat pollen.

D.They lap up nectar with their tongues.

4.How do hummingbirds help flowers?

A.They drink nectar. B.They eat pollen.

C.They bring pollen from one flower to the next. D.They plant seeds.

5.Which title best describes the main idea of this text?

A.Bee Hummingbirds: The World’s Smallest Bird B.Pollination: How Birds and Flowers Work Together
