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(存储) 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?

3.How do hummingbirds eat?

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?

Two men walked slowly, one after the other. All they could see were stones and earth. They had bags on their backs, but no food. They had guns, but no bullets.

Suddenly the man who followed fell over a stone. He hurt his foot badly and cried: "Bill. I've hurt my foot. Help me! "Bill continued straight on without looking back.

The man was alone in the empty land. His foot hurt, but it was nothing compared with his hunger. He had not eaten for many days and could hardly move his feet. Bill would be going to find the right way for them, he thought. He crawled about, on hands and knees: As he moved on, the bag became heavier and heavier. He opened the bag, which was full of small pieces of gold. He left the gold on a stone. In the evening, he built a fire and slept like a dead man.

Eleven days passed, days of rain and cold. One morning, he woke up and heard a noise behind him. Wolf, old and sick, was coming slowly toward him. He rose to his feet and moved forward, knowing well the sick wolf was following him. Later, he found some bones . Beside the bones was a small bag of gold, like his own. So Bill had carried his gold to the end. He looked at the bones. Would he, too, be bones tomorrow? And why not? This was life. Then why was he not ready to die? It was the life in him, unwilling to die, that drove him on.

The man had lost everything-his gun, and his gold. Only the wolf accompanied him. At last he could go on no further. He fell. The wolf came close to him, but the man was ready. He got on top of the wolf and held its mouth closed. Then he bit it with his last strength . He held the wolf with his teeth and killed it, and then he fell on his back and fell asleep.

Later that day, the people on a ship saw something strange lying on the beach. It was moving toward them very slowly-perhaps twenty feet an hour. They took a careful look and could hardly believe their eyes-it was a man!

1.When the man cried for help, Bill continued straight on because

A.he didn't hear the man's words B.he didn't want to help the man

C.he saw a sick wolf coming to them D.he went to find the right way for them

2.What does the underlined word "accompany" probably mean in the passage?

A.Stay with B.Fight with.. C.Care for D.Worry about.

3.What can you infer from the passage?

A.Bill stole some gold from the man on the way

B.The man found some bones of a wolf in the land

C.The bag became heavier because the man got weaker

D.The people searched for the man and finally found him.

4.What do you think of the man in the passage?(请用约40词回答)
