One type of fish is named salmon(大马哈鱼). There are many different kinds of salmon, but almost all of them mate(交配) in a very strange way. They are born in small, freshwater rivers. They live in the river for a year, and then swim downstream to a bigger river and eventually to the ocean very quickly. While they live in the ocean, salmon are silver coloured.

After several years at sea, the salmon grow very long and heavy. Then, as if by magic, they all begin to swim home. Each salmon somehow remembers where it was born and the very same area in the small river.

It is a long, difficult journey home. Once the salmon enter fresh, they stop eating. They also change colours. Some salmon turn red, other brown and grey, and some turn pink. Some salmon grow a large bulge on their back, called a hump. These salmon fight to swim upstream against the current of sometimes very to avoid bears, birds, and fishermen

Finally, the salmon that survive mate in the same river in which they were born. Then, after all that work, they die! These salmon still play an important role. Their dead bodies help to provide nutrition(营养) to the animals that live in and around the river When their eggs hatch, the cycle will start again.

1.Which of the following do salmon NOT do when they reenter fresh water?

A. They change colours.

B. They stop eating.

D. They grow teeth.

A man was walking on a mountain when he found an amazing cave. Stored inside were all kinds of treasure and precious stones. When he saw it, he concealed the cave entrance and stayed there, guarding it.

From that day on, the man hid all his valuables in the cave, and to avoid anyone suspecting he was rich, he gave up his job, his home, and his friends. He constantly watched the approaches to his cave, wanting no one to find out about it. Fearing thieves, he guarded the cave all night long.

He was so devoted to the cave that he hardly ate or drank. Before long, he fell ill. Many days passed, and he got thinner and sicker, losing all his strength. One day, when he could hardly move at all, he realized that it was his greed that had brought him to this extreme end. He understood that guarding his treasure had been of no use and no good. He decided to share it with others.

He crawled (爬) into the cave to fetch some jewels, but discovered that the cave was almost empty. All he could find was a small emerald (绿宝石). He took it and left the cave, intending to give it to the first person passing by. Soon a woman approached and accepted the emerald with great joy. The man said to her, “I could have given you many more riches, but I don’t know where they went. This is all I have now.”

“Are you sure there’s nothing else?” replied the woman. The man shook his head and pointed to the cave. He found that some riches were still there; he saw some gold coins. He said, “Take them with you.” The woman took both the emerald and the coins, and went away happily.

In a while, an old man passed by and asked the man what he was doing there. The man replied, “What bad luck! Just a moment ago I gave a woman the few riches left over from the treasure I was guarding.”

“Are you sure there’s nothing else?” The old man asked him.

The man showed him the cave, and they found a box filled with jewels and gold. The man was shocked. The old man explained to him, “At last! At last someone has freed himself from the spell (咒语) of this cave. You see, this is a magic cave, and you’re the first to pass its great test. Many people have devoted their lives to this cave, only to end up realizing there’s nothing here ...”

“And why does this happen?” said the man. “Why does the treasure appear and disappear?”

“My son, this magic cave has as many riches as does your own heart. When someone discovers it, the cave fills with the treasure they bring with them, but later, when they all devote themselves to guarding the treasure, their hearts begin emptying, and so does the cave. The only way to fill it is to fill your heart with all that is good, as you did by giving that last jewel to the woman. That’s the reason why the cave was filling up again ...”

And so, the man understood it was better to share than to keep things to himself. And, from that day, thanks to the cave and the old man, the man became ever more noble (高尚的) and generous.

1.The underlined word “concealed” in the first paragraph can be replaced by “_____”.

A. built　　　　　　 B. covered

C. discovered　　　　 D. used

2.After the man fell ill, he intended to ______.

A. tell others about his story

B. take all the treasure home

C. give some of the treasure to other people

D. return the treasure to the woman and the old man

3.What happened to the man in the end?

A. He became more generous.

B. He became the richest man in the world.

C. He became more careful about his health.

D. He became more grateful to others for their help.

4.What can we learn from this passage?

A. Be a good listener.

B. Don’t be angry with others.

C. We should learn to share.

D. We ought to help each other.

高二英语单项填空简单题查看答案及解析

Even if trees cannot walk, they are still on the move.

In parts of the Arctic, entire forests are moving northward. Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra （冻土地带）starts has been shifting northward. Trees growing along the tree line must protect themselves from the cold wind. To do this, plants tend to grow horizontal （水平的）branches low to the ground. The energy it takes for trees to grow this way means they don't have enough energy to make seeds.

But as Earth's climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. And with all the leftover energy. these trees have started producing more seeds. This happens especially in places where the white spruce （白云杉）grows.

White spruce, which is a North American tree, is quite able to produce a lot of seeds, which can move long distances in the wind. When wind-blown seeds end up on the tundra beyond the tree line, they eventually can sprout （发芽） new trees. This explains how a forest can move. Of course, the process would work only if the tundra were warm enough. But in recent years, the whole planet has been warming.

New trees will provide shelters for some snow, keeping the sun’s rays from making the white surface disappear. Instead, the trees absorb the sun's heat. This warms the surrounding air. The extra warmth encourages even more trees to produce seeds. That further boosts a forest's ability to expand. In addition, more trees will trap more snow, preventing much of it from being blown away. Snow can trap heat in the soil below,which encourages trees to grow. The recent rise of temperature has helped more trees grow.　 The recent rise of temperatures has helped more trees grow past the tree line. People worry about impacts on the animals that depend on frozen conditions for food and shelter.

1.What is the main cause of the trees in the Arctic moving northward?

A. The rising temperature.

B. The shrinking of northern tundra.

C. The fierce and cold wind.

D. The abundant resources in the north.

2.What does the underlined word, “this”, in Paragraph 2 mean?

A. To produce more seeds.

B. To move northward

C. To respond to the climate change.

D. To protect themselves from the cold wind.

3.What can be inferred from the last paragraph?

A. New trees can trap the snow, which may make the soil colder.

B. The trapped snow prevents new trees from producing more seeds.

C. New trees can make the surrounding air warmer.

D. New trees can bring more food and shelter for local animals.

4.The passage is most probably taken from _______.

A. a health report　　　　　　　　　　　　 B. a science report

C. a fashion magazine　　　　　　　　　　 D. a children's magazine
