When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight off enemies.
Over millions of years, plants have developed their own defense system (防衛系統). Chemicals are fantastically used by plants to survive (幸存). By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.
One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount (數量) of poison increases in the other leaves. “It’s like the injured leaves telephoning the others to fight together against the enemy,” he said.
The tree also sends defense messages to neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, he will die.
Every kind of plant or tree is good at producing a special set of chemicals. Herbivores, like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor.
In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest.
小題1:From the first 2 paragraphs, we can learn that _________.
A.plants can do nothing against their enemies
B.chemicals are quite useful for plants to survive
C.an antelope can always run away from a strong lion
D.leaves, roots, flowers and fruits of plants are poisonous
小題2:If animals eat one Golden Wattle tree’s leaves, the tree can________.
A.kill the animals with a special smell
B.tell other trees to come to protect it
C.warn other trees against the animals on the phone
D.send defense messages to the neighboring plants
小題3:The underlined word “herbivores” in the 5th paragraph probably means animals which _____.
A.produce poisonB.live on small animals
C.like to eat rabbitsD.feed on plants or grass
小題4:The last paragraph of the passage suggests that this kind of defense system is ________.
A.bad for animals B.good for forests
C.helpful to some animalsD.harmful to forests
小題5:The passage is mainly about __________.
A.the examples of protecting forests
B.the balance between animals and plants
C.the ways of plants fighting against enemies
D.the relationship between lions and antelopes

Now satellites are helping to forecast(預報)the weather.  They are in space, and they can reach any part of the world.  The satellites take pictures of the atmosphere(大氣), because this is where the weather forms(形成).  They send these pictures to the weather stations.  So meteorologists(氣象學家)can see the weather of any part of the world.  From the pictures, the scientists can often say how the weather will change.   Today, nearly five hundred weather stations in sixty countries receive satellite pictures.  When they receive new pictures, the meteorologists compare(比較)them with earlier ones.  Perhaps they may find that the clouds have changed during the last few hours.  This may mean that the weather on the ground may soon change, too.  In their next weather forecast, the meteorologists can say this.
  So the weather satellites are a great help to the meteorologists.  Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours.  Now they can make good forecasts for three or five days.  Soon, perhaps, they may be able to forecast the weather for a week or more ahead(提前).
小題1:Satellites travel _____________.
A.in spaceB.in the atmosphereC.above the groundD.above space
小題2:Why do we use the weather satellites to take pictures of the atmosphere? Because __________.
A.the weather satellites can do it easily
B.clouds form there
C.the weather forms there
D.the pictures can forecast the weather
小題3:Meteorologists forecast the weather __________.
A.when they have received satellite pictures
B.after they have compared new satellite pictures with earlier ones
C.before they received satellite pictures
D.during they study satellite pictures
小題4:Maybe we’ll soon be able to forecast the weather for ________.
A.one dayB.two daysC.five daysD.seven days or even longer
小題5:The main(主要的)idea of this passage is that satellites are now used in _________.
A.taking pictures of the atmosphere
B.receiving pictures of the atmosphere
C.doing other work in many ways
D.weather forecasting

In nature, you may see many insects (昆蟲)and animals of different colors. Have you ever wondered why?
Locusts are super delicious food for birds,but it is not always an easy job for birds to catch them.It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(莊稼). When crops are young,locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.
Brown bears,tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil(土壤) in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive,they have to hide themselves in the daytime and appear only at night.
Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.
小題1:It is not easy for birds to catch locusts because____________.
A.locusts are good runnersB.locusts can jump very high
C.locusts are smarter than birdsD.locusts can change their color

Arthur sat at the desk in his room, pencil in hand. He had to write a story for his English class by Friday. “I don’t know what to write about,” he complained to his dog Toby, who was asleep at his feet. Arthur was talkative when speaking to his friends, yet he had trouble finding words when he had to write.
By bedtime Arthur had drawn a picture of Toby smiling. He had drawn a tree with its branches blowing in the strong wind. He had also written a note asking his friend Lee to go to the movies on Saturday. But he had not written a single word of his story.
On Wednesday, Mrs. Solomon, Arthur’s English teacher, asked the class to turn in the first draft of their stories. His heart sinking, Arthur turned in the only work he had—the page with his name, the drawings and the note.
Arthur wasn’t surprised when Mrs. Solomon asked him to stay after class the next day. But he was surprised by what she said to him. “This is an attractive story, Arthur. The dog, the movie, the tree in the wind—I can’t wait to find out how they all fit together.”
“That isn’t my story, Mrs. Solomon,” Arthur admitted. “I haven’t been able to think of one yet.”
“Oh, I think you have the seed(種子of a story there,” Mrs. Solomon replied, “Look at your note and the pictures and see if a story comes to you.”
That night Arthur sat at his desk, and this is what he wrote: “One Saturday Mike went downstairs to meet his friend Julio at the cinema. It looked as if it might rain, so Mike carried his umbrella. Suddenly a big storm blew in, bending the trees. The noise of the wind sounded like the barking of Mike’s dog Toby. Toby really hated storms and barked whenever he wanted to be let inside. Then Mike realized that it wasn’t the sound of the wind. It was Toby. The dog was running after him down the busy street, barking. The sound was filled with blame. Mike felt guilty because he had left Toby outside. He turned and headed home with Toby running beside him. Mike let Toby in the door just as the rain started to pour down.”
Arthur had a story in the end. The last thing he did was to write his name proudly at the top of the page.
小題1:Why did Arthur turn in the page with only his name, the drawings and the note at first?
A.Because he had no time to fit them together.
B.Because he had difficulty in writing a story.
C.Because he wasn’t willing to do his homework.
D.Because he wanted to show his talent for drawing.
小題2:What does the underlined sentence in Paragraph 6 probably mean?
A.Toby is an imaginative and lovely dog.
B.The small tree will grow into a big one.
C.His friend Lee can give him a lot of support.
D.He can develop his story based on the first draft.
小題3:What kind of teacher do you think Mrs. Solomon is ?
A.She is a strict teacherB.She is a wise teacher
C.She is an honest teacherD.She is an energetic teacher
小題4:What can we infer(推斷from the story?
A.Arthur is a shy and quiet student
B.Arthur isn’t very satisfied with his story
C.There will be a storm on Saturday
D.Encouragement is important in teaching

Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻擊) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨頭). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attack attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.
小題1:What happens to people attacked by sharks?
A.Most of them because blind.B.Most of them because of deaf.
C.Most of them died.D.Most of them are still alive.
小題2:How do sharks find out about an unusual object according to the passage?
A.By biting.B.By smelling.
C.By touching.D.By killing.
小題3:Which sentence about sharks is true?
A.Sharks pull meat off bones when they eat.
B.Sharks might mistake humans for seals.
C.Sharks like to attack surfers because of their thick fat.
D.One bite from a shark is nothing serious.
小題4:What would the author write the passage mainly for?
A.To tell surfers to stay away from sharks.
B.To ask people to stop killing sharks.
C.To let us know the reasons for shark attacks on people.
D.To show that humans are much stronger than sharks.
