You’re on the school bus. But as soon as you turn the corner, you find yourself at the end of a very long queue. It’s another traffic jam! It is stop-start for the rest of your journey. Meanwhile, at the same time in Antarctica(南極洲), snow covers the land. A group of emperor penguins crowd together to keep warm, using stop-and-go movements to protect themselves from the winds. Can you see the connection?
Emperor penguins move like cars in traffic jams to keep warm, that’s according to new research by the Alfred Wegener Institute, Helmholtz Center for Polar and Marina Research in Germany. A penguin only needs to move 2cm in any direction for its neighbor to do the same thing. These movements then flow(流動) through the whole group of penguins like a “traveling wave”.
These waves also help smaller crowds join bigger groups, keeping more and more of their friends warm. A single Antarctic “traffic jam” has thousands of penguins. Interestingly, the technology used for studying road traffic jams was used to study the penguins. This included studying time-lapse(延時) videos. Scientists also discovered that unlike on the road, these waves can be made by any penguin and in any direction.
With temperatures usually dropping below –50℃, and winds reaching speeds of up to 200km/h, these traveling waves are very important for penguins to keep warm.
These penguins can also teach us a lesson. In big groups, they learn to be orderly and patient, and to never crash into each other. These are skills we should all learn from them when we are on the road!
小題1:Emperor penguins get together to _____.
A.keep warmB.play gamesC.learn from each otherD.cross the road
小題2:In a traffic jam on the road, __________.
A.drivers can drive fastB.drivers can drive carelessly

小題3:From the passage, we learn that a “traveling wave” _____.
A.is caused by a traffic jam on the road
B.is caused by the strong wind in Antarctica
C.is formed by the movement of the penguins
D.is made by just one or two penguins
小題4:If a penguin is in a group, it _____.
A.needs to move orderlyB.can move as fast as it likes
C.will not leave others behindD.should move as slowly as it can
小題5:The last paragraph wants to tell us that _____.
A.penguins won’t move together if it is not very cold
B.traffic jams happen probably because people are impatient
C.penguins learn their skills from human beings
D.penguins are likely to crash into each other in a group

People often said Thomas Edison was the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be pleased only because someone said he was a genius. “There is no such a thing as genius,” Edison said. He thought what people called genius was mostly hard work.
But Edison was a thinker as well as a worker. From his earliest days as a child he wondered about the secrets of nature. He tried to understand them, and then he tried to learn what he could usefully do with them.
Edison enjoyed thinking. He knew that most people would do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking could give men enjoyment and pleasure.
Edison could not understand why anyone could not be interested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what idea he had about life. “Work,” he answered, “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.
小題1:What is genius according to Thomas Edison?
A.Hard thinking. B.Hard work.C.Useful ideas.D.Useful inventions.
小題2:How did Edison always deal with the secrets of nature after exploring them?
A.To write down what he had learned.
B.To carry out a new experiment.
C.To make them useful in life.
D.To share them with others.
小題3:What does the last sentence in the passage mean?
A.Edison was born to be a great inventor.
B.Edison was able to live another 100 years.
C.Edison was ready to make his 100th invention.
D.Life was too short for Edison to work for human beings.

根據短文內容,按要求答題。
Every Saturday, Grandpa and I walk to the nursing home to visit some of the old and sick people there because they can’t take care of themselves.   First we visit Mrs. Sokol. I call her “The Cook.” She likes to talk about the time when she was a well-known cook in Russia. People would come from miles, just to taste her chicken soup. Next we visit Mr. Lipman. I call him “The Singer” because he loves to sing for us. Whenever he does, his voice fills the air, clear and full of energy. I also enjoy Mrs. Kagan’s stories about her own experiences during the old days. I call her “The Memory Lady.”
One day Grandpa got very sick and the doctor said they didn’t think he would get better.
It was time to visit the nursing home again. I had to go alone. Everyone was surprised when I told them that my grandpa was ill and in hospital.
A few days later, Grandpa was not able to sit up, eat and even speak. I went to the corner of the room so Grandpa wouldn’t see me cry. Suddenly, I heard someone singing. I looked up. It was The Singer. Behind her were The Cook. and The Memory Lady. The Cook brought her famous homemade chicken soup. The Memory Lady held Grandpa’s hand and told us how Grandpa once came to visit her in a snowstorm, just to bring her some roses for her birthday.
Before I realized it, visiting hours were up. That evening, Grandpa called the nurse in and said he was hungry. Soon he began to sit up. Finally he was able to get out of bed. It is really a miracle (surprising event), isn’t it?
小題1:Why did the writer and his grandpa go to the nursing home every Saturday?
