E-books are a relatively recent invention. They are popular for a great many of reasons. An e-reader takes up much less rooms in a suitcase: perfect for people who had to take several books on holiday. Besides, lots of people don’t reread books; an e-reader mean they don’t end up with a house filling with books they’ll never look at again. People say they’re more environmentally friendly: no trees cut down for paper, or no ink is needed. However successfully these devices are, nothing can beat an appeal of a genuine book for me. After all, if I’m short in cash, I can always go to the library and borrow books for free!

The oceans are unique to our planet. No other planet in our solar system has liquid water. The oceans cover about 70% of the earth's surface. They contain about 97% of the earth's water supply. Life on earth originated in the seas. The oceans continue to be home to an incredible number of plants and animals.

We know very little about the oceans. Because they are so deep and dark, they are hard to study. But scientists are discovering new strange creatures all the time. We are learning more by using satellites to look at the oceans' surfaces and by using buoys (航標(biāo)) to measure temperature and saltiness. Special vehicles can now travel deep into the dark oceans to see what mysteries can be discovered.

More of the sun's heat is assimilated by water along the equator than at the poles. This means the water at the equator is warmer than water at the poles. These different water temperatures cause the water in the oceans to move. This is called an ocean current.

The air above ocean currents also moves. The warm or cold ocean air moves over the land as wind. Oceans are also a really important part of the water cycle. Evaporation (蒸發(fā)) from oceans creates most of the world's rainfall. Plants on land need the rain to absorb nutrients from the soil.

The oceans are also home to all kinds of sea life. These include fish, whales, dolphins, octopi, lobsters, crabs and shrimps. There are also jellyfish and starfish. Many kinds of plants, such as plankton, kelp and sea grass are part of the "forest of the seafloor."

Carbon dioxide in-oxygen out! Oceans help to capture and store carbon dioxide(C02). They are the largest natural "carbon sinks" in the world. Oceans trap about 1/4 of the CO2 that humans put into the air. Oceans also release oxygen. Half of the world's oxygen is produced by these tiny plants!

1.What does the author think of oceans?

A. They are amazing. B. They are common.

C. They are boundless. D. They are unimaginable.

【小題2 To know more about the mysterious oceans, ________.

A. scientists use satellites in the oceans

B. scientists are discovering new strange creatures

C. scientists are using satellites to monitor the depth of oceans

D. scientists are introducing scientific equipment in the research

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

A. Taken in. B. Given off.

C. Cut down. D. Held back.

3.It can be inferred from the passage that ________.

A. oceans produce much carbon dioxide

B. it is not safe to live by the oceans

C. oceans provide humans with rich resources

D. humans can only depend on oceans for water

On May 18,1969,NASA astronauts Thomas Stafford,John Young,and Eugene Cernan boarded the Apollo 10 lunar module(登月艙)—the fourth manned mission in the US Apollo Space program and only the second after Apollo 8 to circle the moon.Its mission was to circle the moon and thoroughly test the components and procedures to pave the way for the first lunar landing. The mission went perfectly without incident—at least that’s what every one believed.

However, that view has changed since February 22, after NASA released a digital recording of strange music heard by the space travelers.Then as they were re-entering the zone where they could communicate with ground control.One of the astronauts asked if they should report it.In response, Stafford expressed his doubts if anyone would even believe them.But they needn’t have worried. When NASA experts listened to the recordings,they thought the strange sounds were radio interference.

Michael Collins—the Apollo 11 pilot—said that the only reason why he was not shocked upon hearing them was that he had been forewarned by NASA officials.Collins also said that the music stopped as soon as the lunar module landed on the moon.

So why did it take NASA over 40 years to release the digital recording of the awful music only after it was featured in a recent television series NASA’s Unexplained Files? The US Space Agency says they have not been hiding them.In the press release that accompanies the release of the recording,NASA officials state,“The Apollo 10 audio clips were uploaded in 2012, but the mission’s sound recordings have been available at the National Archives for anyone that wanted to hear them since the early 1970s.”

Eugene Cernan, Apollo 10’s pilot who heard the sounds first,also released a statement saying,“I don’t remember that incident excited me enough to take it seriously.It was probably just radio interference.Had we thought it was something other than that,we would have briefed everyone after the flight. We never gave it another thought.”

While most people are ready to accept this logical explanation,there are some that believe otherwise. They guess the music proves the presence of aliens. Among them is Apollo 15 astronaut Al Worden,who thinks the sounds came from a source in outer space.In the episode of NASA’s Unexplained Files, which discusses the origin of the strange music,the astronaut says, “Logic tells me that if there was something recorded on there,then there was something there.”

1.Apollo 10’s mission was to ________.

A.take the astronauts to the moon

B.detect alien music in outer space

C.prepare for the landing on the moon

D.move around and observe the moon

2.When the astronauts heard the sounds, ________.

A.they were excited about the discovery

B.they reported to NASA

C.they were heading back to the lunar ground

D.they thought they might be of little importance

3.According to the passage, ________.

A.the mission of Apollo 10 turned out to be unsuccessful

B.NASA made the TV series to clarify some space-related mysteries

C.Al Worden on Apollo 15 believes in aliens and logic

D.Michael Collins knew about the strange sounds before his flight

4.What is the main idea of this passage?

A.A TV program was released about NASA’s unexplained files.

B.The music heard by Apollo astronauts could be radio interference.

C.NASA releases strange music heard by 1969 astronauts.

D.Apollo astronauts heard strange sounds from outer space.

I had worried myself sick over Simon’s mother coming to see me. I was a new teacher, and I gave an honest account of the students’ work. In Simon’s case, the grades were awfully low. He couldn’t read his own handwriting. But he was a bright student. He discussed adult subjects with nearly adult comprehension. His work in no way reflected his abilities.

So when Simon’s mother entered the room, my palms (手掌心) were sweating. I was completely unprepared for her kisses on both my cheeks. “I came to thank you,” she said, surprising me beyond speech. Because of me, Simon had become a different person. He talked of how he loved me, he had begun to make friends, and for the first time in his twelve years, he had recently spent an afternoon at a friend’s house. She wanted to tell me how grateful she was for the self-respect I had developed in her son. She kissed me again and left.

I sat, stunned, for about half an hour, wondering what had just happened. How did I make such a life-changing difference to that boy without even knowing it? What I finally came to remember was one day, several months before, when some students were giving reports in the front of the class, Jeanne spoke quietly, and to encourage her to raise her voice, I had said, “Speak up. Simon is the expert on this. He is the only one you have to convince, and he can’t hear you in the back of the room.” That was it. From that day on, Simon had sat up straighter, paid more attention, smiled more, and became happy. And it was all because he happened to be the last kid in the last row. The boy who most needed praise was the one who took the last seat that day.

It taught me the most valuable lesson over the years of my teaching career, and I’m thankful that it came early and positively. A small kindness can indeed make a difference.

1.We can infer that when Simon’s mother entered the room, the writer felt _______.

A. satisfied B. nervous

C. happy D. surprised

2.Why did Simon’s mother come to visit her son’s teacher?

A. Because she worried about her son’s poor work.

B. Because she wanted to show her gratitude to the teacher.

C. Because Simon asked her to do so.

D. Because she wanted to know her son’s performance in the school.

3.What the teacher said in paragraph 3 is intended to _______.

A. encourage Jeanne to speak louder

B. encourage Simon to work hard

C. ask Jeanne to convince Simon

D. tell the students that Simon was expert on that.

4.The purpose of the passage is to ________.

A. tell the story of Simon

B. tell teachers how to be kind to students

C. advise the readers to be kind to others.

D. share a valuable lesson with readers.
