閱讀下列短文，從每題所給的四個選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。

Scientists recently found three animal species living two miles below the surface of the Mediterranean Sea, where the super-salty waters don’t have oxygen(氧). They’re multicellular(多細(xì)胞的), which means their bodies have many cells. They each are as small as a large grain of sand. But they are animals.

The most exciting thing about these creatures, say the scientists, is that they obviously don’t need oxygen to live. What biologists know about life so far is that only single-celled living things can live in places that have no oxygen, and that multicellular organisms(有機(jī)物) can visit these places, but not live there. These newly found creatures could change that idea.

Finding animals down there was so surprising that the scientists couldn’t believe it. At first, “we thought they were dead bodies,” Roberto Danovaro, a scientist at the Polytechnic University of Marche in Ancona, Italy, told Science News. To find out whether the animals could actually live there Danovaro and his colleagues brought up more samples(樣本) from the ocean floor. Studying the animals in the new samples showed that they appeared to be alive.

The researchers did more tests, and found that some of the animals had eggs—which suggests they were reproducing(繁殖). Also in the samples were old skins, suggesting that the animals had lived there long enough to grow. Finally, pictures taken showed that the insides of the animals appear to be adapted to live in an environment that has no oxygen.

These clues suggest the animals don’t need oxygen, but the evidence(證據(jù)) is indirect, which means that scientists still have not observed how the animals live without oxygen. This means more studies are needed, but the scientists think they’re on the right track. And if they’re right, biologists will need to rethink what they know about where animals live.

1.What excited the scientists most is that ______.

A.they found three animal species visit the salty water under the Mediterranean Sea

B.single-celled animals can live in super-salty waters

C.the tiny animals have many cells

D.three kinds of animals can live in places that have no oxygen

2.The underlined phrase in Paragraph 2 means the scientists could think _____.

A.only single-celled creatures don’t need oxygen to live

B.multicellular animals can visit the super-salty waters

C.the newly found creatures can’t live in the super-salty waters

D.multicellular animals also can live without oxygen besides single-celled ones

3.Which of the following CAN’T be used to prove the newly found creatures can live in super-salty waters?

A.Their dead bodies are found there.

B.Some in the samples have eggs.

C.Some old skins are found in the samples.

D.The pictures of their insides have been taken.

4.More studies are needed to prove_____.

A.where single-celled animals can live

B.how the newly found animals live without oxygen

C.whether the multicellular creatures can live underwater

D.why the super-salty waters have no oxygen

Tina Rees, 50

English teacher (Canadian)

I wanted to be a doctor and help people. I was always playing doctor with dolls, wrapping their arms and legs in tissues! My mom was a nurse, and my two sisters are now nurses, but I went into finance. The educational requirements to be a doctor are too much for me now, but I feel I'm helping people and contributing to society as a teacher.

John Podeszwa, 45

English school owner (American)

I've always loved animals, and as a little boy I first wanted to be a frog, then a chimp. When told I had to be something human, I chose zookeeper.

As a little girl I wanted to be many things, and when my grandmother suggested that as an actress I could play various roles, that stuck with me. The Takarazuka Revue (寶冢歌劇團(tuán)) was popular during my childhood, so that also inspired me. Of course I would still like to become an actress.

Hiromitsu Tokunaga, 55

Sewage worker (Japanese)

My dream job both as a child and now is to be an astronaut. I grew up during the “Space Race” era and remember well the first moon landing, the famous sci?fi movie 2001, and all the rest.

Years ago I moved to Woodland Hills to take a job in a small hospital’s emergency department. No one wanted to work on Christmas Eve, so the shift（輪班）went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.

At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.

The following year I got Christmas Eve duty again. At 9 pm sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr. Lee and said, “You probably don’t remember me, but last Christmas Eve you saved my life. Thank you for the year you gave me.” He and his wife hugged me, handed me a small gift, and left.

The following year a new doctor had joined the group, but I wanted to see if Mr. and Mrs. Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild. Mr. Lee, his family and I spent 13 Christmas Eves together.

The last year I saw him, he brought me a gift. I carefully opened the package and found a crystal bell inside. It was carved with a single word: Friendship. Now, my family, friends and I ring that bell every Christmas Eve at exactly 9 pm and offer our best wishes to the man who we won’t forget.

1.The author had to work the night shift on Christmas Eve probably because ______.

A. she was a new arrival

B. she was more experienced

C. her colleagues had no passion for working

D. her colleagues wanted to give her a surprise

2. When the author left the hospital the next morning, ______.

A. Mr. Lee’s heart sank

B. Mr. Lee insisted on leaving hospital

C. Mr. Lee got very angry with her

D. Mr. Lee was out of immediate danger

3.What does the author ring the bell every Christmas Eve for

A. To honor an old friend of hers.

B. To offer best wishes to her family and friends.

C. To show off her special gift.

D. To fill her family and friends with hopes.

閱讀理解。

For my grandmother’s 70th birthday，my family and I visited South Korea.While there，I was attentive to Korean high schools and students.

I was surprised by how different Korea’s public high schools are from America’s.Korean high schools can be all?girls，all?boys or co?ed (男女同校的) unlike our standard co?ed high schools.There are three grades：“go 1(10th)”，“go 2(11th)” and “go 3(12th)”．“Go” is the first syllable of the word “go?deung?hakkyo”，which，simply translated，is “high school”．

In America，unless you want to go to a private school，you don’t have to take an entrance exam.In Korea，however，students must take a test to get in because of the many choices of schools.

Another difference I couldn’t help but notice was the students’ appearance.With very few exceptions，all wear uniforms. A name tag (標(biāo)牌) with the student’s name，grade and homeroom number must also be worn.Girl’s skirts can’t be above the upper part of the knee，and it is forbidden to dye(染) your hair or wear accessories (裝飾品) except small earrings.There are strict regulations for appearance to achieve neatness，and it seems the only freedom students have is with their choices of hair style，socks and shoes.

The final difference was the setup of the classes.There may be 40 students in a classroom，but the number can be less or even more，depending on the population of the town or city.Although there are many students per classroom，they are very close，which I think is a result of not changing classrooms for different subjects.There are no levels in the subjects and the teachers are the ones who switch classrooms.They just have ten?minute breaks between subjects.In each class，students are ranked by their grades.This causes strict competition，and Korean students do a lot of studying.To help them，all schools have extra study classes after school.One other fact that helped me appreciate living in America is that Koreans have school on Saturdays.Although it’s only a half day，I think I speak for most Americans when I say we could never imagine ourselves in school on a Saturday.

Korea’s public high schools are clearly different from America’s.I had imagined them to be just like our schools，but now I have a clear picture of how different they are.

1.How many main differences are mentioned between Korea’s public high school and America’s?

A．3. B．4.

C．5. D．6.

2.It seems that the writer ________.

A．is familiar with the education system of high schools in Korea

B．is fond of Korean students’ appearance

C．prefers the high school life of America to the one of Korea

D．feels it common to have lessons on weekends

3.What does the underlined word “setup” in paragraph 5 probably mean?

A．Arrangement. B．Size.

C．Number. D．Outline.

4.According to the rules, the students of Korea can ________.

A．go to different high schools without exams

B．wear any clothes except uniforms at school

C．a(chǎn)ttend different classes as they like

D．have different hair styles

Complete the following sentence：“You go to the library to check out ...？” The obvious answer is “books”.But a harder question might be, “What do we mean by ‘books’？” Nowadays, electronic books, or “e?books”， have become more and more popular in American society.

The biggest online bookseller Amazon, for example, recently announced that less than four years after introducing them to its catalog, it is now selling more electronic versions of its book titles than printed ones.

Last week, Pew Internet Project released a survey about the use of e?books by library customers.It found that 12% of Americans aged 16 and older who read e?books say they had borrowed at least one from a library within the past year.But the survey found that the broader public, including 58% of those who have library cards and 53% of people who own electronic book readers, are not aware that they can find and check out e?books from public libraries, even though three quarters of the libraries offer that service.

Pew Internet Project director Lee Rainie noted that e?book borrowing is becoming more popular at the same time that publishers, who are selling plenty of e?books and fewer hard?copy editions, are worried that free e?book check?outs at the library will hurt sales.In February, for example, the big publisher Penguin Books stopped supplying new e?books and audio books to libraries.Penguin just reached an agreement to resume supplying one big library system in New York City but not until six months after new titles are released.That way, those who want the latest books will have to buy them.

So things are a little murky (陰暗的) in the library world when it comes to electronic books.More and more customers want them, but publishers are giving the libraries a hard time about offering them.Demand is not the problem.Supply may soon be.

1.What is the function of the two questions in the first paragraph?

A. To introduce the topic of the passage.

B. To stress the popularity of e?books.

C. To show what the author cares about.

D. To remind us of the change at the library.

2.According to Paragraph 2, what can we know about Amazon?

A. It has sold e?books for five years.

B. Its e?books are cheaper than printed books.

C. It has the best e?books among all libraries.

D. Its e?books sell better than printed books.

3.We know from the survey done by Pew Internet Project that ________.

A. few library customers know how to read e?books

B. the promotional effort at e?book readers is not big enough

C. library customers should be reminded about the e?book service

D. more library cards should be offered to readers free of charge

4.Why did Penguin Books NOT supply new e?books to libraries?

A. Because they are not allowed to offer e?books.

B. Because they wanted to increase the sales of printed books.

C. Because they didn't want their e?books to be copied.

D. Because their products were not welcomed there.

It’s 5:00 in the morning when the alarm (鬧鐘) rings in my ears. I roll out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD, Insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is of my face. It’s a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.

Some people enjoy shopping,smoking,food,work,or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother’s chocolate cake. They raise their eyebrows, surprised by my “no thank you,” or by my choice to have a salad. Over the years,I have learned it’s okay to just say “no.” I shouldn’t feel sorry for refusing food that I don’t want to eat.

So what drives me to roll out of bed at 5:00 a.m.? What gives me the reason to just say to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases self–confidence and energy, extends life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It’s through commitment and sweat that I can make a difference within myself inside and out.

1.Why is there a smile on the author’s face in the morning?

A. Because she sees her family sleeping peacefully.

B. Because she feels a sense of achievement.

C. Because she enjoys the interesting DVD.

D. Because she finishes her favorite exercise.

2.Which of the following is true according to Paragraph 2?

A. Others don’t understand what she does.

B. She likes to make others surprised.

C. She doesn’t like others politely.

D. Others try to help her by offering her food.

3.What does the underlined word “commitment” in the last paragraph mean?

A. Good health. B. A regular habit.

C. A strong power. D. Firm belief.

4.What can we learn about the author from the text?

A. She aims to develop a good body shape.

B. She wants to look different from others.

C. She acts in a strange way.

D. She has difficulty getting along with others.
