阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

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(). They’re multicellular(多细胞的), 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(有机物) 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(样本) 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(证据) 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

 

1.D 2.D 3.A 4.B 【解析】 试题分析:文章介绍了科学家在深海没有氧气的水中发现了三种多细胞的动物,并对他们是否能真正的在如此的环境中生存进行了研究。 1. 细节理解题。根据第一段和第二段可知,科学家在深海中发现了三种生物,最让他们兴奋的是这三种多细胞动物竟然是生活在没有氧气的水中。 2. 句意理解题。第二段中说到科学家们认为只有单细胞的动物才可以在没有氧气的水中生存,多细胞动物只能到达这样的环境却不能在这样的环境中生存。所以这样的发现可能改变科学家们原来的观点。 3. 细节理解题。根据倒数第二段中的内容可知:在所取得的样本中发现了有的动物有卵;也发现了他们退去的陈旧的皮肤;他们体内的照片也发现他们适应了没有氧气的环境。所有这些都间接地证明了这些动物是不需要氧气的。 4.4】B 细节理解题。根据最后一段的第一句指出目前的证据都是间接的,要想证明这些动物是如何在没有氧气的情况下生存还需要进一步的试验。

Most people watching Jeremy Lin these past two months saw Jeremy Lin,New York Knicks star;but I,watching him,saw someone else.That was my elder brother,Bob,who is athletic and energetic. He could never sit still when he was in second grade;he had to get up every now and then and run around the room.And sure enough,he grew up to be a starting player for an NCAA championship lacrosse (长曲棍球) team.He was a Nike­endorsed marathoner,too,and reached the top of Mt.Everest,unguided,in his 50s.

And yet my family never watched his lacrosse games.We did watch some of his marathons,but that wasn’t until he was in his 20s.When Bob was in his glory days,our Shanghainese­born parents were bent on getting him into medical school.There was a loving aspect to it:I can remember my father working through math books with him,lesson by lesson,at the big blackboard in the attic.Bob never did become a doctor,though;and neither did I.It wasn’t until my younger sister came along that someone in the family finally wore a white coat.

Bob today could be the fittest 58­year­old on the planet.His doctor estimates his biological age at 35;he’s still big mountains in the Himalayas.And,like Jeremy Lin,he’s charming.No one sees Bob without leaving with a laugh.He sometimes jokes he could be mayor of his building,and it’s true.To know him is to cheer for him.

And yet my parents did not cheer for him.What if my mother had sat on the sidelines with her statistics,like Jeremy Lin’s mother?What if my father had played videos of athletes for my brother to watch and imitate?It’s hard not to wonder.

And how did Jeremy Lin’s parents manage to do these remarkable things?Amy Chua,the tiger mother,recalls her immigrant father beating the kids whenever they mispronounced a Chinese word.How is it that Jeremy Lin’s immigrant father in particular,Gie­Ming Lin,encouraged his son to follow such an untraditional path?

1.Bob’s glory days were those ________.

A.when he was doing well in math

3.Which of the following statements is probably TRUE?

A.Bob was always ignored by his parents.

B.Bob could also have been a sport star.

A.parents should always study together with their children

B.parents should know how to educate their children properly

Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has found a new recipe for success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two­thirds of the homes interviewed reported a positive relationship between their cat and dog.

However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals are just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.

In homes with cats and dogs living peacefully, researchers observed a surprising behavior. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk “Dog”, and dogs can learn how to talk “Cat”.

What's interesting is that both cats and dogs have appeared to develop their intelligence. They can learn how to read each other's body signals, suggesting that the two may have more in common than was previously suspected. Once familiar with each other's presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.

The significance of this research on cats and dogs may go beyond pets — to people who don't get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.

1.The underlined word “swimmingly” in Paragraph 1 is closest in meaning to “________”.

A.early                 B.sweetly

C.quickly                D.smoothly

2.What is found surprising about cats and dogs?

A.They eat and sleep together.

B.They observe each other's behaviors.

C.They learn to speak each other's language.

D.They know something from each other's voices.

3.It is suggested in Paragraph 4 that cats and dogs ________.

A.have common interests

B.are less different than thought

C.have a common body language

D.are less intelligent than expected

4.What can we human beings learn from cats and dogs?

A.We should learn to live in harmony.

B.We should know more about animals.

C.We should live in peace with animals.

D.We should learn more body languages.

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 all­girls,all­boys or co­ed (男女同校的) unlike our standard co­ed high schools.There are three grades:“go 1(10th)”,“go 2(11th)” and “go 3(12th)”.“Go” is the first syllable of the word “go­deung­hakkyo”,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 (标牌) 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 (装饰品) 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 ten­minute 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.attend different classes as they like

D.have different hair styles
