In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
　The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
　On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
　Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
　Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?
小題1:55.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?

A．The whole world becomes extremely cold

B．All the coastal cities in Africa are destroyed

C．The visit of the comet results in wars

D．The whole mankind becomes extinct

小題2:56.Why does the author mention dinosaurs at the end of the passage?

A．Because they could only live in the warm climate

B．Because their extinction indicates future disasters

C．Because they once dominated the earth

D．Because dinosaurs and humans never live in the same age

小題3:57.In writing the passage, the author intends to ______.

A．give an accurate description of the possible disaster in the future

B．prove that humans will sooner or later be destroyed

C．warn of a possible disaster in the future

D．tell the historical development of the Earth

小題4:58.It can be concluded that the passage is most probably part of a(n) ______.

A．article of popular science	B．news report
C．research paper	D．horror story

小題1:D
小題2:B
小題3:C
小題4:A

Tre’S mom，Christina Thompson, cannot believe how much her son already learned this year in his full-day, free pre-school class in Oklahoma City. “Since he’s been in school his vocabulary has increased surprisingly,” Thompson says. “The other day he came home and said, ‘You know what ，mom? You are being ridiculous，” Thompson laughs quietly. “And then he asked, ‘Do you know what ‘ridiculous’ means, mom?’” Tre knows the entire alphabet, his numbers to 100，and he’s starting to read. And letters and numbers aside, Thompson is most struck by how fast Tre is absorbing vocabulary and language.
Of course, not all pre-school is created equal. High quality pre-schools have well-trained, well-educated teachers in the classroom (much like Tre Thompson’s teacher Mrs. Wallace, who uses play-based learning to teach both academics and social skills and can rattle off (飛快說出） a battery of data on how well her students are progressing towards their year-end goals). Texas can also offer a model for educator development: its Texas School Ready! Campaign has proven to increase the quality of participating pre-schools by providing early childhood teachers with coaching, professional development, research-based curriculum (課程)，and progress monitoring. States and districts should also combine pre-school with the K-12 system, as Oklahoma does ，so that children enter kindergarten smoothly.
Oklahoma is one of the leading states in providing students like Tre with free ，full-day pre-school. And the results are already paying off: According to a 2012 study, Oklahoma kids that went through pre-school showed vocabulary gains 28% higher than those of children without pre-school, and math gains 44% higher than non-pre-school kids. And we know that high-quality pre-school doesn’t just mean higher scores in elementary school. They were more likely to have graduated from high school and less likely to have committed a violent crime. They also earned more money and were more likely to be employed.
We know pre-school works, so let’s stop talking and start building a system where all children have access to excellent early childhood education. As any well-educated four year old could tell us, not doing so would be ridiculous.
小題1:The case of Tre in the first paragraph serves as the evidence of______.

A．children’s disrespect towards parents

B．the bad performance of students at school

C．the positive effect of pre-school on children

D．Thompson’s doubt about her son’s education

小題2:At high quality pre-schools, children may learn by______

A．playing

B．modelling

C．researching

D．monitoring

小題3:It can be inferred that______.

A．children can not enter kindergarten without pre-school

B．Oklahoma is the best state offering full-day pre-school

C．all pre-schools have well-trained, well-educated teachers

D．kids with pre-school may be better equipped for their future

小題4:What would be the best title for the passage?

A．Not all pre-school works

B．All pre-school is created equal

C．We owe our kids universal pre-school

D．Pre-school goes well with K-12 system

Pupils remember more and behave better when 3D images are used in lessons, research suggests. They are quicker to learn and absorb new concepts, and display higher levels of concentration.
Professor Anne Bamford, of the University of the Arts, London, studied the effectiveness of 3D content in 15 schools across seven countries, including the UK. Pupils in 3D classes could remember more than those in the 2D classes after four weeks, improving test scores by an average 17 percent compared with eight percent for 2D lessons. They gave more detailed answers to the tasks and were more likely to think in 3D, using hand gestures and mime (模仿動作) to answer the test questions successfully.

The teachers commented that the pupils in the 3D groups had deeper understanding, increased attention span, more motivation and higher engagement in the lessons
Children are used to 3D with the rise of computer games that use the technology—90 percent of those in the study had seen a 3D film. Schools would need 3D-enabled projectors（投影儀）, laptops with good picture capabilities, 3D software and glasses for children to introduce animations (動作) into classrooms.
But Danny Nicholson, an educationist, said the technology would be impractical to use in schools and could be too expensive. He said,“While I think the idea of 3D technology is very interesting, I worry that 3D is a bit of an expensive gimmick (小玩意兒). There are a few cases where a true 3D image might help, but most of the time, good 2D models that can be moved , would be just so effective.”
In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms. And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils. Those who watched the 3D presentations were more engaged and reported a general increase in their interest in science compared with students who watched the 2D version.
小題1:Teachers think pupils in 3D classes .

A．are naughtier than those in 2D classes	B．have less motivation
C．find it hard to concentrate	D．have deeper understanding

小題2:Danny Nicholson tends to think that .

A．many pupils prefer 2D models

B．3D is a bit expensive for some schools

C．true 3D images would not help in classes

D．3D technology has a bright future in classes

小題3:What can we learn from the last paragraph?

A．3D classes will soon be given in one school district in Colorado.

B．Teachers will use the 3D technology through specific training.

C．Many pupils are now more interested in science than before.

D．3D technology will replace 2D models in the future.

小題4:What is the text mainly about?

A．2D models are always more effective than 3D images.

B．The differences between 3D and 2D images.

C．How schools can make full use of 3D technology.

D．Pupils behave better when 3D images are used in classes.

小題5:Where is the text most probably taken from?

A．A history book.	B．A news story
C．A science magazine.	D．A school report.

Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming（旅鼠）, that periodically killed themselves together, and no one knows just why!
The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life.
However, when the lemmings’ food supply becomes too low to support the population, a singular migration（遷徙）begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea.
The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown.
A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening.
小題1:The passage is mainly about______.

A．how lemmings find food

B．why animals kill themselves

C．the lemmings’ self-killing

D．the food supply in the Scandinavian mountains

小題2:A reason for the lemmings’ self-killing might be that they______.

A．go mad from a lack of food

B．hope to find fish for food

C．decide to reduce the population

D．think they can cross the sea

小題3:Why are scientists curious about the lemmings’ behavior?

A．Because they are the only animals that live in Scandinavia.

B．Because it is very unusual for animals to kill themselves.

C．Because of the amount of food they can eat on their march to the sea.

D．Because they can gather together in such huge numbers.

小題4:The underlined word “singular” means______.

A．unusual

B．single

C．wonderful

D．common

In 1883. John Roebling was inspired by an idea to build a spectacular bridge connecting New York with the Long Island. However, bridge building experts throughout the world thought this was an impossible feat and told Roebling to forget the idea, but Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he managed to convince his son Washington, an up and coming engineer, that the bridge in fact could be built.
The project started well, but when it was only a few months underway a tragic accident on the site took the life of John Roebling. Washington was injured and left with a certain amount of brain damage, which resulted in him not being able to walk or talk or even move.
"We told them so." "Crazy men and their crazy dreams.'' "It's foolish to chase wild visions." Evcryone had a negative comment to make and felt that the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap, Washington was never discouraged.
One day he was lying on his bed in hospital, seeing the sky and the tops of the trees outside for just a moment with the sunlight streaming through the windows, and a gentle breeze bowing the flimsy white curtains apart when an idea hit him. He decided to make the best use of the only finger he could move. Thus, he slowly developed a code of communication with his wife.
He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. It seemed foolish but the project was under way again.
For 13 years Washington tapped out his instructions with his finger on his wife's arm until the bridge was finally completed.
小題1:Which of the following is true of Washington and his father?

A．They are hardworking and courageous.

B．They are stubborn and bold.

C．They are creative and persistent.

D．They are curious and modest.

小題2: In the third paragraph, the underlined phrase''wild vision" refers to______.

A．the tragic accident	B．the building of the bridge
C．the brain damage	D．the discussion and persuasion

小題3: What can we learn about Washington's wife?

A．She could understand Washington and helped him a lot.

B．She cnuldn't understand him but took good care of him.

C．She didn't like Washington's idea about building the bridge.

D．She took the responsibility to continue building the bridge.

小題4:From the passage, we know that_______when Roebling proposed building the bridge.

A．people all over America supported him

B．almost no bridge experts in the world supported him

C．his friends were strongly in favor of his idea

D．many people considered it would be a great fe

小題5: The passage suggests that______.

A．NO pains, no gains.

Among the Boys is a unique after-school program for boys living in the Highland Park neighborhood of our city. The organizational task is to provide males living in low-income and public housing with opportunities to discover their ability to change challenges into possibilities. The program includes an academic part as well as specific plans for supporting the overall development of the participants. Among the Boys uses painting as an instrument for helping boys examine their world, discuss it, and develop positive ways of handling the challenges they face daily. Young men present personal challenges to the group, such as a recent fight or the long-term drug abuse they observe in their neighborhood. After guided discussion, the youth work as a team, determining how to best represent the issue at hand in a painting. The resulting paintings and explanations of these paintings provided by the young people suggest that something profound(深遠的) occurs through this process. These young men are learning a healthy way to express and cope with the pain and suffering they feel. Art serves as a healing process and a structured method of teaching teamwork, nonviolent values, conflict handling and problem-solving skills.
Activities in Among the Boys are in agreement with the best practices in the prevention of high-risk behavior. First, community-based youth development programs are considered important parts of a comprehensive prevention method, particularly in high-risk neighborhoods. Second, compensatory(補償) education that targets at risk youth for academic failure is also considered an effective prevention method. Third, interventions(介入) aimed at improving youth’s moral reasoning, social problem-solving, and thinking skills are reported to be effective methods for reducing violence in high-risk populations, especially when carried out with elementary school-aged boys. Finally, Among the Boys has an adapted tutoring part, considered an effective prevention tool. Tutoring is typically a one-to-one match between a tutor and a youth, but Among the Boys employs what is referred to as “group tutoring.” Among the Boys makes up for its high student-tutor ratio(比例) with quality and quantity of time, as the program meets after school, on Saturdays, and all day during the summer, and is staffed primarily by males, an unusual quality among educational programs.
Among the Boys is rare and successful form of grassroots program, and represents the dream of a successful male who grew up in the Highland Park neighborhood and has returned to make a valuable contribution to his community.
小題1:Which of the following most accurately describes the organization of the second paragraph？

A．A theory is presented and proved with data.

B．A statement is made and supported with examples.

C．A problem is put forward and solutions are suggested

D．A situation is described and a prediction is provided

小題2: Which of the following statements is implied in the passage?

A．Art programs can promote painting but cannot prevent school failure.

B．Social problem-solving skills are not important for high school-age youth.

C．Most educational programs have some female staff members.

D．Teamwork produces better paintings than does independent work.

小題3: In discussing Among the Boys’ tutoring part, the author implies that ______.

A．Among the Boys employs a traditional tutoring model

B．tutoring is effective only with elementary school-age boys

C．tutoring prevents the youth’s attention from wandering off

D．increased hours with a group can be as effective as a one-to-one tutoring relationship

小題4:The founder of the program described in the passage ______.

A．sought contributions to make his program successful

B．designed the program for the same neighborhood in which he grew up

C．is seeking reelection for the Highland Park community school board

D．was a successful graduate of Among the Boys when he was a youth

小題5: The attitude of the author of the passage toward Among the Boys is ______.

A．forgiving

B．doubtful

C．praising

D．ignorant

Last night’s meteor (流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothschild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.
“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment.”
Astronomers—scientists who study stars and planets—have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.
There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats, frogs, snakes, etc. For example, outdoor lighting severely affects migrating (遷徙的) birds. According to the International Dark-Sky Association, “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”
Countless more animal casualties (傷亡) result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings. But some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase a person’s chances of getting cancer.
Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.
小題1:It happened last night that _____.

A．the city’s lights affected the meteor watching

B．the meteors flew past before being noticed

C．the city light show attracted many people

D．the meteor watching ended up a social outing

小題2:What do the astronomers complain about?

A．Meteor showers occur less often than before.

B．Their observation equipment is in poor repair.

C．Light pollution has remained unsolved for years.

D．Their eyesight is failing due to artificial lighting.

小題3:What is the author concerned about according to Paragraph 4?

A．Birds may take other migration paths.

B．Animals’ living habits may change suddenly

C．Varieties of animals will become sharply reduced

D．Animals’ survival is threatened by outdoor lighting.

小題4:Lighting regulations in Flagstaff, Arizona are put into effect to _____.

A．lessen the chance of getting cancer

B．create an ideal observation condition

C．ensure citizens a good sleep at night

D．enable all creatures to live in harmony

小題5:What message does the author most want to give us?

A．Saving wildlife is saving ourselves.

B．Great efforts should be made to save energy.

C．Human activities should be environmentally friendly.

D．New equipment should be introduced for space study..
