Over the past decade, cheating—an act of academic dishonesty—has become more and more common.
The latest statistics shows more than two thirds of high school students admitted cheating on an exam last year, and—even more surprising—often the best students cheat to get to the top of their class—and they don’t think it is wrong. It’s not a big deal. Everybody is doing it.
It is a big deal! Cheating is basically wrong and must be punished.
If students easily get away with it, they might be encouraged to do it again. They won’t realize that this—in the broadest sense—is an attack on our society, which is based on values like honesty and fairness. The present spreading of cheating indicates a loss of those values and cannot be tolerated. An appropriate punishment for cheating incidents would make students aware of their misbehavior.
If no one were punished for cheating, who would ever study for an exam? Tons of papers would be lifted from websites, writing crib sheets would be more important than reviewing the subjects, and highly sophisticated cheating arts would be invented. Knowledge would only exist on the Internet and on cleverly created cheat sheets, but not in the minds of the students—a rather bad precondition to enrich our society wisely and intelligently.
Students have to learn that they have to learn. Only doing what’s right will bring them a feeling of pride and accomplishment and create self-confidence—the building blocks for a successful and satisfying life and a society that keeps its values.
1.What is more surprising is that ________.
A．cheating is very common in schools
B．over 2/3 of the students cheat last year
C．even the best students cheat on exams
D．teachers are not aware of the problems
2.How do they make the students realize their misbehavior?
A．By letting them getting away with it.
B．By telling them what is right.
C．By catching them on the spot.
D．By giving them some punishment.
3.How can students create self-confidence?
A．By knowing they have to learn.
B．By doing what is right.
C．By learning the right things.
D．By being punished when cheating.
4.What does the underlined word “lifted” mean?
A．taken B．removed C．copied D．written

More than 40% of the insects around us could become extinct in next few decades. Simultaneously, the population of the adaptable and general species like that of houseflies, cockroaches and fleas is likely to bloom.
Although some species of insects are vectors (带菌者)of serious diseases, or others destroy crop, but a world without insects is inconceivable. Their importance in interconnected ecosystems and food chains can never be undermined. Insects have essential roles in terrestrial and freshwater ecosystems as herbivores, carnivores and decomposers.
There are 17 times as many insects as humans, and these numbers are essential for proper functioning of all ecosystems. Insects are responsible for pollinating around 75% of the crops in the world and also serve as food for other creatures. They replenish soils and keep the number of pests in check.
The primary cause of this extinction is loss of habitat. Be it the grasslands or wetlands, everything is vanishing in man's quest towards intensive agriculture and urbanization.
Another cause of this decline is the excessive use of pesticides, fertilizers and introduced invasive species. As if this wasn't enough, climate change and pollution of all sorts have already started worsening their lives. Climate change may also cause emergence of new pests and other vector-borne insects.
The biggest threat of Insect Armageddon comes from Germany, where 75% of insect population have declined in just 30 years and from Puerto Rico, where due to 2 degree rise in temperature, there has been 60 fold decline in invertebrate (无脊椎的)population since the 1970s.
However, the fact that insects getting extinct is a global crisis is undisputed. But the neat thing about insects is, we all can do our bit to save them. We all can maintain pesticide-free kitchen gardens and organic farms. We can plant flowers and trees and invite them to nest again.
Maybe this tragedy would have never arisen in the first place and you would not have to read this article, if the world had stopped using all kinds of pesticides immediately after Rachel Carson had published the Silent Spring. Conserving the insect biodiversity is not our responsibility. It is a necessity because if they go, so will we.
1.Why can't we stand a world without insects?
A.For their parts in global ecology.
B.For their longer history than humans'.
C.For their shockingly large population.
D.For the appearance of new insect species.
2.What does the underlined word '"undisputed" in Paragraph 7 mean?
A.Possible. B.Doubtless
C.Exact D.Flexible.
3.Which of the following may best explain the extinction of insect species?
A.Climate change.
B.Human activities.
C.The abuse of chemicals.
D.The agriculture.
4.What is the author's purpose in writing the text?
A.Calling on us to do something to save insects.
B.Introducing the urgent situation insects are facing.
C.Presenting us ways to handle the global crises.
D.Treating differently beneficial and harmful insects.

The decline in sea ice seen in the Arctic in recent decades has been linked by scientists to the spread of a deadly virus in marine (海洋的) mammals. Researchers found that Phocine distemper virus (PDV) had spread from animals in the North Atlantic to populations in the North Pacific.
According to the Intergovernmental Panel on Climate Change, the ice has been retreating by around 12% per decade between 1979 and 2018. These sea ice changes in September (2018) are likely unprecedented (前所未有的) for at least 1, 000 years. “Between 1979 and 2018, the real proportion (比例) of multi-year ice that is at least five years old has declined by approximately 90%,” the IPCC said in their report on the oceans and the cryosphere (冰冻圈) published in September.
Against this changing background, researchers have investigated the likely spread of the PDV infection, which caused a large number of deaths among harbour seals in the North Atlantic in 2002. Melting sea ice is now connecting marine mammals, like these Steller sea lions, which were formerly separated by ice . “As animals move and come in contact with other species, they carry opportunities to introduce and catch new infectious disease, with potentially destructive effects.” said author Dr Tracey Goldstein, from the University of California, Davis.
The authors warn that this trend could continue as they believe climate driven changes in the Arctic ocean will increase. The opportunities for the spread of PDV will likely grow, with uncertain health outcomes for many species.
1.What does the word “populations” in paragraph 1 refer to?
A.The marine mammals. B.The people.
C.The virus. D.The land animals.
2.What are the statistics in paragraph 2 about?
A.The loss of sea ice. B.The formation of sea ice.
C.The effect of sea ice. D.The proportion of sea ice.
3.What does paragraph 3 try to tell us?
A.How marine mammals adapt to their habitats.
B.How a large number of seals died in the Arctic.
C.How melting ice is linked to the spread of virus.
D.How marine mammals live with the melting ice.
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Health.
C.Education. D.Nature.

A Utah man who has been in a wheelchair for more than three decades has created a pheasant hunt for people like him who need help getting into the outdoors.
Clint Robinson broke his neck after being thrown off a horse at a rodeo (竞技) 32 years ago. He’s done his best to keep getting into the outdoors to hunt and fish, the Daily Herald in Provo reports.
The event he calls “Wheelchairs in the Wild” pairs people that have physical disabilities with hunters who help them with whatever they need. Many go in off-road vehicles.
“What we’re trying to do is get new injured people back out into the field trying to get them back out, enjoying the outdoors and wildlife that’s out there and show them that there’s other things that they can do besides sitting in the house doing nothing,” Robinson said.
The youngest hunter at last year’s event was 13-year-old Missy Cowley who has spina bifida (脊柱裂). Her father loves to hunt but didn’t know how to accommodate (安排) her wheelchair. Her mother, Cindy Cowley, said it was amazing to find a program that allowed her daughter to go hunting.
“We always told her when she was little, you can do everything you want to do…but we just got to figure out a way,” Cindy Cowley said. “But we really didn’t know how we were going to get her up there to hunt.”
Missy Cowley said it was a great experience that also allowed her to meet other people who use wheelchairs. “This is wonderful. I can actually do it,” Missy said. “It was really fun. And I love being outdoors.”
Jerry Schlappi, officer from Division of Wildlife resources, who helped with the event, said Robinson is a perfect role model showing other wheelchair users with disabilities that they don’t have to give up what they love.
1.What can we know about Clint Robinson from the text?
A.He began to usea wheelchair thirty years ago.
B.He used to be interested in hunting and fishing.
C.He liked riding horses before getting disabled.
D.He is now more physically active than before.
2.What does Clint Robinson try to talk about in the fourth paragraph?
A.The benefits of his event. B.The purposes of his event.
C.The processes of his even. D.The difficulty with his event.
3.Why is much information about Missy Cowley’s family given in the text?
A.To show the effects of disabilities.
B.To explain the problem with hunters.
C.To show people’s interest in hunting.
D.To think highly of Robinson’s event.
4.What should be the best title for the text?
A.Hope Is brought back To Hunters with Disabilities.
B.Man Organizes hunting Event For Wheelchair Users.
C.Hunting Event Is Benefiting The Physically Disabled.
D.Wheelchair Users Are Supposed To Get Into Nature.

Three-Dimensional （3D） movies have been becoming more and more popular in recent years．It seems 3D TV sets may be going into family households in the near future．While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say．
"There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist （眼科医师） in Chicago．He said in a 3D movie, these people face a completely new sensory experience．"That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters．
In normal vision, each eye sees things at a slightly different angle．"When that gets processed in the brain, that creates the perception （感觉） of depth," said Dr Deborah Friedman, an ophthalmologist in New York．The images people see in three dimensions in the movies are not calibrated （校准的） in the same way that their eyes and brain are．"If your eyes are a little off to begin with, then it's really throwing a whole degree of effort that your brain now needs
to exert （竭尽全力）," he said．
Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all．He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images．
Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off．
Heineman said older 3D technology used two film projectors（放映机）, one that projected a left-eye image and one that projected a right-eye image．Three-D glasses would allow viewers to see a different image in each eye．
"People often complained of headaches and it was really because the projectors weren’t lined up," Heineman said．
Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems．
"By going to a single digital projector, those problems were solved," he said．Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty （新鲜事物）．"I suspect there will be a lot of people who say it's sort of neat, but it's not really comfortable," he said．
1.The text is mainly about ____．
A．the reasons why people like 3D movies
B．how to improve 3D technology
C．the development of 3D technology in recent years
D．causes of headaches and nausea when people watch 3D movies
2.The underlined phrase "took off" could be replaced by "______"．
A．became popular
B．flew in the sky
C．left hurriedly
D．removed one's clothes
3.This article implies that _____．
A．people do not like new things like 3D movies
B．3D TVs will completely take the place of old TV sets
C．3D technology is the most important technology ever
D．those with eye muscle problems should not watch 3D movies
4.We can learn from what Rosenberg said in the last paragraph that
A．a single digital projector could solve all the problems with 3D technology
B．people will gradually become comfortable with 3D movies and TVs
C．the appeal of 3D movies and "TVs may fade
D．most people will actually enjoy the 3D experience

Pollution’s disastrous effects on the environment have become more obvious in recent years, leading to a movement to promote energy efficiency, less reliance on fossil fuels and a reduction in air and water pollution. Most scientists agree that such changes are necessary to protect our environment from further harm.
The construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. In the United States, building and development account for 39 percent of the country’s total energy use, 12 percent of total water consumption, 68 percent of total electricity consumption and 38 percent of carbon dioxide emissions, according to the Environment Protection Agency.
Green buildings use less energy, water, create less waste and are healthier to live, work and go to school in than standard buildings. Builders of green buildings use techniques that use resources more efficiently during the entire building cycle — construction, restoration, operation, maintenance (维护) and demolition (拆毁) — than those who construct more regular buildings.
The environmental benefits of building green include the protection of ecosystems and biodiversity, improved air and water quality, less waste flowing into streams and the conservation of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live there.
The process of building green includes technical and artistic planning with nature conservation in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials long distances.
Careful site selection is important to minimize (最小化) human impact on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool breezes (微风) and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small.
Green roofs are another feature of green houses that reduce energy use and cost. These roofs are partially or completely covered with plants, which helps to keep heating and cooling costs low, prevent water running off and deal with pollutants.
Other features of green buildings often include energy and water conservation, recycling and waste reduction. In addition, renewable energy sources such as solar power, hydropower (水能) and wind power are used for heat and electricity, which greatly reduces costs and decreases the impact on the environment.
1.What is the text mainly about?
A. The necessity of promoting energy efficiency.
B. The process of building green buildings.
C. Green buildings’ effects on the environment
D. The benefits and features of green buildings.
2.According to the text, green buildings refer to the buildings that ________________________________________________.
A. use energy and resources more efficiently B. only use clean energy
C. are made of recycled materials D. produce no waste
3.Which of the following statements is TRUE about green buildings?
A. They rely on fossil fuels and solar power for heat and electricity.
B. Small buildings are less efficient in energy use than larger ones.
C. The ecosystem has to be considered when building a green building.
D. They are difficult to maintain and thus need more operating costs.
4.Green roofs are used because ________________________ ________________________.
A. they fit the surrounding environment well
B. they can help to control the temperature in the building well
C. they can keep natural water for use in everyday life
D. they are cheaper than other kinds of roofs
