There are more species of beetles than any other form of life. About 380 000 species of beetles are known to exist, and more are discovered all the time. There are several theories about why there are so many beetles, but fossils evidence shows that beetle species die out less than other animals, Beetle species exist in such huge number because beetles are true survivors. They refuse to die out.

One of the reasons beetles survive so well is their body design. Most beetle species have two pairs of wings. The front pair of a beetle’s wings are hard and thick. They are not used for flying. These protect the back set of wings and the beetle’s stomach. Instead, some species of beetles have lost the ability to fly, but they are still equipped with front wings. The wings protect the beetle’s soft parts from harm. These features help protect beetles, which makes them less likely to die out if they are faced with new predators (捕食性动物).

Beetles can also eat a wide range of foods. Beetle species live all over the world, and they have many different types of food available to them. Most beetles are omnivores. That means they eat both plants and animals. Their mixed diets help beetles adapt to many different habitats. Over the course of time, food sources, like certain plants and animals, do not exist anymore. Others spring up. The beetle survives because it can find something to eat, no matter what.

Finally, beetles are good at moving quickly over long distance. Any change in an animal’s environment can be dangerous to it. For example, many species died out during the Ice Age, when Earth’s temperature dropped for a long time. However, some species can avoid dangerous environment changes by moving to a new place. Research shows that beetles respond quickly to shifts in temperature. They can move to safer environments.

Beetles’ bodies and habits help give them an edge over other creatures. They are unlikely to die out. As a result, beetles make up nearly one quarter of all animal species. There are more types of beetles on Earth than there are types of plants. Some types of beetles that exist today were around during the Permian period of history, 284 million years ago. Beetles, clearly, are here to stay.

1.What is important about a beetle’s front wings?

A.They are used to catch the prey.

B.They enable the beetle to fly.

C.They help the beetle move quickly.

D.They protect the soft body parts.

2.How do beetles respond to changes of habitats?

A.They are adaptable to the food change.

B.They can change their body temperature.

C.They are adaptable to the freezing cold weather.

D.They can use their wings to fight against the cold.

3.What is the most probable title of the passage?

A.The Ice Age affected the beetles

B.Different habitats affected the beetles

C.Beetles: the six-legged survivors

D.Beetles: the unique predators

高二英语单项填空中等难度题查看答案及解析

Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole societies beyond our everyday lives.

This sense of wonder is universal. Look at the efforts that scientists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy literature or movies like The Lord of the Rings. This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us?

Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other life forms. However, people, especially in big cities, often lead rather isolated lives. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters from television shows and video games than with common wildlife. Without modem technology, a small pond could be an amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful interaction(交互) with the world around us, and sometimes even with our families and friends, we seek to understand and communicate with things that exist only in our imaginations or on a computer screen。

The world of make-believe is not necessarily bad. But when the world of fantasy becomes the only outlet(出路) for our sense of wonder, then we are really missing something. We are missing a connection with the living world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.

1.The popularity of The Lord of the Rings proves

A. the close connection between man and the fantasy world

B. the wonderful achievements of fantasy literature

C. the fine taste of moviegoers around the world

D. the general existence of the sense of curiosity

2.What can we infer from the underlined sentence in Paragraph 3?

A. People are far less familiar with the world of fantasy.

B. The world around us could serve as a source of wonder.

C. The world of fantasy can be mirrored by a small and lively pond.

D. Modern technology prevents us from developing our sense of wonder.

3. If our sense of wonder relies totally on the world of make-believe, we will

A. fail to appreciate the joy in our lives

B. be confused by the world of make-believe

C. miss the chance to recognize the fantasy world

D. be trapped by other worlds existing all around us

4. What is the main purpose of the passage?

A. To show us the hidden beauty in our world.

B. To warn us not to get lost in the fantasy world.

C. To argue against the misuse of the sense of wonder.

D. To discuss the influence of the world of make-believe.

Why texting harms your IQ

The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana (大麻). That is the statement of researchers who have found that tapping away on a mobile phone or computer keypad or checking for electronic messages temporarily knocks up to 10 points off the user’s IQ. This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have described the phenomenon of improved stupidity as “infomania”. The research conducted by Hewlett Packard, the technology company, has concluded that it is mainly a problem for adult workers, especially men.

It is concluded that too much use of modern technology can damage a person’s mind. It can cause a constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. The report also added that, in a long term, the brain will be considerably shaped by what we do to it and by the experience of daily life. At a microcellular level, the complex networks of nerve cells that make up parts of the brain actually change in response to certain experiences.

Too much use of modern technology can be damaging not only to a person’s mind, but to their social relationship. 1100 adults were interviewed during the research. More than 62 per cent of them admitted that they were addicted to checking their e-mails and text messages so often that they scrutinized work-related ones even when at home or on holiday. Half said that they always responded immediately to an email and will even interrupt a meeting to do so. It is concluded that infomania is increasing stress and anxiety and affecting one’s characteristics. Nine out of ten thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude.

The effects on IQ were studied by Dr Glenn Wilson, a psychologist at University of London. “This is a very real and widespread phenomenon,” he said. “We have found that infomania will damage a worker’s performance by reducing their mental sharpness and changing their social life. Companies should encourage a more balanced and appropriate way of working.”

1.We can learn from the passage that “infomania” ______.

A. has a positive influence on one’s IQ

B. results in the change of part of the brain

C. lies in the problem of lack of concentration

D. is caused by too much use of modern technology

2.The research mentioned in the passage is most probably about ______.

A. the important function of advanced technology

B. the damage to one’s brain done by unhealthy habits

C. the relevance between IQ and use of modern technology

D. the relationship between intelligence and working effectiveness

A. examined carefully  B. copied patiently

C. corrected quickly   D. admitted freely

4.Which of the following shows the structure of the passage?

Caring for animals, tutoring kids, helping seniors: Volunteer hours are more than a graduation must, they are life lessons.

Vilma Sooknanan cleans cat cages, Max Carroll teaches children how to cook and Michael Rosenthal rolls wheelchairs at a hospital.

What does this have to do with high school education?

Everything.

The three – and almost all other South Florida high school students – have to go outside of the classroom to earn their diplomas, doing what schools call “community service”.

Broward public schools require 40 hours to graduate. Palm Beach County public schools require 20, and most private schools require at least that much.

The purpose: To give students the chance to explore a career and create a habit of volunteering.

“We hope that when they finish high school they’ll continue service,” says Mike Roland, student activities officer for the Broward School District.

About half of U.S. public schools require community service, according to a national study. Broward School Board member Bob Parks says encouraging community service has launched all kinds of new projects, including tutoring and food collections.

Sooknanan, a student at South Broward High School, is part of the Humane Society of Broward County’s volunteer program, which is so popular that even the waiting list is closed. Students work one four-hour shift a week for four months, and leave with 64 volunteer hours.

Sooknanan changes litter boxes and puts down fresh newspaper for about 100 cats.

Combined with her volunteer hours at beach cleanups and helping teachers at school, she’s well on her way toward 250 hours, which she hopes will catch the eye of Nova Southeastern University, where she wants to study marine biology.

Carroll, a junior student at South Plantation High, has connected with FLIPANY, a nonprofit organization that offers cheap physical activity and food to low-income families. He helps teach children about cooking and healthy eating.

“It has been a life-changing experience,” says Carroll, who is now leaning toward a career as a sports trainer. "I want to find a career encouraging people to lead a healthier lifestyle.”

(Note: Answer the questions or complete the statements in NO MORE THAN 15 WORDS.)

1. How many hours of community service are students required to do to graduate from most U.S. private schools?

2. Why do some U.S. schools require students to do community service to graduate?

3. The reason Sooknanan take up so many kinds of volunteer work is that ___________.

4. Volunteer work is popular in many high schools in the U.S., not only because it is a graduation must, but also because ___________ .
