A remarkable variety of insects live on this planet. Insects have survived on earth for more than 300 million years, and may possess the ability to survive for millions more.
Insects can be found almost everywhere—on the highest mountains, in the cold South Pole and in bubbling hot springs. They dig through the ground, jump and sing in the trees, and run and dance in the air. They come in many different colors and various shapes. Insects are extremely useful to humans,pollinating (授粉) our crops as well as flowers in meadows,forests, deserts and other areas. But some insects, such as mosquitoes and fleas, can transmit disease.
There are many reasons why insects are so successful at surviving. Their amazing ability to adapt permits them to live in extreme ranges of temperatures and environments. They can survive on a wide range of natural and artificial foods - paint, books, grain, plants and animals. Because they are small, they can hide in tiny spaces.
A strong, hard but flexible shell covers their soft organs and is resistant to chemicals, water and physical impact. Their wings give them the option of flying away from dangerous situations or toward food or mates. Also, insects have an enormous reproductive capacity: An African ant queen can lay as many as 43,000 eggs a day.
Another reason for their success is the strategy of protective color. An insect may be right before our eyes, but nearly invisible because it is cleverly disguised (伪装) like a green leaf, lump of brown soil, a seed or some other natural object. Some insects use bright, bold colors to send warning signals that they taste bad. Others have wing patterns that look like the eyes of a huge predator, confusing their enemies.
1.What does the underlined word “transmit” in Paragraph 2 mean?
A.cure. B.catch.
C.prevent. D.spread.
2.How can the insects protect themselves from chemicals?
A.Have a strong shell. B.Fly away when necessary.
C.Hide in tiny spaces. D.Change colors or shapes.
3.Why do some insects disguise like natural objects?
A.To look bad—tasting. B.To send warning signals.
C.To avoid being discovered. D.To frighten away their enemies.
4.What’s the main idea of this text?
A.How insects survive in different places.
B.Why insects can survive so successfully.
C.What insects can do to the environment.
D.Where insects can be found in quantity.

I can hear the sound of insects and feel autumn is nearing. This means my year of study at Nara University of Education is coming to an end.
The time I've spent here has flown by so quickly. It seems as if I came here a month ago,but in reality I have to go home soon. When I came here,I missed my family and friends back home and found it hard to overcome loneliness,but on the other hand,I was interested in the new environment and had a lot of fun.
I had visited Japan three times before coming to study at this university,but when I started living in Japan,many days were filled with a mixture of anxiety and excitement.

高二英语单项填空简单题查看答案及解析
Both honeybees and ants are social insects that live in groups called colonies. They survive by means of their collective intelligence. Their decision-making power is distributed throughout the group; that is, no one ant or bee makes decisions for the group. Instead, they work together. As Deborah M. Gordon, a biologist at Stanford University, says,” Ants aren't smart. Ant colonies are.”
The same is true for bee colonies. Although bees and ants are quite different physically, they have a lot in common in terms of their social behavior. Specifically, honeybees and ants have similar roles within the colony, both have communication systems, and both have the capacity for learning.
Ants communicate by using chemicals called pheromones, which can alert others to danger or to a food source. For example, when worker ants find a promising source, they let the rest of the colony know how to find it by leaving a trail of pheromones on the way back to the colony. The other ants pick up the message using their sense of smell. Bees, on the other hand, use movement to communicate with each other. Worker bees send messages to each other by means of a “dance”. Different speeds and movements send different messages. For example, when worker bees called scouts go out to find a new home for the colony, they return and do a dance for the other worker bees that indicates the location of the new home and how suitable it is. The faster the scouts dance, the better the new location is.
Honeybees and ants are both capable of learning. One Chinese study found that bees can be trained to learn and remember a route to a food source. The researchers also found that bees can be taught to recognize hidden objects and use the concepts of “sameness” and “difference” to accomplish certain tasks. Ants take this one step further. Recent American research has shown that ants not only have the ability to learn, but also can teach their foraging skills to other younger ants.
They observed that older ants accompany young ants in search of food and teach them the route and how to avoid obstacles.
As we can see, the social behavior of honeybees and ants is quite similar. Both coordinate(协调) complex actions and accomplish survival tasks by cooperating in groups consisting of many individuals. Unintelligent as they may be as individuals, as groups they often show amazing brilliance as they go about their everyday activities.
1.What do ants and bees have in common?
A.They live in similar-sized colonies.
B.They make use of collective intelligence.
C.They have small leadership groups that make all decisions.
D.They use the same methods to communicate with each other.
2.What does the speed of a bee's dance indicate?
A.The quality of a new colony location.
B.The distance to a neighboring colony.
C.The discovery of a new food source.
D.The direction to a potential food source.
3.In paragraph 4, how does the author demonstrate the idea that Honeybees and ants are both capable of learning?
A.By using statistics.
B.By explaining reasons.
C.By referencing opinions.
D.By presenting study findings.
4.What is the benefit of collective intelligence?
A.It allows the colony to reproduce more rapidly.
B.It improves work cooperation within the colony.
C.It reduces the division of labor among members.
D.It enables individuals to teach each other new skills.

A US student has just spent 30 days on an “insect diet ” – eating insects three times a day. Camren Brantley-Rios says traditional meats such as pork and beef are unable to continue and he wanted to try out what many consider the diet of the future.
Many people would find the idea of eating insects distasteful, even if it were not disgusting. Not so long ago, Brantley-Rios was among them. But for the last month he has been eating insects for breakfast, lunch and dinner.
“I’m mainly sticking to three kinds,” he says. Occasionally he has included different insects. Preparing these he “actually cried”, though he insists they were surprisingly good.
Insects consume fewer resources than animals, like pigs and cows, to produce the same amount of protein(蛋白质), Brantley-Rios says – and more than two billion people worldwide include insects in their regular diet, according to the UN Food and Agriculture Organization.
“There’s not really a need to eat insects in America because we have it so nice,” Brantley-Rios says. “We have finer meats and we’re lucky to have that luxury(奢侈), so there’s not much of a pressure to eat insects right now. But what a lot of people are trying to do is make it a little bit more marketable.”
He has ordered insects from farms that usually supply zoos, which need them “to feed certain animals”. He has always made sure the insects have been fed on an organic diet, he says, and only bought species he knows are safe to eat.
He knows that one person eating insects won’t make much difference. To have a real environmental effect, millions would have to follow his example.
1.Why has the US student tried out an “insect diet”?
A. To seek for future vegetables.
B. To advocate traditional meats.
C. To make up for the lack of meat.
D. To explore new forms of protein.
2.What can we learn about Brantley-Rios from Paragraph 2?
A. He is tired of meats like pork and beef.
B. He advised people to eat insects though disgusted.
C. He had nothing to eat but insects last month.
D. He didn’t like the idea of eating insects.
3.What does the underlined part “actually cried” in Paragraph 5 mean?
A. was scared B. was pitiful
C. was sorry D. was puzzled
4.How does Brantley-Rios guarantee the safety of his insect diet?
A. He tests each species before eating it.
B. He orders insects for certain zoo animals.
C. He feeds his insects on an organic diet.
D. He has insects raised on his own farm.

The human face is a remarkable piece of work. The astonishing variety of facial features helps people recognize each other and is vital to the formation of complex societies. So is the face’s ability to send emotional signals, whether through an unconscious red face or the artifice of a false smile. People spend much of their waking lives reading faces, for signs of attraction, hatred, trust and fraud. They also spend plenty of time trying to hide true feelings or intentions.
Technology is rapidly catching up with the human ability to read faces. In America facial recognition is used by churches to track worshippers’ attendance; in Britain, by retailers to spot past shoplifters. In China, it confirms the identities of ride-hailing drivers, permits tourists to enter attractions and lets people pay for things with a smile. Apple’s new iPhone is expected to use it to unlock the home screen.
Set against human skills, such applications might seem incremental(增值的). Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode(编码) them. Although faces are unique to individuals, they are also public, so technology does not, at first sight, interfere with something that is private. And yet the ability to record, store and analyze images of faces cheaply, quickly and on a vast scale promises one day to bring about fundamental changes to opinions of privacy, fairness and trust.
Start with privacy. One big difference between faces and other biometric data, such as fingerprints, is that they work at a distance. Anyone with a phone can take a picture for facial-recognition programs to use. Facebook's bank of facial images cannot be used by others, but the Silicon Valley giant could obtain pictures of visitors to a car showroom, say, and later use facial recognition to serve them ads for cars. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but at enormous potential cost to citizens’ privacy.
The face is not just a name-tag. It displays a lot of other information—and machines can read that, too. Again, that promises benefits. Some firms are analyzing faces to provide automated diagnoses of rare genetic conditions, far earlier than would otherwise be possible. Systems that measure emotion may give autistic(孤独症的) people a grasp of social signals they find difficult.
1.Which of the following statement about facial recognition is true according to the passage?
A. It is widely applied by Chinese in many fields.
B. It is applied to track worshippers by American churches.
C. It has been applied by Apple to unlock home screen.
D. It is applied to catch thieves by police.
2.What does the third paragraph mainly talk about?
A. Flight and the Internet surely transform human abilities.
B. Facial recognition will cause fundamental changes to minds.
C. Facial expressions are not only unique but also public.
D. Facial recognition has just the same effects as other breakthroughs.
3.From the last two paragraphs, we can infer that __________.
A. the face is superior to other biometric data
B. people can keep a balance between face and privacy
C. the face has shown many benefits especially in medicine
D. fingerprints is a powerful weapon in tracking criminals
4.What is the best title of the passage?
A. Human facial expressions B. Reading faces
C. Scientific breakthroughs D. Nowhere to hide

Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies.
Butterflies have large compound eyes(复眼), which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not “see” colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light(紫外线), which is present on many flowers and guides butterflies to honey sources.
Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae(触角), feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates.
Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Butterflies don't have ears. Instead they “hear” sounds through their wings by sensing changes in sound vibrations(振动).
Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses.
1.What can we learn from the 2nd paragraph?
A. Butterflies have good eyesight.
B. Butterflies can see in all directions and don't need to turn heads.
C. Butterflies are sensitive to bright colors including red and yellow.
D. Butterflies cannot sense the ultraviolet light.
2.How do butterflies hear sounds?
A. Using their feet to sense the vibration of things
B. Using their ears to listen directly
C. Using their wings to sense the sound vibrations
D. Using their antennae to judge the sound
3.Why do female adult butterflies carefully choose the host plants?
A. To find high-qualified honey.
B. To have a good place for living.
C. To make it easier for them to hide from the enemies.
D. To find a proper place for their eggs.
4.What does the last paragraph imply?
A. There’s a long way to understand butterflies well

C. Butterflies are the most beautiful insects in the world
D. Butterflies possess more senses than humans
5.The text mainly focuses on ________.

高二英语阅读理解中等难度题查看答案及解析
At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot.
There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can’t fly into the air from the ground. Their wings don’t produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can’t run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight.
During the hours when most enemies are active, bats gather where few animals would think to look and most can’t reach. This allows them to disappear from the world until night comes again. There’s also little competition for these resting spots, as other flying animals don’t have the ability to hang upside down.
Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract(紧缩)several muscles in your arm, which are connected to your fingers by tendons(腱);as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat’s talons(爪)close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn’t have to do anything to hang upside down.
1.Bats hang upside down because________.
A. they haven’t developed a pair of strong claws B. they can’t start to fly from the ground directly
C. they have no hind legs to support their body D. they can’t find quiet places to stay during the day
2.The third paragraph tells us that bats’ hanging upside down_______.
A. is to save their energy for night movement B. is a way to fight against flying animals
C. is a great way to hide from danger D. is a skill to compete for the flying places
3.Why can bats hang upside down easily?
A. Because their upper body is light.
B. Because they have strong muscles.
C. Because their talons are linked to muscles tightly.
D. Because their tendons are linked to their upper body.
4. What is the passage mainly about?
A. The living habits of bats. B. How and why bats hang upside down.
C. The importance of bats’ hanging upside down. D. How bats use their energy at night.
