One spring day. once the flowers have begun to open, a bee will hover (盘旋)and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.
A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, straw-like tongue into a hundred or so flowers. When the bee has had her fill, she'll fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50.000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4.000 flowers, and yet will produce only one-twelfth of a tea spoon of me.
The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad.
Unfortunately, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit. I'd appreciate your letting your own garden grow just a little wild. My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much—to you, to me—without ever asking for anything in return.
1.What does "me" refer to in the passage?
A.The flower. B.The bee.
C.Water. D.Honey.
2.What is the 2nd paragraph mainly about?
A.Bees' special talent. B.Bees’ hard work.
C.Bees' living environment. D.Bees' social behavior.
3.Which one of the following is true according to the passage?
A.A bee will always prioritize attacking picnic lovers.
B.Before "me" is sealed off in beeswax, the drying process can take a few nights.
C.The lifework of a bee satisfies the average demand of an American consumer annually.
D.Bees are more likely to visit those deliberately pest-controlled gardens.
4.What is the purpose of the passage?
A.To appeal for help for honeybees.
B.To talk about the history of a treasure.
C.To put forward techniques for gardeners.
D.To argue against the control of chemicals.

One day, gardeners might not just hear the buzz of bees among their flowers, but the whirr of robots, too. Scientists have managed to turn an unassuming drone (无人机) into a remote-controlled pollinator (授粉媒介) by attaching horsehairs coated with a special, sticky gel to its underbelly.
Animal pollinators are needed for the reproduction of 90% of flowering plants and one third of human food crops. Chief among those are bees — but many bee populations in the United States have been in steep decline in recent decades. Thus, the decline of bees isn't just worrisome because it could disrupt ecosystems, but also because it could disrupt agriculture and economy. People have been trying to come up with replacement techniques, but none of them are especially effective yet.
Scientists have thought about using drones, but they haven't figured out how to make free-flying robot insects that can rely on their own power source without being attached to a wire. “It’s very tough work,” said senior author Eijiro Miyako, a chemist at the National Institute of Advanced Industrial Science and Technology. His particular contribution to the field involves a gel, one he’d considered a mistake 10 years before and stuck in a storage cabinet. When it was rediscovered a decade later, it hadn’t dried up or degraded at all. “I was so surprised because it still had high viscosity,” Miyako said.
The chemist noticed that when dropped, the gel absorbed an impressive amount of dust from the floor. Miyako realized this material could be very useful for picking up pollen (花粉). He and his colleagues chose a drone and attached horsehairs to its smooth surface to mimic a bee’s fuzzy body. They coated those horsehairs in the gel, and then controlled the drones over lilies, where they would pick up the pollen from one flower and then deposit the pollen at another one, thus fertilizing it.
The scientists looked at the hairs under a scanning electron microscope and counted up the pollen grains attached to the surface and found that the drones whose horsehairs had been coated with the gel had about 10 times more pollen than those that had not been coated with the gel.
Miyako does not think such drones would replace bees altogether, but could simply help bees with their pollinating duties. There’s a lot of work to be done before that's a reality, however. Small drones will need to become more controllable and energy efficient, as well as smarter, with better GPS and artificial intelligence.
1.What does the underlined word “viscosity” in Para.3 probably mean?
A.Hardness. B.Stickiness.
C.Flexibility. D.Purity.
2.We can learn from the passage that ______.
A.bees disrupt both agriculture and economy
B.scientists have invented self-powered robot insects
C.bees in the United States are on the edge of extinction
D.Miyako found the special feature of the gel by chance
3.A drone works best in picking up pollen when ______.
A.its body is made like a bee’s
B.its GPS works more efficiently
C.some flowers are coated with the gel
D.horsehairs with the gel are attached to it
4.According to Eijiro Miyako, the drones ______.
A.are not yet ready for practical use
B.may eventually replace bees in the future
C.are much more efficient than bee pollinators
D.can provide a solution to economic depression

One day, gardeners might not just hear the buzz of bees among their flowers, but the whirr of robots, too. Scientists have managed to turn an unassuming drone into a remote-controlled pollinator by attaching horsehairs coated with a special, sticky glue to the under part of it.

One windy spring day, I observed young people having fun using the wind to fly their kites. Multicolored creations of varying shapes and sizes filled the skies like beautiful birds dashing and dancing in the exciting atmosphere above the earth. As the strong winds gusted against the kites, a string kept them in check.
Instead of blowing away with the wind, they arose against it to achieve great heights. They shook and pulled, but the controlling string and the clumsy tail kept them in tow(牵引), facing upward and against the wind. As the kites struggled and trembled against the string, they seemed to say, “Let me go! Let me go! I want to be free!” They flew beautifully even as they fought the forced restriction of the string. Finally, one of the kites succeeded in breaking loose. “Free at last,” it seemed to say. “Free to fly with the wind.”
Yet freedom from control simply put it at the mercy of an unsympathetic gentle wind. It flew ungracefully to the ground and landed in a twisted mass of weeds and string against a dead bush. “Free at last”. Free to lie powerless in the dirt, to be blown helplessly along the ground, and to settle down lifeless against the first roadblock.
How much like kites we sometimes are. There always exist misfortunes and restrictions, rules to follow from which we can grow and gain strength. Prohibition is a necessary counterpart to the winds of opposition. Some of us pulled at the rules so hard that we never fly fast to reach the heights we might have obtained. If we keep all the commandment(戒律), we will never rise high enough to get our tails off the ground.
Let us each rise to the great heights, recognizing that some of the prohibitions are actually the steady force that helps us climb and achieve.
1.In the passage the writer watched _______.
A. many young people enjoying the sunny day
B. many birds dashing and dancing in the sky
C. many young people flying multicolored kites
D. the strong winds blowing against the sky
2.What enables a kite fly gracefully in the sky according to the story?
A. The kite itself and strange shapes.
B. A long string and blowing wind.
C. A windy spring day and blue sky.
D. The size and a long string.
3.What didn’t happen to the freed kite?
A. It kept flying freely in the air.
B. It lay powerless in the dirt.
C. It was trapped in a dead bush.
D. It was blown helplessly around.
4.What is the purpose of the author in writing this passage?
A. To give up tips on how to fly kites effectively.
B. To warn us that freedom is actually powerless.
C. To explain that restrictions are really unnecessary.
D. To teach us a lesson that rules are important in life.
5.Which of the following is the best title of the passage?
A. Fly with Restrictions
B. Where to Fly
C. Why to Fly Kites
D. Fly to Freedom

高三英语阅读理解中等难度题查看答案及解析
Most people have heard the sound of bees among flowers. Bees live almost everywhere in the world except in the Arctic areas.
Many kinds of agriculture depend on these small, social insects. Without bees, fruit and nut growers as well as many other farmers would not have a crop.
There are more than 20,000 kinds of bees. But only honey bees make enough honey for people to use. Honeybees are highly-organized social insects. They work together in a group, called a colony（群体）. Each colony lives in a hive（蜂房）. It contains one queen bee -- she lays all the eggs from which the members of the colony come. Each colony has only a few hundred males, called drones. The majority of all bees in a colony are workers, which are all females.
Bees even have a special stomach, called a honey stomach, which is used to store sweet fluid that the bees gather from flowers. Bees also have long hairs on their body and legs. These hairs capture pollen（花粉） as bees go from flower to flower. Some of the pollen is taken back to the hive. Some, however, is passed to the next flower. This is how many plants are fertilized. Pollen is the reproductive material of plants. Many important agricultural crops depend on bees for fertilization.
Inside their hives, bees store sweet liquid from flowers and pollen as well. They may even gather sweet liquid from some other kinds of insects. These kinds of sweet liquid are also stored in the hive.
Bees make honey through a process. They add liquid from their own mouths to sweet liquid into simple sugar. As the honey is stored, it dries. It becomes thicker and darker.
Although bees are often thought of as honey makers, they provide a surprising number of products. Also, their greatest economic value is in fertilizing crops-not in making honey.
1.The passage is mainly about________.
A．bees and their colony
B．the way for bees to pass pollen
C．bees and agriculture
D．the process for bees to make honey
2.Honeybees are social insects because________.
A．they work in groups B．there is queen bee in every colony
C．they live in a hive D．each of them does the same job
3.The most valuable thing honeybees do for people is in ________.
A．making honey B．fertilizing crops
C．making flowers grow better D．producing pollen
4.The word “fertilize” in the sentence “This is how many plants are fertilized” probably means “________”.
A．to make plants strong and productive
B．to make soil rich for plants
C．to start the development of young flowers
D．to introduce pollen into plants
