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

An epidemic is the occurrence of a disease which affects a very large number of people living in an area and which spreads quickly to other people. Like infectious diseases, ideas in the academic world are spreadable. But why some travel far and wide while equally good ones remain in relative insignificance has been a mystery. Now a team of computer scientists has used an epidemiological model to imitate how ideas move from one academic institution to another. The model showed that ideas originating at famous institutions caused bigger “epidemics” than equally good ideas from less well-known places, explains Allison Morgan, a computer scientist at the University of Colorado Boulder and lead author of the new study. “This implies that where an idea is born shapes how far it spreads, holding the quality of the idea constant.” says senior author Aaron Clauset, also at Boulder.
Not only is this unfair --- “it reveals a big weakness in how we’re doing science,” says Simon DeDeo, a professor of social and decision sciences at Carnegie Mellon University, who was not involved in the study. There are many highly trained people with good ideas who do not end up at top institutions. “They are producing good ideas, and we know those ideas are getting lost,” DeDeo says. “Our science, our scholarship, is not as good because of this.”
The Colorado researchers analyzed an existing data set of computer science department hires in North America, as well as a database of publications by these hires. First they looked at how five big ideas in computer science spread to new institutions. They found that hiring a new member accounted for a little more than a third of the time --- and in 81 percent of those cases, transfers took place from higher- to lower-status universities. Then the team imitated the broadcasting of ideas using an infectious disease model and found that the size of an idea “epidemic” (as measured by the number of institutions that published studies on an idea after it originated) depended on the status of the originating institution. The findings were published online last October in EPJ Data Science.
The researchers’ model suggests that there “may be a number of quite good ideas that originate in the middle of the pack, in terms of universities,” Clauset says. DeDeo agrees. There is a lot of good work coming out of less famous places, he says: “You can learn a huge amount from it, and you can learn things that other people don’t know because they’re not even paying attention.”
1.The underlined word “this” in paragraph 2 refers to the fact that _________.
A.good ideas from less important institutions lack influence.
B.the quality of the original ideas tends to be not easy to maintain.
C.scholars in insignificant institutions consider their ideas valueless.
D.the time when good ideas were born decides how far they may spread.
2.The case of some hires in paragraph 3 is used to indicate _________.
A.why the originating institutions transfer their new findings.
B.the way the movements of some new ideas happen and their effects.
C.how they carry the ideas from lower - to higher - status institutions.
D.the statistics the epidemological model provides for the researchers.
3.Researchers such as Clauset are very much concerned about _________.
A.losing quite a number of great and creative thoughts.
B.missing the opportunities of getting more well-known.
C.misusing the epidemiological model in scientific research areas.
D.having difficulty in finding more proper science department hires.
4.Which of the following might be the best title of the passage?
A.Infectious Diseases. B.Original Ideas.
C.Epidemiological Model. D.Idea Epidemic.

Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn’t become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around. But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid-1700s, a Frenchman came up with a new design of road — a base layer (层) of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs (the central part of a wheel) came into being, followed by the pneumatic type (充气轮胎) in 1846.Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads (柏油路). As wheel design took off, vehicles got faster and faster.
1.What might explain why transport wheels didn’t become popular for some time?
A. Few knew how to use transport wheels.
B. Humans carried farming tools just as well.
C. Animals were a good means of transport.
D. The existence of transport wheels was not known.
2.What do we know about road design from the passage?
A. It was easier than wheel design.
B. It improved after big changes in vehicle design.
C. It was promoted by fast-moving vehicles.
D. It provided conditions for wheel design to develop.
3.How is the last paragraph mainly developed?
A. By giving examples. B. By making comparisons.
C. By following time order. D. By making classifications.
4.What is the passage mainly about?
A. The beginning of road design.
B. The development of transport wheels.
C. The history of public transport
D. The invention of fast-moving vehicles.
