There are an extremely large number of antsworldwide. Each individual (个体的) ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior.
In colonies (群体) that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone (外激素), chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.
In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.
Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective (集体的) intelligence greater than you would expect from itsindividual parts.
1.We can learn from the passage that ants are ____________.
A. not willing to share food
B. not found around the poles
C. more successful than all other animals
D. too many to achieve any level of organization
2.Ants can use pheromones for______.

Large rainforests are extremely important ecosystems on our planet. They are home to a large number of animal and plant species, and they absorb vast amounts of carbon dioxide, which helps reduce global warming. These biggest ones in the world are a sight to observe.
Daintree Rainforest
The main river of the rainforest is the Daintree River, and it also includes the Daintree National Park. If you are wondering why everything seems to share the name, the reason is simple-Richard Daintree was a famous Australian geologist and photographer. Plenty of options will take you there, including a ferry.
Valdivian Temperate Rainforest
This rainforest is known to be extremely foggy and humid, but some interesting species live there. Since it is on the coast, you can witness ice sheets and glaciers as well. Getting to the rainforest is most accessible from Santiago, the capital of Chile, and a train ride or a bus is a preferred option.
Congo Rainforest
This rainforest also features a large number of different plant and animal species, including gorillas, forest elephants, and lions. Visiting this rainforest is also recommended by using a tour company, preferably by finding one in the Republic of Congo.
Amazon Rainforest
It is estimated that we can find 16,000 different tree species in the Amazon rainforest.
When it comes to other plants, animals, and insects, the numbers are even more impressive. The especially interesting thing is that there is still a large number of undiscovered species. A tour guide is advised since going through the rainforest can be dangerous, with predatory creatures(食肉动物)running around.
1.Which of the following is named after a person?
A.Daintree Rainforest. B.The capital of Chile.
C.The Republic of Congo. D.Amazon Rainforest.
2.What is recommended to visit Valdivian Temperate Rainforest?

高三英语单项填空中等难度题查看答案及解析
The stomach is an extremely strong organ, full of acid to break down each meal. In order to prevent this acid from burning a hole in our stomachs and damaging other organs, our stomach lining is specially adapted to contain the acid safely.
H. pylori are able to live in the stomach by living in the lining, safe from harsh stomach acid. These bacteria are actually pretty common in people, approximately a third of Australians have H. pylori in their bodies, but not all have symptoms.
The bacteria can eventually create infection in stomach lining, a condition known as gastritis (胃炎), by wearing away the lining and allowing stomach acid to burn away stomach tissue, causing painful ulcers (溃疡)。
Up until the 1980s, it was thought that bacteria could not survive in stomach acid. The cause of stomach ulcers was due to lifestyle choices: stress, smoking, spicy foods; the stomach acid was breaking through the lining on its own.
This belief was first questioned in 1979 by Robin Warren, an Australian pathologist, who found bacteria on a microscope slide containing the stomach lining of a patient with gastritis. In the years that followed Warren continued his research.
Warren then teamed up with Barry Marshall in 1981 and the two continued with the research, trying to separate the mystery bacteria and find a cure. Over the next three years, they tested their theories with some positive results, however the idea that bacteria could be the cause of gastritis was not widely accepted or even acknowledged.
Finally, fed up with being ignored and confident in his findings, Barry Marshall decided to test on himself. He infected himself with H. pylori and soon developed gastritis and terrible stomach ulcers. Marshall then began to cure himself by taking a dose of antibiotics (抗生素). This once and for all proved not only that bacteria could grow in stomach acid, but it could also cause gastritis and stomach ulcers.
Eventually, the world fully acknowledged Warren and Marshall's huge contribution to science and medicine and the two were awarded the Nobel prize in Medicine in 2005. Twenty-six years after Robin Warren first began his research.
1.Why did the academics initially refuse to accept that H. pylori caused gastritis?
A.Lifestyle choices caused stomach ulcers.
B.Stomach acid could break through the lining on its own.
C.They thought that bacteria couldn't survive in the stomach.
D.The Australian pathologist Robin Warren provided no evidence.
2.How did Barry Marshall prove that H. pylori caused gastritis?
A.Choosing unhealthy lifestyles. B.Introducing H. pylori to his own stomach.
C.Finding the bacteria on stomach lining. D.Growing H. pylori in the lab.
3.What can we infer from the text?
A.Scientific progress takes time. B.Science guides medical practices.
C.Warren is not a productive scientist. D.Only Marshall deserves the prize.
4.The text is most likely written to .
A.Chemists B.Patients C.Researchers D.The general public

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.

From the health point of view we are living in a wonderful age. A large number of once fatal illnesses can now be cured by modern drugs and surgery. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible killing of people on the roads. Man is opposite to the motor-car! It is a never ending battle which man is losing. Thousands of people are killed each year and we are quietly sitting back and letting it happen.
It has been rightly said that when a man is sitting behind a steering-wheel(方向盘) , his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man's worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They are rude, ill-mannered and aggressive. All their hidden frustrations and disappointments seem to be brought to the surface by the act of driving.
The surprising thing is that society smiles on the motorist and seems to forgive the behaviour. Everything is done for his convenience. Cities and towns are made ugly by huge car parks.
It is high time a world law were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are not strict and even the strictest are not strict enough. A law which was universally accepted could only have a beneficial effect on the accident rate. Here are a few examples of some things that might be done. The driving test should be made to a fixed standard and far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21 ; all vehicles should be put through strict annual tests for safety. Present drinking and driving laws (where they exist) should be mad much stricter. Driving speed should be limited on all roads. These measures may sound extremely severe. But surely nothing should be considered difficult if it results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.
1.The main idea of this passage is______.
A. traffic accidents are mainly caused by motorists
B. thousands of people in the world are killed each year
C. only stricter traffic laws can prevent accidents
D. the laws of some countries about driving are too strict
2. Which of the following is right according to the passage?
A. It is right to build huge car parks in cities and towns.
B. all the drivers must be asked to take a test every year.
C. Working by car can save time and money.
D. Society overlooks their rude driving.
3.Why does the author say" his car becomes the extension of his personality" ?
A. Driving can show his real self.
B. Driving can bring out his good character.
C. Driving can make a man excited and joyful.
D. Driving can make a man quiet and pleasant.
4.The attitude of the author is______.
