Between 10,000 and 15,000 years ago, some humans discontinued their wandering hunting and gathering and settled down to farm. Grain was the first domesticated crop that started that farming process.
The oldest proven records of brewing are about 6,000 years old and refer to the Sumerians. Sumeria lay between the Tigris and Euphrates rivers including Southern Mesopotamia. It is said that the Sumerians discovered the fermentation (发酵) process by chance. No one knows today exactly how this occurred, but it could be that a piece of bread or grain became wet and a short time later, it began to ferment.
The Sumerians were able to repeat this process and are assumed to be the first civilized culture to brew beer. They had discovered a “divine drink” which certainly was a gift from the gods. The word beer comes from the Latin word bibere, meaning “to drink”, and the Spanish word cerveza originates from the Greek goddess of agriculture, Ceres.
A vitamin-rich porridge, used daily, beer is reported to have increased health and longevity and reduced disease and malnutrition (营养不良). The self-medicating properties of alcohol-rich beer also eased the tensions and stresses of daily living in a hostile world. The use of yeast (酵母) was not yet known at that time. The success of the fermentation process was left to chance, as the brewers unknowingly relied on yeast particles in the air.
Considerable scientific research took place in breweries (酿酒厂) in the 19th century. A famous work from 1876 by Louis Pasteur was Studies Concerning Beer where he revealed his knowledge of micro-organisms. By establishing that yeast is a living microorganism, Pasteur opened the gates for accurately controlling the conversion (转换) of sugar to alcohol.
Another discovery in beer brewing was the work of Christian Hansen, a Danish scientist, who successfully isolated a single yeast cell and induced it to reproduce on an artificial culture medium. With the resulting yeast multiplication (繁殖) methods, the purity of the fermenting process has been improved.According to the passage, who was the first to brew beer?

The green turtle is listed as endangered by the International Union for the Conservation of Nature. Under the U．S. Endangered Species Act of 1973, the green turtle was listed as threatened except for the breeding populations in Florida and on the Pacific coast of Mexico, where it is listed as endangered.
Green turtles continue to be caught for money by humans, and the destruction and loss of nesting and foraging(觅食)sites is a serious problem. Humans have already caused the decrease of large green turtle populations, including those that once nested in Bermuda and Cayman Islands. The situation of green turtle populations is difficult to determine because of our lack of knowledge about their life cycles. The number of nests in Florida appears to be increasing, but we don’t know whether this is due to an increase in the number of nests or because we have started to monitor(监控)nesting beaches more closely.
The green turtle is the largest hardshelled sea turtle. Adults of this species commonly reach 100 cm in length and 150 kg in mass. The average size of a female nesting in Florida is 101.5 cm straight in length, with an average body mass of 136 kg.
Growth rates of green turtles have not been measured under natural conditions. Green turtles grow slowly.
In the southern Bahamas, green turtles grow from 30 to 75 cm in 17 years, and according to Bjorndal and Bolten, growth rates decrease with increasing length. Growth rates measured in green turtles from Florida and Puerto Rico fall within the range of growth rates measured in the southern Bahamas. Based on growth rate studies of wild green turtles, the researchers Balazs, Frazer and Ehrhart estimate the age of sexual maturity(成熟)can range anywhere from 20 to 50 years.The main idea of the passage is to tell us________.
| A．something about an endangered animal |
| B．how green turtles got extinct |
| C．how heavy a green turtle is |
| D．how long a green turtle can live |
Which of the following is NOT a reason why green turtles are endangered?
| A．Humans catch them to get profit. |
| B．They lose their nests. |
| C．They have fewer places to find food. |
| D．People like to keep them as pets. |
According to the passage, the green turtle________.
| A．can reach 100 cm in length in 17 years |
| B．lives in the sea and grows very slowly |
| C．lives only in Florida and on the Pacific coast of Mexico |
| D．can grow from 30 to 75 cm in 17 years in southern Florida |
Why is it hard for us to know the number of green turtles?
| A．Because it is difficult for us to be close to them. |
| B．Because we have limited knowledge about them. |
| C．Because we haven’t measured their growth rates. |
| D．Because they grow too slowly. |
When I was three years old, my parents discovered I was totally deaf. But instead of sending me to a school for the deaf, they decided to “mainstream” me. All of my peers and teachers world have normal hearing.
I was the only deaf child at Blue Creel Elementary School. From almost the first day there, the other kids made fun of me mainly because of my hearing aid and the way I talked. And I also had difficulty with most of my school work.
When the other kids made fun of me, I was sure that I was a bad person. I saw myself as a boy who wasn’t smart enough to keep up with the class.
Mrs. Jordan, my 5th grade teacher, changed all of that with a simple three-word phrase.
One morning, she asked the class a question. I read her lips from my front-row seat and immediately raised my hand because I was sure I had the right answer. But when she called on me, I was afraid. Here was an opportunity to impress the powerful teacher and show her I was worthy of her love. Maybe even impress my classmates a little. I didn’t want to blow it. despite my fears, I took a deep breath and answered Mrs. Jordan’s question.
I will never forget what happened next. Mrs. Jordan enthusiastically slammed （跺动）her right foot on the floor and turned her tight hand around in full circle until it pointed directly at me. With sparking eyes and a wide smile she cried, “THAT’S RIGHT STEPHEN!”
For the first time in my young life, I was a star. I sat a little taller in my chair.
From that day forward, my grades and speech improved greatly. My popularity among my peers increased. It was all because Mrs. Jordan believed in me and wasn’t afraid to express it. “THAT’S RIGHT STEPHEN!”What does the underlined word “mainstream”(in Para 1) mean?
| A．Encourage a disabled child to live a normal life. |
| B．Include a disabled child in an ordinary class. |
| C．Treat a disabled child with respect. |
| D．Teach a disabled child at home. |
It can be inferred that when entering Blue Creek Elementary School, the writer.
| A．was not clever | B．could not focus on his study |
| C．lacked confidence | D．got along well with other kids |
When the writer answered Mrs. Jordan’s question, he.
| A．trembled with fear | B．stayed calm |
| C．was nervous | D．was excited |
From his experience, the writer may conclude that.
| A．the right words could change someone’s life |
| B．each of us has the courage to be great |
| C．all great heroes made mistakes |
| D．each day is a lucky day |
A team of US psychologists have found that talking to another person for ten minutes a day helps with memory.
"Socializing is just as effective as more traditional kinds of mental exercise in boosting memory and intellectual performance," Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement.
In one investigation, they analyzed data on 3610 people, aged 24 to 96.
They found that the higher their level of social interaction (交流), the better their cognitive (认知的) functioning. Social interaction includes getting together or having phone chats with relatives, freinds and neighbors.
In another experiment, the researchers conducted lab tests on 76 college students, aged 18 to 21, to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests.
The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group (对照组) watched a 10-minute clip (电源片段) of the Seinfeld television show.
"We found that short-term social interaction lasting for just 10 minutes improved participants’ intellectual performance as much as engaging in so-called ’intellectual’ activities for the same amount of time," Ybarra said.
The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin.The underlined word "boosting" in the second paragraph can be replaced by ______.
| A．improving | B．decreasing | C．preventing | D．training |
Which is not included in social interaction?
| A．Having a talk with a neighbor. | B．Attending a birthday party. |

What’s the purpose of the experiment on 76 college students?
| A．To judge the effect of social interaction on memory and intelligence. |
| B．To find out what is real social interaction. |
| C．To learn how much time is needed for social interaction. |
| D．To show the function of people’s cognition. |
Which of the following questions may be asked in the social interaction group in the experiment?
| A．What does the author want to show us? |
| B．Do you like living in a big city or a small one? |
| C．Which word can be used to fill in the blank? |
| D．What is the main idea of the second paragraph? |

Are some people born clever and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both questions is yes.To some extent our intelligence is given to us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random (随意地) from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that integigence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this shows that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who lives in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.Which of the following best describes the writer’s point in Paragraph One?
| A．To some extent, intelligence is given at birth. |
| B．Intelligence is developed by the environment. |
| C．Some people are born clever and others born stupid. |
| D．Intelligence is fixed at birth, but is developed by the environment. |
In the first paragraph,“no amount of special education can make a genius out of a child born with low intelligence” suggests that .
| A．no environment can change the least able into the most able |
| B．the difference in men’s intelligence depends on the amount of their education |
| C．if a person is born clever, he is certain to be a genius |
| D．if a person is born stupid, nothing can change him into an educated person |
The last paragraph mainly shows .
| A．the importance of education |
| B．the relationship between environment and birth |
| C．the writer’s final conclusion |
| D．the relationship between intelligence and environment |
The best title for this passage would be .
| A．Dependence on Education | B．Intelligence |
| C．Surroundings | D．Effect of Education |
Which statement about the passage is true?
| A．All twins have similar degrees of intelligence. |
| B．A man who is educated in university must make greater achievements than a man who works in a boring factory. |
| C．Proper education can change one’s intelligence at some degree. |
| D．Education can’t make a child born with low intelligence cleverer. |
