Today just as technology changed the face of industry, farmers have undergone an "agricultural revolution". On the farm of today, machines provide all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog(猪) producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear(修剪) sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the special barn(畜棚), then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.Which sentence carries the main idea of the whole passage?

People have wondered for a long time how their personalities and behavior are formed. It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.
Social scientists are of course extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behavior. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from each other, and there is a great deal of debate between proponents of each theory. The controversy is often conveniently referred to as “nature and nurture”．
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological factors. That our environment has little, if anything, to do with our abilities, characteristics and behavior is central to this theory. Taken to an extreme，this theory states that our behavior is predetermined to such a great degree that we are almost completely governed by our instincts(本能)．
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claim that our environment is more important than our biologically based instincts in determining how we will act. A behaviorist, B. F. Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings. The behaviorists' view of the human being is quite mechanistic. They state that, like machines, humans respond to environmental stimuli (刺激) as the basis of their behavior.
Socially and politically, the consequences of these two theories are far-reaching. In the US，for example, blacks often score below whites on standardized intelligence tests. This leads some “nature” proponents to conclude that blacks are genetically lower in status than whites. Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do.
Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes and that the controversy will continue for a long time is certain. This passage is mainly concerned with ________.
| A．relation between personality and behavior |
| B．relation between behavior and environment |
| C．different accounts of patterns of human behavior |
| D．different theories of the formation of human behavior |
The underlined word “proponents” in Paragraph 2 means ________.
| A．creators | B．advisors | C．advocates | D．judges |
In Paragraph 5, the author mainly writes about ________.
| A．the considerable influence of the two theories |
| B．differences between the blacks and whites |
| C．racial discrimination in the United States |
| D．different responds to intelligence tests |
What's the author's purpose in writing the passage?
| A．To call our attention to the changes of human behavior. |
| B．To urge scientists to do more research in social science. |
| C．To give us a detailed explanation of human behavior. |
| D．To present an argument in the field of social science. |
The English test will be removed from China’s college entrance exam by 2020, according to details of exam and admission reform revealed by the Ministry of Education. The national college exam, known as the “Gaokao” has been used to evaluate Chinese students for three decades. The Ministry of Education has worked out a plan for reforming exams and enrollment. The Ministry will solicit(征求) public opinions before its release. Instead, tests will be held several times a year to allow students to choose when and how often they sit the exam so as to ease study pressure and change China’s once-in-a-lifetime exam system.
The plan and suggestion for its implementation(实施) will be announced in the first half of next year. It will be piloted in selected provinces and cities and promoted nationwide from 2017. A new exam and admission system will be established by 2020, according to the education ministry.
The decision has aroused a heated discussion among Shanghai educators and parents who doubted the reform would reduce the burden of learning English or if the substitute test could reflect a student’s English skills and help students learn English better.
“The reform shows China is learning from the West to give students more test-taking chances. But more chances might become more of a burden since Chinese students are likely to repeat the test until they get the highest score,” said Cai Jigang, a professor at Fudan University’s College of Foreign Languages and Literature and chairman of the Shanghai Advisory Committee for College English Teaching at Tertiary level.
Yu Lizhong, chancellor of New York University Shanghai, where classes are in English and students are required to have a high standard of English, said the most important aspect of the reform lay in what to test and how to test.
“As far as I see, the reform doesn’t mean English is no longer important for Chinese students after it will be excluded from the college entrance exam,” Yu said. “In a way, English is even more important than before since the test would only serve as reference, while every college and university, even every major, can have different requirements of a student’s English skills under a diverse evaluation system.”
Yu said some students will have their study pressure reduced if the major they choose doesn’t need excellent English while others still need to study hard if they want to be among the best students.
The education ministry said the reform would not affect students attending the college entrance exam over the next three years.What can we learn from the first paragraph?
| A．English will become less and less important in the stage of compulsory education. |
| B．It has been 30 years since English became one subject of national college entrance exam. |
| C．China’s once-in-a-lifetime exam system is unacceptable at all. |
| D．The system that tests are held several times does more good than once-in-a-lifetime exam system. |
According to the passage, Shanghai educators and parents argue that________.
| A．the new exam and admission system will make no difference. |
| B．English shouldn’t be removed from China’s college entrance exam. |
| C．the reform may accomplish the very opposite. |
| D．Western educational system does not apply to China. |

| A．Students needn’t lay a good foundation during the period of high school. |
| B．Whether students should study English hard may depend on their major. |
| C．Students can constantly struggle for perfection only in their major. |
| D．English must be close to full mark. |
What’s the purpose of the passage?
| A．To advise students not to devote themselves to English. |

| D．To encourage students to do as they have planned. |
Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers.It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages. Drier climates are of course more likely to have droughts than areas with more rainfall，but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there's a lot we can do to lower the number.
You can take steps to save water in your home.To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.Which of the following is most likely to lead to less groundwater?
| A．Using river water. | B．Throwing batteries away. |
| C．Paving parking lots. | D．Throwing rubbish into lakes. |
What can be inferred from the text?
| A．All water shortages are due to human behavior. |
| B．It takes a lot of effort to meet our water needs. |
| C．There is much we can do to reduce family size. |
| D．The average family in America makes proper use of water. |
The last paragraph is intended to________.
| A．show us how to fix leaks at home |
| B．tell us how to run a dishwasher |
| C．prove what drinking glass is best for us |
| D．suggest what we do to save water at home |
The text is mainly about________.
| A．why paving roads reduces our water |
| B．how much we depend on water to live |
| C．why droughts occur more in dry climates |
| D．how human activity affects our water supply |
While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked -- remotely -- to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the advanced technique and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid(有效的) - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |
| C．To prevent her from slowing down. |
| D．To keep her from dishonest behaviors. |
For Internet universities, exams and diplomas will be valid if _____.
| A．they can attract potential students |
| B．they can defeat academic cheating |
| C．they offer students online help |
| D．they offer many online courses |
Some programs can find out possible cheaters by _____.
| A．checking the question answering speed |
| B．producing a large number of question |
| C．scanning the Internet test question |
| D．giving difficult test question |
Which of the following is the best title of this passage?
| A．The Advantages of Online Exams |
| B．The High-tech Methods in Online Courses |
| C．The Fight against Cheating in Online Education |
| D．The War against the Booming of Online Education |
Mrs. Goff is a math teacher at Lincoln High School. Mrs. Goff and I met my freshman year. Zach Howe and I were on our way to a baseball game when he said he needed to get his stuff from Mrs. Goff’s room. I had no idea who she was then, but he said she was great. Well, he was definitely right.
Last year, I had a college math class that required me to be in the computer lab, which was located directly behind Mrs. Goff’s room. When I struggled in the section, I would go to Mrs. Goff’s and ask for assistance. She told me that I was a little too dependent and not confident enough in my ability.
A little confidence, combined with effort, will do wonders for anyone in anything. If you go into something thinking negative thoughts, negative things will happen. Mrs. Goff taught me that it was OK to make a few mistakes. Mistakes are a part of everyone’s life. She told me that it is how you learn from them that defines your character. A person that learns from his or her mistakes is more likely to be a successful person in life.
This year, I have spent a lot of time with Mrs. Goff. She really helps me instill(逐渐灌输) confidence in myself and others around me. The encouragement that she has given me made me realize that I can do the same thing for people. Therefore, she has helped my leadership skills and increased my confidence in being outgoing.
Mrs. Goff is a great role model in my life, and I appreciate everything she has done for me. I will never forget the things that she has done for me and the things she has helped me learn and accomplish throughout high school.
