听力原文：W: Hi, Tom.
M: Judy, I haven't seen you in weeks. Where have you been？
W: In Florida.
M: What, vacationing while the rest of us have been studying on campus in the February cold.
W: Not exactly, I spent most of my time underwater.
M: I don't understand.
W: I was on a special field trip. I went with my marine biology class.
M: So you went diving. What were you looking for, sunken treasure？
W: You might say that. The sea is full of treasures, all kinds of strange fascinating organisms. Our class concentrated on studying plankton.
M: I thought plankton was too small to be seen.
W: That's a common misconception. The term Plankton covers a wide variety of freely floating plants and animals from microscopic one-celled organisms to large ones such as the common jellyfish.
M: Jellyfish may be large enough to be seen, but they are transparent, aren't they？
W: Yes, most plankton have transparent tissues as a protective cover-up. It makes them practically invisible to predators.
M: But not invisible to your biology class, I hype.
W: By concentrating, I was able to see the outlines of lots of different plankton, plants and animals. In fact, our professor even took photographs of small oceanic snails.
M: That sounds like an interesting trip. But I think if I'd been in Florida in February, I'd much rather spend my time just swimming and lying in the sun.

听力原文： Mass media is the term used to denote, as a class, that section of the media specifically conceived and designed to reach a very large audience. It emerged in the 1920s with the advent of nationwide radio networks and of mass-circulation newspapers and magazines.
Media is a contraction of the term media of communication, referring to those organized means of dissemination of fact, opinion, and entertainment such as newspapers, magazines, cinema films, radio, television, and the World Wide Web.
During the 20th century, the advent of mass media was driven by technology that allowed the massive duplication of material at a low cost. Physical duplication technologies such as printing, record pressing and film duplication allowed the duplication of books, newspapers and movies at low prices to huge audiences. Television and radio allowed the electronic duplication of content for the first time.
In a democratic society, an independent media serves to educate the public about issues regarding government and corporate entities.
During the last decade of the 20th century, the advent of the World Wide Web marked the first era in which any individual could have a means of exposure on the scale of mass media.
(33)
A．Influence of mass media on our lives.
B．Profitability of mass media.
C．Mass media and its short history.
D．Mass media and politics.

Across a wide variety of fields, data are being collected and accumulated at a dramatic pace. There is an urgent need for a new generation of computational theories and tools to assist humans in(1)useful information (knowledge) from the rapidly growing(2)of digital data. These theories and tools are the subject of the emerging field of knowledge discovery in database (KDD). At an abstract level, the KDD field is concerned with the development of methods and techniques for making(3)of data. The basic problem addressed by the KDD process is one of mapping low-level data (witch are typically too voluminous to understand and digest easily) into other form that might be more(4)(for example, a short report), more(5)(for example, a descriptive approximation or model of the process that generated the data), or more useful (for example, a predictive model for estimating the value of future cases), at the core ofthe process is the application
of specific data-mining methods for pattern discovery and extraction.
Which of the following statements can be inferred from the passage？
A．Despite the great prospect some scientists hold, artificial intelligence has achieved a modest Success.
B．With its commercial application in medical diagnosis, artificial intelligence has made a greatest breakthrough.
C．Artificial intelligence has found a wide application in almost every field of society.
D．It is too ideal to be true to make a machine think like human beings.
The term biological clock is applied to the means, which living things 【M1】______
adjust their activity patterns, without any obvious cue, the time of day, or 【M2】______
the month, or the year. They are affected but little, if at all, by drugs,
chemical, or wide temperature differences—factors may alter substantially 【M3】______
the rates of all ordinary processes of the body.
The nature of the biological clocks mechanism is still a mystery. Two 【M4】______
quite different theories have been advanced to account to them. According 【M5】______
to the first of these theories, each individual have evolved, aided by natural
selection, an adaptation to the rhythmic environment. It has now 【M6】______
become independence on the environment. According to this view, the clocks 【M7】______
are not perfect timers. They require regular corrections by the natural light
and tide cycles and the changed lengths of the day throughout the year. 【M8】______
The other theory holds up living things react continuously to their 【M9】______
rhythmic physical environment. The setting of their biological clocks,
therefore, involves a constant adjustment to subtle clocks are potential 【M10】______
perfect timers.

The basic argument for the one-term, six-year presidency is that the quest for reelection is at the heart of our problems with self-government. The desire for reelection, it is claimed, drives Presidents to do things they would not otherwise do. It leads them to make easy promises and to postpone hard decisions. A single six-year term would liberate presidents from the pressures and temptations of politics. Instead of worrying about reelection, they would be free to do only what was best for the country.
The argument is superficially attractive. But when you think about it, it is profoundly antidemocratic in its implications. It assumes Presidents know better than anyone else what is best for the country and that the people are so wrongheaded and ignorant that Presidents should be encouraged to disregard their wishes. It assumes that the less responsive a President is to popular desires and needs, the better President he or she will be. It assumes that the democratic process is the obstacle to wise decisions.
The theory of American democracy is quite the opposite. It is that the give-and-take of the democratic process is the best source of wise decisions. It is that the President's duty is not to ignore and override popular concerns but to acknowledge and heed them. It is "that the President's accountability to the popular will is the best guarantee that he or she will do a good job.
The one-term limitation, as Gouverneur Morris, final draftsman of the Constitution, persuaded the convention, would "destroy the great motive to good behavior," which is the hope of reelection. A President, said Olive Ellsworth, another Founding Father, "should be reelected if his conduct prove worthy of it. And he will be more likely to render himself worthy of it if he be rewardable with it."
The ban on reelection has other perverse consequences. Forbidding a President to run again, Gouverneur Morris said, is "as much as to say that we should give him the benefit of experience, and then deprive ourselves of use of it." George Washington stoutly opposed the idea. "I can see no propriety," he wrote, "in precluding ourselves from the service of any man, who on some great emergency shall be deemed universally most capable of serving the public."
A single six-year term would release Presidents from the test of submitting their records to the voters. It would be an impeachment of the democratic process itself. The Founding Fathers were everlastingly right when they turned down this well-intentioned but ill-considered proposal 200 years ago.
The main idea of the passage is that the United States Presidents should ______
A．have wide political experience
B．serve for a term of less than six years
C．serve for a term of more than six years
D．be allowed to be reelected

One study in the United States found that thirty- eight percent of foreign students said they had no close American friends.
Elisabeth Gareis teaches in the Department of Communication Studies at Baruch College in New York. She says efforts on how to improve relationships between foreign and American students have yet to be studied in detail.
