听力原文： There student thieves look out. Students can easily get many research papers off the Internet. A new Website could help teachers catch copiers.
Some students research and write their term papers. Others, however, just copy them off the Internet and turn them in as their work.
Two graduate students at the University of California at Berkeley have written a program to catch the students who copy. It compares a student's paper with every other term paper on the Web.
A hundred million Web pages on the Internet are searched. The top 20 search engines are used for the search. This service can be found at www. Plagiarism.com. They also have a local database of term papers. Teachers who sign up can send their students' 'papers to the Website. Within 24 hours they know if the student did the work. Every sentence that was a word-for-word match with another sentence either found on the Internet or within our database is coded.
A U. C. Berkeley professor told his class he would use the program. Still some students copied papers. All 300 papers went through the program. In 45 papers or 15 percent of students had cut and pasted large amounts of material from different World Wide Websites.
Students that say they didn't copy can defend themselves. They can show the instructor where they got their material. Students at universities try hard to get good grades. Some students welcome the Internet research watchdog because they say it is fair to all. They think copying is wrong.
Instead of researching and writing their papers, some students ______.
A．ask other students to write their papers
B．draw pictures instead
C．copy from reference books
D．copy papers or large parts of papers from the Internet

There is much debate about the capacity and duration of the short term memory. The most accepted theory comes from George A. Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or name rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking, or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.
When making a conscious effort to memorize something, such as information for an exam, many people engage in "rote rehearsal". By repeating something over and over again, we are able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, you might attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before you get the opportunity to make your phone call, you will forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice "elaborate rehearsal". This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.
Encoding information semantically also makes it more retrievable. Retrieving information can be done by recognition or recall. Humans can recall memories that are stored in the long term memory and used often. However, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures. , the more likely a memory can be retrieved. This is why multiple choice tests are often used for subjects that require a lot of memorization.
According to the passage, how do memories get transferred to the STM？ ______
A．They revert from the long term memory.
B．They are filtered from the sensory storage area.
C．They get chunked when they enter the brain.
D．They enter via the nervous system.

While searching for the origin of personal computer, Shapiro uncovered several computing claims. Stewart Brand, founder of Whole Earth Catalog, says on his Web site that he first referred to a “personal computer” in a 1976 book; and GUI pioneer Alan Kay is said to have used the term in a paper published in 1972.
But a search on JSTOR’s general science archive turned up what Shapiro says is the earliest recorded use of personal computer, in the October 4,1968, issue of Science. The issue contains a Hewlett-Packard advertisement for its new HP 9100A. “The new Hewlett-Packard 9100A personal computer,” the ad says, is “ready, willing and able …to relieve you of waiting to get on the big computer.” The $4900 device---a desktop scientific calculator equipped with magnetic cars---does not seem like much of a computer nowadays. And at 40 pounds, it was not very personal, either. But according to Shapiro, it was the first device to be called a personal computer.
1.The term “personal computer” first appeared().
A.in Byte magazine
B.in a Hewlett-Packard ad in Science
C.in a 1974 book
D.in a paper published by Alan Kay
2.What is JSTOR ？()
A.It is an online database
B.It is an academic journal
C.It is a kind of computer software
D.It is a research organization
3.Shapiro succeeded in his research for the origin of the term personal computer by().
A.looking into the Oxford Dictionary
B.digging into magazines that are more than 150 years old
C.scanning JSTOR’s general science archive on line
D.focusing on academic journal such as Science
4.With a HP9100A, according to the Hewlett-Packard ad, you().
A.can easily get on the big computer
B.do not have to get on the big computer
C.can save a lot of money
D.will be willing and ready to do scientific work
5.What do we learn from the passage about the first device that was called personal computer？()
A.It looked very different from the PC today.
B.It was small, light and easy to carry around.
C.It was as efficient as a big computer.
D.It relieved people of a great deal of tedious work.
