22、e CPU.Differences1. Minicomputers are larger than microcomputers.2. Microcomputers are used more frequently in large offices and businesses than in small businesses.3. More than one person can use a minicomputer at the same time.【原文】There are two primary kinds of computers: analog computers and digi
23、tal computers. Unless you are a scientist, you probably will not use analog computers. These computers are important because they are able to measure quantities such as electricity and temperature.In contrast, digital computers perform their tasks by counting. Some digital computers are built to hel
24、p solve only a specific kind of problem. For example, digital computers that monitor airplanes flying in and out of airports are built only for that task. Most digital computers, though, can be used to help solve many kinds of problems. Among them, microcomputers and minicomputers are two kinds of c
25、ommon digital computers.Microcomputers, also called personal computers, are the newest computers. Many are about the size of a very small television set. Some, however, are so small 4and light that people can carry them easily on business trips. Because computer manufacturers produce an enormous amo
26、unt of computer hardware, it is possible for anyone to own and use a microcomputer. Therefore, we now see these machines in many homes, schools, and businesses. There is one disadvantage to these computers, though. Only one person at a time can use them. Also, many people who buy microcomputers do n
27、ot understand what these machines can and cannot do. Some experts say that almost half of all micro-computers are not used often because their owners do not spend enough time learning how to operate them efficiently.Like microcomputers, minicomputers are used in small businesses. However, they are l
28、arger than microcomputers and are used more frequently in large offices and businesses than in small businesses. Another difference is that more than one person can use a minicomputer at the same time. We call this time-sharing. Some minicomputers can have more than a hundred people time-sharing the
29、m. Each person who uses a minicomputer has a computer terminal that is connected to the minicomputer by interface wires. But even though more than one person can use a minicomputer, the computer has only one CPU. With the help of the operating system, the CPU is able to divide its time and perform f

It wasnt the typical low mechanical voice that sounded like a record being played at too slow a speed. It sounded natural. It had charm to it.“Do you have a name?“ Lupa asked.“Not y
34、et,“ the computer answered. “Theyre running a contest. The kids are supposed to name me. Im dreading the whole thing, believe me.“Now Lupa thought this was clever, the way they had programmed the computer. She wondered if there was some way to screw up the program. She had once heard that even a sop
35、histicated analog computer couldnt pick up certain subtleties in the English language, no matter how good the programming is, so she decided to give it a try.“My paws give me pause,“ she said.5The computer was silent.“My paws give me pause,“ Lupa repeated. “Its a clause without claws.“Lupa waited in
36、 silence for a response.“You know something,“ the computer said. “I thought youd be different. Just once today I was hoping Id get someone who wouldnt try to beat the program.“Lupa smiled. “This was marvelous,“ she thought to herself. “Theyd thought of everything.“Sorry,“ she said. “Mi dispiace.“Ah,
37、 you speak Italian,“ the computer said with some sarcasm.“Qui, daccord,“ Lupa answered. “Cest vrai.“And French, too. Your French is better than your Italian. Though neither one is great. Now, if youll excuse me, I have to shut down. Its closing time.“Lupa stood up and walked around the room. It was
38、evident to her that somewhere in the building, listening through an intercom was someone with a microphone. She thought about how to test for this.“You wouldnt happen to know what day of the week September the fourteenth, 1321, fell on, would you?“ Lupa asked.“It was a Sunday,“ the computer answered

40、s or software can work togetherTo access To make information available【原文】Hello. I think we can begin now if youre ready. Um, today I want to talk to you about computers, about the impact of computers on how we talk, on the ways we talk. Now of course we all know that computers have changed our live
41、s in many ways. Stop and think for a minute about how we use computers in our everyday life. Its hard to think of anything we do that hasnt been changed by computers. For example, computers allow us to get money directly from our bank accounts at cash machines. At hospitals, computers help doctors u
42、nderstand what is wrong with patients. We can use computers to help us decide which color to paint our houses, which hair styles to have, or which dresses or suits would look good on us-lots of professional and personal uses. Computers are simply a part of our lives, and, I think it is safe to say,
43、they will continue to be. What Id like to look at today is how the use of computers has had an impact on our language-how computers have changed the expressions we say, the words we use.First, let me give you some examples. These are examples from English that Id like you to think about. The first e
44、xample is this. Someone at an office says, “Wed like to have the project online by next Monday.“ In computer talk “online“ means 6started or working. So this statement means that wed like to have the project started and going by next Monday.The second example is from a discussion or seminar. Someone
45、 might say, “Lets take this discussion offline until tomorrow.“ To take a computer “offline“ means to disconnect it or take it out of the system. What do you think it means to take a discussion offline? To take a discussion “offline“ means to stop talking about it. This example means “lets stop disc
46、ussing this now and talk about it tomorrow.“The third example is: “Ill try to interface my plans with yours.“ To “interface“, in computer talk, means to do something so that different computer parts or software can work together. So “Ill try to interface my plans with yours“ means that “Ill try to c
47、hange my plans to fit with yours.“ People still say, of course, “Ill try to change my plans to fit with yours.“ But now we might also start to hear people say, “Ill try to interface my plans with yours,“ or “Lets see if we can interface our schedules so that we can meet next week.“Lets try one more
48、example. Our fourth example might take place at home. Someone says,” I just cant access where I left my car keys.” In computer talk to “access” something means to make information available. If I cant access where I left my keys, I dont have this information available for me to use. What would be an
49、other way to say this? Of course, we could also say, “I cant remember where I put my keys.”Task 6【答案】1) Cyber ethics.2) It will focus on teaching educators how to teach their students cyber ethics.3) Because its not done verbally so that people can overhear it; they think its anonymous on the Internet. 4) She was a former principal and an adjunct professor at Marymount University, teaching curriculum development and technology in the classroom.5) Young computer users do not s
