新視野大學(xué)英語視聽說教程第一冊(cè) Unit 9 Making Calculations

1. W: It sounds expensive. Why did they charge you so much for repairing the computer?

M：Well, it’s $25 for labor to start with. A new modern cost another 50 bucks. On top of that I needed a new battery, and it cost $17.

Q: How much did the man spend altogether fixing his computer?

2. W: How long are you on the Internet every day?

M：About three hours a day. I promised Dad to cut that in half, but the Internet is so slow.

Q: How much time has the man promised to spend on the Net every day.

3. W: Where did you get all these e-mails?

M：I got ten messages from classmates, one about an assignment and one from my brother. Five were spam, the annoying stuff that comes at all times.

Q: How many e-mail messages did the woman get altogether?

4. W: It takes twice as long to open my Hotmail now. I need over a minute to see my mail. Is the problem Hotmail or the ISP?

M：Forget Hotmail. I get e-mail through a local provider in ten seconds. Try it.

Q: How long did it use to take the man to get his mail?

5. W: Talking about computer, what’s the meaning of Pentium 4 and clock speed?

M：Imagine the processor of a computer as a bus. The higher the Pentium number, the larger the the bus and the more information it can carry. Clock speed tells how fast data are processed. A clock speed of 100 is half as fast as a speed of 200.

Q: How much faster is a clock speed of 200 than a clock speed of 100?
