1-16 W: I tried for half an hour for print my paper on that laser printer downstairs, but it kept jamming, do you have any suggestion?
M: That’s certainly news to me. So you can’t be completely reliable for me.
What does the man imply?
A He is surprised that the printer is not working properly.
B He is not familiar with the laser printer.
为何选择A, 不选B. 我做了多遍PP都是选择B, 到Banlv时才知道是A

2-25 M: It’s such a beautiful day. Too bad I got to work in a computer lab afternoon.
W: At least my botany lab meeting’s in the green house. I guess it could be worse.
What does the woman imply?
A She prefers being in the greenhouse to the computer lab.
B She doesn’t like her botany class.
