11、 he is going to miss the first day of biology class, although attendance is mandatory on the first day. The womans opinion about the attendance policy is that it is fair and justified.

The woman tries to give him some advice about his problem. She says he should either qu
25、it his job, or switch to a later section so that he wont miss the morning lectures. I think what he should do is switch to the later class time. Quitting the job is obviously not something he wants to do, because he clearly needs the extra income. And even though the later class is supposedly full,
26、I think the professor will probably make an exception for him and let him in the class. My professors have sometimes been able to do this for me, so I think its the best option in this case.)解析：听力原文 W: Sam, I didnt see you in accounting class this morning. M: (ashamedly) I know.

32、xplaining how to use the microscope.（分数：20.00）_正确答案：(The two major systems of the laboratory microscope are the illuminating system and the imaging system. The illuminating system has a light source that can be controlled to let more or less light pass through the specimen youre viewing when you mov
33、e a lever on the side of the microscope. The imaging system is actually a magnification feature, which can be calibrated by using the other lever to change powers. When you look through a higher power, the image appears to be larger, and conversely, when you look through a lower power, it appears to
34、 be smaller. What really means is when you use a higher magnification, the image actually shows you a smaller part of the specimen because its enlarged. Now when you switch powers, the lenses will focus automatically, but the big knob will allow you to make a rough adjustment, and the small knob wil
35、l let you make a more detailed adjustment, if you want.)解析：听力原文 All right, now that you all have microscopes at your tables, I want to explain how they work and how to use them. First of all, you should know that they are compound microscopes so they can magnify objects up to 1000 times their size.
36、These microscopes have two systems an illuminating system and an imaging system. Youll see that the illuminating system has a light source built in, and you can control it by adjusting the lever on the side. Why is this important? Well, the specimen must be pretty thin, or lets say, transparent enou
37、gh to let light pass through it. So the light source controls the amount of light that passes through the specimen. Okay. The other system provides magnification. Use this lever to switch powers. So, when you switch to a higher power, you can see a larger image, and when you switch to a lower power,
38、 you see a smaller image. But I should remind you that the field of view is smaller at a higher power. In other words, at a higher magnification, you can see a larger image of a smaller area. Okay. So what about the focus? Well, these microscopes are parfocal, and that means you should usually dont have to refocus when you switch to a higher or lower power of magnification. But there are two adjustment knobs, the larger one for coarse adjustment and the smaller one for fine adjustment just in case.
