听力原文： Welcome to physiology 100. I'm doctor Ann Roberts. l think everyone here is the sophomore since this is the nursing department's second year physiology course. If you are first year nursing students, please see me after class about transfering to the introductory course. OK, I'd like to begin my first lecture by introducing two important terms: vitalism versus mechanism. How many of you've heard these terms？ Oh, I see someone of you has! Well, vitalism and mechanism are two completely opposed approaches to human physiology. According to the vitalist, the laws of the physics and chemistry alone cannot explain the processes of life. To the vitalist, there is a so- called "vital force" and this "vital force" is totally separated from mental energy. As you may have guessed, vitalism is a kind of philosophical approach. Mechanism, on the other hand, is the view that all life phenomena, no matter how complex, can be explained according to chemical and physical laws, since we can support mechanism through scientific experimentations. The modem scientist tends to be a mechanist, but vitalism is not totally dismissed especially in feel, such as brain physiology. There are terms, such as human consciousness, that haven't been defined by physical and chemical terms. I recently read an interesting article that deals with the variant question that whether the mind is separated from the brain or whether the chemical is in the physiological working of the brain. I'd like to continue with this next time and so we can speak more details. I have some copies of that article and I want you to take them home and read them for next week.

Students' Evaluation of Classroom Teaching
For the past two years, I have been working on students' evaluation of classroom teaching. I have kept a record of informal conversations(51)some 300 students from at least twenty--one colleges and universities. The students were generally(52)and direct in their comments(53)how course work could be better(54). Most of their remarks were kindly taken --with tolerance rather than bitterness--and frequently were softened by the(55) that the students were speaking(56)some, not all, instructors. Nevertheless,(57)the following suggestions and comments indicate, students feel dissatisfied with things--as--they --are in the classroom.
Professors should be(58)from reading lecture notes. "It makes their(59)monotonous(单调的)."
If they are going to read, why not(60)out copies of the lecture？ Then we shouldn't need to go to class. Professors should(61)repeating in lectures material that is in the textbook."(62)we've read the material, we want to(63)it or hear it elaborated on, not repeated." "A lot of students hate to buy a(64)text that the professor has written(65)to have his lectures repeat it. '

Dear Sirs,
Two weeks ago, I sent you an order for 45 copies of the " Contemporary English" dictionary, (147) the importance of swift delivery. They should have arrived last week at the latest when the new semester was due to begin.
I have received no acknowledgement of the order, nor have the dictionaries (148).
Failure to receive them on time is causing serious inconvenience.
I shall be glad if you look into this matter as soon as possible and let me know (149) they may be expected.

听力原文： Welcome to Physiology 100. I'm Doctor Ann Roberts. I assume everyone here is a sophomore, since this is the Nursing Department second-year physiology course. If you are first-year nursing students, please see me after class about transferring into introductory course.

Well, vitalism and mechanism are two completely opposite approaches to human physiology. According to the vitalist, the laws of physics and chemistry alone can not explain the processes of life. To the vitalist, there is a so-called vital force, and this vital force is totally separate from that of energy. As you may have guessed, vitalism is a kind of philosophical approach. Mechanism, on the other hand, is the view that all life phenomena, no matter how complex, can be explained according to chemical and physical laws. Since we can support mechanism through scientific experimentation, the modern scientist tends to be a mechanist. But vitalism is not totally dismissed, especially in fields such as brain physiology, where terms such as human consciousness haven't been defined yet in physic-chemical terms. I recently read an interesting article that dealt with this very question. Is the mind separate from brain, or is the mind only the chemical and physiological workings of the brain.'？ I'd like to continue with this next time, so that we can speak in more detail. I have some copies of that article. And I want you to take it with you and read it for next week.

Dear sir,
Thank you for your kind letter of December 11, 2003. We are happy to know that our paper entitled "Purification of Clostridium perfringens phospholipas C (@-toxin) by affinity chromatography on agarose-liked egg-yolk lipoprotein" (Art no. RPP-1265) will be acceptable. We have tried to shorten and revise the manuscript. in line with the suggestion made by one of the reviewers and yourself. I am enclosing duplicate copies of the revised version. In answer to the questions raised by the reviewer, we must admit that we have not tested for lipase activity known to exist in culture of this organism. However, since our purified phospholipase C was found homogeneous by various criteria, we believe contamination with lipase, if there is any, is likely to be slight. In any case, we will test for lipase activity as soon as possible.
As to the second question, we realized that the lipoprotein in affinity adsorbent was attacked by the enzyme to a small extent; a minute amount of phosphorycholine was always detected in the break-through peak. As reported, however, the same column can be repeatedly (at least four times) without losing its affinity for the enzyme.
We still do not know whether or not all of the multiple forms of enzyme are artifacts formed exclusively during isoeletric focusing. But some evidence is now available for the presence of at least two forms of enzyme, which are separable by methods other than isoeletric focusing, i. e. CM--or DEAE--Sephadex chromatography (unpublished data). The clarification of this question is now in progress in our laboratory.
We have accepted all the suggestions penciled in by the reviewer on the original manuscript; the abbreviation SDC has been avoided. Through these revision we have succeeded in shortening the manuscript. by two pages in total, although the page numbers have been kept unchanged. In the revised manuscript. we have put the reference numbers in the right order as requested. We would like, however, to keep the designation of the figures as it was, since we believe the suggestion may be based on a misunderstanding on the part of reviewers. As suggested, we have improved the description of the essential step involved in preparation of the affinity adsorbed (page 6,5th line from the bottom of the original manuscript) as follows; "by centrifuging the mixture at 13,000g for 15 min. to discard the precipitate." I hope that these revisions and the shortened text are satisfactory and that the revised version will be acceptable for publication in Biochimica et Biophysica Acta. I also hope the revised manuscript. will reach you before January 1.
Sincerely yours,
Nobuo Ogata, M.D.

Which of the following is NOT true about UGT2817，according to the passage？
A. None，one or two working copies of UGT28 17 call be found in different people．
B. Test results would depend on numbers of working copies of UGT2B17．
C. Most Caucasians have no functional copies of UGT2B17．
D. Most Asians have no functional copies of UGT2B17．
A: Very well, we have settled everything about this transaction, except the terms of payment.
B: As you know, we prefer the L/C 20 days in advance which expires 15 days after receiving the paking list.
A: I suppose you have known our financial standing and credit well now after our long-term cooperation．We know an irrevocable L/C can ensure that the seller gets payment duly．But, on the other hand, it would increase the buying cost．Therefore, could you consider giving us D/P this time？
B: I am sorry．But our rules only allow us to accept other terms of payment by L/C, although the buyer has had two or three transactions with us before.
A: But why not if you have known the buyer's credit after several deals？
B: We hope you can understand．We have got some serious lessons from the credulity．One of them was through D/P documentary collection．When the shipment worth US ＄50000 was effected, the buyer refused to make the payment．But we can do nothing with it．And that buyer had had one or two deals before this one.
A: I see．But the flexible terms of payment will definitely bring you more orders as well as facilitate the buyers' purchasing.
B: Sure．We don't mean we won't accept other terms of payment forever．As a matter of fact, we will do so when we have known well about the buyer's credit after a real long-term cooperation.
