Dear professor,
Banks normally receive money from their customers in two distinct forms; on current account, and on deposit account. With a current account, a customer can issue personal cheques. No interest is paid by the bank on this type of account. With a deposit account, however, the customer undertakes (答应) to leave his money in the bank for a minimum specified period of time. Interest is paid on this money.
The bank in turn lends the deposited money to customers who need capital. This activity earns interest for the bank, and this interest is almost always at a higher rate than any interest which the bank pays to its depositors. In this way the bank makes its main profits.
We can say that the primary function of a bank today is to act as an intermediary (中间人) between depositors who wish to make interest on their savings, and borrowers who wish to obtain capital. The bank is a reservoir (水库) of loanable money, with streams of money flowing in and out. For this reason, economists and financiers often talk of money being" liquid" , or of the ' liquidity ' of money. Many small sums which might not otherwise be used as capital are made useful simply because the bank acts as a reservoir.
The system of banking rests upon a basis of trust. Innumerable acts of trust build up the system of which bankers, depositors and borrowers are part. They all agree to behave in certain predictable ways in relation to each other, and in relation to the rapid fluctuations of credit and debit. Consequently, business can be done and cheques can be written without visibly changing hands.
On______, the bank will pay interest.
A.the current account
B.personal cheques
C.the deposit account
D.both the current and deposit account

听力原文: The year is 2501, and the Earth is desperately short of fuel. All Earth's coal, oil and wood have been used up long ago, and scientists have been sent to the ends of the universe in search of alternative forms of energy.
A rich and powerful civilization has been discovered on the planet Jupiter, and Earth is supplied with fuel by constant supply fleets from that planet, but the price is very high. Unless it discovers an alternative source of energy soon, civilization on Earth will fail, and its inhabitants will have to move to other planets where they will be little more than slaves. Then Jupiter will take possession of Earth-- the most beautiful, most desirable planet in the universe.
Human scientists have been sure for a long time that Jupiter possesses a method of creating constant energy and now ten explorers on a secret mission from Earth have discovered the secret--a kind of heavy, green dust which will change salt water to high grade petroleum. This dust covers a large part of Jupiter's surface, and just a few pounds of it could solve the world's energy crisis since it would reproduce itself continuously in Earth's atmosphere.

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.
