Questions from 31 to 35 are based on the following passage: The exporter, as drawer of a draft (bill of exchange), hands the draft to his bank, the remitting bank, who in turn forwards it to the buyer through a collecting bank in the buyer’s country. A draft (also called a bill) is a written order to a bank or a customer to pay someone on demand or at a fixed time in the future a certain sum of money. If shipping documents accompany the draft, the collection is called “documentary collection.” Documentary collection falls into two major categories: one is documents against payment(D/P); the other, documents against acceptance (D/A). Documents against payment, as the term suggests, is that the collecting bank will only give the shipping documents representing the title to the goods on the condition that the buyer makes payment. Where the paying arrangement is D/A, the collecting bank will only give the buyer the shipping documents after buyer’s acceptance of the bill drawn on him, i.e. the buyer signs his name on the bill promising to pay the sum when it matures. In return he gets what he needs – the shipping documents. Under D/A, the seller gives up the title to the goods – shipping documents before he gets payment of the goods. Therefore, an exporter must think twice before he accepts such paying arrangement. The meaning of D/A is（）.

第2题：
From the text, we learn that Vinton Cerf is _____.
［A］ seeking answers to questions about the Internet web
［B］ working on interplanetary Internet with collaboration of NASA
［C］ trying to commercialize the interplanetary Internet
［D］ exploring the possibility of establishing Internet network on Mars
本题考查事实细节。第五段首句提到，塞尔夫正一直与（美）国家宇航局帕萨提那的喷气推进实验室合作，设计他所说的“星际因特网协议”，与［B］项同义。［A］项是塞尔夫在日内瓦参加的一个年会的主题，并不是塞尔夫正在从事的工作。星际因特网商业化只在文章最后一段作为可能性提到，星际因特网还没有研究出来，更不用说商业化了，所以［C］项错误。全文主要论述的是星际因特网的问题，并没有指出要在火星上建立因特网。［D］项错误。
