Consignee information， if shown， must not be inconsistent with the consignee information in the tran

sport document. However，if a credit requires a transport document to be issued“to order”，“to the order of shipper”，“to the order of the issuing bank”， or“consigned to the issuing bank”， the certificate of origin may show the applicant of the credit，or another party named therein， as consignee. If a credit has been transferred，the name of the first beneficiary as consignee would also be acceptable.

从供选择的答案中选出应填入下面一段英文中______内的正确答案。 Each page element （division or section,

从供选择的答案中选出应填入下面一段英文中______内的正确答案。

Each page element (division or section, heading, paragraph, image, list, and so forth) is(1)viewed as an "object." (Microsoft calls this the "Dynamic HTML Object Model." Netscape calls it the "HTML Object Model." W3C calls it the "Document Object Model.") For example, each(2)heading on a page can be named, given attributes of text style and color, and addressed by(3)name in a small program or "script" included on the page. This heading or any other element on the page can be changed as the result of a(4)specified event such as mouse passing over or being(5)clicked or a time elapsing. Or an image can be moved from one place to another by "dragging and dropping" the image(6)object with the mouse. These event possibilities can be viewed as the(7)reaction capabilities ofthe element or object. Any change takes place immediately since all variations of all(8)elements or objects have been sent as part of the same page from the Web server that sent the page. Thus, variations can be thought ofas different(9)properties ofthe object.

Not only can element variations change text wording or color but also everything contained within a heading object can be(10)replaced with new content that includes different or additional HTML as well as different text. Microsoft calls this the "Text Range technology."

供选择的答案：

1．reaction 2．specified 3．elements 4．name 5．clicked

6．viewed 7．object 8．heading 9．replaced 10．properties

Nearly a quarter-century after a German boy tossed a message in a botde off a ship in the

Baltic Sea,hes received an answer. A 13-year-old Russian, Daniil Korotkikh, was walking with his parents on a beach when he saw something glittering lying in the sand. "I saw that bottle and it looked interesting,"Korotkikh told the Associated Press on Tuesday. "It looked like a German beer botde with a ceramic(陶瓷的)plug,and there was a message inside. " His father, who knows a litde German, translated the letter. It said:" My name is Frank, and I am five years old. My dad and I are traveling on a ship to Denmark. If you find this letter, please write back to me,and I will write back to you. " The letter,dated 1987,included an address in the town of Coesfeld. The boy in the letter,Frank Uesbeck,is now 29. His parents still live at the letters address. "At first I didnt believe it,"Uesbeck told the AP about getting the response from Korotkikh. In fact,he barely remembered the trip at all;his father actually wrote the letter. The Russian boy said he does not believe that the botde actually spent 24 years in the sea. "It would not have survived in the water all that time,"he said. He believed it had been hidden under that sand where he found it. In the web chat earlier this month, Uesbeck gave Korotkikh his new address to write to and promised to write back when he receives his letter. "Hell definitely get another letter from me,"the 29-year-old said. Uesbeck was especially thrilled that he was able to have a positive impact on a life of a young person far away from Germany.

The message in the botde was found______years later.

A．25

B．24

C．29

D．20

"Freshman fifteen" is a term which means fifteen pounds, or about seven kilograms— the wei

ght students might expect to gain in their first year of college. People used to talk about the "freshman ten." Before that, it was the "freshman five." Are freshman more inflated, or just the expression？ The fact is, many young men and women do put on extra weight when they start college. Some schools that have done research on the issue including Cornell University in Ithaca, New York, have found that freshmen gain an average of four pounds during their first twelve weeks, the equivalent of two kilograms. If weight gain continues at this rate, how long before they put on fifteen pounds？ The answer is forty-five weeks, or almost a year. The next question is, why do so many freshmen gain weight？ The answers listed by experts are not so surprising. One is poor diet: College students often eat foods high in fat and sugar and starch with no parents around to say no to junk food. Students may also miss meals. They could be in class or studying or just ... busy. In any case, those who miss meals are more likely to overeat when they do have food. Also, freshmen often use food to put their mind at ease. They have college pressures to deal with. Not only that, many are living away from home for the first time. Another reason college students gain weight is that they often do not get enough exercise. Finally, there is something else that can add up to the "freshman five" or ten or fifteen, alcohol. Alcohol is high in calories and this is especially true of beer. And, no, freshmen are not supposed to be drinking, not unless they are twenty-one, the legal drinking age in America. For many college students, the extra weight they put on in their freshman year can be as hard to escape as term papers and final exams.

Paragraph 1 is centered on______.

A．why freshmen put on weight in college

B．why freshmen worry about their weight

C．how the "freshman fifteen" gets its name

D．how the "freshman fifteen" amazes freshmen
