填空题 Translate the following English passage into Chinese．(对外经济贸易大学2012研，考试科目：基础英语)Most textiles and apparel, cheese, chocolate, and a few other products are subject to U. S. import quotas. They serve to protect domestic industry by limiting the supply and therefore raising the prices of foreign products to U. S. consumers, and by allocating production among supplying countries. For example, a quota on Swiss cheese and so permits other countries to take part of the market.Foreign governments need systems for deciding which of their companies will be able to use their quotas in the U. S. Market, and, of course, they want to get the highest possible value of exports from the allowable quantities. They use different systems to allocate quotas, including auctioning them in blocks. Holders of quotas are often allowed to sell them to other suppliers, who hope to get higher prices from their U. S. Buyers.Customs and Border Protection helps many countries entrance their quota arrangements by requiring that import shipments of quota goods be accompanied by visas issued by the designated authorities in the exporting countries. This means that if your shipment of canned tuna from Thailand reaches U. S. Customs and there is no visa among the documents, it probably cannot be entered. You can apply to the Thai consulate for a visa, but it will not be granted unless the responsible agency in Bangkok gives its approval. If you get tangled up in the Electronic Certification System(eCERT)and the Electronic Visa Information System(ELVIS), you will probably wish it were the Elvis from Graceland, not Customs.Classification specialists in district Customs offices should know the details of quotas on the items they handle, but even they cannot always tell you the annual quota on a specific item from a specific country or how much of the year"s quota is still unfilled. They can, however, translate the HS number of your product into a "Quota Category Number" and tell you where to look to find the quota level and its current status of fulfillment.
