The longest extension ever【C8】______was to Georges Valensi; his 1939 patent for color TV receiver circuit was extended until 1971 because for most of the patent’ s normal life there was no color TV to【C9】______and thus no hope for reward for the invention.
Because a patent remains permanently【C10】______after it has terminated, the shelves of the library attached to the【C11】______office contain details of literally millions of ideas that are free for anyone to use and, if【C12】______than half a century, sometimes even re-patent. Indeed, patent experts often advise anyone【C13】______to avoid the high cost of conducting a search through【C14】______patents that the one sure way of violation of rely other inventor’s right is to plagiarize a dead patent. Likewise, because publication of an idea in any other form【C15】______invalidates further patents on that idea, it is traditionally【C16】______to take ideas from other areas of print.

选项
A、open
B、covered
C、secret
D、improved
答案
C
解析
本题应选C。本句大意是发明者将发明密而不发,所以选项中只有C secret最符合句意,keep...secret意思是“将某事保守秘密”,而其他三项A项“打开”;B项“隐蔽着的,掩藏着的”;D项“改良的”,均不合句意。
