[单选题]甲公司获得了某医用镊子的实用新型专利，不久后乙公司自行研制出相同的镊子，并通过丙公司销售给丁医院使用。乙、丙、丁都不知道甲已经获得该专利。下列选项正确的是（ ）

丙和丁能证明其产品的合法来源，不承担赔偿责任

解析：《专利法》第11条规定：“发明和实用新型专利权被授予后，除本法另有规定的以外，任何单位或者个人未经专利权人许可，都不得实施其专利，即不得为生产经营目的制造、使用、许诺销售、销售、进口其专利产品，或者使用其专利方法以及使用、许诺销售、销售、进口依照该专利方法直接获得的产品。”可见ABC三项均不正确。《专利法》第63条第2款规定：“为生产经营目的使用或者销售不知道是未经专利权人许可而制造并售出的专利产品或者依照专利方法直接获得的产品，能证明其产品合法来源的，不承担赔偿责任。”所以，D项是正确的。

[单选题]《蒙娜丽莎》是意大利文艺复兴时期的作品。（ ）

达·芬奇

[单选题]Passage FiveSome people hate everything that is modern. They cannot imagine how anyone can really like modern music; they find it hard to accept the new fashions in clothing; they think that all modern painting is ugly; and they seldom have a good word for the new buildings that are being built everywhere in the world. Such people look for perfection in everything, and they take their standards of perfection from the past. They are usually impatient with anyone who is brave enough to experiment with new or to express himself or the age in materials original ways. It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures. If the work of art is a painting, the artist's failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is nothing.
