英语四级考试选词填空专练题答案
47.D 此处需要一个动词。本句叙述申请专利的程序：申请人申请专利时需要对发明进行具体描述，然后将描述和样品一同提交政府官员，故填submit一词。
48.O 此处需要填入一个形容词和beneficial并列作表语。此句介绍政府官员签发专利的条件是原创性和有用性，故填original。
49.A 空格前为情态动词could，所以此处需要填入一个动词原形。此处和or后面的use them themselves意义上是对应的。根据常识，申请人获得专利后，专利当然可以自己使用，也可以转让给其他人，故填license“许可，特许”。
50.K 此处需要填入一个动词原形。政府为一项发明签发专利后，当然不能再为同样的创意签发专利，故填issue“签发，发行”。
51.C 空格前为情态动词could，所以此处需要填入一个动词原形和后面的介词of 搭配使用。句子用without 引导条件——如果没有支付费并获准使用就擅自使用该专利，因为专利受法律保护，发明人有权对其进行起诉。accuse和charge都有“控告，控诉”的意思，但是用法不同，分别为accuse sb. of sth.和charge sb. with sth. ,故排除charge。52.F 此处需要填入一个名词作介词for 的宾语。使用专利的人要向专利发明人支付费用， 获得使用权后才能取得专利的使用权。故填permission“许可”。
53.I 此处需要一个名词。对于专利，政府一方面实施保护政策，另一方面，为了让大众了解专利的相关知识，政府会出版专利的详细说明，所以填specifications“说明书”。
54.M 此处需要一个形容词，修饰其后的名词knowledge。政府出版专利详细说明的目的是让大众能够了解发明，所以填available“可利用的” 。
55.H 上一段中提到美国政府在专利申诉的内进行保护，在这申报人拥有专利的所有权，超过，任何人都可以免费使用该专利。此处考查固定短语 for fre“免费的”。
56.N 句子主谓结构完整，空格处可以填入一个副词。publicizing ideas和定语从句中的be kept as trade secrets 之间是对比关系，因此需要填入一个表示转折意义的副词 otherwise。otherwise 和 however 都可以表示引导意义的转折，但however常用插入语，其前后需要加逗号，而otherwise 不需要。
