　　47.D 此處需要一個動詞。本句敘述申請專利的程式：申請人申請專利時需要對發明進行具體描述，然後將描述和樣品一同提交政府官員，故填submit一詞。

　　48.O 此處需要填入一個形容詞和beneficial並列作表語。此句介紹政府官員簽發專利的條件是原創性和有用性，故填original。

　　49.A 空格前為情態動詞could，所以此處需要填入一個動詞原形。此處和or後面的use them themselves意義上是對應的。根據常識，申請人獲得專利後，專利當然可以自己使用，也可以轉讓給其他人，故填license“許可，特許”。

　　50.K 此處需要填入一個動詞原形。政府為一項發明簽發專利後，當然不能再為同樣的創意簽發專利，故填issue“簽發，發行”。

　　51.C 空格前為情態動詞could，所以此處需要填入一個動詞原形和後面的介詞of 搭配使用。句子用without 引導條件——如果沒有支付費並獲准使用就擅自使用該專利，因為專利受法律保護，發明人有權對其進行起訴。accuse和charge都有“控告，控訴”的意思，但是用法不同，分別為accuse sb. of sth.和charge sb. with sth. ,故排除charge。　　52.F 此處需要填入一個名詞作介詞for 的賓語。使用專利的人要向專利發明人支付費用，獲得使用權後才能取得專利的使用權。故填permission“許可”。

　　53.I 此處需要一個名詞。對於專利，政府一方面實施保護政策，另一方面，為了讓大眾瞭解專利的相關知識，政府會出版專利的詳細說明，所以填specifications“說明書”。

　　54.M 此處需要一個形容詞，修飾其後的名詞knowledge。政府出版專利詳細說明的目的是讓大眾能夠了解發明，所以填available“可利用的” 。

　　55.H 上一段中提到美國政府在專利申訴的14年內進行保護，在這14年申報人擁有專利的所有權，超過14年，任何人都可以免費使用該專利。此處考查固定短語 for fre“免費的”。

　　56.N 句子主謂結構完整，空格處可以填入一個副詞。publicizing ideas和定語從句中的be kept as trade secrets 之間是對比關係，因此需要填入一個表示轉折意義的副詞 otherwise。otherwise 和 however 都可以表示引導意義的轉折，但however常用插入語，其前後需要加逗號，而otherwise 不需要。
