A．introduce B．introduced C．are introduced D．were introduced 【答案】D 【详解】句意：自从计算机被引入学校以来，它们对学习方法产生了很大的影响。 考查时态和语态。since引导的时间状语从句，从句用一般过去时，主语“they”指代“Computers”，与谓语动词introduce“引进”之间是动宾关系，所以用一般过去时的被动语态（were done）。故选D。 12．I really don’t want to know the secret. I only found it _________. A．by an accident B．by the way C．by myself D．by accident 【答案】D 【详解】句意：我真的不想知道这个秘密。 我只是偶然发现它的。 考查介词短语。by an accident表达错误；by the way顺便说一下；by myself我独自地；by accident偶然地。根据“I really don’t want to know the secret.”我真的不想知道这个秘密，可推知我只是偶然发现的，因此by accident符合语境。故选D。 13．_________ is said that there will be rain tomorrow. A．It B．This C．That D．One 【答案】A 【详解】句意：据说明天有雨。 考查代词辨析。it它；this这个；that那个；one一个。固定句式：It is said that+从句，表示“据说”，故选A。 14．They have saved a lot of time and money since the new robots _________ to their factory. A．are brought B．were brought C．brought D．bring 【答案】B 【详解】句意：自从新机器人被带到他们的工厂以来，他们节省了很多时间和金钱。 考查被动语态。分析从句主语和动词bring可知它们之间是被动关系，应用被动语态，题干是复合句，含有一个since（自从）引导的时态状语从句。主句通常用现在完成时，since从句通常使用一般过去时态，所以用一般过去时的被动语态，故选B。 15．—Our school sports meeting ________ last week. And we won the first prize. —Sounds great. Congratulations! A．happened B．took place C．was happened D．was taken place 【答案】B 【详解】句意：——我们学校的运动会上周举行了。我们赢得了一等奖。——听起来不错。祝贺！ 考查动词辨析和语态。happened（偶然地）发生；出现；took place （有计划地）发生。两者都没有被动形式。运动会应该是有计划地发生，故选B。 拓展训练 完形填空 A wind power generator (发电机) is a great way to produce electricity and to save money.
