试题本文简单介绍了计算机的演变历程。1946建造了第一台体型庞大的计算机，运行缓慢，很难使用。后来发明了硅芯片，计算机就变得更小、更容易、更快捷。

【1】句意：第一台计算机是1946建成的。根据下文It was as large as a room对它外形的描述，可知选用动词build。句子主语The first computer是动词build的受动者，需用被动语态，结合时间1946，可知用过去时，故填was built。

【2】句意：它和房间一样大，而且运行缓慢，很难使用。句中的两个and都是并列结构，但第一个连接的是两个句子，即and（it was）quite difficult and slow 。根据句意和结构，可知填to use。

【3】句意：但自从硅芯片发明以来，计算机变得更小、更容易、更快捷。since自……以来，常用于完成时态，根据句意和上下文，可知填have become。

【4】句意：电脑也正变得越来越小。all the time时时刻刻，正在，常用于现在进行时态。computers是复数人称，需用are。根据句意和语境，可知填are getting。

【5】句意：谁知道明天的电脑会是什么样子？be like像。what引导的句子做know的宾语，what本身则做从句的表语。根据tomorrow可知用将来时态，结合句意和结构，故填will be。
