試題本文簡單介紹了計(jì)算機(jī)的演變歷程。1946建造了第一臺(tái)體型龐大的計(jì)算機(jī)，運(yùn)行緩慢，很難使用。后來發(fā)明了硅芯片，計(jì)算機(jī)就變得更小、更容易、更快捷。

【1】句意：第一臺(tái)計(jì)算機(jī)是1946建成的。根據(jù)下文It was as large as a room對它外形的描述，可知選用動(dòng)詞build。句子主語The first computer是動(dòng)詞build的受動(dòng)者，需用被動(dòng)語態(tài)，結(jié)合時(shí)間1946，可知用過去時(shí)，故填was built。

【2】句意：它和房間一樣大，而且運(yùn)行緩慢，很難使用。句中的兩個(gè)and都是并列結(jié)構(gòu)，但第一個(gè)連接的是兩個(gè)句子，即and（it was）quite difficult and slow 。根據(jù)句意和結(jié)構(gòu)，可知填to use。

【3】句意：但自從硅芯片發(fā)明以來，計(jì)算機(jī)變得更小、更容易、更快捷。since自……以來，常用于完成時(shí)態(tài)，根據(jù)句意和上下文，可知填have become。

【4】句意：電腦也正變得越來越小。all the time時(shí)時(shí)刻刻，正在，常用于現(xiàn)在進(jìn)行時(shí)態(tài)。computers是復(fù)數(shù)人稱，需用are。根據(jù)句意和語境，可知填are getting。

【5】句意：誰知道明天的電腦會(huì)是什么樣子？be like像。what引導(dǎo)的句子做know的賓語，what本身則做從句的表語。根據(jù)tomorrow可知用將來時(shí)態(tài)，結(jié)合句意和結(jié)構(gòu)，故填will be。
