Question

In my opinion, life in the twenty-first century is much easier than ___________.

A．that used to be	B．it is used to
C．it was used to	D．it used to be

Answer 1

D

試題分析：句意：我認(rèn)為，生活在21世紀(jì)要比過(guò)去容易得多。 than 引導(dǎo)的是一個(gè)比較從句，同一個(gè)人或物，現(xiàn)在和過(guò)去兩個(gè)不同的時(shí)間進(jìn)行對(duì)比時(shí)，應(yīng)該用人稱(chēng)代詞，因此要有主語(yǔ)it，而used to be 是“曾經(jīng)的那個(gè)樣子”之意。故選D。
