Question

【題目】I did better, but I still wasn't as focused as I ________.

A.should doB.should have been

C.should beD.should have done

Answer 1

【答案】B

【解析】

考查虛擬語(yǔ)氣。句意：我做得更好了，但我仍然沒有像我應(yīng)該的那樣專注。根據(jù)句意和did better可知表示對(duì)過(guò)去的虛擬語(yǔ)氣，排除A、C選項(xiàng)；should have done意為"本應(yīng)該做某事而沒有做"，且根據(jù)短語(yǔ)be focused on“集中于；專注”，故選B。
