When a pencil is partly in a glass of water, it looks as if it _______.
A． breaksB．has brokenC．were brokenD．had been broken
C
本題考查的是as if 引導(dǎo)的讓步狀語(yǔ)從句中的語(yǔ)氣問(wèn)題，as if引導(dǎo)的狀語(yǔ)從句如果與事實(shí)一致，不用虛擬語(yǔ)氣，如果與事實(shí)相反，應(yīng)用虛擬語(yǔ)氣。題中“當(dāng)鉛筆的一部分浸在水中，鉛筆看上去好像斷了”。而實(shí)際上鉛筆并未斷，與事實(shí)相反，前半部分陳述是一般現(xiàn)在時(shí)，因而本句是對(duì)一般現(xiàn)在時(shí)的虛擬，用were broken。
