Our teacher told us that light ______ faster than sound.
A．travelsB．travelled
C．travelD．will travel
A

試題分析：句意：老師告訴我們光比聲音傳播速度快。結(jié)合語(yǔ)境可知從句描述的是客觀性的動(dòng)作，故用一般現(xiàn)在時(shí)態(tài)。Light是抽象名詞，不可數(shù)，故謂語(yǔ)動(dòng)詞用單數(shù)。選A。
點(diǎn)評(píng)：英語(yǔ)中的時(shí)態(tài)主要是借助于時(shí)間狀語(yǔ)與上下文語(yǔ)境來(lái)進(jìn)行判斷。解答此類題型，首先要注意句子中的時(shí)間狀語(yǔ)，如果沒(méi)有則要通過(guò)分析上下文，結(jié)合語(yǔ)境來(lái)判斷句子的時(shí)態(tài)。
