D
解析：
試題
分析：考查時(shí)態(tài)。本題的關(guān)鍵在于對(duì)前半句虛擬語(yǔ)氣的理解。句意：如果Joe了解汽車(chē)方面的知識(shí)，我確信他會(huì)幫助我修理汽車(chē)。但是他懂的比我們還少。根據(jù)If Joe knew anything about car mechanics, I’m sure he would help us fix the car。這個(gè)虛擬語(yǔ)氣中的條件句中使用knew以及主句中使用would help說(shuō)明是對(duì)現(xiàn)在事實(shí)的虛擬，故but后面使用一般現(xiàn)在時(shí)。故D正確�？键c(diǎn)：考查時(shí)態(tài)
點(diǎn)評(píng)：本題的關(guān)鍵在于分析本句中的虛擬語(yǔ)氣所對(duì)應(yīng)的具體時(shí)間。英語(yǔ)中的時(shí)態(tài)主要由動(dòng)詞的形式?jīng)Q定，因此在學(xué)習(xí)英語(yǔ)時(shí)態(tài)時(shí)，要注意分析動(dòng)詞形式及具體語(yǔ)境，想象在那個(gè)特定的時(shí)間動(dòng)作所發(fā)生的背景，這個(gè)動(dòng)作是經(jīng)常性動(dòng)作、一般性動(dòng)作、進(jìn)行性動(dòng)作、完成性動(dòng)作還是將要發(fā)生的動(dòng)作。
