He ________ more than 5,000 English words when he entered the university at the age of 15.
A．has learnedB．would have learnedC．learnedD．had learned
D
此題容易誤選C,學(xué)生見到過去時間點(diǎn)，就會依據(jù)平時的經(jīng)驗(yàn)選擇一般過去時。其實(shí)此題應(yīng)選D。掌握了5000多個單詞并非在15歲上大學(xué)時發(fā)生，而是早在之前就完成了，過去的過去，所以要用過去完成時。此句話的漢語意思是：在他15歲上大學(xué)時，就已經(jīng)掌握了5000多個單詞了。
