1.熟練掌握動(dòng)詞詞形變化規(guī)律。
動(dòng)詞形式既包括謂語(yǔ)動(dòng)詞的各種形式，如時(shí)態(tài)、語(yǔ)態(tài)及語(yǔ)氣(直陳、虛擬)等，虛擬語(yǔ)氣為重點(diǎn)，幾年來(lái)的考題中都有這方面內(nèi)容;也包括非謂語(yǔ)動(dòng)詞的各種形式。所以做動(dòng)詞的詞形變化時(shí)，首先要搞清楚它在句中是謂語(yǔ)動(dòng)詞還是非謂語(yǔ)動(dòng)詞，然后再作相應(yīng)的變化。
2.認(rèn)真學(xué)好并熟悉課文。
本題所選用的句子是根據(jù)教材中出現(xiàn)的句子編寫(xiě)的，其中多數(shù)來(lái)自課文，所以熟悉教材十分重要。
