Answer 1

【小題1】It is important 
【小題2】ought to
【小題3】didn’t have to
【小題4】unless… rains

解析試題分析：
【小題1】句意：早睡是對(duì)年輕人很重要的。這里是it is+形容詞+for sb to do ，it是形式主語(yǔ)，真正的主語(yǔ)是to go to sleep early ，故用It is important。 
【小題2】句意：你應(yīng)該多讀英語(yǔ)書。這里should=" ought" to “應(yīng)該”，故用ought to。
【小題3】句意：他不得不熬夜因?yàn)樗麤]有背下來(lái)新概念英語(yǔ)。因?yàn)橹^語(yǔ)動(dòng)詞是had to，變否定句的時(shí)候應(yīng)該用助動(dòng)詞didn’t 來(lái)幫助構(gòu)成，故用didn’t have to。
【小題4】句意：如果明天不下雨，我們將去登云臺(tái)山。這里if …not =" unless" ；unless引導(dǎo)的是條件從句不能用將來(lái)時(shí)而用一般現(xiàn)在時(shí)，故用unless… rains。
考點(diǎn)：句型轉(zhuǎn)換。
