　　【答案與解析】

　　1. 選B,。It’s time you did 為 It’s time you thanked Aunt Lucy for her present 之略。按照英語語法,，it’s time 后從句通常要用過去式,。

　　2. 選A。雖然前有虛擬條件句, 后有使用了虛擬語氣的賓語,，但 I don’t know 卻宜用一般現(xiàn)在時(shí),，因?yàn)?I don’t know 表述的是現(xiàn)在的真實(shí)情況，句意為“我要不是有幸遇到你,，我真不知(指現(xiàn)在不知)我會(huì)做出什么蠢事來”,。

　　3. 選B。I’d rather 后接從句時(shí),，從句謂語的時(shí)態(tài)規(guī)律是：用過去式表示現(xiàn)在或?qū)?，用過去完成式表示過去。

　　4. 選A,。we can’t get there by tomorrow 為客觀事實(shí),，故宜用陳述語氣。

　　5. 選B,。第一空填 knew,，因?yàn)?I wish 后的賓語從句要用虛擬語氣(即用過去式表示現(xiàn)在的想法)；第二空要填lives,，即用陳述語氣,，因?yàn)?where he lives 是一個(gè)客觀事實(shí)，而不是 I wish 的內(nèi)容,。
