【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 卻宜用一般現在時，因為 I don’t know 表述的是現在的真實情況，句意為“我要不是有幸遇到你，我真不知(指現在不知)我會做出什么蠢事來”。

3. 選B。I’d rather 后接從句時，從句謂語的時態規律是：用過去式表示現在或將來，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，故宜用陳述語氣。

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

6. 選C。It’s time… / It’s high time… / It’s about time… 等后接從句時，從句謂語通常用過去式。

7. 選 B。此題涉及錯綜時間虛擬條件句，主句與現在事實相反，條件句與過去事實相反。句意為：要不是在七歲時就迷上了 Melinda Cox 圖書館，我真不能想像我如今會在做什么。

8. 選 D。這是otherwise 引出的含蓄虛擬語氣，再根據前面的 hesitated 可進一步知道這是與過去事實相反的虛擬語氣，由此可推知答案選 D。(m.52ysedu.com)

9. 選 C。if only 意為“要是……就好了”，其后的句子謂語要用虛擬語氣，同時根據 as the doctor instructed 中的過去時態可知從句是與過去事實相反，故選 C。

10. 選 A。without 引出的介詞短語為一個與現在事實相反的含蓄條件句。

11. 選 D。otherwise 在此相當于 if she had not walked away from the discussion，即暗示一個與過去事實相反的虛擬條件句。
