【精析】 1. (1) 答案为hasn't, yet。现在完成时的否定句是直接在have / has后加not，另外already通常用于肯定句中。yet一般用在疑问句或否定句中。(2) 答案为How long。对for和since引导的表示一段时间的状语提问，用how long。(3) 答案为where, would。在宾语从句中，从句的语序要用陈述句的语序。从句的时态要与主句的时态一致，同时要注意人称的变化。
2. spend的用法为：(1) 主语（人） + spend + 时间或金钱 + on sth. (2) 主语（人） + spend + 时间或金钱 + in doing sth. (in有时可省略)。选A。
3. borrow表示"借入他人的东西，自己暂时使用"，构成短语borrow sth. from sb.；lend表示"把自己的东西暂时借给别人"，构成短语lend sb. sth. = lend sth. to sb.； keep指借多久，常构成短语keep sth. for + 时间。选D。
4. leave和 forget都表示"忘记"，但是它们的用法不一样。leave表示"将某物忘在某地"，构成短语leave sth.somewhere； forget表示"忘记"时，往往构成短语forget to do sth."忘记去做某事"， forget doing sth."忘记做过某事"。选B。
