新概念英语第二册课后题答案详解：Lesson661. c根据课文第6-7行By this time, a Lancaster bomber in reasonable condition was rare and worth rescuing 能够判断只有c. it was a rare model (它是一个罕见的型号)是人们对修复这架飞机感兴趣的原因。
其他3个选择虽然是课文提及的情况，但都不是原因。
2. b根据课文最后一句A colony of bees had turned the engine into hive and it was totally preserved in beeswax! 能够看出只有b. A colony of bees(一群蜜蜂)保护了其中的一台发动机，所以b.是准确答案。
其他3个选择都与课文实际内容不符合。
3. a前一句中的west of Samoa 意思为萨摩亚群岛以西，本句需要选一个同这个短语意思相同的短语。
a. to the west of Samoa (在萨摩亚群岛之西)指不在这个岛上;b. to the east of Samoa (在萨摩亚群岛之东);c. in the west Samoa (在萨摩亚群岛的西部)，指在这个群岛上;d. in the east of Samoa (在萨摩亚群岛的东部). 只有a. 与前一句含义相同，所以选a.4. a前句中的undisturbed 意思是“没有受到打搅”，本句应该选一个同这个词含义相反的词。
a. moved(移动);b. damaged(损害，损伤);c. packaged(把……打包);d. restored (修复)中，只有a. moved 同undisturbed意思相反，而后一句是否定句，这样一来，前后两句的意思就一致了。
所以选a.5. d该句中的worth (值……的)是形容词，它后面只能跟动名词或名词，只有d. saving 是动名词，最合乎语法，所以选d. 其他3个选择都不合乎语法。

新概念英语第⼆册课后习题答案详解Lesson 67 1. d 根据课⽂第2-3⾏ In 1984, he went to lake Kivu in the Congo to observe a new volcano which 可以看出只有d. to investigate a new volcano (调查⼀座新⽕⼭)与课⽂的内容相符，其他3个选择都与课⽂的实际情况不符，所以选d. 2. a 根据课⽂第9-10⾏…but Tazieff managed to escape…He waited until the volcano became quiet and he was able to return two days later 可以判断，只有a. and Tazieff had to leave but he returned later 与课⽂的实际情况相符，其他3个选择都与课⽂的实际情况不符，所以选a. 3. /xgn/2856.html 前⼀句中的managed to 表⽰“成功地完成了的动作”，本句需要对这⼀动词作解释说明。
a. might have taken (本来应该做)；b. could have taken (本来可以做)；c. should have taken (本应该做)；这3个选择含义相同都表⽰“过去该做，但却没做”，与managed to 含义不同。
只有d. succeeded in taking 与 managed to 意思相同，所以选d. 4. d 前⼀句he escaped just in time 意思为“他刚好及时逃离了。
”句中的just 是表⽰强调语⽓的副词，它的含义是“正好”，“勉强地”，本句是对前⼀句的进⼀步解释。
a. just only 的意思不通；b. only (只是，仅仅)与前⼀句含义不符；c. soon (不久，很快)与前⼀句意思不符；只有d. only just (只是勉强地)与前⼀句含义相符，所以选d. 5. d 该句的动词waited(等待)是不及物动词，后⾯只能跟for引导的短语。

Now a group of enthusiasts are going to have the plane restored. It has four Rolls-Royce Merlin engines, but the group will need to have only three of them rebuilt. Imagine their surprise and delight when they broke open the packing cases and found that the fourth engine was sweet as honey — still in perfect condition.
