1． b根据课文的实际内容,可以推断只有ｂ．ｈａd ｆｏｕnd Ｓａm’ｓwallet anｄkepｔｉｔ是课文暗示的真实情况。
ａ. haｄｓtolen Saｍ’sｗaｌｌｅt 不够确切,因为课文中的意思是Ｓam waｓsure ｔｈaｔtｈｅｗalｌｅt mｕｓt have been founｄｂy onｅo ｆthe vilｌagerｓ(山姆确信那钱包是被某个村民捡到了，而不是偷走了)；ｃ. hａｄlosｔＳａm’ｓwａllet 与课文的意思相反;ｄ. had tａkeｎｔｈe waｌle ｔfroｍSａm’sｐｏcｋeｔ不是课文提及的内容。
2. ｄ根据课文所描述的情况，只有ｄ. returｎeｄaｌl tｈe mｏney 与课文事实相符,其他3个选择都与事实不符。
3． aa. when,b. wｈile，ｃ. as 和ｄ. just ａｓ都可以做连词，引导时间从句,表示“当……时”,本句只能选a.在前半句是过去进行时，后半句是一般过去时的情况下,中间多用when,表示两个动作同时发生，“正当……时”，而后３个选择引导的时间从句大都是进行时态。
4. ｂ本句只有选b. in 意思才讲得通。
Ｈｅkeｅpｓｈis ｓａｖings in tｈe ｐｏst offｉce.(他把存款放在邮局保管)。
本句中的动词keep(存放，保管）不是表示“去向”的，所以不能选ａ. to (到)和d. iｎtｏ(进入),ｃ. on （在……上面)也不合乎题目意思，不能用on the pｏｓｔoffice．而应该是ｉｎｔhe posｔoffiｃe.（在邮局里),所以选b.5. b本句是一个被动语态句。
只有b. by 表示“被”的意思，最符合语法和题目意思。
ａ. ｆrｏm ， c. ｏuｔof, ｄ．of 都没有“被”的意思，所以都不对。
6．ｄ本句是一个特殊疑问句,针对介词in的宾语提问的,回答是Ａｎeｗspａpｅｒ. a. wｈerｅ是询问地点的；ｂ．who 是针对主语（人）提问的;ｃ. ｈow 是询问状态。
裕兴新概念英语第二册笔记_第45课_课文讲解Text The whole village soon learnt that a large sum of money had been lost. that 引导宾语从句。
从句 a large sum of money had been lost.使用了被动语态，还原为主动语态为：someone had lost a large sum of money.a large sum of money 一大笔钱a small sum of money 一笔小钱egHe paid an enormous sum for the painting by Turner. 他花了一大笔钱买透纳的画。
Sam Benton, the local butcher, had lost his wallet while taking his savings to the post office. butcher ['but??] 1n 屠夫；肉商the butcher’s 肉铺，肉店2v 屠杀（动物），残杀（人）while 引导的从句主语与主句主语相同，故可省略。
原句应为：while he was taking his savings to the post office Sam was sure that the wallet must have been found by one of the villagers, but it was not returned to him. must have been found 表示对已发生的事一种判断,而且是被动形式。
must have +过去分词，表示对过去动作的猜测，表示一定做过了，未说明具体时间；Three months passed, and then one morning, Sam found his wallet outside his front door. find his wallet outside find + n+ adj 发现….为…..egI found my cat asleep in my bed. 我发现我的猫在我的床上睡着了。

clear在这里的含义为"清白的"、"无罪的"，因此这个短语又可译为"清白的良心"，相当于a good conscience，反义词为a bad conscience（感到内疚）。

taking为现在分词。
与动名词相似，它也可以有自己的宾语、状语等。
在连词while之后，现在分词短语的作用相当于一个时间状语从句：…while he was taking his savings to the post office。
现在分词这样用的前提是两个动词的主语是同一个，并且这两个动作通常是同时发生的：He listened to music while cleaning the room.他一边打扫房间一边听音乐。

新概念英语第二册课后练习题答案详解(第45课)新概念英语第二册课后习题Lesson 451. b根据课文的实际内容，能够推断只有b. had found Sam’swallet and kept it 是课文暗示的真实情况。
a. had stolenSam’s wallet 不够确切，因为课文中的意思是Sam was sure that the wallet must have been found by one of the villagers (山姆确信那钱包是被某个村民捡到了，而不是偷走了);c. had lostSam’s wallet 与课文的意思相反;d. had taken the wallet from Sam’s pocket 不是课文提及的内容。

4. b本句只有选b. in 意思才讲得通。
