句意：很抱歉，但是你一定是弄错了。
这儿没有这么个人。

故选C。
2．-- Did Jim come?-- I don’t know. He _______ while I was out.A．might have come B．might comeC．must have come D．should have come【答案】A【解析】【详解】考查情态动词推测用法。
句意：Jim来了吗？--我不知道，在我不在的时候，可能来过。
根据前文I don’t know.可知，说话者不知道Jim来没来，因此后文推测来过，但是语气很不确定，故可知选A。
对过去情况的推测为情态动词+have done，must have done 一定做了某事，should have done 应该来过，不符合，故选A。
【点睛】情态动词+have+过去分词的用法，表示推测或判断过去的情况。
can/could+have+过去分词用法：①多用于否定句和疑问句中。
表示对过去某事发生的可能性的否定或质疑，意为：不可能（已经）......了-（否定句）/可能（已经）......了嘛？-（疑问句）②用于肯定句中。
表示对过去没有做某事的遗憾，含有轻微的责备，意为：本来可以......的（但实际上没有......）。

【分析】功能：情态动词不能单独作谓语，后跟动词原形共同构成谓语。
形式：情态动词没有人称和数的变化。
否定形式是多数情态动词的否定式是在情态动词的后面加not。
时态：个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气、委婉的语气。
位置：情态动词在谓语之前；谓语动词前若有助动词，则在助动词之前。
疑问句中在主语之前。
【高频考点】1.can/could表能力、请求、可能性(表示可能性用于否定句及疑问句中)；特殊句型：can not...too.../enough(再怎么……也不过分)、can't help but do sth.(不得不做某事)、can't wait to do sth.(迫不及待地做某事)。
2.may/might表较小的可能性；表示请求许可以及祝愿。
句型和搭配：may/might as well do表示“还是……好；最好……”；may well do表示“很可能”；may可以用来表示祝愿，用“may＋主语＋动词原形”结构。
May you succeed.祝你成功。
3.must表示非常肯定的推测；表“偏要；非要……不可”；mustn't意为“禁止”，表示“不必”应用needn't。
4.shall的用法用于第二、三人称的陈述句中，表命令、警告、许诺或威胁等，语气强于should；用于第一、三人称的疑问句中，表示征询意见。
5.should/ought toshould表责任、义务、劝告、建议等，意为“应该”，还可表出乎意料的语气，意为“竟然”；ought to表义务或责任，意为“应该”。

例如：They got up early so that they should （= could/ might） catch the first bus in time.7、should 作为情态动词,可以用于下列虚拟语气句中：(1）用在表示与将来事实相反的条件状语从句中,构成“ If …… should （do sth）……, …… would/ could/ might （do sth.）…… ”句式。
(2) 用在 suggest （propose）, arrange, plan, decide, advise, order, demand, request, desire, insist 等表示“建议”、“要求”、“命令”、“决定”、“安排”、“计划”、“主张”的动词后面接的宾语从句中。
这里的 should 也可以省略。
本句中should 作为情态动词，可以用来表示意外、惊喜或者在说话人看来是不可思议的，常常译为"竟会"、"居然"，住的这么近的邻居居然不认识。
表示意外，所以答案选C。
10．The professor warned the students that on no account ________ use mobile phones in his class.A．should they B．they shouldC．dare they D．they dare【答案】A【解析】【详解】考查部分倒装和情态动词。

on no account意为“决不”，否定词放在句首，句子使用部分倒装，排除B、D项；这里表示应该，故选A。
11．—________ the woman with the baby come over? We have a seat here.—Thank you, sir. Actually I do have my seat here. But my baby likes to look out of the window. A．Would B．ShallC．Must D．May【答案】A【解析】【详解】考查情态动词。
句意：——那位抱小孩的女士，要不来这边吧?这儿有个座位。
——谢谢，实际上我有座位的，只是我的孩子喜欢看窗外。
would表示婉转的请求，征求对方的意见，Shall提问一般只用于第一人称，我们常说Shall I.或者 Shall we；may表示请求对方允许。
故选A。
【点睛】would的用法1.would 最常见的用法是：相对于一个过去时间点的后来“将要”做什么，比如：He said he would meet me at the station. 他说他会在车站接我的。
这句中的 would meet 是相对于 said （过去说）之后要做的事情。
又如：She thought she would have to ask someone for help. 她当时想，她得找个人帮忙。
