1. He likes reading. Now he be reading in the library.
2. The ground is all wet. It have rained last night.
3. —Listen! Is Tom singing in the classroom?
—No. It be Tom. He has gone to Paris.

1. might
2. must
3. can't

【分析】本题考查情态动词表推测的用法，解题时需结合句子给出的线索判断推测的可能性程度：第1题中“他喜欢阅读”，现在在图书馆读书是一种可能性较低的推测，用might；第2题地面全湿是昨晚下雨的明显证据，是肯定的推测，用must；第3题Tom去了巴黎，所以是不可能的推测，用can't。
【解析】1. 由“He likes reading”可知，他现在在图书馆读书是一种可能的情况，可能性不是100%，故填might；2. “The ground is all wet”是昨晚下雨的直接证据，推测是肯定的，故填must；3. 由“He has gone to Paris”可知，不可能是Tom在唱歌，故填can't。
【答案】1. might 2. must 3. can't
【知识点】情态动词表推测
【点评】本题围绕情态动词表推测的核心考点，结合具体语境判断推测的可能性，属于基础语法题，需掌握不同情态动词表推测的用法差异。
【难度系数】0.5

【分析】
本题分为两部分，第一部分考查情态动词表推测的用法，需明确肯定推测与否定推测的不同表达规则；第二部分为语法填空，需结合时间状语、主谓关系、固定搭配等知识点确定单词的正确形式。解题时先梳理情态动词表推测的核心用法，再逐一分析语法填空的语境与语法要求。
【解析】
1. 第一题：情态动词表推测时，肯定推测用“must + be/动词原形”，否定推测需用“can't + be/动词原形”（表示“不可能”），因此原句的must be改为can't be。
2. 第二题：前句“你一整天都努力工作了”是对现在情况的依据，需用肯定推测，结构为“must + be/动词原形”，故填must be。
回归教材部分：
1. 时间状语every year提示用一般现在时，主语the Sanxingdui Museum是第三人称单数，谓语动词用attracts。
2. 固定搭配be surprised by意为“对……感到惊讶”，will后接动词原形，故填be surprised。
3. 时间状语more than 3,000 years ago提示用一般过去时，live的过去式为lived。
4. 固定搭配not...until...意为“直到……才……”，符合句意，故填until。
5. 主语objects与find是被动关系，且动作发生在过去，用一般过去时的被动语态were found。
6. 谓语为were，主语需用复数名词，discovery的复数为discoveries。
7. 介词With表示“借助、用”，符合句意，故填With。
8. must have been是对过去情况的肯定推测，结构正确，故填have been。
9. one of后接形容词最高级，great的最高级为greatest。
10. 时间状语now提示用现在进行时，主语it是第三人称单数，故填is looking。
【答案】
1. can't be
2. must be
