Language points
However, these days, something unusual is happening in our town. 然而，最近，我们城镇发生了一件怪事。
形容词修饰 something 等不定代词时，形容词须后置。
※ There’s something wrong with the TV.
电视出毛病了。
unusual 作形容词，意为“不寻常的”，是 usual 的反义词。
※ It is unusual that winter comes so early this year.
今年的冬天来得这么早，这不正常。
2. Maybe it was a bear or a wolf. 或许它是一头熊或一只狼。
maybe 在此作副词，意为“也许；可能”，在句中作状语，相当于 perhaps，常位于句首。may be 意为“也许是；可能是”，may 是情态动词，be 是动词原形，两者构成完整的谓语形式，与主语形成系表结构，和 maybe可相互转换。
※ Maybe you are right. =
You may be right.
你或许是对的。
3. There must be something visiting the homes in our
neighborhood, but what is it？
肯定有什么东西闯入了我们的社区，但它是什么呢？
情态动态 must 用在 there be 句型中，表示推测，意为“一定有……”。“there must be+主语+doing sth.”意为“一定有某人/物正在做某事”。Visiting the homes 是现在分词短语作定语。
※ Look！There are some policemen. I think there must be a traffic accident. 看，有一些警察。我想肯定发生交通事故了。
4. Most people hope that this animal or person will simply go away, but I do not think that is going to happen.
大多数人希望这只动物或这个人会自己消失，但是我认为这种事情不会发生。
hope 作及物动词，后接 that 从句，意为“希望……”。
※ I hope（that）I can pass the exam.
我希望我能通过考试。

情态动词中的 must、can、could、may、might 都表推测。其中 must 的可能性最大，can/could 次之，
may/might 最小。
Grammer points
must 表示推测“可能性”时，意为“一定；准是”，语气较肯定，较有把握。“must+动词原形”表示对现在情况较有把握的推测，意为“一定”；“must have+动词的过去分词”表示对过去情况较有把握的推测，意为“一定已经”。
※ Mr. Li must be working now, for the lights in his office are
still on.
李先生一定在工作，因为他办公室的灯仍然亮着。
must 的用法
must 表推测只能用于肯定句。mustn’t 表示“禁止；不准”。如果要表示“一定不；肯定不”的意思，应用 can’t。
※ You mustn’t play outside when it is raining.
下雨时，不准在外面玩。
can 表示推测“可能性”时，往往用于否定句或疑问句。
※ He can’t be at home.
=It is impossible that he is at home.
他不可能在家。
could 可用于表示某事有可能发生或可能是事实，语气不
是很肯定。
※ Don’t eat it. It could be poisonous.
不要吃它，它可能有毒。
can 和 could 的用法
couldn’t 用于否定推测，表示某事不可能是事实，但自己也不能肯定。
※ It couldn’t possibly be Tom, for he should be at school now.
这不可能是汤姆，因为此时他应该在学校。
may/might 表示推测“可能性”时，意为“可能，也许”，语气没有 must 肯定。
※ He may/might be an American.
=It is possible that he is an American.
他可能是个美国人。
may 和 might 的用法
may/might 表推测时，可以用于否定句，意为“可能
不，也许不”，但不用于疑问句。
※ He may/might not be at home, but I am not sure.
他也许不在家，但我不确定。
表示推测时，may not 意为“可能不”，can’t 意为
“不可能”，前者较后者语气弱得多。
