be black in colour, was ten metres from the
edge of the lake during the most recent sighting.
当地的旅游办公室主任孟凡迎说, 最近有人看见怪物就在离湖边十米的地方, 怪物的颜色似乎是黑色的。句式这个句子里的which seemed to be black in colour是非限定性定语从句, 修饰先行词monster。
“主语 + seem + (to be) + 形容词/名词”是一种常见结构, 表示“某人/物看起来似乎……”。如:
The young man seems to be very excited today.
这个年轻人今天似乎很激动。2. He claims to have seen a round black creature moving quickly through the water.
他说他看见一个圆形黑色的东西在湖面快速游过。
这个句子中的to have seen是动词不定式的完成式, 表示该动作发生在谓语动词claim所表示的动作之前。【拓展】
动词不定式的形式语法情态动词may / might用法【归纳】
may / might的主要用法有：
1. may / might表示推测，意为“可能，或
许”，其中might表示的可能性较小，
含义更不确定。2. may意为“可以”，用于表示说话人同意、许可做某事。might表示过去的“允许”。
3. may / might在疑问句中用于征询对方的许可，肯定回答常用may，否定回答常用may not / mustn’t。e.g.
1) I may be late, so don’t wait for me.
2) That might be our taxi (but I am not sure).
3) The director is alone now. So you may see him now.
4) She said he might borrow her dictionary.
5) —May/Might I smoke in this room?
—Yes, you may. / No, you may not /
mustn’t.【拓展】
1. may / might表示推测时还可用进行式或完成式。如：
They may / might be waiting at the station.
They may / might have called while you were out.
2. must / could / should + have done结构
must have done表示对过去情况的肯定推测，意为“肯定做过”；could have done意为“本来能够做而没有做”；should have done意为“本来应该做而没有做”。如：
They must have gotten lost or they’d be here by now.
He could have escaped, but he chose to stand and fight.
It was an easy test and he should have passed, but he didn’t.用适当的情态动词补全下面对话。

假设你是高中生李华，你校英文报新开辟的专栏Natural Mystery正在面向广大师生征稿。请你根据所给提示信息，用英语写一篇短文应征。如何描写自然之谜注意：1. 词数100左右；2. 可适当增加细节，以使行文连贯；3. 参考词汇：物体object? 洞hole ?现象phenomenon【写作指导】
1. 审题定调：
介绍关于大自然神秘现象的短文属于说明文。这类短文通常分三个步骤来写：首先，点明这个神秘现象是什么，它有什么特征；其次，介绍科学家的解释和依据；最后，简单阐述自己对此现象的看法或者直接表明这仍然是一个未解之谜。
2. 确定主体内容：
该短文可分为三部分：
第一部分：直接点出神秘现象及发生的地点；
第二部分：具体描写该神秘现象的特征；
第三部分：科学家的相关研究情况及结论。 3. 确定人称、时态：
人称用第三人称。时态以一般现在时为主。
4. 常用表达：
a strange natural phenomenon
... is one of the world-famous mysteries.
... has been seen all over the world.
It is ... in color / shape / weight.
What makes ... so mysterious is ...Witnesses described it as ...

Ball lightning, which is very bright and usually red or orange in color, has been seen all over the world. It can usually last for several seconds or sometimes 1-2 minutes before exploding or slowly disappearing. What makes ball lightning so mysterious is its strange “behavior”. It canpass through objects. Sometimes it leaves holes, but it has also been seen to pass through objects without leaving a mark. Scientists say that ball lightning is a strange natural phenomenon that scientists still can’t fully explain. The fact that it has rarely been seen makes it difficult to study.巩固练习I. 根据括号内的提示翻译下列句子。
1. 这座大学占地100平方公里。(cover an area of ...)
The university covers an area of 100
square kilometres.2. 我不太可能接受这样的报价。 (It is likely that ...)
