（通过练习导入主题）
Step2: To know the usage of it as an empty object
Activity 1: Look at the sentences and answer the questions. Sentence (a) and (c) are from the reading passage.
a. No visitor would think it surprising that the island is a UNESCO World Heritage Site. b. No visitor would think that island being a UNESCO World Heritage Site is surprising.
c. Experts felt it necessary to come up with a plan to remove all the rabbits from the island. d. Experts felt to come up with a plan to remove all the rabbits from the island was necessary.
1 What does “it” refer to in the sentences (a) and (c)
2 What is the difference between the sentences in each group
Answers:
1 “It” in sentence (a) refers to “the island is a UNESCO World Heritage Site”
“It” in sentence (c) refers to “to come up with a plan to remove all the rabbits from the island”
2 When the object of a sentence is a that-clause (b) or an infinitive (d), we sometimes use “it” as an empty object and put the real object later to keep balance. For example, sentence (a) uses “it” as the empty object of “think”, referring to the real object: “the island is a UNESCO World Heritage Site”. Sentence (b) uses that-clause as the object of “think”.
Now look for more sentences with this structure in the reading passage, and summarise its uses in your own words.
This incident made it clear that rat, mouse and rabbit problem needed solving once and for all.
...
Activity 2: Read the following sentences and summarise what can be used it as an empty object.
1 They felt it difficult to finish the work in such a short time.
2 He thought it useless attempting the impossible.
3 I took it for granted that they would not come.

我发现，可以用it作形式宾语替代的成分有：______________，______________，______________。
Answers: 不定式；动名词；从句
当不定式、动名词或从句在某个句子中做宾语时，为了保持句子的结构平衡，常用it作为形式宾语，而将真正的宾语放到句子的后部去。
【语法精讲】
1 it作为形式宾语可以分为两种情况：
代表不定式。
例如： I don’t feel it difficult to understand the passage.
代表连接代词或连接副词引导的从句或动名词。
例如：He hasn’t made it clear when he is coming back.
The professor considers it no good reading without understanding.
2 几种特殊情况
1）动词+ it + that从句，常见于take，have，put等动词之后。例如：I take it that he will finish the task by himself.（我认为他能自己完成这项任务。）
2）动词+ it + when/if从句，常见于 appreciate，enjoy，like，prefer 等词之后。例如：We really appreciate it if you could do us a favour.（如果您能帮助我，我们会很感激。）
3）动词+ it +介词短语+ that从句，常见于owe it to sb，take it for granted 等结构中。例如：We owe it to you that we are still alive.（多有你，我们现在才仍然活着。）
4）动词+介词+ it + that从句，常见于look to，depend on，insist on，stick to，answer for 等结构中。例如：She insisted on it that she was innocent.（她坚持说自己是无辜的。）
5）动词+ it+过去分词+从句。例如：He made it known to everyone that he was right.（他让每个人都明白他是对的。）

教学反思：
这节课围绕“Unit5 A Delicate World Using language"展开，从学生的反馈来看，整体教学效果较好。以下是我对这节课的反思:
在设计课程时，我充分考虑了学生的实际情况，以激发他们的学习兴趣为出发点。通过导入环节的问题，成功引起了学生的兴趣，让他们迅速进入学习状态。在今后的教学中，我需要更加精准地把握学生的兴趣点，以便更好地吸引他们的注意力。
在课堂讲解环节，我发现学生对特殊结构的理解较为困难，因此，我在讲解时特意放慢了速度，做了详细解释。从学生的反应来看，他们对此部分内容的掌握程度还可以。在实践活动环节，学生的参与度较高，他们能够积极地参与到小组讨论中，这让我感到欣慰，说明学生在课堂上能够将所学知识应用到实际情境中。在小组讨论环节，学生能够从不同角度分析问题，提出解决方案。这表明他们在思考问题。
