这篇文档是针对高中英语Module3 Foreign Food Section Ⅱ Grammar的部分课时作业，涉及的是外研版选修8的内容。作业主要包含两大部分：动词的适当形式填空和关系词填空，以及一些单句改错题。下面将详细解析这些语法知识点。
**I. 动词的适当形式填空**
这部分练习主要考察学生对动词时态、非谓语动词（动词的现在分词、过去分词和不定式）以及动词短语的理解和运用。
1. "Chewing your food thoroughly, you'll have a healthy stomach."
- "Chewing"在这里是非谓语动词，作条件状语，表示主动且与主句主语"you"一致，所以用现在分词形式。
2. "‘It's getting warmer and warmer,’ he remarked."
- "remarked"是谓语动词，表示过去发生的动作。
3. "The grilled mutton is very delicious."
- "grilled"是过去分词作定语，修饰"mutton"，表示被动完成的动作。
4. "There are some people dreaming about flying like a bird."
- "dreaming"是现在分词作定语，表示主动进行的状态。
5. "A dish containing a lot of vegetables is always popular with the old."
- "containing"是现在分词作后置定语，修饰"dish"，表示主动状态。
6. "The emails to be written will be finished by 9:00 this evening."
- "to be written"是不定式作定语，表示将来的被动动作。
7. "He bought a TV set made in that factory."
- "made"是过去分词作定语，表示被动完成的动作。
8. "She will join in the singing competition of the city."
- "singing"是现在分词作定语，修饰"competition"，表示动作的性质。
9. "The teacher shows us many grammar rules to follow."
- "to follow"是不定式作定语，表示目的。
10. "The desk is used to draw pictures on."
- "to draw"是不定式作目的状语，表示"用来做..."。
**II. 关系词填空**
这部分练习考察了关系代词和关系副词的使用，如"which", "who", "whose", "where", "that", "why", "as", "whom"和"when"等，它们在定语从句中起连接作用。
1. "... many of which are caused by human error."
- "which"指代"accidents"，在定语从句中作主语。
2. "Some people who are successful language learners often fail in other fields."
- "who"引导定语从句，修饰"people"，在从句中作主语。
3. "In our class, we have some students whose families are not in Wuhan."
- "whose"引导定语从句，修饰"students"，在从句中作定语。
4. "Tell him to go to the classroom where we often have our English class."
- "where"引导地点状语从句，表示地点。
5. "That is the only way that leads to your success."
- "that"在此处是关系代词，代替"way"，在从句中作主语。
6. "The reason why she was late is not acceptable."
- "why"引导原因状语从句，表示原因。
7. "Professor Li is extremely popular among students, as is known to all of us."
- "as"引导非限制性定语从句，指代整个主句内容。
8. "The secretary with whom the boss is not happy will be fired."
- "whom"引导定语从句，修饰"secretary"，在从句中作介词"with"的宾语。
9. "The day when I met the famous pop star was the greatest day of my life."
- "when"引导时间状语从句，表示时间。
**III. 单句改错**
这部分主要检查学生对句子结构和语法规范的理解。
1. "This is the factory where we visited last week."
- 错误在于关系词使用不当，应改为"This is the factory that/which we visited last week."。
2. "This is the watch for which Tom is looking."
- 此句中"for which"引导的定语从句不恰当，应改为"This is the watch Tom is looking for."。
3. "The person to who you spoke is a student of Grade Two."
- "who"前的介词"to"应该去掉，改为"The person you spoke to is a student of Grade Two."
4. "The house in that we live is very small."
- "that"不能引导介词后的定语从句，应改为"The house in which we live is very small."或"The house where we live is very small."
这些题目和解析涵盖了英语语法中的多个核心概念，包括动词的非谓语形式、定语从句和状语从句的引导词选择，以及句子结构的修正。通过这样的练习，学生可以深化对英语语法的理解，并提升实际应用能力。
