Our challenge 探究任务
A club notice says, “We need a musician. We need music.” It is too vague. How can one extra clause make the message useful Explore relative clauses, then write a notice that helps the right people respond. Time: two 35-minute lessons, including the survey and notice.
G1 Observe the difference 观察差异 5 min
Compare: “I like music.” / “I like music that tells a story.” What does the second sentence tell a reader that the first does not Circle music and underline the words that describe it.
A relative clause describes a noun or pronoun before it. That word is the antecedent（先行词）. The relative pronoun（关系代词）links the description to it and has a job inside the clause.
G2 Find the noun and the extra information 寻找修饰关系 6 min
Read the examples from 4a. Brackets mark the whole description. Write person or thing, then explain what the clause helps us identify.
Example 例句 Antecedent and type 先行词及类别
I love traditional music [that / which tells a story]. music — __________
I prefer music [that / which is full of joy and celebration]. ______________________
We want to find out the kind of music [(that / which) everyone likes]. ______________________
I like musicians [who are creative]. ______________________
Move the bracketed part away from the noun it describes. Why might the sentence become harder to understand
First discovery 初步发现
In these sentences, the relative clause comes __________ the noun. It helps answer “Which one ” or “What kind ”. It is part of the noun phrase, not a separate new sentence.

The missing job 从句中缺少的成分
G3 Rebuild the two messages 还原两个句子 7 min
Compare the pairs. Replace the repeated word with a relative pronoun and join the messages. The repeated word’s job tells you whether the pronoun is a subject（主语）or an object（宾语）.
Separate messages 两个信息 Combined sentence 合并后的句子 Job 成分
I like music. The music tells a story. I like music that tells a story. subject
I like music. Everyone likes the music. I like music (that) everyone likes. ________
I like musicians. The musicians are creative. I like musicians who are creative. ________
The girl is a poet. I met the girl. The girl (who) I met is a poet. ________
G4 Test whether the link can disappear 检验能否省略 5 min
Read each sentence without the word in brackets. Is the clause still complete enough to identify the noun Explain the difference.
A. The music (that) Chris plays touches people.
B. The music (that) touches people makes Chris happy.
Check your discovery: in these defining relative clauses（限制性定语从句）, an object relative pronoun may be left out. A subject relative pronoun must stay. The test is the word’s job, not whether a person or a thing is described.
G5 Build a compact rule card 形成规则卡 3 min
Antecedent 先行词 Usual choices 本单元常用词 Omission 省略条件
A person 人 who or that May omit when it is the object.
A thing 物 which or that May omit when it is the object.
The pronoun already replaces the repeated noun. Do not add a second he, she, it or them for the same job. If the pronoun is the subject, the verb agrees with its antecedent: a musician who writes; musicians who write.

Make the meaning accurate 让意思准确
G6 Edit a club notice 修改社团通知 7 min
The following notice was written for this task. Find four grammar problems. Correct each one and name the reason: missing subject / repeated pronoun / wrong relative pronoun / verb agreement.
We need musicians who writes their own songs. Please bring music who is suitable for a school concert. We welcome the songs that you recorded them at home. We want a singer can work well with others.
G7 Use the textbook to test the rule 回到教材检验 6 min
Complete 4b in your textbook. For each new sentence, underline the antecedent and mark S or O above the relative pronoun. Put brackets around any pronoun you may omit. Explain item 2 to a partner.
Then complete 4c about Chris. Explain why the first gap is different from the gap after “a shy boy”. What can Chris do through music that he finds difficult in ordinary conversation
A useful special case: after something in 4c, use that for a thing in standard school grammar. It is an object in “something (that) Chris is good at”, so it may also be omitted in a complete sentence. Do not replace every that in English with which; first check its job.
G8 Keep the intended meaning 保留原意 4 min
Compare these two club messages. Which suggests choosing only part of the group Explain without translating every word.
A. Invite the students who play the erhu.
B. Invite the students. They play the erhu.
Now combine: “The piece is moving. We heard the piece at the concert.” State whether your relative pronoun may be omitted and why.

G9 A small preference survey 小型偏好调查 5 min
Adapt textbook 4d. Ask three classmates to rate the same two kinds of music. Use 0 = not at all, 1 = OK, 2 = like, 3 = love. Ask for a reason, not just a number.
Classmate 同学 Kind A and rating 类别A及评分 Kind B and rating 类别B及评分 Reason 理由
________ ________ ________ ________________
________ ________ ________ ________________
________ ________ ________ ________________
Report one result: “Two of the three students prefer music that … .” Do not call it the most popular music in the whole class unless the whole class took part.
G10 Write the notice 写出招募通知
Write 40–60 words for a class music club. Say which musicians you need and what music they should prepare. Use at least two relative clauses because they clarify your message, not because a longer sentence looks clever.
G11 Explain and improve 解释与改进 2 min
Exchange notices. Underline each antecedent, bracket each relative clause, and label its pronoun S or O. Ask whether any description is too vague. Revise one sentence.
Exit check 离堂自检
Finish in your own words: “I can omit the relative pronoun when … .”
A mistake I can now explain is __________________ because __________________.
If I am unsure, I will rebuild the two original sentences before choosing a pronoun.
Grammar answers 语法参考答案
Form and meaning 形式与意义
G1 and G2 The noun being described 先行词与修饰关系
The second sentence identifies the kind of music by a feature: it tells a story. The clause follows the noun. G2 antecedents: music (thing), music (thing), the kind of music / music (thing), musicians (people). The last blank is after. Moving the clause away may make its reference unclear.
G3 and G4 Subject or object 主语还是宾语
G3 missing labels: object; subject; object. In “everyone likes the music”, the music receives the action; everyone is the subject. In “the musicians are creative”, musicians is the subject.
G4 A may omit that: Chris is already the subject of plays and the music is its object. G4 B may not omit that: that is the subject of touches. Without it, the clause has no subject.
中文点拨：不要仅凭“关系词后面有人称代词”机械判断。先还原两个句子，再看关系词在从句中替代谁、充当什么成分。主句是否完整，不能决定从句关系词能否省略。
G5 The working rule 规则核对
People: who or that. Things: which or that. In the defining clauses practised here, an object relative pronoun may be omitted; a subject relative pronoun may not. Avoid a second pronoun for the same noun. Subject–verb agreement follows the antecedent.
G6 Four corrections 四处修改
1. musicians who write their own songs — musicians is plural; who is the subject.
2. music that / which is suitable — music is a thing.
3. songs (that / which) you recorded at home — remove them; the relative pronoun already represents songs as the object.
4. a singer who / that can work well with others — add the subject relative pronoun.
G7 Textbook 4b 教材合句参考
1. The song which / that uses the violin and the erhu is my favourite. (S; keep the pronoun.)
2. The girl in purple (who / that) I met at university is a gifted poet. (O; omission allowed.)
3. The policewoman who / that is standing near the concert hall will help you. (S.)
4. They are playing a beautiful piece of music which / that was written by a deaf composer. (S.)
5. George is listening to some electronic music (which / that) he downloaded last night. (O.)
Accept another grammatical sentence that preserves the original meaning. Brackets in these answers indicate optional omission, not extra punctuation required in students’ writing.

Apply and explain 应用与解释
G7 Textbook 4c 教材语境运用
In order: that; that / which; that / which; who / that; who / that. The first gap follows something, for which that is the expected school-grammar choice. The first two relative pronouns are objects and could be omitted in ordinary complete sentences, but the textbook asks students to fill the gaps.
The last three pronouns are subjects of touches, finds and enjoy; they must stay. Chris communicates feelings and connects with people through piano music even though ordinary conversation is difficult for him.
G8 Meaning before combining 先明确原意
A identifies the students who play the erhu and can select a subgroup from a larger group. B names the students as a group, then says that they play the erhu. It does not use a relative clause to select a subgroup.
The piece (that / which) we heard at the concert is moving. The relative pronoun is the object of heard; we is the subject. Omission is possible.
G9 A report with a fair limit 有边界的调查结论
Answers depend on real responses. Example: “Two of the three students prefer music that has clear lyrics. One prefers a strong rhythm. We asked only three classmates, so we cannot describe the whole class.” Compare the same categories and keep the actual ratings; do not invent a result to fit the model.
G10 A possible club notice 招募通知示例
Our class music club needs musicians who enjoy working with others. Please bring a short piece that is suitable for a school concert. We welcome songs that you have written yourself. You can also help with the programme if you do not play an instrument. Join us after class on Friday.
The first two relative pronouns are subjects; the third is an object. The notice is a classroom model, so its Friday meeting is not a claim about a real school event. Accept other useful notices of about 40–60 words.
G11 Diagnosis and next teaching step 诊断与后续教学
Observed difficulty 发现的问题 Teacher response 教师支持
The student chooses only by person or thing. Ask for the two original messages and the missing job.
The student repeats it or them. Cross out the repeated noun in the original pair first.
The student omits a subject pronoun. Read the clause alone and ask who does the action.
The grammar is correct but vague. Ask which musician or kind of music a reader can identify.
