About this lesson

Who it is for. Advanced students who use all standard relative clauses accurately. In formal essays they rely on that / which / who, and they make errors with more complex structures (the thing what I need, the first woman who climb, a system which by people pay, how far that it works).

Everything the lesson needs is on this page: the language analysis, the timed stages with the teacher's own words and instruction-checking questions, the differentiation, the printable handouts and the answer key.

Materials
Handout 1 (article: pioneers and innovations), Handout 2 (language analysis), Handout 3 (practice), Handout 4 (essay task and planning notes).
Preparation
About 10 minutes: print Handouts 1 to 4, one per learner, and read the language analysis. The answer key is for you, not the class.

Aims

Main aim. To develop students' use of advanced relative structures: nominal relative clauses (what, whatever, whoever), relative infinitive clauses (the first to ..., a place to stay, someone on whom to rely), connective relatives (whereby, in which case, by which time, at which point) and the extent / degree / way to which / in which.

Learning outcome. By the end of the lesson, students can write a 150-word essay paragraph about an innovation using at least six advanced relative structures, e.g. What makes mobile banking revolutionary is the system whereby payments are made instantly. The extent to which it has changed rural life is remarkable.

  • Subsidiary aim. To develop cohesion and concision in formal writing.
  • Subsidiary aim. To discuss innovation and its impact.

Language analysis

What to know before the lesson: the meaning, form and pronunciation of the target language, and the problems learners usually have with it.

Key structures

StructureFormExample
Nominal relativewhat (= the thing(s) which) + clauseWhat surprised me was the price.
whatever / whoever / wherever + clauseWhoever designed this was a genius. Take whatever you need.
Relative infinitive (after superlatives, ordinals, only, next, last)the first / last / only + noun + to-infinitiveShe was the first woman to climb Everest from Sri Lanka.
Relative infinitive (purpose / availability)noun + to-infinitive; noun + preposition + whom / which + to-infinitive (formal)a place to stay; someone on whom to rely; a reason for which to fight
Connective relativeswhereby (= by which); in which case; by which time; at which pointa system whereby users pay by phone; The bank may refuse, in which case ...
Degree / mannerthe extent / degree to which; the way in whichThe extent to which this helped is unclear.

Accuracy notes

  • what is not used after a noun: the thing what I need ✗ → the thing (that) I need or what I need.
  • After the first / the only, use the infinitive, not a full clause with the wrong tense: the first person to land (or who landed).
  • whereby is formal and refers to a system, method or arrangement.

Pronunciation

  • Nominal relatives used as subjects are often followed by a pause in speech: What surprised me | was the price.

Concept-checking questions

  • What surprised me was the price. What does what mean here? (The thing that.) · What was surprising? (The price.)
  • a system whereby users pay by phone What does whereby mean? (By which / through which.) · Is it formal or informal? (Formal.)
  • She was the first Sri Lankan woman to climb Everest. Did she climb Everest? (Yes.) · Had any Sri Lankan woman done it before? (No.)

CEFR C1 · 60 minutes · Teenagers and adults

Procedure: Advanced Relative Structures, step by step

Warm-up5 minutes · Pairs, then whole class

Aim: To introduce the topic and engage students.

Ask: "Which invention of the last 30 years has changed life most in your country? Why?"

Pairs discuss (2 minutes). Take two or three ideas and board one sentence exactly as a student says it.

Presentation20 minutes · Individual, groups, whole class

Aim: To present advanced relative structures in an article and clarify their form, meaning and function.

Part A: Reading (5 minutes)

Give out Handout 1. Say: "Read the article. Which pioneer do you find most inspiring? Why?"

Pairs compare.

Part B: Analysis (7 minutes)

Give out Handout 2. Say: "In groups, find the structures in the article and complete the table. Then answer the questions."

ICQs: "How many structures do you find?" (Eight.) "Where?" (In the article.)

Monitor and help.

Part C: Clarification (8 minutes)

Feedback. Build the patterns in the centre of the board.

Nominal relatives. Board What surprised me was the price. Ask the CCQs. Board the thing what ✗. Show how what ... was gives emphasis.

Relative infinitives. Board the first Sri Lankan woman to climb Everest and someone on whom to rely. Ask the CCQs.

Connective relatives. Board a system whereby users pay by phone and The bank may refuse, in which case ... Ask the CCQs.

Degree. Board The extent to which mobile banking has helped farmers is remarkable.

Return to the student's sentence from Stage 1 and improve it with one structure.

Controlled practice10 minutes · Individual, then pairs, then whole class

Aim: To practise the structures accurately.

Give out Handout 3. Say: "Exercise A: rewrite each sentence using the word given. Exercise B: correct the errors. Seven minutes."

Pairs check. Check as a class.

Freer practice18 minutes · Pairs, then groups of four, then whole class

Aim: To use the structures in a formal essay paragraph.

Give out Handout 4. Pairs choose one innovation from the notes (or their own) and write a 150-word essay paragraph evaluating its impact. They must use at least six structures from today (11 minutes).

ICQs: "How many structures?" (At least six.) "Do you describe or evaluate?" (Evaluate the impact.)

Two pairs join, read each other's paragraphs and underline the structures. They choose one sentence that could be more concise and rewrite it (4 minutes).

Two groups read their best sentences aloud (3 minutes).

Monitor and note language use.

Feedback and wrap-up7 minutes · Whole class

Aim: To give feedback and consolidate.

Board strong sentences and two or three with errors. Students correct the errors.

Ask: "Which structure adds emphasis? Which makes writing more concise?"

Set the homework.

Homework Write a 250-word essay: Which innovation has had the greatest impact on your country? Use at least eight advanced relative structures.

PPP (presentation, practice, production). Stage times add up to 60 minutes.

Differentiation

Support
Give weaker students a pattern card with examples. Provide sentence starters: What makes ... important is ... · ... was the first ... to ... · ... is a system whereby ...
Stretch
Stronger students use all of which, none of whom, the result of which and in the course of which. They combine structures: What remains unclear is the extent to which ...

Adapting the lesson

ForWhat to change
A large class (40 or more)Keep the pairwork in "Freer practice" in fixed pairs rather than a mingle, and take feedback from four or five pairs instead of the whole room. Monitor one half of the room during "Controlled practice" and the other half during "Freer practice".
A class with no photocopierPut the exercises from Handout 3: Practice on the board for learners to copy into their notebooks, and read any text aloud twice instead of printing it. The board plan above is this lesson's minimum - with that on the board, it runs on no paper at all.
An online classSend Handouts 1 to 4 in the chat before the lesson and put the board plan on a shared slide. Use breakout rooms for the pairwork in "Freer practice" and visit each room once. Have learners type the controlled answers in the chat, so you see every answer at once instead of nominating.
A different age groupWith teenagers at this level, cut the academic framing and keep the examples in their own world; the forms do not change. With adults in a work context, swap the lesson's texts for ones from their own field and keep the analysis as it stands.

Checking learning

The paragraph uses at least six advanced relative structures accurately. No the thing what or incorrect whereby errors. 7 out of 8 or better on Handout 3, Exercise A.

Teacher's reflection

Which structures did students use most naturally? Did the writing become more concise and cohesive?

Handout 1: Pioneers and Innovations

Name: ______________________________ Date: ______________

SMALL IDEAS, BIG CHANGES

What makes an innovation truly important is not its complexity but the extent to which it changes ordinary lives. Consider mobile money, a system whereby people send and receive payments using a basic phone. In rural areas, where banks are often hours away, it has become a lifeline. Whoever has a phone can now pay school fees, receive wages and save, which was unimaginable twenty years ago.

Another example is solar lanterns. For families with no electricity, there was often no safe way in which children could study after dark. Today, a lantern costing less than a pair of shoes gives them light to read by.

Pioneers matter too. In 2016, Jayanthi Kuru-Utumpala became the first Sri Lankan to climb Mount Everest. It was a climb on which there was no one on whom to rely but her team. She spent weeks acclimatising, by which time several climbers had already turned back.

What these stories show is that innovation is about access: giving people whatever they need to take control of their own lives. If the technology is too expensive, it will fail, in which case even the best idea changes nothing.

Handout 2: Language Analysis

Name: ______________________________ Date: ______________

Find an example of each structure in the article.

Discuss.

  • Rewrite What makes an innovation truly important is ... without what. Which version is more emphatic? ______________________________
  • What does whereby mean? Could you use where instead? ______________________________
  • light to read by: what is the full relative clause? ______________________________
StructureExample from the article
what + clause as subject
the extent to which
whereby
whoever / whatever
the way in which
the first + noun + to-infinitive
preposition + whom + to-infinitive
by which time / in which case

Handout 3: Practice

Name: ______________________________ Date: ______________

A. Rewrite each sentence using the word given. Keep the meaning the same.

B. Correct the errors.

  • The thing that worries me is the cost. (What) → ______________________________
  • Anyone who finds the keys should take them to reception. (Whoever) → ______________________________
  • She was the first woman who won the prize. (to) → ______________________________
  • Under the new system, students pay by phone. (whereby) → There is a new system ______________________________
  • It is not clear how much the scheme has helped farmers. (extent) → The extent ______________________________
  • You may lose your ticket. If so, you must buy a new one. (in which case) → You may lose your ticket, ______________________________
  • We arrived at 10. The film had already started. (by which time) → We arrived at 10, ______________________________
  • I need someone I can rely on. (whom) → I need someone ______________________________
  • The thing what I need is more time. ______________________________
  • He was the only player who score twice. ______________________________
  • This is a hotel whereby you can see the sea. ______________________________
  • Whatever told you that was wrong. ______________________________
  • The extent which it worked is unclear. ______________________________
