📌 How to use this lesson

For Teachers:

Guide learners through the 4-row rule matrix first, setting a 12-minute target for completion. Have students verify their answers independently using the automated feedback key.

For Learners:

Read the four pattern rules in the reference table carefully before starting the tasks. Next, complete all 12 exercise cards below to practise this word order.

Grammar Pattern Matrix: Inversion for Emphasis

Study how word order changes to create strong dramatic effect.

So + Adjective

Put the describing word first to make it strong. Then put the verb before the subject, followed by a that-clause.

• So narrow is the trench that the robotic arm could not enter.

• So heavy is the cable that two cranes are needed to lift it.

Such + Noun Phrase

Use such when the next idea is a thing, like "the size of the crowd". Then put was or is next, then the thing. Do not use "so" here.

• Such was the pressure of the sediment that the steel hull bent.

• Such is the cost of one deep dive that few companies can pay for it.

So + Adverb

Put how an action happens at the start. Then use a helper word like did, does, or do before the subject, as in a question.

• So slowly did the sample rise that it cooled on the way up.

• So carefully did the crew lower the probe that nothing was damaged.

So much / many / little / few

These amount words sit right with the subject. The sentence keeps its normal word order without swapping words around.

• So little is known about the uncharted area that each new map is a surprise.

• So few people have seen the deepest seabed that every photograph is news.
