E9 E - Complex sentence choices for clear writing

Mini-Beschreibung: Decide when complex sentences, relative clauses and adverbial clauses make a text more precise – and when shorter sentences make it easier to understand. You work at E9-E level: independently, with authentic-style material, source checks, discussion, revision and transfer.

Target group: English as a first foreign language, Grade 9, E-Niveau, Baden-Württemberg.

Learning loop: English first → understand → respond → ask → hint → improve → use again. Du arbeitest möglichst zuerst auf Englisch. Deutsche Hinweise helfen punktuell, aber ersetzen keine Vollübersetzung.

Media starter: Which version is clearer?

Read both versions aloud.

Version A: The post looked convincing. It used a graph. The graph had no source. I did not share the post.

Version B: Although the post looked convincing because it used a graph, I did not share it because the graph had no source.

Quick decision: Which version would you use in a school article? Which one in a warning message? Give one reason.

Key idea: A complex sentence is useful when the relationship between ideas matters. A shorter sentence is useful when the reader needs speed, emphasis or a lower processing load.

Viewing task: Watch the Khan Academy video. Note one example of an independent clause and one dependent clause. Then explain the difference in your own English words.

I-can goals

After this aiMOOC, you can say:

I can identify independent and dependent clauses in longer sentences.
I can explain what information a relative clause adds.
I can explain the relationship shown by an adverbial clause.
I can choose between a complex sentence and two shorter sentences for a clear purpose.
I can revise my own writing for precision, rhythm and readability.
I can compare perspectives and source quality before I use information.
I can give and use focused feedback without replacing my own text.
I can mediate information for a specific reader instead of translating everything.

Prior knowledge check

Try this without notes.

A. Clause check

In I checked the source because the claim surprised me, underline the part that can stand alone.
In The video that we watched was short, circle the word that introduces the relative clause.
Turn The headline was dramatic. I read the full article. into one sentence that shows contrast.

B. Self-check

If this is difficult, use the first hint only. If you can already do it, skip ahead to the revision challenge.

Hint 1: An independent clause can stand as a complete sentence.

Hint 2: Relative clauses often begin with who, which, that, whose or where.

Hint 3: Adverbial clauses often show relationships such as reason, contrast, time or condition.

Core grammar for real writing

Complex sentence = relationship made visible

A complex sentence contains one independent clause and at least one dependent clause.

Example: Although the photo looked authentic, Mia checked the source.

Independent clause: Mia checked the source.
Dependent adverbial clause: Although the photo looked authentic
Function: the sentence makes the contrast explicit.

A longer sentence is not automatically better. Use complexity only when it helps the reader see a meaningful relationship.

Relative clauses = precise noun information

A relative clause adds information about a noun.

Defining: The article that includes the original data is more useful.

The clause identifies which article you mean.

Non-defining: The school podcast, which started last year, now has a new team.

The clause adds extra information. In standard written English, non-defining relative clauses are set off by commas.

Viewing task: Listen for who, which, that and where. Make a four-column note: connector | noun | extra information | essential or extra.

Adverbial clauses = logic between ideas

An adverbial clause can show:

reason: because, since
contrast: although, even though, while
time: when, after, before, while
condition: if, unless
purpose: so that

Examples:

Because the source named its author, we could check the writer's background.

Although the clip was popular, the class checked when it had been recorded.

If a sentence carries too many ideas, split it.

Listening task: Choose three conjunctions from the video. For each one, state the relationship it signals and create one school-related example.

Short sentences = clarity, pace and emphasis

Shorter sentences can be better when:

the reader needs a key point fast;
a sentence contains too many layers;
you want emphasis;
the logical connection is already clear from the context;
a complex structure makes the reader reread.

Compare:

The survey, which was shared by the media team after the class had discussed the project because several students had asked for more choice, received 84 replies.

Clearer revision:

The media team shared the survey after the class discussion. It received 84 replies because many students wanted more choice.

The revision is not “simpler thinking”. It separates information so the reader can process it.

The clarity decision

Use this quick test when you revise.

Ask yourself	If yes	If no
Does the relationship between ideas matter?	Join ideas with a precise clause.	Shorter sentences may be enough.
Does a relative clause identify or usefully add information about a noun?	Keep it.	Remove it or move the detail.
Can the reader follow the sentence once, without rereading?	The structure may work.	Split, reorder or reduce it.
Does the sentence contain several because/which/that/although layers?	Check whether every layer is needed.	Keep the structure if it is clear.
Do you want strong emphasis?	Consider a short sentence.	A complex sentence may show nuance better.

Rule of thumb: Choose the sentence shape that helps your reader understand the exact meaning with the least unnecessary effort.

Listening and Viewing

Viewing 1: Notice the structure

Before viewing: Predict: What is the difference between information that identifies a noun and information that only adds detail?

During viewing: Write down two relative-clause examples. Mark the noun each clause describes.

After viewing: Explain to a partner why commas matter in one of the examples.

Viewing 2: Hear the logic

Rewatch a short part of the adverb-clause video.

Task: Do not transcribe. Listen for one relationship: reason, contrast, condition or time. Then retell the idea in your own words.

Follow-up question: Could the speaker have used two shorter sentences? What meaning or rhythm would change?

Reading: A school media text

Read this fictional text. The people and school project are invented.

Should our school news team use AI summaries?

Our school news team is testing a tool that can shorten long background texts. Students who prepare weekly posts say that summaries save time, especially when they first explore a topic. However, the team still checks the original sources because a smooth summary can contain missing context or incorrect details. One editor, who works mainly on sports stories, uses the summary only to find possible search terms. She then opens the original articles and compares dates, authors and evidence. Although this takes longer, she says the final post is easier to trust. The team has also agreed that students should keep their own drafts instead of replacing them with generated text. If the tool suggests a sentence, the writer must decide whether the wording is accurate, clear and suitable for the audience. The goal is not to make every sentence longer. It is to make every sentence do a useful job.

Reading tasks

Find two relative clauses. Decide whether each one identifies a noun or adds extra information.
Find three adverbial clauses and name the relationship each one shows.
Identify one short sentence. Explain why its short form works.
Summarise the text in 35–45 words without translating it.
Write one question you would ask the fictional school news team before accepting its policy.
Source check: Which claims in a real article about AI would need an external source? Name at least two.

Context vocabulary

Learn words through use, not isolated translation.

Word or phrase	Meaning in this course	Example
claim	an idea presented as true	The claim needs evidence.
evidence	information that supports a claim	The article links to evidence.
source	where information comes from	Check the source before you share.
reliable	likely to be accurate and trustworthy	One viral post is not automatically reliable.
precise	exact and specific	A relative clause can make a noun more precise.
coherent	logically connected and easy to follow	The paragraph is coherent because each sentence develops the same point.
revise	improve content and wording after a first draft	Revise the sentence for clarity.
reader load	how much information the reader must process at once	Too many nested clauses increase reader load.
emphasis	special importance or stress	A short sentence can create emphasis.
nuance	a small but meaningful difference	Although can add nuance by showing contrast.

Use again: Choose five items and use them in a 60-second spoken explanation of your revision choices.

Pronunciation and fluency

The aim is understandable English, not accent imitation.

Chunking: Read clauses in meaningful groups.

Although the source looked reliable / I checked the author / before I used the claim.

Focus:

Keep the main clause easy to hear.
Use a small pause after a long opening adverbial clause.
Do not rush through relative clauses.
Stress content words that carry the key meaning.

Private practice: You may record yourself on your own device if you want to. Recording is voluntary. Keep it private unless you actively choose to share it. No unasked uploads and no external AI analysis are needed.

Speaking

Micro-discussion: Complex or short?

Work in pairs. Student A reads the sentence. Student B chooses: keep, split or rebuild. Then switch roles.

Sentence 1: Although the app was easy to use, I deleted it because it asked for data that I did not want to share.

Sentence 2: The club posted the results. The numbers were surprising. We checked them again.

Sentence 3: The students who joined the debate prepared questions that helped them challenge claims which had not been supported.

E9-E follow-up: Do not stop after your first answer. Ask one spontaneous question: Why?, What changes if...?, Could a shorter version be stronger?, or your own question.

Mini-presentation

Prepare a 90-second explanation: One sentence I improved and why.

Include:

the original;
the revised version;
one grammar choice;
one reader-focused reason;
one possible alternative.

Your partner gives feedback on meaning first, grammar second.

Writing workshop

Step 1: First draft

Write 120–150 words for a fictional school magazine: Should students trust short online summaries?

Requirements:

clear position;
at least one source-related example;
at least one relative clause;
at least two adverbial clauses with different relationships;
sentence length that varies for a reason.

Do not add private social-media data. Use fictional names and situations.

Step 2: Sentence audit

Label each sentence:

S = short/simple enough for its purpose C = complex and useful R = needs revision

Then ask:

What relationship does this clause show?
What noun does this relative clause describe?
Is any clause only adding weight?
Where would a full stop help?
Is the key message easy to find?

Step 3: Revision ladder

Hint level 1 – Notice: Underline all clause starters such as who, which, that, because, although, if, when.

Hint level 2 – Explain: Write the function above each one: identity, extra detail, reason, contrast, condition or time.

Hint level 3 – Rebuild: Split one overloaded sentence. Join two short sentences where the relationship matters.

Hint level 4 – Reader test: Ask a partner to mark the point where they had to reread.

Step 4: Feedback that protects your own text

Use this pattern:

Meaning: I understand your main point as...

Evidence: The example supports / does not yet support the point because...

Sentence choice: This complex sentence helps because... or I would split here because...

Question: What do you want the reader to notice first?

You decide which feedback to use. Keep your original draft so you can compare versions.

Functional grammar: choose by purpose

Purpose	Useful structure	Example
identify a person or thing	defining relative clause	The source that includes the date is easier to verify.
add non-essential detail	non-defining relative clause	The podcast, which started in May, has six episodes.
explain why	adverbial clause of reason	We checked the claim because the number looked unusual.
show unexpected contrast	adverbial clause of contrast	Although the clip was popular, it gave no source.
set a condition	adverbial clause of condition	If you cannot verify the quote, do not use it as evidence.
create emphasis	short sentence	Check the source.

Error analysis

Fix the problem and explain why your version is clearer.

1. The article which was shared yesterday it contains a useful chart.

2. Although the source looked reliable. We checked the date.

3. My friend, that writes the school blog, checked the link.

4. The post was short because it was easy to read because it used simple language because the writer wanted quick attention.

5. The students checked the account, which posted the warning. Question: Is the clause defining or non-defining? Does the comma match the intended meaning?

Possible repair principles:

remove repeated subjects or unnecessary clause layers;
attach dependent clauses to a complete main clause;
choose relative words that fit the noun and clause;
use punctuation to match meaning;
split when one sentence carries too many jobs.

Mediation: for a real reader

A fictional exchange student, Sam Rivera, will join your school media group. Sam can read English well but does not know your class rules.

You receive this German note:

Vor der Veröffentlichung prüft die Gruppe Autor, Datum und Originalquelle. KI-Zusammenfassungen dürfen als Startpunkt dienen, aber Fakten müssen an der Quelle geprüft werden. Eigene Entwürfe bleiben erhalten. Persönliche Daten aus privaten Accounts werden nicht verwendet.

Task: Explain the rules to Sam in 70–90 words in English. Do not translate line by line. Select what Sam needs to act correctly.

Reader check: Use at least one complex sentence where the relationship matters, but split any sentence that becomes difficult to follow.

Research and source check

Choose one age-appropriate English article or explainer about online information, school media or digital tools.

Before using it, record:

title and publisher;
author if available;
publication or update date;
one claim you can verify elsewhere;
one perspective that may be missing;
one reason you would or would not use it in a school text.

AI rule: If a tool gives you a fact, a source or feedback, check it. Generated text can sound certain even when it is incomplete or wrong. Keep your own draft and make the final decision yourself.

Transfer challenge

You are editing three fictional messages.

A. Emergency-style notice: The sports hall is closed today because a pipe burst during the night and because the floor is wet although repairs have started.

B. School article: The repair team arrived early. It checked the floor. It reopened one entrance.

C. Debate post: Students who cycle to school say the new racks help because they are closer to the entrance, although some riders who use larger bikes say the spacing is too narrow.

For each text:

decide what the reader needs first;
keep, split or combine sentences;
explain one clause choice;
produce a revised version.

Can-do check

Rate yourself: not yet | almost | yes | confidently.

Can-do statement	My level	Evidence from my work
I can identify main and dependent clauses.
I can use relative clauses to add the right amount of noun information.
I can use adverbial clauses to show logical relationships.
I can split overloaded sentences.
I can vary sentence length for clarity and emphasis.
I can revise after feedback while keeping ownership of my text.
I can check sources and question AI-generated facts.
