Free cheat sheet 01 · B1 and above
Find the main idea before adding the details.
When a sentence gets tangled, return to its centre: who or what, and what happens. Add the useful detail after that.

What to use—and when
Give your listener a clear subject.
Say what happens, or what the subject is like.
Some verbs need an object or description. Then add where, when or why if it helps.
Understand the choice
A short complete sentence gives you somewhere reliable to start. Not every verb needs an object.
Some verbs give a complete message on their own.
An object receives the action. Ask what or who after the verb.
Be, seem, become and feel can link the subject to a description, rather than an object.
Understand the choice
Build one idea, then expand it. This gives your listener a clear route.
| Layer | Sentence | What changed? |
|---|---|---|
| Core | I booked a lesson. | Who + action + what. |
| Time | I booked a lesson yesterday. | When it happened. |
| Reason | I booked a lesson yesterday because I want to speak more confidently. | Why it happened. |
| Relevant detail | I booked a speaking lesson yesterday because I want to feel more confident at work. | A clearer purpose. |
Understand the choice
Check these before adding a more complicated connector.
Use is / has / does and a present-simple -s with he, she and it.
English usually needs a stated subject, even when the idea feels obvious.
A chunk gives you a useful sentence opening, but you still need to finish the meaning.
Understand the choice
A clause contains a subject and a verb. Some clauses can stand alone; others depend on a main idea.
| Pattern | Example | Remember |
|---|---|---|
| Main idea + because + reason | I left early because I was tired. | Because introduces the reason. |
| Although + contrast, main idea | Although I was tired, I stayed. | The although clause needs the main idea. |
| Main idea. However, new idea. | I was tired. However, I wanted to stay. | However does not join two full sentences with just a comma. |
The quick check
Notice the difference
Short, but complete.
The same clear centre, with time and reason added.
Common slips
Instead ofMy brother in London.
UseMy brother lives in London.
The first version has no verb.Instead ofBecause I was tired.
UseI went home because I was tired.
In a standalone written sentence, the reason needs a main clause. As an answer to a spoken Why question, the shorter version can be natural.
