Choosing Between Grammatical Options in a Poster Draft
Rin is preparing a poster for a volunteer clean-up event at a Yamanashi high school. She writes three sentences:
- 'If you will join the clean-up, please bring gloves.'
- 'We will meet at the east gate because it is easier to find than the west gate.'
- 'All participants must attend the safety talk; it is compulsory.'
Her teacher comments: sentence 1 has a grammar problem; sentence 2 is grammatically fine but the 'because' clause is too conversational for a short poster; sentence 3 uses 'attend' correctly, but many students wrongly choose 'join' there. For sentence 1, the options are: (A) If you join (B) If you will join (C) If you joined (D) If you are joining. Rin wants to keep the future meaning and the polite request, and she does not want to change the sentence more than necessary.
1. Choose the best option for sentence 1 and explain why the tempting option (B) is wrong.

Best: (A) If you join.
In a first-conditional sentence about a future possibility, the if-clause uses the present simple, not 'will': 'If you join the clean-up, please bring gloves.' The main clause carries the request.
(B) 'If you will join' is tempting because the meaning is future, and learners often transfer the future idea into every clause. But English marks the future in the main clause, not in the if-clause in this structure. (C) 'If you joined' would suggest an unreal or unlikely situation, which does not fit a simple request. (D) 'If you are joining' can be acceptable in some contexts for a planned arrangement, but it is less direct and less standard for a poster than (A). The minimal correct change is therefore A.
2. Revise sentence 2 for a short poster. Keep the meaning but remove the conversational 'because' clause.

A good revision is: 'We will meet at the east gate - easier to find than the west gate.'
The original is grammatical, but a poster benefits from compressed information. The dash replaces 'because it is' and keeps the comparison. Another acceptable version is: 'Meet at the east gate (easier to find than the west gate).' This is shorter and more notice-like.
The judgement call is register: 'because it is easier to find' sounds like speech, while a poster usually prefers a phrase or parenthesis. Do not delete the comparison entirely, because it explains why the east gate was chosen and may prevent students from going to the wrong gate.
3. In sentence 3, why is 'attend' better than 'join'? Give a collocation reason, not just a translation.

'Attend' is better because it collocates with formal events such as a safety talk, a ceremony, a lecture, or a meeting. It means 'be present at' and fits a compulsory briefing. 'Join' usually means becoming a member of a group or entering an activity with others: 'join a club', 'join the clean-up'.
You can say 'join a safety talk' in casual speech, but it sounds as if you are joining the speakers or the group running it. In a poster with 'must' and 'compulsory', the register is formal, so attend the safety talk is the natural choice. The test is not whether 'join' is always wrong, but whether it fits this noun and this level of formality.
