S3 English: Conditionals (Zero, First and Second) (Paper 2 (intermediate))

This paper practises the first conditional: present simple with will, unless against if not, negative if-clauses, can and may in the main clause, and the rule that time clauses also avoid will.

Direct answers　The first conditional covers a real future possibility; the if-clause is present simple and the main clause is will plus the base verb; unless means if not and takes no extra not; the main clause may use can or may; when and as soon as clauses also avoid will.

03　Answers and one-line notes

#	Answer	One-line note
1	rains / will cancel	The first conditional uses the present simple in the if-clause and will plus the base verb in the main clause.
2	If plus present simple, then will plus the base verb	The if-clause states a future condition but the verb stays in the present simple.
3	will pass	The main clause uses will plus the base verb to show the future result.
4	If you do not hurry, you will miss the bus	“Unless” means “if not”, so it already carries the negative and takes no extra “not”.
5	does not come	A negative if-clause uses do or does plus not plus the base verb.
6	If you do not stay here, you will get lost	A command followed by otherwise or or becomes a negative if-clause.
7	will let	The if-clause takes the present simple “calls” and the main clause takes will plus the base verb.
8	can and may, and might also works	Swapping in can or may shows ability or permission, and the pattern stays modal plus base verb.
9	Time clauses behave like if-clauses and use the present simple for future meaning	Clauses after when, before, after and as soon as never take will.
10	Drop will from the if-clause and write If it rains, we will stay at home	The if-clause takes the present simple and only the main clause carries will.

04　What to do after marking

After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
Repeat the same item two days later; move to the next paper only when both attempts are correct.
Parents only need the answer and note columns; there is no need to explain every item.

Ask one question first: is the sentence a general truth, a real future possibility, or an unreal imagination. General truth takes present plus present, a real possibility takes present plus will, and imagination takes past plus would. The if-clause never takes will or would.Tutor Registration →
