S3 English: Conditionals (Zero, First and Second) (Paper 4 (error clinic))

This paper corrects ten common conditional errors one by one: will or would in the if-clause, if I was you, unless with not, would with to, mismatched tenses and misused when.

Direct answers　The if-clause carries no will or would; if I were you is fixed; unless takes no extra not; would takes the base verb with no to; the two clauses must belong to the same conditional type; when carries no hypothetical sense.

03　Answers and one-line notes

#	Answer	One-line note
1	The first one, because the if-clause cannot take will	The if-clause shows future meaning with the present simple.
2	If I were you	The second conditional uses were with every subject.
3	The present simple, because this is a zero conditional	Both clauses of a zero conditional stay in the present simple.
4	“unless” already means if not, so drop the extra not and write Unless you hurry	Unless equals if not, so adding not creates a double negative.
5	The if-clause cannot take would and should read If he came tomorrow	The if-clause takes the past simple and would appears only in the main clause.
6	Would takes the base verb directly, so it should be I would go	Would is a modal verb and never takes to.
7	The first one, since the first conditional covers real possibility	The second conditional uses the past form and so signals distance from reality.
8	If I had more money, I would buy it	A would in the main clause marks the second conditional, so the if-clause takes the past form had.
9	The first states a general truth while the second is an imagining against the facts	When marks time only and carries no hypothetical sense.
10	If you study hard, you will pass	Drop will from the if-clause and change would to will in the main clause so the pair matches.

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 →
