Use conditionals to support an opinion

A second conditional turns a general claim into a concrete result. Claim, then "If…, … would…" as the reason is a strong pattern for the Academic Discussion.

Academic Discussion

Should universities make attendance optional?

Answer

I think attendance should stay required. If lectures were optional, many first-year students would fall behind before they realized it.

The opinion comes first, and the conditional gives a specific consequence, which reads as reasoning rather than a bare claim.

Other words that work like "if"

  • Unless = if not: "You cannot enter unless you have a ticket."
  • As long as / provided that = only if: "You can borrow it as long as you return it Friday."
  • In case = as a precaution: "Bring an umbrella in case it rains."

Common mistakes

  • If it will rain, we will stay home.
    If it rains, we will stay home.
  • If I would have money, I would travel.
    If I had money, I would travel.
  • If I had known, I would told you.
    If I had known, I would have told you.
