Lesson 10 drill — Reason connectors: because / since / as / due to + the reason is…
Three reason linkers join two clauses: BECAUSE (most common, most neutral), SINCE (the reason is known/obvious), AS (often at the start, slightly formal). BECAUSE OF / DUE TO are followed by a NOUN, not a clause. To make a reason really stand out, use 'The (main) reason is that…' or 'That's why…'.
Choose: 'We stayed in ____ it was raining.'
Choose: 'The match was cancelled ____ heavy rain.'
'Since' here means…
Most formal:
Which is WRONG?
I'm tired ____ I didn't sleep well.
The flight was delayed ____ heavy snow.
____ we're already late, let's take a taxi.
The ____ reason is that the office is too noisy.
I love mornings — ____ why I get up so early.
