LEARN THIS! Participle and infinitive clauses

We lived in a large house, built (= which had been built) in the 17 century.

d. Infinitive clauses begin with an infinitive which replaces an active or passive verb.

PART 1

Apollo 13, launched from Florida on 1 April 1970, was the third Apollo mission to land on the moon. The three astronauts chosen for the mission were James Lovell, Fred Haise and John Swigert. The launch, watched by millions on TV, went smoothly and for the first two days in space, everything went well. The crew gave a 49-minute TV interview explaining how they lived and worked in zero gravity. However, nine minutes after the interview finished, a tank containing oxygen exploded and John Swigert, noticing a red warning light, said the famous words: ‘Houston, we've had a problem here- They checked all their equipment and realised that they were running out of water, power and oxygen — hard and fast. They were in a damaged spaceship floating 320,000 kilometres from Earth.
