Relatives: non-defining and connective: PEG 78-84 Combine the following pairs or groups of sentences, using relative pronouns. 1 Tom had been driving all day. He was tired and wanted to stop. 2 Ann had been sleeping in the back of the car. She felt quite fresh and wanted to go on. 3 Paul wanted to take the mountain road. His tyres were nearly new. 4 Jack's tyres were very old. He wanted to stick to the tarred road. 5 Mary didn't know anything about mountains. She thought it would be quite safe to climb alone. 6 He gave orders to the manager. The manager passed them on to the foreman. 7 She said that the men were thieves. This turned out to be true. 8 The matter was reported to the Chief of Police. He ordered us all to be arrested. 9 In prison they fed us on dry bread. Most of it was mouldy. 10 We slept in the same room as a handcuffed prisoner. His handcuffs rattled every time he moved. 11 We lit a fire. It soon dried out our clothes. 12 They rowed across the Atlantic. This had never been done before. 13 The lorry crashed into a bus-load of schoolchildren. Six of them were slightly injured. 14 She refuses to use machines. This makes her work more arduous. 15 I met Mary. She asked me to give you this. 16 The women prayed aloud all night. This kept us awake. 17 The river bed is uneven and you may be in shallow water one moment and in deep water the next. This makes it unsafe for non-swimmers. 18 Mary said that there should be a notice up warning people. Mary's children couldn't swim. 19 Ann said that there were far too many notices. Ann's children could swim very well. 20 He paid me £5 for cleaning ten windows. Most of them hadn't been cleaned for at least a year. 21 Jack, the goalkeeper, and Tom, one of the backs, were injured in last Saturday's match. Jack's injuries were very slight. He is being allowed to play in today's match. This is a good thing because the team hasn't got another goalkeeper. (Combine the last three sentences only.) 22 But Tom's leg is still in bandages. He will have to watch the match from the stand. 23 Mr White didn't get a seat on his train this morning. This put him in a bad temper, and caused him to be very rude to his junior partner. The junior partner in turn was rude to the chief clerk; and so on all the way down to the office boy. 24 On Monday Tom's boss suddenly asked for a report on the previous week's figures. Tom had a hangover. He felt too sick to work fast. (Combine the last two sentences only.) 25 His boss didn't drink. He saw what was the matter and wasn't sympathetic. 26 In the afternoon he rang Tom and asked why the report still hadn't arrived. The report should have been on his desk by 2 o'clock. 27 Tom's headache was now much worse. He just put the receiver down without answering. This was just as well, as if he'd said anything he would have been very rude. 28 Fortunately Ann, the typist, came to Tom's assistance. Ann rather liked Tom. 29 Even so the report took three hours. It should have taken an hour and a half. 30 I went to Munich. I had always wanted to visit Munich.
