[EX Q]: Person1: Did you hear about car accident on Spring Road yesterday ?
Person2:Yes , I did . I heard that they took both drivers to hospital . One needed surgery .
Person1: Yes . I heard he had a few broken bones too , but that the doctors have set the fractures without any problems .
Person2:The second driver was luckier . He had a concussion and needed some stitches for his head wound .
Person1: Yes . He was released from hospital yesterday evening . The other man could be there for weeks .
Person2:I understand that he ' s connected to a heart monitor and breathing apparatus . His condition can ' t be very good .
Person1: The hospital announced this morning that his condition is poor but stable . What does that mean ?
Person2:It means he ' s really badly injured , but he will almost certainly survive .

[EX Q]: Person1: Hi , Janice . Our first weekend after being employed is coming . Show me your plan .
Person2:My mom phoned me this morning , and asked me to go back home to have housework chores .
Person1: What are you assigned to do ?
Person2:God knows . Speaking of chores , I would rather do some washing than cooking .
Person1: For me , I think I will iron my shirt and trousers . Actually , weekends tend to be the most hectic day in the whole week .
Person2:I really hope that I could sleep like a log all through two nights . But ... Some one said that weekends are a bit like rainbows ; they look good from a distance but disappear before we get up close to them .
Person1: I couldn't agree more .

[EX Q]: Person1: Hi , Sara , what are you reading ?
Person2:Hi , John , I am trying to find a carpenter .
Person1: Why ?
Person2:Well , I want to build a deck in my back yard .
Person1: What for ?
Person2:So I can have a special place to hang out with friends , and also do some barbecuing on weekends .
Person1: That sounds cool . Do you mind if I recommend myself for the job ?
Person2:You ? Do you have a carpenter's license ?
Person1: Yes , of course . But I only freelance on weekends with my uncle .
Person2:Wow ! That's cool . So , let me give you some details about the deck I want .
Person1: Please go ahead , I am listening .
Person2:I'd like my deck to be at the same level as the back door .
Person1: Is your back door higher than the ground level ?
Person2:Yes , the back door is about four or five steps higher than the ground .
Person1: Okay , then you need a deck with a guardrail .
Person2:I don't like things to be fancy .
Person1: Don't worry . I will build your deck with a simple but classic look .
Person2:Hmm , that's good . Can you use cedar or redwood to build it ?
Person1: Cedar is a good choice .
Person2:Well , let's take the measurements right now .
