[EX Q]: Person1: How about the hiking ? It was freezing yesterday , are you all ok ?
Person2: Can ' t be better , it was wonderful . We had a lot of fun there . There was so much joy and walk and breathe the winter air . We arrived at the park at 9 o ' clock in the morning and didn ' t leave till 3 o ' clock in the afternoon .
Person1: You had been walking for 6 hours , isn ' t that boring ?
Person2: Of course not ! We built a snowman , some snow dogs and one big snow fort . We went sliding on the nice hill . It was a real work out . At noon , we had the most special winter picnic outside . Fortunately , we got it all on a video tape . You must come with us next time . I bet you will love it .
Person1: Well . You know I hate walking , but I can ' t wait to see your guys ' video .

[EX Q]: Person1: Sally , I ' m tired of this Western food . I really miss my mother ' s Sichuan cooking .
Person2: I ' m sure you do miss that type of cooking . But can ' t you try to get used to Western food ?
Person1: I have tried . But Americans like butter , bread , sugar , and cream too much .
Person2: I suppose you ' re right , Lee . Maybe that ' s why so many Westerners are overweight .
Person1: It ' s interesting that Americans work very hard at their jobs , do not take naps during the day , and yet they can be so heavy .
Person2: You see , because we are often busy working , we eat too much fast food , and that food is very fattening .
