视听说教程3最后一题原文加答案

Sun-hee, Tara, and Claudia were preparing to go to Mexico for a vacation.While Sun-hee was talking to Mike on the phone, Claudia and Tara had some trouble preparing for the trip. First, Tara couldn’t find her bag and then Claudia didn’t know where her ticket was. Things got worse when Claudia couldn’t find her money and cell phone. But Sun-hee helped them out. She seemed to be totally relaxed because she had already finished getting ready. Sun-hee told Mike about all the errands she had done earlier that day. She had confirmed her flight, got traveler’s checks, changed her voice-mail message, and paid the bills. Finally, Tara and Claudia were ready to go and Sun-hee checked to be sure they had everything. However, after they left, Sun-hee soon came running back in. Why? She had forgotten to take her ticket and passport! Unit two It was a very hot day and Takeshi came home to find Mike using his imagination to stay cool. Takeshi complained about not going to Hawaii with other friends and about not having an air conditioner in the room. Mike tried to teach Takeshi how to imagine being at the beach. When Takeshi asked where the water for the beach was, Mike sprayed Takeshi with water which made Takeshi angry. Then, Mike pretended to use an ironing board for surfing even though Takeshi told him not to. So, Takeshi decided to use his imagination and he threw water all over Mike, pretending it was a wave. Mike wasn’t too happy, but Takeshi thought it was pretty funny! Unit three Claudia and Roberto were talk ing about Roberto’s new job. Roberto was excited, but he was a bit nervous about learning a new software program. Claudia told him not to worry and promised to help him learn it. Then Roberto asked Claudia if she might get promoted soon because her boss had been transferred to a different office. Claudia said that getting promoted was not a big deal. She explained that her goal was to quit her job someday and relax. Roberto, however, said his life was planned already, almost right up to retirement. He thought it was important to have well-defined goals, but Claudia said that Roberto should keep his options open, and ―go with the flow.‖Roberto agreed, but only if the ―flow‖ followed his plan! Unit four Sun-hee didn’t feel well, so Tara asked Takeshi and Mike to come over. When they arrived, Takeshi asked Sun-hee how she was feeling. Sun-hee said she was very tired, a little dizzy, and that she might even have a fever. Tara then explained that Sun-hee had also been very anxious about a meeting with the president of her university. Mike told Sun-hee to eat something, but she refused and said, ―I can’t eat. I’m not hungry.Then the phone rang. It was the president’s secretary. She informed Tara to tell Sun-hee that the meeting had been canceled. When Sun-hee got the news, she immediately started to feel better and said, ―It must be a miracle or something.‖ But her friends knew it was not a miracle. She had just been nervous about the meeting!
