We can go out to dinner before that (9)Text 8M: What’s in the picture, Stella? I thought this was going to be a Mother’s Day card.W: This is a green queen in a field of flowers. (10)M: Oh, I see. And what are these orange things all around her? Are those the flowers?W: No, you have to imagine the flowers, Dad. Those are the members of her family. That’s you, and you’re standing next to Uncle Dan. This is me, and Donald is next to me because he’s not in school yet. (11)M: And who is this between us? I guess that’s Harold with a mouse in his mouth.W: Yes. He’s giving the queen a gift because he’s a royal cat, you know.M: I see. And what does this have to do with Mother’s Day?W: I want my mother to feel like a queen, so I put her in the center of the picture. (10)M: That’s lovely, dear. I’m sure she’ll love it. Perhaps we should just write “Happy Mother’s Day” on it so she knows what it’s all about. (12)W: OK. Can you hand me the purple crayon? (12)Text 9W: Steven, how are you feeling today?M: Awful. (cough)W: Would you like something to eat?M: No, thank you, Mrs. Smith. I don’t think I feel well enough to eat anything. I’m cold and my whole body aches. (13)W: Hmm. That sounds like the flu to me. (13)M: Oh, no. Should I go to the doctor?W: I don’t think you’ll have to. If you stay home and rest, you should be OK in a day or so. (14)M: But back in Korea, I always went to the doctor when I wasn’t feeling well.W: Oh, all right. I can make an appointment for you to see our family doctor. I suppose you’ve got medical insurance.M: Oh, yes. All overseas students in the U.S. are required to have a group medical plan.W: That’s good. According to this on my phone, the first opening at the doctor’s office is on Wednesday.(15)M: Two days from now? (15)That’s a long time. Am I supposed to just suffer here for two days?W: Don’t worry. I’ll get you some medicine from the local dru gstore. (16)You’ll feel better by tomorrow, I’m sure.M: I hope so. I have a test on Tuesday, and I don’t want to miss it.Text 10You are standing in front of the tallest man-made structure in the world, the Burj Khalifa. It reaches a height of 828 meters. (17)Construction began in 2004, and was finally finished in 2009.One year later, it was officially opened,(18) and remains the most famous building in the main business district. It was designed by a man named Adrian Smith, (19) who also acted as the architect for other famous buildings around the world in countries like Saudi Arabia, the United States, and China. The Burj Khalifa’s chief engineer was Bill Baker, and with the help of thousands of workers from South Asia, they achieved the impossible. It is truly a wonder of engineering. There are a total of 162 floors in the tower. The Armani Hotel occupies fifteen of its floors and has 304 rooms. There are restaurants, swimming pools, company offices, observation decks, and even a mall. The only thing more amazing than staring up at this structure is experiencing it from the inside. Follow me. (20)。
