When I was invited to an 次の英文を3分15秒で読んで, 1. の問いに答えなさい。 American woman's house for Christmas, her mother said to me, "We usually don't have a regular breakfast. Will you need breakfast tomorrow?" Out of reserve, I was not able to say "Yes, I will," because (1)that would require her to prepare breakfast for me 5 alone. I had no choice but to say, "No, thank you. (2)Her mother took me at my word, and assumed that I was also in the habit of skipping breakfast. When I was back at the university after the holidays, I (3)brought up the subject with a few Americans. 4)"If you had been in my place, and had needed breakfast, what would you have said?" One person said, "Your friend's mother was being frank, so I'd 00.00% 10 have said frankly, 'If you could prepare a little breakfast, I'm sure I'd enjoy it. (5) Otherwise, I'll eat out." Another person said, "That's not so polite. I'd have asked her politely, 'If you could prepare breakfast for me, I'd appreciate it." They asked me why I had been reluctant to give a frank opinion. I explained the Japanese cultural viewpoint. In Japan, immediately accepting an 15 offer of a meal is regarded as impudent; such an invitation is supposed to be declined at least once. But the host realizes that the guest has declined out of reserve, and makes it a rule to ask a second time. A Japanese guest never insists on being served a meal. The host understands the situation and the feelings of the guest and reacts appropriately. (7) "That idea has no chance at all of working here," one American said with total frankness. She continued, "Unless you're frank here, you'll go hungry all the time."

v blode 2 The following paragraph talks about school uniforms. 1) Find the topic sentence and underline it. 2) Find a sentence that disturbs the unity of the paragraph and double underline it. 3) Referring to the Study Points on page 92, discuss with your partner what is needed to make the writer's opinion more persuasive. Millal In my opinion, all high school students in Japan should be allowed to wear their own clothes to school instead of having to wear school uniforms. First, if students can choose which clothes to wear every day, they can learn to express their individuality. This year there are so many great fashions for students to choose from. Second, students can learn to take noge sli 132 responsibility for their own appearance. Third, when you wear the clothes that you like, you b joyero can relax and concentrate on your studies better. For all these reasons, allowing high school students to wear their own clothes is a good way to help them become more mature.
