第2問対策 意見文の読み取り ③ No. Name Class Tomom 目標解答時間: 7分 共通テストドリル リーディング 改訂第5版 Your English teacher gave you an article to help you prepare for the debate in the next class. A part of this article with one of the comments is shown below. Net Shopping: Convenient but Addictive By Tony Sutton, Philadelphia 12 June 2019 9:20PM Internet shopping is very convenient. At night or when it is raining or snowing. 1.66 billion people (in the world) are estimated to have used the Internet for shopping in 2017.) In the same year, you can buy things comfortably from your room. total sales of online retail amounted to 2.3 trillion US dollars. It is predicted that the amount will reach 4.48 trillion US dollars(in 2021.) Some people object to this situation which could be described as a retail revolution. A male says, "I was one of those who became addicted to the convenience of online shopping and was purchasing almost everything online. But now, when I need something, I first think of going to a store to look for it." A female says, "The goods which are delivered are sometimes different from what I had in my mind. As it is troublesome to send them back, I end up using something that I do not really like. If I buy things at stores, such a situation does not happen so often. I will not buy unnecessary things, so I will not regret shopping. Therefore, recently I seldom shop online, and instead buy things at stores after seeing them directly." 9 Comments Newest Jennifer Frazer 20 June 2019 9:32AM /10 I also bought too many things online before, but now I have come to order only necessary things. The point is how to control yourself. As there are few shops in my neighborhood and there are plenty of goods on the Internet, I will continue to use the Internet for shopping.

You are the editor of a school English paper. Stephanie, an exchange student from the US, has written an article for the paper. More Moon Decor Loun Where do you live? When people think of the places with the "best quality of life," they often imagine NY, London or Hong Kong, with exciting nightlife, parks, and tourist sites. However, many studies have concluded that (big cities do not offer the highest quality of life. Let's take a look at the results of the studies. In a recent survey of 56 cities on quality of life, only one big city, Tokyo, was in the top half of the ranking. Edinburgh (UK) came in fourth. It is almost even with Copenhagen (Denmark), but is far behind Zurich (Switzerland) Zurich beat Wellington (New Zealand), which came in second. These four winners are all mid-sized cities. Research shows that people were increasingly moving to mid-sized cities because: ▸▸ Housing costs can be up to 50% cheaper Property taxes can be up to 25% lower Fuel costs can be up to 4% cheaper Cultural attractions in these cities are also comparable to those of big cities. Mid-sized cities have culture that is just as attractive as that of large cities. Of course, people say mid-sized cities have some problems, for example, public transportation is usually less developed and jobs are somewhat fewer than big cities. 問1 /10 ング 改訂第5版 In terms of quality of life, which shows the cities' ranking from highest to lowest? 1 0 Copenhagen - Edinburgh - Wellington-Zurich [② ③ Copenhagen-Wellington-Zurich - Edinburgh Zurich Copenhagen - Edinburgh - Wellington Zurich-Wellington - Copenhagen - Edinburgh RUOTA P ①②③④ (2点) 2 According to Stephanie's report, one advantage of a mid-sized city is ①cultural activities are equal to those in big cities 2 guides are friendlier than in small towns property taxes are about the same as other locations public transportation is cleaner than in big cities ① ② ③ ④ (2点) how 問3 The statement that reflects one finding from the research is 3 ①Both rural areas and big cities have plenty of excitement.' 3 Keep your options open when choosing a place to live in.' People are moving to big cities nowadays to earn more.' 4 The best cities to live in may not be the biggest. ① ② ③ ④ (2点) Which best summarizes Stephanie's opinions about the towns and cities of Japan? 問4 4 I believe this same trend might be true (in Japan) as well. In some local guidebooks, Nagoya and Sendai - two mid-sized cities were among the top five places (in Japan) for quality of life. Housing and other living costs (in both these cities) are also cheaper than those of big cities. ①A more international lifestyle is available in Tokyo of Osaka. Big and mid-sized cities are similar in most ways in terms of job opportunities. 3 City governments try to provide easy access to public transportation. Mid-sized cities are getting more popular than big cities. (★およそ270 words) ① ② ③ ④ (2点)
