7 次の(1),(2)の英文を読んで、それぞれの問いに答えなさい。 (1) ユタカ (Yutaka) とジョージ (George)は, 2人の住むみつば市 (Mitsuba City) について調査し,英語でプレ ゼンテーション(presentation)を行いました。 ユタカがスライド(slide)を使って発表をしています。 Hello, I'm Yutaka. I live in Mitsuba City and have lived there since I was born. There are some big parks in the city, and I often played in them with my friends when I was a child. I like my city very much. people than before. Look at Slide 1. Last month, I saw news about Mitsuba City on TV. It said that our city had fewer This shows the number of people in Mitsuba City. There were more than 300,000 people in 2000. The number became larger until 2010, but after that, it started to decrease. In 2020, about 280,000 people lived there. Why did the number of people become small? To find out the reasons, I read some books and checked some websites on the Internet. I got some ideas. Look at Slide 2. This shows the number of people in Wakaba City and Aoba City. These cities are next to Mitsuba City. You can see that these two cities had more people in 2020 than in 2000. In fact, Wakaba City started some plans to help parents in 2014. For example, parents don't have to pay money when they take their sick children to the hospital. This means parents can take care of their sick children ( A ) worrying about money. In Aoba City, a new train station was built in 2008. Since then, the city has more convenience stores, clothes shops, and restaurants. Living in Aoba City became more convenient, so more people started to live there. Look at Slide 3. You can see the number of each type of shop was larger in 2020 than in 2000. Now, Aoba City has become one of the most popular cities among people. Mitsuba City is a good city, but I don't think it has many attractive points. Parents still have to pay a lot of money to take care of their sick children. Also, there are not many shops and restaurants in the city. I think Mitsuba City should have more attractive points like Wakaba City and Aoba City. I want more people to live in Mitsuba City in the future.
