B You enjoy outdoor sports and have found an interesting story in a mountain climbing magazine. Attempting the Three Peaks Challenge By John Highland Last September, a team of 12 of us, 10 climbers and two minibus drivers, participated in the Three Peaks Challenge, which is well known for its difficulty among climbers in Britain. The goal is to climb the highest mountain in Scotland (Ben Nevis), in England (Scafell Pike), and in Wales (Snowdon) within 24 hours, including approximately 10 hours of driving between the mountains. To prepare for this, we trained on and off for several months and planned the route carefully. Our challenge would start at the foot of Ben Nevis and finish at the foot of Snowdon. Ben Nevis (▲1344 m) Scafell Pike (▲977 m) Snowdon (▲1085 m) We began our first climb at six o'clock on a beautiful autumn morning. Thanks to our training, we reached the summit in under three hours. On the way down, however, I realised I had dropped my phone. Fortunately, I found it with the help of the team, but we lost 15 minutes. We reached our next destination, Scafell Pike, early that evening. After six hours of rest in the minibus, we started our second climb full of energy. As it got darker, though, we had to slow down. It took four-and-a-half hours to complete Scafell Pike. Again, it took longer than planned, and time was running out. However, because the traffic was light, we were right on schedule when we started our final climb. Now we felt more confident we could complete the challenge within the time limit. Unfortunately, soon after we started the final climb, it began to rain heavily and we had to slow down again. It was slippery and very difficult to see ahead. At 4.30 am, we realised that we could no longer finish in 24 hours. - 16- (2110-16)

中3英語です。 宿題の答え合わせをしたいのですが、、解いてくださる方いたらお願いします🙇🏻‍♀️🙇🏻‍♀️

5 次の英文を読んで、あとの問いに答えなさい。 <城西大川越改〉 All countries use money, In the US, they use dollars, In Japan, they use yen, In India, they use rupees. If you want to go to a different country, you must change your money. When you go from England to India, you ( ① ) have to change pounds into rupees. When you go from Japan to the US, you must change yen into dollars. A country's money is called its Currency. Changing one country's money into A country's money is called "currency exchange." Currency exchange is not free, You ( ③ ) go to a bank or special money changing office. They will make you pay some small amount in order to change your money, So, it costs ( ④ ) to change money. Exchanging money can be confusing. When you arrive in a new place, you do not know the prices in the new currency right away So, you do not always know how much money you are spending. For example, let's imagine one dollar is exchanged for 120 yen. So, an American in Japan may have little idea how much his or her lunch really costs in dollars! 5 Currency exchange problems used to be very bad in Europe. Europe has many very small countries, and people travel from country to country a lot in Europe. For this reason, they decided to change to one currency, the Euro. Today, most of the countries in Europe use the Euro as their money. In fact, more and more countries will use the Euro in the future. Now you (⑦) travel from Italy to France, or from Spain to Finland, and never have to change your money. The idea of having one currency seems popular. Maybe one day B parts of the world could join their currencies, like countries in the Middle East, or countries in Asia. Maybe one day we will have C currency for the whole world! (1) ①, ③, ⑦ の ( [ must can will don't cannot] に適する語を,次の [ ]内から1つずつ選び、 書きなさい。 3 (2) 下線部②の意味として適するものを,ア~エから1つ選びなさい。 ア 為替 イ口座 ウ 通貨 エ 利息 (3) ④( に適する1語を本文中から抜き出して書きなさい。 (4) 下線部⑤の理由を日本語で説明しなさい。 (5) A Cに入る語の組み合わせとして最も適するものを, ア~エから1つ選びなさい。 B A ア(another / one / another ) one / another / the other ) イ ( ウ(another / other 1 one ) エ(the other / other / another ) (6) 下線部⑥の内容として適するものを, ア~エから1つ選びなさい。 ア 人々が新しい国を訪れたとき, すぐに両替をすることができないということ イ ヨーロッパには小さな国がたくさんあり, 両替をする銀行の数が不足しているということ ウヨーロッパには小さな国がたくさんあり, 人々は国から国への移動を何度もするということ エ イタリア, フランス, スペインなどを旅するとき, 人々は多くのお金を持ち歩かなければいけないとい うこと 13
