写真の黄色い線の部分の文構造を教えていただきたいです🙇 また、 ①ifは「ーかどうか」で訳していいのか ②thisは何を指しているか ③itは何を指しているか も教えていただきたいです。 よろしくお願いします💦

Phil Hello. This is 6 Minute English from BBC Learning English. I'm Phil. Beth And I'm Beth. Phil So, Beth, we're talking about the best education systems in the world today. You went to school here in Britain. What do you think of the British education system? Do you think it could be the best? Beth I think that it's quite good, there's probably a couple of things that I personally would change about it, but I would say it's quite good, but maybe not the best in the world. Phil Well, in this programme, we're going to be talking about the Pisa rankings. Beth The rankings are based on tests carried out by the OECD, that's an international organisation, every three years. The tests attempt to show which countries are the most effective at teaching maths, science and reading. But is that really possible to measure? Well, here is former BBC education correspondent Sean Coughlan talking to BBC World Service programme 'The Global Story'. Sean Coughlan When they were introduced first of all, that was a very contentious idea, because people said 'how can you possibly compare big countries... how can you compare America to Luxembourg or to, you know, or to parts of China, or whatever?' Phil Sean said that the tests were contentious. If something is contentious, then it is something that people might argue about it's controversial. So, at first, Pisa tests were contentious because not everyone believed it was fair to compare very different countries. Beth Phil, I've got a question for you about them. So, in 2022, Singapore was top of the reading rankings. But which of these countries came second? Was it: a) The USA? b) Ireland? or, c) The UK? Phil I think it might be b) Ireland. Beth OK. Well, we will find out if that's correct at the end of the programme. A common pattern in the Pisa rankings is that the most successful countries tend to be smaller. Talking to BBC World Service programme 'The Global Story', Sean Coughlan tells us that many large countries from Western Europe don't score that highly in the rankings. Sean Coughlan They're being outpaced and outperformed by these fast, upcoming countries - you know, Singapore, or Estonia, or Taiwan, or those sort of places which we don't historically think of as being economic rivals, but I suppose the argument for Pisa tests is, if you want to have a knowledge economy, an economy based on skills, this is how you measure it. Phil We heard that many large European countries are being outpaced by smaller nations. If someone outpaces you, they are going faster than you - at a higher pace.

問4の並び替えはどのように考えて解けばいいのですか?

3 次は、高校生のHayato (男性) が書いた文章です。 これを読んで, 間 1~ 問6に答えなさい。 *印の ついている語句には、本文のあとに〔注〕があります。(34点) I love bicycles. I've been using my bicycle since I was a junior high school student. One morning, however, I got scared on my way to school. A car passed me really fast. It almost touched my bicycle. There are only a few *bicycle lanes in my town, and I think some of those lanes are too narrow for a bicycle to use safely. I wanted to make our streets safer for cyclists, and then I read about "Copenhagen, Denmark in a bicycle "magazine. It's Aas one of the most *bicycle-friendly cities in the world. I learned more about the city on the Internet and thought it's really a wonderful city for cyclists. I'd like to write about it. In Denmark. 90% of the people have a bicycle, and in Copenhagen, 49% of the workers and students go to work or school by bicycle (27 % go by car, 18% by bus or train, and 6% on foot). Many streets in the city have bicycle lanes and bicycle traffic lights, and there is even a bicycle bridge named "The Bicycle "Snake." I was "envious of the cyclists in Copenhagen because the city is bicycle-friendly in every way. You can ride a bicycle at 20 km/h without B at red lights even when the traffic is busy, and you can bring your bicycle on trains and buses. In the 2019 ranking of "Bicycle-friendly Cities," Copenhagen was No. 1 and Tokyo was No. 16. ② A lot of people were using cars in Copenhagen, too, but around 1980, the city started making better roads and rules for bicycles, and the number of bicycle users started increasing. Around 2017, the number of bicycle users in Copenhagen became almost the same as the number of car users. I was also surprised to see that the number of bicycle accidents in Copenhagen was "lower than in other large cities. I think it's because the roads (cyclists for safe/follow/ and/ are cyclists the traffic rules. In many Japanese road safety classes, children are taught that roads are dangerous and sometimes shown shocking scenes of traffic accidents, and they learn that they must follow traffic rules when they ride a bicycle. But in Denmark. children play games in their classes. They can have fun when they learn traffic rules. Now there is a movement in Japan that gives children road safety classes in this way. Bicycles are cheaper than cars and healthier. They're also friendlier to the environment. The United Nations expects that about 70% of the people in the world will live in big cities by 2050. Such a large number of people will cause some problems, and more traffic is one of them. Copenhagen is a very good role model for Sustainable cities and communities" which is one of the U.N.'s "Sustainable Development Goals. I think Copenhagen's ideas to increase the number of bicycle users are wonderful because people there don't have to stop doing anything. They choose bicycles because the city is designed in a way that using a bicycle is more convenient than using a car, bus. or train. However, after the number of bicycle users increased, more parking spaces are needed there. (3 To make a bicycle-friendly city, just making more bicycle lanes isn't enough. We must think about the future of our cities. Denmark has made a lot of great plans and has more exciting plans for the future. For example, it's going to build a "bicycle" "superhighway" between cities and other areas by around 2045. I definitely want to ride a bicycle on it some day! 〔注〕 be cared おびえて こわがって bicycle lane 自転車専用の車線. レーン cyclist ...... 自転車乗りの人、サイクリスト pass…………〜を追いこす。 通り過ぎる narrow ・・・・・・幅が狭い Copenhagen コペンハーゲン (Denmark 「デンマーク」の首都) magazine 雑誌 on foot... 徒歩で bicycle-friendly... 自転車にやさしい traffic light...信号 (traffic は 「交通 (量)」)
