1文目の訳が「実際私は彫像や写真を好むのに間違った理由はないと思う。」 にならない理由を教えてください。

12 演習12 (問題→本冊: p.25) (es.q: +-)ATAN Actually I do not think that there are any wrong reasons for liking a statue or a picture. Someone may like a landscape painting because it reminds him of home, or a portrait because it reminds him of a friend. There is nothing wrong with that. All of us, when we see a painting, are bound to be reminded of a hundred- and-one things which influence our likes and dislikes.> 【文全 【全文訳】 実際私は彫像も絵も好きになってはいけない理由などないと思う。 わが家を 思い出すという理由で風景画を,あるいは友人を思い出すというので肖像画を好む 人がいるかもしれない。 それはどこも間違っていない。 私たちは皆, 絵を目にする と必ず, 私たちの好き嫌いに影響している非常に多くのものを思い出す。 【解説】 下線部の which の後は, influence (Vt) likes and dislikes (O) だから, which は関係代名詞主格。第1文は not を anyとくっつけるとわかりやすい。 第2文の構 造は以下のとおり。 (re.g a landscape painting because ~ 523 philome like Vt wasabatangiesb saori sus 29orurls brus beans ausy arth nt otom brun som ed lilw start yab ono equho yaward to to sombng Somed Art n and grblame off aben a portrait because ~ 文金】

If you did do all had (2) that ability, maybe you would spend more time practicing soccer, learn the instrument that you always wanted to play, study harder for that big test, or try to save more money for the future. 2 What would you do if you had the ability to turn back the clock? This was a question (あ) which Mr. Woodall, a high school teacher in Philadelphia, asked his students. Mr. Woodall wanted to know what was important to his students but was pleasantly surprised to see the results. I think their answers will be very interesting to you, too. 3 Mr. Woodall expected to see answers (1) which were connected to the own good of the students, but (3) he was wrong. The majority of the which he received from his students were for the good of answers (5) others. 4 A very common answer he found was," If I could turn back the clock, I would take back some things that I said to a friend." Apparently, many of the students regretted saying something (5) ( ) hurt their friends and wanted to change that. Surprisingly, close to 40% of the students answered this way. Another common answer was about pets. “(6) If I were able to turn back the clock, I would spend more time with my dog,” or “(7) I would be nicer to my cat,” were some common answers. Almost 25% of the students missed their pet very much and wanted to show more love. These pets included dogs, cats, birds, rabbits and other animals. 6 There were other answers about reading more books, studying harder, or eating less junk food. However, Mr. Woodall was quite impressed with his students and their concern for others. He decided to share all of the answers with his students, and the students enjoyed hearing the different answers. Mr. Woodall decided to try this activity with his students every year. By asking, he felt he would learn a lot about his students. turn back (時計を) 巻き戻す pleasantly 心地よく expected to 〜するだろうと思う good 利益 majority 大多数。 大部分 take back 取り消す apparently どうやら~らしい close to ~近く be nice to 〜にやさしい junk food ジャンクフード concern for 〜への気遣い。 配慮 )に適切な語を入れなさい。 問1 ), (5) ( (1) (were ) (5) ( that ) 問2 下線部(2) は具体的にどのような能力ですか。 日本語で答えなさい。 ( 問3 「下線部(あ)~(う)の which のうち, 他と用法の異なるものを1つ選び, 記号で答えなさ い。 ( う ) 問4 下線部(3) の内容を具体的に説明した次の文の( )に適切な日本語を入れなさい。 回答は( 大部分は ( に結びつくものと予想していたが, だった。 問5 下線部(4), (6) を日本語に訳しなさい。 (4) (6)

Phil Hello. This is 6 Minute English from BBC Learning English. I'm Phil. Beth And I'm Beth. Are you a big reader, Phil? Phil Sure, I enjoy reading - and it's also a great way to pass the time on my daily commute to work. But reading isn't just a nice thing to do - it's an essential skill, something you need for everyday activities, whether that's finding out the news by reading a newspaper or buying groceries by reading the labels. Beth And that's why I was shocked by a recent UN report estimating that around the world over 700 million adults are illiterate, which means they can't read or write. Phil Wow! That's a huge number of people excluded from doing basic day-to-day things. So, what can be done to get more adults reading and writing? In this programme, we'll be hearing about projects in two very different countries trying to do just that. And, as usual, we'll be learning some useful new vocabulary as well. Beth But first I have a question for you, Phil. I mentioned a recent UN report on the high numbers of people unable to read and write, but illiteracy is not a new problem. Since 1967, the UN has been highlighting the importance of literacy, being able to read and write, with a day of celebration called International Literacy Day. But when does it take place? Is it: a) the 8th of March? b) the 8th of June? or, c) the 8th of September? Phil I think International Literacy Day is on the 8th of September. Beth OK, Phil, we'll find out if that's correct at the end of the programme. The biggest reason people grow up illiterate is not going to school, and that's especially true for people living in the coastal towns of Bangladesh. Because these towns flood regularly, families are always on the move, making it hard for children to get an education. Phil The Friendship Project teaches reading and writing to groups of Bangladeshi women and girls. They also teach numeracy which means the ability to do basic maths like counting and adding up. Here one student, Rashida, explains the impact it's had on her to BBC World Service programme, People Fixing The World: Rashida My parents never sent me to school and I've suffered from not being able to read and write. My children were embarrassed that I was illiterate. I couldn't even do basic accounting. Until now, I've had to use my fingerprint as a signature as I was illiterate, but now I can sign my name because I can read and write thealphabet, and I'll also be able to keep an account of my expenses. No one can cheat me anymore. Beth Before the Friendship Project, Rashida couldn't write her signature – her name written in her own handwriting. Instead, she had to use her fingerprint. Now, Rashida has learned the alphabet and also some basic maths, so she knows how much money she's spent, and how much she has left. This means no-one can cheat her, can trick or swindle her into taking her money.
