5 UNIT3 Reading Passage 10 15 20 20 25 30 Listening When important events are happening around the world, most people turn to traditional media sources, such as CNN and BBC,¹ for their news. However, during the invasion of Iraq by the United States and its allies in early 2003, a significant number of people followed the war from the point of view of an anonymous² Iraqi citizen who called himself "Salam Pax" (salam means "peace" in Arabic, and pax means "peace" in Latin). Salam Pax wrote a diary about everyday life in Baghdad during the war, and posted it on his web site. Pax's online diary was a kind of web site known as a "blog." Blogs, short for "web-logs," are online diaries usually kept by individuals, but sometimes they are written by companies and other groups of people. They are a rapidly growing type of web site on the Internet. There are estimated to be several hundred thousand blogs on the Internet, and with the popularity of other social media sites, the number of people writing online about their lives continues to grow. may find A blog differs from a traditional web site in several ways. Most importantly, it is updated much more regularly. Many blogs are updated every day, and some are updated several times a day. Also, most blogs use special software or web sites which are specifically aimed at bloggers, so you do not need to be a computer expert to create your own blog. This means that ordinary people who computers difficult to use can easily set up and start writing their own blog. In 2003, the Internet company AOL³ introduced their own blogging service, enabling its 35 million members to quickly and easily start blogging. There are many different kinds of blogs. The most popular type is an online diary of links, where the blog writer surfs the Internet and then posts links to sites or news articles that they find interesting, with a few comments about each one. Other types are personal diaries, where the writer talks about their life and feelings. Sometimes these blogs can be very personal. There is another kind of blogging, called "moblogging," short for "mobile blogging." Mobloggers use cell phones to take photo's, which are posted instantly to the Internet. When the content and images posted online involve news subjects, mobloggers become citizen journalists. In fact, the Korean web site OhMyNews was a well known source for articles from international citizen journalists. However, in 2010, OhMyNews stopped posting new articles. Instead, it is now a blog site where citizen journalists can choose what makes the headlines, or just share ideas about how regular people are changing the news world. Anyone who visits the web site of a big media company can clearly see how the idea of blogging has changed the reporting of news. Quite often, a list of reader comments follow news articles. It seems that the news is becoming less like a report or a lecture, and more like a conversation, where anyone can join in.

UNIT 1 5 Reading Passage 10 15 20 20 25 Listening There are more than 37,000 known species of spiders in the world in a wide variety of shape's and sizes! The largest spiders in the world live in the rain forests of South America and are known by the people who live there as the "bird-eating spiders." These spiders can grow up to 28 centimeters in length- about the size of a dinner plate, and, as their name suggests, have been known to eat small birds. In comparison, the smallest species of spider in the world is native to Western Samoa. These tiny spiders are less than half a millimeter long — about the size of a period on this page and live in plants that grow on mountain rocks. - Some people like to keep spiders as pets, particularly tarantulas, which are native to North America and can live for up to twenty-five years, Most people, on the other hand, do not like touching spiders, and a significant number of people are afraid of them, mainly because of their poison. However, despite their bad reputation, only thirty of the 37,000 known species of spiders are deadly to humans. Spiders actually provide benefits to humans, by catching and eating harmful insects such as flies and mosquitoes. - - The main thing that makes spiders different from other animals is that they spin web's to catch the small insects they feed on. The unique silk of a spider's web is produced by special organs found spider web is five times in the lower part of the spider's body. It is light, elastic, and strong stronger than steel. Additionally, it is completely biodegradable. This means that the web will making it perfect for uses completely decompose¹ and eventually return to nature over time such as making fishing nets. Some people have tried to raise spiders commercially in order to collect the silk these spiders produce, but no one has ever really managed to make a go of it. One reason why these businesses never stand a chance is because it takes 670,000 spiders to produce half a kilogram of silk, and all of these spiders need living insects for their food. In addition, spiders are usually solitary² animals, and need to be kept alone. Researchers at an American company working together with two U.S. universities may have found a solution to making artificial spider web. Using genetically modified silkworms,³ the company hopes that in the long run it will be able to make large quantities of very light, very strong fiber for medical as well as other uses. Additionally, because the manufacture of the artificial web is from living silkworms, the industry potentially would be non-polluting and less harmful to the environment

①、②、④は分かったのですが③、5が解説を見たのですがよく分かりません。誰か分かりやすく教えてくださいお願いします🙇‍♀️

ADL 内の先生と生徒の会話文を読んで、下の内の生徒が完成させた【証明】の から⑤に当てはまる数や式をそれぞれ答えなさい。 しからし 「姓 「一の位が0でない 900未満の3けたの自然数をMとし,Mに99をたしてできる自然 数をNとすると、Mの各位の数の和とNの各位の数の和は同じ値になるという性質が あります。例として583で確かめてみましょう。」 生徒「583の各位の数の和は5+8+3=16です。 583に99をたすと682となるので,各位の DAG 数の和は 6 +8 +2=16で同じ値になりました。」 先生「そうですね。 それでは、Mの百の位、十の位, 一の位の数をそれぞれ a,b, そして、この性質を証明してみましょう。 a,b,cのとりうる値の範囲に気をつ MとNをそれぞれa,b,c を用いて表すとどうなりますか。」 生徒「Mは表せそうですが,NはM+99 で…・・ 各位の数がうまく表せません。」 先生「99を100-1におきかえて考えてみましょう。」 生徒が完成させた 【証明】 3けたの自然数Mの百の位、十の位一の位の数をそれぞれα, b,c とすると 1以上8以下の整数,bは0以上9以下の整数,cは1以上9以下の整数となる。 このとき *MOHOTO00S10 M= ① xa+ また,N=M+99 よ N=| 1 xa+ ② x 6 + c と表せる。 HOTO VOUS (2) | xb+c + 100-1 となるから N= ①² x ③ +② v x ④ + ⑤ Nの百の位の数は 十の位の数は4円 一の位の数は ⑤ となる よって、Mの各位の数の和とNの各位の数の和はそれぞれ a+b+c となり、同じ値 pal ob 26 TERMASU HALL SMA
