Communication English II Lesson 7 Encouraging Song Section 1&2 Reading Passage Section 1 There are many songs that help people overcome sadness or troubles. Makenaide may be one of them. This song has been encouraging many people for a long time. The lyrics of Makenaide were written by Sakai Izumi, the vocalist of ZARD. It became a hit in 1993. The following year, it was adopted as the theme song for the National High School Baseball Invitational Tournament. Some schools have also been using this song for graduation ceremonies. When the Great Hanshin-Awaji Earthquake occurred in 1995, this song was often aired. Many people were able to recover their spirits by listening to it. The song also cheered people up after the Great East Japan Earthquake in 2011. Unfortunately, Sakai passed away in 2007. However, this song is still popular today. Section 2 What makes this song so attractive? The answer may be in its lyrics. The song has a message of hope for everyone. Let's take a look at the first refrain. Sakai left a piece of paper on which she wrote the lyrics. It shows that she changed a part of them. She replaced the words "Don't stop until the end" with "Keep on running until the end". She may have thought that this sounded more positive. Handout Reading No.15 Text p.94-97 She changed this part while she was actually recording the song. "Which words communicate better?" was the question she always had in her mind. She always searched for words that would encourage people. Don't give up! Just a little farther 負けないで もうすこし Keep on running until the end 最後まで走りぬけて Even though we may be apart どんなに離れてても I'll stand by you with all my heart 心はそばにいるわ Follow the dream you'll catch in the end 追いかけてはるかな夢を 1.

教科書の例では、例えば2進数の3は 0011 とかかいてるんですけど、この問題の解答は 7を 111 って書いてるんですけど、最初の0は入れるのか入れないのかどっちなんですか?🙇‍♂️🙇‍♂️ ③に「3ビットで」って書いてあるからですか、?

10 15 0 例題2 ランレングス圧縮によるデータの圧縮 図のデータ (16×16ビット) のAの部分を0.Bの部分を1として 以下の約束に従って1行ごとに圧縮すると, データ量は何ビットに なるか。また、圧縮率はどのようになるか計算しなさい。 ①最初のビット: はじまりがAの場合は 0, Bの場合は1とする。 ② 次の4ビット: AまたはBが続く個数を表す。ただし、 「個数-19 として表現する。 考え方 圧縮率は, 「圧縮後のデータ量圧縮前のデータ量」で求め られる。 解答例 1~3行は,1が16個なので, 「11111」で5ビット。 4.5行は,1が3個,0が3個.1が4個,0が3個 1が3 個なので. 「1001000100011 00100010」 で21ビット。 6~16行は, 「00101 0011 0101」 なので, 13ビット。 各行のビット数を合計すると, 5×3+21×2+13×11= 200 よって、データ量は200ビットとなる。 また, 圧縮率は, 200 16x16 ×100=78.125 となり, 約78%である。 考察 圧縮率が高いということは,よりデータ量が少なくなること であり,また圧縮率の数値はより小さくなることを意味する。 IA AJA AJAJAJAJA JAJAJA AAA BIB AIA A|A|A|A|A AIAIA A|A 1 11 1 11 14 1 11 AAAAAB 10 0 1010 し 10 11 10 10 B B [AIB BBAAA B BB BBBBAAABBB 1 C 111 010 1010 011 0 0 0 010 010 10 0 C AIA BIE B BIB BIAAAA A AJAJA BIB AIA B BIB AIAIA AIA AIA A C 00 [011 0 11 010 AIAIA AJAJA A AAA 111 0101011 0 C 010 0 010 0 10 1 3
