Do companies need to improve the noy they treat their workers? and I think that companies need to improve the way they treat their workers and I have two reasons to support my opinion. The first reason is that companies should give same oppotunities to female. Some companies discriminate between male and female. For example, they decrease the number of recruies of female, and employees divided works such as cleaning and dest work between man women so they have to aim the mole female equality. The second reason is that work-life balance is serious issue by employees because they spend too much time to work. Companies should make holiday and decrease overtime work. If they do that, workers will balance work and life 110 for the two reasons mentioned above that companies need to improve the way they treat their workers. 90

20 Unit 1 - History - Gutenberg is famous for inventing printing, but he didn't really invent it. He invented a better way of printing. [2] For hundreds of years people used blocks of wood* to print. They used a knife to cut words backward in the block of wood. Then they covered the block with ink and pressed it onto paper. When they pulled the paper from the inky blocks, the words appeared on the 金属 5 paper in the right direction. In Korea and China, people printed with metal type* instead of 右向き wood. (2)Either way, printing was difficult and very slow. It took several years to make one copy of a book. [3] Books were very expensive and rare. Only ( 3a ) people could buy them, and ( 3b ) 10 people could not read. But, as ( 3c -) people learned to read, books became more popular. So people wanted to find a quicker, better and less expensive way to print books. One of these people was Johannes Gutenberg. opsugas.l Y tinU 9003 iinil 4 Gutenberg was born in Mainz, Germany, around 1400. He was good at working with metal, but probably had no idea how people printed in China. His idea was to make a piece Clarey operan 15 of metal type for each letter of the alphabet and use the letters (4)over and over. (5)He could put the type together to make words and arrange words to make pages. With ink on the type, he could press paper on them to print a page. A "printing press" machine could make hundreds of copies of a single page quickly. After that page, he could rearrange the same letters to make other words and print other pages. LISSH Si nou 5 It took Gutenberg a long time to make the type for each letter of the alphabet. When he finished the type, he didn't have enough money to make the printing press. He borrowed money from a man named Johann Fust. After many years, Gutenberg's printing press was Legione ready. Gutenberg printed his first book, the Bible, around 1455. 6 There are only twenty-one complete copies of the original Bible. They are some of the 25 most expensive books in the world. In 1987, part of a Gutenberg Bible sold for $5.3 million. 7 Today people remember Johannes Gutenberg. The city of Mainz has a statue of him and a museum. His original printing press is in the museum. (6)They print several pages a day to show that it is in good condition. earoviaU 012mu 394 words/#IN block of wood: type: vrigsypola 01 sind 7 an Oupside down & 下線部 (6) を日本 7. 本文の内容に合わ Many people & Gutenberg g Gutenberg Olt was a long Though Gu cost a lot of Hannes Rotest
