Electronic book（電子書籍） とe-reader（電子書籍リーダ）の違いはなんですか？ わかる方いらっしゃったら教えて欲しいです🙇‍♀️ ⬇️読んでもいまいちよく分かりません

6 次の英文を読み、 下記の問題に答えなさい。 OF Electronic books have been available for years. Consumers can (7)purchase and download them from the Internet. However, until now, an electronic book had to be read on a computer. Computer screens can cause eye strain and they are not as portable as a book. (1), most people have not chosen to get electronic books. However, that may be about to change because of advances in electronic book display technology. New display devices, called e-readers, allow people (). They are small, lightweight and can easily fit into a bag or purse. Some manufacturers are even making flexible displays. What's more, the screens are bright and easy to read. Competition between e-reader manufacturers is heating up as the market for electronic books grows. E-readers appeal to a number of different markets. One of the biggest markets is business people. Many e-readers have the ability ( I ) through a wireless Internet connection. This will allow business people (). These devices also appeal to frequent travelers. Instead of packing books in a suitcase, a traveler can simply download books and read them on the device. E-readers also

Unfortunately, that's not true, even in highly developed countries! 稼ぐ Let's focus on the workplace ( A ) women often do not get equal treatment. They earn (¹)( ) than men, even when they do the same job They are promoted (1) ) often than men. That's (B) there are still fewer women in top positions. C There is also the problem of maternity leave and job security. Many American women are not paid during maternity leave. Their job is protected only for 12 weeks after childbirth. If they take more time off, they may be out of a job! Clearly this situation is unfair. What can we do to achieve gender equality? 昇進 First of all, (2)(1. the way 2. behave 3. change 4. at work 5. should 6. men 7. they).

Second, women have to change their behavior in the workplace. express their opinions. They should remember that it's OK to disagree. they have to act like leaders---strong, positive and polite. Third, companies should have plans that promote gender equality such as paid maternity leave, flexible working schedules and working from home. Gender awareness programs are also helpful. Gender equality in the workplace is not an impossible dream, but it will take time, energy and understanding to reach this goal. 【】 gender equality maternity leave childbirth 1 less equal treatment 「平等な待遇」 promote 「昇進させる」 job security 「雇用保障、 仕事の保証」 (質問) 1. 空欄 (1) に入れるのに最も適切なものを①~④より選び、その番号を解答欄に記入し なさい｡ 2 least • gender awareness programs 「性別に関する啓発活動」 ( 2.
