Unit 2.1 Starting out & Understanding ideas(Ⅰ)-【创新教程】2025-2026学年高中英语选择性必修第二册五维课堂Word课时作业（外研版2019）

Ⅰ.阅读理解 A Last month，I began my own two­week­long digital detox.I got the inspiration from the tech writer Paul Miller，who got away from the Internet for a whole year.It was not worth mentioning as against the time Miller spent offline，but it was the longest I had gone through without almost any Internet in 13 years. Why did I do it？For a while I felt the urge to try fully disconnecting to free myself from the endless work.I wanted to take a break from it all for a couple of weeks at least to see what would happen.After all，throughout the last decade，I've been online 24—7，overreacting to my email inbox and social feed (传送)－living in a world where the line between the digital world and the real world gets a bit unclear at times. I haven't of course forgotten that I'm CEO of a social media company.My work is built around the premise(前提)that being connected makes our lives richer，more rewarding and more efficient.Still，I'd forgotten one key lesson along the way：　moderation　.As more and more of my life was spent scanning social feed and checking out my inbox，I realized that I needed to step back and get a whole new perspective. So on my winter vacation to Mexico，I took a break from being active on the Internet for the entire trip.For the whole 14 days，I ate a lot of delicious fish tacos，surfed and fixed up my cottage on the beach.I didn't write or send any emails.I didn't scan any Top 10 lists of feed.The one I did give myself was checking my email inbox occasionally－just to make sure an emergency wasn't unfolding while I was away. What I learned from my short experiment was actually not too unlike what Miller learned.I didn't end up discovering that technology is evil.In fact，I found myself reflecting on how technology over the last few years had let me experience some of the most rewarding and eventful moments of my life.

The study examined the home Internet use，well­being(幸福)and behaviour of 296,000 15­year­olds in 41 countries.More than one in four spent more than four hours per day online outside of school.The study found lower levels of well－being among students who spent more than six hours per day online.They were twice as likely as teenagers spending one and two hours per day online to report that they felt lonely at school.These “extreme Internet users” were also especially at risk of “behaving in problematic ways at school，such as arriving late or skipping class”． The report said，“Lower levels of engagement(密切关系)with school may be connected to less sense of belonging at school.It is also possible that skipping class and arriving late for school are the consequence of lack of sleep among extreme Internet users.” It adds，“Parents，schools and health professionals can work together to watch and plan children's use of new media.” The study also found that countries that invest (投资)heavily in Information and Communication Technology (ICT) in schools have seen no “considerable” difference in 15­year­olds achievement in reading，math or science tests.The study results suggest “limited” use of computers at school “may be better” than not using them at all.However，students who use computers “very frequently” at school “do a lot worse in most learning outcomes”．The report says, “In the end，technology can strengthen great teaching，but great technology cannot replace poor teaching.” [语篇解读]　本文是一篇说明文。文章主要介绍了一份研究报告，在校期间上网时间超过6小时的青少年更容易感到孤独、逃学。 5．The international study showed that ________. A．half of the students spent six hours online every day B．extreme Internet users had lower levels of well­being C．teenagers spent much time online when they felt lonely D．most of the students were late for school after extreme Internet use 解析：B　[细节理解题。根据文章第二段的The study found lower levels of well­being among students who spent more than six hours per day online，再结合下文可知These “extreme Internet users”这些极端网民指的就是每天上网时间超过6小时的学生，即极端网民的幸福感较低。B项符合以上说法，故选B项。] 6．What can we learn from the study results? A．Schools should invest more in ICT. B．Proper use of computers is helpful at school. C．Technology sometimes leads to poor teaching. D．Computer users perform well in maths at school. 解析：B　[推理判断题。根据文章最后一段的The study results suggest “limited” use of computers at school “may be better” than not using them at all.However，students who use computers “very frequently” at school do a lot worse in most learning outcomes可以推知，在学校正确使用电脑是有帮助的。B项符合以上推测，故选B项。] 7．Where does this text most probably come from? A．An engineer textbook. B．A personal diary. C．A science news report. D．A computer book. 解析：C　[推理判断题。根据文章的结构和文章第一段的Teenagers who spend more than six hours online on school days are more likely to be lonely and skip school，according to an international study.可知本文主要介绍了一份研究报告，属于科学新闻报道类阅读，故推测该文很有可能出现在科学新闻报道上。故选C项。] Ⅱ.阅读七选五 __1__ Moving from high school into college can be especially different because of the freedom students experience in college along with a new set of expectations.
