Ⅰ 记叙文写作
写一个科幻故事
写作指导
本单元的写作任务是写科幻故事。科幻故事是开放式作文的一种，一般会给出一段材料，要求我们充分发挥想象力来拓展原材料的内容，运用逻辑推理的方法，给故事添加开头、结尾或中间过程。想象必须合理且内容丰富，要抓住主题，运用恰当的词汇、句型与语句间的连接成分写出连贯的表达，语言要流畅，且具有美感。
1.仔细审题，确定文章结构
科幻故事的写作一般可分为三部分：第一部分为故事的开始；第二部分为故事发展的过程及结果；第三部分提出故事的教育意义。
2.根据需要确定时态
科幻故事通常发生在未来，因此应以一般将来时为主。若是描述自身“经历”的科幻故事，则多以一般过去时为主。
3.筛选词汇
科幻故事一般为虚构的故事，为了吸引读者，故事的语言要生动、富于虚幻性。

magnificent Tang costumes.Feeling hungry and curious，I went into a restaurant where I came across Li Bai! Then I had a good talk with him and learned a lot about Tang poetry.
One hour later，I pressed the button of “return” and in a few seconds I was lying on my bed.What an amazing experience！
Ⅱ 读后续写
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Back in the early 1980s，the idea of home computers was catching on.I wasn't keen on getting one.Somehow，I evolved and have owned several computers over the years.Some days I loved my computer，but more often than not，I hated it.I didn't grow up with them，and they were a challenge to my mental health.Dealing with modern technology was my introduction to stress，and I know who to blame：my children.
They weren't satisfied that their dad and I finally bought a computer and learned to send emails.We were quite happy with that，but next came a cellphone.Then just talking on the phone was not acceptable；they insisted we learn to text as well.We couldn't get a break.
One social software in particular was popular at the time.Those kids of ours were determined to set up a joint account for us.It took some convincing.We felt no guilt for grating on(激怒) their nerves considering the drama they'd sometimes created for us during their teenage years.A little payback wouldn't hurt those two.
More recently，my husband and I were forced into getting rid of our flip phones and getting smartphones.I will admit that I progressed into appreciating mine.I liked checking my phone and finding out what I needed to know in an instant.I enjoyed having Internet access everywhere I went.I felt a sense of accomplishment；my husband—not so much.To this day，he would happily take back his flip phone.
Last year，our children surprised us with yet another popular form of technology—Alexa.The girls took our smartphones in hand and got us
programmed.Before we fully understood what was happening，we could tell Alexa to turn our lamp on or off，and she would.To be honest，we were a bit annoyed at having to learn how to use yet another device，but we decided to keep it.We mastered turning the lamp on and off，and once again I got the hang of it sooner than my husband did.I became his Alexa coach.
注意：
1.续写词数应为150左右；
2.请按如下格式在相应位置作答。
One night，Alexa did not turn on the lamp when I gave the command.
We should thank our children and grandchildren.
[巧读文]
1.读要素
Who：the author，her husband and children
When：one night
Where：at home
What：Alexa did not turn on the lamp.
Why：They don't know how to use advanced technology clearly.
2.读双线(情节线、情感线)
情节线：
I hated it ...Dealing with modern technology was my introduction to stress ...→came a cellphone→my husband and I were forced into getting rid of our flip phones and getting smartphones → children surprised us with yet another popular form of technology—Alexa
情感线：
stressful → no guilt → a sense of accomplishment → a bit annoyed but decided to keep it
[妙构思]
1.读首句，定方向

由续写第一段首句内容“One night，Alexa did not turn on the lamp when I gave the command.”可知，第一段可描写作者和丈夫对此的不同反应，作者用孩子们教会的技能想到办法解决问题。
第二段：
由续写第二段首句内容“We should thank our children and grandchildren.”可知，第二段可描写作者感受到孩子们教给自己的科技是有用处的，感谢孩子们。
2.巧设问，定细节
第一段：
(1)What did the author do in order to ask Alexa to turn on the lamp
(2)How did the author and her husband feel
(3)What did the author do
She kept telling “Turn on the light”/...
They felt confused/anxious/...
She searched the Internet for information/...
第二段：
(1)Why should the author thank her children
(2)How did the author make her life convenient
(3)How did the author think about advanced technologies
They taught her to use technology/...
She could find a solution on the Internet/accept and use technology/...
They were helpful/convenient/...
[雕句式]
根据提示升级下列句子
1.I tried to say “Turn on the light” to it countless times，but Alexa didn't work.
→ ，Alexa didn't work.(让步状语从句)
Although I tried to say “Turn on the light” to it countless times
2.Our children and grandchildren taught us to use technology so that I could find a solution on the Internet by myself.
→ taught us to use technology so that I could find a solution on the Internet by myself.(强调主语)
3.Our children and grandchildren “force” us to accept and use technology，and it seems to put us under pressure.
→Our children and grandchildren “force” us to accept and use technology， .(非限制性定语从句)
It was our children and grandchildren that
which seems to put us under pressure
[成美文]
One night，Alexa did not turn on the lamp when I gave the command.
We should thank our children and grandchildren.
[参考范文]
One night，Alexa did not turn on the lamp when I gave the command. Although I tried to say “Turn on the light” to it countless times，Alexa didn't work.“New technologies are always unreliable，” my husband complained.I searched the Internet and immediately found the reason why Alexa couldn't work.I just needed to tell Alexa to set the light color to white or whatever color I wanted，and then it would turn on the light.Then Alexa turned on the light itself.
We should thank our children and grandchildren.It was our children and grandchildren that taught us to use technology so that I could find a solution on the Internet by myself.Without them，our life is always invariable and boring.Our children and grandchildren “force” us to accept and use technology，which seems to put us under pressure.
However，the fact is that our children and grandchildren let us really accept and use technology to make our life more convenient.

第一节
1.W：Do you think information technology will replace teachers in 20 years
M：I don't think so.①Teachers will surely use information technology in their teaching. But nothing can replace face-to-face communication.
2.M：What's the headline today
W：A Chinese company launches its own operating system.
M：②I can't believe that.It's really a big breakthrough in Chinese technology.
3.W：Look at the robot sing and dance!
M：That's amazing.③If it could play chess，I would definitely buy one.
W：Sing, dance and play chess.Yes，I would too.
4.M：④Do you support human cloning，Mary
W：④No，but Lucy supports it.She is a scientist.
M：I don't support human cloning either. It's hard for me to accept it.
5.M：Miss Dermott, let me ask you straight away.Do you think, within a few years, many people could work at home instead of working in offices
W：Oh, yes. It's happening now. You see，⑤the communication industry has made such progress in the last ten years.

M：Sure, go ahead.
W：Oh, isn't your computer Wi-Fi capable
M：You want to go online There are no Wi-Fi hotspots around.
W：⑥Oh, no Internet access is killing me.
M：Can't you wait till you get home Then you can surf the Internet using the broadband, wireless connection or whatever you like.
W：No, I'm not feeling myself. I just want to check my emails, visit my favorite websites and chat with my friends. I just can't bear losing track of all the latest information. It almost drives me crazy.
M：⑦Then, you're probably addicted.

听下面一段对话，回答第8和第9小题。
W：Do you know, Jack ⑧Scientists in Antarctica have used a new invention to help them study seabirds closely—a tiny robot on wheels that looks like a baby bird.
M：Yes. I once saw it on TV. The robot is similar to those used in the exploration of the moon. Scientists, working some distance away, controlled every movement the robot made.
W：You're right.⑨It was immediately accepted by seabirds' families as one of their own. The adults even sang to it, though to their disappointment, the “baby” didn't reply.
M：That's funny! Scientists are now working on a new model with one important improvement—it will be able to play seabird songs.

W：Yeah. So，⑩I reported it to my bank manager and he told me not to believe it.But who sent those messages
M：I have no idea. But I've heard many people saying they've received such messages. I guess those guys are organized.
W：Why did they do this
M：To steal personal information and make money. They could get your account number, credit card number, or even your password if you visit a certain website with your cellphone.
W：That's so scary.
M： But don't worry. Most websites have protection measures like firewalls and so does your cellphone. So it's pretty safe to log on there.

M：How did you get here You've never been here before.
W：My car had it all mapped out for me.
M：So， you've used AI at least twice before you came here—online shopping and getting directions. And you'll probably use it several more times this weekend.
W：That's interesting. Why are you interested in this stuff all of a sudden
M：I just never realized how much it affects our day-to-day lives. Plus， my parents just got this.
W：What's that
M： It's a little sweeping robot.It sucks up all the dust on the floors and cleans up small water spots.Do you see how it didn't hit into the fridge That's because it has a camera that tells it where the fridge is. Isn't that crazy
W： Not really.I have the same technology in my new car. Hey, do you want to see a movie
M：Sure, but I don't know what's playing.
W：That's OK. I'll just ask my watch. Hey，what movies are playing today
(13.A　14.C　15.B　16.C)
听下面一段独白，回答第17至第20小题。
W：Hey，welcome to today's talk！ I'm Emma Davis, an AI enthusiast who's been exploring this since finishing at MIT.I'm excited to share my passion for the incredible world of artificial intelligence, or AI.I'll kick things off with an awesome story from 2015, in Silicon Valley. Our project was called “Project Skylark”.And with Dr. Jack Thompson, a Cornell University bird expert， we wanted to teach a machine to recognize different birds.It was amazing. “Avis”， the AI system,
learnt to improve its accuracy over time. In six months, it could identify bird species better than human experts! This showed the incredible potential of AI! It's a long way since the 1950s with Alan Turing's ideas. Modern systems can analyze data, spot patterns, and make decisions on their own. This power has opened up endless possibilities in areas like healthcare, finance, and transportation. One inspiring example comes from Dr. Alice Chen, who in 2018 led a team at Stanford University to develop the computer program “MediScan” that analyzes images
and detects early signs of diseases like cancer.MediScan's accuracy and speed massively surpassed human capabilities, saving thousands of lives. However, it has its challenges and risks. A 2020 report showed concern of AI taking jobs and affecting economy. I love AI but there's tough conversations about balancing progress, job security, privacy and security as systems get better. Together, we can create a future where AI helps us achieve our wildest dreams.

【语音技巧】
不完全爆破
不完全爆破是连贯语流中自然产生的语音现象，出现在一口气读完的一个语音单位内，即单词内部或一组意义上和语法上紧密联系的词。它分为3种情形。
1.英语音标中，辅音/p/、/b/、/t/、/d/、/k/、/ɡ/是爆破音。当一个爆破音的后面紧跟着另一个爆破音时，前一个爆破音只按其发音部位做好发音口形、形成阻碍，而不爆破出来，稍微停顿后立即发出后面的辅音，这种现象称为不完全爆破。例如：
2.英语音标中还有一种摩擦音，它们是/f/、/v/、/s/、/z/、/h/等，当爆破音后面紧跟着摩擦音时，只有轻微爆破，也称为不完全爆破。例如：
3.爆破音后面紧跟鼻音/m/、/n/或舌边音/l/时，也会形成不完全爆破。 例如：
