（2019·浙江杭州·一模） The "best years of your life" Maybe not, but you can learn to make the most of your high school days.
1. Learn to appreciate small things. Whether it's having a computer, having friends, having a good supply of food, a bed to sleep on, family that loves you, having a decent education or simply being born in this world. Remember that the point of life is for you to enjoy it. 26． Remember that these are the last few years you will be able to enjoy yourself without having to worry about the responsibility of an adult, but make sure you prepare yourself for when you do become one. When you actually become an adult, you'll learn to love that responsibility and you probably never want to go back.
2. 27．. Unlike what many articles state, you don't have to be popular and have a gazillion friends to be happy. In fact, many of the "friends" you have when you are popular are not true friends. Try to have friends that like you who you are, not just because you are wearing a certain brand of shoes or something like that. These are people who shop at the same store as you; not someone who will sympathize with you when your dog dies.
3. Keep your grades up. 28．This also sets you up to get into a college you want to go to, which in turn prepares you for a career you will enjoy, improving your quality of life in the future. You'll get cheap car insurance as well if you have at least a B or A average.
4. 29．. Participating in clubs, activities, and sports increases your chances of meeting new friends. While you only need 4 or 5 close friends, that doesn't mean you shouldn't try to meet new people. Participating gives you something to do instead of sitting bored at home and wallowing in self-pity.
5. Work at a job you can enjoy. Working is a great way to gain experience and to meet other people. 30．This will look great on your resume. If you can't find work, especially in this hard economic time, volunteer or make your own job.
A．You should also find a hobby that is meaningful or practical.
B．Be happy, and life will reward you.
C．There is nothing more satisfying than seeing your hard work pay off in the form of A's and B's (but mainly A's).
D．Choose your friends wisely.
E. When you do get out of college, interviewing companies will look at your prior work experience.
F. Be sociable.
G. Even though you want to enjoy your teen life as best as possible, don't slack off in school.

Passage 1
（2021·浙江·宁波市鄞江中学高二阶段练习）
6 ways our post-pandemic (疫情后) world will be different
The future has never been easy to forecast, and the coronavirus makes life even more unpredictable. To gather informed views on how we most likely will live, learn, work, and communicate when we reach the new normal, National Geographic interviewed a range of experts and leaders.
New Ways to Learn
1． Although equal access to tech remains a barrier, tools will be designed that may bridge divides. Students will use technology to help with homework, set goals, and measure progress.
Balance Work and Life
The future of work won’t be fully remote, but it won’t be limited to offices, either. It’ll be a mixture. Smaller offices will be centers for occasional in-person collaboration, while improved digital tools—such as better video chatting—will support workers at home. Besides, more emphasis on balancing productivity with personal needs will allow employees to organize their work hours to fit their schedules. 2．
Tech Leads the Way
Broadband(宽带) access has never been equal. 3． Yet advances in high-speed 5G telecom networks will fuel an increase in fields from telemedicine to banking, education, and transportation. This will be a tidal wave of change. More efficient networks will reduce costs and help small businesses affected by the pandemic reach new customers and grow.
Get Out and Stay Out
U. S. national parks saw dramatic drops in visitors last spring—but then numbers exploded this spring, as did sales for RVs and bikes. 4． People are going outdoors more often this year and also shifting from adventure sports requiring travel—skiing, climbing, backpacking—to closer-to-home activities such as bird-watching, gardening, and bike riding.
5．
Public concern in the United States about global warming hit an all-time high last November, according to researchers at Yale and George Mason Universities. Large majorities of Americans think human-caused global warming is real, and they feel worried and even personally responsible. Surprisingly, a survey in April found that COVID-19 hadn’t replaced concern over the climate—though it had reduced media coverage of it.
A．Remote Possibilities
B．One Planet, Two Crises
C．Therefore, flexibility will be the ultimate job benefit.
D．The pandemic exposed that divide.
E.One positive aspect of schools closing may be how districts are innovating to improve learning from home.
F.Many cities have closed streets to make room for outdoor dining, public events, and parks.
G.The Internet has made it possible for millions of people to work remotely, but it’s put us at risk of cyber- attacks.
七选五专练216
（2021·全国·高三专题练习） Slowly but surely, we're moving closer to the super-fast 5C world that tech companies have been promising us for years. But do we really know it all 6．
◆It's not quite here yet.
Though we've seen a lot of positive progress, we still have a long way to go before 5G is anywhere near as available as 4G is right now. But most in the industry agree that 2020 is the earliest when 5G will ever begin to touch most consumers. And even then, early 5G networks could come with their fair share of growing pains.7．
◆It's not going to be cheap.
8．Some companies haven't commented on specific pricing yet, but, as most have pointed out, data costs have historically climbed as network speeds increase. There's little reason to think that trend won't continue. It's not all bad news, though. Experts are optimistic that data prices will come down in the long run once 5G starts to be widely available. But it's impossible to say how long that change could take.
◆9．
It's obvious that 5G networks will bring fast data connections. However, part of its appeal is that it makes It's obvious that 5G networks will bring fast data connections. However, part of its appeal is that it makes mobile networks better, meaning that networks can support many more data connections than what was previously possible. Have you ever been to an event where your data connection slowed down or stopped working 10． But 5G networks have a much higher ability to support up to a million devices per square kilometer.
A．It's really, really fast.
B．It's not just about speed.
C．Extra speed comes at a higher cost.
D．Here are three major disadvantages of 5G.
E.Let's clear out some misunderstandings about it.
F.That's because present networks can easily be overloaded.
G.Unbalanced coverage or negative effects on battery life may arise.
七选五专练217
（2020·广东·珠海市第一中学高二开学考试）Forging a 5G future
The future in sci-fi movies seems so close, yet so far away. Delightfully, 5G technology makes that future look easily achievable. Schools, hospitals, transportation, factories—even our homes will soon use this powerful wireless network. Last year, China started testing 5G mobile networks in its several cities. So what is 5G It's the latest generation of cellular (蜂窝状的) network technology. 11．
5G's benefits mainly come from speed and connectivity (连接).12．People will be able to use the Internet at a much greater speed than before. Imagine being able to download an entire movie in just a few seconds! That's how fast 5G will be.
13． For example, one of the biggest problems with developing driverless cars is the delay between sending a signal and receiving it. Driverless cars must be able to react instantly to sudden changes in their environment, such as a dog running across the road. This will require these cars to send and receive huge amounts of data within milliseconds (毫秒).14． It will also allow doctors to perform operations remotely, using robots. The robots will respond more quickly to the doctors’ movements.
So what about 5G's connectivity 15．. Imagine having a smart home that automatically turns the lights on when you open your front door.
"New things become possible when you can move information at a massive scale," Gordon Smith, CEO of telecom equipment reseller Sagent, told The Telegraph. "5G becomes the great enabler. "
No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.
A．We may develop "smart" environments with it.
B．Such speed helps other technologies, too.
C．5G will make this possible.
D．It connects people's lives in various ways.
E.It is faster and more stable than 4G, the previous generation.
F.With 5G, people can conveniently solve many problems.
G.The advantage of higher speeds is obvious.
七选五专练218
（2021·广东·梅州市梅江区嘉应中学高二阶段练习） Whether through advertisements, news articles or social media posts, most of us by now have started hearing about the upcoming data network of the future. What is 5G
16． To help all of us understand them, we have listed some facts everyone should know.
● First, what is 5G
5G is the 5th generation network. It is a new global network after 1G, 2G, 3G and 4G, which can connect everyone and everything together. 17． With 5G there is a possibility that we can do everything.
●18．
Self-driving cars, which will depend on ultra-fast data transmission speeds to communicate with other cars as well as their surroundings, promise a safer transportation system if and when technology is fully realized.
●5G will change the way we work or study.
In the post-coronavirus world, having remote working capabilities will be more important than ever. Video meeting, e-learning and other Internet-enabled work applications will be possible to the point where people can use them as easily in their home or on the road as in the office or classroom. 19．
●5G will change society in too many ways.
The use-cases and applications widely talked about are only a part of what 5G will make possible. Just as in the early days of the Internet in the 1990s, few foresaw the rise of useful websites like Wikipedia, org. The same will surely be true of 5G.
With 5G, other technologies don't seem like a dream anymore. 20． Now say goodbye to 4G in your homes and be prepared for the new wave of 5G.
A．Self-driving will grow popular.
B．5G will help make self-driving cars a reality.
C．The computer game players can have a faster speed.
D．Why does 5G matter so much in people's daily life
E.The power to do anything we want will be at our fingertips.
F.5G means faster data speeds and ultra-low latency （超低延迟）.
G.It will be also easier for doctors to treat patients remotely by 5G.

（2020·安徽淮北·二模）The Tech That Will Invade Our Lives in 2020
The 2010s made one thing clear: 21．It is in our homes with thermostats that heat up our rooms before we walk through the door.It is in our cars with safety features that warn us about vehicles in nearby lanes.We even wear it on ourselves in the form of watches that monitor our health.Here's what to watch in tech this year.
22．
In the last few years,Amazon,Apple and Google have battled to become the center of our homes.Now,they are working together on a standard to help make smart home products work well with one another.For example,if you open your door,then the door can say to the lights to turn them on.
5G rises steadily.
One important benefit of the technology is its ability to greatly make everything faster. 23．That will be important for the compatibility(兼容性）of next-generation devices like robots. sell-driving cars and drones.For example,if your car has 5G and another car has 5G,the two cars can talk to each other.24．
The wearables market heats up.
It is a time of intense competition in wearable computers.25．Computer chips are making their way into other electronic products like earphones,which means that companies are likely to introduce innovations in wearable equipment,That whole area of improving our hearing and hearing the way other people hear us is really interesting.

七选五专练220
（2021·福建·厦门市杏南中学高二期中） To help you understand what 5G is, and what it means to you, we’ve put together a handy guide here.
What is 5G
26．At its most basic level, 5G will be used to make calls, send texts, and to simply get online. But it’s going to be significantly faster than previous generations, and could open the door up to a range of exciting new uses.
27．
5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands are faster, they don’t carry information as far. That’s to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity（容量）.28．
Why is it better than 4G
5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver peak download speeds of around 300 Mbit/s.29．In real life, this could allow you to download a full HD film in less than 10 seconds!
30．It means there will be very little—if any—delay when you carry out tasks on a device. While this will help improve things like gaming experiences, it could also pave the way for safer self-driving cars—in which even a short delay could be life-saving.
Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.
A．How does 5G work
B．How will 5G affect you
C．5G is also expected to have a lower latency.
D．5G is short for “5th generation mobile network.”
E.In comparison, 5G could offer download speeds of over 1 Gb/s.
F.Therefore, the similarity between 5G and 4G technology is huge.
G.This means 5G will support up to 1,000 more devices per meter than 4G.

6 ways our post-pandemic (疫情后) world will be different
The future has never been easy to forecast, and the coronavirus makes life even more unpredictable. To gather informed views on how we most likely will live, learn, work, and communicate when we reach the new normal, National Geographic interviewed a range of experts and leaders.
New Ways to Learn
1． Although equal access to tech remains a barrier, tools will be designed that may bridge divides. Students will use technology to help with homework, set goals, and measure progress.
Balance Work and Life
The future of work won’t be fully remote, but it won’t be limited to offices, either. It’ll be a mixture. Smaller offices will be centers for occasional in-person collaboration, while improved digital tools—such as better video chatting—will support workers at home. Besides, more emphasis on balancing productivity with personal needs will allow employees to organize their work hours to fit their schedules. 2．
Tech Leads the Way
Broadband(宽带) access has never been equal. 3． Yet advances in high-speed 5G telecom networks will fuel an increase in fields from telemedicine to banking, education, and transportation. This will be a tidal wave of change. More efficient networks will reduce costs and help small businesses affected by the pandemic reach new customers and grow.
Get Out and Stay Out
U. S. national parks saw dramatic drops in visitors last spring—but then numbers exploded this spring, as did sales for RVs and bikes. 4． People are going outdoors more often this year and also shifting from adventure sports requiring travel—skiing, climbing, backpacking—to closer-to-home activities such as bird-watching, gardening, and bike riding.
5．
Public concern in the United States about global warming hit an all-time high last November, according to researchers at Yale and George Mason Universities. Large majorities of Americans think human-caused global warming is real, and they feel worried and even personally responsible. Surprisingly, a survey in April found that COVID-19 hadn’t replaced concern over the climate—though it had reduced media coverage of it.
A．Remote Possibilities
B．One Planet, Two Crises
C．Therefore, flexibility will be the ultimate job benefit.
D．The pandemic exposed that divide.
E.One positive aspect of schools closing may be how districts are innovating to improve learning from home.
F.Many cities have closed streets to make room for outdoor dining, public events, and parks.
G.The Internet has made it possible for millions of people to work remotely, but it’s put us at risk of cyber- attacks.

（2021·全国·高三专题练习） Slowly but surely, we're moving closer to the super-fast 5C world that tech companies have been promising us for years. But do we really know it all 6．
◆It's not quite here yet.
Though we've seen a lot of positive progress, we still have a long way to go before 5G is anywhere near as available as 4G is right now. But most in the industry agree that 2020 is the earliest when 5G will ever begin to touch most consumers. And even then, early 5G networks could come with their fair share of growing pains.7．
◆It's not going to be cheap.
8．Some companies haven't commented on specific pricing yet, but, as most have pointed out, data costs have historically climbed as network speeds increase. There's little reason to think that trend won't continue. It's not all bad news, though. Experts are optimistic that data prices will come down in the long run once 5G starts to be widely available. But it's impossible to say how long that change could take.
◆9．
It's obvious that 5G networks will bring fast data connections. However, part of its appeal is that it makes It's obvious that 5G networks will bring fast data connections. However, part of its appeal is that it makes mobile networks better, meaning that networks can support many more data connections than what was previously possible. Have you ever been to an event where your data connection slowed down or stopped working 10． But 5G networks have a much higher ability to support up to a million devices per square kilometer.
A．It's really, really fast.
B．It's not just about speed.
C．Extra speed comes at a higher cost.
D．Here are three major disadvantages of 5G.
E.Let's clear out some misunderstandings about it.

（2020·广东·珠海市第一中学高二开学考试）Forging a 5G future
The future in sci-fi movies seems so close, yet so far away. Delightfully, 5G technology makes that future look easily achievable. Schools, hospitals, transportation, factories—even our homes will soon use this powerful wireless network. Last year, China started testing 5G mobile networks in its several cities. So what is 5G It's the latest generation of cellular (蜂窝状的) network technology. 11．
5G's benefits mainly come from speed and connectivity (连接).12．People will be able to use the Internet at a much greater speed than before. Imagine being able to download an entire movie in just a few seconds! That's how fast 5G will be.
13． For example, one of the biggest problems with developing driverless cars is the delay between sending a signal and receiving it. Driverless cars must be able to react instantly to sudden changes in their environment, such as a dog running across the road. This will require these cars to send and receive huge amounts of data within milliseconds (毫秒).14． It will also allow doctors to perform operations remotely, using robots. The robots will respond more quickly to the doctors’ movements.
So what about 5G's connectivity 15．. Imagine having a smart home that automatically turns the lights on when you open your front door.
"New things become possible when you can move information at a massive scale," Gordon Smith, CEO of telecom equipment reseller Sagent, told The Telegraph. "5G becomes the great enabler. "
No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.
A．We may develop "smart" environments with it.
B．Such speed helps other technologies, too.
C．5G will make this possible.
D．It connects people's lives in various ways.
E.It is faster and more stable than 4G, the previous generation.
F.With 5G, people can conveniently solve many problems.
G.The advantage of higher speeds is obvious.

七选五专练220
（2021·福建·厦门市杏南中学高二期中） To help you understand what 5G is, and what it means to you, we’ve put together a handy guide here.
What is 5G
26．At its most basic level, 5G will be used to make calls, send texts, and to simply get online. But it’s going to be significantly faster than previous generations, and could open the door up to a range of exciting new uses.
27．
5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands are faster, they don’t carry information as far. That’s to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity（容量）.28．
Why is it better than 4G
5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver peak download speeds of around 300 Mbit/s.29．In real life, this could allow you to download a full HD film in less than 10 seconds!
30．It means there will be very little—if any—delay when you carry out tasks on a device. While this will help improve things like gaming experiences, it could also pave the way for safer self-driving cars—in which even a short delay could be life-saving.
Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.
A．How does 5G work
B．How will 5G affect you
C．5G is also expected to have a lower latency.
D．5G is short for “5th generation mobile network.”
E.In comparison, 5G could offer download speeds of over 1 Gb/s.
F.Therefore, the similarity between 5G and 4G technology is huge.
G.This means 5G will support up to 1,000 more devices per meter than 4G.
