Next-generation fitness equipment and robots help you cook dinner. Those are a few of the countless new products expected to be shown next week at CES, the annual tech conference that typically sets the tone for the biggest trends of the year. Home automation, health and 5G will once again be hot topics, but many companies will also introduce pandemic-specific features to reflect our increased time at home.

Each year, reporters, exhibitors and investors typically explore Las Vegas showrooms filled with giant TVs, smart cars and robots, but CES will be online only for the first time in its 54-year history due to Covid-19.

The Consumer Technology Association, the nonprofit behind the four-day event starting Monday, said 1,800 exhibitors from around the world will fill its "digital venue" this year—a number that's down significantly from 4,000 in-person exhibitors last year. The move will allow tech companies from countries which have never attended before to take part in the online exhibition, but could also make it harder for smaller companies to get noticed without a physical showroom.

Registered attendees will be able to stream and re-watch keynotes from companies such as Verizon (VZ) and General Motors (GM), tune in to breakout sessions — about how, for example, technology is playing a role in vaccine deployment—and search through a registry of exhibitors to watch new product presentations.

It'll lack some of the signature ingredients of the trade show, such as hands-on time with the latest small machines and networking. But the technology that makes our lives more connected and convenient will still gain popularity.

1. What are the new products mainly connected with?
A.People’s daily life.B.Everyday busy work.
C.The popularity of 5G.D.Countless housework.
2. What do we know about the tech conference?
A.It takes place every two years.B.It attracts fewer exhibitors this year.
C.It is held mainly on the Internet.D.It prohibits small companies to attend.
3. What’s the author’s attitude towards the move?
A.Supportive.B.Disappointed.C.Doubtful.D.Casual.
4. Where are the text possibly from?
A.A brochure.B.A textbook.C.A newspaper.D.A guidebook.

【推荐1】Support for renewable energy technology to figllt global warming is weakening in the face of worldwide economic problems and the true scale of the carbon reductions required,a survey published today has suggested.
Figures presented at the UN climate talks in Poznan,Poland,show that climate experts have less faith in alternative energy than they did 12 months ago.
The survey shows less support for wind energy,solar power,biofuels,biomass and hydrogen energy as technologies with “high potential” to reduce carbon levels in the atmosphere over the next 25 years.
Eric Whan of Globesean,which carried out the survey of “climate decision makers”.Said, “As the climate crisis deepens they could be becoming less optimistic that individual technologies may be able to solve the problem.’’
The survey,supported by groups including the World Bank,the United Nations Environment Programme and the Pew Center for Global Climate Change,questioned l,000 senior figures across governments,pressure groups and companies in 115 countries over the last few weeks.
Almost three quarters of the experts agreed in the survey that “equitable(公平的,平等的) economic growth and development and significant progress in combating(与……斗争)climate change can be achieved at the same time.’’
Asked to rate the likely Success of low-carbon technologies in the midterm,they showed less confidence than a similar survey 12 months ago.Support for offshore wind farms,was down 61%from 65%last year.Solar electricity generation was rated as having high potential by 66%of   respondents,down from 74%.Support for hydrogen power was 32%,down form 36%in 2007.
The respondents also warned that a deep recession(衰退)would make a new global deal on climate harder to achieve.Some 44%agreed that the current economic crisis will significantly delay or compromise the “achievement of effective climate change agreements.’’

【推荐2】It is in human nature to explore new things. To that end, many countries have been exploring space for many decades, particularly the US, Russia, and countries in Europe.

President Xi Jinping praised the success of the Chang’e 5 mission (使命) in bringing back the country’s first samples (样本) collected from the moon. The whole country is proud of this breakthrough. The Chang’e 5 mission has achieved many significant breakthroughs, including China’s first lunar (月球的) surface sampling, first liftoff from the moon and the first spacecraft with the ability to gather and meet in lunar orbit with samples to re-enter the Earth s atmosphere.

The success of the Chang’e 5 mission marks a conclusion of China’s current lunar exploration project. The successful re-entry and landing of the Chang’e 5 capsule (太空舱) have enabled China to obtain its first lunar samples, marking a new start for lunar and planetary research. With this achievement, China sets a new milestone in space exploration.

No matter how far China goes into space, it always stays true to its original mission-uncovering the secrets of the universe and contributing to human’s peaceful use of space. China is a peace-loving country and will use its achievements for promoting peace around the globe.

China views these efforts as part of the world’s lunar exploration. It chose a different landing site and is promising to share its samples to enrich the planet’s knowledge. Some foreign scientists have shown particular interest. The exploration is not for commercial purposes, but international scientific research. Human beings shall explore the moon together, as it will finally need large projects requiring international cooperation. China will play a leadership role in the international scientific community.

文章大意:本文是一篇记叙文。文章讲述了作者用VR为学生提供沉浸式课堂并受到学生的欢迎的故事。

【推荐3】I had heard about VR (虚拟现实) being used in the classroom but didn’t think I’d ever try it. I actually got a VR headset (耳机) as a New Year present from my friend and started searching for apps online to see whether it could be useful in my classroom. I soon found a free app through Google Cardboard and knew I had a lesson!

To use VR in the classroom, you need two things: a smartphone that can download the app or video, and a headset. To find the actual videos we’d be watching, I searched through free VR apps like Orbulus, Trench Experience VR and Cardboard. I also found hundreds of videos on YouTube. The key is to find videos made with the 360 cameras. While they don’t give the kids a 3-D experience like the apps, they are still amazingly immersive ( 沉浸式虚拟现实的) when viewed through the headsets.

So far we’ve had three lessons. I first used the headsets with my seventh grade U. S. History class. The Trench app allows students to “walk” through a trench (战壕) during World War I and learn about many of the tools used during that time. My second activity was working with the sixth grade Geography class. They used the headsets strictly as viewers to watch a 360 video taking them through a rocky landscape. My final activity was the most interesting one, according to the reactions (反应) of my eighth grade Civics students. I was able to find a White House 360 tour that was made a few years ago.

For the rest of this year, I plan to continue using apps and 360 videos in my classes. Next year I’m going to write to my boss asking for a 360 video camera so that I can begin to create my own VR field trips for the students.

1. When did the author get the idea of trying VR in her classroom?
A.When she was searching for apps online.
B.After she received a VR headset as a gift.
C.When she was having a conversation with her friend.
D.After she heard about VR being used in the classroom.
2. What does the underlined word “they” in Paragraph 2 refer to?
A.The kids.B.The apps.
C.The videos.D.The headsets.
3. Which VR lesson was the most popular one among students?
A.The Civics lesson.B.The Science lesson.
C.The Geography lesson.D.The U.S. History lesson.
4. What will the author do next year?
A.Buy a 360 video camera.
B.Create 360 videos by herself.
C.Take her students on more field trips.
D.Try new teaching methods in her classes.
