1 . 阅读下面材料，在空白处填入1个适当的单词或括号内单词的正确形式。

Technology is changing the face of the world, and now faces are changing technology too. Facial recognition technology,     1     its capacity to analyse a huge amount of data, has come into widespread use. It works by comparing the facial features of     2     (give) images with what are in a database. It offers a quick and cool alternative to traditional passwords, and you cannot forget your own face! In theory, networks which use our own body as passwords should also be     3     (safe) from hackers and better protect us from identity theft than those who use traditional passwords, mainly because every individual is unique. This technology is     4     (especial) useful in public places: banks, airports and railway stations, to name but a few.

However, facial recognition technology has also started to pose some difficult questions. Experts have been giving     5     (warn) about this technology, saying it may not be as good as we think. Facial expressions often vary,     6     (make) facial recognition less effective. Moreover, there is growing concern     7     we might fall victim to this technology, as there are cases in which hackers have broken into facial recognition systems by using people’s social media photos     8     (build) models of their faces.

Scientists and engineers     9     (urge) to improve existing technology and make it fail-safe in recent years. Apparently, this will be     10     tough task. Whatever happens, we need to make sure that facial recognition technology can be trusted—or we will have to face the consequences.

5 . Technology is widely available to students in classrooms across the United States, a new study shows. Nearly nine in ten U. S. public school students say they use digital learning (数字化学习) tools at least a few days a week. And more than half of those who were questioned said they used digital technology to learn.

In the new survey, digital learning tools means technology. It includes websites, application software programs, and online classes, games, videos and programs. The survey found that classroom technology gets high marks from educators. At least eight in ten teachers and school leaders say they see great value in using classroom technology tools now and in the future.

When it comes to preparing students for future careers (职业), the study found that educators are likely to say technology is more effective than non-digital tools for connecting learning to students’ careers.

Derek Kelley of Virginia agrees. He manages technology for Fairfax County Public Schools, which serves nearly 200,000 students. He said, “The important thing is to help prepare the students for real world experience and knowledge about technology is something students need.”

In the report, more than half of the special education teachers questioned said technology could help their students. Tony Daniel, a special education teacher, agrees with that. He teaches children with learning difficulties at the Springfield Estates Elementary School in Springfield, Virginia.

Nearly all pupils say digital learning tools are fun. Most say the technology helps them learn things on their own and at their own speed.

Almost three-fourths of secondary students say the technology tools help them learn things on their own. Over 50% said they make school more interesting. 42% would like to use it more often at school, and only 8% said they would like to use them less. One thing everyone agrees on is that technology is here to stay in American classrooms.

7 . To help you understand what 5G is, and what it means to you, we’ve put together a handy guide here.

What is 5G?

    1    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.

    2    

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(频段) 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).    3    

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 传输)peak(峰值)download speeds of around 300 Mbit/s.    4    In real life, this could allow you to download a full HD film in less than 10 seconds!    5     It means there will be very little—if any—delay when you carry out tasks on a device(设备). While this will help improve things like gaming experiences, it could also pave(为…铺平道路)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 lag(延迟).

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.

The app has a base of 12, 000 questions developed by teachers using the Australian, British and American curriculums designed for primary school children.
