The new ones are either a bit faster or have a better camera, but they are basically no different from the old ones in our pockets. This is why scientists are hoping, and working for something new. Smart glasses might be the one. Just imagine. Instead of having to pick up your phone and look at the screen, all of the information you need simply appears just in front of you, in your glasses. Satellite navigation (卫星导航) directions would appear right there on the road. And your smart glasses could guide you to the right shelf in the supermarket! Smart glasses could also be used in industry. They could show engineers the instructions they need to fix things more quickly. A doctor could carry out a difficult operation, guided in real time by someone on the other side of the world. This may sound impossible. But most of the technologies needed to invent them are already there. For example, one key technology is called AR. It can make digital 3-D objects appear as if theywere part of the real world. We’ve used it a lot on our video calls. Similarly, huge progress has been made in spatial audio (空间音频). This is when a sound is made to give it a sense of place, like what you hear in an empty room. Some high-end earphones can already do that. Future glasses will of course need to recognise your voice to do tasks. This technology has been widely used in our daily life. So, why haven’t we all worn smart glasses yet? So far, no one has invented a good way to send images (映像) of our world onto glasses. However, with the rapid development of technology, smart glasses could arrive much sooner than we think. ( )4. Why does the writer mention smartphones in Paragraph 1? A. To start a story. B.

V. 任务型阅读 Tom 是小英文报的一名编辑。请你阅读下面材料,帮助 Tom 完成任务。 ( Editor's note: The jobs of today may not be the jobs of the future. 1 _____ )Teleportation（远距离传送）Specialist: Imagine walking onto a teleportation station. Immediately you disappear, and then suddenly you reappear at the place you want to go to. There will be no more cars and no more auto mechanics (机械师). Instead, the teleportation specialist will help you move from place to place. 2_______ Dirigibles (飞船) may change life in much of the world. They’re relatively cheap to work and don’t require expensive airplane runways. They can stop in mid-air to let passengers get off or send goods. Skilled dirigible pilots will be in great need. 3________ More and more people will be taking trips to space and they will need tour guides. One company has already begun a space programme with trips costing about $200,000. In the future, these high prices should become more affordable, and more space guides will be needed. Robot Mechanic: The robots we can use now mostly clean carpets or mow lawns (修剪草坪). Someday these machines will become cheaper, and more families will be able to buy robotic personal helpers. Some people will work as robot mechanics to take care of the mechanical problems of these robots. Task 1: Choose one to complete the editor’s note. 1.____________ A.
