【正文】 ectively speaking, the fastest 4G download speeds in the U. S. top out at an average of Mbps. But by parison 5G promises gigabit (千兆) speeds. “5G is one of those signs, along with artificial intelligence, of this ing data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The selfdriving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data ing from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It39。s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基礎(chǔ)設(shè)施) construction. There39。s lots of data behind that task, which is why we need high speed. Augmented reality glasses and virtual headset haven39。t yet broken the mainstream, but tech panies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because panies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones. Ericsson stated at February39。s Mobile World Congress how smart glasses could bee faster and lighter with a 5G connection, because instead of being weighed down with ponents, the glasses could rely on hardware for processing power. But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.（1）What does the author want to stress in Paragraph 1?

One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they39。ll go away, but I eventually went to the doctor. After examining me, he said, You actually have bad posture (姿勢(shì)). Go off and learn the Alexander technique. Three months later I could walk straighter and sit better. The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercisebased. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly. The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines. So who was Alexander and how did he e up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (聲音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teachertraining school, which is still successful today. So if you39。re walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.（1）What does the author suggest in Paragraph 1? A.She felt no bett
