【文章內(nèi)容簡介】 。 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?

He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results.”可知，弗雷德里克亞歷山大，一個出身于186年的澳大利亞演員，在年輕的時候聲音出了問題。他做了分析，意識到自己的姿勢不正確，因此致力于改善姿勢，結(jié)果很好，故可知，他通過矯正姿勢，解決了自己的聲音問題，故選A。 （4）考查主旨大意。本文介紹亞歷山大技巧的對于矯正身體的作用以及其發(fā)明者，故可知在介紹亞歷山大技巧的作用，故選C。 【點(diǎn)評】本題考點(diǎn)涉及推理判斷和主旨大意兩個題型的考查，是一篇科普類閱讀，要求考生根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。5．犇犇閱讀理解 A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them. These items could include weapons, chemicals, laptops and batteries for bombs, the research team said on Tuesday. Research suggested that WiFi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天線)that could be fitted in existing WiFi networks. The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干擾)caused by two factors of objectsthe material and shape. Most dangerous objects such as weapons are usually metal or liquid, which have significant interference, researchers said. When it was tested on a backpack, the accuracy rate topped 95 percent. But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools, the team said, noting its design can inspect bags or luggage without being an exposure to privacy. It uses channel state information (CSI) that is readily available in lowcost WiFi devices. This could have a great impact on protecting the public from dangerous objects, said Yingying Chen, a coauthor of the study, There39。s a growing need for that now. In large public areas, it39。s hard to set up expensive screening equipment like what39。s in airports. Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.” The peerreviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online. Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes, researchers said.（1）What does paragraph 3 talk about?
