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?

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(gè)出身于186年的澳大利亞演員，在年輕的時(shí)候聲音出了問(wèn)題。他做了分析，意識(shí)到自己的姿勢(shì)不正確，因此致力于改善姿勢(shì)，結(jié)果很好，故可知，他通過(guò)矯正姿勢(shì)，解決了自己的聲音問(wèn)題，故選A。 （4）考查主旨大意。本文介紹亞歷山大技巧的對(duì)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(píng)】本題考點(diǎn)涉及推理判斷和主旨大意兩個(gè)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 In our twenties, we find it funny when we can39。t remember our neighbor39。s cat39。s name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it brain freeze. In our forties, we laugh it off as a senior moment and follow up with one of these old age jokes. But the reality is that there es a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, Am I losing it？Or worse, Is this a sign of Alzheimer39。s disease（老年癡呆癥）？ Well, don39。t worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer39。s disease（AD）. The researchers in a new study show that it39。s not forgetfulness but not being aware that we39。re forgetful that we should fear. The researchers began with the assumption that one mon feature of Alzheimer39。s disease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with mild cognitive（認(rèn)知的）damage will progress to fullon AD. For the study, mild cognitive damage was defined as someone whose mental state was considered healthy but who had either plained of memory loss or had suffered objective memory loss. The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with expected, glucose upt
