課時跟蹤練(三) Lesson 2 & Lesson 3 Pre reading.閱讀理解ASpeed walking has now become part of my daily routine for six years.I am always keen to do it regularly without a break.Even though I am neither a physician nor a specialist in medical science, I am fully aware that exercise, especially speed walking, helps maintain health and lowers the chance of falling ill.I urge everybody to speed walk on a daily basis, with one day off a week, or at least to do it three times a week.I managed to burn around 17 kg of fat after taking up speed walking.This should also be accompanied with a change in diet.We need to reduce how much we eat and avoid junk food, sweets and carbonate drinks.Reducing the amount of food we eat in the evening by around 80 percent and increasing how much water we drink are also good practice.Overeating should also be avoided.I usually walk at a speed of 1 km per 8.5 minutes.It will initially make you tired.However, over time it will become a habit and an addiction.This type of exercise will help you mentally, will also help you sleep and give you an appetite.It will make you physically fit and help burn fat.Speed walking makes you healthy and everyone can find time to walk.The problem is that some people do not plan their days and do not, therefore, find time.We can gain health and social benefits from speed walking.It will help change our lifestyles, fight diabetes, obesity and other illnesses.Arguments such as “I am too old and obese to walk” do not hold_water.People of any age who speed walk will see the benefits within a couple of months.Walking outdoors is ideal and it is best done in the company of friends.語篇解讀：本文是說明文。每天堅持快走被越來越多的人作為日常鍛煉的一種方法?？熳卟粌H可以減去身上多余的脂肪、走出好的身材，還可以預(yù)防疾病、走出健康。1What can be the best title for the passage?ABenefits of speed walkingBMy success in reducing weightCThe history of speed walkingDTips on how to keep healthy解析：選A標(biāo)題歸納題。作者在文中介紹了快走的益處，并且通過自身的實例進(jìn)行說明，故選A。2It can be inferred from the fourth paragraph that _.Aspeed walking possibly leads to an eating disorderBmany people are too busy to have a fast walk every dayCmore calories and fat will result in serious illnessesDspeed walking can effectively cure kinds of diseases解析：選C推理判斷題。依據(jù)第四段的第二句可知，快走有助于燃燒脂肪；依據(jù)尾句可知，快走會幫助改變我們的生活方式，有助于抵抗糖尿病、肥胖和其他疾病。由此可推知，過多的熱量和脂肪會導(dǎo)致疾病發(fā)生。3What does the underlined part “hold water” mean?AHave a drink.BMake sense.CWork out. DBuild up.解析：選B詞義猜測題。依據(jù)下文可知，不管多大年齡的人，在快走幾個月后就會看到快走的益處。因此此處指那些人說自己太老太胖而不能快走是沒有意義的。BMost of us are familiar with the “Silk Road”， a network of land trading routes which connected northwestern China to Europe since the Han dynasty.With its recent popularity, you may have heard of the “Tea Horse Road” as well, another network of land trading routes that also connected China to various parts of Asia and Europe before sailing became common.Historically, the “Tea Horse Road” is no less important than the “Silk Road”， and because of their different locations, the “Tea Horse Road” is sometimes referred to as “the Southern Silk Road”The “Tea Horse Road” has got its name as Chinese tea and horses were the main products traded along the route (together with medicine, salt, cloth and skins)Historians have traced the origins of the “Tea Horse Road” back to the Tang dynasty, when tea was being transported out of Yunnan to Beijing, Tibet, and other Southeast Asian countries.The “Tea Horse Road” was further developed during the Song and Ming dynasty, and remained a key trading route for Puer tea and other goods until the Qing dynasty.Like the “Silk Road”， the “Tea Horse Road” was not a “road” by itself, but a network of routes spreading out of Yunnans Puer County.In its more than 1,200 years of history, the “Tea Horse Road” served not only as a trading route, but also a bridge connecting different races (種族) politically, economically and culturally.Today, the “Tea Horse Road” is a hot spot for tourists.History aside, the “Tea Horse Road” is located near “The Third Pole of the Earth” and “The Roof of the Earth”， making it a spot of many attractions.語篇解讀：本文是說明文。茶馬古道是指存在于中國西南地區(qū)的民間國際商貿(mào)通道，是中國西南民族經(jīng)濟文化交流的走廊，也是早期溝通中國西南地區(qū)和亞歐商貿(mào)的重要通道。4What do we know about the “Tea Horse Road”？AIt dates back to the Tang dynasty.BIt was built earlier than the “Silk Road”CIt was built for trading in Southern China.DIt enjoyed greater popularity than the “Silk Road”解析：選A細(xì)節(jié)理解題。由第二段“Historians have traced the origins of the Tea Horse Road back to the Tang dynasty .”可知，茶馬古道是從唐朝時開始的。5Where is the starting point of the “Tea Horse Road”？ATibet. BBeijing.CPuer County. DEurope.解析：選C細(xì)節(jié)理解題。由第三段“.but a network of routes spreading out of Yunnans Puer County.”可知，茶馬古道的起點是中國云南的普洱縣。6The “Tea Horse Road” is now most popular with _.Abusinessmen BexplorersChistorians Dtourists解析：選D細(xì)節(jié)理解題。由最后一段“Today, the Tea Horse Road is a hot spot for tourists.”可知，茶馬古道現(xiàn)在是深受旅游者青睞的景點。CIf you need one more reason to be thankful, here it is.One recent study from the University of California San Diegos School of Medicine found that people who were more grateful actually had better heart health.“They showed better wellbeing, a less depressed mood, less tiredness and they slept better，” said the studys author, Paul JMills.Researchers at the universities of Utah and Kentucky observed that stressedout law students who characterized themselves as optimistic actually had more diseasefighting cells (細(xì)胞) in their bodies.Robert Emmons, a professor at UC Davis, said theres even more evidence.People who keep a gratitude journal have a reduced fat intake as much as 25 percent lower.Stress hormones (激素) like cortisol are 23 percent lower in grateful people.And having a daily gratitude practice could actually reduce the effects of aging to the brain.“Being thankful has such a big effect because of the feelings that go along with it，”Emmons said.“Gratitude works because it recruits other positive emotions (情緒) that have direct physical benefits.”Research shows that when we think about what we appreciate, the calming part of the nervous system works and that can have protective benefits on the body.“Some people may not be grateful by nature but it is a habit you can get used to，”said Dr.Norman Rosenthal, a doctor and author of Winter Blues.“One very good way is being aware of comparing up.It almost always leads to unhappiness because you can always find a person who is more advantaged than you are.”Norman says all you have to do is think about being grateful.“Some people say they dont have anything to be grateful for，”Norman said.“If you take such a person to find one little thing to be grateful for and focus on that, you find over time that the feeling of gratitude can change the way they see their lives.”語篇解讀：本文是說明文。研究表明感激不但使我們有好的人際關(guān)系，而且對我們的健康大有好處。7How does the author mainly explain the reason to be thankful?ABy presenting research findings.BBy making comparisons.CBy analyzing causes.DBy giving examples.解析：選A推理判斷題。第二、三、四段列舉了各個實驗、證據(jù)解釋了我們?yōu)槭裁匆屑ぁ?Why does the author mention law students in Paragraph 3?ATo advise us to be optimistic.BTo show that they are under great stress.CTo find a way to increase diseasefighting cells.DTo prove that gratitude is good for peoples health.解析：選D推理判斷題。第三段以對法學(xué)學(xué)生的實驗結(jié)果為證，證明了感激對身體健康有益。9Which of the following can replace the underlined word “recruits” in Paragraph 5?ABeats. BCollects.CPrevents. DChanges.解析：選B詞義猜測題。由畫線詞之前的“Being thankful has such a big effect because of the feelings that go along with it”可知，感激起作用是因為它調(diào)集了其他積極的情感。recruit此處意為“調(diào)集、獲取”。10What does Norman say about gratitude?AIt encourages comparing up.BIt makes one much younger.CIt is a skill that can be learned.DIt is up to ones attitude to their lives.解析：選C推理判斷題。由倒數(shù)第二段“.but it is a habit you can get used to .”和最后一段“Norman says all you have to do is think about being grateful.”可知，Norman認(rèn)為感激是種能夠被習(xí)得的技能。.閱讀七選五Audrey Hepburn was born in Belgium in 1929.She liked to spend time with her father.Perhaps he was not a warm father, but he was joyous and joked a lot.He had his horses, spoke 13 languages, and would take her gliding (滑翔)_1_ When she was six, Audreys father walked out.It was the first major blow in her life.From then on, Audreys childhood was unsettled.Her mother decided that it might be a good idea for her to learn English, so she sent her to a boarding school._2_ She felt like an outsider, but she learned English.Very soon the war broke out.Audreys mother sent for Audrey to join her in Holland.They were taken in by Audreys wealthy grandfather.Within a year, the Nazis turned against the Dutch.Then there was no heating, no school and no food._3_ She showed remarkable resilience (迅速恢復(fù)的能力) during the war.Audrey made her performance debut (初次表演) by dancing in wartime Holland.She didnt know how long the war was going to last, so she went to ballet (芭蕾舞) school and learned to dance._4_ After the war ended, Audrey carried on with her ballet training.In 1951, a famous French writer was looking for a leading lady for her bestloved novel._5
