课时跟踪检测(十一) Warm-up & Lesson 1 — Pre-reading 阅读理解AOnce upon a time, when you first attended a youth sporting event, your parents probably weren't expecting you to become a professional athlete.They signed up for a basketball, football or swimming course for you in the hope that you might learn lessons about winning gentlemanly, losing with dignity (尊严) and insisting on it when things get hard.Yes, playing games is good exercise, but it is the life lessons that matter most.For many of us, instead of looking to improve our minds and spirits, we began judging progress only by the size of our muscles or the numbers on a weighing machine.The thought that athletic competition is about greater life lessons and the building of character has been further undermined (削弱) by headlines about professional athletes.“And yet there's still strong evidence that sports strongly improve certain personal qualities，〞 says Angela Lumpkin, Professor of the Department of Health, Sport and Exercise Sciences at the University of Kansas.And that's true for athletes of any age.Amateur sports (业余体育运动) provide a safe place for competition.They also provide a practice ground for managing stress.The advantages of taking part in a sport can seep (渗透) into your professional life, too.In basketball, for example, “Getting everyone to play the right role on the court is the key to success，〞 says Alan Arlt, the founder of the Life Time Fitness basketball program Ultimate Hoops.“That is certainly useful in the business world, where everyone understands their role in the organization.〞“In athletic events, you go through good and bad times often in the period of two hours，〞 says former NBA head coach Flip Saunders.“Do you have the calm manner to settle yourself down, or do you totally lose it and get thrown out of the game which hurts both you and your team? All of that on­court experience has a real effect on how you deal with real­life situations.〞语篇解读：参加体育运动不仅是为了强身健体，更重要的是为了提高人的智商和情商。

AHave you ever felt so tired after staying up for a night that even coffee doesn’t give you the energy that you need？ You may have an energy drink, but the benefits of drinking one are heavily outweighed by the risks。

In the past years, more and more studies have found the deadly effects of energy drinks on your bodies. The sugar, caffeine and energy supplements(添加物） in energy drinks make up a deadly mixture of ingredients that can affect your heart function and send you to the hospital!A study by the University of Bonn， Germany found that frequent consumption of energy drinks can greatly change the way your heart functions。

The study went on to say that consuming energy drinks often causes significantly increased heart contractions(收缩） in adults， which has the potential of putting you at risk of irregular heartbeats.It is possible that many people are unaware of the alarming side effects of energy drinks because of the way they are labelled。

Opinions are divided.Some believe that human cloning is a good thing. Firstly, They think if people had too much work to do , they could get their own clone to help them. That wouldn’t be cheating because it would still be themselves doing the work. As a result, they would have so much time to rest and have fun. What’s more, human cloning could also solve the problem of finding the organs for organ transplants. So that it could help people lead longer and healthier lives.However, others are against it .They think human cloning is a terrible idea, which could cause a lot of problems. First of all, it could cause family confusion. If people were cloned , how could their clone fit into their family? Remember, their clone would be exactly like them. In addition, clone could cause problem for society. If everyone decided to be cloned there would be a population of explosion.In my opinion, I ’d prefer to have human cloning . In that case, we can clone people with special talents that would be helpful for social development.People are against the human cloning and the argument Paragraph 1Writer’s opinion about the topic Paragraph 2People are for the human cloning and the argument Paragraph 3Introduction of the topic Paragraph 4Task 2：Read the passage to fill in the formpara1Para2-3Para4Task 3：find out topic sentences in each paragraph.Paragraph 1 Topic sentence________________________________________________________________1)______________________________________________________________2) _____________________________________________________________3)___________________________________________________________________ whether we choose to be treated by Chinese traditional Medicine _____________________.（人们关于是否选择使用中药治疗的看法不同）。

In the 1330's, in urban areas all over Europe, Asia, Africa and the Middle East, up to one half of the population was lost to the Black Death.Another epidemic that spread in similar conditions was the Great Flu Epidemic of 1918, also called the Spanish Flu.It struck near the end of the First World War and left families 6.mourning (mourn) worldwide.The SARS epidemic began in 2002 with a lung disease in Guangdong Province and spread 7.quickly (quick) after Dr Liu Jianjun, the 8.carrier (carry), came to Hong Kong and passed the virus to people who carried it to Canada, Vietnam and Singapore.No one really knew much about SARS as it was completely new.

We can take you home in all cases.7．Train services returned to normal again after the strike.8．I fell into comas when the stone hit me on the head.Ⅲ.阅读理解ASport is not only physically challenging, but it can also be mentally challenging. Criticism from coaches, parents, and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents' and coaches' criticisms to heart and find fault with themselves.Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today's youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find fault with youngsters' performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates (激发) and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.语篇解读：教练和家长对于年轻运动员表现的评价是很重要的，应当给出正面鼓励，而非一味指责。
