As the world’s greatest skateboarder, he talked about how his life was not always so miraculous (奇迹般的).He mentioned one day he was skating on top of the world, and the next day the sport of skateboarding fell right on its face. Life for Tony has had its ups and downs, and what brought him back up was the way he believed in himself. One of the most tragic events in Tony’s life was that his father passed away. Although he suffered such pain, he never lost sight of his dream. He put his energy into his dream, which helped him overcome his sadness. One part of Tony that completely impressed me is the way he accepts himself. His goal is never to do better than others, but to do his best. If he does the best he can, it doesn’t matter how anyone else takes him. That’s tr ue and wise. As for me, I play baseball and things aren’t going so well, but I am trying my hardest, that’s life. It is how you approach those bad days that will keep you on top. Confidence brought Tony to the next level. During our meeting he continually talked about the importance of following one’s dream. He also said, along with that, one needs to have a strong faith in one’s own ability to achieve that dream, no matter what challenges are presented. By the end, I didn’t see th e same guy who had walked through the door an hour earlier. Now I view him as more than a world-class skateboarder. He is also a normal person who has dealt with many of the same problems we all face, but the difference is, he is always able to rise above his problems by having faith in his dream.24.

The example of the author’s playing baseball is used to show he _______.A. accepts To ny Hawk’s suggestionB. doesn’t want to play baseball anymoreC. has the same view of life as Tony HawkD. wants to be as successful as Tony Hawk26.

His _______.A. achievementB. unusual experienceC. confidence in winning the gameD. determination to realize his dreamCPeople eat more when they are glued to the television, and the more entertaining the program is, the more they eat, according to a new research.It seems that distracted(分心的)brains do not notice what the mouth is doing, said Dr. Alan Hirsch, neurological director of the Smell and Taste Treatment and Research Foundation in Chicago.Hirsch explored the impact of smell, taste and eating behaviors while watching TV by measuring potato chip consumption. Forty-five volunteers ate as many chips as they wanted every six minutes while they watched monologues by late-night talk show hosts David Letterman and Jay Leno. They were still given chips to eat when the television was off. Hirsch found people ate an average of 44 percent more chips while watching Letterman and42 percent more while viewing Leno, than when they did not watch TV.If you concentrate on how the food tastes, you'll eat less because you'll feel full faster, "Hirsch said in an interview at the Endocrine Society's annual meeting in Toronto. So if that's the case, let's look at the opposite. What if you're distracted? If you're distracted, in theory, then you'd eat more."Through his research at the foundation, Hirsch has helped people overcome the loss of sense of smell and sense of taste. which typically results in weight gain because the brain does not know when it should stop eating.The ventromedial nucleus(腹内侧核)in the hypothalamus( 下丘脑), where the so-called satiety(饱腹感)center is located. tells the body whether it is hungry or full. It is inhibited or tricked, the result can be changes in eating patterns, he said.People who cook spaghetti all day don't feel like eating spaghetti at the end of the day, "said Hirsch," By being exposed to a smell all day long it's tricking the hypothalamus."Volunteers were asked to concentrate on the sensory characteristics of the food such as taste and smell. Researchers say these sensory clues, in addition to inner body changes. mark satiety.But when distracted. a person does not pay attention to either the body's sensations of feeling full, or to the sensory characteristics of the food.Many studies have linked being fat to watching television and that link is likely due to inactivity, Hirsch said. But perhaps entertaining shows are also contributing."If you want to lose weight, turn off the television or watch something boring," he said.27. When Hirsch conducted the research, he______A. evaluated the degree of the volunteers' loss of taste.B. measured the amount of the chips the volunteers ate.C. analyzed the volunteers' preference on TV programs.D. counted the minutes the volunteers spent on TV programs.28. According to the research, when will you feel full faster?.A. When we are distracted.B. When we focus on how the food tastes.C. When we are watching entertaining programs.D. When the brain doesn't know when it should stop eating.29. Why does the author mention "People who cooks paghetti all day don't feel like eating it at the end of the day"?A. It tells us that eating spaghetti is inhabited.B. It indicates that spaghetti doesn't taste good at the end of the day.C. It tells us that people who cook spaghetti don' like eating spaghetti.D. It shows that smell is "telling" the hypothalamus that the body is full.30. What is the main purpose of the article?A. To prove that being fat is linked to inactivity.B. To reveal the relationship between TV programs and eating behaviors.C. to explain why watching television makes people eat more and gain weight.D. To find how sensory characteristics of the food affects people's feelings of eating.DIn the picture Landscape with Diogenes by the 17th century French artist Poussin, the ancient philosopher Diogenes is described casting away his last possession, a drinking bowl. He realizes he doesn’t need it after seeing a youth cupping a hand to drink from a river. The significance for us is that Diogenes’ spiritual descendants (后代)known as “new minimalists” are now everywhere, if not as completely possession-free as he was.There are hundreds of websites praising the virtues of tidy living. Everyone is trying to cut down on things these days. People are trying to reduce their carbon footprints, their waistlines, and their monthly outgoings. What’s more, there’s a general fear that people are becoming choked by their possessions, and this is fueled by the knowledge that the leading hobby these days seems to be shopping. It’s true, sal es of e-readers and e-books go beyond those of paperbacks. As a result, the need for bookshelves is cut out.However, today’s new minimalists don’t urge us to burn our books and destroy our CDs, but just make sure we have them as digital files. So, for example, I have digitised versions of some of my old vinyl LP (黑胶) records and haven’t, as yet, stimulated myself to take the LPs to the nearest charity shop – and I admit I shall probably go on keeping them. Technology has gone beyond our dreams and there is always the doubt that our hard drives will crash and all will be lost. Far more important, however, is the fact that our memories are so inseparably tied to our possessions that we can’t get rid of stuff. We are not exactly suffering withdrawal symptoms (症状) as we try to break our addiction to objects. We are just acquiring new stuff, which means we can bin or recycle our old stuff.I’m happy to have found another website which seems to solve a whole lot of problems at once – a thriving online advice service offering storage solutions. The interior (室内的) designer responsible for this does not suggest getting rid of stuff, but rather recommends buying more stuff such as elegant flexible baskets or colourful lidded containers to hide the first lot of stuff from view. I love this philosophy –convince yourself you’ve got your desire for possessions under control, without having to lose a thing. After all, we aren’t merciless enough to follow Diogenes and cast away all our possessions.31. Why does the author mention a picture by the artist Poussin?A. It illustrates a modern trend.B. It describes a wise philosopher.C. Its meaning is only now becoming clear.D. Its message is not as simple as it appears.32. The author believes minimalism may not succeed mainly because of people’s ______.A. resistance to media pressureB. laziness in the face of changeC. lack of faith in digital hardwareD. strong bond with physical objects33. According to the author, people invest in smart new storage in order to_____.A. satisfy their desire to make purchasesB. make attractive additions to their homesC provide a temporary solution to a problemD. ease their conscience over having too many things.34. Which of the following would be the best title for the passage?A. Less is MoreB. Low Carbon Is an AttitudeC. Treasure What You HaveD. Psychology of Overconsumption.Section B: Choose the best choice that can be filled in each blank from the seven choices after the passage. One of the choices is redundant (多余的).The Value of TearsTears can ruin make-up, bring conversation to a stop, and give you a runny nose. Tears leave you embarrassed and without energy. Still, crying is a fact of life, and your tears are very useful. Even when you’re not cryin g, they make a film over the eye’s surface.___35___When tears fall, they reduce stress. But we tend to fight them for all sorts of reasons. “People worry about showing their emotions, afraid that once they lose control they’ll never get it back.”___36___ After we cry, the feelings that caused the tears often disappear.Sometimes people become much stressed and can’t cry. Whatever emotion they are feeling—shock, anger, fear, or sadness—is being held back.But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry. ___37___Patients practice crying just to become used to expressing emotions. She suggests safe, private places to cry, like under the bedcovers or in the car. Crying is a way of reducing tension, but people don’t like it when others cry because it makes them tense.___38___ And they’ll do just about anything tomake you stop.In certain situations, such as at work, tears are not appropriate. It’s good not to cry during a tense business discussion.___39___You should also act out the whole situation again and be as noisy and angry as you like. It will help you feel better. “And,” she adds, “Once your tears have taken away the stress, you can begin to think calmly of ways to deal with the problem.”Tears are a sign of our ability to feel. If you find yourself near someone crying, deal with it. And never be afraid to cry yourself.A. They too may be holding back a need to cry.B. They cry for different reasons.C. She gives crying exercises.D It contains a chemical against infection.E. The fact is that no emotion lasts forever.F. It forms in response to the stress on the surface of the eye.G. But once you’re safely behind closed doors don’t just cry.Part IV. Grammar (1’×10)A语法填空Rose wanted a job. She went to many offices but she didn’t like any of them.

塑料,是工业文明的结果,它给人类带来便捷的同时也带来了无穷的麻烦和灾难。
目前,市面上的塑料保鲜膜都不能降解,如果把它们埋在土壤中,塑料中的塑化剂会渗透到土壤和水里,最终会随着水和植物进入人体内,同时塑料分子也会进入人体,对人体造成危害。
如今,小小的海藻摇身一变,就可以成为新型环保保鲜膜,这为解决塑料污染提供了一种新的可能。
海藻种类繁多,共有两万多种,几乎所有海洋植物都可归入藻类。
海藻拥有巨大的开发潜力,可开发成药品功能性食品、化妆品。
现在,小小的海藻还能制备成保鲜膜。
科学家们发现,海藻富含多种多糖类物质,如褐藻胶、琼胶、卡拉胶等,这些多糖类物质形成凝胶后可以延展成薄膜,较好的柔韧性使其拥有制作保鲜膜的潜质。
常规的塑料保鲜膜在使用一次之后就会被丢弃,而海藻保鲜膜可以和包裹的食品一起进行烹饪或直接食用。
此外,一个普通的塑料袋,完全降解需要200~1000年,而海藻保鲜膜如果被人们不慎丢进自然界,只要和足够的水接触超过2小时,就会分解为有机物,进入土壤中和大自然融为一体。

三、现代文本阅读
《获得教养的途径》节选
世界文学的辉煌殿堂对每一位有志者都敞开着,谁也不必对它收藏之丰富望洋兴叹,因为问题不在于数量。
有的人一生中只读过十来本书,却仍然不失为真正的读书人。
还有人见书便生吞下去,对什么都能说上几句,然而一切努力全都白费。
因为教养得有一个可教养的客体作前提,那就是个性或人格。
没有这个前提,教养在一定意义上便落了空,纵然能积累某些知识,却不会产生爱和生命。
没有爱的阅读,没有敬重的知识,没有心的教养,是戕害性灵的最严重的罪过之一。
当今之世,对书籍已经有些轻视了。
为数甚多的年轻人,似乎觉得舍弃愉快的生活而埋头读书,是既可笑又不值得的;他们认为人生太短促、太宝贵,却又挤得出时间一星期去泡六次咖啡馆,在舞池中消磨许多时光。
是啊,"现实世界"的大学、工场、交易所和游乐地不管多么生气蓬勃,可整天呆在这些地方,难道就比我们一天留一两个小时去读古代哲人和诗人的作品,更能接近真正的生活么?不错,读得太多可能有害,书籍可能成为生活的竞争对手。
但尽管如此,我仍然不反对任何人倾心于书。
让我们每个人都从自己能够理解和喜爱的作品开始阅读吧!但单靠报纸和偶然得到的流行文学,是学不会真正意义上的阅读的,而必须读杰作。
杰作常常不像时髦读物那么适口,那么富于刺激性。
杰作需要我们认真对待,需要我们在读的时候花力气、下功夫......
1.作者说"有的人一生中只读过十来本书,却仍然不失为真正的读书人",那么,你认为怎样的人才是"真正的读书人"?
2.作者写道:"因为教养得有一个可教养的客体作前提,那就是个性或人格"。
为什么通过读书获得教养要和"个性""人格"联系在一起?
3.你怎样理解"不错,读得太多可能有害,书籍可能成为生活的竞争对手"这句话?
《想北平》节选
②可是,我真爱北平。
这个爱几乎是想说而说不出的。
我爱我的母亲,怎样爱?我说不出。
在我想做一件事讨她老人家喜欢的时候,我独自微微地笑着;在我想到她的健康而不放心的时候,我欲落泪。
言语是不够表现我的心情的,只有独自微笑或落泪才足以把内心表达出来。
我爱北平也近乎这个。
夸奖这个古城的某一点是容易的,可是那就把北平看得太小了。
我所爱的北平不是枝枝节节的一些什么,而是整个儿与我的心灵相粘合的一段历史,一大块地方,多少风景名胜,从雨后什刹海的蜻蜓一直到我梦里的玉泉山的塔影,都积凑到一块,每一细小的事件中有个我,我的每一思念中有个北平,这只有说不出而已。
③真愿成为诗人,把一切好听好看的字都浸在自己的心血里,像杜鹃似的啼出北平的俊伟。
但我不是诗人,我将永远道不出我的爱,一种像由音乐与图画所引起的爱。
这不但是辜负了北平,也对不住我自己,因为我最初的知识与印象都得自北平,它在我的血里,我的性格与脾气里有许多地方是这个古城所赐给的。
我不能爱上海与天津,因为我心中有个北平。
可是我说不出来!
④伦敦、巴黎、罗马与堪司坦丁堡,曾被称为欧洲的四大“历史的都城”。
我知道一些伦敦的情形,巴黎与罗马只是到过而已,堪司坦丁堡根本没有去过。
就伦敦、巴黎、罗马来说,巴黎更近似北平,不过,假使让我“家住巴黎”,我一定会和没有家一样地感到寂苦。
巴黎,据我看,还太热闹。
虽然那里也有空旷静寂的地方,可是又未免太旷,不像北平那样既复杂而又有个边际,使我能摸着——那长着红酸枣的老城墙!面向着积水潭,背后是城墙,坐在石上看水中的小蝌蚪
或苇叶上的嫩蜻蜓,我可以快乐地坐一天,心中完全安适,无所求也无可怕,像小儿安睡在摇篮里。
是的,北平也有热闹的地方,但是它和太极拳相似,动中有静。
巴黎有许多地方使人疲乏,所以咖啡与酒是必要的,以便刺激;在北平,有温和的香片茶就够了。
⑤虽说巴黎的布置比伦敦罗马匀调得多,可是比起北平来还差点儿。
北平在人为之中显出自然,既不挤得慌,又不太僻静,连最小的胡同里的房子也有院子与树,最空旷的地方也离买卖街与住宅区不远。
北平的好处不在处处设备得完全,而在它处处有空儿,可以使人自由地喘气;不在有许多美丽的建筑,而在建筑的四围都有空闲的地方,使它们成为美景。
每一个城楼,每一个牌楼,都可以从老远就看见。
况且在街上还可以看见北山与西山呢!
⑥好学的、爱古物的人们自然喜欢北平,因为这里书多古物多。
我不好学,也没钱买古物,但我却喜爱北平的花多菜多果子多。
花草是种费钱的玩艺,可是北平的“草花儿”很便宜,而且家家有院子,可以花不多的钱而种一院子花。
墙上的牵牛,墙根的靠山竹与草茉莉,省钱省事而且会招来翩翩的蝴蝶。
至于青菜、白菜、扁豆、毛豆角、黄瓜、菠菜等等,大多数是直接由城外担来送到家门口的。
雨后,韭菜叶上还往往带着雨时溅起的泥点。
青菜摊子上的红红绿绿几乎有诗一般的美丽。
果子有不少是从西山与北山来的,西山的沙果、海棠,北山的黑枣、柿子,进了城还带着一层白霜儿,美国包着纸的橘子遇到北平带霜儿的玉李,还不愧杀!
⑦是的,北平是个都城,而能有好多自己产生的花、菜、水果,这就使人更接近了自然。
从它里面说,没有像伦敦的那些成天冒烟的工厂;从外面说,它紧连着园林、菜圃与农村。
采菊东篱下,在这里,确是可以悠然见南山的。
像我这样的一个贫寒的人,或许只有在北平才能享受一点清福吧。
⑧好,不再说了吧,要落泪了。
真想念北平呀!
注:文中说的“北平”是1928~1949年间对北京的旧称。
1、本文第②段中作者说“我爱北平也近乎这个”,“这个”指的是什么?
2.第②段中,作者说“每一细小的事件中有个我,我的每一思念中有个北平”,这句话的含意是什么?
3.第④~⑦段中,作者笔下的北平具有多方面的特点,请写出其中的主要特点(每处不超过10个字。
) 在表现北平的特点时,作者为什么要用文字描写国外的城市?
4.文章以“要落泪了。
真想念北平呀”收笔,这一笔好在哪里?。
