四、阅读 (共两节)

第一节 阅读理解(共 20 小题;每小题 2 分,满分 40 分)

( A )

Go to church, then have a big lunch, then go out to play while mum does the housework. That was a typical(典型的) British Sunday in the 1960s. But things now could not be more different.

Some British sociologists recently studied the typical British Sunday. They found that people get up later and do less housework than they did 40 years ago. They are far more likely to be out shopping or enjoying themselves than cooking Sunday lunch.

Sunday mornings were busy 40 years ago. Most women caught up on their weekly housework and cooked a nice lunch. They seldom allowed themselves any “leisure” until afternoon, after the dishes were cleaned. Then there would be another rush to the table between 5: 00 pm and 6: 00 pm for tea.

But now, Britons can have brunch( 早午餐) at the restaurant. Fewer people bother( 添麻烦) to cook themselves.

“You only have two free days a week. You don’t want to have to waste one because there is nothing

to do but watch boring TV” said Elizabeth Biggs, 25, a producer in London.

“On Saturday you are recovering from the week,” Biggs added. “Sundays are the last chance for the weekend — you want to get as much as you can out of the day before you have to go back to work.”

In the past, British women usually did their shopping during the week, while the husband was at work. “Now men seem to do that as much as women,” said Jonathan Gershuny, a professor who took part in the study.

Men also do more housework now on Sundays. Back in the 1960s, men were far more likely to spend Sundays out of the house — at the pub or playing football — before lunch.【广州卓越教育】

On an elementary school playground, hundreds of children run and jump, smiling and laughing as they play. Watching sea otters(海獭) playing in their own environment is like watching children at play. Sea otters, which are presently on the endangered species list, are experiencing an increase in population.

【广州卓越教育】

Groups of sea otters live on the shores of the North Pacific Ocean. They are seldom found far from land but almost spend their entire lives at sea. The otter has been known to dive as deep as 180 feet and stay underwater as long as minutes. Each day the sea otter eats as much as one-fifth of its body weight in fish or shellfish.

Not only are sea otters playful, they are also amazingly resourceful. Their favorite food, abalone (鲍鱼) , is protected by a thick shell that sea otters are unable to break with their teeth. Sea otters use stones from the ocean floor and break the abalone open on their bellies (肚子)as they move slowly across the surface of the water on their backs, a behavior that makes them one of only a few animals on Earth, including human beings, to use tools! Their intelligence is also displayed while sleeping. In order not to move into dangerous waters, sea otters actually cover themselves with plants on the sea, which keep them in place before falling asleep.

Because sea otters have a special means of keeping insulated(隔热的) , they can keep their body heat in their cold environment. They have unbelievably fine fur (毛)that traps tiny bubbles, and that keeps them comfortable when warmed by body heat. However, their fur loses this insulating quality if it becomes dirty.

Sea otters have faced dangers from hunters in the past and from oil spills more recently. Fortunately, due to a 1911 agreement and to rescue and habitat protection efforts, the sea otter population has nearly recovered.

( ) 34.What can be inferred about sea otters’ fur?

A.It consists of tiny air bubbles. B.It has a layer of insulating water bubbles.

C.It keeps sea otters warm only when it’s clean.

D.It becomes dirty easily in the cold environment.

( ) 35.We can learn from the passage that sea otters _______.

A.mostly stay on the land B.like sleeping among stones

C.are increasing in population D.usually hide themselves under plants in the sea

When we talk about instant (方便的)messaging tool, which will be the first one jump into your mind? If your answer is QQ or MSN, I must say you’re a bit old fashioned. Today, Wechat is becoming the most popular text and voice messaging tool all over the world. It has had 700 million registered (登记)users all over the world up to now. It has a Chinese name Weixin, it is necessary for the young people in China to have the communication tool. Actually, it is also a new product from Tencent(腾讯) , so we can call it QQ’s little brother.

You can log in to Wechat with your Facebook account(账号) or sign up with your phone number, and then add your friends’ number in your contact list, by which you can chat with your family of friends in a brand new way by using your phone no matter when and where you are. It’s just like using a walkie talkie( two way radio) . But you don’t need to worry about other things, such as basic fees. It won’t cost you extra money to make conversations.

You can also only need three steps to finish calling others through Wechat. It is free for ten minutes. If you want to make a phone call again, you need to pay for it through a credit card. Someone thinks the sound in the phone is not clear. There is some noise in it. It is not safe for the user. So you should pay attention to your personal information and not share it to others.

广州卓越教育 第三篇_卓越教育创始人唐俊京

卓越教育创始人唐俊京:从深大“首富”到课辅超人

他是广州课外辅导行业的“三剑客”之首,这个没有参加过高考的执信保送生,日后却从事着与高考息息相关的事业;他怀揣着父母给的400元生活费踏入大学的校门,四年后怀抱着30万现金毕业,成为当时深大的学生首富;他创办的食品公司一度成为某世界500强公司最强有力的竞争对手;经历破产风波后,走投无路的他办起了补习社,从此卓越教育一直延续至今,成为华南课外辅导的旗舰„„

内向的推销员

唐俊京与腾讯CEO马化腾同一届,但1993年他们毕业时,前者却是当时深圳大学的学生首富。大学四年,唐俊京干过推销、炒过股、进行过投资,在那个深圳遍地是黄金的年代,他掘到了自己的第一桶金——30万,成为他毕业后创业的启动资金。

唐俊京小时候有过与大多数同龄人一样的理想——当科学家。由于从小体弱多病,在高三毕业填报志愿时,他与胞弟唐俊膺跟父母产生了意见分歧,父母希望他们能学医,但兄弟俩对医学都不感兴趣,而是选择了经济类专业,最后唐俊京被保送进深圳大学国际金融专业,弟弟则被保送进中山大学国际贸易专业。 进大学后,为了减轻家里的经济压力,兄弟俩萌生了兼职赚生活费的想法。“刚进大学,我就去推销磁吸电话本。”唐俊京说。对于天生内向的他来说,做推销员需要克服性格上的不足,“记得第一次去银行推销电话本的时候,那家银行的行长在二楼办公,一楼有保安,我当时在门外驻足了很久,趁保安不注意偷偷溜进去。到了行长办公室门口也不敢敲门,在走廊里来回踱了10多分钟,才鼓起勇气敲开了行长办公室的门。”唐俊京回忆,他的陌生拜访终于得到了机会——一位行长被他打动,订了一些电话本作为礼物赠送给客户。从此,唐俊京就开动脑筋,陆续又推销挂历、台历和钥匙扣给银行,都大获成功。“那时我和弟弟跑到珠三角各处去寻找货源,然后运到深圳去卖。我们推销的网点从深圳扩展至整个珠三角地区。”

上世纪90年代初,股票刚刚兴起,他们就把推销赚来的钱投到股市。谈起1992年全国发行新股时全国人民疯涌到深圳的壮观场面,唐俊京乐呵呵地说:“当时为了购买新股,全班同学在证券交易部门前排了几天几夜的队,但最后只有一个同学买到了,那个同学出来时发现自己的皮带都被挤没了。”由于兄弟俩及时把资金从股市中抽离出来投资运输车队,逃过了1993年股市大跌这一劫。 “我上大学时怀揣爸妈给的400元钱到深圳,毕业后用一个大麻袋装着30万现金回广州。当时和一个同学一起去银行取钱,然后搭火车,回到广州,麻袋的带子都提断了。”提起往事,唐俊京很庆幸自己的大学四年没有蹉跎。 走投无路开办补习社

俗话说:“没参加过高考的人生是不完整的。”不知是不是命运给这对孪生兄弟开了个玩笑,当年他们都“逃”过了高考,但如今,他们却从事着与高考息息相关的事业,每年都有大批高三学生为了高考而参加卓越教育的补习班。也许命运就是这样,人总是要平衡的,你缺什么就补什么。

1993年,唐俊京大学毕业,当时他手握好几个金融行业的Of-fer,“但一份稳定的工作让我看到自己60岁退休时是什么样子,由于心有不甘,所以想先自己出来闯一闯,去看看外面的世界。”唐俊京说。

就这样,一对没有参加过高考的孪生兄弟和一个出身教育世家的中大毕业生走到了一起,“三剑侠”组合的并肩作战从大学毕业时开始,并一直延续至今。

起初,他们用大学时赚的第一桶金在广州开了一家广告公司。后来他们发现百事公司推出的一款带有“奇多圈”小玩具的膨化食品风靡全国,便模仿奇多,到武汉创办了一个“山寨”企业——奥多食品有限公司。

“食品是其次,玩具才是主角。”凭借他们积累起来的营销经验,这款带有“奥多圈”的零食在全国迅速铺开,一度成为百事最强的竞争对手。唐俊京说:“刚开始我们很是风光,第一年营业额就达1400多万,在全国20多个城市设有分公司和办事处,员工近三百人。”然而好景不长,当玩具已不再流行时,产品的销量急剧下降,亏损、负债也随之而来。“我们欠了一屁股债,狼狈地‘逃’回了广州。”

1997年折戟返穗,身无分文的“三剑客”为了生存,开始寻找再创业的路子。“现在有很多人都说我们太有战略眼光了,十几年前就看到了教育产业的发展前景,其实说实话,我们选择做教育是因为走投无路。”当时投资任何行业都需要资金,而开办补习班不需要前期投入。“我跟小学的校长谈好了,场地费上完课再结算,老师的工资也是上完课再付,就这样‘空手套白狼’,把租金、场地、师资谈妥后,正式招生开课。”

为减少家长担心辅导机构卷款逃跑之忧,他们起初定价很低,单科补习一个月才几十元,这也吸引了不少学生家长。“我们第一期是‘期末冲刺班’,来了近200个学生。”唐俊京回忆道。当时,市场上的补习班大多是家庭作坊式的,已经有企业运营经验的唐俊京对补习社进行企业化运作。在唐俊京看来,这也是卓越教育能在创立短短一年后成为广州培训市场领军机构的原因所在。

“以前都是老师评价学生,但我们反其道而行,让学生评价老师。”每次老师上完课后,卓越便会马上对学生进行调查问卷,了解老师的优缺点,通过这种方式筛选老师。另外,上完一期课程,就马上召开家长会,“家长当时很感动,第二期招生就暴涨到800人。”

尽管刚开始顺风顺水,但中途遇到了几次不小的波折,也差点让卓越教育关门。“第一次是国家号召教育‘减负’。那时候报纸天天大幅报道,教育局还点名批评我们,当时只能靠老学员维持。第二次是2003年卓越教育开办高四复读学校,当时的校长离职,带走了一大批优秀老师,几乎带来灭顶之灾。第三次是非典期间,停课一两个月,还退了一大部分学费给学员。幸亏同事们很团结,齐心协力渡过了难关。”

【广州卓越教育】

对话

课辅市场远没有饱和

《毕业生》:卓越教育在广州起家,您认为广州中小学课外辅导市场已趋于饱和了吗?卓越教育在广州本地还有没有扩张计划?

唐:我认为这个市场还远远没有饱和。广州课外辅导市场只开发了

30%—40%。在广州市场,再翻两三倍是完全有可能的,这只是时间的问题。根据市场需求,我们在广州每年都会建新校区。

《毕业生》:最近,您接受腾讯专访时说:“相对而言,网络教育和中小学课外辅导的前景会更好。”而近日,华附在线学习中心正式上线,您觉得网络课堂对课外辅导机构会构成威胁吗?

唐:我个人认为至少在近三五年网络课堂对我们的冲击不大。课外辅导是公办学校教育的有力补充。对于网络课堂,在国外,比如韩国,网络教育非常成功,但韩国高速网的使用率是90%以上,在中国远远没有达到这种程度。另外,能够在网络上学习的学生需要有非常强的自控和自主学习的能力。

《毕业生》:近来培训机构接二连三上市,卓越是否会加紧上市步伐? 唐:我们目前完全可以上市,但我们并不是为了上市而上市。对于一个企业的成长来说,我认为上市只是一个中途的加油站,我们可以通过上市获得一些资金、获得一些更规范的管理,使我们的企业今后能走得更好。

《毕业生》:业内有质疑的声音,认为你们在外地发展困难重重,势头远不如广州本地。对于这些质疑,您是如何看待的?

唐:在外地发展只有一种模式可以迅速复制,那就是“一对一”补习。但卓越主要的发展模式是班级制,这种模式是比较难复制的。对于卓越教育来说,外地市场会有一些难度,因为各地的教育政策与考试的方向都不一样,这是一个很大的挑战。但是目前在我们整体收入里,外地的收入已经达到15%,在同行业的比较中还是不错的。再者,教育行业靠口碑,这是个慢热的过程,我们现在面临的是从0到1的突破,这个过程很漫长,但从1到10的转变却是非常快的,这是靠口碑来传播的。

两个校长谈成功要素

不同的人对于成功有不同的定义,唐俊京所定义的成功是:在一个领域很有影响力,在这个领域可以找到自己的自由王国。

决定一个人成功的要素是什么?唐俊京说,他和华南师大附中校长吴颖民先生曾就此交流过,吴校长提到四点:“第一,要自知,看清楚自己的优势和劣势、强项和弱项;第二,了解外面的世界,也就是拓宽自己的视野,找到适合自己的领域;第三,要有百折不挠的精神;第四,善于学习,是终身学习者。”唐俊京认为,这些都是成功者必备的素质,但他认为,成功的要素还可以增加更丰富的元素,“比如要有合作精神,我认为今后这个社会不是一个人打天下的,而是一个团队打天下;另外,还要有吃苦耐劳的品质。你具备了这些素质,成功只是迟早的事情。”
