阅读理解

(A)

Do you blank out, freeze up or feel so nervous in exams that you have trouble writing answers to questions that you knew just the night before? If so, you likely have a case of test anxiety. But, don’t panic. By recognizing the problem, you are taking the first step towards overcoming it.

Believe it or not, a touch of nervousness can sharpen your mind, allowing you to perform more quickly. This is because under stress, the body gives off the hormone adrenaline (肾上腺素), which prepares it for something important that will happen. However, too much anxiety can result in sleeplessness, loss of appetite before tests, and poor performance. Some people might feel shaky, hot or even sick.

If you worry a lot or are a perfectionist, you are more likely to have trouble with test anxiety. Those who have prepared poorly for a test or have had negative experiences taking tests may also experience test anxiety.

When you feel a storm of anxiety coming on, stop what you’re doing and make you r mind a blank. If possible, actually tell yourself to “STOP!”.This will get your mind off the stress. Then think of being at a place of comfort and let your body relax. As you continue the test, find questions you know the answers to and answer them first. This will help restore your confidence. Talk to yourself using positive language. Make it a habit to replace each negative thought with a logical reason. For example: “I’ve studied hard and I know the material, so I’m ready to do the best I can.” Another thing you can do is to learn to accept mistakes. In fact, they can be valuable learning opportunities.

Last but not least, start test preparation early—three to five days ahead of the quiz or test. After all, good study habits and skills—for example, time management and note-taking—will give you the feeling that you are in control.

65. According to the text, people who ______ are more likely to have trouble with test anxiety.

C. some stude nts can’t sleep well before the test

You must have seen an oil lamp before. But do you know how it works?

One end of the lamp wick(灯芯) is immersed(把……浸入……之中) in oil and the other end is not immersed. When you light the end which is not immersed, it will burst into flame. This is because the oil is able to rise up the lamp wick thus helping it to burn.

In the same way, if you immerse the end of a piece of chalk into a glass of water, the water will soon climb up the chalk making it wet.

If a piece of ordinary glass tubing is heated in a gas flame until it becomes soft,it can be pull into a tube of a very small hole. Immerse the tube into water or any other liquid which wets glass, you will find that the liquid rises to a height of several centimeters. This is known as capillary action. The liquid rises because there is an attractive force between the liquid and the glass. The attractive force depends on the diameter of the tube and the type of liquid used.

70. Why can an oil lamp work?

A. Because there is oil.

B. Because there is oil climbing up the wick.

C. Because the other end is immersed.

D. Because the wet end is lighted.

71. The passage mentions all the things except _______ .

72. The last sentence means that _______ .

A. the thinner the diameter, the greater the attractive force

C. the thinner the diameter, the smaller the attractive force

D. oil climbs up higher than water

73. The liquid rises up a tube because _______ .

A. the tube is thin

B. the glass has an attractive force

C. the liquid tends to rise up

Michael Phelps 23, used to hate his body. Now it is admired by millions of people. As a kid, he was bullied(欺负)for having a lisp(口齿不清)and big ears. But now Michael Phelps’s name belongs to Olympic history.

Behind Phelps’s success lies a story of triumph (胜利)over challenges. Phelps and his sisters Hilary and Whitney were brought up by their teacher mother Debbie in Baltimore after she broke up with her husband. It was a working class childhood.

Phelps has spoken of the “deep hurt” he felt when laughed at over his “sticky-out ears” , lisp and long arms

He also struggled with Attention Deficit Hyperactivity Disorder(多动症) and was put on medication for two years. Debbie said:“When he was young, I was told, ‘Michael can’t sit still, Michael can’t be quiet’, Michael can’t focus’. I said,’ Maybe he is bored’. The teacher said, ‘He is not talented. Your son will never be able to focus on anything”

Swimming saved him. And has also made him what he is today —a 1.93m tall winning machine, with an unbelievable 2.01m reach. His coach Bob once said:“Michael is motivated by success, by fai lure, by money, by people saying things ”about him—anything that he turns into a reason to train harder,swim better.”Phelps spends enough time in the pool to earn the nickname of“flying fish”.He covers more than l00km in the water every week and trains six hours a day,including Christmas.

85.Translate the underlined phrase into Chinese.

86.What did Phelps suffer from in his childhood?

87.How far can he swim when he stretch his body?

89.What do you think of the most important reason for his success?

In early times Europeans did not know Australia was there. But they thought there must be land in the south of the world. So, about 500 years ago, on their maps of the world, they put it in a big southern continent. In those days they wrote in Latin instead of their own languages. The name they gave to this unknown continent was in Latin. It was Term Austmha. In English this is Unknown Southern Land. So when the British found this land, they called it Australia.

But the British were not the first Europeans to find Australia. Portuguese, Spanish and Dutch sailors all saw it earlier. That was at the beginning of the 17th century . The Dutchman Willem JansToon was actually the very first European to find the coast of north Australia. The Dutch had already named the islands Indonesia. They wanted the spices that grow there. In 1606, Janszoon sailed south to look for more spice islands. He did not find any, but he found Australia. There were no spices there, so he was not interested in it.

Other Dutch, Spanish and Portuguese sailors followed him. They sailed along the north and west coasts. They also did not think much of this new land. The Dutch called it New Holland, after their own country. The British and French followed the Dutch. The first British sailors to come to Australia also did not think much of it. That was in 1688.

So at first none of the Europeans were interested in this new discovery. But 70 years later the British Government became interested in it. They were afraid the French would take the new land. So they sent Captain James Cook in his small ship to get there first.

曲径通幽话语文----中学语文学法指导(演讲稿)-东北育才学校

曲径通幽话语文----中学语文学法指导 (演讲稿) 作者:姚翠来源:本站原创发布时间:2006-05-23 点击数:3254 今天,我既是作为语文教师,也是一位初中生的家长,从我个人的经历和感受来和各位家长聊一聊孩子们在语文学习方面的问题,着重于探讨用什么方法来提高孩子们的语文成绩,我发言的题目是《曲径通幽话语文》,“径”就是方法、途径,用什么方法让孩子们达到语文幽雅、幽远而幽美的语文境地。 语文学习有两大目标:第一是为人生,第二是为应试。 就目前而言,应试离我们很近。虽然我们天天在批判“应试教育”,然而,既然高考还存在,我们就无法逃避它,而不管你是不是喜欢它。全国的高考方案有很多中,辽宁就经历过数学、语文、外语、物理、化学五科,数学、语文、外语、物理、化学、生物、政治、历史、地理等大综合,数学、语文、外语、物理、化学、生物等小综合几种,但不管是哪一种方案,语文都是主要考试科目,占150分。所以,我们不仅要学,而且必须学好它。 同时,语文是其他学科的基础,是学好其他学科必不可少的工具。英语也是语言学科,自然与语文有着密切的联系。政治、历史、地理同样离不开语文。即使是数学、物理、化学、生物,似乎与语文风马牛不相及了,其实,如果语文基础太差,要理解那些公式定理也非常困难。语文覆盖一切,穿透一切,训练的是人对一切文明符号的理解力和创造力。夸张点说,语文学好了,干什么都摧枯拉朽,势如破竹;语文学不好,干什么都愚昧弱智。 从更长远的角度看,语文是一个人一生中离不开的工具,不管你将来从事什么工作,听说读写的语文基本功都是不可缺少的,它将制约着你事业的发展和生活的质量。“才如江海文始壮,腹有诗书气自华!”学语文可以提高你的生活品位,陶冶你的情操,使你成为一个高尚而有生活情趣的人,一个内心充实积极乐观的人。语文学好了对于个人人格魅力的提升也有不可比拟的作用。唐代荆州长史韩朝宗才华横溢,李白钦佩他,作文道:“生不羡封万户侯,但愿一识韩荆州。”还有我非常喜欢冯延巳的《长命女》:“春日宴,绿酒一杯歌一遍,再拜陈三愿:一愿郎君千岁,二愿妾身长健,三愿如同粱上燕,岁岁长相见。” 多么有诗情话意。简简单单的一件事,如何说就体现了一个人的雅趣,这就是学语文的妙处。这都是学好语文的妙处。例如:少儿九班赵菁,全面素质突出,“全军成才十佳青年”,中科院博士生在读。所以,无论如何要学好它,作一个成绩好而又丰富的人。怎样学好语文呢,我讲五个方面的问题: 树立一个观念

2017年美国名校阶段中国大陆学生录取统计

2017年美国名校EA/ED阶段中国大陆学生录取统计 2017年美国大学入学的早申EA/ED学校已基本放榜。本文收集统计了几大名校在大陆的录取情况。这些数据来自于各学校公布的录取结果和经过验证的留学中介。这些数据虽然难免有一些不精确的地方,但是基本能够反映出美国藤校在中国大学录取的基本情况。 从这些数据来看,藤校在中国大陆的录取依旧集中在北京、上海、南京、深圳等几个传统的出国老牌重点中学。人大附中、北京四中、北师大附属实验中学、上外附中、南外、深中的学校领先优势依旧明显。在竞争越来约激烈的今天,这些老牌学校的信誉度无疑为美国大学看中。 其次,一些海外背景的国际学校在今年的早申录取中也是颇为引人注目。常熟联合学院UWC 和上海七宝德怀特中学分别有学生被哈佛和斯坦福录取,这两所学校今年都是第一届高三学生毕业。不过这些国际背景的学校能够在国际教育中杀出一条血路,还需要时间来检验。 第三,美国高中分流了部分国内优质生源。美高中国籍的学生中有人拿到哈佛、斯坦福、MIT等学校的Offer。这也给国内的学校带来一定的冲击。 哈佛大学 常熟联合学院UWC(1)、北师大二附中(1) 耶鲁大学 南京外国语(2)、深圳中学(1)、清华附中国际部(1)、上中国际(1) 普林斯顿大学 上外附中(1)、上中国际(1)、美高(未披露名字)1 斯坦福大学 华南师大附中(1)、上海七宝德怀特(1) 哥伦比亚大学

2013东北育才分流考试英语试题及答案(考纲))

2013东北育才分流考试英语考纲 一、词汇范围锁定为高中book1-5高考考纲范围内词汇及牛津英语7A~9B的部分词汇。 二、语法检测包括 1、定从、强调句 Between the two parts of the concert is an interval, _____ the audience can buy ice-cream. A. when B. where C. that D. which 句意:音乐会的两大构成部分中间有幕间休息时间,在这段时间里观众可以去买冰激凌。When引导的定语从句修饰an interval,when在从句中作时间状语。首先解析句子结构,判断从句类型,题干说“在音乐会中间有间歇,此时你可以买冰激凌。”题干的前半部分完整无缺,后半部分补充说明这个间歇你可以干的事,所以这是一个非限定性定语从句,先行词为interval,非限定性定语从句的功能就是对先行词进行补充说明。由于从句部分不缺少主干成分,而且interval表时间,所以正确答案为A. It is not how much we do but how much love we put into what we do______benefits our work most. A. who B. which C. that D. what 强调句型:It is/was +被强调部分+that连接句子的其他部分。答案选择C。 2、非谓语 ______ by a greater demand of vegetables, farmers have built more green houses. A. Driven B. Being driven C. To drive D. Having driven 本题考查非谓语动词。句意为:受对于蔬菜的更大量需求的驱使, 农民们建了更多的暖棚。空格处为句子的状语, 其逻辑主语为farmers, 与drive之间存在被动关系, 故用被动形式。 3、状从 you may have, you should gather your courage to face the challenge. A. However a serious problem B. What a serious problem C. However serious a problem D. What serious a problem 根据句意“无论你有多么严重的问题, 你都应该鼓起勇气面对挑战”, 而however表让步时其顺序应是:however + 形容词+ 主语+ 谓语。however做连接副词, 相当于no matter how,后接形容词或副词, 意为“无论、不管” , 引导让步状语从句, 其序为“however+形容词、副词+主语+谓语”。 4、情态动词&虚拟 John went to the hospital alone. If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told 考查虚拟语气。句意:约翰独自去了医院。如果他告诉我的话, 我会跟他一起去的。前一句是陈述语气, 说明动发生在过去, 而且后一句的主句已经是would have gone说明是
