Will it matter if you don't have your breakfast ? A short time ago , a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test . During the test , these people were given all kinds of breakfasts , and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had different kinds of breakfasts.
The rules show that if a person eats a right breakfast , he or she will work better than if he or she has no breakfast. If a student has fruit , eggs, bread and milk before going to school ,he or she will learn more quickly and listen more carefully in class.
The result is opposite to what some people think. Having no breakfast will not help them lose weight . This is because they are so hungry at noon that eat too much for lunch . They will gain weight instead of losing it . You will lose weight if you reduce your other meals.

Almost every family in America or England buys at least one copy of a newspaper each day. Some people buy as many as two or three different papers.
Why do people read newspapers?
Newspapers supply us with news about events in our hometowns, in our country, and in other parts of the world. Today we can read about important things that took place in foreign countries on the same day they happened, even in countries far away. But hundreds of years ago, news of things took months or even years to travel from one country to another. In those times, news was often passed from one person to another and never completely true. Newspapers today supply us with more than just what happened in our country or in other countries. If we want to know what the weather will be like, we can read the weather reports. If we want to find out what films are being shown, or what plays or concerts we can go to we can look in the newspapers.
In many countries people put notices in newspapers if they are trying to get a job, hunting for a house or rooms that they can rent, or even when looking for a person who is lost.
60. This article tells us ________.
A. most people in America or England read newspapers every day
B. all people in America or England read newspapers every day
C. every person in America or England reads newspapers every day
D. all families in America or England read newspapers every day
61. Newspapers supply us with ________.
A. only home news
B. only world news
C. home news and world news

62. Today we can read in our newspapers about important events________.
A. that took place hundreds of years ago
B. that took place in faraway countries soon after they happened
C. that will take place in foreign countries
D. that will take place in the world
63. Which is NOT TRUE according to the passage?
A. The habit of reading newspapers is found among most people.
B. Newspapers not only supply us with news from all over the world but also give us a lot of
useful information.
C. Hundreds of years ago news was not wholly true because it was told in spoken words.
D. If you have no place to live in, you can put notice in a newspaper and then you will certainly
get a room to live in.
C
In the US, pe ople prefer waiting for a table to sitting with people they don’t know. If you are sitting at a table with people you don’t know, it is impolite to light up a cigarette without first asking if it will disturb them.
At American restaurants and coffee shops you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill.
Most cities and towns have no rules about opening and closing times for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day.
Servings in restaurants are often large, too large for many people. If you can’t finish your meal but would like to enjoy the food later, ask your waitress or waite r for a “doggie bag”. It may have a picture of a dog on it, but everybody knows you’re taking the food for yourself. Supper and dinner are both words for the evening meal. Some people have “Sunday dinner”. This is an especially big noon meal.
Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.
64. Which statement is TRUE?

D. Restaurants may be open 24 hours a day in every city.
66. What do American people always do when servings are too large for them?
A. They leave the food on the table and go away.
B. They ask the waitress or waiter to keep the food.
C. They take the food home with a “doggie bag” for their dogs.
D. They take the food home with a “doggie bag” and enjoy the food later.

D
Do you know how to be happy? Here are six ways for you to find more pleasure in your life.
Play that song you love so much. As a preschooler can tell you, repetition can lead to pleasure. When you experience something more than once, you notice more details about it each time, and it increases your enjoym ent. That’s why you love revisiting that jazz club, favourite restaurant, and beloved old Woody Allen movie. Of course, you can overdo it.
Don’t buy boxed sets of DVDs. Economist(经济学家) Tyler says that much of the joy we get from our buying lies in the experience of finding them out, getting them home, and opening them up. If you receive 18 DVDs in one package, you’ll use up the excitement all at once. Buy things one a ti me and space out the pleasure.
Look outside. People long ago spent almost all of their time outside with trees, water, and sky around. The world in which most of us spend our time nowadays is unnatural and can harm the spirit. Even being close to nature for a short time can make us happy.
________. Physical contact with animals works wonders. You can pet an animal. It increases the brain chemicals connected with pleasure and decreases those connected with stress（压力）. Even people without pets can get some of the effect by hanging out for a few minutes at a dog shelter.
Smile. Well, like it or not, smiling improves your mood. Here’s why: people react better to you when you look happy, which in turn leads you to be happy. What’s more, looking happy fools your brain into thinking that you are happy.
68. According to the writer, buying things one at a time can ________.
A. helps us save some money.
B. spare time for other activities
C. increase our experience of happiness
D. give us more time to consider buying things.

B. Smiles fool others’ mood.
C. Animals add to your stress.
D. Spending time outside harms your spirit.
71. What is most likely to be discussed in the paragraph that follows?
A. The effect of pleasure on life.
B. The writer’s own experience.
C. Another way to find pleasure.
D. Reasons for finding more pleasure.

If the child has been brought up in a loving, openly communicative environment, the relationship with parents would be a strong one．It is only when there are ongoing troubles in the relationship between parents and the child that there is a breakdown in communication．
When parents are going through difficulties in their own relationship the child sometimes develops guilt．The child can hold himself or herself responsible for the breakdown in relationship between the parents．This needs to be explained to the child, who won’t speak out this guilt．
The teenage years are emotionally sensitive years to the outside world．For the first time the child realizes his or her position in society．Friends suddenly become more important than parents．It is during this time that the relationship between children and parents is tested．If the bond with parents is strong, the child will not be swayed by the drug and alcohol culture．If the bond is weaker, the child will end up with problems．
During such times, one of the effective ways to deal with the problems is to discuss the problem with the child．As parents, you will need to discuss the consequences of each option and then leave the final decision to the child．Forcing parental will on children is counterproductive (适得其反的), especially at this age．Imposing parental will at this time will stop communicating and then you will not know what is happening in their life．Whatever the problem is, the child need never be made to feel lonely．The moment that happens, the possibility of serious self-harm is raised．
Any problem at this age can be dealt with by a flexible approach by parents．Discuss things calmly．Leave the decision to the individual．Make yourself available for any help or support that the child desires．The child will feel comfortable when allowed the freedom of choice．
72. If parents have trouble with their relationship, the child ．
A．will feel guilty about the trouble B．will be responsible for the trouble
C．will communicate with their parents D．will help the parents recover
73. According to the text, what will lead the child to get into trouble?
A．the sense of responsibility．B．a weak bond with parents．
C．feeling depressed or stressed D．the child’s confidence．
74. The underlined word “ imposing” can be replaced with the word“”
A weakening．
B pressing．
C charging．
D losing．
75. What is the text mainly about?
A．The bond between parents and children．B．Causes of teenagers’ problems．
C．Teenagers’ problems and solutions．D．Always letting the children decide．
第Ⅱ卷非选择题
第一部分任务型阅读（共10小题；每小题1分，满分10分）
认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
注意：每个空格只填1个单词。请将答案写在答题纸相应题号的横线上。
You have probably heard it before, most likely from your English teacher. If you want to become a good writer, read good writing. Unfortunately, you may not have understood what did good to you and even what you were supposed to get from that experience.
As you start reading a book, poem, or story, do so with no thought at all and the experience will improve your writing. Just read for pleasure to begin with, or to learn. As you progress through the work, think about whether or not it is "easy" reading. Do you become so interested in the subject and flow of the writing that you completely forget the person who wrote it, or does the composition sometimes call too much attention to itself through words and phrases that seem out of place or unexpected? These latter situations are a chance to learn from the writer's mistakes. In fact, the reader should not have to worry about how an author does "his thing" ... he should be able to just enjoy and learn. Every time a word strikes you as poorly chosen, stop to consider why it has this effect. Also, do not spend a lot of time analyzing(分析) the passage but put more efforts in enjoying it from the whole.
Another thing I do, particularly with nonfiction（非小说）books, is to select a part to read as if it is a completely separate work. Once again, read as a common consumer rather than a critic (批评家). For learning how words and phrases work together on the most basic level, however, nothing is more suitable than your devotion to reading poems. A poet is often trying to put a book's worth of meaning and feelings into lines, and every side of the work shows a very close attention to craft（工艺）.
As you can see, there is no one simple way of reading to improve your writing. The key is not to make it boring. Select authors you admire or like most, and enjoy their works as anyone else would. As long as you are reading, you are improving yourself as a writer.
Title: Improve Your Writing by Reading
Facts ▲Reading good writing (76)___________ you become a good writher.
▲You don’t understand the (77)___________of reading and what to get from reading.
Ways ▲ Read not to learn but for (78)___________.
1)Develop a great (79)___________in the subject and flow of the writing.
2)Learn from the writer’s (80)___________if possible.
3)Too much (81)___________shouldn’t be spent in analyzing the passage but in enjoying the passage from the whole.
▲Read as a common consumer rather than a critic.
▲Be (82)___________ to reading poems and enjoy the lines.
Conclusions ▲Don’t make yourself (83)___________with reading.
▲Select your (48)___________authors and enjoy their works. ▲You are sure to (85)____________yourself during reading.

Great changes have taken place in my hometown in the past few years.
Just more than ten years ago, the streets in Hefei were crowded with little shops. There used to be rubbish everywhere, making the streets dirty and smelly. It was not suitable for people to live in. Many people wanted to move to other places.
But now with the economical and social development, the streets have been widened and on both sides of the streets green plants and flowers have been planted. Besides, many tall apartment buildings and parks have been built. People are paying more attention to environment protection and they are enjoying a much happier life here than before.

2017年5月20日陶冲湖语文考试题 作文题：（）最珍贵 阅读：鞭打心中的樱桃花 抽打心中的樱桃花 ①又到了樱桃上市的季节，见到妻子洗净放在茶几上红得晶莹透亮的樱桃，我不由得想起那树开满枝头的樱桃花。 ②年少时家中的院子里种了两棵樱桃树。有一年的春天，樱桃树开满了花，开得比以往哪一年都要多。蜂蝶在樱桃花间飞舞，馋嘴的我似乎已经闻到了樱桃那种特有的香甜味，就连在睡梦中，都是满树的樱桃在冲我微笑。 ③一天早晨，我还躺在床上，就听到院子里传来“噼里啪啦”的树枝摇晃的声响。从窗户看出去，竟看到母亲正拿着一根竹竿在樱桃花间抽打，其中的一棵好像已经抽打完了，樱桃花像下雨一样落了一地。她正准备抽打另一棵樱桃树。 ④我赶快跳下床，套上衣服，冲到院子，一把抱住了母亲。任凭母亲如何解释，我都紧紧抱住她的双臂不放手。母亲无奈之下只能住手，她说了一句意味深长的话：“也好，到了樱桃成熟的时候，你就知道我抽打樱桃花的用意了！” ⑤转眼间，樱桃花落了，两棵樱桃树都结满了青青的樱桃。尤其是我从母亲手中保护下来的那一棵，樱桃结得密密麻麻，数也数不清。我炫耀似的指给母亲看，她笑了笑，摇了摇头。 ⑥到了樱桃成熟的季节，那棵经母亲抽打的樱桃树硕果累累，一颗颗樱桃仿佛一盏盏挂在树上的小灯笼。而那棵未经抽打的樱桃树上的果实仍然是一片青绿。我坚持不吃已经成熟了的樱桃，静候着那片青绿变成点点唇红。 ⑦结果却是，已经成熟的樱桃被吃光了，我保护的那棵樱桃树仍是满树青黄，并且树上的樱桃开始干瘪、变黑、脱落，渐渐地树干上的绿色也退去，变得干枯，毫无生机。看着这样的结果，甲。母亲告诉我：“这棵樱桃树因为在春天花开得太多，又未经抽打，所以结的樱桃也太多。由于水分、营养供应不上，它累死了！” ⑧直到今天，我仍然记得母亲用牺牲一棵樱桃树的代价告诉我的道理：人活在世上是不能太贪心的，要学会取舍。心中贪念太多，只取不舍的结果，就像那棵未经抽打的樱桃树，最终导致你不堪重负、两手空空；而适当的舍弃，看似是一种失去，但在不久的将来，就会获得更加丰厚的回报！

安徽省合肥168中学2015届高三最后一卷 高三 2014-06-03 09:29 安徽省合肥168中学2015届高三最后一卷语文 本试卷分为第I卷（阅读题）和第II卷（表达题）。全卷满分150分，考试时间150分钟。 第I卷（阅读题共66分） 一、（9分） 阅读下面的文字，完成1—3题。 ①文学精神究竟是什么呢？机智灵动或犀利明快或繁复华丽的语言与此相关，生动曲折、波澜起伏的情节结构安排与此相关，敏锐、细微的点滴生活感受与此相关，正确的立意与思想观点也与此相关，但这些都加在一起，也不等于文学精神。 ②托尔斯泰在他的《艺术论》里说：“艺术是一种人类活动，其中一个人有意识地用某种外在标志把自己体验的情感传达给别人，而别人被这种情感所感染，同时也体验到这种情感。艺术既不是形而上者所说的某种神秘的思想、美或上帝的体现，也不是生理美学者所言的人们借以消耗过剩精力的游戏，也不是美好事物的产品，总之，并不是享乐，而是为生命和追求个人及全人类幸福的道路中必需的一种交际手法，它把人类联结在同样的情感中。”我们可以不同意托尔斯泰关于文学主要是情感的传达的说法，但是我们似乎不能不同意他说的真正的文学艺术不在于“外在的标志”，不只是一般的情绪的表达，不是游戏和享乐，而是作家生命的投入和为了个人和全人类的幸福，从而把人类联结在“同样的情感中”的活动，这同样的情感当然是指一种美好的情感。 ③我们的鲁迅，立足于他所处的中国近现代社会和文化的种种不良环境中，在早年就提出“能宣彼妙音，传其灵觉，以美善吾人之性情，崇大吾人之思理者”，为诗人之极致，提出文艺要表现和探索“理想的人性”。他在五四时期，又指出文艺是“引导国民精神的前途的灯火”。这“灯火”，就是中国现代文学的精神的火焰，并且实际上还不限于对“国民”而言，而与他当年高扬的欧洲诗人拜伦、雪莱的精神之火相接，是照见全人类走向自由解放之途的灯火。我过去写的《论“文学是人学”》，就受到过往哲人的启发，表示相信文学艺术“最基本的推动力，就是改善人性、把人类生活提高到至善至美的境界的那种热切的向往和崇高的理想”。具体而言，其最低标准是一切为了解放人、提高人的人道主义精神，这也可以说就是把人们联结在一起的那种“同样的情感”。我认为如果没有这点精神，文学就仅存形体（或许是美的形体），而没有多少吸引人、感染人的魅力了。
