Theaters of the Past

The Greek Theater

Theaters developed in many parts of Greece. Ancient Greek theaters were built in natural open air sites on conveniently shaped hills. This allowed a great mass of people to enjoy a show at a time. Due to this, actors placed emphasis on exaggerated(夸张的) action and speech. And, colorful symbolic masks and costumes were used.

The Medieval Theater

The Medieval theater started in churches. That’s why medieval plays were about Bible stories. At first, it became a custom for priests (牧师) to act out brief scenes during Christmas and Easter. These acts attracted large crowds. Finally the church refused to allow priests to participate in any such events again, so ordinary people began these performances outside. Performances were set in the town square, with several stage settings around it.

The Elizabethan Theater

The England’s theater developed rapidly in the years following t he defeat of the Spanish Navy. The dominant

feature of Elizabethan theater was the stage, It has three parts :The fore stage for outside scenes ;the inner stage for scenes inside a building; an upper stage or balcony for various purposes. The reason for this design is that there were no scene changes, or breaks during the play. Very little scenery was used, so the actors had to create a scene through their voices and dialogues. This led to a more poetic script , and poets became the main source of script writing.

The Restoration Theater

Some of the plays told sad stories, but the majority of the plays were really funny. Many specialized machines were used to create the scene. The stage was a very clever idea , in that on the sides of the stage large back shutters(百叶窗) were painted with the scene.

2 l. Why were ancient Greek theaters built on hills?

A. To hold a large audience.

B. To build a big and strong stage.

C. To have a better sound effect.

D. To emphasize exaggerated performances.

22. In which the ater could actors’ voices and speech help create scenes?

A. The Greek Theater.

B. The Medieval Theater,

C. The Elizabethan Theater,

D. The Restoration Theater.

23. What is special about the Restoration Theater?

A. Colorful masks were used.

B. The stage was smartly designed.

C. Most of its plays were sorrowful.

D. Ordinary people were the performers.

Semi-retired advertising agency owner Stephen Thomas, 58 , has been investing on and off for the past 30 years. He made money in the.dotcom boom but got his fingers burned when the bubble burst in March 2000. When he got access to his pension he decided to start investing again, this time with the help of his son Sam.

Now the tw o meet up most afternoons at Stephen’s home in Sandbach , Cheshire to talk about investments. The day starts at 7 am when Sam looks at company announcements online. These regulatory announcements can include a firm’s accounts , general updates or news of mergers(合并) or acquisitions.

Each has an ISA (Individual Savings Account) with AJ Bell , which they use to buy individual stocks and shares.

They have invested in oil companies and pet care businesses , to name just a few. But while the investments of the two men are similar, they do have different approaches. While Sam likes to hold shares for the long term as he is saving money for his future retirement , Stephen likes to buy with any profits he makes.

Sam says, “We do not argue because we have separate ISAs. It means finally we make our own decisions about which shares to invest in. The only time we might have a disagreement is when we both want to use the login for the news service at the same time.”

24. What happened to Stephen in 2000?

A. He had to retire from the agency.

D. He suffered a loss in his investment.

In today’s society , language plays a key role in defining gender (性别) by vocabulary, and also their non-verbal

(非语言的) vocabulary. Each one of these different types of ways of communicating is obviously different between men and women.

Many different studies show that men tend to talk much more than women. It has also been proven that women tend to speak faster than men; this is due to the fact that women tend to be interrupted more often than men are, and also have the ability to speak more clearly, precisely, and more quickly than men. In one study it was found that women spoke for an average of three minutes describing a painting, as opposed to the thirteen-minute average it took men to describe it.

Men and women also tend to have a very different non-verbal way of communicating, which can also make it very hard for one another to understand what the opposite sex is trying to say. Men’s body language is much more reserved when talking to women. Men tend not to make as much eye contact and they generally stay farther away from women when talking to them. Men avoid other people’s body space while talking, and they also tend to sit back when talking. All of these have given off the impression of disinterest or boredom. Women are by far better listeners and much more enjoyable to talk with and they tend to raise more topics for conversation.

Women also make it clearer whether or not the conversation is going somewhere or just stuck in neutral. After learning about our styles of communicating with each other, I have decided that although men have not quite mastered communicating, what fun would it be if we all spoke the same “language”? The little games men and women play with each other while conversing would be lost. The question everyone asks himself or herself after talking with someone of the opposite sex, “I wonder if there’s something there?” would no longer exist.

28. What does the underlined word “this”in Paragraph 2 refer to?

A. The differences between men’s and women’s la nguages.

B. The different speed of men’s and women’s speech.

C. The ability of men’s and women’s spoken language.

D. The non-verbal vocabulary of men and women.

29. In what way do men and women differ according to the third paragraph?

A. Speed of understanding.

B. Understanding of speech roles.

C. Politeness of communication.

D. Application of body language.

30. What is the author’s attitude to the differences between men’s and women’s communication?

A. Cautious.

B. Favorable.

C. Ambiguous.

D. Skeptical.

31. What is the best title for the text?

A. Women , born excellent talkers

B. Men’s and women’s social roles

C. V ocabulary and communication

D. Opposite gender, different language

D

It’s not every day that United States history mixes with microbes (微生物) in the soil. But when the grassland on the National Mall in Washington, D.C. was replaced, it offered scientists the opportunity to study changes in the soil beneath.

The work focused on the bacteria present in the soil. To the researchers’ surprise, the communities of microbes did not change a lot before and after the replacement. These communities in the soil are known as the soil microbiome (微生物群).

“My lab is interested in how microbes can move around in the environment , and how they change and adapt as a result of this movement,” explains Jo Anne Crouch, the lead author of the study. “We thought that the new

‘imported ’turf (草皮) from New Jersey would introduce different communities of bacteria to the National Mall. However, we found that they weren’t significantly different.”

Crouch’s work focused on turf grass ,defined as a large area of green grass. It is made up of the grass, its roots, and the soil and microbes found with them.

Think of the soil microbiome as similar to the collection of microbes found in the human body. When the microbes are out of balance , it can make someone sick. Crouch says it’s the same for the soil microbiome. Many of the worst diseases in crops or other environments are linked with changes in the soil microbiome.

Additionally, Crouch says that even though the changes between the soils were small, scientists are also starting to appreciate that sometimes a really important microbe is a rare one. This means it would be hard to observe but could greatly affect how the groups function as a whole. “Agricultural areas and other natural spaces are highly and easily hurt by negative changes,” she says. “Microbiomes offer an almost entirely new opportunity to influence interactions among plants and microbes to improve plant productivity and health. ”

32. Why did the researchers feel surprised when they focused on the bacteria in the soil?

A. More bacteria appeared in the soil.

B. Microbes were replaced obviously.

C. Soil microbiome almost remained stable.

D. The soil microbiomes damaged the environment.

33. By studying the turf grass , what did Crouch and her team find?

A. Microbes grew faster in their own community.

B. Soil microbiomes were different in different places.

C. Turf grass adapted to the environment nearby very soon.

D. Similar communities of bacteria were brought by turf grass.

34. Why did the author mention the microbes in the human body?

A. To indicate the two play a similar role.

B. To prove they are both the causes of diseases.

C. To examine the environments people live in.

D. To analyze the changes of human microbes.

35. What does Crouch mean in the last paragraph?

A. Microbes are still as hard to observe as before.

B. Studies on microbiomes can be beneficial to agriculture.

C. Scientists are still puzzled about the effect of microbiomes.

D. Too many microbiomes in the soil mean no harm to plants.

What to Do When Someone Doesn’t Like You

When someone tells me , “I don’t care if people like me,” they are showing me the emotional wall they use to block the hurt of rejection.

As humans are social animals, all of us care if people like us. Based on the need for social connection, your reactions to rejection and negative judgment can range from minor hurt to breakouts of depression. 36 The first step to handle a negative situation is to recognize your reaction. Ask yourself, “What am I feeling?”.

37 Any betrayal (背叛) or embarrassments in your heart? Identify what feeling has shown up in your body? so you can choose what to do next.

38 When you sense yourself shutting down or feeling defensive, ask yourself what the person actually meant to do to you, Did they truly mean to offend you, or make fun of you ? Your brain works very hard to keep you safe , so it will judge a situation as threatening if there is any possibility of social harm.

When our brains sense a possible threat, we react as if we were personally attacked. Take a breath to relieve the stress, 39

Finally, if you be lieve the person doesn’t like you , ask yourself if this matters. 40 If not, what can you do to release your need to be liked by this person? And, what can you do to stay neutral and not return the dislike? The more you can come to accept others as who they are , the more you can move forward with your goals regardless if someone likes you or not.

A. If you can , look the person in their eyes.

B. Do you feel any fear or anger in your head ?

C. Ask yourself what is true about the situation.

D. Often people do not realize the impact of their words.

E. Will the person’s judgment of you impact your work or life?

F. The ability to let a show of dislike roll off your back is a learned skill.

G. This will ground you in the present and take you out of your trembling mind.

安徽省合肥市2018年高三第三次教学质量检测 语文试题 注意事项: 1.答题前,务必在答题卡和答题卷规定的地方填写自己的姓名、准考证号和座位号后两位。2.答题时,每小题选出答案后,用2B铅笔把答题卡上对应题目的答案标号涂黑。如需改动,用橡皮擦干净后,再选涂其他答案标号。 3.答题时,必须使用0.5毫米的黑色墨水签字笔在答题卷上书写,要求字体工整、笔迹清晰。作图题可先用铅笔在答题卷规定的位置绘出,确认后再用0.5毫米的黑色墨水签字笔描清楚。必须在题号所指示的答题区域作答,超出答题区域书写的答案无效,在试题卷、草稿纸上答题无效。 4.考试结束,务必将答题卡和答题卷一并上交。 一、现代文阅读(35分) (一)论述类文本阅读(本题共3小题,9分) 阅读下面的文字,完成1~3题。 20世纪的中国文学,基本是在作为一个框架的“中国”内部展开,是对这个框架内部的个人或群体的书写,而此框架本身并未成为作家们自觉描写的对象。“中国”可以表现为人,可以表现为山川大地,可以表现为辽阔的疆土,也可以表现为悠久的历史。但综合来看,对于“中国”的书写表现出发散性的特点,“中国”基本并未作为一个融贯的理念,更很少作为一个文明体得到呈现。 当下中国所处的历史方位被命名为“新时代”,这一命名具有深远的文明史意义。而作为创造新文明之主体的“中国”,将越来越鲜明地成为一个意蕴深远的理论概念,成为我们向远方眺望的基本视野。由这种视野出发的新时代文学,也将具有越来越鲜明的纵深感,并最终在客观上将自身发展成为表现新时代之本质性和整体性的史诗。 “新时代”具有深远的文明史意义,这并不是说当中国进入新时代后,就化解了所有的矛盾和问题,以一种文明的完成时态而存在。新时代对新文明的创造是一个正在展开的过程,这个未有穷期的动态过程包含一种内在的张力,即它一方面在本质上表现为批判、推动现有文明进程的创造性和超越性,另一方面又在具体的现实问题上表现出一系列矛盾。 立足于现实中的各种矛盾和问题来展开文学世界,这是20世纪中国文学的传统,也是当下文学的基本特点。臵身于社会矛盾的漩涡中,将自己的笔投向现实问题的更深处,揭示复杂的人性和丰富的痛苦,这应该是作家的底线,也是作家良知的根本体现。直面矛盾,直面现实,从文学内部思考同时代的重大问题,也正是20世纪中国文学的基本传统。在新时代,社会主要矛盾内容的转化会带来文学题材和美学形态的变化,比如乡土文学和都市文学的消长、生态文学和科幻文学的涌现等等。但是,“真诚地深入地大胆地看取人生”“写出国人的灵魂”,这些由鲁迅所高扬的伟大的现实主义精神,仍将是新时代作家不可忘记的创作指南。而且随着人民在物质和精神生活上更普遍更深入的要求的提出,也由于生产力不充分尤其是不平衡的状况的存在,社会矛盾给人的内心刻下的印痕更为深隐也是可能的。这就更要求新时代的作家继续“真诚地深入地大胆地看取人生”。 “新时代”给当下文学所带来的挑战还表现在作家如何在自己的作品中,去触及乃至包含“新时代”所具有的文明史意义这一议题。而当我们意识到作为一种整体性的新文明的担纲者只能是“中国”这一综合性的主体的时候,则问题又转化为新时代的作家如何崔自己的
