4.命题范围:高考范围。

第I卷(阅读题共70分)甲必考题一、现代文阅读(9分,每小题3分)阅读下面的文字,完成1~3题。

自魏晋以来,在玄学思潮的推动下,开创了在文学创作中追求言外之意、弦外之音、象外之趣以及言有尽而意无穷的美学旨趣。

中国古代诗歌理论对此有大量论述,这是众所周知的。

由此,许多人认为,这是中国古典美学和诗歌理论独有的特征,因而不同于西方美学理论重视文学作品严密的逻辑性和理性的分析,不重视以有限的形式容纳无限的内涵。

但事实并非如此,现代西方接受美学理论指出,一部文学作品中总是存在许多意义空缺部分。

德国康士坦茨学派的伊瑟尔认为,作品本身是作家有意识活动的产物,只能部分地左右读者的理解和反应,其中总包含一些“空白”或“不明确的因素”。

这一点在现代文学中尤其明显。

伊瑟尔在《隐含的读者》一书中,从对英国古典作家班扬到现代作家贝克特的作品进行的历史考察中,发现这几个世纪以来,西方文学作品总的趋势是“空白”和“不确定性”越来越多,因而要求读者在阅读过程中必须有主观因素的积极参与。

西方现代接受美学也把追求空白和不确定性,作为衡量文学作品艺术水准高下的重要尺度。

上述事实都说明,重视文学作品的言外之意、言不尽意和以少寓多,并不只是中国古典美学和诗学的特征,而可以说是人类审美的普遍现象。

这一人类经验的普遍特征,同人类语言的特点有着内在的联系。

AIt was Saturday morning. I heard loud noises of moving furniture in the next room. I could almost feel the excitement of John who was soon going to get a room of his own. I remember my own feelings when I was 13. I knew how much he longed for his right to privacy (私人空间) when he was sharing a room with his younger brother, Robot. He said, “Mum, Can I please have a room of my own? I could use Jeff’s. He won’t mind.”It was true that Jeff had graduated from college and flown from the nest. But would he mind? The room was the place where I told him a thousand stories and we had a thousand talks. As close as we were, though, the time came when Jeff needed a door between us. His life was spreading into areas that had less to do with family. I no longer could-or should-know everything about him.It turned out that getting Jeff’s permission was easy. He said, “Of course, Mum, it would be selfish of me to hold on to it.” Then his voice softened, “Mum, I won’t be living at homeagain---you know that.” Behind his glasses, his eyes were lit with all the love. There were no door closed here---they had all opened up again.As John and I were cleaning the room, I fixed my eyes on Jeff’s things around me and could almost touch the little boy I knew was gone forever. I looked at the room and, in my heart, I let it go. To hold on would be, as Jeff said, selfish. Now it was time for John, shouldering through the door, his eyes bright with promise of independence, to disappear behind the door. It was time for letting go to happen again.21. Which of the following is TRUE according to the passageA. John was moving to live with his brother.B. John was eager to get a room of his own.C. Jeff volunteered to give his room to John.D. Jeff refused to let his brother have his room.22. The underlined sentence in the second paragraph probably means “______”.A. Jeff finally flew out of the houseB. Jeff would have less to do with his familyC. Jeff needed his right to privacyD. Jeff got tired of those familiar stories23. How did the author feel about her children’s sense of independence?A. Delighted.B. Jealous (嫉妒的).C. Confused.D. Embarrassed.24. It can be inferred from the passage that ______.A. the children did not like to live with adultsB. all her three kids made the author feel depressedC. none of the members in the family thought the same wayD. the author loved and missed the time together with her kidsBIf you want to write a movie script (脚本) yourself but don’t know how, what would you do? The following can be of some help to you.There are only three parts necessary in a script: the Scene Heading, the Visual Exposition and the Dialogue.The Scene Heading begins with either “EXT.” or “INT.”. EXT. shows that the scene takes place outdoors, while INT. is used when the scene takes place indoors, for example, inside a room. After that, the exact place of the scene is given, such as “HOTEL ROOM.” The last thing that must be mentioned is whether it is NIGHT or DAY.The Visual Exposition is a description of the action or movement that takes place on the screen, and should include ONLY what you would see if you were watching the screen. For the first time, and only the first time, a character appears in the script, the name is capitalized (大写), and should be followed by a short description that includes age and build, for example:The Dialogue follows the Visual Exposition. Each character’s name should be capitalized in the center of the page, followed by the words that are to be spoken on the next line. Do not include any description of feelings before the lines of dialogue. If you consider it necessary to show a character gives a line in a certa in way, for example, “angrily,” this should be included in the Visual Exposition above the lines, such as, “Cynthia’s face shows her anger.” But remember, Visual Exposition should ONLY show action we can see.25. In a script the Scene Heading tells _________ the story takes place.A. where and whenB. at what time of a dayC. what has happened whenD. on which day of the week26. If a story takes place in a park on a Friday morning, which of the Scene Headings is right?A. INT. FRIDAY-DAY.B. EXT. FRIDAY-NIGHT.C. INT. PARK-NIGHT.D. EXT. PARK-DAY.27. The Visual Exposition in a script only includes actions or movements _________.A. that some main characters doB. that can be seen on the screenC. that the writer of the story describesD. that happen in outdoor activities28. Which of the following short scripts is right?A.D.CIf man’s best friend is a dog, then who is a dog’s best friend? That would be Rover, Glow, Ivan, or Raina. These four recently donated valuable pints (品脱) of blood to their fellow dogs. And they did it without having to travel far from home. They visited an animal bloodmobile (采血车).Similar to the Red Cross vehicles for human beings, the University of Pennsylvania’s travelling veterinary (兽医的) lab goes to where the donors are to make it easier. The bloodmobile makes weekly rounds through suburban Philadelphia and New Jersey. Kym Marryott, manager of Penn’s Animal Blood Bank, said, “You don’t really think about it until you actually need it. Just like us, dogs need blood too.”However, not every dog can donate blood. The dogs are examined for health first. Dogs must have the correct blood type, weigh at least 55 pounds and be younger than 8 years old. About 150 dogs participate in the program. Each donates three or four pints a year, which can help animals suffering from illnesses like cancer or an accidental injury like being hit by a car. One pint can save up to three dogs.Sandy Lucas brought her 7-year-old black German shepherd, Raina, to the bloodmobile last week when it parked at a mall in Harleysville, Pennsylvania. The resident(居民)said she wouldn’t have braved highway traff ic and city parking problems to take the dog to Penn Vet’s Animal Hospital in downtown Philadelphia, which is too far from her home. But the bloodmobile made it convenient to find out if Raina could donate. “I was very, very thrilled when I knew she had th e right blood that was needed to help another dog out,” said Sandy Lucas. “We’ll definitely do it again.”Just like human beings, the donors (捐助者)get a snack and a heart-shaped “U of P Blood Donor” sticker immediately after giving. In addition, they receiv e free blood checkups and dog food to take home.29. To bring convenience to the donors, the lab __________.A. has bloodmobiles visiting the suburbsB. is built where the donors areC. goes to the homes of the donorsD. works with the Red Cross30. How many factors should be considered when making donations?A. Two.B. Three.C. Four.D. Five.31. The example of Raina is mentioned in the passage to __________.A. stress the importance of keeping petsB. prove the value of bloodmobilesC. tell readers that Raina is very braveD. show how its owner felt then32. After giving donations, the donors __________.A. are offered a stickerB. receive a free physical checkupC. get a bag of free bloodD. feel very thrilledDIn this influential work about the surprising divide between children and the outdoors, child supporter expert Richard Louv directly links the lack of nature in the lives of today’s wired generation ---- he calls it nature-deficit(赤字) ---- to some of the most disturbing childhood trends, such as the rises in obesity, attention disorders, and depression.Last Child in the Woods i s the first book to bring together a new and growing body of research indicating(表明)that direct exposure to nature is essential for healthy childhood development and for the physical and emotional health of children and adults.
