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

艺术欣赏的特点,其实不过是借有限却有力的诱导物,让欣赏者利用他们的那些和特定的艺术形象有联系的生活经验,发挥想象,接受以至“丰富”或“提炼”既成的艺术形象。

无形的音乐是给人听的,可是听音乐的人能够觉得看见了其实不在眼前的什么。

有形的绘画是给人看的,可是,例如画出了汹涌水势的马远的《水图》,能够使人觉得仿佛听见了什么。

我一时找不到适当的词句来说明这种精神活动,姑且把它叫做“再创造”吧。

一切于人民有益而使人觉得有趣的艺术,它的创造者力图再现生活时,也不漠视欣赏者“再创造”的要求和作用。

欣赏者之于艺术的“再创造”,当然和演员之于剧本的再创造不同。

他不必像演员那样,把在头脑里构成的形象,利用可以使第三者分明感受得到的形式加以表现。

无论如何,欣赏者的脑力活动不可能左右实际上不以人的意志为转移的客观存在。

可是,欣赏活动作为一种接受感动以至接受教育的方式或过程,应该说不是在简单地接受作品的内容。

2017年广州荔湾广雅实验学校招生语文真卷(一)1.鲜为人知(xiǎn) 曲高和寡(hè) 枝折花落(shé) 称心如意(chèn)【点拨】考查学生对词语的准确拼读。

“曲高和寡”的意思是:旧指知音难觅。

现比喻言论或作品不通俗,能了解的人很少。

枝折花落的意思是:萧条、败落,也可形容房屋萧条或者形容一个人的身败名裂。

2.B【点拨】考查学生对词语的准确书写。

A.“融汇贯通”改为“融会贯通”;C.“箫索”改为“萧索”;D.“相得益章”改为“相得益彰”。

其中“相得益彰”的意思是:指两个人或两件事物互相配合,双方的能力和作用更能显示出来。

3.(1)义正言辞 (2)沁人心脾 (3)汗流浃背【点拨】考查学生对成语的灵活运用,不仅要会准确书写,还要知道成语的意思。

4.(1)父亲坚决地对母亲说:“我一定要回到祖国。

”【点拨】本题考查学生对直接引语与间接引语的转换。

做题方法:(1)注意改变人称,第一人称变第三人称;(2)主要改变标点,冒号变逗号。

(2)秋季草木稀疏,高远清澈。

【点拨】考查学生对对偶的灵活运用。

对偶是用字数相等、结构相同、意义对称的一对短语或句子来表达两个相对应或相近的意思。

【点拨】考查学生对对联的灵活运用,对联:要求对仗工整,平仄协调。

Her face is seen on stamps and coins all around the world.Elizabeth Alexandra Mary Windsor was born in London on April 21st 1926. Her parents were George, the Duke of York, and Elizabeth, the daughter of the Earl and Countness of Strathmore. As a child, Princess Elizabeth lived with her parents and younger sister in London and Windsor. Every summer, she traveled to Scotland to visit her mother’s parents. She was interested in all kinds of sports, but her favorites were horse riding and swimming. She was also keen on acting, art and music.As princess Elizabeth grew older, she started to play a part in British public life. When she was 14, she broadcast a radio message to all the children of Britain and the Common-wealth. Two years later, she carried out her first public duty, and started to go on official tours shortly after that. After a tour to South Africa in 1946, she married Philip Mountbatten. The couple had four children: Prince Charles, born in 1948, Princess Anne, born in 1950, Prince Andrew, born in 1960 and Prince Edward, born in 1964.After her father died, Princess Elizabeth became Queen Elizabeth II in a ceremony held in London in 1953.

When you see an apple or a piece of chocolate, you know that these are things you can eat. You can also use other senses when you choose your food.You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.36. What can learn from the passage?A. Humans and animals depend on one sense in choosing food.B. Humans and animals are not satisfied with their food.C. Humans and animals choose food in similar ways.D. Humans and animals eat entirely different food.37.

What can we learn from the last paragraph?A. Some people have few choices of food.B. Some people care little about healthy diet.C. French and British food is good for health.D. Modern people should spend a lot of time choosing their food.40. What’s the best tile of the passage?A. Like animals, like humansB. The more to choose, the more to eatC. Good choice, healthy dietD. Good taste, good for health(D)GONE WITH THE WINDAuthor: Margaret Mitchell¥25 (in bookstores) ¥18 (online)Gone With the Wind is a best-seller, which tells a story that happened in the American Civil War.
