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，完成下面3个小题。

在杂剧产生以前，正统的诗文一直占据着文坛的统治地位，而宋元时期戏曲小说的逐渐勃兴，可以说从根本上改变了这种状态。

读元明杂剧，既要看到它与我国传统文学艺术的联系，更要注重它的特殊性。

说到联系，我们不能不注意到古老的诗歌传统对元明杂剧的深刻影响，它首先是诗的戏剧，是“美文舞蹈的、诗韵兼全的”一种艺术形式。

元明杂剧不仅汲取了诗词歌赋的韵律之美、意境之美，还熔铸了诗的灵魂和精神。

只要认真读一读《西厢记》《汉宫秋》等杰作中优美的曲词，就不难领略到这一点。

如明人何良俊评郑光祖的《倩女离魂》之〔圣药王〕曲曰：“清丽流便，语人本色；然殊不浓郁，宜不谐于俗耳也。

”然而，元明杂剧毕竟是一种新的艺术形式。

它的曲词必须与情境、矛盾冲突以及人物形象塑造有机结合起来，甚至必须与表演艺术水乳交融。

《元曲选》的编订者臧晋叔谈到：“词本诗而亦取材于诗，大都妙在夺胎而止矣。

曲本词而不尽取材焉，如六经语、子史语、二藏语、稗官野乘语，无所不供其采掇，而要归断章取义，雅俗兼收，串合无痕，乃悦人耳。

”杂剧展现的是广阔的社会生活画面，故须兼收并蓄，雅俗共赏，便是所谓“情词稳称之难”。

王国维激赏《窦娥冤》第二折的〔斗虾蟆〕等曲，说：“此一曲直是宾白，令人忘其为曲，元初所谓当行家，大率如此。

”王国维是真正读懂读透了元曲，他不仅将其当作戏剧的文学剧本来读，且当成美文来读：“由是观之，则元剧实于新文体中自由使用新言语，在我国文学中，于《楚辞》《内典》外，得此而三。

We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year Perth has the wild flowers' exhibition. After visiting Perth, we spent the day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves. Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and runback to the car as quickly as we could.

My brother and I were not very excited when we realized what our mother meant. What she meant was not that we could take drawing classes or painting classes but that we would have to spend our afternoon a week with her at the Fine Arts Museum. Before each visit to the museum, she made us read about artists and painting styles.about artists when you could be with our friends at the swimming pool?First we had to read about ancient Egyptians and their strange way of painting faces and then go to look at them at the museum. My 12-year-old brother thought thiswas funny, but I was not interested. Later we had to learn about artists in the Middle Age who painted people wearing strange long clothing. We had to look at pictures of fat babies with wings and curly hair and with no clothes on flying around the edges of paintings. I certainly couldn’t see what was so great about art.On our last visit to the museum, things changed when I saw a painting by a womanand you could tell by the woman’s expression how happy she was just to be with the child. I couldn’t stop loo king at the painting! I wanted to see every painting Mary had ever made! It was really worth looking at so many paintings to find a painter who could interest me so much.8. The purpose of the mother’s plan for her children was to ________.A. take them to visit the museumB. ask them to read about artistsC. show them different painting stylesD. introduce them to the world of art9.

The change.DWhen I first started university，I remembered hearing about bone marrow（骨髓）donation during Freshman's Week．Some students volunteers from a group called Marrow tried to convince me to attend an event so I could learn more about it．The word"bone"immediately made me think that donating would be a painful procedure，I am currently waiting to be matched with a donor and if I am lucky enough to find a good match，it will be this lovely stranger that saves my life．I received my cancer diagnosis in June．It is only at that time that I realized how ignorant I had been about the bone marrow donation process．The process of donating stem cells is actually very simple．In 90% of cases，donors are asked to donate their blood stem cells，the other 10% will give their bone marrow．Lots of donors say that both these things are virtually pain free，and nothing to be scared about．Being a bone marrow donor should be something to be proud of，as every donor has an opportunity to save someone's life!At the moment I know that the doctors are busy searching for a match，I simply live every day in the hope that there will be a donor right for me．If I have an opportunity for life，I won't waste it．When I was a first year at university，I made the mistake of walking away from becoming a stem cell donor．Please don't make the same mistake that I did．There are so many people out there，including myself，that need your help； and by undergoing a simple，pain﹣free procedure，you could have the chance to proudly say that you saved someone's life．12．Why did the author refuse to learn more about bone marrow donation before？A．Because she could get nothing from it．B．Because she was in poor health．C．Because she had known nothing about it．D．Because she thought that donating would be painful．13．What can we learn from the underlined sentence in paragraph 1？A．The author was concerned about others．B．The author was confident about the bone marrow donation．C．The author needs the bone marrow donation now．D．The author donates her bone marrow to save others．A．headache B．cancer C．flu D．high blood pressureA．show us the experience of her college life．B．explain the cause of her cancer．C．recall her painful past．D．encourage people to be a bone marrow donor．第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

My brother and I were not very excited when we realized what our mother meant. What she meant was not that we could take drawing classes or painting classes but that we would have to spend our afternoon a week with her at the Fine Arts Museum. Before each visit to the museum, she made us read about artists and painting styles.about artists when you could be with our friends at the swimming pool?First we had to read about ancient Egyptians and their strange way of painting faces and then go to look at them at the museum. My 12-year-old brother thought thiswas funny, but I was not interested. Later we had to learn about artists in the Middle Age who painted people wearing strange long clothing. We had to look at pictures of fat babies with wings and curly hair and with no clothes on flying around the edges of paintings. I certainly couldn’t see what was so great about art.On our last visit to the museum, things changed when I saw a painting by a womanand you could tell by the woman’s expression how happy she was just to be with the child. I couldn’t stop loo king at the painting! I wanted to see every painting Mary had ever made! It was really worth looking at so many paintings to find a painter who could interest me so much.8.

The change.DWhen I first started university，I remembered hearing about bone marrow（骨髓）donation during Freshman's Week．Some students volunteers from a group called Marrow tried to convince me to attend an event so I could learn more about it．The word"bone"immediately made me think that donating would be a painful procedure，I am currently waiting to be matched with a donor and if I am lucky enough to find a good match，it will be this lovely stranger that saves my life．I received my cancer diagnosis in June．It is only at that time that I realized how ignorant I had been about the bone marrow donation process．The process of donating stem cells is actually very simple．In 90% of cases，donors are asked to donate their blood stem cells，the other 10% will give their bone marrow．Lots of donors say that both these things are virtually pain free，and nothing to be scared about．Being a bone marrow donor should be something to be proud of，as every donor has an opportunity to save someone's life!At the moment I know that the doctors are busy searching for a match，I simply live every day in the hope that there will be a donor right for me．If I have an opportunity for life，I won't waste it．When I was a first year at university，I made the mistake of walking away from becoming a stem cell donor．Please don't make the same mistake that I did．There are so many people out there，including myself，that need your help； and by undergoing a simple，pain﹣free procedure，you could have the chance to proudly say that you saved someone's life．12．Why did the author refuse to learn more about bone marrow donation before？A．Because she could get nothing from it．B．Because she was in poor health．C．Because she had known nothing about it．D．Because she thought that donating would be painful．13．What can we learn from the underlined sentence in paragraph 1？A．The author was concerned about others．B．The author was confident about the bone marrow donation．C．The author needs the bone marrow donation now．D．The author donates her bone marrow to save others．A．headache B．cancer C．flu D．high blood pressureA．show us the experience of her college life．B．explain the cause of her cancer．C．recall her painful past．D．encourage people to be a bone marrow donor．第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
