许昌市三校联考高一上学期第二次考试语文试卷命题学校：长葛一高本试卷考试时间150分钟，分值150分第Ⅰ卷阅读题一、现代文阅读（9分，每小题3分）阅读下面的文字，完成1～3题。

“龙城”还是“卢城”①‚秦时明月汉时关，万里长征人未还。

但使龙城飞将在，不教胡马度阴山。

‛②这首传诵千古的《出塞》，抒发了王昌龄追昔抚今的感慨。

一般认为，诗中的‚飞将‛指西汉名将李广，他长期戍守北部边境，以勇敢善战著称，匈奴呼之为飞将军，一听到他的名字就畏惧、惊退。

那么，诗中的‚龙城‛又指何处呢？③历来唐诗集多作‚但使龙城飞将在‛。

清朝沈德潜《唐诗别裁集》也持此说，认为‚唐人边塞诗中所用的地名，有但取字面瑰奇雄丽而不甚考地理方位者‛。

此处的‚龙城飞将‛，‚乃合用卫青、李广事。

指扬威敌境之名将，更不得拘泥地理方位。

而诗中用‘龙城’字，亦有泛指边关要隘者。

‛就是说，‚龙城‛不过是象征性的地名，并非特指某一具体城邑。

④宋朝王安石《唐百家诗选》，将‚龙城‛改为‚卢城‛。

为何做此改动呢？阎若璩《潜邱札记》作了解释：‚李广为北平太守，匈奴号曰飞将军，避不敢入塞。

右北平，唐为北平郡，又名平州，治卢龙县。

唐时有卢龙府、卢龙军。

‛所以龙城就是右北平，应为卢城。

中国社会科学院文学研究所编写的《唐诗选》即取此说，将‚但使龙城飞将在‛改作‚但使卢城飞将在‛，认为卢城即现今河北卢龙。

但是，无论汉朝还是唐朝，右北平从来就没有称过卢城，只有《汉书〃西域传》中有一个无雷国，其国王‚治卢城，去长安九千九百五十里‛。

显然，此卢城不是右北平。

况且，《汉书〃卫青霍去病传》记载的那次威震敌胆的龙城大捷是卫青指挥的，并未提及与李广有关。

⑤清朝孙洙《唐诗三百首》引《晋书〃张轨传》的记载：匈奴曾筑姑臧城，‚地有龙行，故曰龙城‛。

据此说，‚龙城‛是指姑臧城，即今天的甘肃武威。

⑥张际在《‚龙城‛考》中则认为，据《史记》《汉书》等多处记载，龙城是匈奴祭祀龙神、祖先之地，地方并不固定，但在匈奴境内统称为‚龙城‛。

恒星考古：发现原始巨星踪迹①科学家们通过模拟早就预测到，第一代恒星中的某些恒星是非常巨大的，质量超过太阳质量的100倍，在仅仅几百万年的时间里就经历了生存和死亡，这个时间在宇宙中相当于一眨眼的功夫。

但天文学家们一直没有发现第一代恒星存在的迹象。

他们只能推测，那些恒星可能是在宇宙大爆炸发生之后最初的几亿年里形成的，由氢、氦和微量的锂构成，随着那些恒星作为超新星爆炸之后，产生了第一批重元素，通过这些重元素演化出了后来的星系和恒星。

②目前，利用一项被称为“恒星考古”的技术，日本国家天文台的青木和光及同事发现了这种恒星的首个迹象，这种迹象保存在其远古后代的化学成分。

第一代恒星的遗迹存在于一颗叫做S DSS J0018-0939的恒星中，其中的化学成分表明该恒星形成于一个气团，气团是由一颗非常巨大的恒星爆炸后所产生的材料构成的。

③第二代恒星燃烧较慢，已经存在了大约130亿年，它们中含有微量的较重的元素，这表明这些恒星是由一种气体聚结而成的，以前的一颗或数颗超新星产物使这种气体丰富起来。

“这就像柜橱里层的罐子中所盛的豆子，它们永远在那里呆着，但你可以随时打开” 剑桥市麻省理工学院的天体物理学家安娜弗雷贝尔说，“通过研究，科学家们能够将形成恒星的气体成分搞清，进而可以了解哪些成分以及各有多少成分来自于第一代恒星。

”④跟铁之类的较重元素相比，恒星S DSS J0018-0939中碳、镁和钙等较轻元素的丰度很低。

研究者对于这种特性，最有可能的解释就是一种叫做“不稳定对超新星”的特大质量恒星发生了爆炸。

⑤当恒星的核心温度变得非常高时，成对的光子变成成对的电子和正电子，这时就会形成不稳定对超新星，结果外表压力下降引起恒星产生明显的塌缩，发生巨大的热核爆炸。

AAre there any foreigners in your city? How do you address(称呼) them in English when you want to talk to these foreigners? The following may be some simple rules the beginners should follow.1.When talking to strangers there is often no special form of address in English. In most cases, if you want tocatch the attention of a stranger it is necessary to use such phrases as “Excuse me”.2.In British English “Sir” and “Madam” are considered to be too formal for most situations. They are usedmostly to customers in shops or restaurants .While in American English “Sir” and “Madam” are not so formal and are commonly used between strangers, especially with older peopl e whose names you don’t know.3.When you talk to some people you know, you can use their names directly. If you are friends, use their firstnames; if your relationship is more formal, use “Mr.”, “Mrs.”, “Ms.”, etc, before their family names.4.There are many other forms of address which can be used between friends and strangers. However, many ofthese are limited in use. For example, “pal” and “mate” can be used between strangers, but are usually only used by men talking to other men.If you meet foreigners, do remember not to address them in wrong ways.1. According to the passage, “Excuse me” is mainly used to _______.A. address a person you don’t knowB. apologize to othersC. catch the attention of a strangerD. suggest good manners2.

However, few people know that she was also the mother of a Nobel Prize winner.Born in September, 1987, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（设备）to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognized in the form of a Military’s Medal by the French government.In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（辐射能）. Irene Joliot-Curie died from leukemia on March 17, 1956.8. Why was Irene Curie awarded a Military Medal?A. Because she received a degree in mathematics.B. Because she contributed to saving the wounded.C. Because she won the Nobel Prize with Frederic.D. Because she worked as a helper to her mother.9. Where did Irene Curie meet her husband Frederic Joliot?A. At the Curie Institute.B. At the University of Paris.C. At a military hospital.D. At the College of Sevigne.10.When was the second child of Irene Curie and Frederic Joliot born?A. In 1932.B. In 1927.C. In 1897.D. In 1926.11.In which of the following aspects was Irene Curie different from her mother ?A. Irene worked with radioactivity.B. Irene combined family and career.C. Irene won the Nobel Prize onceD. Irene died from leukemia.DHoney from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper----a little bird called a honey guide.The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.12. Why is it difficult to find a wild bees' nest?A. It's small in size.B. It's hidden in trees.C. It's covered with wax.D. It's hard to recognize.13. What do the underlined words "the follower" in Paragraph 2 refer to?A. A bee.B. A bird.C. A honey seeker.D. A beekeeper.14. The honey guide is special in the way .A. it gets its foodB. it goes to churchC. it sings in the forestD. it reaches into bees' nests15. What can be the best title for the text?A. Wild BeesB. Wax and HoneyC. Beekeeping in AfricaD. Honey-Lover's Helper第二节（共5小题；每小题2分，满分10分）Public Speaking TrainingGet a coach__16__，so get help.

Are you hungry?” He said, “Yes.” I then asked, “May we buy you something to eat?” He responded with, “Sure, I can order something myself.”My husband opened the door and the gentleman went straight to the counter.

But people are funny. They think too much about the details.I had a secretary once. She was very hardworking. I ran a school and people used to call up to enroll for courses.

Y ou know how you feel to read over someone‟s shoulder?I read the page and leaned back. I guessed I was waiting for him to turn it. After a while, I realized—he wasn‟t turning the page. He just kept on reading.Now if you knew the page he was reading, you‟d know that there weren‟t many words on the page to read anyway. The layout was mostly pictures. So I turned to the man and said,” Y ou know, you really read very slowly.”“What do you mean?” he asked. “W ell,” I told him, “I read the page in about a minute, and you have taken about ten.
