For each question there are four suggested answers marked A. B. C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.The wheel was one of man's first inventions and yet it has also proved one of the most useful. So wide and varied are the uses of wheels, in machines and vehicles of all kinds, that it is difficult to imagine what the world would be like without them. It is surprising to hear it said, therefore, that the wheel's importance will perhaps be greatly reduced by the end of he century by an invention so new as to be still unnamed.The invention is a machine that floats above any surface on a cushion of air. The cushion is formed when air is blown into the bottom of the machine. This part is shaped like a saucer turned upside down. If air is blown into this saucer, the machine rises to a height that may vary from a few inches to a few feet.Industry is already using one form of the invention to deal with heavy loads. It can lift them with ease and since there are no wheels, and therefore no friction, they can be put into motion with the touch of a finger.The new invention, however, is having a great effect on transport. Not only does it make expensive road systems unnecessary, but it enables vehicles to travel equally well over land or water. This unique ability to reach most destinations has given rise to the prediction that wheeled vehicles may be as uncommon at the end of the century as aeroplanes were at the beginning.76. The first paragraph tells us that ________ A the wheel was man's earliest invention B wide wheels have a variety of important usesC the wheel's usefulness ahs yet to be proved77. The phrase "with the touch of a finger" in the third paragraph means ________B without frictionC by electricityD by hand78. The passage tells us that the new invention ___________A is more important for industry than for transportC will one day be used instead of aeroplaneD will replace wheeled vehicles in a hundred years79. At the end of the century, vehicles using the new invention will probably be __________A rareB unimportant D expensive80. According to the passage, the new invention ________A will soon get a nameB is lighter than air D was uncommon a century agoPassage two We have no idea about when man first begin to use salt, but we do know that it has been used in many different ways throughout the history. For example, it is recorded in many history books that people who lived over three thousand years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve the dead.In some periods of history, a person who stole was thought to have broken the law. Take the eighteenth century for example. If a person was caught stealing salt, he would be thrown into prison. History also records that only in England about ten thousand people were put into prison during that century for stealing salt! About one hundred and fifty years before, in the year 1553, if a man took more than his share of salt, he would be thought to have broken the law and would be seriously punished, and his ear would be cut off.Salt was an important item on the dinner table of a king. It was always placed in front of the king when he sat down to eat. Important guests at the king's table were seated near the salt. Less important guests were given seats farther away from it.81. Thousands of years ago in Egypt salt was used ___________.A to punish people who has broken the law C to keep fish alive D to make chemicals82. During the 18th century about ten thousand people were put into prison in England because _________.B they had sold salted fishC they had taken salt from the king's tableD they had used salt to preserve dead bodies83. In the __ century, a man who took more than his share of salt would ________A fifteenth; lose all his saltB fifteenth; be thrown into prisonC fifteenth; lose an ear84. When a king had his dinner, salt was placed _________A in front of the important guestsB far away from him D nearer to the less important guests85. The best title of the passage is __________A Nobody Knows When Salt Began to Be UsedC Thousand of People Were Punished because of SaltD Salt Was Important in HistoryThere was a businessman who always tried to pay as little as possible for what he needed. One day he fell ill. He decided to go to a doctor and asked a friend to recommend one."Dr Smith is a good one," the friend told him."Is he expensive?" the businessman asked."Yes and no. He charges five hundred dollars for the first visit, but only twenty-five dollars for each visit after that.""That seems reasonable," the businessman said, and went to visit Dr Smith.As he walked into the consulting-room, he said, " Well, here I am AGAIN," and put twenty-five dollars on the table.The doctor looked at him carefully for a moment, then smiled and put the money into the drawer of his desk. "Thank you," he said. "And what can I do for you today?""Examine me, of course," the businessman said, "and tell me what's wrong for me.""Oh, there's no need for me to examine you AGAIN," the doctor said. "Just continue taking the medicine I prescribed for you when you came to me last time."86. What happened to the businessman one day? A He failed in his business. B He fell ill and couldn't find a doctor.C He was asked to pay $500 for his illness.87. Was Dr Smith expensive? A Yes. He charged a lot for a patient's visits. B No. He charged little for a patient's visits.C Yes and no. It depended on who the patients were.88. What did the businessman decide to do? A He decided to go to another doctor.C He decided to ask Dr Smith to reduce the fee.D He decided to visit Dr Smith twice.89. What do you think of Dr Smith? B He was an experienced doctor.C He was a good doctor but charged far too much.D He cared nothing for his patients.90. Which of the following lessons does the story try to teach us? A Money is not everything.C No man is wise all the time.D Spend less but gain more.V.Translation (20 points, one item for 4 points)Directions: There are five sentences in this part.

新高考八省联考2025届高三模拟考试语文试题2(解析版)

新高考八省联考2025届高三模拟考试语文试题2(解析版)

新高考八省联考2025届高三模拟考试语文试题2一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,19分)阅读下面的文字,完成1~5小题。

材料一:文学主题与历史主题、时代主题紧密相连。

中华民族伟大复兴是当今中国的时代主题,也是新时代文学的主题。

心系民族复兴伟业,热忱描绘新时代新征程的恢宏气象,是当代作家的使命所在。

以脱贫攻坚为例,中国共产党团结带领中国人民打赢脱贫攻坚战,在中华大地上全面建成了小康社会,历史性地解决了绝对贫困问题,摆脱贫困的广袤乡土正朝着乡村振兴的目标迈进。

相应地,在文学界涌现出赵德发《经山海》、陈毅达《海边春秋》、王松《暖夏》、季栋梁《西海固笔记》等以脱贫攻坚为主题的优秀作品。

这些作品虽然题材各异,形式风格不同,但从中我们能看到因地制宜的脱贫实践,看到扶贫干部、乡村群众、创业青年、支教老师等人物故事,感受到苦干实干的奋斗精神。

与此相似,生态文明建设、中华优秀传统文化创造性转化创新性发展、构建人类命运共同体等新命题,也拓宽着我们的思想视野,给文学创作提供前所未有的广阔空间。

作家们瞄准这些命题,以文学的方式记录时代步伐,描绘发展画卷。

新时代文学主题更加鲜明,源于当代作家更加强烈的历史主动精神和更加自觉地深入生活、扎根人民,同时也离不开作家在文学创作上的锤炼打磨。

“登高使人心旷,临流使人意远。

”越来越多的作家意识到,只有深刻把握民族复兴的时代主题,以文学的方式感国运之变化、立时代之潮头、发时代之先声,不断锤炼文学深入时代、表现时代的能力水平,新时代文学才能真正做到与时代同频共振。

深刻把握民族复兴的时代主题,是当代作家贯穿创作始终的功课。

这不仅意味着作家要带着历史视野穿透现实,认识时代主题的独特性与丰富性,书写时代主题所带来的重大社会变革以及蕴含其中的中国精神;还意味着要对文学手法进行探索打磨,更独到地切入主题,更艺术性地呈现主题,将主题高度真正转化成艺术高度。

我们的现实生活中传统、现代因素相互交织,农业文明、工业文明、信息文明彼此并存,既不同于以往的历史,也不同于经典作家已有的文学叙述。
