限时训练(十六) 小说阅读 (时间:20分钟) 班级:姓名: 一、(2019,盐城节选)阅读下面的小说,回答问题。 芬芳的蜡梅花 秦湄毳 ①天空飘着雪花,和雪花一同落在我手中的还有朵朵芬芳的蜡梅花——几个学生随信寄来的,我不禁带着微笑想起那群学生…… ②秋风扫净落叶的时候,学校临时安排我接管初三的一个班,这个班里有几个出了名的“捣蛋鬼”。 ③一进教室,我就看见靠门的小书桌边缘刻着一个“恨”字——而且右边多了一点,我知道这是一群“恨错了”的孩子,我笑了,我微笑着说:“孩子们,我有一个难题,请帮助我解决。”他们停住了嚷嚷,睁大眼睛望着我,眼神很丰富:有吃惊,有冷漠,有怀疑,有猜测……这么多样的眼神一齐注视我,我也有些慌神,不由歪了一下身子,我掩饰地清着嗓子说,“我做教师有一个致命的弱点,那就是我的咽炎愈来愈严重了。我今年30岁,可我的声带却未老先衰,恐怕有300岁的年纪了。”听到这里他们中不少人笑了,有情不自禁笑的,也有故意大声呵呵的,但我发现他们的表情里没有恶意。我放心地笑了…… ④接下来的情形可想而知,他们卖力地献计献策,我一一点头说“试过了”。最后,他们有些泄气,有的已开始“脖子扭扭屁股扭扭”,我想我得实施我的“底牌”方案了,否则这只能是疲软无效的“情感搭讪”。突然,我听见小胖说,“我知道一个方法,就是用蜡梅花拌蜂蜜……”这就是我要等的那个孩子,他终于发话了,我早知道他是这个班的“七寸”。我说,“是吗?这个办法倒还没试过……”
⑤窗外,飘着雪花。我和小胖这些孩子的对话也像雪花一样落进彼此心里。显然,他们开始配合我、“帮助”我了。 ⑥其实,我只需要他们的配合,并不指望他们的“药方”。事实上,他们在卖力地“帮助”我,放弃了属于自己的玩乐时间,为我寻找新鲜的蜡梅花…… ⑦有一天,他们的“小神探”跑来给我说,“老师,小胖领着我们找到一片蜡梅树林,我们摘了一些在家晾着呢,等干了给你拿来。”我呆了,想着他们可别“毁林”啊。 ⑧我悄悄叫来小胖,谨慎地想着措辞,不想小胖挺“诡”,一听就明白了,大声大气地 说,“老师,那是一片没人管的废林子,正改建,快挖没了,再晚了就摘不到了。”我将信将疑拨通报社朋友的电话,他索性带我去实地考察,果然小胖的话属实。这是一片荒园,就“藏匿”在学校附近,很像鲁迅笔下的“百草园”,本真的自然景色让我很动心,思忖着:哪天带学生来游一回。 ⑨一个漫天飞雪的周末,我经过教室的时候,发现小胖正在门口小书桌上用橡皮泥仔细地抹平那个“恨”字,然后在上面贴了一张心形贴纸,用力地按了按,并端端正正地写下一个“爱”字。我激动了,在班里宣布,“放学后踏雪访梅去!”小胖喊,“我带路给老师摘蜡梅花去!” ⑩雪花、梅花、孩子们的笑脸、欢声,浩浩荡荡地欢腾着那片荒地,缕缕的芳香缠绕着我的眼耳鼻喉,我快乐着孩子们的快乐。那一刻,在我眼中,这群孩子就是一朵朵美丽的蜡梅花——你闻不到他们的芳香,是因为你还没有走进他们的心里…… 花香太浓了,弥漫在眼里,我禁不住落泪了,哦,这芬芳的花儿,芬芳的孩子! 今冬,又飘雪了。看着手中他们寄来的小小蜡梅花,我分明闻到他们心灵里散发的香。我想说,此刻,我陶醉。 (选自《散文·海外版》2019年第4期,有删改) 1.本文回忆了“我”与学生交往的几个片段,请在横线上补全相关内容。

However, they can also cause problems and unhealthy addictions. This is most clearly seen in the example of South Korea. This country has the world’s highest percentag e of high – speed Internet services. It has also a high number of game players who are addicted to online games. In 2004, a young man died after playing online games almost nonstop for 86 hours. A 12 – year – old boy stole $ 16,000 from his father to continue online games which he could not get away from. Such problems are spreading to other parts of Asia as well. In 2005, it was reported that about 80 percent of China’s 13.8 million online game players were under 25. And many of these were said to be addicted. Such numbers point toward a growing problem among Chinese youth. Dr. Sue – Huei Chen, a psychologist (心理学家), discovered some signs of at – risk people. Such people often go online to escape from their problems. And they usually have no friendship or good social skills. They feel the need to spend more and more time online, so they may be absent from school or family. And they become upset if anyone tries to limit their online game playing. 56．The passage is mainly about .

阅读限时训练（四） A On August 16, 1977, Elvis Presley saved me. The previous afternoon, I played with my six-year-old peers in Heather Peters’ backyard. I was enjoying my cake, when Heather asked me where my sleeping bag was. Only then did I know this party was a sleepover. The word “sleep-over” to a six-year-old bed-wetter is like what “cancer” means to an adult. But what if I told them I was a bed-wetter? At least with cancer, people gather at your bedside instead of running from it. I thought of a way to escape. I would explain that I needed my mother's permission to spend the nights. But as I called my Mom, Heather stood beside me to listen. She granted permission! Then I would be sleeping in the same living room as the other girls. I didn't bring my own pajamas (睡衣)，so Mrs. Peters offered me H eather's pajamas. As the other girls drifted into their sweet dreams, I tried to stay awake. “Do I need to go again? I'll stay up to go one more time.” Of course, I finally fell asleep. The next morning, I was the first to wake up. I was warm! I lay in panic for what seemed like hours before the other girls started to wake up. I did the only thing I could do --- I pretended that the bed-wetting didn't happen. I got up, took off Heather's pajamas and changed into my clothes like the other girls. Mrs. Peters walked into the room, and before she could say anything, she stepped right onto the pile of my wet pajamas. My heart stopped as I watched her face burn red. “WHO DID THIS?” She screamed, with a look so frightening. Should I answer? And that was when it happened — Mr. Peters came in and grabbed his wife, ‘‘Elvis Presley died!” The news of the King's death overtook Mrs. Peters, and I, was spared. I got home without the other girls knowing what had happened. 21. The author had to spend the night at Peters' because _____. A. she enjoyed her cake there B. it was a routine of the party C. her mother allowed her to do so D. the famous singer Elvis Presley died that night 22. Mrs. Peters got angry because _____. A. her husband was rude to her B. Elvis Presley passed away C. she found the wet pajamas D. all the girls slept at her house 23. From the story, we know Mrs. Peters was _____. A. a bad-tempered woman B. a fan of Elvis Presley C. a woman for perfection D. a woman who hated to wash pajamas 24. The passage is mainly about _____. A. an unfriendly hostess B. a fan-purchasing experience C. the shocking death of a famous singer D. an embarrassing childhood incident B Have you ever lost your car on a parking lot? You don’t have a clue where your car is after shopping. Then you start walking around clicking on your car keys so the alarm goes off. It can be annoying, especially on a hot sunny day. No, you needn’t install(安装) an expensive GPS system to keep track of your car. That’s too expensive. You would need to pay a monthly fee to use it. But is there a way to track your vehicle without spending a fortune? Yes, now there is! A California-based company has created a tiny device that works with your smartphone, which could be exactly what you’re looking for! What is it? It’s called TrackR. It is a state-of-the-art tracking device the size of a coin. It’s changing the way we keep track of the important things in our lives. How does it work? It’s easy! Install the free TrackR app on your smartphone, connect the app to your device and you’re ready to go! Simply attach TrackR to whatever you want to keep an eye on. The entire process of setting it up only takes 5 minutes or less. You can attach it to your keys, briefcase, wallet, your latest tech gadgets and anything else you don’t want to lose. Then use the TrackR app to locate your missing item in seconds. If you forget where you have parked your car, pull out your smartphone and open the TrackR app. Tap on the “find device” button on the screen and the app will tell you the exact spot of the last known location of the TrackR. What else can I do with TrackR? The device is small and unnoticeable enough that you can attach it to your pet. Put it on their collar, and the issue of searching for them when they run away to nearby places will be over! You’ll never waste a minute searching the whole house for it. TrackR even comes with a double-sided glue so you can stick it to your laptop or under your bike seat. Track down and punish the thieves who steal your expensive things! How much does it cost? You’re probably thinking that this device is very expensive. False! TrackR only costs $29! That’s a small price to pay for peace of mind, isn’t it? Where can I buy one? You can buy it directly from the company’s website by clicking here https://buy.thetrackr.co/gu/special-offers/15/ . 25. From the passage, we learn that TrackR can ______. A. take good care of your pets at home B. help you locate your important things C. work better after you pay monthly fee D. track your wallet through GPS system 26. This passage is mainly developed by ______. A. providing statistics B. giving examples C. answering questions D. making comparisons 27. Where is this passage most likely taken from? A. A website. B. A journal. C. A personal blog. D. A research report. C Our non-profit organization had just received a large donation of clothing.

适合年级：高二~高三 建议用时：28—32分钟 A Yao Ming, the first major Chinese star to break into the NBA, has decided to retire after nine seasons with the Rockets, according to league(NBA联盟) sources，July 9th，2011. The 30-year-old center played just five games over the past two seasons and has decided that he is unable to make a complete recovery from the injury in his left ankle. At 7-foot-6, Yao entered the league in 2002 as the largest symbol of the NBA's growing expansion around the world and particularly in Asia. Yao was an eight-time NBA All-Star and in five seasons he was voted onto the league's second or third All-NBA team. He averaged 19.1 points and 9.3 rebounds and 1.9 blocked shots in his career. He arrived in Houston in 2002 as strong as the Great Wall of China, yet over the course of his NBA career Yao's image became increasingly fragile(脆弱). After missing just two games due to injury in his first three years in the league, he was sidelined（坐在场边板凳上）for 250 over the past six seasons. Yao had spent months trying to cure his ankle for one more chance at playing. He has said his desire was to remain in Houston to play for the Rockets. However, he did not want to destroy his health for life after playing. Yao's parents were concerned enough about him that they did not want him to attempt a return to the NBA after the broken bone in his foot that was suffered in the playoffs（季后赛）of May 2009. Following the birth of his daughter, Yao said: "I can only try so many times. I want to be able to run around and play with my child, not always wear a cast（石膏）and use these crutches." At the press conference for his retiring, he said：“I have once said, when I retire from my professional career, I hope that it is a comma, not a period. Today, that day has finally arrived, but I am not leaving the sport of basketball that I love. My life will continue. I am still Yao Ming and there are still many things that I wish to accomplish. The day of drawing a period is still far far away.” 1. Which of the following statements is TURE? A. Yao Ming played for the Rockets in the NBA. B. Yao Ming played in the NBA. for 10 years. C. Yao Ming is the first Chinese player to break into the NBA. D. Yao Ming will go on playing for the Rockets in the NBA. 2. Why did Yao Ming retire from the NBA? A. Because he is too old to continue to play in the NBA. B. Because he has serious injuries. C. Because his parents are against his NBA career. D. Because of the birth of his daughter. 3. Yao Ming could play almost all games without being sidelined in seasons. A. 1 B.3 C.6 D. 9 4. According to the last paragraph, what is the meaning of the underlined word “crutches”?

加强英语阅读限时训练提高学生做题效率
加强英语阅读限时训练提高学生做题效率 湖北省巴东县第二高级中学沈玉邮政编码：444324 一．限时训练的重要性 许多学生平时在做阅读题时准确性很高，但做题速度较慢。在较正规的考试中，这些学生往往得不了高分，成绩不是很理想。究其原因就是英语教学中限时训练不到位，导致学生做题速度慢，考试时间不够用。在目前的英语高考中，英语试题题量大，所涉及的知识面宽，如果平时限时训练不到位，学生在考场上容易产生紧张情绪，时间利用会不合理，从而成绩不理想。因此，有针对性地训练考生驾驭时间的能力，提升考生在考试中的夺分能力尤显重要，英语教师在教学过程中要有目的地加强限时训练。 二．限时训练的方法 （一）让学生认识到限时训练的重要性、培养学生限时训练的意识和习惯教学是一项双边活动，需要教师和学生的紧密配合。只有首先让学生意识到了在规定时间内保质保量地完成任务的重要性，并配合老师积极主动地加以训练，才能使限时训练事半功倍。在这个过程中切忌强迫学生，而要潜移默化、循序渐进。 （二）限时训练要与讲解解题方法、进行能力提升同时进行 限时训练要在给学生讲解解题方法、解题技巧的基础上进行，要让学生不是一味为了限时，而要在运用要各种解题技巧、确保准确率的基础上限时，限时训练才有意义。同时，只有让学生理解、掌握了必要的解题技巧、提升了做题能力，学生才有信心进行限时训练。 （三）合理安排限时训练的内容 1、限时训练的内容应由浅入深、由易到难、循序渐进 英语老师在安排训练内容时必须首先考虑到由浅入深、循序渐进的原则，切不可一开始就上难度、高要求，让学生一步一个脚印，逐步提升。 2.训练内容要体裁丰富、贴近生活、紧扣高考 教师要精选阅读、完形填空内容，力求做到体裁丰富、贴近生活、时代感强并紧扣高考。学生通过这些内容的限时训练，能够开阔视野、丰富知识、提高学习英语的积极性。 3.重视文章篇章结构、语境及语义的理解 对文章的语篇结构分析，有助于学生对文章的整体把握，使学生读文章时思维清晰、阅读效率高。强调语境的作用，引导学生巧用上下文分析、解决问题，（四）合理安排限时训练的时间，课堂限时训练与课外限时训练有机结合教师要合理安排限时训练的时间和频率，限时训练要天天进行，让其成为学生英语学习的常规，养成良好的英语学习、训练习惯。要把课堂限时训练与课外限时训练有机结合，在课堂时间较充裕的时候，让学生在有限的时间内完成规定的阅读或完形填空题内容，老师对学生的限时训练情况有充分的了解，对学生的良好表现要给予充分的肯定，对不足之处要及时分析并提出解决方案。在课堂时间有限的时候，要安排学生在课外抽出时间进行训练并对训练情况进行抽查，这样有利于培养学生自觉学习、训练的良好习惯。但在限时训练中不能过分挤占学生的课外时间。 三．如何保证限时英语阅读训练富有成效
