When I became a junior, I decided to take Latin at school. I was so 21 about taking that class, and I was fully expecting to be able to 22 every word I’d ever come across once I learned Latin.
But Latin class was so 23 . Each day, the teacher Mr. Keady would ask us to open our 24 and recite aloud the various Latin forms of words. This became the 25
every day. That was until my hand 26 one afternoon when we were asked yet again to open our books.
When Mr. Keady asked what was wrong, I 27 why I thought that his class was dull, how I had expected more, and that his method of teaching was 28 . When I finished speaking, I 29 Mr. Keady to angrily send me to the head teacher.
But instead, he sat at his desk quietly, looking defeated and tired. After several moments of 30 , Mr. Keady spoke. He quietly and firmly said that he would 31 carefully about what I’d said. And that was it.
In the following weeks, Latin class didn’t become the excitin g learning environment I 32 it would, but Mr. Keady did try harder. He brought in some new worksheets and 33 to involve us students more in his classes.
Maybe some people would 34 what I did, but even so many years later, I feel bad about it.
If I saw him now, I’d tell him how I 35 what I’d done that day in class, and that I was disrespectful. And at the same time, I’d also tell him that he taught me a wonderful 36 that day. Following my 37 words, he showed me that being 38 doesn’t mean you have to give away your dignity.
Indeed, Mr Keady’s 39 proved that no matter how hurt you feel, no one - no one - can 40 your dignity.

I once heard this tale in India, where it is told as if true — though any naturalist would know it couldn't be. The country is India. A colonial (殖民地的) official and his wife are giving a large dinner party. They are seated with their guests — army officers and their wives, and a visiting American naturalist.
A spirited discussion springs up between a young girl who says women have long outgrown the jumping-on-a-chair-at-the-sight-of-a-mouse era and an army officer who says they haven’t. “A woman’s reaction in any crisis," the officer says, “is to scream. And while a man may feel like i t, he has that ounce more of control than a woman has. ”
The American scientist does not join in the argument but sits and watches the faces of the other guests. As he stares, he sees a slight strange expression come over the face of the hostess. She gestures to the servant standing behind her chair and whispers to him. The servant's eyes widen. He turns quickly and leaves the room. Of the guests, none except the American notices this or sees the servant place a bowl of milk on the balcony just outside the open glass doors.
The American understands. In India, milk in a bowl means only one thing: bait (诱饵) for a snake. He realizes there must be a cobra in the room. The American’s eyes move across the room but he sees nothing. He realizes the snake can only be in one place — under the table.
His first reaction is to jump back and warn the others. But he knows any sudden movement will frighten the cobra into striking. He speaks quickly, the tone of his voice so arresting that it quietens everyone. “I want to kno w just what control everyone at this table has. I will count three hundred — that's five minutes —and not one of you is to move a muscle. Now, ready!”
The 20 people sit like stone images while he counts. He is saying “... two hundred and eighty… ” when, o ut of the corner of his eye, he sees the snake emerge and make for the bowl of milk. Four or five screams ring out as he jumps to slam the balcony doors.
“There is your proof!" the host exclaims. “A man has just shown us perfect self-control. ”
“Just a minute," the American says, turning to his hostess, “How did you know that cobra was in the room?"
With a faint smile coming across her face she replies: "Because it was lying across my foot. ”

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)
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. As three of us walked home for dinner, we saw a woman begging by the bridge. She was old and had no legs. She shivered in her thin

高中英语语言运用限时训练（三） （35分钟） 第一节完形填空 As a child, I had library phobia (恐惧症). I associated going to the library with doing research for a school project. I regarded reading as work, so going to the library for fun was out of my realm (范围) of 1 . Hard as they tried, my parents could not get me 2 reading. They purchased a few of the Hardy Boys books. The books collected dust. The closest I came to 3 to read was “The Big Green Book” by Robert Graves. Its lead character, a boy of about 8, discovered a book of magic spells. I was 4 by it. Spells were not in the book, but I drew an imaginary magic circle in my bedroom, stood inside the circle and 5 my own spell. I never became invisible (看不见的), which was my 6 . This was my favorite book. I read it again and again. Certainly there was no 7 to go to the library. Eventually, I started reading novels in my 20s. To 8 going to the library, I joined the various 9 clubs. I didn’t mind having to buy a book a month as long as I didn’t have to go to the library. My library phobia was 10 23 years ago when my family moved to Long Island. The East Meadow Library became a(n) 11 destination for my family. My children were 12 to books through the children’s section wi th free programs that even I enjoyed. My children made 13 , and I made friends with the parents.

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
