Then he began to breathe and move his arms. At first, I thought he would be a fine-looking man. He had yellow skin, black hair and very white teeth. Unluckily, his eyes were watery, and his lips were thin and colorless. I soon realized that there was nothing beautiful about him. I ran out of the room, disgusted (恶心) by the creature I had created. I tried to sleep, but for hours I could not. Then, when I did get to sleep, I had bad dreams. When Iawoke the next morning, I did not want to return to my laboratory and the monster I had created.I went for a long walkuntil I came to an inn. There, to my pleasure and surprise, I found my friend, Henry Clerval. “Tell me about my family,”I asked him. “And Elizabeth, How is she?”“They are all well, Frankenstein,” he said. “But you do not look well, my friend. Your eyes look as if you have not slept for many weeks.”I knew this was true. “I have been so busy,” I explained, “that I have been working without rest.” Henry walked back with me to my department. I did not want him to, but I could not stop him. I was afraid that the creature I had left there might be alive and walking about. When we reached my apartment, I asked Henry to wait outside for a few minutes. I did not explain why. I slowly opened the door and entered the room. To my surprise, it was empty. The creature had gone. I was so overcome by the feeling that I fainted. I was ill for many months.During my illness, Henry was my only nurse. He heard me talking in my sleep about a monster. At first, he thought I was just having a bad dream, but then he realized that something very bad happened in my life. At last, I began to get better.1．What is this passage probably taken from?A．A news report. B．A science fiction. C．A travel guide. D．a history book.2．What’s the main idea o f the first paragraph?A．The birth of the creature. B．The personalities of the creature.C．The happy feeling of creating life. D．The spirit of the creature.3．What does the underlined word “fainted” in Paragraph 4 probably mean?A．broke down B．cheered C．lost senses D．went wrongB14、Twinkle, Twinkle Little Star is a lovely song for children, but it has two misunderstandings (误解). First, stars aren’t little. Some may be Earth-sized, but most are bigger than Jupiter, the largest planet in the solar system (太阳系). Second, they don’t twinkle; they shine. And the brightness and color of the light from each star provide information about its temperature, size and even its age. viewing the stars from Earth is a bit like looking at them through a water filter (过滤器) because the air is thick compared to the emptiness of space. What is more, air is always moving, so starlight appears to be moving, too. The air also makes stars appear dimmer (暗淡的) than they would be if we could see them from space.If you stop and look at the sky carefully on a dark and moonless night, it’s easy to find color differences among stars. The color of a star is a signal of its surface temperature. The hottest stars are blue, and the next hottest are white. Yellow stars like the sun are next, while red stars are the coolest of the visible (可见的) stars. Many red stars are so dim that people can’t see them at all, and some stars hardly send out any light at all. One reason that stars different in brightness is that hotter stars produce more energy than cooler ones, but another important reason is that some are much bigger than others.Some stars appear brighter to humans simply because they’re closer. Astronomers rank (排列) the brightness of stars which are seen from Earth by giving them a name known as magnitude (光度) ---the smaller the magnitude, the brighter the object. They have also designed a number that ranks stars according to how bright they are when compared to each other. With a magnitude of minus 26.7, the sun is the brightest object in the sky.1．From the song quite familiar to children, the writer wants to prove that .A．most stars are smaller than JupiterB．Jupiter is bigger and brighter than EarthC．stars are very large and always shine brightlyD．starlight’s brightness and color are the signs of its temperatu re2．Magnitude is designed to see .A．how far a star is from EarthB．how bright a star is compared to other starsC．how far a star is from other starsD．how bright a star is seen from Earth3．Which is the best title of this passage?A．What do stars look like?B．Which song do children like best?C．How to view the stars from Earth?D．Why are many stars so dim at night?C15、Welcome to the Electronic Village to find new ways of language teaching and learning.1．Nearpod can be used to ________.A．offer grammar testsB．teach listening on-lineC．help vocabulary learningD．gain fluency in speaking2．If you want to improve your speaking skills, you can go to ________. A．Room 602 B．Room 502C．Room 601 D．Room 5013．Which of the following can help students learn how to study on-line? A．Prezi. B．Kahoot. C．Nearpod.

He then hid himself and watched to see if anyone would move the boulder out of the way. Some of the king’s wealthiest business men an d courtiers (朝臣）came by and simply walked around it.Many people even loudly blamed the king for not keeping the roads clear, but none of them did anything about getting the stone out of the way. They just complained and went away. A peasant (农民）then came along carrying a large bag of vegetables. Upon getting closer to the boulder, the peasant laid down his burden and tried to push the stone out of the road. After trying and pushing for a long time, he finally succeeded.After the peasant went back to pick up his vegetables, he noticed a purse lying in the road where the boulder had been. In the purse there were many gold coins and a note from the king explaining that the gold was for the person who removed the boulder from the roadway. If you were on the way, what would you do? Complain it or move it away? Every difficulty we come across in life gives us an opportunity to improve our situations, and while the lazy people complain, the others are creating opportunities through their kind hearts, generosity (慷慨大方)and willingness to get things done.1．Why did the king put such a boulder on a roadway?A．In order to make the roadway special.B．In order to stop someone who are lazy from walking to his country.C．To see if anyone would move the boulder out of the way.2．What did many people do with the big stone on the way?A．They just complained and didn’t do anything about it.B．Many of them tried to move it but failed.C．Many thought it was the king’s duty to move it away from the road.3．The peasant got the stone out of the way successfully by ________.A．pushing it without any hard workB．trying and pushing hardC．using his large bag of vegetables4．Which of the following is TRUE according to the passage?A．Many people didn't find the stone on the way.B．The peasant got a lot of money after moving away the stone.C．The king wasn’t glad to see the peasant removed the boulder from the roadway.5．We can infer (推断）from the passage that ________.A．all things are difficult before they are easyB．it is never too late to mendC．opportunities are for those who are willing to do something with kindness and generosityF18、Making friends might seem to come easy for some persons, but it’s maybe very hard for most persons. No matter how many friends you might already have, it is always a good idea to make new friends.Being shy keeps a lot of people from making friends. Also, making friends might need a person to step outside of their comfortable places, which are hard for a lot of people, whether they are shy or not. However, overcoming the shyness to step out of your box is an important step in making friends.There are lots of ways to meet new friends. First of all, remember that a good friendship is based on interests, so if you are ready to make friends, start to join clubs or go places where you have interest. For instance, if you like to play sports, join a sports team or after school sports club. If you have interests in music or writing, join clubs or organizations that you are interested in. When you see someone in a place like that, and you think that they look nice, it is always a good idea to go up to them and introduce yourself and ask interesting questions so that you can start a conversation. Don'tput too much pressure on yourself, and remember that friendships don't always happen quickly.Some friendships happen right away, and you'll be able to tell if someone will be a great friend right after you meet them. Some friendships take a long time to develop. Anyway, the friends that you meet are going to be worth it. If a friendship develops quickly, it doesn't mean that it is extra valuable, and if a friendship takes a long time to develop, it doesn't mean that it isn't worth it because it's too hard.Making friends might be a bit difficult for you, and the friends you will make may not look anything like you. However, even though it might be scary to start conversations, you are worth doing it. All friendships start with a single hello. 1．From the passage, it’s ______ to make friends for most people.A．easy B．convenientC．impossible D．difficult2．If you want to make friends, you should ______.A．ask your parents for helpB．go out of your own boxC．obey others’ requestsD．talk more with shy persons3．What are the friends like after you have them?A．They’ll do the same things as you.B．They’ll go to the same places.C．They may not look anything like you.D．They may give all you need4．According to this passage, we know ______.A．if we have many friends, it isn’t necessary to make new friendsB．stepping out of the comfortable places is easy for outgoing personsC．friendships always happen quickly if you introduce yourselfD．the same interests among persons may make you get the friendship5．What does the writer want to tell us?A．How can we make friends?B．What is the friendship?C．Who can we make friends with?D．When do friendships happen?Ⅴ.书面表达19、当前，我市各学校正在开展“好书伴我成长”活动。
二十三中学习培训总结
武威第二十三中学培训学习总结沈海山武威第二十三中学之行，本人感触良多，要提高学生综合素质，要打造高效课堂，要提高教学质量，就应该把课堂真正还给学生，让学生成为课堂的主人,尤其在数学教学中,应该让学生在课堂上探索,在课堂上训练,在课堂上提高.课堂是我们教师掌控的主阵地。
课堂教学中原有的陈旧教学模式、落后教学方法，严重阻碍学生思维的开发，严重阻碍学生创新精神的培养。
长期以来,我们虽然认识到了我们在教学中存在这样的错误,但缺乏行之有效的改进办法。
这次武威第二十三中学之行，我们发现了通过以下改变可以解决我们的实际问题。
一．教学中完成三个转变1.进一步转变信任思想。
教师在课堂教学实践中，要充分相信学生，相信学生能行很棒，改变以往教师一人唱独角戏的思想，不给学生任何机会。
2.进一步是转变主体思想。
教师在课堂教学中，要充分发挥学生是主体的作用，教师围绕学生转，改变以往教师满堂灌,一节课下来学生的一切权力被剥夺了。
武威第二十三中教师在数学中教学是通过出示大量自学指导练习，让学生自学，探究。
个别知识点教师纠错释疑。
3.进一步是转变不开放思想。
教师在课堂教学中，要允许学生自由讨论，自由交流，发表不同意见，改变以往教师一味求标准答案，唯一答案，从而限制学生发散思维的培养。
从武威第二十三的课堂中，不难看出他们的学生千奇百怪，层出不穷，思维活跃，表达流畅。
二．改革两种传统的固有的模式。
一是座位编排模式。
在平时我们的班级管理中，教师都喜欢按横纵的一定顺序排座，武威第二十三中学学生的座位是分组坐，好学生和学困生搭对坐，大大方便了学生的交流机会，大大扩展了学生的讨论空间。
二是讲课模式。
以往大多数老师都采用老师讲，学生听的，一节课只听见老师的声音，学生都哑口无声。
从武威第二十三中学课堂中，不难可看出教师讲解不易找到，即使看见老师在讲，也只不过讲基本概念、定义，时间不会很多。
他们在教学过程中重视课堂练习的设计,教学时通过有层次多角度的题组设计,在解题时逐步引导学生解决问题,同时教师在纠错的过程中完成知识点的讲解和学习.在整个课堂中以练习为主线,在练习中解决问题,在练习中学习新知识,在练习中提高解题能力,在练习中完成教学过程。
