I wished I had known earlier the fact that I was a low achiever because there was a reason beyond my control. Then I 21 have worked so hard in my late twenties and early thirties. But I just didn’t 22 that. I was writing and writing. I was working for no other reason than to hear people praise me.
Most people who 23 university read at least twice as fast as I do. I can never tell my left 24 my right. I avoid dialing a telephone if I can help it, because I sometimes have to try three times before getting the number 25 . I hear that recording “The number you have reached is not 26 ” more than any man on earth.
Despite my 27 I view my dyslexia(difficulty in reading) as a gift, not a curse(诅咒). Many dyslexics are good at right brain, namely abstract thought ,and that is 28 my king of creative writing is. I’m starting with 29 and coming up with something that didn’t exist before. That’s my strong point.
I 30 my career to Ralph, Salisbury, my writing instructor at the university of Oregon, who looked past my misspellings and gave me 31 and hope. I just carried on and never looked 32 . I’m also very“visual”(视觉的).This means nothing in school, but when I write books or scripts, I’m seeing everything in my imagination. I write 33 . I go like the wind and can 34 up to 15 pages a day. Writing is not the 35 .
I have no problem downloading; it is inputting 36 things get messed up.
The real 37 I have for dyslexics is not that they have to 38 with messy input, but that they will quit on themselves before they finish school. Parents have to create victories whenever they can, 39 it is music, sports or the arts. You want your dyslexic child to be able to say, “Yeah, reading
is 40 . But I have these other things I can do.”

Instead she found ways of punishment that left me a more lasting memory. One of the most memorable of these occasions occurred when I was four. That day mother picked me up early from daycare because we were going to Sears&Roebuck to pay on a Christmas Layaway. I was excited by the lights and decorations, and as we walked through the toy section on the way to the Layaway Department, I saw a toy I had to have. It was a white and red telephone whose bells rang as it was pulled along on a string. Looking lovingly up at my mother I ask ed, “Mama, can I have that telephone?” She replied, "Baby, not now, but if you are a good girl maybe Santa will bring it to you. " "But Mama, I want that telephone right now. " Her eyes narrowed and her hand tightened on mine. "Becky, you can’t have that telephone today, but if you misbehave you can have a spanking. " By now we were standing in the long Holiday line in the Layaway Department, and I figure it was now or never. I lay down on the ground and began screaming, "I want that telephone, " over and over again. Weary Christmas shoppers looked as my mother calmly said, "Becky, you better get up by the count of three or else. One…Two…Three. " Nothing. I was still in full tantrum. So then she lay down beside me on the floor, and began kicking and screaming, "I want a new car, I want a new house, I want some jewelry, I want…" Shocked, I stood up. "Mama, stop. Mama get up, " I tearfully requested. She stood, and brushed herself off. At first stunned, the others waiting in line began to clap, and before I knew it they were cheering and laughing and patting my mother on her back. She blushed and took a little bow and the next thirty minutes in line was pure misery for me as various parents leaving the Layaway Department, shake their heads at me and say with a smile, "Your mom got you good. I bet you’ll never try that again. " And I didn’t, because it left a lasting mental picture more effective then any physical mark. 21. From the second paragraph, we can know that . A. It was after Christmas B. I was very well-behaved C. I liked a red and blue telephone D. I was a primary school student 22. The underlined word “tantrum” can be replaced by . A. disappointment B. sadness C. bad temper D. excitement 23.Why did the mother scream together with her daughter? . A. She wanted to educate the girl B. She wanted to amuse others C. She wanted the girl to buy those things for her D. She wanted to embarrass the girl 24. What can be inferred from this passage? A. The mother has many fans on educating daughter. B. The mother hit the girl in the Department. C. The mother planned to buy the telephone when the girl first asked. D. The girl is still naughty after this experience. B Why are people interested in eating raw foods or whole foods ? One reason is that eating these types of food reduces the risk of acid accumulation (积累；堆积)in your body. Raw and whole foods are usually digested more than cooked and refined foods. When we cook foods, we destroy the natural enzymes(酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes , our bodies either digest the food improperly or allow too many nutrients to be absorbed into bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs. Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle.

(2)当电子枪射出的电子动能E k=50.0 eV时，改变电压U（V），测出电流I（A），得出下图所示的I—U图线，图线表明，当电压U为5.00 V、2.88 V、2.72 V、2.64 V时，电流出现峰值，定性分析论述I—U图线的物理意义. (3)根据上述实验结果求出氦原子三个激发态的能级E n（eV），设其基态E1=0. 试题5: 曾经流行过一种向自行车车头灯供电的小型交流发电机，图1为其结构示意图。图中N、S是一对固定的磁极，abcd为固定在转轴上的矩形线框，转轴过bc边中点、与ab边平行，它的一端有一半径r0＝1.0cm的摩擦小轮，小轮与自行车车轮的边缘相接触，如图2所示。当车轮转动时，因摩擦而带动小轮转动，从而使线框在磁极间转动。设线框由N＝800匝导线圈组成，每匝线圈的面积S＝20cm2，磁极间的磁场可视作匀强磁场，磁感强度B＝0.010T，自行车车轮的半径R1＝35cm，小齿轮的半径R2＝4.cm，大齿轮的半径R3＝10.0cm（见图 2）。现从静止开始使大齿轮加速转动，问大齿轮的角速度为多大才能使发电机输出电压的有效值U＝3.2V？（假定摩擦小轮与自行车轮之间无相对滑动） 2018—2019 学年上学期武汉二中期末考试高一英语试卷 试卷满分： 150分 第一部分：听力（共两节，满分30分） 做题时，先将答案划在试卷上。录音内容结束后，你将有两分钟的时间将试卷上的答案转涂到 答题卡上。 第一节（共5小题；每小题 1.5分，满分7.5分） 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项， 并标在试卷的相应位置。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。 每段对话仅读一遍。 1.What will the man buy for the woman?
