I had supposed that selling things on the Internet was so easy that even beginners could start making money on the very 17 day. I spent most of my time advertising rather than learning 18 to advertise. However, half a year’s hard work led to no money at all.

I began to 21 that the Internet sale is a job like any other job and I would have to take it 22 . I kept trying to cheer myself up, which I thought was the key to success in sales. I insisted on the excellent Internet marketing and then good 23 came. My dabbling became a hobby, and then passion (热情). Later passion 24 my business. I have really become a millionaire within a year.
The more I learn, the more I realize I need to learn more. I’ve made a lot of mistakes, but I know that every mistake is just one more step forward, as a song tells us “you’ve got to lose to know how to win.”

When the two brothers were old enough to marry, their father was not happy because their family wasn’t so rich that the brothers often argued with each other about some small interest. He really didn’t know how they would fight when they broke up the family and lived apart (分开).
One day, their father was sick, lying in bed and staring(凝视) at something, when the elder son came over to wish him good health. His father said, “Ask your brother to come here, and I have something to say.”
The younger brother arrived. Their father sat up and said, “I don’t know how the disease hit. I’m feeling terribly unwell.” The brothers persuaded (劝说) their father not to worry about it, but he shook his head, “In fact, I don’t worry about the disease because I can manage it, but if you are in disorder with each other in the future, it will be our family’s disease and no one can deal with it.”
The brothers felt ashamed.
The father got out of the bed, pointed to some chickens in the yard and said, “Look at them sitting there in peace with each other, isn’t it good?” then their father brought out a bowl of corns, went quietly behind the house and spread most of them on the ground. Then he went back to the yard with only a few corns left and flung(挥动) at the chickens. As soon as they saw the corns, the chicken jumped up, waved their wings and fought for it. The peaceful world was now filled with smoke of gunpowder for some corns.
The brothers smiled and understood what their father was driving at.
Their father added, “Both of you saw more corns are behind the house…”

Many people believe the glare（炫目的光）from snow causes snow-blindness. Yet, with dark glasses or not, they may have headaches and watering eyes, and even snow-blindness after several hours of snow light.
The United States army has now found out that glare from snow does not cause snow-blindness in army in a snow-covered country. Rather, a man’s eyes often find nothing to focus on(聚集) in a broad space of snow-covered area. So his long fixed look continually moves and jumps backward and forward over the whole landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles(肌肉) ache. As tears continued increasing, they make eyes difficult to see dearly, and the result is total, even though for a short time, snow-blindness.
Experiments led the Army to a simple method of overcoming(克服) this problem. Scouts（侦察兵）ahead of the army are trained to shake snow from evergreen bushes, creating a line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark - colored objects ahead on which they can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow-blanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow-blind or lost. In this way the problem
of crossing a continuous white land is overcome.
34. What is the first paragraph mainly about?
A. The whiteness from snow.
B. Snow light and snow blindness.
C. The need for dark glasses.
D. Headaches and watering eyes.
35. Snow-blindness can be avoided ________.
A．by moving the eyeballs with more and more tears
B．by walking ahead and keeping looking around
C．by making up for the discomfort of one’s eyes
D．by providing the eyes with something to focus on
36. What is the best title for this passage?
A. Snow-blindness: what it is and whom it influence
B. Snow-blindness: what it is and how nature helps
C. Snow-blindness: how it forms and how to solve it
D. Snow-blindness: how it forms and whom it hurts
37. Which of the following can be inferred from the passage?
A. Solving the problem of snow-blindness is important in army.
B. Snow-blindness was once a big problem but could be cured easily.
C. The glare from snow is considered as the main cause of snow-blindness.
D. Armies around the world pay attention to the problems of snow-blindness.

六、任务型阅读
Some people believe that greed(贪婪) and selfishness has become the main theme of modern society, and we should return to the old traditions of family and community in order to have a
In this fast-paced(快节奏的) world, many values are experiencing great changes. While people traditionally caring, sharing and generosity the most important things in life and work, modern people seem to be more self-centered.
Modern people act selfishly to survive the highly competitive world. To survive, you have to fight with whatever ways you can think of. Obviously greed and selfishness go perfectly well with such ideas. In a company, workers do everything they can to get better pay and higher position, even if it means their workmates will lose a lot because of this. They are not born cold-blooded; it is just that people are pressured to act in a certain way because of outside influences.
To be honest, it is hard to say that modern society is built on greed and selfishness, both of which are not newly invented vocabulary. In ancient times people also did greedy and selfish things though such behaviors were more seriously punished then. But we can’t be blind to the fact that people in the past faced less pressure compared with the modern environment.
Are we happier to share with others and be generous to them? There is no fixed answer either. Some people take great pleasure helping and giving to others while others feel happy doing the opposite. But I personally think that people should not be too selfish. Caring for others can actually encourage the development of a win-win relationship.

无锡13所初中排名 1、大桥中学 优势： 1、大桥中学学风较好，孩子们相互竞争，有良好的学风。 2、大桥中学教学质量一直比较排名靠前。 3、大桥中学有直升名额，借读生成绩比较好，也可直升。 4、大桥中学借读生，可以通过自主招生和计划外考取其他四星级高中 劣势： 1、大桥中学尖子生云集，竞争激烈，孩子学习压力大。 2、大桥实验学校学生数量相对较小，中考名额分配较小，借读更不享有分配名额。 3、大桥实验学校正常学费每学期6000元左右，费用偏高，借读生还要在学籍所在学校缴纳一定费用，花费比较大。 2、辅仁中学 优势： 1、辅仁初中是无锡一流初中。最近几年的成绩不错，2011年中考成绩超过外国语。 2、辅仁初中年级排名前五十，一般都能得到辅仁高中的签约。一部分能直接进入辅仁高中的双语班A班。据统计，辅仁初中65%的学生能进入辅仁高中。 3、无锡市民办辅仁中学是一所管理满严格的学校,教学水平很好。 劣势： 1、辅仁中学与辅仁高中之间没有直接关系，辅仁高中是公办的，辅仁初中是民办的。 2、辅仁中学是平行分班。 3、公办快班和辅仁差距不大，择校要考虑距离远近的问题。 4、交通不是很方便。 5、费用较高。 3.天一中学 优势： 1、学籍 学籍是选择公办中学的一个重要因素。天一实验学校本区内学校集中转移学籍相对容易，跨区则需要自己解决学籍问题。 2、分配名额 名额多 天一实验班级前十能获得分配名额，天一实验学校相比于省锡中实验学校，分配名额较多。省锡中五四班由于无法解决学籍问题，会占掉部分省锡中实验学校的分配名额。
