dual view angle device Due to the traditional imagining technology which the projection images of 3D-objects are perpendicular to the perspective direction, the final image is the result of all objects superposed on the light path of imagining. Therefore, to the parcels with intentionally hidden dangerous goods or complex parcels, single view system screening efficiency is relatively low and the correct detection rate is also affected.

Therefore, to the parcels with intentionally hidden dangerous goods or complex parcels, single view system screening efficiency is relatively low and the correct detection rate is also affected. We can observe the knife does not look obvious in view-angle-1 in the following picture when the knife and gun are positioned in X-ray inspection system at a certain angle. To single-view device, usually, the suspicious objects are needed to be re-scanned at another angle; however, due to the dual-view devices provided another angle of view (angle 0), the existence of the knife and its exact position both can be certainly identified, which improves the actual passing through rate. The box of 24 cans liquid, in both horizontal and vertical directions of each row was set with only one empty bottle in the array. After scanning, we can`t find any clue from view angle 0, while we can obviously find the problem from the view angle 1. Similarly, if there are some dangerous goods are hidden in those empty bottles, compared with the traditional dual channel single view device, dual channel dual view devices will give its full play of advantages.

father and son-1 I have read a sentence in a book by a Chinese writer. The first half of life of a man is the shadow of his father, however, in the latter half of life, his father becomes his shadow. (Due to the limitation of my English ability, I may made a lot of mistakes and bad English in this essay, you can change the sentence for making it more logical, I am going to post it here after every time revising until it sounds very smooth ). That is proved by my experience. My grandfather told me that, father is a superman at your five years old. when u grown-up a little, then father is a powerful man. And in your teen age, he seems not as powerful as before. Since you totally grown up, you will find out father is just a common people. I could not agree it anymore because I did experience it myself. When I was a 5-years old boy, he could do everything in my eyes, he can buy whatever he wants. he could beat me, if I refused to follow his command. And he even can fix every broken thing in this world, many friends and neighbors came to ask him for helping with fixing things. It was my dream at that age, to be a powerful man like him. Several years later, I found that not very broken thing can be fixed well by my father, such as the virus computer. However, he still was the smartest person that I had known. Because he always knew what was the right decision for every time. However, everything is changing in this world, not to mention my thoughts about my father. During my teen years, I thought that he was right most of the time, but obviously not for every time. Since I wanted to study computer science, however, my father said no and he had another thought. Although it caused some arguments between us during that time and I finally gave up, now it no longer bothers me. Now, I can work to support my life and I am thoroughly independent from my father. I also have my own family include a naughty son. I guess I am the superman for my under two years old boy, though I didn`t and will never beat him. I begin to think. He is going to grown-up. He will find out I am just a common people who is not only don`t know right choice for everything, but also often make some stupid mistakes. How do I want my son to treat me during that time? Do I want to get his patience and understanding? Yes, I will. Like my father who is waiting now. (thanks for helping me revise it)

A wise man and a young man (I try to translate a short story for practicing my writing. And I believe there are many grammar mistakes and bad English in my essay, thank you for helping me to revise them. And please feel free to change the sentences even it is changed the story. ) Long long ago, when life gets difficulties and annoyance, people tend to consult a wise man for acquiring some advices or solutions. One day, a young man walked a long way for meeting an old wise man who was well-known by all the people in the country for his wisdom, vision and lofty prestige. Fate is too unfair to me! I am too poor to marry the girl who I deeply love to. The young man complained. After a short silence, the old man picked up a stone slowly instead of answering anything, then he threw it to the grass field where also lays same stone everywhere. Go to find it out, young man! The old man asked. The young man sought it for a while and gave up soon. The old man then took off his ring, which is a glisten and studded with a large ruby, and threw it to the same grass field as well. Due to that ring was very shiny under the sunlight, the young man finds it out immediately this time. Meanwhile, an imperceptible smile flashed across the eyes of the old man, then he closed his eyes and said: ‘stop complaining, son, as long as you work hard, I believe the gold will shine’ There was not any answer back. When he opened his eyes again, he saw. The young man was running as fast as he can to his coming direction with holding that golden ring.

confusion about " to" and "for" When I write something in English. I often confused about when can I use “to” and when can I use “for”. for example: I think this shirt is good enough for/to me. This gift is not for/to him. when "to" and "for" followed with something and somebody, i don`t know how to handle it. But I can understand that "to" is often used behind verbs. For example, I gave my book to Kim yesterday. thanks!

for my father I`ve read a sentence from a book, which written by a Chinese writer. The first half of life of a man stands behind his father, and his father stands behind him in the latter half of his life. As the limitation of my English ability, it needs your imagination to understand what I am trying to express. That is proved by my experience. My grandfather told me that, when you are 5 years old, your father looks so powerful and wisdom and he just looks like a superman in your eyes. I cannot agree it any more when I was in that age. Because, during that time, for a 5 years old boy, he can do anything, he can beat my buttocks freely if I refused to follow his works and he felt free to buy anything he want. That was my dream, to be a powerful man like him. However, everything is changing in this world, not to mention my thought to my father. During my teenager, I thought that he was right in most of the time, but sometimes I felt I was right. Since I want to study in computer science, but my father told me that I will go to study in mechanical engineering. Although it caused some arguments between us and finally I gave up, now it is no longer bother me. Now, I have my family. I can work to support my life and thoroughly independent from him. I guess I am the superman for my 1.5 years old son, though I didn`t and will never beat him. I begin to think. How do I want my son treat me since he grown up, no matter how new fashioned ideas and thoughts that I have now, when his time come, mine must gone, there must be a gap between us. Do I want to get his patience and understanding? If I wish, my father is waiting now. (as the limitation of my English ability, I only can write it in a very simple way. Thanks for your reading and help)
