试题解析

咬伤

概念咬伤(bite mark)是指人或动物的上下颌牙齿咬合所致的损伤,在攻击和防御时均可形成。由于人体牙弓形态、牙的排列和疏密以及生理、病理变化的不同,加之又会有牙的修复、脱落等变化的影响,所以牙的咬痕具有良好的个体特异性。咬伤的特点轻微的咬痕仅在皮肤上留下轻微的痕迹,并很快消失;稍重的咬痕形成皮下出血伴有擦伤;更重的咬伤使皮肤的完整性遭到破坏,形成挫裂创甚至组织器官缺损,创缘不整齐。较多见的是以对称的半弧形几个牙印构成圆形或椭圆形的咬痕,常见于面颊、肩部、乳房。在手指及其他突出部位,如乳头、鼻、耳等,咬痕可呈基本对称地分布在对应的两侧面上,上、下颌牙形成的咬痕不融合;严重者组织或器官部分缺失。不同部位的牙及牙列形成的咬痕是有区别的。一般情况下,上颌牙咬痕较下颌的大而长,且损伤也重;上颌牙排列较下颌牙松散,上颌中切牙牙冠较大,切面较薄较直,形成相对较长的 “一”形咬痕;下颌中切牙牙冠较小,

Directions:In this section, there is a passage followed by 5 statements. Go over the passage quickly and mark the answers on the Answer Sheet. For questions 1 - 5, mark  Y (for Yes) if the statement agrees with the information given in the passage;  N (for No) if the statement contradicts the information given in the passage;  NG (for Not Given) if the information is not given in the passage.  Questions 56- 60 are based on the following passage.  After I left Debrecen I walked for days and put up my tent at night. An old couple driving a horse and cart stopped and spoke to me. I tried out my broken Hungarian and they laughed. But it was obvious they were offering me a lift, so I got up on the cart, with my backpack and tent. They offered me some fiery apricot liqueur, home-made by the look of it. We drank it from the bottle.  The land was flat. You could see forever. You could see as far as the future. At first we could still see the Hortobagy River, brown in the weak sunshine, and carpets of sunflowers. But then, as we jolted along a track in the cart, there was just the puszta—the dry Great Plain of Hungary. It’s where the Hungarians grow their wheat and catch their wild horses.  A Hungarian poet once said that the earth and the sky are one in the puszta. I understand what he means. As far as you can see in every direction, the sky comes down and touches the land. This dry yellow land is not beautiful in the usual sense, but being in it, being part of it, I felt a great sense of peace. I have always hated mountains and skyscrapers because they are bigger than I am. But this ... When I lay down and watched the puszta from the back of the cart, it was like being in a great safe flat bed that had no sides but just went on forever. It was then, at that moment, that I felt I could do anything in the world that I wanted. I was eighteen years old.  Then, in the distance, we saw the horses. At first there was just a cloud of dust. Then, suddenly, about ten small, wiry, brown Hungarian wild horses charged across the Great Plain. They got near enough for me to see them tossing their heads. Two csikos, Hungarian cowboys, were chasing them. The cowboys saw the cart and shouted something. The old man shouted something back and he and the old woman laughed. They said something to me in Hungarian, probably trying to explain what the cowboys had said.  I fell asleep. When I woke up, the horses and the two csikos had gone but nothing about the scenery had changed. We were still moving forward but it was as if we had stopped.  I didn’t want us ever to arrive anywhere. I wanted to stay on that cart in the Great Plain forever. But at the same time I knew that when the journey was over, everything was going to be just fine. And it was.  Statements:  1.Debrecen is a town in Hungary.  2.The writer felt a sense of horror because nothing in the scenery was bigger than her.  3.The writer liked flat scenery better than mountains.  4.The grass on the Great Plain didn’t change very much.  5.The writer described a moment when she knew that everything in her life would be bad.
