1 在海上或沙滩上，有时会看到高楼大厦、热闹市场、实际大海、沙漠上并没有这些楼市，这种现象叫海市蜃楼，出现海市蜃楼的原理是：A.光在直线上传播B.光在云层上反射C.光沿直线传播D.光在不均匀的大气层中折射说明选择的原因最佳答案D 课本上有，就是光的折射，光在不均匀的介质上会发生折射，把其他地方的景象折射过来2一般成年人有多少颗牙齿？28～32个最佳答案人类的恒牙列共有三十二颗牙，其中最后萌出的四颗第三大臼齿，位于上下左右牙弓的最后方，因为萌出在智能成长后十六到廿四岁，所以又有智能齿之称，简称然而，由于演化及食物精化，人类的颌骨，因为不再需要强大的咀嚼力而有逐渐变小的趋势，在这变小的颌骨上如要容纳跟以往相同数目及大小的牙齿，则牙跟牙之间往往会有空间不足的问题，于是拥挤，长倒，长弯，或长不出来的情形便发生，这就是阻生。
就统计上而言，长不出来的情形最常发生在智齿，所以习惯上常称这种长不出来的智齿为阻生智齿。
在临床上看起来，大多数的人应该都有智齿。
什么样的智齿应该拔除？智齿牙位不正常，与邻牙形成间隙者；智齿牙位虽正常，但智齿牙冠有骨组织或牙龈瓣覆盖，经常发生冠周软组织发炎、肿胀、疼痛者；智齿已龋坏，或发生牙髓炎，又不便进行牙体牙髓治疗者；因正畸需要，如预防后牙向前移动和防止前牙拥挤加重者，均可考虑拔除。
什么样的智齿应该保留？智齿的位置比较正，预计能正常萌出者；智齿冠周软组织没有发炎和疼痛史，智齿没有龋坏者；有对牙合牙齿并有咬合关系者；通过龈瓣切除可消除盲袋者，应考虑保留该智齿。

“The Shawshank Redemption”is a movie moved me most, although it is a 1994-production movie, nowadays, whenever I think of the actor’s lines:” some birds are not meant to be caged, their feathers are just too br ight”, I encourage myself to work hard for my own objective. It is a movie talked about an innocent people is misunderstood to be prisoned, and he pays unyielding effort to escape from it for his freedom, he digs a hole in the wall year by year and exposes the corruption of the warden, finally, he escaped from the prison and the warden suicided.Sometimes we are misunderstood by some people of something, only we can do is to explain the thing and make effort to convince the people who query yourself, it is not about the thing itself, it is proving the misunderstand wrong, this is why I always work and study hard, and this can guarantee I have the courage and ability to handle all the things well.网上的阿甘正传影评<Forrest Gump> Film reviewForrest Gump who is unfortunately to be born with a lower IQ and the muscle problem, usually, people always think this kind of person can't be successful in doing anything.

Success of < Forrest Gump>, make Tom Hanks become one of the most popular movie stars in Hollywood too.

After viewing the film, I would like to share my impressions of this moving animation from the notes taken in the class here.1 Blood is thicker than waterThis proverb is embodied thoroughly in this movie. Simba grows up with the company of his parents' love. His mother Sarabi is gentle and elegant. Although she is not mentioned frequently in the movie, but the audience can infer that Simba' s good manner is owe to her utmost care. While Simba' s father Mufasa is serious and mighty. He teaches his son skills to survive – such as pouncing – and principle which would be useful to Simba in his whole life, such as" There' s more to being a king than getting your way all the time. " " As a king, you need to understand that balance of life and respect all the cr eatures." " Being brave doesn’t mean looking for trouble" and so on. Once realizing Simba is in danger, Mufasa will run to rescue his son immediately. I Believe that most of whom have seen the movie will be moved by this scene: Mufasa runs to the gorge and saves Simba from being trampled to death by the stampeding wildebeests, he leaps and dodges, comes close to Simba, holds him in mouth and puts his son in a safer place. But when he claws himself up the steep cliff side and tries to get on, he is pushed back down into the gorge by Scar and died. What makes Mufasa ignore the danger coming to him and run to rescue his son? What makes the audience so moved and can' t help tearing? Yes, it is the love of Mufasa, the truly and deeply love which is willing to be given but for no feedback from a great father.2 A friend in need is a friend indeedSimba is in a loss after his father' s death. He runs away from the pride lands and faints from exhaustion on an open plain. Fortunately, Pumbaa and Timon save him just in time. They carry Simba to a shady place and wait until the lion cub comes to, and then they keep Simba in their place and share their problem- free philosophy with him, just as Timon tells Simba" You should put your past behind you”. So the phrase" Hakuna Matata" helps Simba to release from depression and self- condemning, and their friendship makes Simba live happily there. Then Simba' s another friend- Rafikiappears, he is glad to see Simba is still alive, but at the same time, he also hopes Simba to exert himself and take the responsibility to be the king again. So one day, Rafiki finds Simba and leads Simba deep into the forest .He helps Simba to" see" his father. The lion cub is inspired by the late king, and clears the puzzle in his heart. Rafiki also conducts Simba to find a way to future and to take his responsibility that owes to him. " The past can hurt, but the way I see it you can either run from it or learn from it." Simba chooses the latter and goes back to his kingdom to challenge Scar. Surely his loyal friends-Timon, Pumbaa and Rafiki-all gather to help him, just as Timon says: " If it' s important to you, we' re with you till the end." They fight bravely, and defeat the evil Scar, clear the path for Simba to be crowned king of Pride Rock at last. Conclusion can be drawn that it is the firm friendship that supports Simba, makes him feel that he is not alone, gives him strength and helps him to triumph.3 The spirit of looking back bravely and forward hopefullyBefore the truth uncovered, Simba thinks he himself leads to his father’s death .He runs out of pride land, and runs from the past as well .The voice of himself “What would it prove anyway? It won’t change anything .You can’t change the past” dwelt on in his mind. But under the help of Ra fiki, Simba finally knows that he doesn’t have to change the past. Since it had already happened, it’s no use to regrets doing it, the wise way is just let it be, but not forgetting the experience gained from it. So his Father’s words “You are more than wh at you have become .You must take your place in the circle of life” rekindle in Simba a long forgotten ambition to rule, finally he faces his past bravely, gets the sense of responsibility and goes back to fight for his kingdom with the help of his loyal company .The lion king’s rough experience inspire me a lot. Surely, there are indeed many things that makes us feel painful and fearful, but once they happened, they need to be faced up instead of being avoided. What we should do is to make a deep thought and decision about how to take the next positive step. Maybe it will takes a long, hard time to make them, but it doesn’t matter, because avoiding reality only means burdening one’s soul and constraining one’s courage. Human beings need to go ahead because there will be wilder prospects waiting to be explored .The past maybe heavy and gray, but the future is bound to be hopeful and bright-as long as you unload burden, pick up the spirit of “laughing in the face of difficulty” and greet future positively and aggressively .So no matter how long the pain would last, you should remember not to let the pain disturb your normal and daily life too much, just arrange the mind and take the first step bravely, then you will finally conquer the difficulties and find you yourself have already stepped out of the gray past and stride forward into the indefinite but surely hopeful future.。
