牙医检查牙齿时,常用一个带把的小镜子,在放入口腔之前,总要把小镜子放在酒精灯上烤一烤,这样做的目的是?

一般是平面镜
我记得有些是凹面镜,反正绝对不是透镜

1.照相机,幻灯机,放大镜,都是凸透镜
照相机成倒立缩小的实像,
幻灯机成倒立放大的实像,
放大镜成正立放大的虚像
2.潜望镜,穿衣镜,牙医内窥镜都是平面镜
三者都是成正立等大的虚像.

Patient:Doctor,I'd like to have a check-up on my teeth.
Dentist:please sit down.What is your trouble?
Patient:I have a tooth that bothers me often.
Dentist:Show me which one it is?
Patient:The last one in my right upper jaw.
Dentist:Let me examine your mouth.I can see you have two bad teeth.Do you like eating chocolates or candies?
Patient:Yes,I do.I love them very much!I am used to eating lots of sweet food.I have tried to quit it but I just can’t.
Doctor:Oh,I see.Er…One of them doesn’t seem so bad.I think it can be filled.But the other one should be taken out.
Patient:Will it hurt?
Dentist:No.I will give you an injection to keep you from feeling anything except numbness.Don’t move while I give you the injection.Do you feel numbness in the area now?
Patient:Yes,I do.
Dentist:That’s good.It is the time to take it out.
（操作中.）
Dentist:OK.Here are two tablets.Take one when you feel any pain.Please remember,don’t eat too many sweet things.They are not good for your teeth.And you should brush your teeth twice a day or three times a day.
Patient:I am better than before now.Thank you very much,I will take your suggestion into consideration.Goodbye doctor.

1,花店运用平面镜反射使花店看起来更大更明亮
2,牙医运用平面镜反射,看清口腔内不易看见的地方

反射:潜望镜,穿衣镜,牙医内窥镜
折射：老花镜,放大镜

you had better go to see a dentist

（1）医生为了看清病人口腔内无法直接看到的位置的病情，需要借助小平面镜，即将平面镜放入口中，通过看该部位平面镜中的像来观察病情．当冷的平面镜放入温暖且水蒸气非常多的口腔内，会有水蒸气遇冷液化而吸附在平面镜上，导致医生看不清发病位置的像．为了看清病情，就要防止水蒸气液化，所以给平面镜加热一下．
（2）声音能够传递信息的例子有：利用超声波探测海底深度、利用超声波探测鱼群、B超、医生用听诊器为病人检查身体等；
故答案为：防止口腔中的水蒸气液化；B超．

Her mother brought her to see the doctor and let her have braces.

Five,marketing combination strategy
(a) product strategy
Fe dry brush Golden dental toothpaste has a unique way to brush your teeth,use dry brush,followed by Golden dentist bio enzyme is added to improve product performance,with a distinct personality,with a strong distinction with other toothpaste,has irreplaceable advantages other toothpaste,have great originality.Only in this way can the one and only,favored by the market,not produce aesthetic fatigue.
Research shows that,"FE" is killing and lysis of 400 kinds of bacteria,also has the obvious inhibitory function of Helicobacter pylori,often use FE toothpaste or FE oral spray,not only can solve a series of oral problems,also is helpful to chronic gastritis.In addition,because oral unclean and food residue for protein,easily by enzyme decomposition,the gap of bio enzyme some toothbrush cannot reach full penetration,can be gently cleaning teeth and oral cavity.
(two) the price strategy
Fe dry brush Golden dental toothpaste at present mainly in the high-end market positioning,application of some high-end materials configuration,so that the toothpaste performance to the forefront of similar products,so the price of toothpaste is relatively high.But with the development of technology and the improvement of the technology,it will slowly reduce the price.Golden dentists also some end products,while maintaining lower toothpaste material constant quality and technology,the lower price range,meet the end consumer,let people get to meet.

可翻译为：How often do you see the dentist?Twice a year.

1如果你牙疼,你应该去看牙医 if you have toothache,you should go to the dentist 2吃大量的蔬菜有助于健康 eating a lot of vegetables do good to your helth.3你父亲多久锻炼一次 how often does your father do excercise?4他几乎不锻炼 英语翻译 he hardly does excercise.

I have an appointment with dentist.

透镜和面镜,前者可以透过光线,后者可以反射光线
照相机幻灯机放大镜是凸透镜,穿衣镜牙医内窥镜是面镜.

What will she do next Sundy?

1. see a dentist
2. have a cold
3. have a headache
4. drink hot tea
5. have a stomachache
6. lie down and rest
7. have a fever
8. a good idea
9. feel well
10. give me some advice

解题思路：平面镜既可以成像，还可以改变光线的方向，潜望镜是利用了平面镜的这一特性，平面镜成正立、等大、虚像．

①利用平面镜扩大视觉空间利用平面镜成像原理；
②④牙医为了看清牙齿的背部使用的平面镜和潜望镜既利用了平面镜成像，又改变了光线的方向；
③舞蹈演员利用平面镜观察和矫正自己的姿势利用平面镜成像的原理；
因此②④既利用了平面镜成像，又改变了光线的方向．
故选D．

点评：
本题考点： 平面镜成像的特点、原理、现象及其实验方案．

考点点评： 本题考查学生对平面镜的作用以及平面镜成像特点的理解和掌握．

yesterday she went to a dentist to clean her teeth

三个孩子在玩在地板上,他们的母亲,告诉他们不要吵.一个婴儿把报纸撕碎,弄的一团糟.他说:我太累了,读同样的老杂志一遍又一遍.他目不转睛地看着我们说：“你不介意我下次去了?我有可怕的牙痛,我不能再等一会儿.”他盯着所有人,说：“你介意我去下一个?我有可怕的牙痛,我不能再等了.“

解题思路：平面镜属于反射镜，能对光线进行反射成像；人呼出的水蒸气温度较高，若遇到温度低的平面镜，水蒸气就会发生液化形成小水滴，镜面就变得模糊不清．烤一烤，升高了镜子的温度，也就防止了水蒸气液化．
超声波能够传递信息．

口腔科医生利用光在镜子表面发生反射的现象，利用了平面镜成正立等大的虚像的特性，方便地观察观察牙齿背面；烤一烤，是为了使平面镜的温度升高，以免水蒸气在镜面上液化形成水雾．
医院用“B超”给病人诊断疾病，是利用超声波传递信息．
故答案为：观察牙齿背面；防止口腔中的水蒸气在小镜子表面液化；信息．

点评：
本题考点： 平面镜对光的作用；液化及液化现象；声与信息．

考点点评： 本题考查了平面镜对光线的作用、液化现象、防止水蒸气液化的方法以及电磁波的作用，是一道基础题，联系生活实际，体现了物理来源于生活，服务于社会的新课程理念．

1.喉咙疼 sore throat2.躺下休息 lie down to have a rest3.带蜂蜜的热茶 hot tea with honey4.看牙医 go to see the dentist5.喝大量的水 drink a lot of water.drink a big amount of water6.早睡觉 go to bed/sle...

解题思路：

物质由气态变成液态的过程叫液化，液化是吸热的；液化的方法有两种：降低温度和压缩体积。镜子的温度升高后，病人口中的水蒸气(气态)不会遇冷凝结成小水滴(液态)，发生液化现象，从而能使医生利用镜子的平面镜成像原理清楚地观察病人的牙齿。

The dentist's advise

Doctor: hello, is a tooth or filling?
Patient: filling!!!!!
Doctor: ceramic, the simulation of which would you like?
Patient: which better?
Doctor: depends on your needs?
Patient: I'll have the simulation, how many money?
Doctor: one million
Patient: as long as the endowment food good, no problem.

1、潜望镜的成像特点---物镜接受光线成像后,经二级平面镜折射后,进入物镜.
2、透镜和平面镜的特征各是什么---分别是透镜成像、平面镜折射.
3、潜望镜和牙医内窥镜各是什么镜---应该都是凸透镜.现代牙医的内窥镜应该是光纤传导.

医生告诉他:你应该(you should).brush your teeth every morning and evening.( 每天早晚刷牙） Don't eat too much sweet food(不要吃太多甜食）and its the best if you doesn't eat anything after you brushed your teeth everynight befor you go to sleep(在每晚睡觉前刷完牙以后最好不要吃任何东西）. If possible go to dentist once or twice a month(如果可以的话,每个月去看一两次牙医）.
你没说要写多长哦...我想不出来还有啥要求了0_0 字数不够的话给点提示,我在给补上

不凹也不凸,是平镜.用途是通过反光帮助医生看清口腔中眼镜难以直接看清或看到的地方.这个镜子很有用,口腔科必备.
