第二篇：英语PPT讲稿

Good morning, everyone.Today the topic of my presentation is memories of our childhood.Since we all belong to post-90s generation, I guess we must share some similar memories of our childhood.读诗when we look back on……

Today I want to serve as a tour guide, leading you to recall our childhood together.Hope you can enjoy the journey!Now, let’s begin.Our first stop is---“snacks”.Are you familiar with these? The first is Wowo toffee, next are colorful sugars like watermelon but in mini form.Sorry but I forget its name, do you know how to call them …

Okay, beside them are haw slices.Also, the magic pop sugars, it is very interesting that when we put them on our tongue, they will jump and let out the sound like firecrackers.So it’s also named crackling candy.Next is our old friend---ice bar and Huahuadan, which are small black grains.They taste sour and sweet.Have you eaten this?

Next come the cotton candy , the sticky-teeth sugar, Tangseng’s meat, and an old brand soft drinks---Jianlibao.The second stop is---“games”.The first is……I remember we should write characters on the paper and ask a buddy to choose which side he wants, if he is unlucky to choose the one written with mocking words, he will get tricked.The second game is rubber game skipping, girls like this.The third one is hopscotch.Next is making paper airplanes.The fifth is game of chicken.The eagle preys on chickens.Also the Cat’s cradle, I play this with my fellows very often.The last two are spinning top and slingshot.Actually, there are many other games.What else can you remember?

I list a few more, for instance, blowing bubbles, yo-yo, stamping seals and flipping hoodles.Okay, here we arrive at the third stop---“cartoons”.Are you familiar with these?

For example, the Calabash brothers, Captain black cat, astro boy, the lion king, smart Yixiu…

The last stop is concerning “studies”.You see, these are our old edition Chinese and Maths textbooks.The following are illustrations attached to our books, for example, the leaning tower

of Pisa…and his picture is from Si Maguang smashed the jar.翻页

Also, the great friendship between Marx and Engels.The next one is from “Weigh the elephant”, do you still remember this? This is 曹操 and this is his son 曹冲.Okay, this is the end of our journey.(Do you enjoy yourself?)

On reflection, what I want to say is that the memories…..Just as a song goes, “we are all children”.However old we are, I wish the good part in children can be retained, such as a loving heart, warm and innocent smiles, curiosity and purity, etc.Life itself is a journey, hope you enjoy yourself all the time!

Thank you for your attention!

Family planning 标题页

1.Good morning everyone, my name is Lv Shu-ping.Here my topic is “family planning”.You may think it is such an old and common topic, but it is really worth thinking about, isn’t it?

目录页.First, I will show you the outline of my presentation.It consists of four parts.The first part… the second part… and the third, 第一部分（人口膨胀图）

3.this is a thought-provoking picture, in which numerous people are crowding in the Railway station.As we all know China has the largest population in the world, more than 1.3 billion, which is 20% of the world population.4.But the resources on earth are far from enough to sustain our exploding population.At a time when half of the world is suffering from starvation, poor health and a badly low standard of living, we simply cannot take lightly the population problem.If we don't control the birth rate right now, we'll surely lead a miserable life in the near future.Therefore, it is prime time that we took positive steps to hold back this grim tendency

5.The Family Planning Policy is a very good policy to solve this problem.Our country has formulated relevant laws to carrying out family planning policy, such as Population and Family Planning Law of the People's Republic of China 计划生育的优点(站街图)6.In the past, we each family can have three or more children.Parents must go to work hard to support theirs kids.Because their parents are very busy, the children also failed to gain more care and good education.This creates a population decline in quality and people living standard is also reduced.7.Under the guidance of family planning now, In most of cities, a couple only can have one child, and in most of villages, one couple only can have two children.If you have one more illegal children, you will be punished seriously for you have violated the Family Planning Policy.8.When a family have only one child ,Support children for parents is not a great pressure.when life become easier ,They can have more time to enjoy life, can also have more energy to come into work.So they will make greater contribution to the society, It will be mutually beneficial results.9.Due to the home have only one child, the energy which parents used to take care of three or more children are put into taking care one child.So the child can live more comfortable and will be more healthy.10.At the same time, parents can take out the money ever used to education more children, flowers to a child, and make him or she gain better education.11.The Family Planning Policy can lighten the social and national burden, and the Family Planning Policy can make each person share more material and spirit resources.(1)Family planning, make the country for new population of consumption reduced, thus speeding up the capital gains.(2)Family planning, can make every year to the labour of school-age population decline, so as to facilitate the employment.(3)Family planning, the state may take the legacy of the funds for education, make more people are more better education and technical training, so as to improve the quality of the whole nation's population of purpose.(4)it is better to optimize the allocation of resources and increase the per capita resource level.第二部分（引起的问题）

12.Like everything has two sides, family planning also has some disadvantages

(1)For example, there are two families, both of the families have only one child, a girl and a boy.if the boy and the girl married, they have to take care four old people, If they have grandparents, Their burden will be bigger.And if the old people are in different places, how can the couple take care well of all these old people.In addition, the only kid always will be spoiled by the parents, and it is not good for the kid's growth, and the kid has no sister and brother.He will be lonely too.And the old people who lost their children by accident, but they can not have the second child.Who can take care of them? They are always lonely in their old ages(2)From these pictures, we can also see that, along with the family planning policy implementation, our country population structure changes, The family planning policy leads to fertility rate decreased dramatically, young population percentage drops, elderly population ratio rose, working age population growth slowed Such changes to Chinese society brings about many challenges(3)In traditional Chinese thinking, If a family is allowed to have only one child, a lot of families hope is a boy.This idea cause gender ratio become unbalanced, there are more boy than girl.As a joke say, there will be a part of the boy can’t find the girlfriend, this will also brings to the society some other problems, such as high divorce rate, sexual violence crime etc.第三部分（是否要放开计划生育）

3.1 Views against one child policy 3.1.1 Growth of only children

Selfish and lonely of only children is closely related to the our social environment, the living environment, cultural environment and network environment.If we don't improve our social and living environment, Even if, two children, three children or more, can not change the children's selfish.3.1.2 Endowment China is gradually promoting and realizing “universal health and pension insurance system”.As long as parents alive they will get the guarantee of health and life.As long as children do not always depend on their parents, they will not undertake more pressure.3.1.3 Population growth Since China's one-child policy be implemented in 1979, Population growth rate constantly slow down.It delays four years for our country's 1.3 billion population day, and reduce the excessively rapid population growth of global pressure, 3.1.4 Aging of population Expert views: even if two foetuses policy is open universally right now, the aging of population problem，the proportion of old people will only reduces from 31% to 29%.This can only slightly ease the aging of population problem, cannot solve the actual problem.Only by increasing employment rate, improve the quality of workers and developing the potential of old workers can we solve this problem.3.1.5 Other problems Sex ratio imbalance, population base down and cheap labor exhaustion factors are temporary, the ecological unbalance is not ascend to the political theory height.支持者的观点

3.2 Views supporting two child policy 3.2.1 Aging of population Broadening family planning will relieve the country's aging degree and reduce its negative effects.The additional children deriving from broadening family planning policy will enter the job market 20 years later.Broadening family planning can reduce the pressure of labor shortage in job market.3.2.3 Population quality At present people in ethnic minorities and rural areas can bear more than two children, but the city's population can only have one child，which actually formed inverse population elimination.As is well known, the overall quality and economic level of urban population are superior than that of rural and minority nationality areas.So broadening family planning can improve the overall population quality.3.2.5 Sex ratio Broadening family planning is good to improve sex ratio.sex ratio imbalance problem caused by one child policy will be solved by opening two foetuses.Root of human trafficking of children is that child is a kind of rare resource.Many families that do not have a boy and was forcibly ligation will go for a son to raise.If people get satisfaction of birth, then there will be many family who lost the desire to buy children.个人的观点

In my opinion: Social problems caused by family planning really need to be solved.Broadening family planning is a gradual process.（论文中）

4.Conclusion Personally，I support the release of two foetuses policy.For individuals, only children don't have the full family fun；In theory，people should have a spontaneous adjustment process.One-child policy is a forced policy but not an ideal policy.If the conditions change, we will have to change our policy.For employment, two foetuses policy will not increase the employment pressure in the short term.Newborn babies will impact in 20 years later and social demand will increase greatly during the 20 years，which will create more employment opportunities.For population quality, because compulsory education popularization has been universal, education resources shortage will not appear.Of course, the implementation of two foetuses policy gradual process and may need test in advance，many problems is demanded to be considered.Broadening family planning is a kind of attitude, while born not is a choice.This reflects the attitude that everyone is equal in fertility.People who don't like children and those lacking of raising ability can chose to don't have a kid or Have fewer children, while those people who have the ability to raise and can ensure that their children can get a good education and the development can choose to have more children.

第四篇：青春 英语ppt演讲配合稿

Youth is not a time of life;it is a state of mind;it is not a matter of rosy cheeks, red lips and supple knees;it is a matter of the will, a quality of the imagination, a vigor of the emotions;it is the freshness of the deep springs of life.Youth means a tempera-mental predominance of courage over timidity, of the appetite for adventure over the love of ease.This often exists in a man of 60 more than a boy of 20.Nobody grows old merely by a

number of years.We grow old by deserting our ideals.Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.Worry, fear, self-distrust bows the heart and turns the spring back to

Whether 60 or 16, there is in every human being’sheart the lure of wonder, the unfailing childlike appetite of what's next and the joy of the game of living.In the center of your heart and my heart there is a wireless station: so long as it receives messages of beauty, hope, cheer, courage and power from men and from the Infinite, so long are you young.When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old, even at 20, but as long as your aerials are up, to catch waves of dust.optimism, there is hope you may die young at 80.All endings have been written,All tears have been on the way.Suddenly the beginning was forgotten

In the past old summer day.No matter how hard I trace my mind,Young you passing like a cloud and wind

Fuzzy seems your smiling face,Slowly fades in eve mount haze.Then I open the book to flyleaf yellow,Only to find the fate binds it so hollow.In tears at the book again and again I look,I have to admit youth is too hasty a book.An individual human existence should be like a river—small at first, narrowly contained within its banks, and rushing passionately past boulders and over waterfalls.Gradually the river grows wider, the banks recede, the waters flow more quietly, and in the end, without any visible break, they become merged in the sea, and painlessly lose their individual being.

第五篇：学术交流英语PPT讲稿

30s

Good afternoon, everyone.The title of the paper is Visible Microspectroscopy for Diagnosis of Gastric Precancer.Its author is Liu Yong from Department of Physics, Zhao qing University.It’s presented by Li Mengfan from CAS, Hefei Institutes of Physical Science.You can know more about cancer and the new method to diagnose gastric precancer after reading this paper.58s

Cancer is very common among human beings.It is mostly related to the habit of the patients, the job, the environment, the drinking water and the soil matters, too.If a person is affected by certain bacteria, he may also get gastric cancer.Bad habits like smoking, drinking, mental tension, eating improperly and living irregularly increase the possibility of having cancer.Before specific treatment, the doctor should make sure whether the patient has cancer and where the focus is.The method used to diagnose cancer and locate the cancerous area is very important.42s

Before we design a method to diagnose cancer, we should know more about cancer like where it starts and what it causes.Firstly, about 90% of the human’s cancer start from the epithelial layer of skin, internal organs and tubular organs in the body.Secondly , cancer usually accompanied by the changes of organization structure in the cell level.So, the changes which appear in the structure of organization and chemical composition provides important evidence for diagnosis of precancer.42s

Normal method to diagnose gastric precancer is Reflectance spectroscopy.It’s very prospective in early diagnosis of cancer and is commonly used these years.One of the most common technology is diffuse reflectance visible spectroscopy, it can acquire the approximate information of the target tissue.This method is low cost, fast and non-invasive, it provides important means for diagnosis of malignant damage of organization of human organs.However, there are also some disadvantages of this method which need to be improved.55s

This is the system of diffuse reflectance spectroscopy, the light beam emitted from the tungsten halogen lamp is guided into the integral ball by the source fiber.The light come out of the integral ball irradiate the standard board, the reflected light of the standard board is treated as the background.Then take target tissue substitute for the standard board, and scan the reflected light of it.The reflected light spectra of the gastric tissue mucosal layer and the submucosa layer is guided into the spectrometer by the collector fiber.The spectrometer and the computer is connected by USB, spectrum can be processed using computer.36s

First of all, only average visible spectrum of the target tissue can be acquired, it means that the docters cannot make out the location of the cancerous tissue precisely.What’s more, the device is easy to be affected by changes of optical path length induced by different set-up of prober and the variation of hemoglobin concentration due to the pressure between prober and tissue.50s

To avoid the problems of the commonly used techniques, diffuse reflectance visible spectroscopy, scientists do a lot of researches to find out a new way to diagnose precancer.The new method is Visible Microspectroscopy.The visible microspectroscopic measurement device is accomplished on the basis of fiber confocal microscope, its 3-d imaging principle devote to the optical tomography ability of the system.The visible microspectrum of cancerous and normal tissue can be analysed and contrasted, so it’s more useful than the normal method.45s

This is the structure of the visible microspectroscopy device.The fiber coupler can separate the lighting beams from the signal beam.The two lens can focus the light on the tissue ，The 3-D electronic controlled platform move along the direction of optic axis, so that the device can acquire the visible microspectroscopy signal of the sample in different depth, precisely locate the boundary of the cancerous tissue.The signal measured from different position can be stored in the computer after analysed by the spectrometer.31s

This is the spectrum chart of the normal tissue and cancerous tissue, they are analyzed by the spectrometer before being transmitted to the computer.The upper chart is the visible spectrum of normal tissue, it is regular.Contrasting to this, in the nether chart, the spectrum of the cancerous area shows that the strength of reflected light grows as the wave length grows.49s

In comparison with the normal method, there are a lot of advantages of the new method.Firstly, the structure of visible microspectroscopy device is very simple.The main parts consist of source, fiber coupler, 3-D electronic controlled platform, spectrometer and the computer.Secondly, the 3-D space microspectrum can be acquired , which can help the doctors efficiently make out whether the gastric tissue is cancerous.What’s more, the optical tomography ability enabled the device to precisely locate the edge of the cancerous area.32s i.ii.iii.In conclusion, the main goal of this research is to find a new way to diagnose the gastric precancer.The spectrum of the normal and cancerous gastric tissues which can be measured by visible microspectroscopy in cell level is the central idea.This new method can obtain the cell level information, and is not affected by changes of optical path length and hemoglobin concentration.50s

i.The device is very simple, so it can have a small size, which can reduce the sufferings of patients.It can efficiently make out whether the tissue is canceration.ii.Besides, the 3-D space microspectrum and optical tomography ability can make the device accurately distinguish the cancerous tumor area from the normal tissue in cell level, thus the boundary of the cancerous tissue can be ascertained accurately.iii.The result of the research shows that this device may be used to non-invasively diagnosis of early gastric cancer.20s

This device is only researched in the lab, there are still a lot of works to do to make this device applied into practice.So, special design of this device should be made which can be applied to the medical diagnosis.
