HOW ARE TV PICTURES MADE?
A TV picture starts with a TV camera. Some TV cameras are big and some are small. The cameras in TV studios are big. Camera operators roll the big cameras around on wheels. There are usually several big cameras in a TV studio. Cameras used outside a TV studio are smaller. TV camera crews take the smaller cameras to news and sports events.
Some cameras send out live pictures to your TV set. Some cameras make videotapes that get played later on a television program.
All TV cameras need electricity to work. A camera operator points the camera at a scene. The camera picks up light from the scene. It changes this light into an electric signal called the video signal. A microphone changes the sound of people talking or music playing into an electric signal called the audio signal.
As food is to the body, so is learning to the mind. Our bodies grow and muscles develop with the intake of adequate nutritious food. Likewise, we should keep learning day by day to maintain our keen mental power and expand our intellectual capacity. Constant learning supplies us with inexhaustible fuel for driving us to sharpen our power of reasoning, analysis, and judgment. Learning incessantly is the surest way to keep pace with the times in the information age, and an infallible warrant of success in times of uncertainty.
Once learning stops, vegetation sets in. It is a common fallacy to regard school as the only workshop for the acquisition of knowledge. On the contrary, learning should be a never-ending process, from the cradle to the grave. With the world ever changing so fast, the cease from learning for just a few days will make a person lag behind. What's worse, the animalistic instinct dormant deep in our subconsciousness will come to life, weakening our will to pursue our noble ideal, sapping our determination to sweep away obstacles to our success and strangling our desire for the refinement of our character. Lack of learning will inevitably lead to the stagnation of the mind, or even worse, its fossilization, Therefore, to stay mentally young, we have to take learning as a lifelong career.
Hello, ladies and gentlemen. It’s great to be here. First of all, thanks for your coming. Tonight, what I am gonna talk about is innovation. Who can tell me what is innovation? We all know that, since 1978, China has been through the greatest changes brought by the reform and opening-up. So what we can see from the reform and opening-up? The power of innovation. That’s why I am here. I am here to show you my Chinese dream.
I want to talk about the future and how we're going to win it. If we want to make innovation. But firstly, we should make sure that China is a place where we can make it if we try, where we can go as far as hard work and big dreams will take us. We understand that it’s not going to be a cakewalk, this competition for the future, which means all of us are going to have to do our best. We are going to have to win the future by being smarter and working harder and working together. Innovation is the spirit of our country, the motive force for our country’s prosperity.
Sparking the imagination and creativity of our people, unleashing new discoveries -- that's what China will do better than any other country on Earth. From the moment we have a new idea, we can explore it; we can develop it with a research grant; we can protect it with a patent; we can market it with a loan to start a new business. We’ve got a chain that takes a great idea all the way through. We must be confirmed that, today, the challenges we face are real. They are serious they are many. They will not be met easily or in a short span of time. But we will somehow find a way to overcome the difficulties. My major is . My is to discover or create new drugs for many diseases like cancer. You know that laboratory is the place where miracles happen. Believe it or not.
What I do can save millions of people’s lives. For a long time, what challenges me is how to commercialize research. You come up with a great idea, but moving that new discovery from theory to practice or from the lab to the marketplace, that's really a big . That’s what we should focus on. We need to act with a sense of urgency-to study and work and create as if the fate of the country depends on us-because it does. It depends on us. Thank you!
Saying goodbye to childhood,we step into another important time in the pace of young,facing new situations,dealing with different problems.....
everyone has his ownunderstanding of young,it is a period of time of beauty and wonders,only after you have
experienced the sour ,sweet ,bitter and salty can you really become a person of significance.thre time of young is limitted,it may pass by without your attention,and when you discover what has happened ,it is always too late.grasping the young well means a better time is waiting for you in the near future,or the situation may be opposite .
having a view on these great men in the history of hunmanbeing,they all made full use of their youth time ,to do things that are useful to society,to the whole mankind,and as a cosquence ,they are remembered by later
generations,admired by everyone.so do something in the time of young,although you may not get achievements as these greatmen did ,though not for the whole word,just for youeself,for those around!
the young is just like blooming flowers,they are so beautiful when blooming,they make people feel happy,but with time passing by,after they withers ,moet people think they are ugly.and so it is the same with young,we are enthusiastic when we are young,then we may lose our passion when getting older and older.so we must treasure it ,don't let the limitted time pass by ,leaving nothing of significance.
Time flies!Our freshmen have spent two months in our beautiful campus of university. Every new beginning is a new challenge.We can't expect anything to be the same as our imagine.Different envirenment is a new battle.We are always curious with the things around.Though we come from different placeswe have our own dream our own ambition our own challenge.But the mankind is sometimes so fragile that it can't withstand outside lure.
Many students are the first time to be so far away form home.They come to a foreign city a foreign campus facing so many foreign but friendly faces.Plenty of activities bring us fresh air and pleasant fleeing.Be busy with study and work enriches our lifehelping preventing our homesick.
Life in campus is different with that in elementary school and middle school.We have much spare time dominated by our own.Our campus is just like another home.People from all corners of our country come together to form a big family.There are tears as well as laughters.We have troubles but we are also learning to conquer them.We become more and more brave and more and more stronger.We are no longer the little baby that will never grow up in our parents eyes.We are growing up day by day.
I love the life in our university. We have a new starting point a new origin and a period of a brand new life.Our freshmen life is continuing.Please wait and see our brilliant achievement!
Good afternoon everybody! It's my honor to speak here and I am very glad to share my topic with all of you. Today I'd like to talk about “my dream”. I do not just have one dream, in fact, I have three. They are: a healthy life, a happy family and to travel my great country.
I have always admired the long healthy life my grandparents have. They are older than 80 years of age and they are still alive and kicking! How do they do that!? My grandparents plant vegetables and grow rice themselves; even in their old age they still make food for themselves! I guess that is why they can remain healthy. More importantly they remain humble and never ask for too much from life. Perhaps that makes them common, but they live a happy life. My grandmother once told me this:” I do not want to live long, only long enough for some grand children to be running around in my house”. I want to live a long, healthy and happy life just as they have.
Since my graduation from primary school, until now, every time on my birthday I make the same wish. I wish my parents will not fight anymore. I am not complaining that they gave me a bad childhood, they just fight so much! I am unhappy but that does not mean they do not love me. They do! They love me with all their heart. I love my parents also; I want them to live a happy life as well.
I want to travel this great country of ours. I want to see the beauty of our country. I want to see the miracles that made this country great! I want to go from the east to west, from the north all the way down to the south! I have a dream, that one day I can travel and see my country with my family and friends! If that is not possible, seeing my country on my own is good enough also. If I can fulfill all three of my dreams in life, then God can take me away. I would be happy, and l would have lived a full and prosperous life.
Thank you everyone for listening to my dreams.
I thank you!

China is faced with some enormous challenges as it enters the 21st century. In order to ensure the prosperity of our nation and its future generations we must confront and ultimately solve these challenges.
Some of the more pressing issues facing China are universal. These include environmental degradation, over population andthe effects of globalization.
To overcome some of the things we need to implement include:
Enhancing our scientific and industrial technologies in such areas as IT, Bio- tech, AI and Cybernetics.
Further develop public infrastructure in under developed regions.
Promote education reform at all levels.
Introduce sustainable development initiatives.
The implementation of free trade agreement between China and ASEAN.
The benefit to China in introducing these initiatives will be significant and far-reaching. It is important to realize that these initiatives need to filter down through all elements of the society in China. For instance, cutting edge technologies and intellectual properties; the development of e-commerce based economy; an education system that encourages innovation and creativity; increased foreign investment; higher living standards; more efficient use of natural resources.
It is important for us to realize these reforms are both essential and necessary. These will help China to fulfill its vast and unrealized potential on the world stage. It will also contribute more to a globalized world of the new century.
As for the future our task is not to foresee but to enable.
Dear teacher and classmates:
I am very glad to make a speech here in this class again! This time, I'd like to talk something about English.
I love English. English language is now used everywhere in the world. It has become the most common language on Internet and for international trade. Learning English makes me confident and brings me great pleasure.
When I was seven, my mother sent me to an English school. At there, I played games and sang English songs with other children . Then I discovered the beauty of the language, and began my colorful dream in the English world.
Everyday, I read English following the tapes. Sometimes, I watch English cartoons.
On the weekend, I often go to the English corner. By talking with different people there, I have made more and more friends as well as improved my oral English.
I hope I can travel around the world someday. I want to go to America to visit Washington Monument, because the president Washington is my idol. Of course, I want to go to London too, because England is where English language developed. If I can ride my bike in Cambridge university, I will be very happy.
I hope I can speak English with everyone in the world. I'll introduce China to them, such as the Great Wall, the Forbidden City and Anshan.
I know, Rome was not built in a day. I believe that after continuous hard study, one day I can speak English very well.
If you want to be loved, you should learn to love and be lovable. So I believe as I love English everyday , it will love me too.
First, I would like to know, what does your destiny offer you? Happiness, wisdom, a strong body or something else. If I had asked this question to president Nixon, he would probably had said,”Our destiny offers not the cup of despair, but the chalice of opportunity.”
Needless to say, one of the biggest opportunities given to China is the 20xx Olympic Games. Till now, we have used two sevenths of the preparation time. How much changes have you seen? New roads, new subway lines, public-exercising equipments with beautiful colors, large blocks of grass fields, and also lots of modern gyms which are under construction.
Other than those, there are even more good effects brought to us by the Olympic Games that cannot be seen directly. For example, more and more people will get to know China. I’m sure the mysterious Chinese culture will attract them strongly. And the games will also do good to the economy and environment, for it is
gaining the attention of foreign investors and the awareness of environmental protection is being strengthened. What is more, Olympic Games give a unique opportunity to inspire and educate a new generation of Chinese youth with the Olympic values and the Olympic spirit. Now that we have seen so many advances, could you even imagine us losing the holding rights?
I’ve already said a lot about the Olympics and China. But I think everyone should use some time to think of this question, ”Does the Olympic Games have any special meaning to you?”
For us, I mean the Chinese youth, 20xx Olympic Games is a tremendous gift. Because what we are waiting for is to do something significant as repaying the love given to us .The society is just like a ship, and in our dreams the captain is waving his hand and saying ”Hey! Come here and take the helm! ”How charming his voice is, but we have never heard of it in our true life. This morning, however, when we wake up, we will see the Olympic Games waving its hand. After chewing, most of us will have at least one plan about what to do for the Olympic Games. And mine is to be a “comforter” ----that is someone who will give comfort to others.
At the end of my speech, I hope all the preparation will go well, and everyone will show their ability to the world. Let us seize opportunities and give a big smile to challenges.
Good morning, ladies and gentlemen, I’m very glad to make a speech here. Today my topic is “I love you, China.”
Since the day I was born, I began to have a proud name—Chinese. Since the day I began to talk, the most beautiful sentence I’ve ever learnt has been “I love you, China!”
I love you, China, and I’m so proud of being a Chinese. I’m proud that I’ve got the beautiful yellow skin, black eyes and black hair. I’m also proud that I speak the most beautiful language in the world—Chinese.
I love you, China, for I can feel the deep love you give me every day, every minute. Last year, I got an opportunity to visit the United States of America. During my staying there, my father’s boss once invited my family to dinner. While at , he looked at me and asked: “Little boy, how long have you been in America?” “About a month,” I answered, “How lucky you are!” he said, “If you were living in China, how could you learn such perfect English?” I smiled and told him proudly that all the students in China are able to learn English at school. I saw his surprised eyes and said to myself, “I’m proud of you, China ”

"If you don't want to wake up and find you have no pants to wear, you'd better put themon in sleep," goes a popular joke among students. Obviously, campus thefts have becomeincreasingly annoying as they occur far more often than before. And it seems that the thievesare less choosy these days, with their targets ranging widely from bikes, cell phones, purses,pre-paid IC cards to sunglasses, bags, and even underwear. In short, anything that worth adime is likely to be stolen.
What makes students the easy targets? The reasons are not hard to find. But I believe ofall these reasons, the lack of anti-theft alertness is the most important. For lack of alertness,the students tend to leave the doors and windows wide open during sleep at noon or at nightin summer. For the same reason, they'll also leave their bikes unlocked before a store or by aroad, or forget to take away their personal stuff before they go out of the classroom to make aphone call. These acts undoubtedly have increased their exposure to the light-fingeredmonsters.
In order to minimize possible losses, the students must stay on guard in the first place, asawareness of the thefts around often makes a big difference. To be more specific, thestudents should not hide any tempting amount of cash in the dorm. Put it in the bank instead.Besides, do not leave any valuable items unattended. Take them wherever you go. Inaddition, it's advisable to develop a neighbourhood watch programme with other students inthe dorm and neighbouring dorms.
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 temperamental 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 dust.
Whether 60 or 16, there is in every human being's heart 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 optimism, there is hope you may die young at 80.
Never Put off until Tomorrow What You Can DoToday
We have been told that never put off until tomorrowwhat you can do today since childhood. However,there are still many people who like putting off thethings that should do today until tomorrow.Theyhave no plans for their work and their time. As aresult, they will not accomplish their goals in theend. For example, one Sunday I felt so tired after having a football match that I did not finishmy homework even at night. I thought I could get up earlier to go to school the next morningso that I could finish my homework before class. But the next morning I was not able to get toschool in time because of the traffic jam. I was punished by the teacher. It taught me a lesson.From then on I made a determination that I would never put off anything important until thenext day. Please remember: Work today, for you don’t know how much you may be hinderedtomorrow. Seize the present day，cherish every minute you have now and trust the tomorrowas little as possible.
