机器翻译的毛病很明显，什么‘公羊’都跑出来了。Drilling and Milling Machines 钻机与铣床A shaper utilizes a single—point tool in a tool holder mounted on the end of the ram．Cutting is generally done on the forward stroke．The tool is lifted slightly by the clapper box to prevent excessive drag across the work，[1]which is fed under the tool during the return stroke in preparation for the next cut．牛头刨床使用的是安装在冲压床尾端刀架上的单刃刀具，切削动作一般是在进程时完成。刀具被摆动刀架稍微抬起以防止装置上面产生过度阻力，【1】在回程时被送至刀具下面以便准备另一次切削。The column houses the operating mechanisms of the shaper and also serves as a mounting unit for the work—supporting table．The table can be moved in two directions mutually perpendicular to the ram．The tool slide is used to control the depth of cut and is manually fed．It can be rotated through 90 deg．on either side of its normal vertical position，which allows feeding the tool at an angle to the surface of the table． 刀具的传动机构安放在桩柱里，桩柱也被当为整个装置的底座——支撑台。支撑台可以双方向移动，垂直于冲压床。手动输入的进给刀架用于控制切削的深度，在其正常竖立位置的两边可以旋转90度，这样可以与支撑台形成一个角度进给至刀具。Two types of driving mechanisms for shapers are a modified Whitworth quick—return mechanism and a hydraulic drive．For the Whitworth mechanism，the motor drives the bull gear，which drives a crank arm with an adjustable crank pin to control the length of stroke．As the bull gear rotates，the rocker arm is forced to reciprocate，imparting this motion to the shaper ram． 刀具有两种驱动机构，经过改进的惠氏急回机构和液压转动。惠氏机构的电机转动重载齿轮，驱动一个带有可调整销钉的曲柄以便控制进、回程的长度。当重载齿轮转动时，摇杆被迫往复运动，将之传至冲压床。The motor on a hydraulic shaper is used only to drive the hydraulic pump．The remainder of the shaper motions are controlled by the direction of the flow of the hydraulic oil．The cutting stroke of the mechanically driven shaper uses 220 deg．of rotation of the bull gear，while the return stroke uses 140 deg．．This gives a cutting stroke to return stroke ratio of 1．6 to 1．液压刀具的电机只用于推动液压泵，液压油的流向控制着剩余刀具运动。机械驱动刀具的切削进程使用重载齿轮220度回转，回程使用140度， 切削进、回程比例是1.6：1。[2]The velocity diagram shows that the velocity of the tool during the cutting stroke is never constant，while the velocity diagram for a hydraulic shaper shows that for most of the cutting stroke the cutting speed is constant．The hydraulic shaper has an added advantage of infinitely variable cutting speeds．The principal disadvantage of this type of machine is the lack of a definite limit at the end of the ram stroke，which may allow a few thousandths of an inch variation in stroke length．【2】根据速度图的显示，刀具在切削进程时的速度是不恒定的，而液压刨床的速度图却显示切削时的速度大多数是恒定的。切削速度可以无极调速是液压刨床的优势；这类机械的主要缺点是冲压行程的末端没有明确的界限，可能会造成行程长度有几千份之一英寸的变异。

We Are The World ,We Are The Future

Someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”.

I don’t know who wrote these words, but I’ve always liked them as a reminder that the future can be anything we want it to be.

We are all in the position of the farmers.

If we plant a good seed ,we reap a good harvest.

If we plant nothing at all, we harvest nothing at all.

We are young.

“How to spend the youth?” It is a meaningful question.

To answer it, first I have to ask “what do you understand by the word youth?” Youth is not a time of life, it’s a state of mind.

It’s not a matter of rosy cheeks, red lips or supple knees.

It’s the matter of the will.

It’s the freshness of the deep spring of life.

A poet said “To see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour.

Several days ago, I had a chance to listen to a lecture.

I learnt a lot there.

I’d like to share it with all of you.

Let’s show our right palms.

We can see three lines that show how our love.career and life is.

I have a short line of life.

What about yours? I wondered whether we could see our future in this way.

Well, let’s make a fist.

Where is our future? Where is our love, career, and life? Tell me.Yeah, it is in our hands.

It is held in ourselves.

We all want the future to be better than the past.

But the future can go better itself.

Don’t cry because it is over, smile because it happened.

From the past, we’ve learnt that the life is tough, but we are tougher.

We’ve learnt that we can’t choose how we feel, but we can choose what about it.

Failure doesn’t mean you don’t have it, it does mean you should do it in a different way.

Failure doesn’t mean you should give up, it does mean you must try harder.

As what I said at the beginning, “we are reading the first verse of the first chapter of a book, whose pages are infinite”.

The past has gone.

Nothing we do will change it.

But the future is in front of us.

Believe that what we give to the world, the world will give to us.

And from today on, let’s be the owners of ourselves, and speak out “We are the world, we are the future.”

good evening , ladies and gentlemen .

i am joy and glad to give you a speech about stre, yes , just the topic you see on the screen.

psychologist tell us that streis a state of worry caused by the problem of living , such as too much work or study , heavy responsibilities , and quickened pace of life .

statistics show that strecomes from every detail in our life .

financial problems , poor health , being laid off may be the strethat most adults now suffering .

as students in the university , we are also under our special stre.

while study , having to take various tests and submit a project against a deadline may put a great pressure on us .

and the things make us felt stressed may be our parents’s greater expectations on us than we could reach .

later , when we are likely to graduate , some other problems will also annoy us .

i think we will worry a lot about our ability to compete in the job market and how we can best use what we’ve learned at college in our future job .

the chief problem we should face to is our atitude towards stre.people usually say they can not live in the sun except they escape from stre.

it’s unwelcome ! yes , however , very necessary .

just image a world where stredoes not exist and people lead their life in a very comfortable way .

but is this kind of living condition as perfect as we hope ? without stre, they may feel very satisfied with the current life but lack of power to discover new things .

too much siteapp.oh100.com result in nothing except a countermarch of the society .

no stre, no development .

so a certain amount of streis good .

it can stimulate us and increase our level of alertne.

and our answer to streis another vital problem .

how to do with ourselves when stresuddenly break into our life ? to wave the white flag and admit our unability , to give up to our ideality , or worstly , just to suicide as to put an end to everything … of cause not .

the principle is to tackle with stregentlely and harmoniously.

we should try our best to release ourselves .

such as to do some exercise , to linsen to traditional chinese music or classical music to ease our minds and to learn to view these changes of life as challenges .it’s no use crying over spilt milk .

only to accept what has happened can solve the problem .

ok , i think i was under large stre3 minutes before , but now i am here and have finished my speech .

here is the last thing i want to add to my topic ,face to it and overcome it ,streis also a piece of cake.

Weve all been taught that we should help people.

It is the right thing to do and will make us popular with others.

It may even win us favors in return.

However, we must be realistic.

We cant say yes to every request.

If we did, we would fail or go crazy for sure.

Sometimes we simply dont have the time to help.

In this case, we must know how to say no politely.

When we need to say no, here is one method we can try.

First, we should tell the truth.

If we really cant do something, we should just say so.

Second, we should remember to refuse requests politely.

We must communicate clearly, but must also be sincere and sympathetic.

A true friend will understand.

Finally, we must not feel guilty about saying no.

Sometimes refusing others is the right thing to do.

It can save ourselves, and them, a lot of trouble.

In short, we cannot please everyone all the time.

Refusing favors is a part of life.

Good morning, ladies and gentlemen!

I’m honored to share my feelings with you about Beijing Olympic games. The title of the speech is: A Scene to look forward I would like to begin with a story.

There was an elder who traveled all around the world to introduce China for bidding Olympic games. That special hard experience had rooted in his mind. After hearing the good news that China succeeded in the bid for hosting the 29th Olympic Games, he was so excited that he could not stop shedding tears, saying I had been waiting for the day since 1993, the happiest thing finally happened to China. The man is Mr. HeZhenliang, who has devoted his rest life to Chinese Olympic Games. It is with his spirit, passion, courage and strong sense of patriotism to China that we are taking our next step into the world.

Ladies and gentlemen, now I have a question for all of you who are sitting here. Do you still remember that memorable scene? Yes or no? Please put out your hands, let me see how many? Wow, a lot of people. The unforgettable moment is still lingering in your mind clearly.

At 10:08 P.M. on July 13th, 20XX, Mr. Samaranch, the former President of the International Olympic Committee, announced in Moscow that the sponsoring city of the 29th Olympiad will be the city of Beijing. Just at the same time in China, the excitement rippled through the Olympic conference room into Beijing, into the city and into the whole nation. The Chinese, abroad or at home, celebrated the successful great moment in various ways, like hugging each other, jumping, yelling, crying, drinking, singing, dancing and parading on the streets in the midnight. Modern China, a product of 5000 years of civilization and history, with her spirit of hard work and perseverance, finally shook hands with the Olympic games, fulfilling the long expected dream.

Now many Chinese are trying their best to do what they can do for the upcoming games. They learn English to communicate with foreigners. They get rid of bad habits to protect environments. They are eager to be volunteers to serve the Olympic Games. They introduce great Chinese tradition, culture and civilization to the world people. They apply for the torchbearers to carry on the message “share the peace, share the Olympics”.

At the moment when one-year countdown has marked, our Chinese people are getting ready for this big event. The Beijing Olympic committee organization is keeping the promise made in the bid. Under the guidance of the concept of the green Olympic, the tech-Olympic and the people’s Olympic, the 29th Olympic games will strengthen the communication, enhance the cooperation, and shorten the distance between China and the world.

Once again, I want to emphasize one point “national participation”. Like us, a common citizen, we strongly realize the responsibility of our own: planting more trees to cover the space, driving less to relieve the traffic jam, making full use of energy to reduce the pollution and so on. All these actions will not only improve our living environments, but also benefit our coming generation.

Next year in August 8th, Beijing will witness the world’s greatest sporting event, will bring Olympic values to one-fifth of the world’s population, will be one of the most exciting projects in Olympic history. Beijing, a main attraction to tourists, will stretch hands to give the world people a warm welcome, and all the guests will be impressed deeply by China’s state-of-the-art venues, comfortable city environments, enthusiastic volunteers and overwhelming public interest.

No matter who we are, what we do, where we go, in our mind, there’s always a scene to look forward, a scene worth our effort to wait for.

Thank you very much!

Good afternoon ,ladies and gentlemen!

I’m very honored to stand here and give you a short speech! my topic is Opportunities and Challenges.

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 2008 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, 2008 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.

I thank you!

主题明确，逻辑清楚，过度自然，注重互动，开头提问，抑扬顿挫，语言流畅—— 用英文做好PPT展示，我想这些是基本的元素。 但从PPT本身来看，图文并茂，语言简洁，是基本要求。 如果再要求高一些，我想用的图和主题以及所讲的内容完全符合，并能很好地衬托出主题至关重要。从图的清晰程度而言， 我一般选用高清的大图，这个图一定是有故事的，甚至不用语言，观众一看就能产生联想，那么这张PPT基本成功了，再加上简洁的语言，则显得更有张力。 PPT切忌大段的文字，特别是演讲类的PPT，则更不能放太多文字。 PPT整体的逻辑性也很关键。每一张漂亮的PPT如果没有有效地联系起来，那么就容易让观众糊涂。PPT本身的逻辑关联很重要。 PPT预演很重要。在正式讲之前，一定要反复多练习几次。其实在一遍一遍彩排的时候，也是不断发现问题，不断完善的时候，自然也是熟悉PPT的时候。因此很多遍练习之后，在正式演讲时，对PPT的把控和解读会游刃有余。 解读PPT，而不是照着PPT念。PPT充其量就是一个工具，不能因为这个工具影响了演讲本身，与其那样，不如不做PP。
