It should go without saying that the focus of UML is modeling. However, what that means, exactly, can be an open-ended question. (71) is a means to capture ideas, relationships, decisions, and requirements in a well-defined notation that can be applied to many different domains. Modeling not only means different things to different people, but also it can use different pieces of UML depending on what you are trying to convey. In general, a UML model is made up of one or more (72) . A diagram graphically represents things, and the relationships between these things. These (73) can be representations of real-world objects, pure software constructs, or a description of the behavior of some other objects. It is common for an individual thing to show up on multiple diagrams; each diagram represents a particular interest, or view, of the thing being modeled. UML 2.0 divides diagrams into two categories: structural diagrams and behavioral diagrams. (74) are used to capture the physical organization of the things in your system, i. e. , how one object relates to another. (75) focus on the behavior of elements in a system. For example, you can use behavioral diagrams to capture requirements, operations, and internal state changes for elements.

Advertisers tend to think big and perhaps this is why they’re always coming in for criticism. Their! critics seem to resent them because they have a flair for self-promotion and because they have so much money to throw around. "It’s iniquitous," they say, "that this entirely unproductive industry (if we can call it that) should absorb millions of pounds each year. It only goes to show how much profit the big companies are making. Why don’t theystop advertising and reduce the price of their goods After all, it’s the consumer who pays ... ".

The poor old consumer! He’d have to pay a great deal more if advertising didn’t create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledge we have about household goods derives largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of the ones we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc, from an advertisement.

Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway by laws while waiting for a train Would you like to read only closely printed columns of news in your daily paper A cheerful, witty advertisement makes such a difference to a drab wall or a newspaper full of the daily ration of calamities.

We must not forget, either, that advertising makes a positive contribution to our pockets. Newspapers, commercial radio and television companies could not subsist without this source of revenue. The fact that we pay so little for our daily paper, or can enjoy so many broadcast programs is due entirely to the money spent by advertisers. Just think what a newspaper would cost if we had to pay its full price!

Another thing we mustn’t forget is the "small ads. " which are in virtually every newspaper and magazine. What a tremendously useful service they perform for the community!Just about anything can be accomplished through these columns. For instance, you can find a job, buy or sell a house, announce a birth, marriage or death in what used to be called the" hatch, match and dispatch" column but by far the most fascinating section is the personal or "agony" column. No other item in a newspaper provides such entertaining reading or offers such a deep insight into human nature. It’s the best advertisement for advertising there is!

The police fired tear gas and arrested more than 5,000 passively resisting protestors Friday in an attempt to break up the largest antinuclear demonstration ever staged in the United States. More than 135,000 demonstrators confronted the police on the construction site of a1,000-megawatt nuclear power plant scheduled to provide power to most of Southern New Hampshire. Organizers of the huge demonstration said that the protest was continuing despite the police actions. More demonstrators were arriving to keep up the pressure on state authorities to cancel the project. The demonstrator had charged that the project was unsafe in the densely populated area, would create thermal pollution in the bay, and had no acceptable means for disposing of its radioactive wasters. The demonstrations would go on until the jails and the courts were so overloaded that the state judicial system would collapse.

Governor Stanforth Thumper insisted that there would be no reconsideration of the power project and no delay in its construction set for completion in three years. "This project will begin on time and the people of this state will begin to receive its benefits on schedule. Those who break the law in misguided attempts to sabotage the project will be dealt with according to the law," he said. And the police called in reinforcements from all over the state to handle the disturbances.

The protests began before dawn Friday when several thousand demonstrators broke through the police lines around the cordoned-off construction site. They carried placards that read "No Nukes is Good Nukes," "Sunpower, Not Nuclear Power," and "Stop Private Prof-its from Public Peril. " They defied police order to move from the area. Tear gas canisters fired by the police failed to dislodge the protestors who had been prepared with their own gas masks or facecloths. Finally the gas-masked and helmeted police charged into the crowd to drag off the demonstrators one by one. The protestors did not resist the police, but refused to walk away under their own power. Those arrested would be charged with unlawful assembly, trespassing, and disturbing the peace.

 

When I opened the first "Body Shop" in 1976, what I wanted to do was to earn(挣) enough money to feed my children. Today the "Body Shop" is a great company growing fast all around the world. In the years since we began, I have learned a lot. Much of what I have learned will be found in this book, because I believe that we, as a company, have something worth saying about how to run a successful business without giving up what you really believe in.

It’s not an ordinary business book. It is not just about my life, either. The message is that to succeed in business you have to be different. Business can be fun, and can be run with love and do good. In business, as in life, I need to enjoy myself, to have a feeling of my family and to feel excited by something unusual. I have always wanted the people who work for the "Body Shop" to feel the same way.

Now this book sends these ideas out into the world, and makes them public. I’d like to think there are no limits(界限) to our "family", and no limits to what can be done. I find that an exciting thought. I hope you do, too.

 

At a certain time in our lives we consider every place as the possible site(地点) for a house. I have thus searched the country within a dozen miles of where I live. In imagination Ihave bought all the farms, one after another, and I knew their prices.

The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the additional dollars and sold him the farm for just what I had given for it.

The real attractions of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相邻) on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.

I was not really troubled by the loss. I had always had a garden,but I don’t think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted(不受约束的). It makes but little difference whether you own a farm or not.
