What is logistics? In the current business environment,logistics is generally accepted as a very important element for the economic development and business growth of a region,especially a port city. In reality,what does logistics mean?In which way does it operate? For simple definition,logistics is a set of procedures in which commodity is delivered in an efficient manner from suppliers to customers.There are three key aspects to the concepts: 1．Movement of goods Goods can be considered as valuable objects,such as cargo and materials that are valua-ble and purchasable through commercial transactions and processes.Flow can be determined as methods in which goods are moved or transferred between locations,intermediaries and merchandisers.Modes of transportation include motor,rail,water,air and pipeline. 2.Direction of the flow of goods In the open market place,buyers and sellers represent two ends of a commercialtrans-action.Buyers are usually customers who demand the goods,while,as sellers are suppliers who provide such goods.When a transaction is agreed upon (sometimes payment is comple-ted,other times the payment is arranged to be completed at a later stage),the suppliers have the responsibility to arrange for the goods to be delivered to the customers. 3.Efficient management of the flow process The transportation of goods should bear low cost and ensure safety and punctuality.It should do its best to avoid wasting customers＇resources.Currently,the flow of goods is generally controlled by both hardware and software.By hardware,we mean logistics facili-ties and equipment,such as ports,warehouses and trucks,ships,railroad,cars and air-lines.By software,we mean information system,standardization and data sharing.Questions:

Do animals have fights This is how the question is usually put. It sounds like a useful, ground - clearing way to start. Actually, it isn’ t, because it assumes that there is an agreed account of human rights, which is something the world does not have.
On one view of rights, to be sure, it necessarily follows that animals have none. Some philosophers argue that rights exist only within a social contract, as part of an exchange of duties and entitlements. Therefore, animals cannot have rights. The idea of punishing a tiger that kills somebody is absurd, for exactly the same reason, so is the idea that tigers have fights. However, this is only one account, and by no means an uncontested one. It defiles tights not only to animals but also to some people--for instance, to infants, the mentally incapable and future generations, In addition, it is unclear what force a contract can have for people who never consented to it: how do you reply to some body who says" I don’ t like this contract"
The point is this: without agreement on the rights of people, arguing about the rights of animals is fruitless. It leads the discussion to extremes at the outset: it invites you to think that animals should be treated either with the consideration humans extend to other humans, or with no consideration at all. This is a false choice. Better to start with another, more fundamental question: is the way we treat animals a moral issue at all
Many deny it. Arguing from the view that humans are different from animals in every relevant respect, extremists of this kind think that animals lie outside the area of moral choice. Any regard for the suffering of animals is seen as a mistake--a sentimental displacement of feeling that should properly be directed to other humans.
This view, which holds that torturing a monkey is morally equivalent to chopping wood, may seem bravely "logical". In fact it is simply shallow: the confused center is right to reject it. The most elementary form of moral reasoning--the ethical equivalent of learning to crawl--is to weigh others’ interests against one’ s own. This in turn requires sympathy and imagination: without which there is no capacity for moral thought. To see an animal in pain is enough, for most, to engage sympathy. When that happens, it is not a mistake: it is man kind’ s instinct for moral reasoning in action, an instinct that should be encouraged rather than laughed at.

A:is useful and ground- clearing B:should be based upon an agreed account of human rights C:is easy to carry on D:should be the same as that of human rights
