Essay 1 What is logistics？

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 valuable 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 cormmercial transaction.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 completed,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 facilities and equipment,such as ports,warehouses and trucks,ships,railroad,cars and airlines.By software,we mean information system,standardization and datasharing.

An access control mechanism（71）between a user(or a process executing on behalf of a user)and system resources,such as applications,operating systems,firewalls,routers,files,and databases.The system must first authenticate（验证）a user seeking access.Typically the authentication function determines whether the user is（72）to access the system at all.Then the access control function determines if the specific requested access by this user is permitted.A security administrator maintains an authorization database that specifies what type of access to which resources is allowed for this user.The access control function consults this database to determine whether to（73）access.An auditing function monitors and keeps a record of user accesses to system resources.
In practice,a number of（74）may cooperatively share the access control function.All operating systems have at least a rudimentary（基本的）,and in many cases a quite robust,access control component.Add-on security packages can add to the（75）access control capabilities of the OS.Particular applications or utilities,such as a database management system,also incorporate access control functions.External devices,such as firewalls,can also provide access control services.
A.cooperates
B.coordinates

The brain is a seemingly endless library, whose shelves house our most precious memories as well as our lifetime’s knowledge. But is there a point where it reaches capacity. The answer is no, because brains are more sophisticated than that. Instead of just crowding in, old information is sometimes pushed out of the brain for new memories to form. Precious behavioral studies have shown that learning new information can lead to forgetting. But in a new study, researchers demonstrated for the first time how this effect occurs in the brain. In daily life, forgetting actually has clear advantages. Imagine, for instance, that just lost your bank card. The new card you receive will come with a new personal identification number(PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to the relevant information, without old memories interfering. And most of us may sometimes feel the frustration of having old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory (where you are trying to remember new, but similar information) is particularly vulnerable to interference. When we acquire new information, the main automatically tries to incorporate(合并) it within existing information by forming associations. And when we retrieve(检索) information, both the desired and associated but irrelevant information is recalled. The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to place greater emphasis on the conditions under which we forget, and its importance begins to be more appreciated. A very small number of people are able to remember almost every detail of their life. While it may sound like an advantage to many, people with this rare condition often find their unusual ability burdensome. In a sense, forgetting is our brain’s way of sorting memories, so the most relevant memories are ready for retrieval. Normal forgetting may even be a safety mechanism to ensure our brain doesn’t become too full. What does the passage say about forgetting？
A、It can enlarge our brain capacity.
B、It helps get rid of negative memories.
C、It is a way of organizing our memories.
D、It should not cause any alarm in any way.
