The management of logistical (物流的) operation is about movement and storage of materials and finished products. Logistical operations start with the initial shipment of a material or component part from a supplier and are finished when a manufactured or processed product is delivered to a customer.
From the initial purchase of a material or component, the logistical process adds value by moving inventory (移动库存) when and where needed. If all goes well, a material gains value at each step of its transformation into finished inventory. In other words, an individual part has greater value after it is put into a machine. Likewise, the machine has greater value once it is delivered to a buyer.
To support manufacturing, work-in-process inventory must be moved to support final assembly. The cost of each component and its movement becomes part of the value-added process. The final or meaningful value that is added occurs only with final ownership transfer of products to customers when and where specified.
For a large manufacturer, logistical operations may consist of thousands of movements, which finally develop into the delivery of products to an industrial user, retailer, wholesaler, dealer, or other customer. For a large retailer, logistical operations may start with gaining products for resale and may finish with consumer pickup or delivery. For a hospital, logistics starts with purchasing and ends with full support of patient surgery and recovery. The significant point is that regardless of the size and type of enterprise, logistics is essential and requires continuous management attention. For better understanding it is useful to divide logistical operations into three areas: physical distribution, manufacturing support, and procurement(筹措、采购) .
Logistical operations are concerned with______.
A.transfer of materials and finished products
B.manufacturing of materials and finished products
C.inventory of materials and finished products
D.both A and C
Clint was playing a game with a girl. I sat in the corner watching him. I didn't feel that I had whatever it took to get up and mix with others because of my self-esteem problem. Finally I got up the courage to order a drink for him. When he got it, he gave me the most dazzling smile. We spent the rest of the evening talking until I realized that it was almost morning. I figured that he was simply being nice to me because I had bought him a drink, but the very next day he called and told me that he could not stop thinking about me and that he wanted to meet my kids too.
(81) About 3 months later, my divorce was final and Clint sat my boys down and asked them if it was all right with them if he asked me to marry him because he could not imagine life without the three of us anymore. I was so touched that he went to my boys and asked for their approval because they were the "men of the house" at the ripe old ages of 2 and 4. They said yes and we have all been together ever since. Clint gave me and my boys a second chance at a wonderful life. (82) Not a day goes by that he doesn't tell we are the best thing that ever has happened to him and that he loves us.
The writer's first marriage was unsuccessful because______ .
A.her husband often woke her up at midnight
B.her husband kept criticizing her
C.she was unattractive
D.she had a self-esteem problem
It is argued that the type of production method which is employed depends on the development of an individual company. That is to say, many factories begin manufacturing on a job production basis and proceed, as the volume of production increases, to batch and flow production methods. This is not always the case, however, since the type of production is not necessarily determined by the product volume which is aimed at. In fact, in the car industry, tools are produced by jobbing methods, components are produced by batch methods, and the final products are assembled by flow methods.
Flow production is associated with flow layouts, whereas job and batch production are associated with process layouts. In a process layout, machines of a similar type are grouped together in the same section of the factory, and work in progress is moved from one part of the factory to another. In a flow layout scheme, the manufacturing equipment is arranged in the same sequence as the operations performed on the product. Each of these operations must be capable of processing work at the rate required for assembly of the final product, and the output for each operation must be balanced in order to provide a smooth flow of work.
There are advantages in both types of layout. In a process layout system there is more flexibility, and a greater specialization of machines and labor is possible, while in a flow layout system it is not necessary to maintain a high level of stocks or to demand great skill in the workforce.
The production method is not dependent on the size of a company because different products can be______
A.displayed at different locations
B.produced by different production methods
C.designed by different specialists
D.sold at different markets

Stem cells are cells that have not yet decided what they want to be when they grow up. That is, they can become blood cells, brain cells, or pretty much any other type of cell. Their versatility makes them extremely useful for medical research. The ethical snag is that the best stem cells are harvested from human embryos, killing them. For the most ardent pro-lifers, including Mr. Bush and many of his core supporters, that is murder. Proponents of embryonic stem-cell research point out that hordes of embryos are created during fertility treatment, and the vast majority of these are either frozen indefinitely or destroyed. Is it really wrong to use them for potentially life-saving research? Yes, said Mr. Bush on July 19th, flanked by some families who had "adopted" other people's frozen embryos and used them to have children of their own.
Mr. Bush's veto does not kill stem-cell research. Scientists who spurn federal cash may do as they please. The government still pays for research on stem cells taken from adults, a process that does not kill the donor. And a decision by Mr. Bush in 2001 allows federally-funded scientists to experiment on the few dozen embryonic stem-cell "lines" that already existed then, which can be propagated in a laboratory.
Nonetheless, scientists are furious with Mr. Bush. Federal funding would surely push them faster towards those elusive cures. Research based on adult stem cells may be promising, but not nearly as promising as that based on embryonic ones. There are worries that those few dozen embryonic stem-cell lines represent too narrow a gene pool, and that they cannot be endlessly extended without damaging them. Other countries, such as Britain and China, are enthusiastically experimenting on embryonic stem cells. But the world's most innovative nation is hanging back.

Henry Kissinger may be the most successful, certainly the most flamboyant, Secretary of State to hold that office in modern times. When he was appointed in the late 1960's, there were no American ties with Communist China, Vietnam and Berlin seemed ready to draw the United States into a third world war, and Russia was seen as "the enemy".
But all this has changed, and Henry Kissinger caused much of the change; in 1971, he made his first trip to China, a trip that was the beginning of the current ties between the United States and China. He brought the United States and Russia closer together on major issues by the policy he called "detente", literally meaning a relaxation. His philosophy was always to talk and to bring together. With these two policies, Kissinger did much to draw attention away from any possible Russia-American friction.
In 1973 he made his first visit to Egypt. Here he was able to begin U.S. relations with Egypt. He used his contact later to begin the sort of talks that the American press called "shuttle diplomacy". For ninety-nine days, he "shuttled" back and forth on flights between Cairo and Jerusalem to work out a step-by step withdrawal of Israeli troops from the Sinai desert. His wit, his careful approach to detail, and his presence made "shuttle diplomacy" work. It was the only successful approach to Mid-east peace in the thirty years since the state of Israel was founded.
Another major work was the Strategic Arms Limitation Talk. Though his term in office passed with the treaty unsigned, Kissinger left a draft of the treaty to which the Russians had already agreed. The SALT treaty spelled out a one-tenth reduction in nuclear arms, a major accomplishment by any standard, even if one does not consider all the other conditions and limitations included in the treaty.
Even though he successfully helped bring an end to the Vietnam War, Kissinger's final days in office were affected, as was the entire executive branch in one way or another, by the scandals of the Nixon White House. Kissinger's critics point to his role in placing wiretaps on the phones of reporters and officials and to what they consider his "high-handed" approach to setting foreign policy. But Kissinger, during the last few months of the Nixon presidency, limited the effects of American domestic problems on our foreign policy. He continued talks in the Middle East. He continued close contact with the Soviet Union.
History will decide in the final view, as Kissinger—and many presidents—often said, on the value of his service. Whatever they decide, whether his actions are finally to be considered wise or foolish, he had a personal vision that will be difficult to match.

work out 制定
spell out 清楚地说明

First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle.
Next the thinker must define the problem. Before Sam can repair his bicycle, he must find the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific.
Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time. he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully.
After studying the problem; the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels.
Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels.
Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem.
