Inventory
Inventory is an important part of the cost of doing business in a large company. If a company is assembling cars, they must have a large number of parts in hand so that the assembly line does not stop because one part is missing. If cars are going down the assembly line and one person is supposed to fasten wheels on to the car, the whole line will stop if he runs out of fasteners. This means that several hundred men will be waiting while someone must find fasteners for the wheel. So there must be a sufficient number of parts of all sorts nearby in order to keep the car assembly line running smoothly.
A large supply of spare parts is very expensive, so a company will try to keep its inventory as low as it can without finding it necessary to stop production for lack of a part.
In a planned company, it was often difficult to secure spare parts and so many companies ordered many extra parts and kept large supplies of
A. will try to keep as many as it can

[单项选择] If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.
If you say to your children “I’’m sorry I got angry with you, but …” what follows that “but” can render the apology ineffective: “I had a bad day” or “your noise was giving me a headache” leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology.

A. You have good reason to get upset
B. I’’m aware you’’re upset ,but I’’m not to blame
C. I apologize for hurting your feelings
D. I’’m at fault for making you upset
