恒发公司与如意服装厂签订了一份服装买卖合同，合同标的额为80万元。双方在合同中约定：恒发公司预付定金10万元，如任何一方不履行合同应支付违约金15万元。合同签订后，恒发公司积极筹措资金并向如意服装厂支付了10万元定金。恒发公司以自己所有的一辆宝马车(价值50万元)做抵押向 A银行贷款35万元，双方还约定如恒发公司到期不能还款，则这辆宝马车就归A银行所有。恒发公司认为办理抵押登记太麻烦，于是经A银行同意，双方签订贷款及抵押合同后就未向有关机关办理抵押登记。其后，恒发公司又以这辆宝马车做质押向B银行贷款20万元，双方签订了贷款及质押合同。在质押期间，B银行董事长李某开着质押的宝马车与他人相撞，汽车修好后，李某拿着3万元去提车。修理厂收钱以后要求李某把B银行以前的欠款2万元还清，李某不愿归还，于是修理厂就以行使留置权为名拒绝向李某交车。 问题：

The market is a concept. If you are growing tomatoes in your backyard for sale you are producing for the market. You might sell some to your neighbour and some to the manager of the local supermarket. But in either case, you are producing for the market. Your efforts are being directed by the market. If people stop buying tomatoes, you will stop producing them.

If you take care of a sick person to earn money, you are producing for the market. If your father is a steelworker or a taxi driver or a doctor or a grocer(杂货商), he is producing goods or service for the market.

When you spend your income, you are buying things from the market. Yon may spend money in stores, supermarkets and gas stations. Still you are buying from the market. When the local grocer hires you to drive the delivery truck, he is buying your labor in the labour market.

The market may seem to be something abstract(抽象的). But for each person or businessman who is making and selling something, it is real. If nobody buys your tomatoes, it won’t be long before you get the message. The market is telling you something. It’s telling you that you are using energies and resources in doing something the market doesn’t want you to do.
