Money Matters
Parents should help their children understand money. 61 so you may start talking about money when your child shows an interest in buying things, candy or toys, for example.
1. The basic function of money
Being explaining the basic function of money by showing how people trade money for goods or services. It’s important to show your child how money is traded for the thing he wants to have. If he wants to have a toy, give him the money and let him hand the money to the cashier. 62 when your child grows a bit older and understands the basic function of money, you can start explaining more complex ways of using money.
2. Money lessons
Approach money lessons with openness and honesty. 63 If you must say no to a child’s request to spend money, explain, “You have enough toy trucks for now.” Or, if the request is for many different things, say “You have to make a choice between this toy and that toy.”
3. 64
Begin at the grocery store. Pick out similar brands of a product—a name brand butter and a generic(无商标产品),for example. You can show your child how to make choices between different brands of a product so that you can save money. 65 If he chooses the cheaper brand, allow him to make another purchase with the money saved. Later, you may explain how the more expensive choice leaves less money for other purchases.
A. Wise decision.
B. The value of money.
C. Permit the child why he can—or cannot—have certain things.
D. Talk yourself what things that cost money are most important to you.
E. Ask yourself what things that cost money are most important to you.
F. Talk about how the money bought the thing after you leave the toy store.
G. The best time to teach a child anything about money is when he shows an interest.

With petroleum reserve(石油储量)decreasing, the search is on to replace gas with a cleaner, greener alternative. Though much eco-talk has centered on biofuels from corn and soybeans, the biofuel that looks more likely to replace petroleum comes from a most unlikely source: algae(藻类).
Algae, like corn, soybeans, and other crops, grow via photosynthesis(光合作用)and can be processed into fuel oil. However, they yield 30 times more energy than land crops such as soybeans, according to the U.S. Department of Energy. Many algae species also can grow in saltwater and polluted water—while corn and soy require arable(适于耕种的) land and fresh water that will be in short supply as the world’s population balloons.
“If you replaced all the diesel(柴油)in the U.S. with soy biodiesel, it would take half the land mass of the U.S. to grow those soybeans,” says Matt Caspari, chief executive of Aurora Biofuels, a Berkeley, Calif-based private firm that specializes in algae oil technology. On the other hand, the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States, it would require only l5, 000 square miles, which is a few thousand miles larger than Maryland (12,407 squaree miles), the 42nd state in land area.
Another advantages: Because algae can be grown just about anywhere in a closed space, they’re being tested at several power plants across the nation as a carbon absorber. Smokestack emissions(烟囱排放物)can be pumped directly into the ponds, feeding the algae while keeping greenhouse gases out of the atmosphere.
Although processing technology for algae fuel—also known as “oilgae” in some environmentalist circles —is improving, it’s still years away from reaching your local gas pump. “It’s just a question of cost, because no large-scale facilities have been built yet,” Caspari says.
