It is physically impossible for a well-educated, intellectual(理性的), or brave man to make money the chief of his thoughts; as physically impossible as it is for him to make his dinner the principal object of them. All healthy people like their dinner, but their dinner is not the main object of their lives. So all healthy-minded people like making money but the main object of their lives is not money; it is something better than money.
A good soldier, for instance, mainly wishes to do his fighting well. He is glad for his pay very properly so, and justly grumbles (抱怨) when you keep him ten months without it; still his main motion of his life is to win battles, not to be paid for winning them.
So of doctors. They like fees no doubt-ought to like them; yet if they are brave and well-educated, the entire object of their lives is not fees. They, on the whole, desire to cure the sick, and they are good doctors, and the choices were fairly put to them would rather cure their patients and lose their fees than kill him and get it. And so with all other brave and rightly trained men, their work is first, their fee second, very important always, but still second.
The main idea of the text is that _______.
A.people can't live without money.
B.money is as important as work.
C.the main object of the people's lives should not be money but work.
D.the entire object of the people's lives is making money.

That industry is based on biotechnology. At the moment, biotech's main uses are in medicine and agriculture. But its biggest long-term impact may be industrial. Here, it will diminish demand for oil by taking the cheapest raw materials imaginable, carbon dioxide and water, and using them to make fuel and plastics.
Plastics and fuels made in this way would have several advantages. They could accurately be called "renewables", since nothing is depleted to make them. They would be part of the natural carbon cycle, borrowing that element from the atmosphere for a few months, and returning it when they were burned or dumped. That means they could not possibly contribute to global warming. And they would be environmentally friendly in other ways. Bioplastics are biodegradable, since bacteria understand their chemistry and can therefore digest them. Biofuels, while not quite "zero emission" from the exhaust pipe (though a lot cleaner than petrol and diesel), would be cleaner overall even than the fuel-cell technology now being touted as an alternative to the internal-combustion engine. That is because making the hydrogen that fuel cells use is not an environmentally friendly process, and never will be—unless it, too, uses biotechnology.
All this will, in the end, depend on costs. But these do not look unfavourable. Already, the price of bioplastics overlaps the top end of the petroleum-based plastics market. Bulk production should bring prices 'down, particularly when the raw materials are free. Meanwhile, ethanol would be a lot easier to introduce than fuel cells. Existing engines will run on it with minor tweaking, so there is no need to change the way ears are made. And since, unlike hydrogen, it is a liquid, the fuel-distribution infrastructure would not need radical change.
The future could be green in ways that traditional environmentalists had not expected. Whether they will embrace that possibility, or stick to sack-cloth, remains to be seen.

A.has brought about sustainable development.
B.proves to be nothing but an imagination.
