A wise man was walking from one town to another with a few of his followers, and they happened to pass a lake. So they stopped there to   1  for a while, and the wise man said to one of his followers, “I am very  2 . Could you please  3  me some water from the lake?”

After they had rested for about half an hour, the wise man again asked the   7  follower to go back to the lake and get him some water to drink. As requested, the follower went to the lake. This time he found that all the mud had   8   to the bottom. The water was very   9 and looked fit to drink. So he    10 his water bottle and took it to the wise man.

The wise man took the water bottle and drank, then looked up at the follower. “See what you did   11   the water clean?” he said. “You let it be for a while and the mud settled down on its own,  12  you could get some clear drinking water.

Rent(出租)a room
Spare room? Not only will a lodger (房客) earn you some money, but also, thanks to the government-backed “rent a room” program, you won’t have to pay any tax (税) on the first ￡4,500 you make per year. Try advertising your room on Roomspare or Roommateeasy.
Make money during special events
Don’t want a full-time lodger? Then rent on a short-term basis (基础). If you live in the capital, renting a room out during the Olympics or other big events could bring in money. Grashpadder can advertise your space.
Use your roof (屋顶)
You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment (around￡14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier (供应商), which could prevent you from changing the roof. 
【小题1】If you earn ￡5,000 from renting a room in one year, the tax you need to pay will be based on ________.

For thousands of years, people have used plants to make medicines. They used different parts of the plants —the roots, the leaves, the flowers, and the bark (树皮). Today, doctors have rediscovered more medicinal (药用) values of some plants. Let’s look at some examples.
Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems.
In some areas, malaria has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria.
In Germany, some scientists studied garlic (大蒜) for four years. They found that it helps prevent the build-up of plaque (血小板) because too much plaque is bad for health. This very common plant continues to be studied.
As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent.
