         Dye (染料) call bring a little colour to life. Most clothing is coloured with dyes. Modern，manufactured dyes can be costly. Natural dyes from plant and animal products have been used since ancient times. Here we describe a natural way to dye wool.

        There are several methods to put dye onto material. The vat（缸）method，for example，can be used to dye wool with onionskins. For this example，use one hundred grams of natural woo1. The wool must be clean. Leave it overnight in water and liquid soap. Then wash it with clean water that is a little warm. Gently squeeze out the extra water.   

       A solution called a mordant (媒染) is used in the dying process. A mordant helps fix the dye to the material. Traditionally, mordants were found in nature. Wood ash is one example. But chemical mordants such as alum（矾）are popular today. Alum is sold in many stores. It is often mixed with cream of tartar, a fine powder commonly used in cooking.

       Mix eight grams of alum with seven grams of cream of tartar in a small amount of hot water. Add the solution to a metal pan of cool water. Next, add the wool and place the mixture over heat. Slowly bring the liquid to eighty-two degrees Celsius. Heat the mixture for forty five minutes. After it cools, remove the wool and wash it.

       To prepare the dye solution, cover thirty grams of onionskins with water. Use only the dry，brown outer skins. Boil the liquid until the onionskins lose their colour, about forty—five minutes. Remove the skins after the dye cools.

    Now it is time to dye the wool. Place the wool into the dye and heat the mixture. Bring it to a boil，then immediately reduce the heat to eighty-two degrees. Now heat the dye for about forty-five minutes or until the wool is the desired colour. Keep in mind that wet wool looks darker than it is.

       Once the dye cools, remove the wool and wash it. Now the wool is orange or yellow. Or at least it should be.

1. According to the passage, mordants are ___________.

       A. dyes used in the dying process   B. materials which will be put dye to

       C. wood ashes used in the dying process       D. not dyes but play an important role in the dying process

.Can you imagine your doctor warning that taking a bath could be unhealthy? In the early 1800s, many doctors thought that bathtubs(浴缸) could carry diseases, so they advised against their use. The advice wasn’t based on personal experience, because few of the doctors owned bathtubs. The White House did not even have a bathtub until 1851.

In the 19th century, only one home out of six had a bathroom. A child took only one bath a week. On Saturday nights, children all lined up for their turns to wash in a wooden bathtub in the kitchen. Mothers had to boil the water on the stove and carry it over to fill the bathtub. It’s no wonder that children could not jump into a bathtub as they do today.

When the first bathtubs were introduced, even their makers weren’t sure whether the new fashion would last. They advertised their products as water containers that “could be used as bathing tubs”.

The bathtub became popular in America shortly after World War I. By then most middle-class families had indoor taps. At first most bathtubs were made of wood, but as the popularity of the product increased, so did the creativity of bathtub makers. Before porcelain(瓷) bathtubs there were rubber ones like the plastic swimming pools kids use today. In the past few years owners often invited guests to see them. They told their friends how wonderful baths in these bathtubs could be.

Now doctors no longer warn that bathtubs carry diseases. Instead, they tell their patients about the benefits of frequent bathing in the bathtubs. Maybe one of the best reasons why doctors encourage frequent trips to the bathtub is that bathed patients smell better!

47. Many doctors in the past were against using bathtubs because ______.

A. they didn’t have their own bathtubs

B. they thought bathtubs could carry diseases.

C. the children might hurt themselves in the bathtubs

D. bathtubs were too expensive for the common families

48. Why couldn’t children jump into a tub in the 19th century as they do today?

A. It was unhealthy to do so.      B. The bathtubs were not enough.

C. Mothers were always busy.     D. The bathtubs were made of wood.

49. Which of the following is true according to the text?

A. Some different materials can be used to make bathtubs.

B. In the 19th century only one home out of seven had a bathroom.

C. The bathtub became popular when they were introduced to the market.

D. Children prefer the bathtubs made of plastic to those made of porcelain.

50. It can be inferred from the last paragraph that ______.

A. all the doctors have bathtubs in their homes

B. the doctors have realized the advantages of bathtubs

C. the doctors will make lots of money by advertising bathtubs

D. the patients should take a bath before going to see a doctor
