Dye (染料) can bring a little color to life. Most clothing is colored with dyes. Modern, manufactured dyes can be costly. Natural dyes from plant and animal products have been used since ancient times. So this week, we describe a natural way to dye wool.
There are several methods to put dye onto material. The vat method, for example, can be used to dye wool with onionskins. For this example, use one hundred grams of natural wool. 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. Wool ash is one example. But chemical mordants such as alum 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 color, 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 color. 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.
57. 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
58. Which of the following statements about “natural dyes” is true?
A. They might be cheaper than chemical dyes.
B. They are more expensive than chemical dyes.
C. They have been used for only recent years.
D. They are all made from animal products.

A. Ash. B. Water. C. Mordant. D. Temperature.
60. Choose the proper order of dying wool:
a. boil the liquid with onionskins.

It was not until 1978 when Guo Fenglian, head of the village, paid a visit to the US that China"s model village found how far it had fallen behind those in developed countries.
"I was astonished at their modern equipment in harvesting, which could even separate big tomatoes with small ones," said Guo. "American farmers" life quality also impressed me a lot. Every day they had two cups of milk, which is something we don"t have even in our wildest dreams."
"We have to learn their advanced technology and administration for our own development," said then first Deputy Prime Minister Deng Xiaoping who was planning China"s reform and opening up policy then. "Through opening our doors, we would not only take advantage of foreign funds (资金), but also create job opportunities and cultivate (培养) talents."
In 1978 Japanese electricity giant Panasonic (松下) came to China as the first foreign business to invest (投资) here and its success attracted other world brands into exploring the Chinese market. So far China has for 15 years taken in the world"s second biggest foreign investment, following the US, to help set the country in a fast growth.
However, China"s 30-year road of reform was not always smooth. Doubts on the reform began to rise at the end of the 1980s as many people worried the country would turn to capitalism (资本主义).
"The criterion for our judgment is whether it helps develop socialist productive forces, whether it helps increase the overall national strength of a socialist country, and whether it brings about better living standards," said Deng.
"China"s reform and opening up is a unique success story. It has brought benefit to both China and the world," said William Keller, chief manager of a Swiss pharmaceutical (制药的) company.
小题1:Guo Fenglian was ______ at the sight of the modern equipment in harvesting when she visited the US in 1978.
A.shocked | B.delighted | C.excited | D.attracted |
A.America | B.Japan | C.Swiss | D.Panasonic |
A.in 1978 | B.in 1980 |
C.in 1981 | D.at the end of the 1980s |
A.whether it helps develop socialist productive forces. |
B.whether it strengthens the overall capacity of the country. |
C.whether it brings about better investment and more profit. |
D.whether it improves the peoples living standards. |
Last week, British newspapers reported that the England national team had been secretly recorded by an unknown group of individuals.
Media suggested that bugs had picked up a discussion of team tactics (战术), as well as playful talk about athletes’ affairs and possible rewards for players if they manage to win the World Cup.
England officials immediately filed a suit to stop media from publishing the contents of the recordings. Little is known about the identities of the spies, but authorities doubt they have any connection to rival sides preparing for this summer’s competition in South Africa. Rather, it appears that the people who bugged the hotel meeting room are just after money. If they find the right buyer, they could get a lot of it.
Gambling in major sports, like football, involves much more than picking the winner of a particular match. People can also place bets on starting line-ups, the timing of substitutions and goals scored. Knowing a team’s tactics for a particular game, or for a series of games, can help gamblers to increase their chances of winning big money.
England manager Fabio Capello tried to play down the importance of game tactics. He argued that a team’s psychological preparation is the most vital. “It’s more important to train the mind, to find confidence, create a group and a winning mentality,” he said.
Perhaps of more interest to the casual fan are the discussions of the players’ relationships with wives and girlfriends. UK newspapers may be prevented from publishing the details, but some Britons might say, the chances of the recordings never being heard are about as good as those of England winning this year’s competition: slim to none.
小题1:We may know from the first paragraph that ______________.
A.the spies mentioned are all pursuing money |
B.all the spies are employed by the government |
C.James Bond belongs to spies of the business world |
D.if a sport spy can find a buyer, he can make money |
A.A small insect. | B.The devices used in the spying. |
C.A kind of virus. | D.A kind of laptop computers. |
A.are from the rival sides for sure |
B.probably intended to make money |
C.are involved in gambling |
D.knew a winning mentality for a team is important |
A.The chance of the England team winning the African World Cup is very small. |
B.Many people will never hear the recordings. |
C.A fan will be more interested in the players’ relationships with wives and girlfriends. |
D.No one can get any information from the UK newspapers for ever. |

There are two ways in which one can own a book. The first is the property (财产) right you have by paying for it, just as you pay for clothes and furniture. While full ownership comes only when you have made it a part of yourself and the best way to make yourself a part of it is by writing marks on it.
Why is marking up a book indispensable to reading? First, it keeps you awake. Second, active reading is thinking, and thinking tends to express itself in words. Finally, marking helps you remember the thoughts you had, or the thoughts the author expressed.
Reading a book should be like making a conversation, a conversation between you and the author. Although he knows more about the subject than you do, don’t let anybody tell you that a reader is only on the receiving end. Understanding is a two-way operation. Reading doesn’t mean being a passive empty receiver, the reader has to question himself and question the author. And marking a book can show his own judgment on author’s opinion: agreement or difference.
小题1:The author thinks “marking between the lines” is ______.
A.the most important of all |
B.more important than “reading between the lines” |
C.as important as “reading between the lines” |
D.not so important as “reading between the lines” |
A.to absorb its content and make it a part of yourself |
B.to have property right by paying for it |
C.to write many words of sentences on it |
D.to make a conversation with the author |
A.troublesome | B.difficult | C.useless | D.necessary |
A.a reader will receive everything the book presents |
B.the author should understand readers |
C.a reader should have his own judgment of the author’s opinion |
D.the author should help readers understand better |
A.How to Own a Book | B.Mark Between the Lines |
C.How to Understand Author | D.Read Between the Lines |
The study by Queensland University’s Center for Marine Studies, commissioned (委托) by the Worldwide Fund for Nature, said that the destruction of coral on the Great Barrier Reef was unavoidable due to global warming, regardless of what actions were taken now. “Under the worst-case scenario, coral populations will collapse by 2100 and the reestablishment of coral reefs will be highly unlikely over the following 200-500 years,” said the report entitled “Implications (可能的影响) of Climate Change for Australia’s Great Barrier Reef.”
The Great Barrier Reef is the world’s largest living reef formation stretching 2,000 km north to south along Australia’s northeast coast. “Only if global average temperature change is kept to below two degrees Celsius can the Reef have any change of recovering from the predicted damage,” the report said. Coral has a narrow comfort zone and is highly stressed by a temperature rise of less than one degree Celsius. Water temperature rises of less than one degree coincided (同时发生) with the world’s worst recorded coral bleaching (颜色变淡) period in 1988. The warmer water forces out the algae (海藻) that give coral its color and, if all are lost, the coral dies and the reef will die out. In 1988, 16 percent of the world’s coral died, with 46 percent of the Indian Ocean coral destroyed.
Scientists express water temperatures to rise this century by between two and six degrees Celsius. “There is little to no evidence that corals can adapt fast enough to match even the lower temperature rise,” said the report. Over-fishing and pollution from coastal farms were also contributing to the destruction of coral on the Great Barrier Reef.
The Great Barrier Reef supports huge fishing and tourism industries. Even under favorable conditions tourists would only be able to experience real corals in reef “theme parks”.
小题1:The underlined word “scenario” in Paragraph 2 probably means .
A.imagination | B.intention | C.expectation | D.prediction |
A.corals have no difficulty in adapting the temperature change |
B.if we take quick actions we can avoid the destruction of corals |
C.we can find corals in many areas of the seas or oceans |
D.the algae help corals to live |
A.Direct sunshine. | B.Over-fishing. |
C.Global warming. | D.Pollution. |
A.coral can only live in a small area |
B.coral prefers a crowded place |
C.coral can hardly adapt to the temperature change |
D.coral grows best in a small area |
