    Brown cows may not actually make chocolate milk, but pink silkworms (蚕) do produce pink silk, a team of scientists has discovered. To see if they could produce pre­dyed silk—silk that comes colored, straight from the source—the team fed ordinary silkworms mulberry (桑树) leaves that had been sprayed (喷洒) with fabric (织物) dyes (染色剂). Out of seven tested dyes, only one worked, producing a thread that reminded me of pink­dyed hair.

    And yes, the worms themselves take on some color before they produce silk.  Their colorful diets did not affect their growth, the team, which included engineers and biologists from the CSIR­National Chemical Laboratory in India, reports in the journal ACS Sustainable Chemistry & Engineering. (The researchers didn't look too deeply into how the dyes affected the silkworms' health. After all, silkworms die when people harvest their silk.

    The team made dyeing silk this way because coloring fabric normally uses large amounts of fresh water. The water gets polluted with dangerous chemicals in the process, requiring costly treatment before factories can send it back into waterways.  Dyeing silk directly by feeding silkworms would avoid those water­washing steps.  Scientists are just starting to study this idea.  However, it remains to be seen if it's commercially successful.  In this experiment, the Indian team tested seven dyes, which are cheap and popular in the industry.

    The scientists found different dyes moved through silkworms' bodies differently. Some never made it into the worms' silk at all. Others colored the worms and their silk, but the color disappears before the silk is turned into fabric. Only one dye, named “direct acid fast red”， showed up in the final, washed silk threads.  By the time it made it there, it was a pleasant, light pink.

The text is most probably a(n) ________.

    One new discovery after another has been over and over again plunging a hard-to-accept idea into scientists’ minds: there might have been an even more advanced super prehistoric civilization in the remote past. 

    Discovery One: Kept in Topkapi Palace, Istanbul, Turkey is a unique ancient map, which was first discovered in the 18th century. On the map, only the Mediterranean area is accurately mapped while other places, such as America and Africa, are well out of shape. When studying in a deeper way, however, the scientists were amazed at finding the ancient map was actually a bird’s-eye map. Compared with the pictures of the earth taken by the Apollo 8 spacecraft, the Turkey map is exactly the repeat of them and the deformable boundaries of America and Africa agree well with those of the Apollo 8’s pictures. To scientists’ astonishment, the map even describes the complex landforms of the Antarctic covered with several-kilometer- thick ice, which is as like as two peas with the map made by the 1952 Antarctica expedition with the help of the sonic echo sounder. But the old map was made in the remote ancient times!

    Discovery Two: On the Lake Titicaca Plateau of South America lies the ruin of an ancient city, at the centre of which stands a huge red sandstone statue. Printed on it is a complete star map with hundreds of signs. Through years of study, scientists finally decoded the map and signs. This is a star map describing the starry sky 27,000 years ago. The signs record the extremely deep astronomic knowledge, which is even beyond the modern people’s understanding.

    Discovery Three: In 1921, people happened to find an ancient Nied man’s skull in Zambia, Africa. In the right of the skull there is an edge-smooth round hole, which scientists have decided only a bullet can make. But the ancient Nied people lived about 70,000 years ago, when mankind is supposed to have just learnt to use axes. 

    Was there really a prehistoric super civilization? God knows!

The Turkey map was made in _______.

    About 30 years ago, I left Cuba for the United States with my son. After getting settled finally in Brunswick, New Jersey, I enrolled(注册) my son in kindergarten. Several weeks later, my son’s teacher asked me to meet him at his office.

    In the teacher’s office, and exchange of greetings was followed by his questions: “ Is your son mentally retarded(弱智的)? Does he suffer from any kind of mental disability?”

    Was he talking about my wonderful Scola? No, no, it can’t be. What a helpless, lonely moment! I told him that Scola was a quiet, sweet little boy, instead. I asked him why he was asking me all these questions.

    My son could not follow the teacher’s directions, he told me, and thus, Scola was disrupting the class. Didn’t he know my son did not speak English yet? He was angry: “ Why hasn’t your son been taught to speak English? Don’t you speak English at home?”

    No, I didn’t speak English at home, I replied. I was sure my son would learn English in a couple of months, and I didn’t want him to forget his native language. Well, wrong answer! 

    What kind of person would not speak in English to her son at home and at all times? “ Are you one of those people who come to this country to save dollars and sent them back to their country, never wanting to be a part of this society?”

    Needless to say, I tried to tell him I was not one of “ those people.” Then he told me the meeting was over, and I left.

    As I had expected, my son learned to speak English fluently before the school year was over. He went on to graduate from college and got a job, earning close to six figures. He travels widely and leads a well-adjusted, contented life. And he has benefited from being bilingual(双语的)。

    Speaking more than one language allows people to communicate with others; it teaches people about other cultures and other places- something very basic and obviously lacking in the “educator” I met in New Jersey.

The author’s attitude towards being bilingual may best be described as __________.

    Around 1975 books were written about strange occurrences in the Bermuda Triangle, a part of the Atlantic Ocean off the southeast coast of the U.S. They told the stories of planes and ships that disappeared for no understandable reason and were never found again. They told about ships which were found undamaged but with no one on them. According to the books, more than 1,000 people disappeared in the Triangle from 1945 to 1975.

    According to some writers, there were no natural explanations for many of the disappearances, so they suggested other explanations. For example, some strange and terrible power exists in the Triangle. According to another writer, people from space are living at the bottom of the Atlantic, and sometimes they need human sailors and airmen for their research. These ideas were not scientific, but they were good advertisements. The books about the Bermuda Triangle were immediate successes.

    However, the books give little evidence to support their unusual ideas. In addition, they ignore at least three important facts that suggest natural reasons for many of the occurrences. First, messages from some of the ships and aircraft which later disappeared give us evidence of problems with navigational instruments. Similar stories are told by officers who were on duty on planets and ships which finally managed to come through the Triangle without disaster. Second, the weather in this part of the Atlantic Ocean is very unpredictable. Dangerous storms that can cause problems even for experienced pilots and sailors can begin suddenly and without warning. Finally, the Bermuda Triangle is very large, and many people, both experienced and inexperienced, sail and fly through it. Perhaps the figure of 1,000 deaths in thirty years shocks some people, but, in fact, the figure is not unusual for an area of ocean that is so large and that is crossed by so many ships. 

    The evidence which exists, therefore, supports one conclusion about Bermuda Triangle: We do not need stories about people from space or strange unnatural powers to explain the disappearances.
