　　(2016·郑州适应性测试)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 CSIR—National 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.

　　【答案】　1－4　ADBA

　　2．Silkworms can produce pink silk because ________.

　　A．they are born pink

　　B．they are dyed pink

　　C．they grow in pink water

　　D．they are fed dyed food

　　【答案】　D
