Many people don't consider their breakfast without a glass of milk. Right now, cows, buffalos, goats and sheep provide most of the world's milk. But soon, people could get milk from roaches(蟑螂).
That isn't as crazy as it might sound. New research shows this "milk" is super﹣nutritious. What's more, some scientists have already begun referring to a lot of insects as source of milk.
In 2004, Subramanian Ramaswamy started studying milk crystals found inside the roach. At the time, he was teaching biochemistry at the University of Iowa City.
To learn more about the milk crystal from roaches, the scientists used X﹣rays to look at the atoms in it. The data basically revealed the chemical recipe of the roach crystal. They showed that roach milk is a "complete food". It contains sugar with a fatty acid stuck to it. Fatty acids are the building blocks of fats. The protein in the milk is also full of essential amino(氨基的) acids, which are the building blocks of proteins. Since our bodies can't produce the "essential" ones, we need to get them from our food. And so do baby roaches.
Barbara Stay, a biologist at Iowa University, also worked on the new study. She says the new data show that the roach milk is "three times more nutritious than cow's milk and four times more nutritious than buffalo's milk".
Ramaswamy would like to see roach milk turned into a protein supplement to feed hungry people. But not everyone is confident that it can be done.
Marcel Dicke studies insects as a potential source of human food at Wageningen University in the Netherlands. Dicke says this is a "sound study". However, in his opinion, "Extracting(提取) milk from roaches can only likely be done in a destructive way with only small quantities". That means you'd have to raise and kill many bugs to get even tiny quantities of the milk.

I grew up in a middle﹣class family. Dad worked hard to support our family and Mom tried to save money while making sure we had enough food to eat and clothes to wear. One of their greatest desires was to raise decent, loving children who had an opportunity to finish college.
My brother, Gene, never hesitated to learn new things. He had an artistic hand, so he went into fine arts for a while. He also did a lot of screens about computers. He became so good at it that the school hired him to teach there after he completed his studies. My younger brother also pursued computers, following in his footsteps.
Gene did not have a history of any health problems from his very young age to adulthood. One day, he came home from teaching, ate his dinner and went to bed. That evening,my "healthy" brother died suddenly of a cardiac arrest(心跳骤停).My parents were extremely sad.
At the viewing in the funeral house, amidst the sadness, my parents felt so much pride. So many people came and each was relating a story of how they were touched by Gene.
A cleaner came to say that practically every day Gene brought him a sandwich. Finally, Mom found out why Gene had taken so many sandwiches to school! Then there was a man who came in bringing money, saying that Gene had lent him some when he was down and out. Gene had never asked him for the money back.
From the school president to the guard, people came. And because of his good heart and deeds, my younger brother was awarded a full scholarship in the school as a tribute to my dead brother.
In the end, my parents realized that even at the young age of 26, my brother had lived a full life and was very instrumental in helping others live theirs a little better.

During the summer holiday, I thought I should do anything meaningful instead of touring. So I got a job at a fast food restaurant but worked there as a cleaner. I worked 7 hours day for three weeks. The job was boring and seemed endless, in which made me so tired that I nearly stopped it halfway. After all, I stuck to it with determinations. Every day, I started off for work early in the morning, and went home later in the evening. Finally, I finished the job before the new school term begins. Now, I understand how labor means. I think it is a successfully experience, which is worth remember forever.
