Farmers can produce more by planting several different crops in the same field.But their success depends on which crops they plant together and how they mix (混合) them in the filed.In the past, the only way the farmers could learn which crops grow best together is to plant them and wait for the results.Now, however, a computer can give them answers.A new computer program written by Dr John Vanderwell of Michigan University can tell a farmer which plants grow well together and which do not.It can tell him how to plant the different crops; if he should plant each in a separate row, or mix the crops in the same row.It can tell the farmer how changes in planting each of the crops will affect the production of all of them.And it can tell him which plants can help reduce losses (损失) from diseases.

“Lizzie, there’s a letter for you!” Emily called up the stairs to her sister. Elizabeth looked down. “Is it from Harvard? They refused my application once.” Emily answered, “No, it’s from Yale.” Quickly, Elizabeth walked downstairs. She took the letter and opened it. “Rejected again,” Elizabeth said unhappily. “Who says women can’t be doctors?”
“They are fools not to accept you. You can’t let them stop you, Lizzie,” Emily said.
“I won’t. I’ll apply to (申请) Geneva Medical College,” Elizabeth told her sister. As it turned out, the professors at Geneva Medical College were not fools. They allowed Elizabeth Blackwell to study medicine.
In 1848, a year before Elizabeth would graduate, a typhoid epidemic (伤寒流行病) broke out in New York. Elizabeth wrote to Emily. “There’s an outbreak (爆发) of typhoid, and I am going to help. It is dangerous, so if I should not survive, please do me the honor of studying medicine yourself.”
Emily replied, “Encouraged by your dream and success, I have decided to study in medical school, as well.”
Having survived the disease, Elizabeth tried to set up a private medical practice. “I graduated first in my class but no one believes a woman can be a good doctor,” she said to Emily one day. “All I hear is that doctors should be men, while women should stay home to cook and clean.”
Emily said worriedly, “I will graduate in June with my medical degree. What shall we do?” Elizabeth thought for a while and replied, “There’s a big house in the poor part of our town. We can practice medicine there for people who couldn’t afford care.”
Soon with the help of some friends, Elizabeth and Emily bought the house and opened a hospital for poor women and children. “We’ll have an all-women staff (员工),” Elizabeth said. “And later, we’ll add a medical college for women!” Emily added. At last, Elizabeth realized her dream of being a doctor.
