Garage sales (旧货市场) are a strange pastime. I am not interested in other people’s items. My mother was, and she convinced me to her. We went to several garage sales and finally stopped at a cottage. The owner told me that he and his wife were moving away. His wife had been a (n) before she retired.

As we were the sale items, I heard the gentleman’s wife say her name to someone, and I realized who she was. She looked at me and said, “ You are Lisa Miller.” I at her in awe(惊叹)for it had been thirty years I had been in her class.

My mother to her for any trouble I might have caused. She that if this woman remembered me after so many years, I must have done something . My teacher looked at my mother and said, “Oh, no, she was very good,” and my mother watched her in .

My teacher explained during the last week of school, I brought her a . She told us she planted the Lamb’s Ear in her garden.

There at her home, among all her , was a piece of my life that she had nurtured(培养).

In that moment, she taught me more about life than I could . We give pieces of ourselves every day without thought or expectation. We seldom envision(展望) the that we have on others’ lives.

Mosquitoes(蚊子) ruin countless American picnics every year, but around the world, this bloodsucking beast isn’t just annoying— it causes a health problem. More than a million people die from the spread of mosquito-borne diseases like malaria and yellow fever each year. Attempts to control populations via insecticides like DDT have had ruinous side effects for nature and human health. Neurobiologist Leslie B. Vosshall has a different solution for stopping the insects and the spread of disease. “I believe the key to controlling mosquito behavior is to understand better how they sense us,” she says.

At their Rockefeller University lab, Vosshall and her colleagues are studying the chemical sensory processes by which mosquitoes choose hosts. How do they sense heat, humidity, carbon dioxide, and body odor(气味)? What makes some people more attractive to a mosquito than others? It takes blood and sweat to find out. To study how mosquitoes assess body odor, Vosshall and her teammates might wear stockings on their arms and keep from showering for 24 hours to create sample smells, Then comes the hard part. They insert their arms into the insects’ hidden home to study how mosquitoes land, bite, and feed and then they document how this changes. This can mean getting anywhere from one bite to 400, depending on the experiment. Studying male mosquitoes is more pleasant. Since they don’t feed on blood, the lab tests their sense of smell using honey.

Vosshall and her team have also begun to study how genetics contribute to mosquitoes’ choice of a host. She’s even created a breed that is unable to sense carbon dioxide, an important trigger for the insects. “By using genetics to make mutant(变异的) mosquitoes, we can document exactly how and why mosquitoes hunt humans,” Vosshall says.

Once Vosshall figures out what makes mosquitoes flock to us, she can get to work on making them leave us alone. Many of her lab’s proposed solutions sound simple enough, including bracelets(手镯) that carry long-lasting repellants(驱虫剂) or traps that can reduce populations, but the breakthroughs, when they come, may save millions of lives in the developing world—and a lot of itching everywhere else.
