Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more food.
In the past ten years,Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus,some farmers lost three quarters of their crops.
Wambugu went to war against the virus. Her search for a way to save the sweet potatoes led to a lab in St. Louis, Missouri.
The lab mainly works on genes, the chemical " computer programs" found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering.
Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced won?derful sweet potatoes.
That's just the beginning, Wambugu believes. Genetically modified foods, she thinks,could help farmers in poor countries grow badly-needed crops，thus，fewer people will go hun?gry-

What is it that makes people laugh? More than two thousand years ago the ancient Greek philosopher(哲学家) Aristotle defined(定义) jokes as the pleasure that results from a feeling of triumph by showing we're better than someone else in a certain way. According to Aristotle and many other philosophers，all jokes depend mainly on showing inferiority in another person or group of persons ― that is, putting it clearly, on showing that they are worse off than ourselves. Jokes raise our good opinion of ourselves at someone else's expense.
Showing how much better than other people we are is only one reason we like jokes. Some?one may also use a joke to express their anger or their cruelty (残酷) or any other kind of action that is not acceptable to us. We feel free to laugh when we hear about someone sliding on a ba?nana skin. The joke lets us express those attitudes which are usually unacceptable to society. This is probably the reason why some of the jokes，especially those involving cruelty，are so popular with certain people.
Besides, all jokes depend on our enjoyment of laughing at something that is strange and out of place because it's different from things which are happening around it. The same situation can be either sad or pleasant, depending entirely on how strange and out of place it is. If a girl in a bathing suit falls into a swimming pool, we don't laugh because nothing unusual has happened. But if a man in a smart suit falls in，the situation is at once unusual in a pleasant way and we laugh. A good joke-teller will always try to build up a situation in which one thing is expected until something unexpected suddenly happens, and so we laugh.
