1、 说明文（用时：7mins） There are many fishing villages along the coast near Kilifi，north of Mombasa in Kenya.The waters are home to parrot fish，octopuse sand other edible species. But despite living on the shores，the children in the villages rarely eat seafood. Their staple meal is ugali，maize(corn) flour mixed with water，and most of their nutrition comes from plants. Almost half the kids here have stunted （发育不足的） growth一twice the national rate. Lora Iannotti, a public-health researcher at Washington University in St. Louis, and her Kenyan colleagues asked people in the villages why the children weren^t eating seafood, even though all the parents fish for a living； studies show that fish and other animal-source foods can improve growth ・ The parents said it made more financial sense for them to sell their catch than to eat it. So , Iannotti and her team are running a controlled experiment. They have given fishers modified traps that have small openings that allow young fish to escape. This should improve spawning and the health of the over-fished ocean and reef areas over time，and eventually increase incomes，Iannotti says. Then, for half the families, community health workers are using home visits， cooking demonstrations and messaging to encourage parents to feed their children more fish， especially plentiful and fast-growing local species. The scientists will track whether children from these families eat better .and are growing taller than ones who don，t receive the messaging. The aim of the experiment，says Iannotti， is to understand which seafood is healthy for the ecosystem as well as in the diet. The proposed diet should also be culturally acceptable and affordable, she says. Iannotti is wrestling with questions that are a major focus of researchers, the United Nations, international funders and many nations looking for diets that are good for both people and the planet. 1.What do fishers choose to provide main nutrition for children in those fishing villages?
