So far, no one can explain why. 　　Colony collapse is a serious concern because bees play an important role in the production of about one-third of the foods we eat.

3、 As they feed, honeybees spread pollen from flower to flower. Without this process, a plant can’t produce seeds or fruits. 　　Now, a group of scientists and beekeepers have teamed up to try to figure out what’s causing the alarming collapse of so many colonies.

So far scientists haven’t determined the role of genetic diversity in colony collapse, but it’s a promising theory, says Evans. 　　詞匯： 　　honeybee n. 蜜蜂parasite n. 寄生蟲(chóng);寄生生物 　　hive n. 蜂巢; 蜂箱digestive

65、 　　Smart Window 　　Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge1 technology. Researchers are now working on new technolog

66、ies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch2. 　　“It took us a long time to figure out what a window really is,” says Claes Granqvist. He’s a professor of solid-state physics at Uppsala University in Sweden3. “It’s contact with the outside world. You have to have visual contact with the surrounding world to feel well.” So, windows and natural light are important for improving the way people feel when they’re stuck indoors. 　　Yet,
