四、阅读理解(共15小题,每小题2分,满分30分)
A
Can gems(宝石) be grown in labs?
In Toads(蟾蜍) and Diamonds, a girl's words turn into gems. Scientists can grow gems in labs by melting(融化) mineral ingredients and cooling them. This method is successful and perfect. Lab-grown gems are like natural ones and are used in watches and spaceship windows.
Is super strong glass possible?
Modern science can make strong glass. By heating, cooling, or changing the glass's chemical ingredients, glass becomes as tough as the slippers in Glass Slippers, and scratch-proof(防刮的). You can see this glass in car windows, phones and computers.
Some animals hibernate(冬眠) for months at a time, such as bears, mice, snakes and so on. If scientists understand hibernation, humans might be able to hibernate too, just like Sleeping Beauty, which will be great for astronauts, who need to sleep through the long space trip.
