84、ing because it helps meburn offstress and reduceanxiety.W: Oh yeah, those lies. Ill neverbuy this story. Actually, a study suggests using a fitness tracker can record and encourage you to take 10,000 steps a day. Your immediate action matters. Not your words!M: 10000 steps? That is too much. Will a
85、quarter as much as that help?W: Of course. Clay Marsh from Ohio State University says “Any amount of activity will do. As long as you stick to it, you will benefit.”M: OK. I will start walking tomorrow.Text 10Here is a piece of news for deer lovers. Mary, an 18-year-old senior at Nixon High School,
86、worked out a noise to drive the deer away. A deer jumped into the road and hit her uncles truck. The accident inspired her to look for a deer-defensive measure.According to the data from a science project, deer and humans hear the world differently. People sense sounds in the range of 20 to 20,000 h
87、ertz. Deer live life a little higher. They can hear between about 250 and 30,000 hertz. That means deer can hear sounds well above what people can sense.For her experiments, Mary found a clearing, a small field where she set up a speaker and a remote control. When it sent out a 14,000-hertz sound, i
88、t didnt send the deer fleeing. She increased the sound gradually, and when the speaker broadcast 25,000 hertz, the deer just walked away. The teen expects her warning “whistle” to be broadcast from speakers along the sides of a highway. These will warn the deer to stay away even when there is no car in sight. “Its like a stoplight for animals,” she says. That way it may keep deer off the road.
