3 . Some people think that they will get ill if they use their brains (大脑) too much. It is not true. Through many studies, scientists show us that the more you use your brains, the better it will be, and the cleverer you will become.
Of course, if you want to keep your mind clear and active, you must take a proper rest and study properly. To the teenagers, using their brains in the morning is good for their health.
There are many ways to rest. One is a peaceful rest. Sleep is a peaceful rest. Another is an active rest. For example, take a walk outdoors, do more exercises every day. To change the way of the brains’ activities is also a good way to rest.

6 . Todd Steinkamp left his hotel around 5:30 a. m. for a funeral in Green Bay. Wisconsin. About half an hour into his journey on the road, he noticed a strange sound coming from the front tire (轮胎). By 7 a. m, he still had 70 miles ahead of him, but the noise was so loud that he knew he had no choice but to stop.
Steinkamp thought there was little chance anyone in the little town could help him so early in the morning. Still, he took his chance at a repair shop and asked for help. The worker Geib checked out the car. Geib told Steinkamp the wheel bearing (轴承) was failing. Fixing it would take a few hours. And without being repaired, the car couldn't go further.
Steinkamp started working out another plan. Could he rent a car somewhere? Geib went to the store across the street, but its only rental car wasn't available. Finding another place to rent would need a 40-mile drive. Steinkamp was unhappy and worried at that time. “However, Geib reached into his pocket, pulled out the key to his own truck and gave me,” Steinkamp said. With a smile, Geib said the truck could go 120 miles per hour if needed.
The men had met just 10 minutes before. They didn't know each other's names, but Geib did that. Steinkamp jumped in the truck and drove it to the funeral. When he came back to the shop seven hours later, he chatted with Geib. He thanked the 74-year-old worker, who turned a terrible day into a good one with a great lesson. Just be kind and help if you can.
