根据《消防法》规定，建筑构件、建筑材料和室内装修、装饰材料的防火性能必须符合（）。

Last Saturday night Jenny was walking through a mall in London , texting on her phone. She wasn’t watching where she was going , so she fell into a sewer (下水道) and got trapped. Luckily she didn’t hurt badly. She quickly climbed out and walked away. But her accident was caught on a mall camera. Then someone posted it on YouTube. The video was viewed almost 2 million times and received national attention. Jenny was angry with this, but she learned a deep lesson: Texting while walking is dangerous. This time I just fell into a sewer. Next time I didn’t know what would happen. Maybe I would be knocked down by a car or something else. It was horrible.

Jenny may be famous for her mistake. After that, she was laughed at by her friends and workmates. She regretted what she had done. But it was too late. However, she wasn’t the only one who got into trouble while texting on the phone. In 2008, more than 1000 Englishmen visited hospital for similar reasons. They were walking and texting or talking on the phone. Suddenly a wall appeared! Or a hole or something like that got in the way. There were cuts, bumps, broken bones and even worse result happened on them.

So we must be careful when we are walking. Don’t send messages or talk with somebody on the phone while walking. Or you may hurt yourself and become another Jenny in the future.
