近来，有多起儿童被遗忘在车内，中暑身亡的事件发生。华盛顿邮报报道，美国新墨西哥州的一名青少年的新发明或许可以避免类似的悲剧再次发生。

车内中暑报警器

The Washington Post: The unthinkable keeps happening. The 18th hot car death of the year was recorded last week — on the same day that a national public service campaign kicked off to warn parents about the dangers of leaving kids in hot cars.

One New Mexico teenager's invention might someday prevent such deaths.

Alissa Chavez, a 17-year-old from Albuquerque, said she has designed a car-seat alarm system called "Hot Seat" that might prevent people from accidentally leaving young children in cars. She's now trying to raise money to build a prototype.
