When my family moved to America in 2010from a small village in Guangdong，China，we brought not only our luggage，but also our village rules，customs and culture．One of the rules is that young people should always respect（尊敬） elders．Unluckily，this rule led to my very first embarrassment in the United States．

3．What's going to happen in the future？Here are some things that scientists say are most likely to happen 10to 30years from now．
1．Digital money
We used to pay with cash （现金） for everything we bought．In fact，we are already using one type of digital money，when we swipe （刷） our bus pass or use a credit card （信用卡） to shop online．
You have to admit that using a card is much easier than searching your pocket for change．It is also safer than carrying a lot of cash on your person．People in Sweden completely stopped using cash last year and the US might be next．
2．Bionic （仿生的） eye
People who are blind may have a chance to get their sight back-by wearing bionic eyes．A blind eye can no longer sense light，but a bionic eye can use a camera to"see"the environment and send data（数据、资料） into the brain．
Although the bionic eye that's out now only allow patients to see lights and unclear shapes，a high resolution（高清的） version could be just a few years away．
3．Self-driving car
Unlike a human driver，a self-driving car won't be distracted （分神） by a phone call，the radio or something outside the window．Sensors （探测器）and cameras on the car would allow it to keep strictly to the rules of the road and keep a safe distance from other cars．This would greatly reduce the number of road accidents．Many vehicle companies are now planning self-driving cars．By 2040，driverless vehicles will be the main vehicles on the road．
