February 29th comes up on the calendar only every four years．A year with a February 29th might be good news if you are paid by the day or the week．But it might be bad news if you were born on a February 29th．You have to wait three years in between birthdays!
American English has an expression for the unusual situation． February 29th is called a leap day． And the year with a February 29th in it is called a leap year． This year， 2020， is such a year．
As a verb，the word "leap" means to jump， or to move quickly．"Leap" can also be a noun，meaning a jump， or a sudden move．
In a leap year， the dates jump over one day of the week． Let me explain． In 2017，the last day of the year， December 31st ， fell on a Sunday． In 2018， it fell on a Monday． In 2019， it fell on a Tuesday． But in 2020， December 31st will fall on a Thursday． It jumps right over Wednesday．
The reason for a leap day or a leap year is because our calendar does not follow the earth's orbit（轨道）around the sun exactly． Each year， we have a little time left over． So every four years，we put all that time together into an extra（额外的） day．
Some people choose to marry on February 29th because it is an unusual date．But some ancient peoples would likely tell couples not to do it． Leap years were believed to be difficult， and leap days were unlucky．To be honest， these have no scientific basis（依据）．

How can I become a better person？ This question has been in my head for long． As students， we spend most of our time studying． I know learning at school， of course， makes us better persons， but I always dream of doing more．
Last year，I got to know a group of autistic （ 患自闭症的） children． We called them "the Snails （蜗牛）"．It was hard to communicate with them at first， because they wouldn't like to． After a two﹣week training， I became more skilled． I got closer to them day by day． To my surprise， I found that every one of "the Snails" had his or her own talent． And their colorful pictures on the wall attracted my special attention， though it was difficult to tell what they were trying to express．
Moved by their pictures， I decided to hold a charity （慈善） sale． We walked on the busy street， selling their creative pictures． We sold 60 pictures that day． People thought their pictures were full of imagination．
Back to the question about how to become a better person， I think I am lucky enough to get my own answer．

（3）What is the writer's answer to the question "how to become a better person" ？

Facial recognition technology （人脸识别技术） is widely used today． For example， police use it to search for bad guys． It's also used to unlock phones or doors．
Now， a similar technology，known as facial detection（探测），is entering a new field：the business of advertising（广告）．
Such systems are going through tests in a small number of stores．One facial detection system can judge a person's "happiness" or "fear" level． That helps businesses see how people feel as they look at products or advertisements in the store． Another system can detect whether someone is wearing eyeglasses．If so，sores can send advertisements for new glasses to him．
Facial detection technology is also placed inside some large advertising boards．Cameras in those boards can detect information like people's ages and five levels of feelings﹣from "very happy" to "very unhappy"．
Supporters of the technology say it could improve buyers' experience by showing products they might like or by offering them products at lower prices．
Some are against the idea of using such systems．Pam Dixon，the head of a privacy（隐私）group，is one of them． She thinks__▲__． For example， a business could raise the price of a product according to a person's age and feelings．
However， one store testing the technology explained they wouldn't store people's information like names or ages． And the advertising board system maker said it didn't keep any personal information or record any videos．

In China， each year we produce about 150 million tons of city waste according to report．Where does the waste go？ People usually burn or bury（埋）it．On the other hand， we receive waste from some developed countries． We get useful materials from it．What about the useless part？ Still burned or buried．But is it a proper way？
