The health risks of smoking are well known， but kids and teens continue to smoke． Many young people pick up the habit every year﹣in fact， 90% of all adult smokers started when they were kids．
You might wonder why people smoke at all． Many people start smoking when they are kids or teens and they try it for many reasons． Maybe all of their friends were doing it or they grew up in a house where all the adults smoked． On the other hand， kids started smoking in order to look cool， act older， lose weight， or feel independent．
But no matter why they started， many smokers （ men， women， boys or girls） wish they could stop． Stopping smoking is hard， though， because there is nicotine （尼古丁） in cigarettes （烟）． Someone can get addicted to（沉溺于） nicotine within days of first using it． When something is addictive， your body and mind will tell you that you need it to feel OK． If you don't get it， you might feel sick， stressed out， or get angry．
Stopping smoking mostly has two steps． The first step is to deal with your dependence on nicotine and the other is to break the habit of smoking． When you stop smoking， you may have to wait a few days or even weeks before the nicotine finally leaves your body．
Most importantly， we must make sure kids and teens understand the dangers of smoking as early as possible．

Do you like animals？ Do you want to work with them？ If your answer is "yes"， you might be interested in the job of a vet．
A vet is an animal doctor． There are over 60， 000 vets in the US． Some take care of pets like dogs， cats and birds． Some care for farm animals like horses and cows． Some work in zoos and they work with elephants， tigers， lions， pandas and so on．
It's difficult to become a vet in the US． Besides the love for animals， one has to study really hard． He must first finish college， and then go to the veterinary（兽医的）school for four years' study． Working as a vet is not easy， either． They often work long hours， but many vets say that their job is exciting and fun．
Jane is a vet working in New York． "I work 10 hours a day． It's long？ I just feel the time flies so fast when I'm working． I always think I have the best job ever， "she say．

We all need cash（现金）in order to live our lives． However， something called digital currency is slowly taking the place of cash． A currency is a kind of money． Usually， we use currency when we talk about a country's money． If something is digital， it only exists（存在）on a computer， So "digital currency" means money that only exists on computers．
Lots of people have digital currency accounts（账户）． They use a credit card（信用卡）to change their real money into digital money， and then the money goes into the digital currency account． A lot of people wonder，"Why in the world should I change my real money into digital currency？" This is a fair question， but there's a good amswer． If you want to buy something online， then you usually have to use digital currency．For example， if you're in China and you want to buy something in Canada， then you' ll have to pay with digital currency．
Many people still don't trust digital currency． Some people think that if they can't hold their money in their hand， then it doesn't seem real． These people don't feel comfortable when they see numbers on a computer screen． The computer tells them that their money is safe but these people don't really feel safe． Another problem is security（安全）． There are hackers all over the world．A hacker is a person who steals computer information． If a hacker gets the password of your digital currency account， he or she can steal your money．
You have to decide whether or not you trust this new invention． Just remember one thing： If you want to buy something online， then you probably won't have a choice．You'll have to use digital currency．

In a rainforest there are tall trees． The top of these trees is called the canopy． Scientists want to learn about the canopy． They want to learn about everything that lives there， but it has not been easy to get to the canopy．
