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．
Meg is an American biologist， ecologist（生态学家）， explorer， writer， educator，and public speaker． Since she knows a lot about trees， she is sometimes called Canopy Meg．Meg has always liked trees． When she was a child，she made tree houses．Now， she has climbed to the top of trees all over the world and done great research， so she has got a
nickname called "Einstein of the treetops"．
Walkways in the rainforest were Meg's idea．Now， they are used by many people． A walkway is like a bridge that goes between the trees． It is safe and it doesn't harm the trees． A walkway， however， cannot help scientists reach the top．

A tower crane is also a good way to get to the top． It can go above the tree tops． It can go all the way down to the ground， too． Scientists are learning about life in the canopy． They have learned there are millions of insects（昆虫） that are eating leaves in these treetops．

If you wear glasses， there's good news for you．（1） A new study has found that needing to wear glasses is connected with higher levels of intelligence．
In the study， researchers from the University of Edinburgh studied data（数据）on brainpower and genes． Genes， made up of DNA， are information in the cells of our body． They determine how we look and how our bodies work． （2） They found a connection between brainpower and physical characteristics including eyesight and health． People who were more intelligent were more likely to have genes that might show they need to wear glasses． The researchers also found that being smarter has some advantages． They found ways in which smarter people have fewer health problems．
（3） They are not proved（证实的）causes． It is easy to prove that two things are connected． It is harder to prove that one thing， like intelligence， causes the other， like needing glasses．
Forget genes though． Wearing glasses makes people think you are more intelligent， even if you don't need them． A number of studies have found that people who wear glasses are usually seen as smarter， more hard﹣working and honest． （4） They get the people they work for on trial（审 判）to wear glasses． Glasses are also used to show someone is intelligent in movies and on TV．
（5） People who do not need glasses sometimes wear them． They wear them just to look smart or cool． Glasses are not only for needs． Wearing glasses can also be cool． Many movie stars are fans of fashion glasses．

A．Many lawyers use this to help them． B．We must try our best to protect our eyes． C．However，these are all simply connections． D．You might be smarter than those who don't． E．Ideas about wearing glasses have begun to change． F．Wearing glasses sometimes makes people look silly． G．The researchers studied the genes of over 300，000 people． |
