Space is a lonely place. Hundreds of thousands of kilometers from home, astronauts have a hard life. It stands to reason that, once in a while, they need to have a good cry. But this is a lot harder than it sounds.
We still know very little about space, and about living in zero gravity (重力). In fact, we are discovering new things every time astronauts take to the sky. As The Atlantic reported in January, crying is not all that simple in space. This is because when a person normally cries, gravity makes their tears move downwards. But in a spacecraft, this is not the case. Here, there is no gravity, which is why we so often see pictures of astronauts floating around. This means that, strangely, when you cry, your tears have nowhere to go. As a result, they just stick to your eyes.
In May 2011, astronaut Andrew Feustel experienced this. “Tears,” as he said, “don’t fall off of your eye...they just kind of stay there.” This can be quite painful. In space, your eyes get very dry, and the added moisture is annoying. Sometimes, things get even unusual. The astronaut Ron Parise told The Atlantic that when tears get big enough, they “break free of the eye and float around”.
No one can be quite sure why we cry. Why should water in our eyes have anything to do with feeling sad? If you stop to think about it, crying is a very strange thing indeed. And now, thanks to the wonders of space, it just got even stranger.What’s the main idea of the first paragraph?

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．

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．
One way to reach the top is by a light raft filled with air． It has a huge net （网） on it．A hot air balloon drops the raft onto the trees．Scientists can stand on the raft and look into the trees．
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．
Meg's job is to keep finding out more． She wants to help find the secrets of treetops．There are still millions of animals that no one has seen． Many of them are in the treetops．
