2．Lichens （地衣） are difficult to see．They don't move．They often mix into the living place．You might not even recognize one if you are looking right at it．
Lichens live on rocks，branches，houses，and even metal street signs．You can find these colorful organisms （微生物） almost everywhere-from deserts to rainforests，and from Antarctica to Africa．They've traveled in outer space，and some scientists think there might even be lichens on Mars．
What you probably don't realize is that a lichen is more than a single thing．It includes two different types of living organisms：a fungus （菌类） and an alga （藻类）．Neither of these organisms is a plant，so the lichen isn't a plant either．
Through photosynthesis （光合作用），the alga gets the sun's energy to make food for the fungus，which is the place for the alga to live in．However，the alga cannot leave the fungus．
Around the world，scientists have found tens of thousands of types of lichens．Many may not even have been discovered yet．As scientists continue to find new kinds of lichens，they are also working to understand how they are connected to one another．By putting together a lichen family tree，they hope to understand why so many different types of lichens have grown in so many places around the world．
Many researchers are trying to understand basic facts about the organisms and their connections．Researchers are also using lichens to examine the health of the environment．

I will tell you about a boy I met．The other Hay after school，I was walking down the sreet while I saw a boy riding a nice unicycle．Which is like a bicycle with only one wheels．Dressing in pink from head to toe，he was singing a song which was sounded like a kid's song．I thought he must be total crazy．Just then，a lady dropped 20-dollar bill on the ground，but he didn't realize it and star-ted to milk away．The boy in pink picked out the money and gave it bark to her．After that，he rode on but soon disappearpd before the lady could thank him．How a strange and good guy!

6．To make up a decision on science or arts learning in the future is a question that upsets a lot of student．Not considered the children's interests or preferences，some parents force their children to make the choice according to their own will，that troubles many students．
In my opinion，we students should talk to our parents or teachers about our decisions，especial life-changing ones．But in fact，when it returned to reality，we're the ones who must live with the choices．So I think parents should try to help their children make best decisions，instead of forcing them to do something that are against their will．
After all，it depends on ourselves whether we'll be science students and arts students．Just let our hearts show them the way．
