When was the last time you saw three men running down a forest trail（小径）in the rain wearing flip-flops（拖鞋）？That's what my friend Brandon, Josh and I were doing last autumn. We were looking for a waterfall（瀑布）.We didn't have much time to get to the waterfall and back, so we were running. We were wearing flip-flops to prevent our shoes getting dirty.

    It was raining, but lightly. It kept us cool as we climbed over giant stones and through a shallow（浅的）stream. We followed red arrows（箭头）and crossed that stream several times, walking on toward the promised waterfall. Time was not on our side, however, and we were forced to turn around. As we started back, we looked at the shallow stream we had just crossed. Where did this rushing river come from? That was when we realized a flash flood was around!

    In the few minutes the water rose at a fast speed. Now there were no big stones to be seen-only what looked like lumps（隆起）covered with rushing water. We had no choice but to move our way back carefully in the rushing water -in flip-flops. We had crossed the stream not once or twice, but six times in search of a waterfall that we never even reached!

    With most of the crossings, we needed each other's help if we didn't want to be washed away by water. Wet all over, we felt relaxed after we made the last crossing.

    "My dad always told me to keep off a river when travelling in the rain." Josh said as we hurried back down the path.

    "Why didn't you tell us that earlier?" I laughed.

    "Would it have made a difference?" came the reply.

    He had a point.

    Every living thing on Earth is either a plant or an animal, right? Wrong! Many organisms（有机体）in our world are neither. Some of them float through the air, and some lie hidden in the ground. They do not need sunlight to survive, and if the weather becomes too cold, they can become inactive until conditions improve.

    What are these? They are called fungi(菌类), and you see them almost every day. Many kinds of fungi seem disgusting, such as the green black things that appear on the food which are left too long in the refrigerator. But other kinds are not so bad. For example, the yeast that is used to make bread and mushrooms (蘑菇) are both fungi.

    What makes fungi different from plants and animals? An animal can move around by itself. Fungi get around too, but they don't have feet, wings, or tails. They have to wait for wind or some other outside force to move them. Plants are different from fungi because they have chlorophyll（叶绿素）. It helps them make food from the energy in sunlight. Fungi do not have chlorophyll.

    Some fungi are bad, while others are not. Some fungi cause diseases, such as athlete's foot, which makes feet uncomfortable. Other kinds of fungi can be used to make medicines, which have saved many lives.

    Fungi clean up more than wounds, though. They are the world's first recyclers. Without fungi, our world would be a mess. Since fungi cannot make their own food as plants do, they must get their food elsewhere. Many fungi get their food from dead plants. They break them down and turn them into soil. The fungi get a meal, and the world gets a housecleaning.

    How to Create a Mind Map

    Most of us think visually but we write textually. {#blank#}1{#/blank#} It also makes the information we list more difficult to process, remember, and share.

    So, how do you create a mind map? The most basic method is to just use a pen and paper, or a marker and whiteboard. It begins with a central topic or idea, then flows outward.{#blank#}4{#/blank#} The next level of topics is represented by branches extending from it.

    There aren't really any rules for creating mind maps.

    Mind maps are extremely effective for taking notes, planning a project, brainstorming an idea, presenting information to others, and many other uses. Take out your pen and have a try.

A. They help to clarify thinking.

B. This goes against how our minds actually work.

C. They help us save time by focusing on key issues.

D. A mind map is the perfect answer to this dilemma.

E. Think of it as a tree, where the central point is the trunk.

G. Others like to add colors, pictures, or symbols in their mind maps.
