This month, we went on a five day trip to Xishuangbanna, a beautiful place in the south of Yunnan Province. The weather there is hot and wet. There a {#blank#}1{#/blank#} many kinds of plants and animals. I want to i {#blank#}2{#/blank#} some interesting things we saw to you during our trip.

In the jungle(丛林), we saw a twining(缠绕的)plant. These P {#blank#}3{#/blank#} grow when seeds-seeds mainly from banyan tees (榕树)are moved by animals or wind to some other trees. These seeds gradually grow, developing their own aerial (空气的) roots. Little by lite, they will get themselves around the host tree and f {#blank#}4{#/blank#} kill it, just like a snake kills its enemy.

A {#blank#}5{#/blank#} thing we learned is that when a tree gets big and strong, some of its aerial roots will grow into the ground and develop into a new tee, just like the way cell division (细胞分裂) works. The w {#blank#}6{#/blank#} tree will look like a small forest. I think this is quite a {#blank#}7{#/blank#}.

In the forest, you will sometimes find some red leaves among the green leaves. Why is that?

One reason is that the sunshine is very strong in Yunnan. The trees n {#blank#}8{#/blank#} use all of their leaves in order to do photosynthesis (光合作用) and grow, so the color of some of the leaves c {#blank#}9{#/blank#}to red.

We really enjoyed our trip to Yunnan. We learned a lot about n {#blank#}10{#/blank#} and had a rally fun time. I hope we can take more trips like this in the future.
