World Pangolin(穿山甲) Day is on the third Saturday of February each year. This year, it fell{#blank#}1{#/blank#}Feb.18. It's a day{#blank#}2{#/blank#} (help) people know more about pangolins.

    Pangolins are animals that live in Africa and Asia. They have scales(鳞片) on their skin and eat ants.  Pangolins are important {#blank#}3{#/blank#} (animal) because they help to protect trees in forests.{#blank#}4{#/blank#}, pangolins are now endangered. According to the International Union for Conservation of Nature (IUCN), more than 1 million pangolins have been killed or sold in the last 10 years. Last year, IUCN added the pangolin {#blank#}5{#/blank#} the world's "endangered animals list". Now pangolins are more endangered than pandas.

    The growing trade of their scales and meat is the main reason for their decline (下降) in number. Many people in Asia and Africa eat {#blank#}6{#/blank#}(they) meat, and some even use their scales to treat sick people.

    Luckily, this situation {#blank#}7{#/blank#} (get) better. The government now stops anyone from {#blank#}8{#/blank#} (buy) and eating pangolins in China. Breaking this law will be regarded {#blank#}9{#/blank#}a crime. The trade of pangolins across the world is also not allowed.

    "I hope more people will join us to protect pangolins from such a {#blank#}10{#/blank#}(sadly) situation," Zhou Canying told Xinhua News Agency. Zhou is head of the Wildlife Protection Association of Changsha, Hunan Province.

    People have always been interested in animal communication and scientists have done a lot of research {#blank#}1{#/blank#} this subject. Most animals communicate by smell. Dogs are famous for this. When a dog walks outside, it learns about other dogs by {#blank#}2{#/blank#} (smell) things. Dogs {#blank#}3{#/blank#} (help) the police since a long time ago. Everyone has heard birds singing. Research has shown that many other animals use sounds {#blank#}4{#/blank#} (communicate). Frogs and insects communicate with sounds. Usually the "men" make sounds to invite the "{#blank#}5{#/blank#} (woman)". Whales and elephants {#blank#}6{#/blank#} use sounds to communicate. These sounds can travel very far through water or the ground. However, it is {#blank#}7{#/blank#} (possible) for humans to hear some of the sounds. They are {#blank#}8{#/blank#} too low or too high for us. Animals have always used body language to communicate as well. {#blank#}9{#/blank#} a dog puts its tail under its body, it is scared. When a dog wags its tail and {#blank#}10{#/blank#} (open) its mouth, it is happy.
