Task 1. Reading
Read the text and mark the statements T (true) or F (false).
Wolong National Nature Reserve
            The Wolong National Nature Reserve in south-central China is the place to go if you want to see amazing people working hard for a great cause: helping giant pandas. The reserve has three main facilities for you to visit.
            Start your tour at the Bifengxia Giant Panda Base. The location itself makes it worth the trip as it is in a valley and has several waterfalls. Go inside the facility and you'll soon see that this is where the baby bears are raised. It's like a panda nursery. It's best to go between July and September if you want to see ones that have just been born. After this, you should visit the Dujiangyan Panda Base, which is designed for panda play time. You get to be “mum” or “dad” panda for a day. You'll help get the little ones out of “bed”. And when it's time for them to eat, you can even help make their food.
             When play time is over, head to the Gengda Giant Panda Centre. This is the brains of the reserve. That is, this is where the staff does research and educates the public. You will learn about how this centre gets giant pandas ready to live on their own in the wild. Think of it as a panda school and graduation. So what are you waiting for? Plan your panda trip today!
