If you are lucky enough, you may find the hummingbird (蜂鸟), the smallest bird of the animal world, in a south American forest.
Though the hummingbird is no bigger than a bee and weighs only 2 to 3 grams, it can fly as fast as 50 meters in a second. It can fly forwards (向前) as most birds do, and it can fly backwards as well. The strangest thing about it, however, is that it can stay still in the air, just like a helicopter.
Whenever a hummingbird needs food, it will fly slowly towards a flower. It won’t stand on the flower, as bees do, but just hangs to the flower and then begins to sunk (吸吮) the honey from inside the flower with its needle-like beak.
The hummingbird is very particular in building its nest (巢). It takes great trouble to choose materials. It likes soft ones better than hard ones. Its eggs are so small that a common match box can hold as many as one hundred of them.

Some people dislike hiking because they think it is too difficult. However, sometimes it can really be as easy as going out to the park and walking by the river. The places for hiking should be far away from the cars and the noise. Here’s some useful advice for people to go hiking.
First of all, when you choose your first hike, you should be careful. If you choose a too easy one, you’ll still have a nice day outside to enjoy. However, if you choose a too hard one, you may be very tired and can’t have a good time.
Secondly, it’s good for a beginner to join a group. The people in a group can help each other. If you decide to take a hike by yourself, you should prepare as much as possible. You should wear right shoes to make your feet comfortable. Also, take a map with you. If not , you’ll fail to find your way home.
At last, don’t forget to take a mobile phone or a whistle(口哨). When you are in trouble, you can use it to get help. A pleasant hike will give you a sense of freedom(自由) and you will also have a clear mind(头脑) and then return to your studies after it.
