    The cicada（蝉）has an interesting life cycle, but most of us only become aware of these insects in summer when they reach adulthood and begin their calls. 1.Some, like the Golden Emperor, have complicated songs. The summertime calls of the cicada are made by adult males to attract females. Their eggs are usually laid in scratches cut through the skin of the tree. Once it has been completed, the adults die.

When the eggs hatch, the larvae（幼虫）drop to the ground and live under the soil.2.They spend as little as several months for some species or as long as several years for other species buried under ground, shedding（蜕下）their skin as they grow. They shed their skin for the last time to become adult cicadas with their wings. 3. A few days after coming out of the soil, the males call for mates and cycle begins again.

The Golden Emperor, whose call is quite different from others, is one of Australia's biggest and prettiest cicadas. 4. The Golden Emperor calls in groups, but getting to see one up close is very difficult as they fly away when approached. Also, as their breeding season progresses, they gradually move higher up the tree trunks.5. The Golden Emperor is a delight just to listen to if you can't see the insect itself.

A.Not all cicadas have simple, loud noise.

B.This act makes their calls the only sign that they are still around.

C.The larvae attach themselves to tree roots and feed on their liquid.

D.When they have become mature, they come out of the soil as a group.

E.Their songs call on female to fly to them and fight for next generation.

F.If that happens, they will fly away and go to some place that they really love.

G.Their call starts with two notes and then rises sharply before it suddenly drops down.
