Have you ever seen fireflies? Fireflies are small insects. You can't see t 1 in any seasons except summer. The lights made by fireflies are probably one of the most magical things to see on a summer night. Do you w 2 how fireflies make the light?
There is a part that can make light under a firefly's stomach. Fireflies take in air and use it to p 3 light with special cells(细胞). Different kinds of fireflies have their o 4 special flash patterns, just like humans have different languages. They use these flash patterns to find other members of their group.
Fireflies m 5 use the light to get friends' attention(注意). The males fly around while turning their lights on and off, h 6 to get the attention of a female. They try to flash very quickly because the faster the males flash, the more attention they can get from females. Fireflies also use the light to make their enemies(敌人) a 7.
If you haven't seen many fireflies lately, you are not alone. The n 8 of fireflies may be dropping because of some reasons, such as light pollution and the use of chemical medicine. Another important reason is that fireflies' l 9 places are destroyed(破坏) by humans. L 10, Chinese scientists recently have found three new kinds of fireflies in Yunnan. Yunnan might have the right environment for these magical insects to live in.
