The Internet nowadays opens a wide world to people，including teenagers，but many parents worry that their children may meet with something unhealthy when searching online．In order to solve this problem，a new search engine for children called Kiddle has appeared．
Search results are filtered（过滤），so only safe website are shown and descriptions are written in simple language．Searches with bad words are shut off，too．
Kiddles uses the same colors as Google in its logo and a similar design on its homepage，too--with an extra robot picture．
The top three Kiddle search results show safe websites and pages written specially for kids，and those websites and pages are well chosen and checked by Kiddle developers．
The fourth to seventh results will be safe and trusted websites that are not written for adults．They provide expert content，but are harder for kids to understand．
Unlike on Google，most results appear along with large thumbnail pictures（缩略图）to make it easier for children to find what they are looking for．For example，when searching for"meow meow"．Google produces pages for information about a drug（毒品）that has"meow meow"as its nickname（绰号），but Kiddle lists information only about cats，even with some cartoon pictures．
The company explained，"Websites which appear in Kiddle search results satisfy family-friendly requirements，as we filter websites with unhealthy content．"
