Owners will also enjoy the playground, tennis courts and basketball courts. Dolores Dog ParkThe grounds of Dolores Park once served as camps for those who were left homeless by the 1906 earthquake, but now often visited by crowds of Mission District people. Four-legged friends can also wander about carefree off-leash while making friends with other members of the doggie community. Pine Lake Dog ParkNoteworthy for its place as a rest stop for hundreds of species of birds to fly to and from warmer climates, Pine Lake Park is also prized by city dogs and their owners for their nice hiking paths, picturesque lake suited for swimming, and an off-leash area on the parks west end that lets dogs run free. Buena Vista Dog ParkAt 146 years young, Buena Vista Park is San Franciscos oldest park. Dogs and owners with plus energy will love burning it on this parks steep paths and winding staircases.

Inspired by the current litigation （诉讼）in Flint, Michigan, a case of water pollution from 2014 to 2015, Rao designed a new testing system that resulted in her being named Americas Top Young Scientist for 2017.Rao had been following the water problem for about two years. She was amazed by the number of people affected by lead pollution in water and wanted to do something to change this. Gitanjali spent months trying to convince local high schools and colleges to give her lab time to continue her experiment. At home, Gitanjali worked on her project in the “science room” she asked her parents to create for her. Rao has created a device that uses three parts: a cartridge, a Bluetooth reader and an app. To put it simply, the cartridge contains carbon nanotubes（纳米管） that react to lead. This reaction is then registered by the Bluetooth reader, which sends a signal to a mobile app that can tell you immediately if your water is safe to drink.Rao appropriately named the device Tethys after the Greek goddess of fresh water, and is hoping to make a little improvement to get the device on the market. While we may not be aware of any lead pollution present in our aging pipelines, lead poisoning can cause delays in physical and mental development. With Rao believing that the “purpose of science is to make a difference”, her incredible invention could make a difference to millions of people in the United States. 24.

The water pollution litigation in Flint.26. What do the carbon nanotubes function as?A. Sending immediate signals.B. Recording the reaction results.C. Detecting the presence of lead.D. Showing the water quality results.27. What does the author think of Raos invention?A. It will lead Rao to make a fortune.B. It will help millions of Americans drink safe water.C. It will promote the development of science in America.D. It will soo
