Shopping centers，stadiums and universities may soon have a new tool to help fight crime.
A California company called Knightscope says its robots can predict and prevent crime. Knightscope says the goal is to reduce crime by half in areas the robots guard.
William Santana Li is the chief executive officer of Knightscope. He says，"These robot security guards will change the world. Our planet has more than seven billion people on it. It's going to quickly get to nine billion people. The security equipment that we have globally is just not going to develop that fast. The company's Autonomous Data Machines can become the eyes and ears of law enforcement（执法）."
"You want them to be machines plus humans. Let. the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work，so it's always working all together."
The machines do not carry weapons but they have day and night video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.
Some people may become concerned about their privacy, especially in connection with the video recordings. Some people may worry that such recordings will appear on the Internet. Eugene Volokh, a law professor at the UCLA School of Law, says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.
William Santana Li says there is a long waiting list for the robots in the US. Workers in the company are working overtime to meet the demands of the market. At least 25 other countries are also interested in these robot security guards.

Throughout life, we come across many people who impact us in a way. The person who left a great impact on me is my dad.
Three months after turning fourteen, my life was great. I was getting settled into a high school; my grades were already starting off greatly and I was making friends. One day as I came home from school, I walked into our living room, finding my mom and dad talking. My parents turned to me and told me to sit down because there was something important they had to tell me. I soon found out that my dad’s liver (肝脏) was failing and he needed an immediate transplant. I was shocked and confused. He was working and never looked sick. My parents told me not to worry because everything would be fine. Four months had passed and my dad still had not received a new liver; he was progressively getting worse. His body seemed to be getting weaker, but he constantly said he was fine.
It was getting hard for my family and me. My dad had to quit his job leaving my mom to be the only provider. I had to take on the responsibility of cleaning the house, cooking meals and checking on my dad while my mom was at work. I had to cut back on hanging with my friends because my dad was beginning to go in and out of the hospital. My focus for school was starting to slip. So were my grades. Two nights before my school spring break, my mom received a call from the hospital that my dad had been in a car accident and that he was in hospital. Surprisingly, my dad hadn’t received a scratch on him. Then next night my mom received a call from the doctor stating that there was a liver that matched my dad’s body and that he needed to get to the hospital immediately.
Para. 1
My mom and I rushed to the hospital and my dad was brought into surgery.

Pare. 2
Having to take on so many responsibility at home and constantly worn about my dad has helped shaped me into the person I am today.
