A
I work in a nursing home and my job is to take care of the elderly.
This year，a very sweet old lady that I cared for，Alice，had gone through a difficult time.She got dementia and so she had been in the hospital twice.In November I was finally able to get her back to her “home”．
Alice had thought her daughter was coming to visit her on Christmas Day and that they were going to have the whole family together like the old days.When she finally realized that that happy moment was not going to happen，she was very sad.Knowing that her daughter was coming after Christmas was not enough to make her feel happy.I hated the idea of her being alone on the holiday!
On Christmas Eve，I gave her a surprise by asking if she would like to go to a candlelight service at church that night.
Instead of taking her to my church，I took her to her old neighborhood church where all her friends were.We got there early and I got her a seat where her friends could see her as they came in.Then soon some of her friends came to the church and they rushed over to greet her and sit with her.
The candlelight service was beautiful and Alice got a lot of love from her old and new friends there.
The truth of the story is that I am the one who got the best gift: the smile on Alice’s face.

Robots performing tasks according to a predetermined set of instructions are nothing new.But robots able to learn how to cook by watching videos are a completely different approach，which is conducted by a group of researchers at the University of Maryland.
If you have posted a video of your favorite recipe on the popular website YouTube，chances are that it will be used by a robot.University of Maryland’s professor Yiannis Aloimonos，leader of the group，said“There exists a large amount of video information on the Internet that our robots can capitalize_on．”robot advances，it reacts to good quality videos.And it will react to even lower quality homemade videos.”
So far，the robot named Julia can make a simple salad by breaking each task into basic parts，such as grasping a spoon，bringing it to the bowl，stirring the salad and observing the results.
But why teach a robot how to understand a video when it can easily follow a fixed program? Aloimonos believes predetermined instructions lack flexibility.He thinks one of the problems is how to make the robot understand and use what it learns during a certain task，the socalled feedback(反馈意见)；another is the introduction of language.(比喻性的) languagen’t need that to create a new world where the robots will be working for us.”
