A British dog-lover has invented a high-tech way of feeding his pet by Twitter( ,). Computer expert Nat Morris ,30, has designed a system to give his pet a "tweet treat" by sending him a Twitter message. His dog Toby gets some delicious dog biscuits from a computer-controlled food machine whenever Nat sends a message to "@ feedtoby". Nat often works away from home and isn't always able to feed Toby by hand. But his new invention allows Nat to feed his dog from anywhere in the world. Nat said, "Toby ly loves it. At first he didn't know what was going on. Now he sits underneath the machine, wagging his tail and waiting for the food to drop." Nat fills the food machine with small pieces of dog biscuits, but not too many in case four-year-old Toby gets too many messages. And Nat has even equipped his house with an online camera so he can see Toby enjoying the food at his home. But one problem is that friends and family have been so amazed with the "tweet treat" machine that they have started sending tweets to Toby too. So Nat has had to restrict feeding time to make sure Toby doesn't turn into Tubby. "People have been sending him tweets at all hours of the day, so I had to limit it to between 9a.m. and 9 p.m. . I'm thinking of doing an updated one which can measure his weight before he is fed, just to make sure he's not putting on too much puppy fat," explained Nat. How Nat's Twitter Feeder works: When a message is sent to @ feedtoby, it is received by a mini -computer that is linked to the feed machine. When the mini-computer receives the message, a bell rings and Toby comes running over and sits in front of the feeding machine. Next, the machine's motor pulls open a trap door which releases a serving of food. The doggy biscuits then drop into Toby's food bowl. Finally a digital camera takes a photo of him and sends it back to Nat on Twitter -- so he knows Toby has been fed. It can be learned from the passage that Toby _ . A) sits beneath his feeder all day long. B) is now used to being fed by machine C) doesn't know what happens to the feeder D) no longer receives tweets from Nat's friends

For the 17 years my life was very happy. Then the first sad thing happened. My mother became very ill, and soon she knew that she was dying. Just before she died, she asked Elizabeth and me to go to her room. She held our hands and said, "Victor and Elizabeth, my children, I'm very happy because you love each other, and because one day you'll get married. Everyone in the family loves you, Elizabeth. Will you take my place in the family, my dear? I can die happy if you look after them when I have gone." My mother died and we were very sad, because we loved her dearly. Elizabeth was brave and helped us; her sweet smile gave us some happiness in the unhappy days after my mother's death. The time came for me to go to university. I didn't want to leave my sad family, but we all knew that I should go. It was hard to leave, too, because the parents of my good friend Henry would not let him go to university with me. So I had gone alone. On my first day at university I met my teacher, Professor Waldman, who was one of the greatest scientists in the world. He gave a wonderful talk to all the students who were starting at the university. He ended his talk by saying, "Some of you will become the greatest scientists of tomorrow. You must study hard and discover everything that you can. This is why God made you intelligent--to help other people." After the professor's talk, I thought very carefully. I remembered the storm when I was 15; I remembered how the lightning had destroyed the tree. From then on, I wanted to use electricity to help people, and I wanted to discover the secrets of life. I decided to work on these two things. I started to work the next day. I worked very hard and soon Professor Waldman and I realized that I could learn to be a very good scientist. The professor helped me very much, and other important scientists who were his friends helped me, too. I was interested in my work and I did not take one day's holiday during the next two years, I did not go home, and my letters to my family were very... Which of the following is TRUE according to the passage? A) Elizabeth married shortly after Victor's mother died. B) Elizabeth was a brave girl who loved Victor and gave him much help. C) Victor's mother was very angry when she knew he loved Elizabeth. D) Victor did not want to leave his family because his mother died not long before.

About ten days ago, I started to write an article on a parenting subject. I wish I could publish it. But in the days between the writing and the publishing, an unfortunate thing happened. My article discussing the lost art of walking to school was finished three days before an 8-year-old boy named Leiby Kletzky in Brooklyn tried to walk home for the first time from his summer camp. Today I will not describe the details around the Leiby Kletzky killing, except to point out the obvious fact that it terrified every parent who heard about it. What happened this week is one of the biggest reasons why so few kids walk to school now. In theory, walking to school is a wonderful habit, which can teach children independence, introduce them to their neighborhoods and encourage physical activity. It's better for the environment, eases traffic and is just generally the most fun choice. However, many of us parents don't allow the habit, mentioning the problems of logistics and distance. What we talk about less often is our fear. Maybe that's the heart of the matter. Indeed, it is an understandable reaction. But it is not a necessary one. What happened this week is extremely rare. Separating out the fact from the feelings is a difficult thing to do. Very few of us were ready to breathe easy about sending our young children off by themselves no matter what happened. We are far more worried now. The good news is that we don't have to be. Those children who go to school by themselves can be escorted when the neighborhood forms a "walking school bus". That's when designated parents walk with groups of children from home to school. With the benefit of safety, it allows kids to enjoy one of the joys of childhood. It's an easy, affordable choice. A walking school bus is a good idea that parents thought of. Proper measures are usually out there. Sometimes all they take is a little cooperation and some courage. What is the author's attitude towards walking school bus? A) Doubtful. B) Supportive. C) Worried. D) Changing.
