Read the following article and answer the question. Article: 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.

Question: Read the following article and answer the question. Article: What is funny? The short answer is: Who knows? The joke that causes a burst of laughter from one listener might be met with a puzzled look from another. In general, you should avoid jokes at any business or social gathering where there are more than two people in your conversational group. If there are only two people -- and they consist of you and your best friend -- go ahead and tell it. Admittedly, a few people possess a perfect sense of timing, appropriateness, and joke delivery. You are probably not one of them. You might be quite funny and have many great jokes. But there's a place for jokes -- over dinner with family, hiking with friends, but business or social affairs with colleagues and acquaintances are not it. It takes a whole other level of joke-telling ability to put a joke into the more formal conversations. The best jokes come into the conversation so that by the time listeners realize a joke is in progress, the punchline that produces humour is being delivered -- to their surprise and delight. Jokes don't translate well when you're in a group with mixed backgrounds: those whose first language is not English, those who might not understand a special term or an "in" expression, young people who wouldn't catch a reference to some bit of culture familiar to older people -- and vice versa . Never joke about another person in the group -- about their name, habits, hometown, profession, appearance, or past. It's not a question of whether the joke is cheery or appropriate. No one enjoys being singled out this way. When you are the subject of the joke, the laughter doesn't feel good no matter how hard you try to tell yourself they're not laughing at you. Because that's what it feels like. What do you say if you realize your joke upset someone? Apologize as briefly and as sincerely as you can, and hope that someone changes the subject. Try saying: "I'm sorry. I should have known better" or "I'm sorry. I wasn't thinking." What do you do if people don't get your joke or don't appear to find it as funny... Question: Which of the following best describes the writer's opinion on joke-telling? Answer:
OPTIONS:
- Nobody knows what makes a joke funny.
- We should not tell jokes unless we are asked to do so.
- Joke-telling is a very complex thing.
- Jokes should be told only to friends and family members.
Answer: Joke-telling is a very complex thing.

Question: Read the following article and answer the question. Article: They say that the real marathon begins at 35 kilometers -- the rest is just a warm up. And sure enough, in 2009, at around the 36 kilometer point of the Beijing Marathon I experienced what runners call "hitting the wall". I had been doing well until that point, but suddenly I felt a sharp pain in my leg. My pace slowed down dramatically and every brain cell in my head seemed to be screaming "stop!!!" The last 5 kilometers were not fun; in fact, they were really hard work. Keeping motivated to run those last few kilometers was one of the hardest things I had ever done. But that is what makes running a marathon such a rewarding experience -- if it were easy everyone would do it. I have to admit it is sometimes not even easy to find the motivation to get out of bed, pull on your running shoes and head out into the morning to go for another run. These last two weeks of training for the Muztagata climb have been a little tough. I have been following my training plan for about three months but now I find that my original enthusiasm has all been used up. Day after day of going to the gym is beginning to wear me down and there still seems so much longer to keep this up. I have begun to doubt that I am actually making any progress or getting any fitter and even thought that I might be going backwards! These are all very common experiences for people who are working towards challenging, longer term goals and I have learned to recognize these "highs" and "lows" in my energy and enthusiasm. Over the years I have learned a number of tricks that help me to deal with the days when my early motivation seems to have abandoned me for good.
