Ever get that feeling you're being watched? Well, if you're a dog-owner, you may have a point. Dogs are able to watch people's interactions with one another to determine who holds yummier treats, according to a new study. This study joins others that show dogs are good observers of human behaviors and feelings. It offers evidence that dogs use information not only from people's direct interactions with them, but also their interactions with one another. In the study, dogs watched a man ask two women for some of their corns. Both women gave the man corns when he asked, but in response to one woman, the man showed his enthusiasm and said the corns were so delicious. In response to the other woman, he gave the corns back and called them _ (in Spanish;the study was conducted in Argentina). After these interactions, the man left and an assistant holding the dog let the dog go. While many dogs didn't approach either woman, the dogs that did have a preference tended to prefer the woman with the yummier food. Other studies of dogs' people-watching ability have found dogs are able to tell the difference between happy and sad faces in their owners. They prefer people who give others food when asked over people who don't give others food. And in one study, dogs turned toward crying people more often than toward talking people. So how much do dogs really understand about the humans around them? That's not totally settled yet. In a strange twist to the Argentine study above, when the researchers tried an experiment in which they put two plates of corns on a table and had a man react to each plate, dogs didn't preferentially approach the tastier plate afterward. You could say dogs watch for the interaction between two persons, not just how a person reacts. Yet a previous study found dogs will choose boxes that people reacted to happily, but not boxes people reacted to with a disgusted face. Well, either way, you can be sure Fluffs is keeping an eye on you, to the best of her ability. The study was published in the journal... Which is one of the procedures of the Argentine study? A) The man had different reactions to the food received. B) One of the women didn't give the food to the man. C) The assistant accompanied the dogs to get the food. D) Many dogs went to one of the women.

When I grew up, all the schools in the village demanded that girls cut their hair. The teachers would measure our hair and make sure it was not too long. I remember crying and begging as the scissors cut my hair. My dad told me that a girl who was in school needed to concentrate on books and that hair was a distraction . I cut my hair all the way through primary school and middle school. Then I went to a high school that allowed long hair but no styles or braids during class hours. Even then, still adhering to my dad's words, I never wore my hair long. When I graduated from high school, I started growing my hair. I spent hours looking in the mirror and shaping my hair. My sister complained, wondering why I had to have two styles in a day. In college I heard the word perm . Girls had some strong chemicals put on their heads and made the hair look beautiful. I quickly sat in a salon and changed my hair. I returned to the salon once every month. Even during the days when I had no money for food, I had to find money for my hair. After college, I was jobless and broke. I had to have my hair cut. At that time I saw a bald black model. Her style shocked me and I admired her so much that I began to follow her.

Ques: People were hanging out of their apartment windows screaming down at me,"Just give up,you fool! You'll never make it with that little bike."I kept telling them repeatedly,"All I have is this three-wheeled tricycle."I kept tipping to the side,but I kept my balance and ignored the people who were making fun of me. Then at one point a man left his home and ran out into the middle of the street. "This bike will take forever at the speed you're going!" He continued screaming words of discouragement right in my face. I replied,"I must push forward;I must get to the finish line! " I held on as tightly as possible and rode straight ahead with great determination. I had unshakable faith that I would make it! I also knew it did not matter how long it would take,because I knew it was worth it. At that point,the dream came to an abrupt end I got up and remembered the dream very clearly.

London-Lazy students can now give up on work altogether as two Oxford University students have made scores of A-grade essays on the website for students to copy. The essays are on the new website, "revise.it" The website includes an "EssayLab" designed to make cheating as effective and effortless as possible. Its homepage announces to surfers : "The revise.it EssayLab is a bank of hundreds of A-Level essays covering popular topics." "Next time you are asked to write an essay, why not see what we have on the subject-if you are in a lazy state of mind you can even use our guide to writing the essays and then just hand them in." Nick Rose and Jordan Mayo, both 19 and first from Manchester, spent much of their first year as students at the university setting up the website. There is no charge for downloading the essays. "I have never been very good at essay writing," Rose admitted. "We don't see essay bank as a cheating way. It's a surprising valuable resource. You can learn a lot by reading other people's work on the subject." Among other tips, the website suggests inventing important speeches to give essays extra weight: "Popular people to quote are Douglass Hurd or Disraeli." Hurd was a foreign secretary in the 1980s and Disraeli was a 19 century prime minister. Teachers are expressing their opinions by e-mail that they are angry about the website that "encourages students to cheat", but students disagree. According to Rose: "Exams are a fight. It's us against them." It can be inferred from this passage that _ . A) students who visit the website "revise. it" are all lazy B) students in Oxford University are all lazy C) websites in Oxford University are all set up by students D) websites can provide people with different kinds of information
