Home to me means a sense of familiarity and nostalgia(怀旧). It's fun to come home. It looks the same. It smells the same. You'll realize what's changed is you. Home is where we ran remember pain, live, and some other experiences; We parted here; My parents met here; I won three championships here.

    If I close my eyes, I can still have a clear picture in mind of my first home. I walk in the door and see a brown sofa surrounding a low glass-top wooden table. To the right of the living room is my first bedroom. It's empty, but it's where my earliest memories are.

    There is the dining room table where I celebrated birthdays, and where I cried on Halloween-when I didn't want to wear the skirt my mother made for me. I always liked standing on that table because it made me feel tall and strong. If I sit at this table, I can see my favorite room in the house, my parents' room. It is simple: a brown wooden dresser lines the right side of the wall next to a television and a couple of photos of my grandparents on each side. Their bed is my safe zone. I can jump on it anytime - waking up my parents if I am scared or if I have an important announcement that cannot wait until the morning.

    I'm lucky because I know my first home still exists. It exists in my mind and heart, on a physical property(住宅) on West 64th street on the western edge of Los Angeles. It is proof I lived, I grew and I learned.

    Sometimes when I feel lost, I lie down and shut my eyes, and I go home. I know it's where I'll find my family, my dogs, and my belongings. I purposely leave the window open at night because I know I'll be blamed by Mom. But I don't mind, because I want to hear her say my name, which reminds me I'm home.

    Students taking Georgia Tech's online Knowledge-Based Artificial Intelligence course received some surprising news. Jill Watson one of the nine teaching assistants(TAs) that had helped them finish the challenging course for the past five months was not a ‘‘she'' but an “it”—an intelligent robot!

    Watson is the brainchild of Ashok Goel, who teaches the popular online course. The Professor-of Computer and Cognitive Science in the School of Interactive Computing came up with the idea as a way to deal with a number of questions posed by students in the online forums(论坛). According to Goel, every time the course is offered, the 300 or so students that enroll post over 10,000 questions which are often repetitive. This led Goel to wonder if a smart robot would handle the questions which require standard responses.

    Having worked' with IBM's Watson technology platform in the, the professor knew it would be ideal for his artificial TA: Jill Watson. The artificial intelligence system that uses natural language processing and machine learning to analyze large amounts of data has even been cleverer than human competitors on the television show. It would therefore easily be able to handle routine questions that required little “thinking”.

    The professor and his team of graduate students began by populating Jill's memory with 40,000 questions and answers from past terms. Then came the testing stage. At first, Jill was not very good and often gave strange answers. It often got stuck on certain keywords. By the end of the semester, Jill had attained enough knowledge and skills to participate in forums without any management from Goel, or the other assistants.

    Parents in Spain are being urged to go on a weekend homework strike this month in protest against the unacceptable amount of after-school tasks their children are given.The homework load of Spanish children has long been a sore point with some parents,who argue that the burden is too great,places too much pressure on pupils and eats into family time.

    According to a study by the Organization for Economic Co-operation and Development (OECD),Spanish 15-year-olds have 6.5 hours of homework a Week compared with an average of 4.9 across the 38 OECD countries. The Spanish Confederation of Associations of Mothers and Fathers of Students (Ceapa) is calling on parents whose children attend Spanish state schools to boycott weekend homework in November.

    "We've lost a bit of common sense in this country when it comes to talking about education and we've got a system in which boys' and girls' free time has disappeared",said Jos Luis Pazos,president of Ceapa."Schools are passing on tasks to families that they shouldn't be.It starts with children from the ages of three to six doing half an hour's homework every day.For us,that's an unacceptable situation".

    Pazos said Ceapa disagreed with the belief that children should endure huge amounts of homework in the hope that it would ensure them a better future.They should be.happy when they're little and that life isn't just about someone telling you that you have to suffer inexplicably（难以理解地）.The model needs to change because society has changed.

    Schoolchildren have to fit their homework around the school day,which varies from region to region and school to school,but starts early from around 8 am or 9 am and finishes anywhere between 2 pm and 5 pm.However,schools are increasingly using an 8 am-2 pm timetable to save money and in the face of evidence that suggests the longer hours do not yield better results.

    A spokesman for the education department of Madrid said homework was a matter for individual schools rather than regional governments.They're the ones who know best what the need is in each case.

    Charity Cycling UK recently launched a campaign to raise awareness of dooring after discovering that many people don't know what it is. Dooring is when a driver or passenger opens the door into another road user—typically cyclist—without looking for other road users.

    Cycling UK chief executive Paul Tuohy told Gloucestershire Live: “Some people seem to see car dooring as a bit of a joke, but it's not and can have serious consequences. Cycling UK wants to see great awareness made about the dangers of opening your car door carelessly, and people to be encouraged to look before they open.”

    The charity says 2,009 of the 3,000 injuries were sustained by cyclists, resulting in five fatalities but says this might not be the full extent of the danger.

    Cycling UK says not all car dooring incidents will be attended by police, so the charity has written to transport minister Jesse Norman calling for a public awareness campaign urging all car occupants, not just drivers, to look before opening vehicle doors. One of the ways the charity suggests is the “Dutch reach”, where people leaving a vehicle reach over and use the non-door side hand to open the door.

    Cycling UK also suggests harsher laws and advice on safer road positioning for people who cycle.

    Mr. Tuohy said: “In the Netherlands they are known for practicing a method, known sometimes as the 'Dutch reach', which we think could be successfully encouraged in the UK.”

    “Cycling UK has written to the Department for Transport asking them to look into this, and highlight the dangers of 'car dooring' through a public awareness THINK style campaign.”

    If you're really concerned about opening a door into the path of a cyclist coming behind you, consider using what's known as the “Dutch reach” to open the door. That will naturally turn you in your seat and give you a much better view of what's coming up alongside in the car.

    Dreams are expressions of thoughts, feelings and events that pass through our minds while we are sleeping. People dream about one to two hours each night. We may have four to seven dreams in one night. Everybody dreams. But only some people can remember their dreams.

    The word “dream” comes from an old word in English that means “joy” and “music”. We dream in color. Our dreams often include all the senses—smells, sounds, sights, tastes and things we touch. Sometimes we dream the same dream over and over again. These repeated dreams are often unpleasant. They are bad dreams that sometimes frighten us.

    Artists, writers and scientists sometimes say they get ideas from dreams. For example, the singer Paul McCartney of the Beatles said he awakened one day with the music for the song Yesterday in his head. The writer Mary Shelley said she had a very strong dream about a scientist using a machine to make an animal come alive. When she woke up, she began to write her book about a scientist named Frankenstein who made a frightening monster(妖怪).

    In China, people believed that dreams were a way to visit with family members who had died. Some native American tribes(部落) and Mexican civilizations believe dreams are a different world we visit when we sleep.
