    I am interesting in spiders (蜘蛛), so this summer I watched them for quite long lime. Spiders don't look beautifully, but they have their own way of killing flying insects. They often build “bridges” between branch. They climb up a branch slowly, pulling some silk. Then they pull the silk towards another branch. When they built many “bridges”, they begin to form webs. As long as insects happen to touch the webs, no matter what hard they try, they can't escape. One day, there was a stronger wind, and the webs were broken, but the spiders still went on to building their “bridges”. They are not afraid with difficulties. As students, we should learn from it.

    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.

    I am building a tiny house. Not a dollhouse, but a livable space with bed, kitchen, storage-everything you'd need to live.

Why did I decide to build a house? I hoped it would give me skills that really matter in life, such as using tools for construction. And in building the house, I would understand how much labor goes into a home and truly appreciate what I am living in.

    But this past year, life gave me a heavy hit: My father, one of my best friends and my tiny house construction partner, died in a traffic accident.

    This is where my enthusiasm conics from now: the desire to finish my house for my father. Because of this decision, I now have some life experiences that some adults don't have. I can relate not only to people who want to build a house, but also to people who have lost a parent. And to all of them, I can say that giving up is not a choice.

    Still, without the help of my friends and family. I would probably stop my project. My friend Luke came to help the week after my father died; he knew I needed to get my walls up. The guidance from fellow tiny house builders and their families has been helpful. Putting windows in is no easy. And installing(安装) electricity is not something you do in your dreams. Ten hours of stabbing (戳) your fingers with metal string and getting shocked a couple times is not ideal.

    Sometimes when people get a hard knock, they stay down. I didn't. I didn't only want to show that anyone can build their own house; I also wanted to show that when I was handed lemons. I not only made lemonade. I made a delicious lemon cake.

    The vast majority of people can buy pretty much anything they need. Not anything they want, necessarily, but anything they need to achieve a satisfactory degree of creature comfort: clothing, water, shoes and food.

    During my childhood, a Michael Pollan book would have been the prize of my year, were I to find it waiting under my Christmas tree or open it upon my birthday. I also used to be thrilled at receiving necessary things, like simple socks or gloves, as present. Nowadays I have too many gloves. I purchase leather gloves online that appear to be a good deal or just because I like their look.

    Prosperity (富足) is a good thing, right? Yes, of course. But for me, I find that the greater ease with which such a generous gift is purchased, the less significance it has when given. This is why I try harder at gifts.

    My first line of dealing with this problem is simply understanding the effect of a little time spent. Even writing out a thoughtful or funny card goes a lot further than a “cute top” purchased from a popular shopping website.

    Need help? Go to your printer. There's paper in there. Fold one sheet in half and draw a heart on the front. Open it up and fill the card with a poem or a few words of your own. Not only is it obvious that you took the time to select your words and write them down, but now you force the reader to stop for a short time and consider what you were trying to accomplish with them. The effort made by the two of you is the gift.

    No matter how you decide to spend a little more time on your giving, the point is just quite simply that you do. You don't have to give a person a handmade paper boat to get a reaction. But you won't be sorry if you do.

    Now, if you want to be charming, then you'll need to build self-confidence, but becoming more outgoing is actually pretty easy. To get to a point at which you feel comfortable talking to complete stranger, follow these steps.

    Encourage your curiosity about people{#blank#}1{#/blank#}I wonder what his parents look like. I wonder what her favorite color is. Is he from around here? Is she the girl I saw at the movie theater last week? It will take some conscious effort, but you can't be outgoing if you don't care about people.

    Smile at others. Make it a goal to smile at one person a day. It can be anybody, and it can be the most subtle(微妙的) of smile. A quick glance paired with a smile---then run away if you want!{#blank#}2{#/blank#}Eventually, you will want to get to a point where you smile instinctively whenever you make first eye contact with someone.

    Ask people questions. The standard ”how are you?” doesn't really count, because people use it as a greeting rather than a real question{#blank#}3{#/blank#}This is where the curiosity and interest in others come into play.

    {#blank#}4{#/blank#}This is key to being a good conversationalist. If you don't make enough eye contact, the other person will feel invisible and the sense that you're elsewhere mentally. If you make too much, they'll feel uncomfortable. Is that specific enough for you?

    Note your body language{#blank#}5{#/blank#}To show that you're outgoing and welcome conversations, keep your body open, you head up, and a smile on your face. Resist playing with your phone or otherwise occupying yourself.

A. Master eye contact.

B. Never hesitate to smile at others.

C. Most of communication isn't verbal.

D. The more you do it, though, the less scary it will be.

E. Make eye contact when you're asking questions about people.

F. Wherever you go, try to observe people, and ask questions about them.

G. If you've already exchanged eye contact and smiles with someone, start off with a question,

    It is now mandatory(强制) for drivers or passengers to wear seatbelts while in a car in all states. In addition, it is also mandatory for kids of be in some kind of specialized car seat. Given the strict requirements in other vehicles, why don't buses have seatbelts?

    The main answer, at least for school buses, is that seatbelts do not make school buses safer. Overall, traveling on school buses is the safest way to travel—40 times safer than riding in a car—with only a handful of deaths occurring to passengers on school buses every year. The seats on the school bus are placed very close to each other and have high backs that are thickly padded. As a result, in an accident the students would be propelled forward a very short distance into a padded seatback that in a way is like an airbag. In addition, the fact that people sit high off the ground on school buses also makes it safer to travel on them.

    While school buses feature high backed seats and elevated seating locations, the same cannot be said of city buses. However, from a practical angle, there's little need to require seatbelts on city buses. Although the design of the modern low—floor city bus is less safe than the design of school buses, the fact that city buses rarely travel at speeds greater than 35 miles per hour means that any collision is likely to be small, Also, given that most trips on city buses are short and that many trips have standing passengers, the presence of seatbelts will make even less of a difference.

    Another answer why buses do not have seatbelts is cost. It is estimated that adding seatbelts to buses would add between $8,000 and $15,000 to the cost of each bus. In addition, seatbelts would take up room currently used as seats, meaning that each bus would have fewer seating places. The additional room in the bus taken up by seatbelts would mean that bus fleets would have to increase by as much as 15% just to carry the same number of people. Such an increase would be especially difficult in cities that experience overcrowding on their vehicles.

    Regardless of whether their passengers have seatbelts, all buses provide seatbelts for drivers and most bus companies make their drivers wear seatbelts in order not to be influenced by a collision.
