Cycling or even walking in city areas can be a little dangerous, thanks to the fact that one is sharing the road with vehicles that are increasingly getting larger and heavier. A recent study proves that of the 1.27million people that die in road traffic crashes each year, about half are walkers, motorcyclists and cyclists. Now there may be a solution that could provide at least some help to protect this helpless group—an airbag!

    If you are worried that this safety measure will involve you taking around a heavy package or worse still, wrapping yourself inside an ugly plastic bag, the bag is fitted not on the human, but on the outside of the vehicle. And, while there are several versions of the idea in the works, the one most recently unveiled by Dutch car company TNO, seems to be the most advanced and ready to go into production.

    In the works since 2011, the airbag covers only the lower part of the windshield. This will provide the much needed buffer(缓冲)between the person's head and the pane of glass he/she would otherwise meet.

The chain of events leading to an airbag cause are quite simple—A camera fitted beneath the rear-view mirror monitors the vehicle's closeness to a walker or cyclist. Any contact with either one of them sets off the sensors in the car's bumper and quickly blows up the airbag. In addition to that the sensors also set off the car's automatic brake, reducing the chances if an even worse injury.

    In tests conducted using a model, the success of not getting injured after being hit by a car travelling at about 40km/h was about 50-50! While not perfect, it will still result in reducing the number of deaths by a huge amount.

    With TNO ready to license its technology to car makers and many more companies trying to develop similar concepts, we would not be surprised if outer airbags become a standard feature in every car pretty soon.

    Next time a customer comes to your office, offer him a cup of coffee. And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea. The physical sensation（感觉）of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

    Psychologists have known that one person's perception（感知）of another's “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies' conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow's work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study's hypotheses（假设）, handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly,” says Bargh.

    A speech is a wonderful opportunity to inform,persuade or entertain.The best speeches often take on a combination of all three of these components（组成部分）.However,before you can go about the writing of a great speech,it is important to set goals.Goals keep you,your speech and your audience focused.

What a goal is

    In the context of a speech,a goal is the purpose of the speech,and what it hopes to accomplish.For example,the goal of a eulogy（颂歌）might be to celebrate the life of a loved one.The goal of a speech at a political gathering would be to inform the crowd about the political position of a candidate and persuade them to vote and campaign for the candidate in question.

    Why a goal is important

    Without a goal,a speech is without direction.The goal informs the structure and content of the speech.For example,if a speech's goal is to convince people that smoking is bad for them,the speech will be structured with persuasive arguments to back up the goal.A speech with a goal of informing audience will keep the information fair and factual.

    A goal is incredibly important to the speech's ability to connect with an audience.If the speaker is unaware of the goal of the speech,the audience will likely be unaware as well.This severely reduces the effectiveness of the message.

    Besides informing the audience of the content and structure,a speech's goal drives the speaker to greater heights. If a speaker is asked to speak on a specific subject but never establishes the goal,they won't know where to start in the research,organizing and writing of the speech.

    If you have been charged with delivering a speech,establishing a goal can seem difficult at first.There are several things to take into consideration.First,think about who you will be speaking to.The demographic（人口统计）of your audience will likely determine whether you will be able to persuade them or whether they will be able to sit through（一直坐到……结束）.Second,think about the topic itself.If the topic is something controversial（有争议的）,it may worth your while to consider an informative approach to present both sides of the issue.Finally,consider your resources.A speech with an informative or persuasive goal usually requires a great deal of research,and sometimes takes more time to write.

    When he was driving home one evening on a country road, Joe saw an old lady, stranded（抛锚）on the side of the road. He stopped in front of her car and got out. Even with the smile on his face, she was worried. He looked poor and hungry. He knew how she felt. He said, “I am here to help you, madam. Why don't you wait in the car where it's warm? By the way, my name is Joe.”

    She had a flat tire（轮胎）.Joe crawled under the car, changed the tire. But he got dirty and his hands hurt. She could not thank him enough and asked him how much she owed him. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the assistance he needed, and Joe added, “And think of me.”

    She drove off. A few miles down the road the lady saw a small restaurant. She went in. The waitress had a sweet smile, and was nearly eight months pregnant（怀孕）. The old lady wondered how someone like her who seemed poor could be so kind to a stranger. Then she remembered Joe. After the lady finished her meal, the waitress went to get her change from a hundred-dollar bill. But she stepped right out of the door.

    When the waitress came back, she noticed something written on a napkin, “I am helping you because someone once helped me. If you really want to pay me back, here's what you do—Do not let the chain of love end with you.”

    That night when she got home, she was thinking about the money and what the lady had written. She and her husband needed money with the baby due next month. She knew how worried her husband was, and as he lay sleeping next to her, she whispered, “Everything's going to be all right. I love you, Joe.”
