Nobody should ever be turned away from a church.I've always said that and have believed it,but I had to put it in practice the other night.It was my birthday,and we had a party at church,upstairs in the hall.My son Tim's roommate Garth sang in a great band,the Rooks,and they played for us.They performed wonderfully.

    Suddenly I noticed a man I'd never really seen before.He was big,never took off his coat or hat and stood in the middle of the room,looking a bit nervous.A homeless guy had just wandered into my birthday party,I thought.And I kept thinking about the guy who hadn't been invited,I meant to head over to him and politely asked him to leave. Wait a minute,I thought.Should anybody be turned away from God's house?Of course other uncertain thoughts crossed my mind: What if he was here to make trouble?What was under that coat?What if he was a terrorist?But some higher born qualities held sway."Hi,"I said,walking over to him."I'm Rick.This is a birthday party for me. Would you like something to eat?"He nodded his head.I got him a plate of food and told him he was welcome to stay. He nodded.He stayed there in the center of the room,smiling and swaying to the music.After a long time I looked for him again,and he was gone.

    I've always loved the parable（寓言）of Luke about the man who gives a big dinner and when no one comes,he sends his servants into the city streets to welcome the poor,homeless,disabled and blind.I don't know who invited this guy but I was glad he was there.I hope he had a good time.

Dear Dad,

    Today I was at the shopping mall and I spent a lot of time reading the Father's Day cards. They all had a special message that in some way or another reflected how I feel about you. Yet as I selected and read, it occurred to me that not a single card said what I really want to say to you.

    You'll soon be 84 years old, Dad, and you and I will have had 55 Father's Days together. I haven't always been with you on Father's Day but I've always been with you in my heart.

    You know, Dad, there was a time when we were separated by the generation gap. You stood on one side of the Great Divide and I on the other.

    The Father-Daughter Duel shifted into high gear ( 档位) when you taught me to drive the old Dodge and I decided I would drive the Chevy whether you liked it or not. The police officer who sent me home, after you reported the Chevy stolen, didn't have much tolerance for a stubborn 16 year old, while you were so tolerant about it, Dad, and I think that was probably what made it the worst night of my life.

    Our relationship greatly improved when I married a man you liked, and things really turned around when we began making babies right and left. Somewhere along the line, the generation gap disappeared. I suppose I saw us and our relationship as aging together, rather like a fine wine.

    But the strangest thing happened last week. I was at a stop sign and I watched as you turned the corner in your car. It didn't immediately occur to me that it was you because the man driving looked so elderly and fragile behind the wheel of that huge car. It was rather like a slap in the face delivered from out of nowhere. Perhaps I saw your age for the first time that day.

    I guess what I'm trying to say, Dad, is what every son and daughter wants to say to their Dad today. Honoring a father on Father's Day is about respect and sharing and acceptance and tolerance and giving and taking. It's about loving someone more than words can say, and it's wishing that never had to end.

    I love you, Dad.

Love,

Jenny

    Dogs are our best friends. That's especially true after a disaster, such as an earthquake. When buildings fall down, search and rescue dogs help find trapped people. Dogs' amazing noses can pick up the smell of survivors. Now scientists have developed an electronic tool that does the same thing. It's taking smell detection(探测) to a whole new level.

    The new invention is a sort of electronic nose, which can detect extremely low levels of many compounds(化合物) from people's skin. This isn't the first time engineers have developed such an object. Earlier models, however, have been bulky and expensive. They could not detect low levels of target compounds either. The new one is inexpensive and small enough to fit inside hand-held equipment.

    The electronic nose can detect extremely slight smell of more than one compound at the same time. "Being able to do this, in such a small object, is the significant discovery," says Sotiris E. Pratsinis, Professor of Process Engineering&Materials Science at the Swiss Federal Institute of Technology in Zurich. His team tested it in special spaces. They were like the small spaces where people might be trapped. Chemicals given off by the volunteers built up inside. The electronic equipment detected those compounds at unbelievably low levels.

The results were good news for the research team. But they may be not for our four-legged friends, who could soon be out of a job. "Ideally, this technology could replace search and rescue dogs," Pratsinis says.

    Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over dogs. Still, he thinks it may be too soon to have our trusty friends retire. He suspects, "I foresee that such an object could add to the fine work done by the dogs." Taylor also pointed out some potential limitations of the new invention. "E-noses are useful, but can be very likely to be affected by unstable readings and interruption," he says.

    You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet.

    That's why he created Lampbrella, a lamp post with its own rain sensing umbrella.

    The designer says he came up with the idea after watching people get wet on streets in Russia. "Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬) built into a street lamp," he said.

    The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors (传感器)then ensure that the umbrella offers pedestrians shelter whenever it starts raining.

    In addition to the rain sensor, there's also a 360 motion sensor on the fiberglass street lamp which detects whether anyone's using the Lampbrella. After three minutes of not being used the canopy is closed.

    According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each Lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground it would only be a danger for the tallest of pedestrians.

    While there are no plans to take Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department and insists this creation should be installed on the street where a lot of people walk but there are no canopies to provide shelter.

    Father's Day is celebrated today in 75 countries around the world. In my personal world, it's a day I like to think of my father's father.

    I learned a lot in my later life from my dad. But I learned something else, as a kid not even yet in school, from my grandfather. I learned to be curious. Little things fathers and grandfathers do can change the life of a child forever. In my case, this change came from necessity: My mom needed someone to look after little Allen, barely 4 years old, during the school day. My grandmother volunteered, and my grandfather came up with a way I could be watched while he worked in his clockmaker's shop.

    He seated me on a chair every day while I was there, right in front of his big workbench. He told me stories. He had a great sense of humor and a funny way of making a "buh-buh-buh" sound when he sensed my attention was weakening, and he encouraged me to ask questions about anything he was doing.

    Naturally, I was usually asking questions about clocks--what made the hands move, what the pendulum(钟摆) did, why you had to stop winding just before the weight hit the stop. Sometimes I just asked about which shiny parts went where.

    Most of all, he showed me how clocks worked. He treated me as if I were a sort of small grown-up. He never talked down to me, never told me I was "too young to understand".

    And so my grandfather granted me two things: A love of clocks, and an everlasting curiosity.

    As a journalist, I turned that fascination into explanations of why computers and software do what they do——and, perhaps even more importantly, why they fail at that task. I haven't been afraid of opening up the innards and looking for what is wrong with the computer.

    Police Officer Tidwell left the station just after 8 a.m. on Sunday June 4. He had spent a boring night on duty and was looking forward to his day of rest. By habit he took a short-cut down the path behind Dugby Hall road and after a minute or two he saw a man climbing down a drainpipe (雨水管)from an open bedroom window of Number 29. In silence, Tidwell crept into the garden. The man reached the ground and was dusting himself down when he felt his arm caught.

    "It's 8:15 on a Sunday morning," said the officer, "and this sort of thing seems an unlikely adventure at such a time. Would you mind explaining?"

The man was obviously scared but tried to keep calm. He said, "I know what you are thinking, officer, but it isn't true. This is a funny mistake."

    "It's part of my job to take an interest in unusual events. I think you've just left this house in a manner other than the customary one. That may be quite innocent, but I'd like to make sure." Tidwell took out his notebook and a pen. "Name, address and occupation and then, please, tell me your story..."

    "Charlie Crane, lorry driver, from Nottingham, 51 Breton Street. My story..."

    "Yes. What were you doing like a fly on that wall, Mr. Crane?"

    "Well, I had a breakdown yesterday and had to stay the night here. Bed and breakfast. The land-lady's name is Mrs. Fern. She gave me breakfast at seven, and I was out of he: mthe right way and down at the lorry by half past seven. Only when I felt around for a cigarette did I realize I'd left $80 in my envelope under the pillow here at number 29. I always put it under my pillow at night. It's a habit I've got into. I even do it at home...

    "I see. Why didn't you miss it when you went to pay Mrs.... What's her name?"

    "I'd paid her last night. You've got to pay when you take the room, see? So I came rushing back, but it's Sunday, and she'd gone back to bed, and could I wake her? I rang the bell and banged on the front door for ten minutes before I came round here to the back and spotted my bedroom window still open. Up I went, then, up this pipe. It's a trick I learned in the army. She didn't make the bed、and money was still there. You know the rest, I hope you believe it because... "

    "Mr. Crane, whatever are you doing here? I thought you'd gone an hour ago." It was Mrs.  Fem, speaking from the kitchen at the corner of the house.
