If you don't think technology can improve your trip better, meet Judy. When she recently checked into the Biu Hotel in Zurich, a clerk asked her to pay hundreds of dollars higher than the online offer. It was not a cheap stay, but it became more of one after she fired up the Booking. Com app she'd used to purchase her room on her smartphone. “As soon as I showed him the rate, he honored it,” Judy says.

    Technology may create challenges for travelers-indeed, it may have led to Judy's rate confusion in the first place-but it can also solve them. The solutions go beyond making sure of a hotel rate. The latest version of Booking.com is among the most feature-rich booking programs. Users can select hotels by location, make a secure booking and view the confirmed rate.

    Another pain point for travelers is traffic that eats away precious vacation time. There's a new app for that, called Commute. As the name implies, it's aimed at users who have to make the same trip every day. Just input basic information about your destination and expected leaving time, and the app will start sending you traffic data 15 minutes before you leave.

    Another source of travel-related conflict and confusion is money. That's particularly true when you're dealing with a foreign currency. The latest version of Travel Money Tracker helps travelers prevent currency mix-ups. It instantly converts(兑换) a country's native currency to yours, so you know exactly how much that Espresso(浓咖啡) in Milan costs in dollars. One extra feature is the ability to set up an alert that tells you when you're overspending, which can sometimes be a problem when you're on vacation. The only catch, of course, is that you have to remember to record all your purchases.

    Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?

    Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbacks (平装本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.

    Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia, though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books, science textbooks, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.

    A complaint was received by the president of a major car company:“This is the fourth time I have written to you , and I don't blame you for not answering me because must sound crazy, but it is a fact that we have a tradition in our family of having ice-cream for dessert after dinner each night. Every night after we've eaten, the family votes on which flavor(味道)of ice-cream we should have and I drive down to the store to get it. I recently purchased a new Pantsmobile from your company and since then my trips to the store have created a problem. You see, every time I buy vanilla(香草)ice-cream my car won't start. If I get any other kind of ice-cream, the car starts just fine. I want you to t now I'm serious about this question , no matter how silly it sounds: What is there about a Pantsmobile that makes it not start when I get vanilla ice-cream, and easy to start whenever I get any other kind?'

    The Pantsmobile company president understandably doubted about the letter, but he sent an engineer there anyway. The engineer had arranged to meet the man just after dinner time, so the two got into the car and drove to the grocery store. The man bought vanilla ice-cream that night and sure enough, after they came back to the car it wouldn't start for several minutes. The engineer returned for three more nights. The first night, the man got chocolate. The car started right away. The second night, he got strawberry and again the car started right up. The third night he bought vanilla and the car failed to start.

    There must be a reason why the man's car wouldn't start when he bought vanilla ice-cream. What was it? After doing more research into the case, the engineer eventually found out. The cause. Vanilla ice-cream was the most popular flavor and was on display in a little case near the express check out, while the other flavors were in the back of the store and took more time to choose and check out. This mattered because the man's car was experiencing vapor(蒸汽) lock, which is excess(过度的)heat boiling the fuel in the fuel line and the resulting air bubbles (气泡) blocking the flow of fuel until the car has enough time to cool. When the car was running, there was enough pressure to move the bubbles along, but not when the car was trying to start.

    There are some strange driving laws in different countries.

Even though they're not the most exciting things in the world, plants have fascinated us ever since the days of early humans. They may not do any tricks or greet us when we come home at night like a dog would, but that doesn't mean they're any less interesting than animals.

However, just when we thought we knew everything we could about them, a recent study found that plants may possess a secret ability that's gone unnoticed all this time. According to the study by Australian biologist Monica Gagliano, published in the journal Oecologia, plants may be able to hear sounds.

To come to this conclusion, Gagliano and her team planted pea seedlings in a pair of different Y-shaped pots with two arms. The first pot's arms led to fresh water, while the other's led to either dry soil or a sealed plastic tube containing flowing water.

Naturally, the first pot's seedlings grew toward the water. What's surprising, however, is that the second pot's seedlings grew toward the sealed water supply and not the soil.

They just knew the water was there, even if the only thing to detect was the sound of it flowing inside the pipe, Gagliano told Scientific American. Gagliano believes that plants are able to use their leaves to detect sound waves, which make tiny vibrations (振动) as they're produced.

This could explain why so many people believe that singing or playing music to their plants helps them grow.

I had a plant that I used to wash the leaves once a week and sing to it, plant lover Heather Goodall told BBC News. It grew from being about 2 feet tall to 7 feet tall in just a couple of years.

So, does this mean we should start treating our plants like pets? Not necessarily, although perhaps it does mean we should give them more respect. I would like to see plants acknowledged more as the amazing, interesting, exotic living beings they are, and less as a mere source of human nutrition, Fatima Cvrckova, a scientist at Charles University in the Czech Republic, told BBC News.
