Founded in 1764 by French traders, St. Louis today is the fifteenth largest urban area in the United States. There are many attractive destinations for tourists.

American Kennel Club Museum of the Dog

    Dog lovers who visit St. Louis won't want to miss this 14,000-square-foot museum. Inside are over 500 paintings, prints, watercolors, and a variety of other dog art objects.

    The Museum is open year round, Tuesday through Saturday 10 AM to 4 PM, and Sunday 1 PM to 5 PM. Admission is $ 5 for adults, $ 2.50 for seniors, and $1 for children up to 14.

Anheuser Busch Brewery

    The Anheuser Buxch Brewery tour is not just for beer lovers. The tour includes the historic Brew House. Then the tour continues to the modern Bevo Packaging Plant. The best will be the Budweiser Clydesdale stables. The tours are always free.

Gateway Arch

    Designed by Eero Sarinen and Hannskari Bandel, it took over two years and 900 tons of stainless steel to build. It is the tallest of the country's National Monuments. The Arch is part of the Jefferson National Expansion Memorial. About one milion people per year come to the top of the Arch, where there is an observation platform providing a great view of the city.

St. Louis Zoo

    First version of the St. Louis Zoo opened in 1904 at the St. Louis World's Fair, but in the century since it has grown into one of the chief zoos in the world. The passenger train takes visitors around the Zoo, which contains over 9,000 animals of over 800 species.

    The Zoo is open every day but Christmas and New Year, with summer hours of 8 AM to 7 PM, and hours the rest of the year of 9 AM to 5 PM. Admission to the Zoo is free.

    Introductory Chemistry was taught at Duke University for many years by professor Bonk. One year, two guys took the class and did pretty well on all the quizzes and mid terms. They each had a solid A. These two friends were so confident in going into the final that the weekend before finals week,despite the Chemistry final being on Monday,they decided to go to the University of Virginia to party with some friends.

    They had a great time there. However,with their hangovers(宿醉) and tiredness,they overslept all day Sunday and didn't make it back to Duke until early Monday morning. Rather than taking the final then,they found professor Bonk after the final and explained to him how they missed the final. They told him they went up to the University of Virginia for the weekend and had planned to come back in time to study,but they had a flat tire on the way back and didn't have a spare. So they were late getting back to campus.

    Bonk thought this over and agreed that they could take the final the following day. The two guys,happily and relieved,studied that night and went in the next day at the time that Bonk had told them. He placed them in separate rooms and handed each of them a test booklet. He told them to begin.

    They looked at the first problem which was something simple about solution(溶解).It was worth 5 points. "Cool," they thought,"this is going to be an easy final". They then turned the page. They were unprepared,however,for what they saw on it. The question contained only two words: (95 points) Which tire?

    Boston Tourist Attractions and Sightseeing

    Duck Tours

    One of the most popular tours in and around Boston are the legendary Duck Tours, which show you the best that the city has to offer. World War II vehicles take you on a scenic drive around the most famous sites and attractions in the city. With interesting explanation, this novel tour is an enjoyable and fun way to see the city and very much recommended.

    New England Aquarium

The aquarium is home to over 7,000 fish and a collection of many different sea creatures. The city's most visited tourist attraction is complete with exhibit space, gift shop and a cafe with spectacular views of the city and harbor. It also offers whale-watching tours with indoor and outdoor seating — and even seal or walrus (海象) shows.

    Boston Public Library

    Built in 1848, the Boston Public Library was the first free publicly supported city library in America. With more than 650,000 photographs, 100,000 prints and 250 different papers in the “Newspaper Room” the library now has Internet access, two restaurants and an on-line store with reproductions of its priceless artwork. All exhibits are open to the public and books m only the beginning.

    Bull and Finch Pub - Home of Cheers

    This world-famous pub is the inspiration for the hugely successful sitcom (情景喜剧) “Cheers”. Although the outside is the same as on television, the inside is completely different. However, although unexpected, this is not a real disappointment as the busy pub is full of reminders of Cheers. The menu serves typical bar food, and is very popular with tourists

    If visiting family or staying at one of the luxury Boston hotels downtown, you may want to corner purchasing a “Boston City Pass” as this will enable you to pay half price for most the finest attractions.

    In 1994 I wrote a letter. I stuck it in an envelope, put it away and completely forgot about it. It wasn't until we moved into our new home in 2006 that I found it again. It was addressed to me with explicit instructions not to open until my birthday 2005. It was now 2006 so I decided to open it. This is what it said: Dear Sherri.

    By the time you read this you will be 30. At the age of 18 I had so many hopes and dreams about where you'd be, what you'd be doing and with whom you'd spend your life with.

    Right now I hope that you have traveled and seen everything you've always wanted to, both in Canada and overseas, and maybe even settled down somewhere in Australia doing some research in the field of biology (genetics).I hope you're married to the man of your dreams. The man of mine is Gwynn. He is originally from South Africa (another place I wish to visit).

    However, if things don't go according to plan for you, I wish you all the love, happiness and joy in the world and don't settle for anything less than the best since that is absolutely what you deserve.

    Live long, be happy and live life to it's fullest.

    Love Sherri "18"

    When I read this for the first time since writing it I was floored. Even now having dug this up again another 4 years later I still can't help but think this is really cool. So much of what I wanted for myself has materialized. I did travel to a few more places in Canada although I haven't seen everything I'd like to.

    I did marry the man of my dreams and yes he still is my one and only. I lived in Australia for nearly 4 years, I had a career in Biology in the field of genetics for 10 years. I have two lovely kids I have not one dog but two dogs. Gwynn is a computer programmer.

    I suppose these were things that I really did want. Having never strayed too far from home overseas travel was a huge deal. Having never been away from my family moving to Australia for several years was an huge decision. I find it fascinating how the dreams of a young and naive little girl can become a grown woman's reality.

    How about writing a letter now to yourself in, say, 10 years from now? It's an interesting experiment.

    If you cannot afford to travel in any class above economy, flying generally sucks, either a little or a lot, depending on your tolerance level. But it especially sucks if you are too wide for the airline's design.

    Just getting to your seat can be a challenge, as your hips (臀部，髋) bounce from seat to seat on each side of the aisle (过道). If someone is standing up to put things in the overhead locker, there is a decision to be made about whether it's worth trying to squeeze past. Everything is just slightly too small: the seats, the overhead lockers, even the bathrooms—and those, it seems, are getting even smaller.

    The Washington Post recently reported that, on some newer planes flown by American, Delta and United airlines, the bathrooms in economy class are just 61cm wide: about 25cm narrower than the average portable toilet, and roughly the width of the average dishwasher. Your face might be the only thing you can poke in there comfortably—which makes it a poor design, considering what a passenger is likely to need the bathroom for.

    According to the manufacturer, these "Advanced Spacewell" bathrooms make space for six additional passengers, which is great for the airlines' financial bottom line. But what about the other bottom line? Concerning, well, bottoms that can't fit into their planes' bathrooms?

    As bodies get bigger and aeroplane spaces get smaller, the wide among us have come up with solutions. Armrests that turn us into sausages (香肠) can be pulled up, or slowly encased (围住，包起) into the soft flesh of our sides until we go numb (麻木). We can ask the flight attendant to get us a seat-belt extender, if security has confiscated the one we brought with us, as can sometimes happen. But squeezing into a tiny toilet and closing the door behind us? Not workable.

    Unlike the impossible task of squeezing down the aisle to your seat, or the side-to-side dance necessary to get big hips past the armrests, fitting into a space just 61cm wide is not just a challenge—it is almost impossible. It is not like missing out on an option for the in-flight meal—a bathroom is as essential as a safety-compliant seat belt, or the air that is pumped in to the cabin (飞机舱). If airlines are not willing to make space for us, bigger passengers may have no option but to reconsider booking a flight at all.

As the pandemic makes clear, cities are possibly humanity's greatest invention, but cities with huge populations also make us easily suffer from the rapid spread of disease. Yet humans aren't the only species that face this problem. Honeybees have lived social lives for tens of millions of years, making them some of the most experienced in the battle against infection. And over time, natural selection has given them quite a few impressive strategies for reducing transmission within bee groups.

However, these strategies are not enough to prevent every threat. Honeybees are battling their own global disease, for which they were totally not prepared. A parasitic mite (寄生螨) originally existed only in the groups of Asian honeybees, but later jumped to infect Western honey bees. Today, it has spread to every region where honeybees are kept except Australia and a handful of remote islands, quickly becoming a global disease of the bees.

If left untreated, a group of bees will typically die from the mites within two years. These infections, plus farm chemicals and poor nutrition, have forced beekeepers to struggle to keep their bees alive. Of the 2.6 million honeybee groups in the US, over half of them have parasitic mite.

And that's only the count of those bees that are tested and reported; the actual numbers are likely much higher. Beekeepers have still managed to slowly increase the number of groups they keep, on average, but at a much higher cost.

Western honeybees did not grow with parasitic mite, and the Western bees lack the behavioral features those Asian honeybees have, like permanently burying the members infested by parasitic mite and, perhaps the most extreme strategy, where the bees are so sensitive to parasitic mite that they completely die as soon as infected, sacrificing themselves to prevent the mite from reproducing.
