Traveling by bicycle is a very popular means of transportation throughout China. China has a huge population, and it is said that there is at least one bicycle for every two people within the country. Of course, many people in China ride bicycles purely for sport or exercise, but it's also a much more commonly accepted means of everyday transportation, as compared to countries such as the United States.

    If you are living for a long period of time in China, chances are you will want to purchase your own bicycle so that you can use it whenever you want for transportation or just for the enjoyment of riding. Even if you don't use a bicycle for everyday transportation, owning one can be a great way of enjoying some of the trails in the rural areas, just for fun. However, if you are just visiting China, renting a bicycle can be a more convenient choice.

    It is important to choose the correct bicycle for your use. You'll find that in China, the one-speed style of bicycle is extremely popular. These bicycles are great if you want to ride around in the city to see the sights. They are quite comfortable and easy to ride. You can often rent a bicycle for an entire day for around $15.

    However, if you wish to ride on some of the rural paths, a mountain bike style would be a better choice. They are great for different kinds of road surfaces, providing for a safer ride. If you are planning to have a desire to tour and still be able to carry packages with you, then a touring bike would be the best choice. These are generally the most expensive to rent, but are extremely handy for carrying packages and even some of your luggage along with you.

    Mothers and daughters go through so much—yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother, Sheila Solomon Klass, both gifted professional writers, prove to be ideal co-writers as they examine their decades of motherhood, daughterhood, and the wonderful ways their lives have overlapped (重叠).

    Perri notes with amazement how closely her own life has mirrored her mother's: both have full-time careers； both have published books, articles, and stories； each has three children； they both love to read. They also love to travel—in fact, they often take trips together. But in truth, the harder they look at their lives, the more they acknowledge their big differences in circumstance and basic nature.

    A child of the Depression (大萧条), Sheila was raised in Brooklyn by parents who considered education a luxury for girls. Starting with her college education, she has fought for everything she's ever accomplished. Perri, on the other hand, grew up privileged in the New Jersey suburbs of the 1960s and 1970s. For Sheila, wasting time or money is a crime, and luxury is unthinkable while Perri enjoys the occasional small luxury, but has not been successful at trying to persuade her mother into enjoying even the tiniest thing she likes.

    Each writing in her own unmistakable voice, Perri and Sheila take turns exploring the joys and pains, the love and bitterness, the minor troubles and lasting respect that have always bonded them together. Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork. Perri admits that she can't sort out all the mess in the households, even though she knows it drives her mother crazy. Together they compare thoughts on bringing up children and working, admit long-hidden sorrows, and enjoy precious memories.

    Looking deep into the lives they have lived separately and together, Perri and Sheila tell their mother-daughter story with honesty, humor, enthusiasm, and admiration for each other. A written account in two voices, Every Mother Is a Daughter is a duet (二重奏) that produces a deep, strong sound with the experiences that all mothers and daughters will recognize.

    Flu easily spreads from one person to another. This is especially true to people who are weak. If you are weak, you are more likely to catch flu easily. Do you know how you can avoid flu?

    Keep in good health

    The best antidote (解药) to illness is good health. You can eat everything you want but make sure that your diet is healthy. The healthier you are, the better for you to avoid any type of illness around. Most doctors suggest plenty of fresh fruit juice and water in order that one can avoid flu.

    Stay away from people with flu

    If a member of the family or a friend has flu, stay away from them until they are well. Flu is very communicable and you can catch it by going with the person with flu. Wear a mask (面罩) and avoid using things that the person with flu is using.

    Exercise

    Exercising will make you stronger which means a stronger immune (免疫的) system too. Exercise often so that your body will keep healthy. It doesn't matter what kind of exercise.

    What is important is you are making your body stronger to prevent illness from attacking you.

    Be happy

    Happy people are healthy people. Their life is stress-free, so they are more likely to be safe from illness. If you are unhappy, which affects your immune system, you will easily get sick.

    Avoiding the flu is easy. Just boost (增强) your immune system and it will take care of the rest.

    Harvard University in the United States has been ranked as the university with the best “reputation” in the world.

    The Times Higher Education magazine has listed 200 top universities all over the world based on how they are regarded by a group of international college teachers. That is to say, the list measures how universities are regarded, rather than how they actually performed.

    “A subjective, word-of-mouth (口碑的) quality such as “reputation” has genuine economic value for universities,” said Simon Marginson, professor of higher education at the University of Melbourne in Australia.

    “Reputation is not just an impression, though it might not be as reliable as performance by objective indicators (客观指标),” said Prof Marginson.

    Based on the views of 13,000 college teachers around the world, it confirms the power of the big US universities, which dominate this list. Seven of the top 10 are US universities, headed by Harvard and Massachusetts Institute of Technology (MIT). Furthermore, 14 of the top 20 are from the US. Cambridge is the highest ranking UK university in the list, in third place, with Oxford ranked as sixth.

    “For students applying to university, reputation might be hard to quantify, but was an important part of the attractiveness,” said the president of Cambridge University's students' union, Rahul Mansigani.

    “Reputation makes a huge difference. If there is an idea that somewhere is great, it will get lots of good people applying whether it's true or not. Factors such as a sense of history and the presence of outstanding college teachers were part of the reputation of Cambridge,” he said.

    What do you do for fun in your spare time? Do you like reading? Do you often go to a book store? There is a store that is so different from others.

    The World's Smallest Bookstore, whose official name is just these three words, sits quietly about 100 miles northeast of Toronto.

    The bookstore is about 10 feet by 10 feet, so it is easy to imagine how tiny it really is. The bookstore is open 24 hours a day. Inside the bookstore are various books, especially literary books and classic authors' works. So if you are looking for something less popular, you may get a bit disappointed there.

    Another special feature of this bookstore is that each book only costs three dollars. All the expenses are paid on the honor system, which means buyers should make a note of what they've bought and leave their money by themselves. So the tools of the trade in this bookstore are quite simple: pens, papers, light bulbs and a label-maker.

    In order to catch passers-by's attention, the billboards (广告牌) of the bookstore are several times bigger than the store itself. With these large eye-catchers, many people are willing to stop by and have a visit.
