Buying books on the Internet is a great way {#blank#}1{#/blank#} (save) time and money. Online bookstores offer not only new books but also used books. What's more, they are far better {#blank#}2{#/blank#} (compare) to traditional bookstores as they offer much broader kinds of books. Another advantage of shopping online is that you can also read the book reviews as well as readers' reviews to get an idea {#blank#}3{#/blank#} the book is worth buying. Online bookstores often offer great discounts to{#blank#}4{#/blank#} (attraction) book lovers with a tight budget.

    For book lovers, {#blank#}5{#/blank#} is important to get books in time, in which case they need to find a {#blank#}6{#/blank#} (rely) online bookstore that is able to provide fast deliveries.

    Here are some {#blank#}7{#/blank#} (advise) for reference when you are selecting an online bookstore. Some online bookstores are popular {#blank#}8{#/blank#} fiction books; some are for non-fiction books or novels, etc. Understanding their specialization will help you to get the right kinds of books in time. Never choose stores that offer {#blank#}9{#/blank#} (believe) cheap prices, as books that {#blank#}10{#/blank#} (sell) at such low prices could be in very bad condition.

    In the West, some people believe that personality can be predicted according to the blood type {#blank#}1{#/blank#} the person was born with. People with blood type A, for example, {#blank#}2{#/blank#} (consider) more likely to be serious, hard-working, and quiet, while people with blood type O are likely to be popular and outgoing, yet often unable {#blank#}3{#/blank#} (finish) what they start. Though this belief continues to be strong, some people question whether it is true.

    The blood-type personality theory {#blank#}4{#/blank#} (start) in Japan in 1927 when Furukawa Takehi noticed personality similarities and {#blank#}5{#/blank#} (different) among his workers. This idea soon went out of fashion, {#blank#}6{#/blank#} it was brought back by a Japanese television host named Toshitaka Nomi in the 1970s. The belief is still strong in Japan and is increasingly popular in neighboring countries. Most Asians might believe {#blank#}7{#/blank#} the blood-type theory, but for many it seems {#blank#}8{#/blank#} (harm) and not something to be taken too seriously.

    Is the belief true? The scientists in Asia largely dismiss (摒弃) the belief as a modern-day superstition (迷信). Most studies have failed to find any strong {#blank#}9{#/blank#} (connect) between blood and personality. {#blank#}10{#/blank#} (general), scientists warn against making predictions or important decisions based on this questionable theory.

    When Mr. Wang, a Chinese calligraphy(书法)master and painter, invited me to his studio, I got extremely{#blank#}1{#/blank#} (delight) . What a treat!

    His apartment doubles as his studio, {#blank#}2{#/blank#} he creates calligraphy works and paintings as well. The living room has a long desk with a collection of{#blank#}3{#/blank#} (brush) of varying sizes, two big ink pots and a pair of paper weights.

    Mr. Wang showed his latest work, a scroll(卷轴)of the Great Wall at Badaling {#blank#}4{#/blank#} (wind) its way along the steep hills, which {#blank#}5{#/blank#} (recognize) as a World Heritage Site by the United Nations in 1987. The beauty of the seven-meter-long scroll painting was beyond {#blank#}6{#/blank#} (describe).

    He told me someone had offered a large amount of money for the painting, but he refused {#blank#}7{#/blank#}(part) with it as he wanted to donate to the National Museum.

After that, Mr. Wang invited me to practice calligraphy, and it was the first time that I had {#blank#}8{#/blank#}(true) experienced the beauty of the line. It was then{#blank#}9{#/blank#} I noticed Mr. Wang appeared to have a healthy body. I wondered if practicing calligraphy kept him so fit. Whether that is true, one thing is certain; as Mr. Wang put{#blank#}10{#/blank#}, "Only do one thing and do it well—that's the secret to success"

    A CCTV journalist succeeded in arousing a heated discussion among netizens by asking people whether they were happy. The responses to the question were various, even some quite funny ones {#blank#}1{#/blank#}(include). Although people played jokes {#blank#}2{#/blank#} the answers, it did not take long {#blank#}3{#/blank#} they began to figure out the true meanings of happiness.

    It is certain that people's views on happiness {#blank#}4{#/blank#}(affect) greatly by their own life experience. Unfortunately, too many people refer to being rich as happiness and there is no sign of {#blank#}5{#/blank#} decrease in the number of those who are voluntarily at the mercy of wealth. Some people whose {#blank#}6{#/blank#}(intend) is to make big money appreciate {#blank#}7{#/blank#}(be) given any chance to multiply their income, believing that is {#blank#}8{#/blank#} their happiness lies. Some are eager to inherit their parents' property, especially those who are known as silver-spoon kids. Even worse, some would rather break the law to satisfy their financial desire or seek their fortune {#blank#}9{#/blank#}(legally).

    In my opinion, happiness is not about pursuing wealth merely but about admiring the beautiful things in life. Therefore, live your life {#blank#}10{#/blank#} the fullest and be happy.

    "Failing to open curtains fully makes people more likely to get sick", {#blank#}1{#/blank#} new study suggests. It found sunlight kills disease-causing bacteria {#blank#}2{#/blank#} live in dust, while darker conditions let them thrive (繁殖). The findings {#blank#}3{#/blank#} (publish) in the journal Microbiome.

    Researchers {#blank#}4{#/blank#} (warn) the problem also affects windowless offices. Study leader Dr. Ashkaan Fahimipour said: "Humans spend most of their time indoors, where dust carries bacteria {#blank#}5{#/blank#} (make) us sick.

    "Therefore, it's important {#blank#}6{#/blank#} (understand) how the buildings we live influence dust eco-systems and how this could {#blank#}7{#/blank#} (serious) affect our health."

    His team at the University of Oregon chose 11 small rooms and allowed in {#blank#}8{#/blank#} (differ) levels of sunlight. After 90 days, dark rooms had double the number of bacteria able to reproduce. Fahimipour added: "We hope that with {#blank#}9{#/blank#} (far) understanding we can design access to daylight in {#blank#}10{#/blank#} (build) schools, offices, hospitals and homes in ways that reduce the risk of dust-borne infections."
