    One day, a university student{#blank#}4{#/blank#}(step) out of his office with a pile of books. He complained. “He always answers my questions with just a yes or no. However, he always gives me dozens of books and suggests me{#blank#}5{#/blank#} (find) the answer on my own.”

    By chance, the professor knew{#blank#}6{#/blank#}the student complained about. He explained to him with a smile, “This is the method I have learnt—the{#blank#}7{#/blank#}(hard) you work independently, the better solutions you will find. If you can make full use of the books, you will{#blank#}8{#/blank#}(probable) become a good lawyer in the future.”

    There are a few different stories behind the origin of the modern-day Christmas tree, although not all{#blank#}1{#/blank#}(root) in fact. Evergreen trees were {#blank#}2{#/blank#}(actual) used by people in winter festivals for thousands of years. During the winter solstice (冬至), evergreens signified the coming of spring. As Christianity spread throughout Europe, the trees began to be used as a symbol for Christmas. In mystery plays in Germany, they were often used as props (支柱){#blank#}3{#/blank#} (decorate) with apples to represent the Garden of Eden.

    One legend credits 16th century Protestant reformer Martin Luther for {#blank#}4{#/blank#}(bring) the Christmas tree into homes. Luther was supposedly walking through the forest on the night before Christmas when he looked up to see stars shine through the tree{#blank#}5{#/blank#} (branch). He was so dazzled by the {#blank#}6{#/blank#} (beauty) sight that he told his children it reminded him of Jesus and then put up{#blank#}7{#/blank#} tree in his own home.

    But it wasn't until the mid-19th century{#blank#}8{#/blank#}the Christmas tree as we now know it became custom. England's Queen Victoria encouraged her husband to decorate a tree as he had back at home in{#blank#}9{#/blank#} is now Germany. When a drawing of the royal family with their beautiful Christmas tree {#blank#}10{#/blank#} (appear) in a London newspaper, the tradition also became popular throughout the UK and US.

    Do you know that some of the most interesting urban gardens are in unexpected places? They may be on top of {#blank#}1{#/blank#} public building, in the middle of a commercial district, or in the terminal of one of the world1s {#blank#}2{#/blank#} (busy) airports. You may have wandered on a sidewalk next to a “secret garden”{#blank#}3{#/blank#} realizing it was just around the comer or on the other side of a wall.

    If you don t know these attractive {#blank#}4{#/blank#} (nature) spaces exist, you might never experience them. At the same time, the fact that these places escape notice {#blank#}5{#/blank#}(make) them worth seeking out.

    St. Dunstan-in-the-East is a historic church in London, which has a history of hundreds of years. It survived the Great Fire of London in the 17th century, but it {#blank#}6{#/blank#}(hit) by a German bomb during World War II. St. Dunstan was rebuilt in the 1960s. Later, the city turned the grounds into a public garden.

    St. Dunstan is on a quiet street, but it's only a short walk from major {#blank#}7{#/blank#} (tour)attractions like the Tower of London. This peaceful park reportedly gets {#blank#}8{#/blank#}(relative)crowded at noon on sunny days during {#blank#}9{#/blank#} time office workers from the nearby buildings come to eat lunch. At most other times, however, it's a quiet place {#blank#}10{#/blank#} (get) away.
