Ⅰ．阅读理解
Jose Alberto Gutierrez's life would never be the same again after finding a copy of Anna Karenina by Leo Tolstoy in the trash 20 years ago．It happened while he was driving his garbage truck through wealthier neighbourhoods at night and seeing books that were thrown away．It lit his desire to start rescuing books from the trash．He used to take home between 50 and 60 books every morning after his nine-hour shift that ran from 9 p．m．to 6 a．m．Eventually, he turned his book collection into a community library for children from low-income families．
Colombia's capital city of Bogota has 13 million residents and 19 public libraries．However, these libraries tend to be far away from where rural and poorer communities live．The option of buying new books is non-existent for families struggling to make ends meet．Gutierrez's library is true representation of how one man's trash can be another's treasure．Having access to a library of books and being taken away instantly to another world while absorbed in a book is a luxury for the kids．“I think we are simply a bridge between people who have books and those who don't have anything，” he said humbly about his remarkable attempt．
Gutierrez grew up poor, and his family could not afford to educate him beyond primary school．Nevertheless, his mother was an eager reader and read stories to him every night．Her love for books left a deep impression on Gutierrez, who never let a lack of formal education stop him from reading classics．He once said, “There's nothing more beautiful than having a book in your pocket, in your bag or inside your car．”
Today, his library, titled “The Strength of Words”， occupies most of his home, and is piled from floor to ceiling with fiction and non-fiction titles．He has also roped in his family to expand this mission．Mrs Gutierrez, for example, selects and repairs the books her husband finds．
As word began to spread about his amazing project, fifty-six-year-old Gutierrez earned himself the nickname “Lord of the Books”．In spite of all this, Gutierrez is not yet content to call it a day．He continues to search bins for reading material．
