下面文章中有5处需要添加小标题。请从以下选项（  A、B、  C、D、E和F）中选出符合各段意思的小标题，并在答题纸上将相应选项的标号涂黑。选项中有一项是多余选项。

A. Find a fiction book. B. Learn how to read your card. C. Find your non-fiction book. D. Decide if you want to search by author, title or subject. E. Learn to find the card you need. F. Understand the Dewey Decimal System.

 
The card catalog was once found in every library. Most libraries have now replaced the card catalog with a computerized cataloging system. However, some libraries still have the set of drawers with thousands of cards inside, and some library patrons still prefer the hands-on approach to researching the information they need. Cards are set up alphabetically in long drawers. Different types of cards are kept separate from each other so you may search by author, title or subject. Learning to use the card catalog can help you find the book you want without waiting for a computer terminal.
Instructions:
1______
Once you have found the card for the book you want, write down the numbers and letters at the top of the card and the title and author of the book. The numbers at the top are how the book is cataloged using the Dewey Decimal System, and the letters are the first three letters of the author's last name. Your library will have the numbers at the end of the stacks (the shelves of books), so find the stack your book is located in, then scan the shelves of that stack until you locate the number on the card. More than one book can have the same number, so you will narrow down your search if you have the first three letters of the author's name.
2______
The cards in a card catalog reference other cards. An author card will also have a book title and subject, a title card will have the author and subject, and a subject card will have author and title. This is handy for cross-referencing, so if you want to read a book on beekeeping, you can look that up in the subject cards and find an individual card on each book the library carries on beekeeping.
3______
If you want to look up a book by Stephen King, find the author cards in your library's card catalog, and look under "K". The cards are organized by last name and are broken down into the individual drawers. Sometimes a letter will take up more than one drawer, so you may find drawers that have "Ka-Ke" and then "Ki-Kr." Stephen King will be in the drawer with "Ki-Kr." You would find a card in a similar manner by title or by subject by finding the drawer with the corresponding letters such as "Be" for beekeeping in the subject cards or "Wr" for "The Writer's Market" ("The" is not considered part of titles).
4______
This isn't required to use the card catalog, but it can make searching for your book a little easier. The numbers range from 000 to 999; 000-099 are general subjects, 100-199 are psychology and philosophy, 200-299 is religion, 300-399 is social science, 400-499 is language, 500-599 are natural science and math, 600-699 is applied sciences, 700-799 is art, 800-899 are literature and plays, and 900-999 are geography and history.
5______
The author card will have a call number at the top, a line with the author's name with last name first, then lines for the title of the book, its publisher, a brief summary and subject listings. For an author with many books like Stephen King, there will be a card for each of his books in alphabetical order. Title cards are similar but have the title first, then the author in the following line. Subject cards have the subject in all capital letters at the very top of the card and the same information as on an author's card. Many cards on the same subject will be organized by the authors' last names.

第四部分 任务型阅读 (共10小题；每小题1分, 满分10分)

    请认真阅读下列短文, 并根据所读内容在文章后表格的空格处里填人最恰当的单词。注意：每个空格填1个单词。

There’re seven oceans across most of the earth's surface. But they contain saltwater, unfit for human consumption. Only a tiny part of the world's water – about 2.5 percent – is drinkable. That still would be an enough supply if it were clean and available where needed. However, it's not.

Today some 1.2 billion people lack access to safe drinking water and 2.6 billion lack proper waste water treatment. As a result, polluted water supplies are blamed for the worldwide deaths of 1.8 million children, according to the United Nation's Human Development Report for 2006.That means 4,900 children under 5 years old died per day.

What's more, children worldwide miss 443 million days of school each year because of water-related illnesses. The UN also estimates that half of the world's hospital beds are occupied by patients suffering from water-borne diseases.

Beyond that, millions of people (almost always women) in different parts of the world spend hours per day carrying water up to several miles for their family's needs because no source is close at hand.

Since 1992, the UN has sponsored(倡议) World Water Day, observed on March 22, to raise awareness of the need to protect and improve access to clean water supplies. 

"When the well is dry, then we know the worth of water," said Benjamin Franklin, long before today's water challenges.

It's clear that competition for water "will intensify(加剧) in the decades ahead," said Kemal Dervis, administrator of the United Nations Development Program in its 2006 report. "Water is the fundamental resource, crossing borders through rivers, lakes – a fact that points to the potential for cross-border tensions in water-stressed regions."

Growing populations, are using up water resources, and climate change is expected to worsen the problem as it changes rainfall patterns. A new UN study shows that as temperatures have gone up, the world's glaciers(冰川) have been decreasing at fast rates and may disappear entirely within a few decades. China, India, and the West Coast of the United States are among populous places that rely on glaciers for their water supply. Glaciers feed some of the world's great rivers, which serve billions of people.

One of the UN's Millennium Development Goals, established in 2000, is to cut in half by the year 2015 the population unable to reach or afford safe drinking water. Achieving that goal is "critically important," says UN Secretary-General Ban Ki Moon. "When you look at the health and development challenges faced by the poorest of the world's population, the common sticking point often turns out to be water." Governments and private groups are working hard to solve the problem as well.
