问题 (46)Your AAA computer also supports a second diskette drive that uses 5.25-inch diskettes, or 3.5-inch diskettes, depending upon the type of drive installed.
   There are two common types of disk drives: a hard disk drive (sometimes called a fixed disk drive) and a diskette drive (sometime called a floppy disk drive).(47)(Some models might not have a hard disk drive. ) With a hard disk, your computer can store large amounts of information (called files) in one convenient place. Using a hard disk, your computer can save and retrieve information much faster than with a diskette drive.(48).
   Each disk drive has a letter assigned to it, so you can tell your computer where to find information.(49)If you have a hard disk drive, it is called drive C.
    If your computer has a hard disk drive, drive C, then you can store your operating system and other programs on the hard disk.(50)If your programs and information files (data files) are well organized, then your computer can find and retrieve the information much faster. Check your operating system documentation for information about how to set a directory.
   If your computer has no hard disk, then you must use the diskette drive to load your programs and to store your information. Your operating system and application program documentation have information about using disk disk drives and making program diskettes and data diskettes.

     A. For example, if your computer has two diskette drives, one is called drive A, the other is called drive B.
     B. The hard disk drive is built into your computer.
     C. The key to using your hard disk effectively is the way you store your information.
     D. The 5.25-inch diskette is thin and flexible.
     E. The AAA computer comes with a diskette that uses 3.5-inch diskettes.
     F. A diskette drive uses a removable diskette, which has less storage space than a hard disk.
选项
答案A
解析 上文说，每个驱动器都被冠以一个字母，使你知道你可以到哪里去寻找信息。下文说，如果你有一个硬盘驱动器，则它被称作驱动器C。A句“例如，如果你的计算机有两个软盘驱动器，一个称作驱动器A，一个称作驱动器 B”，可以放在此处起到承上启下的作用。
