In pairs, watch a TV programme or a movie and then note down expressions to attract someone’s attention and to tell interesting
news you find in the programme.
In pairs, read the following report and then answer the questions. Compare your answers with your classmates’.
C. Homework
FLOPPY DISK A floppy disk is a thin piece of magnetisable material inside a protective
envelope. The size of the disk is usually given as the diameter of the magnetic media, with the two most common sizes being 5.25 inch and 3.5 inch. Although both sizes
are called floppies, the name actually comes from the 5.25-inch size, in which both
the envelope and the disk itself are thin enough to bend easily. Both sizes of floppies are removable disks—that is, they must be inserted into
a compatible disk drive in order to be read from or written to. This drive is usually internal to, or part of, a computer. Inside the drive, a motor spins the disk inside its
envelope and a readwrite head moves over the surface of the disk on the end of an
arm called an actuator. The head in the floppy drive is much like that in a tape recorder. To record information, the head magnetizes a small area on the surface of
the disk in a certain direction. To read information stored on the disk, the disk controller—circuitry that controls the disk drive—directs the actuator to the location
of the information on the disk. The head then senses the direction of magnetization of a small area on the disk and translates this into a signal that gets stored in RAM
until the CPU retrieves it. Most floppy drives today are double sided, with one head on each side of the disk. This doubles the storage capacity of the disk, allowing it to
be written to on either side
Information is organized on the disk by dividing the disk into tracks and sectors. Tracks are concentric circular regions on the surface of the disk; sectors are
pie-shaped wedges that intersect each of the tracks, further dividing them. Before a floppy disk can be used, the computer must format it by placing special information
on the disk that enables the computer to find each track and sector.

In pairs, make dialogues based on the following situations.
1. You have found important information about a report you are doing from the internet. You are trying to tell your friend about it.
2. You have got two tickets to the computer exhibition. You are trying to tell one of your friends about it. You also want to ask her to company you to the exhibition.
3. You have some information on a new type memory. It runs faster than the previous model and it is cheaper. You tell your friends about this interesting news so they can
