   Computer Assisted Language Leaming (CALL) materials come in two main formats: CD/DVD RO Ms and Web-based. Some are tailored to the content to be used in the classrooms whereas others can be used independently. CALL materials allow you to work at your own pace.
   Multimedia materials offer you the opportunity to take part in other computer-assisted activities, such as text-based gap-filling, multiple-choice and text reconstruction activities. Language teachers often develop such text-based CALL activities to accompany a particular course. CALL materials can be regularly updated.
   Because CALL learning activity types are usually designed from a template, they can sometimes be repetitive.
   A major advantage of CALL materials is that they offer instant feedback on your spoken or written performance. However, such feedback can be limited. If you are more interested in creating your own responses or elaborating on your ideas, you may find this type of Facebook frustrating. Web-based CALL materials can offer more variety through the use of hyperlinks, but feedback is still limited.
Just as representations of the cultures of the target language offered by courses using books; audio and videotapes can perpetuate stereotypes.

     Have you are wondered why soldiers are always clad in green? This is to enable them to camouflage themselves during wartime. Hiding in the jungles, their green attire blends into the surrounding trees and shrubs, making it difficult for the enemies to spot them.

        Long before man-made use of camouflaging, insects have already adopted the tactic of disguise to escape from the clutches of their predators. By having body colour close to those of the rocks and dried leaves, they can escape from being pursued by the predators.

       Butterflies and moths have developed a variety of camouflage strategies since they are quite defenceless and their predators are abundant. Possessing wings which resemble dried leaves help certain butterflies and moths to hide among heaps of dried leaves when predators are around.

   Fortunately, not all insects choose the art of disguise to escape from their predators; otherwise, the world would be so dull and colourless. There are insects which assimilate the bright body colours of bees and wasps to escape from being pursued by their predator. Long ago, birds have already learnt to avoid brilliantly coloured wasps and bees in fear of their painful stings. Hence, over millions of years, many harmless insects have assimilated the bees and wasps by imitating. their bright body colours and shapes. In this way, they appear dangerous and hence ward them off.

      The beefy, not only appears like the bumblebee in terms of body colour, even its hums sound similar too. The only difference is that the beefy does not have a stirring and is hence harmless. The hoverfly is another insect which imitates. the body colours of the wasps. Their bodies are striped yellow and black. The only deviations are that hoverflies do not have stings, and they have only one pair of wings each while wasps have two pairs each. These variations are hardly noticed by the predators and hence help them to escape.
