One of the foremost responsibilities of language teachers should be not just to let students to acquire set phrases, but also to teach how to interact in a variety of situations, to develop and practice new language and behavioural skills in a relatively safe setting. In recent years, there has been a growing interest to integrate meaningful use of language and rich authentic communication in English classes. Yet, one of the universally effective methods in the classroom, which meets the demand of all above requirements, is a role play. In the present article the attempt is made to investigate the effectiveness of the role play in English classes of an intermediate level.

SUMMARYThe expression of the virulence character in the virulent line (YM) ofPlasmodium yoelii yoeliiwas investigated. The level of virulence was measured by counting the parasitaemia of the mature red blood cells. Several sub-clones were isolated from the virulent line YM and each was tested for its level of virulence. Out of 10 sub-clones 1 showed a marked decrease in virulence. However, transmission of this sub-clone through mosquitoes fully restored its virulence. A clone isolated from the progeny of a cross between mild and virulent parents had an intermediate level of virulence. A sub-clone isolated from this intermediate virulent line exhibited greatly reduced virulence. Mosquito transmission of this sub-clone also restored its virulence to a level comparable with the virulent line YM.
