Spontaneous communication and free interaction are possible in any language only when teachers and their students have built up a warm, uninhibited, confident sympathetic relationship and when such a relationship also exists among the students themselves. In the first lessons no such state of affairs exists as yet. The teacher's efforts from the beginning should be devoted to building up such relationships through enjoyable, successful experiences in using interesting and amusing segments of language in a multiplicity of ways.

单选题Your vessel was damaged and initially assumed a significant list and trim; however，further increase has been slow. Based on this data，what should you expect?（）AThe slowing is only temporary and the vessel will probably suddenly capsize or plunge from loss of stability due to change in the waterplane areaBThe vessel can probably be saved if further flooding can be stoppedCThe vessel will continue to slowly list and/or trim due to the free surface effect and free communication effectDThe vessel will suddenly flop to the same or greater angle of list on the other side and may capsize
