在严谨的数学计算中,我们都认定1+1等于2,这是定理。然而,在实际生活中,我们又常常会发现:1+1并不一定等于2。比如,一条小溪加一条小溪,就不再是两条小溪,它们汇成了一条小河;一堆沙子加一堆沙子,就不再是两堆沙子,它们聚成了一座小塔。我们的语文教学中,也会有这样的现象……这是一堂口语交际课,安排的内容是“即兴演讲”。我给学生列出了8个即兴演讲的话题, In rigorous mathematical calculations, we all agree that 1 + 1 equals 2, which is the theorem. However, in real life, we often find that 1 + 1 is not necessarily equal to 2. For example, a stream with a stream, no longer two streams, they merged into a stream; a pile of sand and a pile of sand, it is no longer two piles of sand, they gather into a small tower. There is also such a phenomenon in our Chinese teaching ... This is a colloquial communication class, arranged for “impromptu speech”. I gave the students a list of eight impromptu speeches,
