esson 18-1 Porpoises
There has long been a superstition among mariners that porpoises will save drowning men by pushing them to the surface, or protect them from sharks by surrounding them in defensive formation. Marine Studio biologists have pointed out that, however intelligent they may be, it is probably a mistake to credit dolphins with any motive of lifesaving. On the occasions when they have pushed to shore an unconscious human being they have much more likely done it out of curiosity or for sport, as in riding the bow waves of a ship. In 1928 some porpoises were photographed working like beavers to push ashore a waterlogged mattress. If, as has been reported, they have protected humans from sharks, it may have been because curiosity attracted them and because the scent of a possible meal attracted the sharks.

練習(xí)感悟：
今天是課文前半部分零截，生詞多溯壶，語(yǔ)法現(xiàn)象也多领突。感覺(jué)最近的文章讀起來(lái)都比較費(fèi)力，句子中代詞的指代關(guān)系比較難，各種從句混在一起，或者嵌套經(jīng)常分不清。
