今天一鼓作氣來它兩篇。

1.Some of the senses that we and other terrestrial mammals take for granted are either reduced or absent in cetaceans or fail to function well in water.

【又選自文章的首句！是由either..or..or 連接的句子。be reduced,be absent ,fail to function寫了海洋動物鯨在水里各項器官的一個狀態(tài)-degenerate退化。terrestrial mammals 陸地哺乳動物，take for granted 當成理所當然。造句：some education facilities in our school we take for granted are lacking in Africa.】

2.It has been speculated that,as the blowholes evolved and migrated to the top of the head ,the neural pathways serving sense of smell may have been nearly all sacrificed.

【it 做形式主語的典型句式，類似開頭的有：It's bee said that~；speculate預測；evolve 進化；migrate移動；neural pathways 神經(jīng)系統(tǒng)；sense of smell /taste/touch/vision/hearing嗅覺/味覺/觸覺/視覺/聽覺；be sacrificed 犧牲】

3.This contact may help to maintain order within a group,and stroking or touching are part of the courtship ritual in most species.

【stroke 表示撫摸和touch同意思。courtship ritual表示求偶行為，原來鯨是通過觸覺求偶，長見識了?！?/p>

4.Such variation can no doubt be explained with reference to the habitats in which individual species have developed.

【variation表示變異，with reference to 關于，依據(jù)。habitat棲息地?！?/p>

5.Such weaknesses are more than compensated for by cetaceans well-developed acoustic sense.

【more than 多于，acoustic聽覺的，相當于hearing sense，因為compensate 理解的不到位，整句話表意不明白?！?/p>
