Nearly all animals are influenced by sun cycles and have developed a biological clock in their bodies following these cycles. The moon also exerts its force and influence on the sea. Its gravitational attraction causes the rising of the tide. ___2___. When the moon is behind the Earth， centrifugal force causes the second tide of the day.
Animals living in tidal areas must have the instinct of predicting these changes， to avoid being stranded and dying of dehydration. Since the time of the dinosaurs， the king crab has been laying eggs at the seaside in a set way. To avoid predator fish， the eggs are always far from seawater and protected by sand. In the following two months， the eggs undergo dramatic changes related to the cycles of the moon. When the second spring tide comes， the young king crabs have matured. ___3___.

解題思路：
1.讀文章標題，了解文章主題(提示： 如果被選項偏離文章主題，則該被選項成為答案的可能性較小)
2.仔細讀被選項，體會被選項之間在語意， 在用詞， 在結構上的相互關系(答案往往出自有關系的被選項中)
3.找出被選項中的典型篇章詞匯(人稱代詞， 指示代詞， 定冠詞結構)---判斷答案選項的關鍵；
4.如果被選項中出現了“we(us， our， ours)”或“you(your， yours)”這樣的人稱代詞， 這樣的詞匯在上下文的使用中應該是一致的。
5.如果被選項出現時態差異， 則時態是一個重要的解題線索 (提示： 相鄰語句使用的時態一致(基調時態)： 同為現在時態或同為過去時態； 但是， 如果一個句中帶有自己的時間狀語，則其可以使用自己獨特的時態，而不受所在句群的基調時態的影響)
6. 空格前句如果是觀點句，則空格處常常出現用于解釋論證的例子或解釋性的話語； 空格前句如果是概括句(講述一種通常的情況， 往往出現some， most， a few， generally， usually等詞語 )， 則空格處可能會出現轉折句， 或出現解釋性的話語.
7. 最長句， 轉折句常常是答案。
