1．t feed 考查动词不定式。根据语境可知，此处应用不定式表示目的，故填t feed。
2．Having 考查非谓语动词。根据语境可知，句子主语adult blue whales与动词have之间构成逻辑上的主谓关系，故填have的现在分词形式。

Ⅱ.阅读理解
As far back as the age f dinsaurs millins f years ag, turtles wandered arund the Earth. Even nwadays it is generally assumed that turtles are the wrld's steadiest creature.
Hwever, a new research shws 61 percent f the 356 species f turtles are already threatened r n lnger exist. The destructin f their hmes, disease, climate change and ther reasns have caused their ppulatin t drp sharply. In a new study published in the jurnal BiScience, a team f scientists frm varius institutins claim that turtles are ne f the mst threatened amng the majr vertebrate (脊椎动物) grups.
This culd, the authrs say, have serius cnsequences fr the eclgy. Turtles cntribute t the health f many envirnments, including desert, wetland, freshwater and marine ecsystems, and the decline may lead t bad effects n ther species, including humans, they explain. Whit Gibbns, senir authr and prfessr at the University f Gergia's Savannah River Eclgy Labratry, says in a statement that the intentin f the study is t infrm peple abut the vital eclgical rles f turtles.
One f the imprtant qualities f turtles is hw diverse they are when it cmes t fd. This allws them t have a majr impact n fd webs f their hmes all ver the wrld. In sme areas, the density (密度) f the turtle ppulatin makes them an imprtant part f the ecsystem. With their gathering, ther species that feed n them and their eggs are sure t have a large pl f fd.
Fr plants, turtles are als extremely imprtant as they distribute the seeds f many plant species. When they eat, sme seeds are nt destryed by the digestive prcess and instead make their way ut f the animals' bdy. Sme turtles are the main dispersal (传播) agents f certain plants and their seeds.
These are nly a few yet very vital rles that turtles play in the eclgical landscape. Unfrtunately, many species are in serius decline and in danger f disappearing cmpletely.
