25.—Does your sister enjoy the new camera？

—Yes.______，the more skilled she becomes.（  ）

A.As she takes some pictures

B.The pictures she takes more

C.As more pictures she takes

D.The more pictures she takes

25.D【解析】由“the more skilled she become”的倒装结构可以看出，本题考查“the more…the more…”句型。故D选项正确。

26.Kate is so ______ that she cried for days when her pet dog die

D.（  ）

A.sensible

B.sensitive

C.straightforward

D.suspicious

26.B【解析】sensible“明智的，通情达理的”；sensitive“敏感的，易受影响的”；straightforward“简单的，坦率的”；suspicious“可疑的，多疑的”。句意：凯特是个敏感的女孩，小狗死后她哭了好几天。故选B。

27.—What were you doing when Lucy phoned you？

—I had just finished my work and ______ to read a book.（  ）

A.starting

B.start

C.was starting

D.have started

27.C【解析】四个选项均有“开始”的意义，而上句Lucy phoned表示的是过去某个瞬间发生的动作，要用过去进行时，由此得知句意应为“我刚写完作业，正要开始读书”。因此选C。
