宾格
(1) 宾格代词分别是：
第一人称：me, us（复数）
第二人称：you（单复同）
第三人称：him, her, it, them（复数）
例如：No one can jump over the channel except Mary and him (这里用宾格，而不能用he)
(2) 宾格代词在句中作动词或介词的宾语，改错题中常误用主格代词作宾语，应改为宾格
例如：I go out with her. (注意介词 with)
Most of us came from village. (注意介词of后面必须用宾格)
例题：
(1)
The texture of soil is determined by the size of the grains or particles that make up.
应改为：make it up
解释：make up是及物动词词组, 需要宾语, 依句意加上宾格代词it, 指代soil
(2)
Quails typically have short rounded wings that enable ---- spring into full flight instantly when disturbed in their hiding places.
(A) they
(B) to their
(C) its
(D) them to
答案：D
解释：空格处需要及物动词enable的宾语, A是主格代词, 不能作宾语; B、C中的物主代词不能接动词spring; D中的them是宾格代词作宾语, 同时to与spring构成不定式, 作复合宾语
