中学英语—语法 名词所有格!
发布时间:2010-09-02       
 名词有三个格:主格、宾格和所属格。这里我们只讲属格,属格表示所有关系,它有两种不同的形式。

  一、一是在名词尾加's

  (如 my brother's toy我弟弟的玩具,the hostes's living room女主人的起居室),如果原名词已经有复数词尾s,或es,只加' (如:soldiers' training ground士兵的训练场,teachers' readingeoom教师阅览室)。注意,如果名词虽然是复数,但不是以s结尾,则仍加's (the children's mother孩子的妈妈)

  1) It is widely believed that the pull of gravity on a falling raindrop changes  round shape into a teardrop shape.

  [A] of the drop [B] the drop's [C] drop of [D] drops their

  2) The winner [A] photograph was of [B] an old barn(仓库) window covered with [C] a [D] delicate, lacy frost(带花边的霜).

  二、另外一种属格是由介词of加名词构成名词短语

  3) At [A] birth, the [B] head of a bady is extremely large in [C] relation to a [D] rest of the body.

  三、例题解析

  1) B为正确答案。"It"是形式主语。"that…"引导的是主从句。主从句的谓语是"changes…into…""把……变成……"。其中"…into…"的前后应是对应的平行结构。很明显A和D都不行,不能把"changes"误作名词。C改变了"…into…"的平行关系。只有B既能与前边的动词"changes"衔接,又能保持"…into…"的平行关系。

  2) A错。 改为winner's。

  3) D错。 改为the。 名词有三个格:主格、宾格和所属格。这里我们只讲属格,属格表示所有关系,它有两种不同的形式。
