帮我做下这道英语题目

选C
B 用whose就不能用the，把所指的名词带入原句就是some trees 's the leaves有了some，又有the那就茅盾了．名词所有格不能和the 连用。
D the leaves were black 有主语又有宾语，所以不能用that
把A和D所指名词代到原句中some leaves of the leaves were black
some trees in the leaves were black
树不可能在叶子里对吧！

c of which

which 是指带 trees

of 是因为，leaves 从属余 trees ，是树的叶子。用of

翻译是：我看到了一些树，它们的叶子都发黑了

A in which对的
B whose后面不能跟the
c of which 不对，因为叶子再树上应该用in
D that在从句中要参加成分

c
in which 树里面错误
whose 就不用the
that 接从句不妥

选C。
主要是因为“the leaves of the trees",而不是"the leaves in the trees".因为树叶是树上长出来的，而不是人工加工的。whose 主要表示“谁的”，如果这边要用whose的话，那么就应该是 i saw some trees whose leaves were black,就不要the 了。

选C
树的叶子,用of
