几道英语关于代词的语法题目.
还有请尽量保持正确度啊。
因为真的不是很懂所以才问的，请稍为详细一点哈～
1.Scientists have given a warning to reduce the amount of lead in paint especially ( ) used on children's toys and furniture.
A.that B which is C.it is D.one
我的解题：我选择了B，因为认为lead作为主语然后应该是被动语态的。
所以是be used。
2.In Betty's eyes,her teacher was just her best friend,most trusted person or ( ) she would turn to in time of trouble.
A.when B.whom C.one D.who
我的解题：我选了B，因为觉得这里的代词应该是指代寻求帮助的人（宾语）
正确答案是C
3.I’d like something to read during the journey,and (anything) will do.
我的解题：根本就没有读懂句意。
4.A good book is (one ) which benefits readers.
我的解题：我用的是somthing，和one有什么区别（这题请详细回答和分辨，）

看来楼主没有弄清one和that作为代词的用法,
one用来代指上文提到的可数名词单数,泛指上下文提及的同类事物中的一个,属于同一类而不是同一个事物.
that 用来代指上文提到的不可数名词和可数名词单数,可数名词复数的情况要用those.
第一题,需要指代的是不可数名词lead铅,所不能用one,只能用that.which is 可引导定语从句,但前面缺少先行词.
第二题,同解,whom作为关系代词可引导定语从句,并在从句中充当宾语,但其前面应有名词作为先行词,问题：缺先行词
第三题,我想要些东西在旅途中阅读,任何东西都可以 ,表达任何事物,用anything
第四题,因为a book 是可数名词复数,所以在文中应用one来指代,且something 是不定代词,不定代词作先行词,关系代词只能用that.

1;that表代词相当于同位语which is表示非限制定语从句，used用被动做修饰语修饰that
2one作为表语与person‘，friend并列。whom是who的宾语连接句子
3在旅行中我想要些东西读读，和一些愿意做的事情
4something的引导词用that

额 题呢？

1. Scientists have given a warning to reduce the amount of lead in paint, especially used on children's toys and furniture.
你的认为是对的，lead主语是被使用，所以这里不用that，直接用过去分词used 引导定语。

2. In Betty...

1. Scientists have given a warning to reduce the amount of lead in paint, especially used on children's toys and furniture.
你的认为是对的，lead主语是被使用，所以这里不用that，直接用过去分词used 引导定语。

2. In Betty's eyes, her teacher was just her best friend, most trusted person or (one) she would turn to in time of trouble.
你是想用whom引导定语从句吧，可定语从句的先行词呢？her teacher 为主语，was谓语，后面her best friend, most trusted person or one she would turn to in time of trouble.都是宾语，one引导的同位语从句作宾语。

3.I‘d like something to read during the journey, and (anything) will do.
翻译：旅途中我想找点什么书来看，可惜没有找到。

4. A good book is (one ) which benefits readers.
翻译：一本好书应该能使读者受益。你是理解which引导的定语从句的，这里明显是受到前面选择题something的影响，前面主语就是book，后面one指代book，哪里还能其他something啊？
