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，）
