麻烦看看这题 one that

您好我们都知道one和that（those）都可以用于比较,期中those指代复数可数名词至于具体的区别就是
1如果比较的对象是被定冠词（the）修饰还是不定冠词（a an）修饰,
比较的对象是被定冠词（the）修饰时,如果是单数名词我们就用that,复数则用those
The boy with a pen in one of his hands is much taller than that in the red（那个手里拿着笔的男孩比那个穿着红色衣服的男孩高多了）
The people in China are generally not as rich as those in the USA .（中国人总体上没美国人富裕.）
2如果比较的对象被不定冠词修饰时,我们要用one
如 A desk of wood is not so light as one of glass.木质桌子比玻璃桌子要重
希望能帮到您
