To prevent cybercrime more effectively ,it is important to make new laws and creat international standards for them similar to ( ) concerning international airspace . A. that B.what C. one D.those 请老师逐个讲解，谢谢！

解题思路： 如下
解题过程：
选D。
此题考查代词的用法。此处 those 代替 laws，concerning international airspace 为其后置定语。
that， one， those均可用来替代前面的名词，以避免重复，其用法如下：
一、that替代"the+单数名词（可数或不可数）"，表示特指，that指前面提到的"同类"事物。如：
Few pleasures can equal ________ of a cool drink on a hot day. （全国卷）
A. some B. any C. that D. those
「分析」答案选C.that替代the pleasure，指与前面提到的同属"快乐的事".
二、one替代"a＋单数可数名词"，表示泛指。特指的the one相当于that；the one复数形式the ones，在口语中也常用those代替；当后面有of短语时，一般用that或those，当有前置修饰语时，只能用one（s），如the red one.one（s）， the one（s）， those， that都是替代"同类"事物，其中只有that可替代不可数名词。如：
1. We needed a new cupboard for the kitchen. So Peter made ________ from some wood we had. （广西卷）
A. it B. one C. himself D. another
「分析」答案选B.one替代"a cupboard".
2. Meeting my uncle after all these years was an unforgettable moment， ________ I will always treasure. （全国卷）
A. that B. one C. it D. what
「分析」答案选B.one替代"a moment"，作an unforgettable moment的同位语。后面接的是它的定语从句。又如Cook was a strict but good captain，one who took good care of the sailors on his ship.
3. -Why don't we take a little break？
-Didn't we just have ________ ？ （全国卷）
A. it B. that C. one D. this
「分析」答案选C.one替代a break.
4. Mr Zhang gave the textbooks to all the pupils except ________ who had already taken them. （全国卷）
A. the ones B. ones C. some D. the others
「分析」答案选A.后面的定语从句是特指，the ones替代the pupils.此处也可用those.
最终答案：略
