Do you have any idea it takes to successfully reach the top of Mount Everest?| A．whether | B．how | C．which | D．what |

答案
| D |
解析
试题分析：考查同位语从句的连接词。本题的同位语从句what it takes to successfully reach the top of Mount Everest作为名词idea的同位语。该从句中的take后面缺少宾语，故使用连接代词what。Whether属于连接词，在句中不充当任何成分。How属于连接副词，在句中做状语。Which指特定范围之内的某一个。故D正确。
点评：在名词性从句中Whether属于连接词，在句中不充当任何成分。How属于连接副词，在句中做状语。Which指特定范围之内的某一个。What是连接代词可以在句中知道主语，宾语，表语等。 |
