6．how　考查宾语从句的连接词。设空处引导宾语从句，作explains的宾语。分析句子结构可知，句中缺少状语，表"方式"，故用how连接该从句。

　　7．Using　考查非谓语动词。句中已有谓语can control，因此，设空处应用非谓语动词；use与其逻辑主语he or she之间为主动关系，且非谓语动词在句中作方式状语。故填Using。

　　8．to/with　考查介词。be linked to/with ... 为固定搭配，"与......连接"。故填to/with。

　　9．equipped　考查动词的语态。be equipped with ... 为固定搭配，"装配有......"。故填equipped。

　　10．easier　考查形容词的比较级。设空处在定语从句中作宾语补足语，而且本句暗含比较意义，应用形容词的比较级。故填easier。

　　难项分析：

第四处：that→what　考查宾语从句。分析该句结构可知，该句为含有宾语从句的主从复合句，what既作宾语从句的引导词，也作从句中及物动词thought的宾语，而that在宾语从句中不作成分，故将that改为what。
