We are here to make available to you,as best we can,that expertise.这里的that是引导什么从句？

We are here to make available to you,as best we can,that expertise.这里的that是引导什么从句？

将原句中as best we can “尽我们所能”的插入语先去掉
句子应该可以这么写We are here to make that expertise available to you.
如果that是引导从句的话，make后应该是宾语从句，但是如果引导宾语从句的话，后面从句expertise available to you.缺少谓语，所以这里that应该不引导从句
翻译：在这里我们将尽我们所能让你了解（接触、获得）那些专业知识。

这个that是指示代词，expertise 名词。that expertise那些专业知识。追答that expertise 作make的宾语。本应该是：make that expertise available to you...整句汉义：我们在这儿尽我们最大努力使你获得那些专业技能（知识）。
