你好!我是英语师范学校毕业的,希望可以帮助到你哦!
首先,你需要理解这句话的意思.
这句话是说:只有在他在“说”上面习得相当多的能力后他才开始学习读与写.
这句话的考点是only放在句首要用倒装的用法.
only引导的从句是一句条件状语从句.这句话的“条件”是“has acquired considerable facility in speaking ”,注意,其中用的是现在完成时,那么,后面满足了这一“条件”后的“结果”就要用一般将来时表将来,所以要用will he begin.
这句话不是强调句,你混淆了强调句与倒装句了.
强调句的公式是:
It is +n./np(noun phrase) that /who +do sth.
that/who 前面的内容为整句话的强调成分.

只有B的时态是对的
Only after表示“要是怎么怎么就……”有假如的意思
这个事情并没有真正发生,所以不能用过去

因为主句用的是HAS 说明是现在完成时,意思就是只有当他。。他才会开始。 所以从句应该用将来时。 选C的话应该用 DOES,因为动作还没发生。

只有在他得到了说的技巧,他才会学习去写和读,
选B是因为这很明显还没有得到说的技巧,读写技巧也要以后再学啊,所以用将来时
