题目:The keynote speaker maintained that there is a critical period
for lauguage learning,
after which nativelike attainment is extremely difficult,
if not impossible.
补教老师翻译:发表重要谈话的演说者认为说，语言学习有一阵痛期，
克服之后依然在类似母语般的熟悉运用上，仍有困难
疑问:中文念法是先念if not impossible,
再念after which nativelike attainment is extremely difficult吗?
请高手帮忙教学一下 要先念哪一句 不然念起来都很绕口 谢谢
给100p给高手帮忙 谢谢
