俺都打算戒网了，又被你这问题拽出来了。

不是什么大事，你家LD可能平时写的多，说的少点。

俺上星期俺们公司的口语老师 evaluated my oral English. She gave me five (0-5 scale) on fluency. 听着还不差。可她说，俺一会儿kid，一会儿kids.到底俺有几个孩呀，俺就一个宝贝儿子。说高了，俺也经常 tongue slips. 幸好俺没把hu*****and说成hu*****ands.否则，俺可能这会儿得在监狱上美坛了.
俺汗一个.

Practising English with your LD in daily life. Whoever makes such low-level mistakes will cook the dinner and do the dishes. That will help. :)
