Question

never can i understand why those people lie to their children 这句有错误么 thank you

Answer 1

没有错误.
never 放句首时,句子要倒装. why引导宾从作understand的宾语.
句意: 我永远不会明白为什么那些人要对他们的孩子撒谎.

追问

弱弱的再问一下 how close parents are to their children has a strong influence on the character of the children。这里的has 作什么成分 为什么不用having做伴随状语。非常的thank you

追答

这里的has 是谓动,当然不能用having.
how close parents are to their children 是主从作主语.
has a strong influence on 是一个短语,"对...产生强烈的影响"
句意: 父母与子女的亲密程度对孩子的性格产生强烈的影响.

Answer 2

部分倒装，没有问题。
