One possible version：

Dear Li Hua,

I feel greatly honored to be trusted with your personal affairs．

I have to say that you are not alone when having trouble communicating with your parents．Almost everybody has it or had it when they were in their adolescence．Therefore, it’s a common problem shared by many, whose cause lies in what we call “generation gap”．

As for my advice for you, first, don’t hide your feelings．You can make it a routine to share your thoughts with your parents．Second, convince them you have tried your best．It is not their fault to place high expectations on their child．I believe they will be satisfied with you as long as they know you have tried whatever you can to live up to their standard．

Anyway, there is no one who love you more than your parents in the world．Whatever you are, they will always be there for you．Love them, and love can heal everything．

Yours sincerely,

Brad

ab是长为l的均匀带电细杆，P1、P2是位于ab所在直线上的两点，位置如图所示。ab上电荷产生的静电场在P1处的场强大小为E1，在P2处的场强大小为E2。则以下说法正确的是

A 两处的电场方向相同，E1＞E2 B 两处的电场方向相反，E1＞E2

C 两处的电场方向相同，E1＜E2 D 两处的电场方向相反，E1＜E2

D解析假设杆带正电，可将杆看成由无数个小带电体并排组成，由电场的叠加原理可知，P1处的场向左，P2处的场向右，两处的电场方向相反；又由对称性，P1左侧电荷产生的电场要与右侧对称地抵消一部分，因此E1<E2 ，所以D正确
