As is graphically depicted in the cartoon, a young girl is talking with her mother. She says ironically, “Good news mom! I was accepted to the college of your choice!” Then, her mother smilesand seems content with this result. Apparently, the cartoon aims toreveal the fact that a majority of modern parents play anincreasingly negative role in their children’s growth.
There are several possible reasons accountable for thisphenomenon(中心句). To begin with, family in growing numbers has onlyone child; therefore, parents oftentimes focus all their attentionson that child and exert much pressure on him or her(原因一). Moreover,numerous parents intend to realize their unfulfilled dreams byletting their children learn what they failed to learn and applyfor the college by which they failed to be accepted, because theyhave become richer and they believe that they have the power tomake what they wanted and want come true now(原因二). For instance, myuncle used to be a poor man and his dream that one day he wouldbecome a violinist was broken because of lack of money. But he madea fortune by selling coals, and then forced his son, my youngerbrother to practice playing violin. My brother was a huge fan ofsports, but now he has to play violin everyday unwillingly andofter quarrels with theirparents(举例：原来-然后-结局).
To sum up, it is unreasonable for parents to control theirchildren’s life(总结句). In order to help them grow happily andhealthily, parents are supposed to communicate with their kidsabout what they are really interested in(建议一，目的句型). Meanwhile, itis about time that parents let their kids make their ownchoices(建议二，“是时候”句型). Only in these ways will children grow in apsychologically happy environment and realize their owndreams.
