英语作文语法错误求检查,
Nowadays,we are exposed to many advertisements in the streets during each summer holidays.To study this social phenomenon carefully,last week,I carried out a survey which is about whether they will arrange extra lessons for their children among300 parents of primary and junior school students.The survey implies thatmore people are sending their kids to the remedial classes than was thought.The writing,music,painting,dancing and some compulsory courses in the school are the hit.The students are expected to grow an interest about some extratalent and skill,and not to fall so far behind others.
小弟语法水平实在是渣,
五句话而已QAQ高中水平的不难的啊QAQ求个大神救命啊——
