我写的英语作文请帮我看下有没有语法错误请帮忙改正谢谢

1 in our dormitory maybe have some controversy，有语法错误，把in去掉，把maybe改为may
2 we can have a good rest and put our heart into study个人认为把put in to 改为concentrate one,mind on比较好 还是尽量不用heartS吧 3 I beliveve it is high time that we took some effective measures to solve this problem.在下认为这句用的很漂亮！！！4 A bright future is waiting for us when all the measures are taken seriously implementation.似乎后面应改为taken into serious implemention
