Last evening,my mother is boiling some fish soup in the kitchen while our dog,Lucky,was standing there.It would spend some time before it was ready.Mum decided to have rest in the bedroom.Soon she was asleep .Lately Luckycame in and woke her up.Mum thought it just looked forward to go out for a walk and was totake it out,but when they reached at the stairs .Lucky Wouldn't go any far and barked towards the kitchen.Suddenly Mum realized why the soup was sitll being boiled.She hurried there and found there was little soup lesaving in the pot.Mum quickly turned on the gas.
英语共十处错误..
化学：由正负离子数相等 则 2X2=6Xn(Al2(SO4)3) + 2Xn(ZnSO4) 同时 n(Al2(SO4)3):n(ZnSO4)=1:3 计算出硫酸锌的物质的量为1mol 则硫酸锌的质量为161.45g
