My father is of middle height.His eyes are sharp and full of expression.He always appears serious and looks like a judge.At first sight you may think he is hard to come near.In fact he is very kind and thoughtful① of others and their feelings.Appearance often makes people think wrongly; therefore we cannot give an opinion about a person by appearance.
My father is a man of success.By his own talents and efforts,he has achieved great achievements in what he does.He has not only created wealth for society but also provided our family with a rich life.Now he is well-known to people all over the city.People of all walks of life②come to my house and,as a result,I gain lots of hard-earned social experiences③and see more joys and sorrows of the world.
At home my father is a severe parent.He is very strict with my mother and me.He does not allow my mother to accept anything from others.He requires that my mother should go to office in time and leave it last.He has high expectations of me.④ When I am lazy and idling away my time⑤,I can see that it hurts him deeply.When I am doing something great,such as carrying out an experiment,he is more than excited.With such a father I am always reminded of going on and on,never giving up.
1、口算。
指名口算练习十一第6题。
2、揭示课题。
这节课,我们复习小数的性质和数的改写。(板书课题通过复习,要进一步认识小数的基本性质和小数点移动引起小数大小变化的规律,能比较熟练地进行数的改写。
