Many people,especially who work in office every day,liketo go to have fast food ortakeaway food near their workplace.Thefood they eat every day is full of oil and fat,it makes them fat.Most seriously,the cycling of their blood will slow down.It makes them ill when they are old.
What should a healthy person eat every day?well,I will introduce my "Healthy eating habit" Itcomes from doctors,and it is believable.
While people do alot of work,the energy intheir body are burning,too.So you need noodles,rice,milk,bread and eggs.Ifyou don'teat them,you will faint.Fruit and vegetables arenecessary,too.
They are a lot of vitamins.It makes you not sick easiy Vegetables help the other food easier to be digested.Andthey can give you water.

Everybody knows smoking is bad for health.Those who smoke too much may not live long.Smoking may cause many diseases.The most serious one is lung cancer.Smoking can also do harm to those who don't smoke,If all smokers give up smoking,we can enjoy clearer air.
5.My hobby
I like playing basketball .It鈥檚 very interesting .I often play it with my friends.It鈥檚 a team work.Everyone needs to work together with others.I can also make many new friends in the game.My favorite basketball player is Yao Ming.He is very tall and plays basketball very well.I want to play in NBA one day like him.
6.The Present My Father Gave Me
When I was young,my father ,who always taught me how to be a true man,told me that it is essential to be tolerant in your life whatever happens.
And that remains the most valuable present he gave me,I think To be tolerant,I need to keep calm when great trouble lies in front of me,however difficult it is to overcome it; To be tolerant ,I need to resist the temptation of all kinds of the outside world,even if it is so attractive; To be torlerant,I need to pull myself(鎺у埗鑷?繁鎯呯华) in times of extreme sorrows and joys,no matter how they affect me.
7.A Tree
A tree has three main parts,the roots,the branches and the leaves.Under the ground,the roots spread out so that the tree can stand firm.Above the ground,the roots form the trunk,and the trunk supports the branches.Near the top of the tree,the trunk pides into branches.At the top of the tree,the leaves grow out of the branches.The leaves receive sunlight to help the whole tree grow.
8.The Man I Respect Most
My father is the man I respect most.Stern as he may be,he never fails to show his care and consideration.Once I broke a neighbor's window.Seeing nobody around,I ran away immediately.When Dad came home,he noticed my uneasiness and asked me what had happened.
I could only tell him the truth.Rather than scold me,he praised my honesty and then encouraged me to apologize to our neighbor.I learned from this episode that not only does Dad take care of our health but he also teaches us how to be good citizens.How lucky I am to have such a good father!
9.My Favorite Food
There are many many foods we can eat,such as apple,banana,pear,carrot,onion,orange,potato and many others.My father likes to eat very thing,expect it is not be able to eat.My mother likes to eat vegetables and fruits,she usually eat some meat.I like to eat meat,and fruits,too,but I do not like to eat vegetables,and apple is favorite food.
It is very tasty and has many things,which our body need; they also can clean our teeth.Some of them are red,some of them are green.I like to eat the red ones,because they look nicer than the green ones.Apples are very useful,someone say apple can make people more beautiful and strong.I do not think apples can make us more beautiful and strong,but I believe someone who always eats apples will be more health than someone who does not like to eat apples will not be very strong!
10.
Elephant
Elephants are like us in some ways.They live for a long time -- fifty or sixty years.They can remember things very well.They never forget sadness or great happiness for many months.
Elephants are like us,but they are also different.
They live in families:families of females.There will be a few young males--a few baby boys.But the females will soon send them away.An elephant family keeps only its daughters,mothers,grand-mothers and its great-grandmothers.They stay together for fifty,sixty..,a hundred years.The older animals look after the young ones.The mothers teach their daughters and set a good example.And what happens to male elephants?Well,the young males stay with their mothers for a time.Then they must leave the family.The females just send them away.A bull elephant doesn't often have a friend.He lives apart,away from the family,and often away from other bulls.
Sometimes the females call a bull.He can visit them then,and stay for a time.But soon his "wives" and sisters send him away again.The females have a very happy familly life.What do the bulls think about it?We don't know.
