Many people think of sharks as dangerous monsters.But human beings cause a far greater danger to them than they do to us.Although shark attacks do occur，they are quite rare.According to one estimate，however，humans kill 100 million sharks every year.（1）GG
Why should we save the sharks？
Sharks take up the top position on the food chain in the ocean.As sharks die off，the population of the animals that sharks consume will increase.This，in turn，means that the number of the creatures those animals eat will drop.（2）FF Fish that eat algae（藻類）are also included.This can cause algae to spread so much that it damages coral reefs.
（3）DD The ocean not only produces more oxygen than all the rainforests on Earth combined，but also removes half of the man-made greenhouse gas from the atmosphere.Once sharks die off，the global ecosystem will be upset，affecting all creatures including human beings.
Don't use shark products
First，vitamin energy drinks and leather goods can be made from shark parts.（4）BB In addition，shark meat is sold around the world，sometimes under misleading names such as rock salmon or white fish.
Shark fin soup is a popular dish.However，the process of getting fins is cruel.Fishermen cut the shark's fins off and then throw the shark back into the water，still alive.（5）CC Sharks breathe by swimming，so ? shark that can't swim will die.
A.It is time for children to learn about sharks.
B.Shark oil is also used in many popular beauty products.
C.Then the shark dies slowly，sometimes over several days.
D.Actually，the killing of sharks will affect the whole planet.
E.People in some countries are especially keen on shark products.
F.Among them are some sea fish that humans consume every day.
G.This number is a warning that many kinds of sharks may die out.

2．Walk Out of the Comfort Zone and Try New Things For most high school students，free periods （課、節(jié)） are useless.From what I have seen，few do homework. （1）
.This makes it impossible for those who actually want to do work to complete any.As a senior next year，I think extra periods should be used to take optional subjects.
（2）.Now is the time for us students to choose a suitable one.We will experiment in different fields of study.We will never know if we are interested or talented in a subject if we don't try it.
In my 8th grade，I was told that I had to take an art class as a graduation requirement；so in the 9th grade I took Studio and Art.One of the projects was to build a clay pot，but I built mine incorrectly，so it broke in the kiln （窯）. （3）.Now I know for sure that I do not want to be an artist.However，the class was one of my favorites that year.I was able to try new activities and test my ability.
