The ocean is home to tens of thousands of fish． You can see fish swimming freely in the water． But you may not know that fish cannot explore every part of the ocean．

Recent studies have found that the deepest depth（深度）a fish can swim is 8，200 meters．（1）　　This is because of a chemical（化学物质）in fishes' cells（细胞）that is called Trimethylamine N﹣oxide（TMAO）．

For example，if you take a ping﹣pong bal 10 meters underwater，the pressure turns it into a tiny piece of plastic．（2）　　TMAO warns fish of this danger at about 8，200 meters． If fish swim deeper，the TMAO chemical stops working and starts to damage（破坏）the fishes' brain cells．

Although there is life at the bottom of the sea，most fish live within （在……范围内）the top 1，000 meters of the ocean．（3）　　

（4）　　The anglerfish is one such fish． It lives about 2，000 meters deep in the ocean． There is no sunlight at this depth．（5）　　They use the light to find food． Below even these fish is the cusk﹣eel． These small fish live close to the ocean floor at a depth of 8，000 meters，far out of reach of hungry predators（猎食者）．

A． But anglerfish can produce light themselves．

B． This is about three quarters of the depth of the deepest part of the ocean．

C． Deeper down in the ocean，the most dangerous animals are the deep﹣sea fish．

D． Most things break down after a certain depth underwater because of the high pressure．

E． Even sharks，the "kings of the ocean"，have never swum deeper than 4，000 meters．

If you，like me，were born in the Year of the Pig，then you are （3）　　，thoughtful and loyal（忠诚的）．The Year of the Pig is filled with good wealth．

Now，let's（4）　　a closer look at this interesting animal． Pigs were first kept by man about 9，000 years ago，and are still a very common （5）　　animal in many parts of the world． We don't just use pigs for their meat﹣almost every part of the animal is used． The hair is used for artists brushes． The fat is used （6）　　floor wax（蜡），rubber（橡胶）and plastics．

Pigs have also been important in the world of entertainment． In 1995 the film Babe starred（使主演）a loveable talking pig as its main character． The film （7）　　an Oscar Award． In England you can even go to watch pig racing． A farmer，Rob Shepherd，has been raising money （8）　　charity by holding pig races on his farm．（9）　　seems that people don't just want to eat pigs！

Pigs also play an important role in the English language． For example，if someone says that he （10）　　to the sun one day，you can say "Pigs might fly！"to him． Hungry？Well then，you can say "pig out" and eat lots of food．
