Is the whale the world's largest fish? No．It looks like a fish, but it is really a mammal(哺乳动物)．Then what's the world's largest fish? It's the whale shark．
Although the whale shark is our biggest fish and lives in many oceans around the world, few people have ever heard of it．Scientists have not been studying whale sharks for very long．Much more needs to be learned about them．
A whale shark is sometimes called a “gentle giant(温柔的巨人)”．It likes to be alone and doesn't care a bit about divers or humans．The biggest whale shark weighed 24,250 pounds and was nearly 40 feet long．This makes it heavier and longer than a school bus．
Inside its huge mouth are great numbers of very small teeth．To count all of them, you'll need to do some math．The whale shark's teeth are arranged in rows．There are between eleven and thirteen rows on each jaw(颚)and around three hundred teeth in each row．
However, the whale shark hardly uses its teeth．It does not chew or bite its food．Large amounts of water are pulled into its mouth and then pushed out through its gills(鳃)．
For a few months every year, a group of whale sharks comes to Ningaloo Reef, off Western Australia．This gives scientists a wonderful chance to study the large fish．Whale sharks do live in other oceans of the world, but no one knows their population．It is possible that our biggest fish may need protecting．It is one of the reasons why scientists continue to learn all they can about these gentle giants．

阅读理解
You will have a lot of reading to do in this grade this year．You can do more of it in less time if you learn to read rapidly．
Perhaps you have been told about some habits (习惯) which keep a person from reading fast and have been strongly asked to break those habits which you might have．
Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions．
(1) Do you move your lips (嘴唇) when reading silently?
(2) Do you point to words with your finger as you read?
(3)Do you move your head from side to side as you read?
(4)Do you read one word at a time?
If you answer“yes”to any of these questions,start at once to break the habit．If you move your tips，hold your fingers over them，or hold a piece of paper be-tween your lips while you are reading．Then if your lips move，your will know it and can stop them．
If you point to words，hold the two sides of your book，one side with your left hand，the other side with your right hand．Then you won't have a free finger to use in pointing while reading．If you move your head，place your chin (下巴) in one hand and hold your head still (静止不动的)．
If you read no more than one or two or three words at a time，you need to work very hard in learning to take in (吸收) more words at each glance (一瞥) as your eyes travel across the lines of words．
Even if you do rather fast now，you can learn to read even faster．As you probably have been told，the secret of fast reading is to take in whole groups of words as each glance．Read in through groups and force (迫使) your eyes along the lines of words as fast as you can to make them go．Anyone who practices doing these things will he able to read faster．
