Can plants eat people? Probably not, but there are many plants that eat meat.Some of them are big.And they can eat small animals.One famous meat-eating plant is the Venus flytrap(捕蝇草).
The Venus flytrap is a very strange plant.It grows in dry parts of the United States.Its leaves are like the pages of a book.They can open and close very quickly.Inside the leaves, there are three small hairs.If a fly touches one of the hairs, the leaf closes quickly.The fly cannot get out.In about half an hour, the leaf presses the fly until it is dead.Then, the plant covers the fly.Slowly, the plant eats the fly.
Why do plants do it? Most plants get what they need from the sun, the air, and the ground.In some places, the ground is very poor.It doesn’t have all these important things, especially nitrogen(氮).Animal meat has a lot of nitrogen, so some plants eat meat to get what they need.Let’s hope that some of the bigger plants don’t get the same idea!

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.
