[03:29.76]Most of us think that people are the most important things on Earth¹⁶,
[03:35.04]but we aren't.
[03:38.28]We are really much less important than plants!
[03:43.35]If all the people on Earth die¹⁷ tomorrow,life will not stop.
[03:49.51]The plants animals and everything else will go on living.

[04:02.16]The air will change and neither¹⁸ animals nor¹⁹ people
[04:07.72]will be able¹¹ to live in that air.

[06:12.58]Read about these plants and then,in groups,answer the questions.
[06:19.56]Not all plants are useful²³ to us,but all of them are very interesting.
[06:25.91]Did you know that some plants even²⁴ eat insects²⁵ and small animals?
[06:32.39]These plants can't get enough food from the ground,

　　[06:35.47]so they need to eat something else.
[06:39.62]This plant smells very sweet and its leaves are red.
[06:44.66]Many insects love bright colours like red.Red means²⁶ food!
[06:51.14]When they see the red leaves on this plant, they fly down for supper!
[06:56.99]but the leaves have lots of long hairs on them.
[07:02.14]If an insect touches the hairs once or twice²⁷,
[07:07.28]the two sides²⁸ of the leaf shut²⁹ together at once.
[07:12.33]It takes less than half a second!
[07:17.08]The poor insect is now inside³⁰ the leaf and it cannot get out.
[07:22.83]it has become food for the plant. The plant eats it slowly³¹.
[07:29.99]It takes the plant about 12 to 15 days to finish its meal³².
[07:36.23]Small plants like those can catch insects,
[07:40.88]but a few³³ larger ones can even catch small animals,
[07:46.34]this plant has special leaves and the hairs on its leaves shine³⁴.
[07:52.22]When insects and animals see its leaves they come closer to have a good look.
[07:59.06]If an insect jumps onto³⁵ a leaf,the hairs catch it.
[08:05.43]These hairs move very quickly.
[08:10.08]They can move 180°in less than a minute!
[08:16.14]The hairs hold the insect so it can't move,and the leaf closes round it.
[08:23.80]Then,the plant begins to eat.
[08:28.06]When it has finished³⁶ eating,the hairs open,
[08:32.73]the leaf changes back to its usual shape,
[08:37.41]and the wind blows away the insect's dry,empty body.
