[03:18.35]Which are more important 15 people or plants?

[03:29.76]Most of us think that people are the most important things on Earth 16,

[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 die 17 tomorrow,life will not stop.

[03:49.51]The plants animals and everything else will go on living.

[03:54.79]But,if all the green plants die,Earth will become a very different place.

[04:02.16]The air will change and neither 18 animals nor 19 people

[04:07.72]will be able 11 to live in that air.

[04:11.66]All living things need plants to make the right kind of air.

[04:17.23]But they also need them for something else-food.

[04:22.27]Living things need food to grow,but only plants can make their own 20 food.

[05:06.00]And,if they die, we all die.

[06:08.33]Lesson 12  Exercise 1

[06:12.58]Read about these plants and then,in groups,answer the questions.

[06:19.56]Not all plants are useful 23 to us,but all of them are very interesting.

[06:25.91]Did you know that some plants even 24 eat insects 25 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 means 26 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 twice 27,

[07:07.28]the two sides 28 of the leaf shut 29 together at once.

[07:12.33]It takes less than half a second!

[07:17.08]The poor insect is now inside 30 the leaf and it cannot get out.

[07:22.83]it has become food for the plant. The plant eats it slowly 31.

[07:29.99]It takes the plant about 12 to 15 days to finish its meal 32.

[07:36.23]Small plants like those can catch insects,

[07:40.88]but a few 33 larger ones can even catch small animals,

[07:46.34]this plant has special leaves and the hairs on its leaves shine 34.

[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 onto 35 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 finished 36 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.
