[00:06.09]Simon like exciting films,but Debbie prefers nature films.
[00:14.52]One day, she said,'Do you want to watch this video,Simon?
[00:21.16]It's about strange living things.they can be very or huge!
[00:29.31]Some have lots of bodyguards1 to protect them.
[00:34.87]Some live for thousands of years.And some are killers3 and kidnappers4!
[00:44.33]Simon said,'It sounds really exciting!'
[00:49.89]But he had a surprise when he watched it.
[00:54.57]Here are some excerpts5 from it.Tgw Weird6 World of Plants
[01:02.51]This is the Venus Fly Trap.
[01:06.48]It has two special leaves,and each leaf has several hairs in the middle.
[01:13.14]If an insect touches one of these the leaves start to shut together.
[01:19.80]The insect often tries to run away.
[01:24.45]But the plant moves more quickly than the insect.
[01:29.73]The victim is trapped in a little prison.
[01:33.68]Soon it dies, and the plant gradually absorbs it.
[01:39.11]Plants live the longest of all things on Earth.
[01:43.55]A Bristlecone Pine in California is 4,700 years old
[01:50.39]and is still alive older than any written history.
[01:55.96]Plants can be as small as one cell,like the millions of tiny plants in the seas.
[02:02.72]One of the smallest is the Lichen7 plant which grows on stones.
[02:09.49]It is probably the plant which grows the most slowly.
[02:14.77]It can take a hundred years to grow a few centimetres.
[02:20.51]But plants can also be as big as the Giant Redwood,
[02:25.55]the world's most massive living thing.
[02:29.50]One tree in California is 84 m high
[02:35.38]and probably over two thousand tonnes in weight.
[02:40.24]No other type of tree grows higher than the Giant Redwood.
[02:45.56]The Dead Horse Arum attracts flies by looking and smelling like dead meat.
[02:52.33]Once they get inside the plant,it shuts a door,
[02:58.29]and keeps them prisoner for a night.
[03:02.41]During the night, it drops pollen8 on them.
[03:07.06]It releases them the next morning covered in pollen,
[03:12.52]so that they can go and carry the pollen to another Arum.
[03:17.80]One type of Acacia tree in South America encourages ants to live in it.
[03:24.96]The tree provides the ants with a home(in special branches)
[03:31.30]and with food (little pieces of protein at the end of some leaves).
[03:38.07]In return,the ants defend their tree as fiercely as they can.
[03:44.00]They attack any other insect or animal which comes near,
[03:49.07]and even remove other plants growing near it

[07:05.33]When we talk to people, we must use our voices
[07:10.68]so thatour listeners can underst and us easily.
[07:15.54]We should:speak loudly enough to be heard;pronounce words correctly;
[07:24.92]stress words or syllables9 that we think are important;
[07:30.17]let our voices rise or fall at the end of sentences,clauses or phrases
[07:37.74]which are often shown by punctuation10 marks;
