Unit 2
[00:03.08]Plant a Plant!My Grade One Tree My name is Anna.
[00:11.65]When I was in Grade One,I got a little tree.
[00:17.11]Everyone gets a little tree in Grade One.
[00:22.07]It's a spruce tree.See?When I brought my tree home,it was very little.
[00:30.22]It was about twenty centimetres tall--about as tall as my hand.
[00:37.49]I planted it in a pot.My mum helped me.I watered my tree a lot.
[00:45.14]In the pot,the soil got dry fast.Why did we plant my tree in a pot?
[00:54.10]Why didn't we plant it in the ground?We knew my tree was going to be big.
[01:02.56]We didn't know where we wanted a big tree.
[01:07.32]My tree slowly grew. After two years, it needed a new pot.
[01:14.45]Its roots had grown too big.So we planted it in a bigger pot.
[01:21.21]This spring,in May, we planted it in the garden.
[01:26.86]I'm in Grade Seven now and my tree is about fifty centimetres tall.
[01:34.62]It's up to my knees.Trees are good.
[01:39.76]They help clean the air.Their roots take care of the soil.How?
[01:47.31]The roots stop the wind from blowing the soil away.
[01:52.88]They stop the rain from washing the soil away.
[01:58.15]I think that's why everyone gets a tree in Grade One.
[02:03.72]The world needs more trees!What does Anna mean by "the soil got dry fast"?
[02:12.86]This is what she means:she watered the soil,but soon it was dry again.
[02:20.80]A garden is a place outside.You grow plants in it.
[02:27.07]Many people grow flowers and vegetables in their gardens.
[02:32.82]Gardens are usually near your house.What's air?
[02:38.77]Look it up in the dictionary at the end of your Student Book!
[02:44.34]Seed E-mail To:danny@ intersaurus.com Subject:Seeds!
[02:55.26]From:[email protected] Date:19/03 8:38PMHi,Danny.
[03:06.93]Hi,Danny.We're doing a new project in school this week.
[03:12.89]We're learning about how plants grow. Our teacher gave each of us a pot.
[03:20.15]Then we each chose a seed.I planted a flower seed.
[03:26.32]I put it into my pot,and covered it with soil.
[03:31.77]Then I watered it.We made posters to show how our plants will grow.
[03:39.22]My seed will soon sprout.Then it will grow into a beautiful flower!
[03:46.48]This project is teaching me a lot of new English words.
[03:51.94]"Sprout":the first thing the seed does after you water it.
[03:57.58]"Stem":the long green thing that grows up.
[04:02.83]"leaves":the green things that grow on the stem.And "bud":the baby flower!
[04:11.90]Have you ever planted a seed, Danny?

[04:34.78]Date:18/03 7:02 AMDear Li Ming,Yes,I have planted a seed!
[04:48.44]We are also learning about plants in school.
[04:53.59]I told my teacher that I wanted to plant a donut.That way,
[05:01.95]I could grow lots of donuts.But the teacher laughed and said no.
[05:10.13]I asked him if I could plant an apple seed.
[05:15.59]He said that apple seeds take years to grow.That's too long!
[05:23.74]Then he said,"In Canada,we grow a lot of wheat.
[05:30.40]Maybe you should plant a wheat seed.
[05:35.15]Then you will learn how wheat grows."So I think I will plant a wheat seed.
[05:43.20]It will be fun to watch it grow!
[05:47.95]Danny How Do You Plant a Seed?What happens when you plant a seed?
[05:59.13]When a seed starts to grow,the roots sprout first.
[06:04.88]Next,the stem sprouts.As the stem grows,
[06:10.83]it pushes up through the soil.
[06:15.28]Soon you will see a little green stem above the soil.
[06:21.20]Then,the stem will grow two little leaves.
[06:26.48]Is it ok ay to plant a seed upside down?
[06:31.76]Yes!you can plant a seed upside down.
[06:37.01]It will always send its roots down and its stem up.
[06:44.66]Danny:What does "upside down" mean?I am upside down now
[06:51.61]What happens if you plant a seed too deep?
[06:56.94]Seeds need air to grow.If you plant a seed too far down in the soil,
[07:04.70]it will die.Remember not to cover your seed with too much soil.
[07:14.16]What happens after the seed has sprouted?
[07:18.83]Soon your new plant will grow more leaves.
[07:24.08]Look after your plant and it will be healthy.
[07:28.84]It will grow big and have lots of leaves.Will your plant make flowers?
[07:36.10]First the plant makes buds.As the plant grows bigger,
[07:43.07]the buds bloom.Now your plant has flowers!
[07:48.82]Do you remember why plants have flowers?
[07:53.78]Because the flowers make seeds,and the seeds make new plants.
[08:01.05]FASCINATING FACT
[08:04.31]The double coconut tree has the biggest seeds in the world.
[08:10.48]They are very heavy--some are as heavy as you!
[08:16.22]The tallest plant in the world is the giant redwood tree.
[08:22.10]It grows from a seed smaller than a fingernail.
[08:28.06]Seeds come in all sizes.Some are big;
[08:33.80]some are small.Danny:"Giant" means very,very tall--taller than me!
[08:43.08]Brian:What's a "fingernail"?A fingernail grows on the end of your finger.
[08:50.02]This is a fingernail.What's Wrong with Danny's Seed?
[08:59.40]Danny's wheat seed isn't growing.
[09:04.05]Danny has put his pot in the refrigerator
[09:09.20]because that's where his mother puts the bread.
[09:14.06]Bread is made from wheat seeds!
[09:18.92]But then he thought the refrigerator might be too cold for his seed.
[09:25.39]So he put a scarf around the pot to keep the seed warm.
[09:31.56]Why isn't the seed growing? Danny doesn't know.
[09:37.41]Danny:What's wrong with my plant?Then Danny has an idea.
[09:44.25]Maybe Li Ming can give him some advice.Danny phones Li Ming.
[09:51.52]The phones rings and rings.Finally,Li Ming answers.
[09:57.86]He sounds very tired."Good afternoon, Li Ming!"says Danny.
[10:05.44]"Are you eating your lunch?""It isn't afternoon in Shijiazhuang,Danny,
[10:12.39]"says Li Ming.
[10:15.55]"It's four o'clock in the morning!""Oh,no!"says Danny.
[10:22.60]"Do you want to go back to bed?""I will soon,"says Li Ming.
[10:29.76]"But first,tell me why you phoned.""Has your plant sprouted?"asks Danny.
[10:38.22]"Yes,"says Li Ming.
[10:42.48]"It already has four leaves!""My wheat seed isn't growing,"
[10:49.85]says Danny.
[10:53.01]"What am I doing wrong?""Have you covered it with soil?"asks Li Ming.
[11:00.66]"Yes,lots and lots of it,"answers Danny."No,Danny," says Li Ming.
[11:09.62]"Cover it with a little bit of soil
[11:13.78]How about water?""Do seeds need water?"asks Danny.
[11:20.72]"Maybe I'll water mine.""Next,give it lots of warm sunshine,"says Li Ming.
[11:29.40]"Then it will soon sprout.""I will take my pot out of the refrigerator,"
[11:37.26]says Danny."Then I'll water it and put it next to the window.
[11:44.52]Thanks,Li Ming! You can go to bed now!"Plants Are Interesting!
[11:54.97]What plant is like a dinosaur?Dinosaurs lived 150 million years ago.
[12:05.03]The ginkgo tree lived then,too.
[12:09.47]Do we have any dinosaurs now?No!Dinosaurs are extinct.
[12:17.12]There are no dinosaurs today.Do we have ginkgo trees?Yes!
[12:24.78]Gingko trees grow in China.
[12:28.83]Do we have any other plants and animals from dinosaur times?
[12:34.89]No!Ginkgo trees
[12:39.04]are the only living thingsfrom the time of the dinosaurs that live today.
[12:45.70]Danny:Hey!I'm here! I'm alive!I'm not extinct!How fast can plants grow?
[12:56.28]Bamboo can grow one metre a day.It is the fastest growing plant in the world.
[13:04.14]What is the biggest flower?
[13:07.98]The stinking corpse lily has the biggest flowers in the world.
[13:14.33]They are about one metre wide and can weigh seven kilograms.
[13:20.37]How many people have seen this flower?Not many!
[13:25.80]The flowers smell so bad,nobody wants to go near them!
[13:32.64]This plant blooms once a years.It grow in the jungles of Asia.
[13:39.30]Danny:"What does"stinking" mean?When something stinks,it smells bad.
[13:49.57]What do you use to smell?Your nose!Brian:What's a"corpse"?
[13:56.83]A corpse is a dead body.You can look up
[14:01.98]"dead" in your dictionary.Jenny:What's a"jungle"?
[14:07.65]Trees grow in forests.Forests are big.A jungle is a special forest.
[14:16.19]It is a warm,wet forest with very big trees.Do plants sleep?
[14:24.65]Yes.At night,plants cannot make food because there is no sunlight.
[14:32.41]Their leaves can't get energy,so they go to sleep.Can plants move?
[14:40.88]Plants cannot move from place to place.
[14:45.63]But plants can move their leaves and flowers.
[14:51.48]They can turn their leaves and flowers towards the sun.
[14:57.36]Some plants move their flowers in a different way.
[15:02.64]They move their flowers to get food.These plants are predators.
[15:09.40]Danny:Do you remember the word "predator"?A predator eats other living things.
[15:17.55]Usually,predator plants eat insects,
[15:23.01]but sometimes they eat small animals and birds.
[15:28.47]The biggest predator plant is the tropical pitcher plant.
[15:34.24]It catches insects inside its big flowers.
[15:39.60]The tropical pitcher plant lives in the jungles of Asia.
