[00:11.28]Unit 8 Science makes our life easy!
[00:19.00]1.Listen,look and read.
[00:24.24]What is science about?
[00:27.97]Science is all about finding out how and why
[00:31.76]things happen in the world around you.
[00:35.88]It's about everyday things like finding out
[00:39.26]why somebody catches a cold,how planes can
[00:43.29]fly in the air and why we need water to live.
[00:47.76]Science can help us explain why dinosaurs are
[00:51.21]extinct now.
[00:55.23]Science helps us understand how our world works.
[01:00.15]In science,we find out what happens
[01:03.59]and why some things happen in our world.
[01:06.38]For example:
[01:09.17]Why do we need medicine when we are ill?
[01:13.47]How can we see stars in the sky?
[01:17.35]How can we make our city cleaner?
[01:21.27]What kind of food is good for our health?
[01:26.60]What do scientists do?
[01:30.59]One of the first things scientists do
[01:33.96]is to ask questions.
[01:37.43]Then they try to answer the questions by looking
[01:40.90]closely at things.
[01:43.52]But who are scientists?
[01:47.26]Please look at the pictures and tell us
[01:50.03]why they need to study science to do their job.
[01:57.15]2.Listen,read and act.
[02:02.55]What are you doing?
[02:04.71]I'm writing an email to my friend.
[02:07.44]It's David,isn't it?
[02:09.77]No,it's Betty.
[02:11.68]The other day,she sent me some nice pictures.
[02:15.11]I just want to thank her.
[02:17.36]I see.Why don't you give her a call?
[02:20.16]It's much easier.
[02:22.01]But the telephone makes me nervous.
[02:24.20]I feel braver when I write emails.
[02:27.33]You are right.
[02:28.65]I'm afraid of talking in front of my class,too.
[02:30.91]Talking makes my mouth dry.
[02:33.57]We should speak to our friends often.
[02:36.63]Right.I need to talk to Helen now.
[02:38.99]See you tomorrow.
[02:45.69]8.Listen,read and answer.
[02:52.14]A great scientist
[02:56.87]Albert Einstein,a great scientist,
[03:00.38]told a story about his childhood.
[03:03.35]He said his interest in science all came about
[03:06.87]one day when he was playing with a compass
[03:10.06]his father had given him.
[03:12.48]The compass made him interested in science
[03:15.76]and he studied the compass carefully.
[03:18.96]He began to understand how it worked.
[03:22.86]"Games,all games have to be fun
[03:26.64]and have to make you think.
[03:28.94]They have to　bring new ideas into your head,
[03:32.69]answer all your whys."
[03:35.33]A compass to Einstein did not mean much,
[03:39.57]but his careful thinking helped him work harder
[03:42.98]at new things.
[03:44.26]We should all learn from Albert Einstein.
[03:52.60]Read aloud
