Why do earthquakes happen? Scientists believe that the surface of the earth is covered by a number of moving plates. Sometimes two plates move towards and push against each other. Sometimes they stop for years but at other times they jump and an earthquake is felt. BecauseListening textof the movements of these plates,
California, China and Japan have
a lot of earthquakes. You can see the
result in San Francisco where the Pacific
plate meets the North American plate.
When the 1906 earthquake happened,
the Pacific plate jump 5 to 6 metres to
the north.Part 2
China is a country where many earthquakes happen. The Pacific plate is pushing China from the east and the Indian plate is pushing China from the southwest. The power of this movement created the Himalayas and Mount Qomolongma. It now causes earthquake in China. We cannot stop earthquakes but we can do things to make sure they do not destroy whole cities. First it is not a good idea to build houses along the line where two plates meet. Second, if you think there may be an earthquake, make sure to build houses on rock rather than sand. Third, you must make the houses as strong as possible. Weak buildings will fall down in an earthquake, but strong ones may stay up.Keys to exercise 1 on page 63as usual

Ever since the San Francisco earthquake,
all children in California have been taught
what to do during an earthquake.
Part 1
Teachers: Now, students, do you remember
what we should do before an
earthquake comes?S1: We must make a list of things. It
should tell us what to do, where to be
safe and who to contact.
T: Good. So first what should we do?
S2: We should “drop, cover and hold”.
T: Excellent. Now what does that mean?
S1: We must drop to the floor and cover
our heads with our hands. T: Right?
S3: We must hold onto the furniture so it
doesn’t move away from us during the
earthquake.
T: Well done. So don’t forget. It’s always
“drop, cover and hold”.Part 2
T: Now suppose you are outside when an earthquake comes. What should you do?
S3: Go to an open space away from buildings, trees or power lines.
S1: I should tie the television to a table so it won’t move. I should make sure that the bookcases are already tied to the wall.T: Fine, but what should you do if you
are alone when the earthquake starts?
S2: Ring a family friend to tell them
where I am and collect my personal
earthquake bag.T: Quite right. You’ve done a great job.
Now for your homework I want you to
think about what to put into your
earthquake bag. We’ll discuss tomorrow.Make sure that you only take essential things with you. They must last you five days.Speaking task on Page 67personal washing thingsfood and chocolate barsimportant papersbowls and chopsticksidentity cardcandlesbottle of watermoneypersonal washing thingsa bottle of water moneytorchmobile phonefood and

personal earthquake bag?
S2: If we have to collect things we need
for five days, the most important
things will be the bottle of water, candles, money and personal washing things. That makes four, do you agree?S1: Yes, they sound good choices. I also think we need a torch, a mobile phone and a blanket. Another one?
S2: OK. But now we have difficulties. I would like food and sweets. We’ll really need food if we’re to be on our own for five days before rescue comes.
S1: No, I don’t agree. Food and sweets is a good idea but the medicine would also be very useful.S2: I agree. So we have to choose whether to take the food and sweets and the medicine to make our eight items.
S1: OK. Now, let’s make the list: water, candles, money and personal washing things, food and sweets, a torch, mobile phone and blanket. If we want to add the medicine as well, what can we remove?S2: Well, the candles and the torch do seem to be the same. Why don’t we remove the candles (in case we don’t have matches) and replace them with the medicine?
S1: Yes. That seems to solve the problem. OK. Let’s put the medicine in and take the candles out. Now our list is complete. Let’s tell the class our ideas and see if they have the same ideas…What are you going to do if
an earthquake happens?If you are……SpeakingSuggest answer If you were sleeping in your bedroom when the quake happened, you would get up quickly first, next you would wake up your family and your neighbours. Then you could run to a safe place. So that you could escape being trapped or killed.Remember: These thing should be avoided:standing close to a building
(because it may fall on you if it
is weakened by the earthquake.)
2. standing under a tree
(because it may fall on you)
3. going too close to power lines

by electricity if they fall on you.)A posterWhat the poster is
