It’s important to prepare(准备) for earthquakes because you don’t know where you will be when an earthquake happens. Earthquakes may happen at any time, so prepare some things for your home, office and car.

1. Clothes.

If you live in a cold place, you must keep warm. You might not have heat after an earthquake.

Think about your warm clothes.

2.Flashlights(手电筒) and spare batteries.

Keep a flashlight beside you bed, at your office and in your car. Do not use matches(火柴) after an earthquake until you are sure that no gas leaks(气体泄漏).

Prepare a radio and some spare batteries. Most telephones will be out of order, so radios will be your best source of information(信息来源).

3. Food and medicine.

It’s always a wonderful idea to keep some food on hand. For example, some biscuits, some canned food, milk and some other drinks for at least 72 hours. You’d better get some necessary medicine for your family.

4.Water.

A person needs at least 1/2 gallon(加仑) of water daily just for drinking. Store at least 1 gallon of water for a person every day and be prepared for 72 hours. It is suggested that you buy bottled water. Do not open the bottle until you need it. Also, do check the “use by”date.
