   What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.
   Escaping a fire is a serious matter. Knowing what to do during a fire can save yourself. It is important to know the ways you can use and to show them to everyone in the family, such as stairways (楼梯) and fire escapes, but not lifts.
   From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving through windows with the least chance of serious injury (伤害).
   The second floor window is usually not very high from the ground. An average person, hanging by the finger-tips (手指尖) will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.
   Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked (泄露) into the room.
   On a second or third floor, the best windows for escape are those which open onto a roof (屋顶). From the roof a person can drop to the ground more safely. Dropping onto cement (水泥) might end in injury. Bushes and grass can help to break a fall

Imagine you're at a restaurant. You order a salad with beautiful green lettuce (生菜), nice red tomatoes, yellow peppers and cucumber. When it comes, you can't wait to take that first mouthful. But stop for a minute and think about how long it actually took to get to your plate. Not from the kitchen, but from the farm.

Let's take a look at a salad served in the United States. "Fresh" food, such as the lettuce, might be grown locally. But what about the other food on your plate? Nowadays, the country of origin (来源) of most of our fresh produce (农产品) - that's the place where produce was grown - is thousands of kilometers away. Produce was picked, washed, packed and brought to a center halfway around the world before it traveled to a store near you. So food which looks fresh has actually traveled in a refrigerated truck for a week.

But that isn't the only problem. Food needs transportation, and all forms of transportation cause air pollution. The farther food travels, the more gas is used, so more pollution is set free. Shipping fresh produce can add up to forty-five times more pollution to the air.

There is a solution, however. We can stop eating food from other countries, and we can buy fresh produce grown locally. The lettuce picked yesterday will taste a lot better. It'll also be healthier than the lettuce picked a week ago. Eating locally-grown produce also means that you eat more kinds. We forget that different fruits and vegetables grow in different seasons. Unluckily, this means we have to eat seasonal fruits and vegetables. That means we can't eat fresh summer fruits and vegetables in the winter. But we really shouldn't anyway!
