4 . How to Prepare for an Earthquake
An earthquake can be a very destructive natural disaster, particularly in the Pacific Rim region. After an earthquake, your home may be a mess and you might be left without a water supply or power.
· Create a disaster plan.
Form your plan and know what to do before the earthquake happens.
In a real earthquake, this is your number one defense. Drop to the floor, take cover under a firm desk or table and hold on firmly. Namely, drop and cover your head from falling objects. Stay there until the shaking stops.
·Learn basic first aid.
There are resources in your community to educate people on how to deal with first aid emergencies.
·Write down and share emergency contact lists.
This should include everyone in your home, office, etc.

6 . When Alex Lin was 11 years old, he read an alarming article in the newspaper about e-waste. The article said that people were throwing away their e-waste in places it should never go. This was dangerous, the article said, because e-waste contains poisonous chemicals and metals like lead. These harmful substances (物质) can leak into the environment, getting into crops, animals, water supplies — and people.
Alex showed the article to a few of his classmates. They were worried too. But what could they do about this problem with e-waste? How would they even start? “The first thing we did,” Alex says, “was to learn more about the problem.” Alex and his friends spent several weeks gathering information about the chemicals in e-waste and their effects on humans. They learned how to dispose (处理) of e-waste properly and how it could be recycled. “Then,” he says, “we had to find out what the situation was in our town. So we sent out a survey.”
What they found shocked them: Of the people who answered the survey, only one in eight even knew what e-waste was, let alone how to properly dispose of it. Alex and his friends went into action. They advertised in the local newspaper and distributed notices to students, asking residents to bring their unwanted electronics to the school parking lot. The drive lasted two days, and they collected over 21,000 pounds of e-waste.
The next step was to set up an e-waste drop-off center for the town and to find a responsible company to recycle the waste. That was when Alex and his friends learned another scary fact about e-waste — some irresponsible recycling companies don’t break down the e-waste and dispose of it safely themselves. Instead, they ship it overseas to countries such as China and Nigeria, where local environmental laws are not applied. “We checked carefully online to make sure the company we chose didn’t do this,” Alex says.
Because of the work of people like Alex and his team, more and more people are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s poisonous trash.”

7 . Natural disasters take many different forms and can happen without warning. Earthquakes, floods, volcanoes, droughts, typhoons, and hurricanes are all natural disasters.
The earthquake of 26 December 2004 resulted in one of the worst natural disasters in living memory. It was a massive (大规模的) underwater quake and occurred in the Indian Ocean. This caused a huge tsunami to cross the Indian Ocean. It destroyed coastlines and communities and brought death and destruction (破坏) to many people. The survivors needed fresh water, food and shelter as well as medical help. People from all over the world collect money to help them.
The surface of the Earth has not always looked as it does today; it is moving continuously although very slowly and has done so for billions of years. This is one cause of earthquakes, when one section of the Earth crashes with another. Scientists can predict (预测) where this might happen and the area between plates is called a fault line. However, earthquakes do not always happen on fault lines, which is why they are so dangerous and unpredictable.
All the disasters are very dangerous and continue to kill thousands of people each year, but they are nowhere near the most dangerous disaster to ever happen on earth. One type of event in the earth’s history has regularly killed millions of beings: asteroid impacts (小行星撞击). About once every million years the Earth is hit by a piece of rock and ice from space large enough to cause massive destruction (including earthquakes, volcanoes and ice ages) and sometimes to kill entire species. Sixty-five million years ago more than half the earth’s species were killed by such a disaster, including all the dinosaurs. Disasters on the Earth may seem dangerous, but the biggest threat to humans is likely to come from space.

8 . A flood can develop slowly, over time or rapidly, as in the case of flash floods which can develop in just a few minutes and without signs of rain.
Create an evacuation plan in case you have to evacuate your home. Pay attention to the safe areas you can go to. Prepare food kits for natural disasters that you can easily take with you if you have to leave your house.
If there is a possibility of a flash flood, leave your home and move to higher ground at once. Do not wait for instructions to move. Evacuation may also cause a shortage in the food supply.
While evacuating, avoid walking through moving water. Even six inches of moving water can make you fall. If you have to walk in water, walk where the water is not moving.
Do not drive into flooded areas. If floodwaters rise around your car, abandon (舍弃) the car and move to higher ground, when water is not moving or not more than a few inches deep.
A.They don’t know where to look for shelter. |
B.You and the car can be swept away quickly. |
C.Use a stick to check the ground in front of you. |
D.Be aware if the area you’re at is at risk of a flood. |
E.There is no telling when another flood may happen. |
F.It would help to store food for emergency situations. |
G.During these conditions, hunger becomes a very real problem. |
9 . The ocean covers more than 70 percent of the earth’s surface and the deep sea could contain as many as 100 million species. But it’s becoming worse. Overfishing, plastic pollution, rising sea levels, and climate change are to partly blame (责怪) for the ocean’s present state.
People are talking about plastics more than ever after recognizing the heavy effect the material has on our planet. Every year, thousands of seabirds, sea turtles, seals, whales, dolphins, and fish are killed after mistakenly eating plastics.
Keeping our coastlines clean is a simple way to help the planet. After a day at the beach, make sure you’ve taken everything with you, including rubbish.
Being mindful of what cleaning products you use is another effective way to reduce your effect on the earth. Chemicals like household cleaners can move through waterways and eventually end up in the sea, affecting the health of oceans and the animals in them.

F.Once you arrive at your destination (终点),be respectful of the life in the sea. |
G.Plastics take years to break down, some taking hundreds or even more. |
10 . The area in front of Janet and Jeffrey Crouch’s house in Columbia, Maryland, does not look usual for their neighbourhood. That is because the Crouches do not have a grass lawn(草坪). Instead, they have some small trees and many native plants.
In recent years, support for replacing lawns with native plants has been increasing in the US. It can be costly to keep a lawn looking good and green. But the Crouches had to spend much more money for the right not to have one.
People living in a house next to them complained to their homeowner’s association, or HOA. HOAs can make rules about the plants that homeowners in a neighbourhood are permitted to grow. Many HOAs require grass lawns. The HOA ordered the Crouches to pull out their native plants and put in grass. However, they refused. “We knew we were doing things that were beneficial for the environment, ” said Janet Crouch.
Lawns are called environmental dead zones in part because they provide no food or shelter for wildlife. They also do not support pollinators like birds, bees, and butterflies. Bee populations have been getting smaller in North America and may be getting smaller around the world.
There are other reasons that lawns are bad for the environment. They require a lot of water and chemicals. Large amounts of water can remove nutrients from the soil. After the water removes the nutrients, people buy even more chemicals to put on their lawns. Scientists say some of these chemicals might cause cancer and other health problems. There are over 16million hectares of grass lawns in the US. That means lawns use more water than any other irrigated(灌溉)crop in the country.
The Crouches’ battle against their HOA took three years. They say they spent $60, 000 fighting to keep their natural garden. They won. Because of their efforts, the state of Maryland passed a law that lets people grow native plants instead of grass, no matter what their HOA wants.
