Can you protect our Planet Earth? You may think it impossible, but you can begin by taking some small, but
important, first steps. Many children and their classes in the USA are starting some projects.
Children Campaign Against Waste
Children are paying attention to the packaging (包装) of the things they buy. Packaging includes all the things
you throw away when you unwrap anything new. One third of all rubbish is packaging. Mrs. Perez"s 4th grade
class decides to make their school and neighborhood know the waste in packaging. They want people to think
before they buy. They also want to let people who make the products know that they want less waste in
packaging. So they start a campaign to help people change how they shop.
Class Project: Campaign Against Waste
·Find out the facts. Use the websites to find out how much waste comes from packaging.
·Go on a trip to the shops. Take notes about how products, such as CDs, are packaged. Report on
how much will be throw away.
·Say no to bags. If we don"t need one, we don"t use one.
·Make posters to tell others what they can do.
·Talk to our families and friends about what we learn.
·Write class letters to the people who produce our favorite products. Ask them to reduce packaging. |
答案
Class Project: Creek Clean Up
·Write a letter to the mayor (市长) asking her to let us have a clean-up day at Carrollon Creek. Ask
her for garbage cans to keep rubbish.
·Make posters inviting others to help.
·Ask parents to come along and help on Clean-up Day.
·Choose a day for the big Clean Up! |

| 阅读理解。 | Plants and animals, including humans, need food and water to live on. These are from the natural resources
(资源) on Earth. To protect these resources, we need to keep the air clean and the water drinkable. We need
to keep the soil healthy. How do we do that?
* Protect the land
The soil that covers fields and farms provides much of the food we eat. Human activities such as plowing (耕) fields, mining (采矿), and building highways can destroy (破坏) the land. Erosion happen when wind and
water carry away the soil. Soil erosion can turn rich farmland into a desert wasteland. So does this mean we
shouldn"t build a highway or plow a field? Of course not. But it does mean we might think about Earth-friendly
ways of doing those things.
Today farmers plow their fields in different ways to prevent erosion. They try to use less water for their
crops. They keep animals from eating the growing grass in just one area. Farmers also plant trees to prevent
erosion from happening.
* Save the Trees
Another human activity that damages the land is deforestation (采伐森林). People take away a large number
of trees from a forest. Millions of square kilometers of forest disappear each year. When this happens, many
plants and animals lose their places to live. They may die out, or become very few. Scientists haven"t even
discovered all the living things in the forest. We may be losing some without even knowing they are there.
Trees absorb (吸收) and use carbon dioxide (二氧化碳) when they make food. Environmentalists encourage
careful management of the forests. They ask people to replant trees after they cut down the forest.
* Recycle, Reuse, Reduce
People throw a piece of paper into the wastebasket after using it. The paper becomes trash. Where does
the trash go next? Much of our trash ends up in landfills (垃圾填埋地). They take up valuable land and
sometimes pollute the water, air, and land around them. More than a third of the trash in landfills is paper.
Recycling, reusing, and reducing what you throw away can cut down on the need for more landfills. In fact,
we can recycle about eighty percent of household trash. | | 1. What does the underlined word "erosion" mean? | | [ ] | A. Plowing fields and mining.

One-third to one-haft of the earth"s population is under-nourished (营养不良的) even though more than the
necessary food for everyone on earth is available (可获得的).
Many nutrition experts (营养学家专家) say that one of the reasons people starve is that they are willing to
eat only the kind of foods they are used to. For example, enough rice to feed 1000 Chinese would be left to
spoil among Eskimos, who don"t eat rice. A store house full of bacon that would be food in many places
around the world would mean nothing to millions of East Indians, who won"t eat pork (猪肉) for religious
reasons. Another group of East Indians, called Hindus, won"t eat beef because their religion forbids it. Instead
of being butchered, cows are allowed to roam (闲逛) freely in the streets in Indian cities.
Thousands of scientists in all parts of the world are working to change soybeans (黄豆) and fish meal into
food that people of different nationalities will eat. Both soybeans and fish meal are high in protein (蛋白质) and
are available in large quantities. These scientists feel that human eating habits are often at the bottom of the
world-wide food problem. | | 1. What is the main idea of this passage? | | [ ] | A. The World Health Organization says people are starving.
B. There is enough food for everyone.
C. People"s eating habits are one of the causes of the world-wide food problem.
D. Scientists are malting food from fish meal. | | 2. This passage is written _____. | |
| [ ] | A. to explain one of the reasons people die of starvation
B. to explain why there are always starving people
C. to persuade people to eat food of soybeans and fish meal
D. to describe the eating habits of the East Indians | | 3. East Indians won"t eat pork _____. | | [ ] | A. because they don"t know what pork is
B. for religious reasons
C. because they prefer to starve
D. for health reasons | | 4. Cows are free to _____ in the streets in Indian cities. | | [ ] | A. be butchered
