SAVING THE ENVIRONMENT: ONE HOME AT A TIME
Pollution can be seen not only throughout the world, but also in our own homes. It comes from household
chemicals, the amount of water people use and the waste people produce and throw away. What can be done
to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.
First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce
the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place
plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.
Second, we need to watch the amount of water used in the home. It can be conserved by taking short
showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully
loaded, or simply turning the faucet off while brushing your teeth.
Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste
effectively. For example, grass clippings and food scraps can be made into compost for plants. The average
person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.
If we do our part in our own homes, we can help keep the planet from becoming more polluted.
Question 36: Pollution can be caused from the following sources EXCEPT______.
A. water in rivers B. water from households C. wastes D. household chemicals
Question 37: Recycling can help us ______.
A. never cut down trees B. use products again and again
C. place garbage bins easily D. produce more paper products
Question 38: In order to save water, we can do all of the following things EXCEPT______.
A. take short showers instead of baths B. repair leaky faucets
C. fully use the washing machine D. turn the faucet off while brushing your teeth
Question 39: Recycling helps to reduce waste because______.
A. plants need to develop B. a person can do it in his home
C. waste can be recycled and reused D. an average man produces compost for plants
Question 40: The word "It" in paragraph 2 refers to ______.
A. cutting down B. the number C. recycling D. effort

Mercury is the smallest member of the sun's family. It is only 3.100 miles across. It is also the sun's swiftest planet. Its yearly journey round the sun is only 85 days.
Mercury always keeps one side towards the sun. On this side it is always day, on the other side always night. We only see the lighted side.
Mercury appears to us like a yellowish orange star. The nearest planet to the sun, it is always seen near the sun, either just before sunrise or soon after sunset. People sometimes call mercury the morning star or evening star.
Mercury is half the size of the earth. Because it is much lighter, it has much less gravity. If you can visit Mercury in a spaceship, you will find it a strange world. Its low gravity makes you feel very light. If your weight on earth is 100 pounds, your weight on Mercury is only 27 pounds. Looking at the sun from Mercury, you can see that it's much more brilliant than it is seen from the earth. And the yellow centre of the sun appears three times bigger from Mercury.
On its lighted side, Mercury's temperature is about 300 degrees centigrate. But the dark side is extremely cold, but 150 degrees below zero so mercury is probably the coldest as well as the hottest of the planets.

The Internet is growing and becoming a part of everyday life. No one can deny the benefits that the internet brings. I agree that the Internet is the most useful media today.
First, the Internet is a very useful tool
. We can get information on every aspect very quickly and conveniently. We can read e-books or check weather conditions. Through the internet, we can look at the prices of certain consumer goods.
Second, the Internet is a source of entertainment. We can watch a movie, listen to recent music albums, play games, read novels, ....
Finally, the Internet is an educational medium. We can learn foreign languages, look up information. We can attend online courses. Internet is almost an unlimited educational resource for you to get.
Today, the Internet is a highly effective tool for communication, information gathering and collaboration among remote locations. Millions of people around the world are using the Internet to communicate, share information, create new associations, and so on.
The downside is that the Internet can be addictive. Some people can not live without it. They have no real friends and when the Internet is down, they are angry.
Internet has some rivals but more and more people handle the Internet like phone, or radio. They use it to have fun and work, and I think living now without internet would be quite difficult.
But try to use the internet effectively.
I would like to end here, I hope everyone comments and comments to my rhetoric today is more perfect
There are many varieties of spider in the American Southwest, but none receives more respect than the western black widow, Latrodectus Hesperus. This poisonous spider, also called the “hour-glass” or “shoe-button” spider for the shape of the red markings on its abdomen, produces a venom 15 times more powerful than that of a rattlesnake. However, few deaths can be blamed on this insect because bites are rare and only a small amount of poison enters the body.

There are many varieties of spider in the American Southwest, but none receives more respect than the western black widow, Latrodectus Hesperus. This poisonous spider, also called the “hour-glass” or “shoe-button” spider for the shape of the red markings on its abdomen, produces a venom 15 times more powerful than that of a rattlesnake. However, few deaths can be blamed on this insect because bites are rare and only a small amount of poison enters the body.
The female adult black widow may reach a length of 1 ¼ inches, while the smaller male averages ¼ inch long. The adult female has a shiny black bulb-shaped abdomen, which distinguishes it from the male of the species. The male is generally brown with red and white markings on its flat underside.
The female adult deposits its eggs in specially constructed sacs that hold from 50 to 250 eggs. The tiny pale spiderlings hatch within a few months and gradually develop into adults in one to two years. Some females live up to three years. The male does not fare so well, as it sometimes suffers the fate of being consumed by the female after the summer mating season.
