Use Compact Fluorescent Bulbs

Replace 3 frequently used light bulbs with compact fluorescent bulbs. Save 300lbs (pounds) of carbon dioxide and $60 per year.

Use Recycled Paper

Make sure your printer paper is 100% post consumer recycled paper. Save 5lbs of carbon dioxide per ream of paper.

Take Shorter Showers

Showers account for 2/3 of all water heating costs. Save 350 lbs of carbon dioxide and $99 per year.

Buy Products Locally

Buy locally and reduce the amount of energy required to drive your products to your home.

Carpool When You Can

Own a big vehicle？Carpooling with friends and co-workers saves fuel. Save 790 lbs of carbon dioxide and hundreds of dollars per year.

Don’t Idle in Your Car

Idling wastes money and gas, and generates pollution and global warming causing emissions. Except when in traffic, turn your engine off in you must wait for more than 30 seconds.

Buy Organic food

People in Shanghai can quench their thirst with high quality water if the Shanghai Water Authority (SWA) is able to make good on its word. It has vowed to make the city’s water match its status as a world class city.

   “The current tap water quality meets national standards, but, compared with that of the European Union and the United States, it still needs to be improved.” said the SWA’s director general, Hang Jiayi.

    In other developed countries, water fountains can be found almost everywhere—people do not bother with bottled drinking water.

    By 2020, the water of the Huangpu River will be treated to reduce the amount of organic waste in it. Major water works that draw water from the Huangpu will need more treatment facilities to improve the colour, texture, ammonia(氨)and nitrogen content before 2010.

    These treatment facilities are expected to cost 4 billion yuan, something that could affect the price of water, according to Chen Yin, SWA’s deputy director general.

    Chen said that replacing water pipes was also a key project. The city’s aged pipes are mostly to blame for the bad water quality.

    The SWA has started the water facilities renovation(更新)work, including the more than 14,000 kilometres of indoor piping, 107,000 tanks on top of the buildings, and more than 6,000 underground facilities.

    World Water Day came on March 22, and this year’s theme is “Water for the future”. Beijing is also drawing up plans during China’s Water Week, which runs until March 28.

    By 2010, the water for the Shanghai EXPO is to be above World Health Organization standards. And, the people of Beijing will be able to drink their tap water as well.

People in Shanghai can drink their tap water_____.

   A. by 2020       B. in the first half of this year     C. by 2010      D. by 2008

What step need not be taken in order to improve the tap water?

A. The water of the Huangpu River will be treated.    B. Aged water pipes will be treated.

C. Water facilities must be renovated.                   D. Water fountains must be found.

Which is the correct statement according to the passage?

A. The tap water quality in Shanghai hasn’t met national standards.

B. World Water Day fell on March 22 this year.

C. The people of Beijing cannot drink their tap water now.

D. The treatment of the water of Huangpu River has been finished.

What is the main idea of the passage?

A. The cost of treating the tap water.

B. How to reach the water standards of developed countries.

C. The project for making tap water drinkable in Shanghai and Beijing.

D. The progress of treating the water of Huangpu River.

Recently 3 kinds of foods are very popular in the US.

Convenience Foods

Instead of buying only fresh foods, Americans buy many more convenience foods. These are foods which are ready partly or completely prepared. There are also many canned convenience foods, such as soups and vegetables.

Convenience foods save time and trouble. They are popular with people who are busy or who don't like cuisine or washing dishes. But they often cost more money than fresh, unprepared foods and may contain man-made additives. Also they don't taste as good as home cooked foods.

Health Foods

In the 1960s, a "back-to-the earth" movement was started by young people in the US. The movement was a reaction against the harmful effects of technology. Many people now prefer natural and organic foods to the prepared foods sold in food stores.

Diet Foods

These, days Americans are more and more concerned with their weight. American supermarkets sell a variety of diet foods as diet soft drinks, diet candy, and diet salad dressings. Each year dozens of new diets are popularized. However, some of the diet foods are unbelievable. There are tricks in their advertisements.

US researchers have found traces of an ancient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life.

    The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the University of Colorado.

    “This is the first clear evidence of shorelines on the surface of Mars,”said Boulder’ s research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters.

   “The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.”

   Analysis of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤积) sediment (沉积) which formed a delta (三角洲).

  “Finding shorelines is a great discovery to us,” said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry.

    Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago.

The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study.

 Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.

1.The size of the lake found on Mars is ______.

A. 80 square miles                  B. 1,500 square miles

C. 3.4 billion square miles             D. 300 million square miles

2.When the lake existed, the weather on Mars was ____.

A. hot and wet      B. wet and warm         C. cold and dry     D. cold and wet

3.Why do scientists think deltas near the lake may hold secrets about past life on Mars?

A. Because similar places on Earth have become natural deposits of markers of life.

B. Because someone has put secrets about past life on Mars there.

C. Because past life has been found in other deltas on Mars.

D. Because some people are said to have already seen life marks there.

4.Which of the following statements is NOT true according to the passage?

A. The Noachan epoch was a wet and warm era.

B. The lake might have existed 3.4 billion years.

C. The discovery can’ t fully prove that the Mars once hosted life.

D. The lake traces prove that there exists life on Mars now.
