It’s you and I who are to blame for the state of the earth. No question about it. It’s our life-style that is threatening life on Earth, so we must make the changes. The good news is that many of those changes are really quite simple, even enjoyable, but for every careful step we take as individuals, we must press government and industry to take a big step on our benefit. And we must start now. Tomorrow’s too late.

My aim this year is to persuade as many of my friends and colleagues as possible to choose the train, and leave their cars behind too. My gardens have been pesticide(杀虫剂)–free zones for years and I enjoy seeing more wildlife on my doorstep as a result; I’ve tried to reduce my contribution to water pollution too, by using environment-friendly, phosphate(磷)–free washing powder , and by no longer thinking of the toilet as a suitable waste-disposal(处理) point .

I ran after a young lady through town recently to give her back the piece of paper she had carelessly thrown away. She disappeared into a shop, and when I followed her inside and made my presentation, she was doubly embarrassed--she worked there, and the boss gave her a ticking–off too. I’ve started asking fellow drivers at gas stations why they aren’t using unleaded (无铅的) petrol . These are small things, but we have to start somewhere, and every little does help.

D．inform us of the good news

 

Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. Earthquakes happen along "fault lines" in the earth’s crust. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be predicted -- although scientists are working on it!

Most of the time, you will notice an earthquake by the gentle shaking of the ground. You may notice hanging plants swaying or objects wobbling on shelves. Sometimes you may hear a low rumbling noise or feel a sharp jolt. A survivor of the 1906 earthquake in San Francisco said the sensation was like riding a bicycle down a long flight of stairs.

The intensity of an earthquake can be measured. One measurement is called the Richter scale. Earthquakes below 4.0 on the Richter scale usually do not cause damage, and earthquakes below 2.0 usually can’t be felt. Earthquakes over 5.0 on the scale can cause damage. A magnitude 6.0 earthquake is considered strong and a magnitude 7.0 is a major earthquake. The Northridge Earthquake, which hit Southern California in 1994, was magnitude 6.7.

Earthquakes are sometimes called temblors, quakes, shakers or seismic activity. The most important thing to remember during an earthquake is to DROP, COVER and HOLD ON. So remember to DROP to the floor and get under something for COVER and HOLD ON during the shaking.

Which statement about earthquakes is not correct?

A. Earthquakes are the result of the sudden shock of the earth’s surface.

B. Earthquakes usually can be felt because they can last for a long time.

What can be inferred from the passage?

A. Most of the time, people can not feel or predict the earthquakes.  

B. Earthquakes are sometimes called temblors, quakes shakers or seismic activity.

C. The Northridge Earthquake in Southern California in 1994 caused severe damage.

D. When an earthquake happens, it is important to drop on the floor immediately.

What do you know about the sea? We know that it looks very pretty when the sun is shining on it. We also know that it can be very rough when there is a strong wind. What other things do we know about it?

The first thing to remember is that the sea is very big. When you look at the map of the world you will find there is more water than land. The sea covers three quarters of the world.

The sea is also very deep in some places. It is not deep everywhere. Some parts of the sea are very shallow. But in some places the depth of the sea is very great. There is one spot, near Japan,  where the sea is nearly 11 kilometers deep! The highest mountain in the world is about 9 kilometers high. If that mountain were put into the sea at that place, there would be 2 kilometers of water above it! What a deep place!

If you have swum in the sea, you know that it is salty. You can taste the salt. Rivers, which flow into the sea, carry salt from the land into the sea. Some parts of the sea are saltier than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers cannot sink! Fish cannot live in the Dead Sea!

In most parts of the sea, there are plenty of fish and plants. Some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are so small that it is hard to see them. Many fish live by eating these floating things.

The sea can be very cold. Divers who go deep down in the sea know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship!  They went down to the deepest part of the sea in it. They went down to a depth of eleven kilometers!

66. When does the sea look beautiful?

A. When it is calm.

B. When the weather is fine.

C. When there is a strong wind.

D. When there is a storm.

67. How much of the earth’s surface does land cover?

A. 15%                 B. 25%                  C. 30%                 D. 45%

68. Why does the author mention the sea somewhere near Japan?

A. To show that the sea in some places is very deep.

B. To show that the sea in some places is very shallow.

C. To show that its depth is 9 kilometers greater than the height of the highest mountain.

D. To show that its depth is 11 kilometers greater than the height of the highest mountain.

69. Which of the following statements about the Dead Sea is NOT true?

A. There are plenty of fish in it.

B. It is a safe place for swimmers.

C. It is extremely salty.

D. No fish can be found in it.

70. Why can’t people go very deep in the sea?

A. Because the deepest part of the sea is very cold.

B. Because the deepest part of the sea is very rough.

C. Because the pressure of the water at great depths is unendurable.

D. Because fierce fish usually live there.

Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't   1   it to be blue - the name has nothing to   2   the color of our closest celestial（天体） neighbor.

A full moon   3   on December 2. It will appear again on Thursday in time for the New Year's countdown.

"If you're in Times Square, you'll see the   4   moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.

The New Year's Eve blue moon will be   5   in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up  6   New Year's Day, making January a blue moon month for them.

However, the Eastern Hemisphere can celebrate with a partial lunar eclipse（月蚀） on New Year's Eve when  7   of the moon enters the Earth's shadow. The   8   will not be visible in the Americas.

A full moon occurs   9   29.5 days, and most years have 12.  10  , an extra full moon in a month - a blue moon - occurs every 2.5 years. The   11   time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't   12    again until 2028.

Blue moons have no astronomical   13   , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.

"`Blue moon' is just a   14   in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.

The popular definition of blue moon   15   after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar   16   a blue moon as the third full moon in a season with four full moons, not the usual three.

Though Sky & Telescope corrected the  17   decades later, the definition caught on. For purists（语言纯正癖者）, however, this New Year's Eve full moon doesn't even qualify as a   18   moon. It's just the first full moon of the winter season.

In a tongue-in-cheek essay   19   on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm    20  celebrating, I'll take a peek（眯着眼睛看） at that brilliant orb（天体） as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."
