Ice volcanoes erupted on the shores of Lake Michigan last weekend, and an employee from National Weather Service ( NWS) caught sight of an astonishing scene on the spot. “You never know what you'll find at the lake until you go out there," the employee said, "Today it were volcanoes. ”
Despite their nickname, ice volcanoes aren't really volcanoes at all. They form at the edges of lakes, where thin sheets of ice form, and water shoots through holes in the ice, Water flows beneath the ice sheet and builds up enough pressure to push water to the surface. If the air above is cold enough, the released water freezes over the surrounding ground, forming a mini volcano of sorts.
Ice volcanoes can be very dangerous to climb on because they are empty inside and built over that hole in the ice. Although some frozen volcanoes were discovered a few years ago, it is still rare to witness one.
Ice volcanoes typically form near large bodies of water where freezing temperatures below allow an ice shelf to form over the water’s surface along the coastline. Meanwhile, waves beneath the shelf must be strong enough to crack the ice and push water out. For this reason, ice volcanoes tend to form along shorelines where winds blow up waves constantly.
For example, when the Oval Beach volcanoes were spotted, the wind was almost due west, which was perfect for pushing waves right into the shoreline at this location. Due to their superior size, the Great Lakes may be more likely to form ice volcanoes along their shores than smaller lakes.
So if you want to see an ice volcano in person, the Great Lakes may be your best choice—but be cautious where you step!

While most people have the idea that volcano eruptions are one of the most destructive disasters in nature , seeing a volcano erupt is a wonderful experience, and you can really feel the heat by climbing to the summit of Pacaya for a close-up view.
There are guided tours every day up this highly active volcano from Antigua, giving travelers a chance to see Mother Nature at her most powerful.Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won’t miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2,560 meters high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb you hear the dull sounds of eruptions high above. Steaming, hot remains from recent eruptions begin to line the path as you near the active summit: the Mckenney Cone (火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the relative safety of the old, inactive summit.
Many tours are timed so that you arrive at the cone of the volcano in plenty of time for sunset and the full contrast between the erupting red lava(岩浆) and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot steams up to 100 meters into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night, the burning lava quietly falls down the side of the volcano. For you, too, it is time to get down.
1.Antigua is a city .
A. that gives a close-up view of Pacaya
B. that is famous for its tour agencies
C. where the exciting Pacaya tour starts
D. where people can enjoy cultural festivals
2.The word “summit” appears several times in the passage. It means___.
A. cooled rocks along the path

3.Many tours are timed for people to .
A. get down the mountain in time when night falls

D. appreciate the scenery of the Pacaya mountain

Where we live，on the eastern shore of Maryland，the gentle waters run in and out like fingers slimming at the tips.
The Canada geese know this place，as do the white swans and the ducks. In autumn，they come home for the winter. Once or twice each year，snow and frozen rain move into the area. When this happens，if the river is at its narrowest，there is a freeze which hardens the water to ice.
One morning，a friend of mine set the breakfast table beside the huge window，which overlooked the Tred Avon River. Suddenly she leaned forward and cried out，“There is a goose out there.”
We saw the figure of a large Canada goose，very still，its wings folded tight to its sides，its feet frozen into the ice.
Then from the dark skies，she saw a line of swans. They floated from the top of the sky downward and at last landed on the ice. My friend was on her feet now，with one hand against her mouth，unbelieving. As the swans surrounded the frozen goose，she feared that life it still had might be pecked(啄) out by those great swan bills.
Instead，those bills began to work on the ice. The long necks were lifted and curved down，again and again. It went on for a long time. At last，the goose’s head was lifted. Its body was pulled. Then the goose was free and stood on the ice. And the swans stood in the air watching. Then，as if it had cried，“I cannot fly.” Four of the swans came down around it. Their powerful beaks chipped off the ice held in the feathers. Slowly，the goose spread its wings as far as they would go，and moved slowly into the sky.
This is a true story. I just think of it in the bad moment，and from it comes only one hopeful question：If so for birds，why not for man？
1.Which would be the best title for the passage?
A．Why Not for Man? B．Graceful Swans
C．Swans’ Brave Act D．I Just Couldn’t Believe It!
2.What happened to the Canada goose?
A．It was deserted by other geese.
B．It was stuck in the ice.
C．It was wounded and couldn’t fly.
D．It was lost in the water.
3.At first the author’s friend was worried that________.
A．the swans would not help the Canada goose
B．she didn’t care about this matter any more
C．the swans wouldn’t identify with the Canada goose
D．the swans would peck the Canada goose to death
4.What did the swans do when they saw the Canada goose couldn’t fly?
A．They chipped off the ice held in its feathers.
B．They waited patiently for the ice held in its feathers to melt.
C．They came down and lifted it up to the sky together.
D．They stayed with it and protected it.

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 underwater quake and occurred in the Indian Ocean. This caused a huge tsunami （海啸）to cross the Indian Ocean. It destroyed coastlines and communities and brought death and destruction to many people. The survivors needed fresh water, food and shelter as well as medical help. People from all over the world gave money.
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 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 （小行星）impacts （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（恐龙）. Disasters on the Earth may seem dangerous, but the biggest threat to humans is likely to come from space.
1.What did the world do when the tsunami occurred in the Indian Ocean?
A.They gave away money to the beggars.
B.They sponsored to help the people survive.
C.They donated their possessions to the survivors.
D.They helped rebuild the coastlines and communities.
2.What can scientists predict about earthquakes?
A.The possible time. B.The possible climate.
C.The possible place. D.The possible frequence.
3.Which is the best heading that matches Paragraph 3?
A.What do earthquakes destroy? B.Why do earthquakes happen?
C.How can we prevent earthquakes? D.Which is the most dangerous natural disaster?
4.Where does the author think the most dangerous natural disaster will come from?
A.Space. B.Earth. C.Humans. D.Wild animals.
