In a mountainous area of Brazil， there is a kind of beautiful butterfly which can kill men. If people meet them， they will come down in great quantities to bite and kill， sucking （吸） blood and eating flesh through the wounds they cause.

In June， 1966， a boy named Marl Andre who went into the mountains in search of butterfly specimens （標本） was killed by these butterflies. A country boy saw him as he was just about to raise his net to catch a butterfly. Suddenly thousands of butterflies came down upon him， covering him all over. The boy struggled and cried as he tried to free himself from their attack. Finally he fell senseless to the ground. Police examined his body and proved that he had died of bites by butterflies.

In New Guinea， there is a kind of needlefish which also kills men. Because it likes light at night， it will swim near the lights of fishing boats， then suddenly shoot out of water like an arrow to its target， and force its 3-inch sharp mouth into a human body. Often people are thrust （戳） in the eye， or through the chest or stomach， resulting in death. Sometimes it will even attack the people in a fishing boat in broad daylight.

About 10 persons in the world are killed by sharks every year， yet more than 20 are killed by needlefish every month.

1. Marl Andre was killed when he ___ .

A. raised a net B. went to Brazil

3. According to the story， each year needlefish kills men ___ .

A. fewer than sharks do

B. twice more than sharks do

C. 24 times more than sharks do

D. about 10 more than sharks do

4. Whats the best title of the passage？

A. Animal Killers

B. New Guinea—Not Fit to Live In

Against the supposition that forest fires in Alaska， Canada and Siberia warm the climate， scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past ten years. Scientists predict that with climate warming， fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming， while heat mirrored back into space tends to cause cooling.

This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus catch heat.

Scientists found that right after the fire， large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone （臭氧） levels increased， and ash from the fire fell on far-off sea ice， darkening the surface and causing more radiation （輻射） from the sun to be taken in. The following spring， however， the land within the area of the fire was brighter than before the fire， because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space， leading to cooling.

“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire， and found a measurement closely related to the global air temperature. Typically， fire in northern regions occurs in the same area every 80 to 150 years. Scientists， however， found that when fire occurs more frequently， more radiation is lost from the earth and leads to cooling results. Specifically， they determined when fire returns 20 years earlier than predicated， 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases， but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is got or lost from the earth.

5. According to the new findings， What may taking steps to prevent northern forest fires may do？

A. Result in a warming climate.

B. Lead to a longer fire season.

C. Protect the forests and the environment there.

D. Cause the forest fires to occur more frequently.

6. Earlier studies about northern forest fires ____.

A. indicate that forest fires will pollute the atmosphere

B. suggest that the fires will speed up climate warming

C. analyze all aspects of how northern fires influence climate

D. suggest that people should take measures to protect environment

7. What does the underlined phrase “soaked up” probably mean？

A. Released. B. Absorbed.

C. Created. D. Distributed.

8. From the passage what may forest fires do in Alaska， Canada and Siberia？

A. Warm the climate as the supposition goes.

B. Help to get more energy rather than release more energy.

C. Destroy large areas of forests and pollute the far-off sea ice.

D. Allow more snow to mirror more sunlight into space and thus cool the climate.

Roller skating is easy and fun， and today it is popular throughout the world. People roller skate outside on paths and roads， and inside in rinks. But a long time ago， it wasnt easy at all. Before 1750， the idea of skating didnt exist. That changed because of a man named Joseph Merlin. Merlins work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man full of ideas and dreams. People called him a dreamer.

One day Merlin received an invitation to attend a fancy dress ball （化裝舞會）. He was very pleased and a little excited. As the day of the party came near， Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.

Merlin tried different ways but only to make himself fool. Finally， he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.

On the night of the party Merlin rolled into the room playing his violin. Everyone was surprised to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly， he ran into a huge mirror that was hanging on the wall. Down fell the mirror， breaking into pieces. Nobody forgot Merlins grand entrance for a long time！

9. Why did people think that Merlin was a dreamer？

A. He often made surprises.

B. He was a gifted musician.

C. He invented the roller skates.

D. He was full of imagination.

10. Merlin put wheels under his shoes to ____.

A. test his invention

B. arrive at the party sooner

C. draw the guests attention

D. show his skill in walking on wheels

11. What is the main point of the last paragraph？

A. Merlin got himself into trouble.

B. Merlin succeeded beyond expectation.

C. The party guests took Merlin for a fool.

D. The roller skates needed further improvement.

12. The text is mainly about ____.

A. a strange man

B. an unusual party

C. how roller skating began

D. how people enjoyed themselves in the 18th century

Dear Wang Yang，

Thanks for your nice letter！

After I had spent a month with my English family， I slowly began to understand their English a little better. 1 Students in my group are from different cities of Britain and their dialects are different too！ Some of their accents are quite strong and they also have their own words and expressions.

2 Before I came to England I had thought that fish and chips were eaten every day. Thats quite wrong！ I get rather annoyed now when I hear all the foolish words about typical English food.

I had expected to see “London fog”. 3 We had no idea that most of this “thick fog” disappeared many years ago when people stopped using coal in their homes. But the idea to speak about weather was very helpful. 4 So are habits. People tell me what is typical British here in London is not always typical in Wales or Scotland. Local habits and traditions are not the same as what we knew.

5 Probably Britain has more living signs of its past than many other countries. And people have always been proud of having ancient buildings in capitals， big cities and the countryside.

I will tell you more about Britain in my other letters.

Love from Britain，

Li Xia

traditions.
