San Francisco, a leader in urban recycling, is preparing to turn dog waste into energy.
Norcal Waste System Inc., the city’s largest garbage company, plans to test collection carts(回收车)and collection bags in a city-center park which is popular with dog walkers.
A city study found that almost 4 percent of all the garbage picked up at San Francisco homes was from animal waste, Norcal Waste spokesman Robert Reid said. San Francisco has about 120,000 dogs.
“The city asked us to start a program to recycle dog waste in order to cut back adding more waste in landfills(废渣埋填池) “,Reid said.
Dog waste will be poured into a methane digester(沼气池),and the methane it gives off will be collected and burned to make electricity or to heat homes.
“Dogs and cats in the United States produce about 10 million tons of waste a year,” Will Brinton, an environmental scientist said.
“As much as we love them, our pets leave a lot of fertilizer behind them in yards and on the street but that can be a major source of contamination of groundwater,” Brinton said.
European cities such as Zurich, Frankfurt, Munich and Vienna are starting biology programs to turn waste into gas ,he said.
San Francisco runs a great program to recycle bottles, cars, paper and other rubbish and now two-thirds of its garbage needn’t be carried to landfills .The city’s goal is a 75 percent drop by 2010 and zero new waste in landfills by 2020.

The ocean contains many strange and surprising creatures. One such creature is the puffer fish. This very strange fish is probably the most poisonous creature in the ocean. The poison that this fish produces is 275 times more poisonous than the chemical which is usually used to kill rats.
The puffer fish gets its name from the way the fish protects itself from enemies. Whenever it is attacked, the fish blows up its body to three times bigger than its normal size!
Another strange thing about this fish is the fact that it can swim like other fish. Because it does not have bones like oth

er fish, the puffer fish can only move slowly through the water as it is carried by waves.
The puffer fish also has funny teeth. These teeth stick out of the fish’s mouth and are used by the fish to open the shells of the creatures that live on the ocean floor.
This strange, ugly, and very poisonous fish is actually a very expensive kind of food in Japan. The Japanese call this fish “fugu”, and people have been known to pay $150 per person to eat a fugu meal (usually eight servings)!
Very brave people want to eat the most poisonous part of the fugu fish on purpose. They think that this part of the fish tastes the best! Strict laws have been passed to control restaurants which serve fugu; however, quite a few people have still died from eating fugu.Almost 200 people have died over the past 25 years.
When people eat fugu poison, they do not die on the spot. First, they feel a strange tickle on their lips and in their mouth. Then they can not feel anything with their fingers. Finally, they cannot move or speak. Death follows when they can no longer breathe. The poison may take only a few minutes or up to six hours to kill a person. There is no known cure for fugu poisoning.

Heavy snow blanketed Anhui and Hubei provinces yesterday, cutting off power to some villages and blocking roads. Meanwhile, more snow is expected to cover the south in the coming three days.
Meteorologists said that the snow, which started Sunday night, is expected to fall throughout the south until this Friday, with temperatures falling below zero. The precipitation is expected to help relieve the severe drought conditions.
The temperature in the north will rise after this Friday and the south will be warmer after Nov 22nd, forecasters predicted yesterday.
The national meteorological watchdog issued an orange alert-the second—highest level-for snowstorms yesterday morning, warning that snowfalls in some areas will reach 20 mm at most.
Snowstorms refer to snowfalls that reach 10 mm in 24 hours. Snowfalls below 10 mm and above 5 mm are called heavy snows.
Last Friday, officials from the Hubei provincial government asked the transportation department, the meteorological bureau and related departments be fully prepared for the coming snow, with an emergency team ready to provide around-the-clock assistance.
The predicted snow in the south did not bring much trouble to air and rail travel with advance preparation.
The provincial education bureau declared an emergency plan on Sunday, asking primary and high schools to close when the snowstorms become severe.
The 16 expressways in snow-hit places in Hubei were scattered with 42.8 tons of snow-melting agents and about 4.580 sqm of anti-slip fabric. The latest information from the provincial expressway administration yesterday showed that traffic flowed smoothly during the snow.
The Tianhe Airport in Wuhan, Hubei province, had seven snow-melting vehicles working to ensure timely take-offs and landings.
The Anhui meteorological bureau declared all emergency alert because of the snowstorm on Sunday, with 43 cities and counties issuing alerts for snows and two issuing alerts for frozen roads. Shucheng county and Huoshan county issued time top alert because of the snowstorms on Sunday.
Luogang airport in Hefei, Anhui Province, was shut down for four hours since 7 a.m. yesterday due to the heavy snow, Xinhua reported.
The snow caused time rush-hour traffic to be heavily congested and many commuters left home earlier than usual in the morning.
Ye Wei, a worker at Hefei University of Technology, said his ride to work took a half-hour more than usual.
“Maybe tomorrow I will have to get up one hour earlier than before, because of the frozen roads,” Ye said.
The heavy snow first hit northern China, claiming dozens of lives, causing hundreds of injuries, paralyzing the traffic and grounding hundreds of flights.
The whiteout that began Nov 9th has killed at least 32 people and affected more than 9.6 million in seven provinces. More than 15,000 buildings have collapsed and nearly 300, 000 hectares of farmland have been destroyed, Ministry of Civil Affairs officials said on Sunday.
The snowfall was the heaviest in the past six decades in some northern and central provinces like Hebei, Shanxi, Shaanxi and Henan, with an economic loss reaching 7 billion yuan（$ 1.02 billion）, ministry officials said.

We may all have had the embarrassing moment: Getting half-way through a story only to realize that we’ve told this exact tale before, to the same person. Why do we make such memory mistakes?
According to research published in Psychological Science, it may have to do with the way our brains process different types of memory.
Researchers Nigel Gopie, of the Rotman Research Institute in Toronto, and Colin Macleod, of the University of Waterloo, divided memory into two kinds. The first was source memory, or the ability to keep track of where information is coming from. The second was destination memory, or the ability to recall who we have given information to.
They found that source memory functions better than destination memory, in part because of the direction in which that information is travelling.
To study the differences between source and destination memory, the researchers did an experiment on 60 university students, according to a New York Times report. The students were asked to associate (联想) 50 random ( 随意的) facts with the faces of 50 famous people. Half of the students "told" each fact to one of the faces, reading it aloud when the celebrity"s (名人的) picture appeared on a computer screen. The other half read each fact silently and saw a different celebrity picture afterward.
When later asked to recall which facts went with which faces, the students who were giving information out (destination memory) scored about 16 percent lower on memory performance compared with the students receiving information (source memory).
The researchers concluded that out-going information was less associated with its environmental context （背景）---- that is, the person ---- than was incoming information.
This makes sense given what is known about attention. A person who is giving information, even little facts, will devote some mental resources to thinking about what is being said. Because our attention is limited, we give less attention to the person we are giving information to.
After a second experiment with another group of 40 students, the researchers concluded that self-focus is another factor that undermines destination memory.
They asked half the students to continue giving out random information, while the other told things about themselves. This time around, those who were talking about themselves did 15 percent worse than those giving random information.
"When you start telling these personal facts compared with non-self facts, suddenly destination memory goes down more, suggesting that it is the self-focus component ( 成分) that"s reducing the memory, Gopie told Live Science.
72. The point of this article is to ____.
A. give advice on how to improve memory
B. say what causes the memory to worsen
C. explain why we repeat stories to those we"ve already told them to
D. discuss the differences between source and destination memory
73. What can we learn from the article?
A. Source memory helps us remember who we have told the information to.
B. One"s limited attention is one of the reasons why those reading aloud to the celebrity"s pictures perform worse on the memory test.
C. Silent reading is a better way to remember information than reading aloud.
D. It tends to be more difficult for people to link incoming information with its environmental context than outgoing information.
74. The underlined word "undermines" probably means ____.
A. weakens B. benefits C. explains D. supports
75. What did the scientists conclude from the second experiment?
A. Destination memory is weaker than source memory.
B. Focusing attention on oneself leads to relatively poor source memory performance.
C. Associating personal experience with information helps people memorize better.
D. Self-focus is responsible for giving information twice or more to the same person.

The Royal Horticultural Society(RHS) finds that women gardeners’ voices speed up the growth of tomato plants much more than men’s.
In an experiment, the researchers found that tomato plants grew up to two inches taller if they were sung to by a female rather than a male.
The most effective voice came from Sarah Darwin, whose great-great grandfather was the botanist(植物学家) Charles Darwin, one of the founding fathers of the RHS.
She read a passage from the On the Origin of Species and beat nine other ‘voices’. Her plant grew nearly two inches taller than the best performing male and half an inch higher than her nearest competitor.
Colin Crosbie, Garden Manager a

t the RHS, said, “We predicted that the male voice would be more effective but it turned out that the ladies’ voice was far better than the gentlemen’s. We just don’t know why. It could be because they have a greater range of pitch(高音) and tone(音色) that affects the sound waves that hit the plant.The sound wave is on environmental effect just like rain or light.”
In the experiment, every plant was played a different voice through earphones connected to the plant pot, and the environmental conditions for all the plants remained the same throughout the experiment. To ensure that the results of the experiment were convincing, two plants were also left to grow in silence.
The results showed that women on average saw their plants grow an inch taller than their male counterparts(对手) and much more than the plants left in complete silence.
Miss Darwin said, “I’m not sure if it’s my sweet tones or the text that I read from On the Origin of Species that made the plant sit up and listen, but either way, I think it is an honor to have such a voice, and it is especially fitting for me, because for years I have been studying wild tomatoes at the Natural History Museum(NHM) in London.”
　60. How many tomato plants were chosen for this experiment?
　　 A. 9.　　　　 B. 10. C. 11.　　 D.12.
　61. What can we learn about Sarah Darwin?
　　 A.She is very proud of her sweet voice..
B. She is one of the founding fathers of the RHS.
　　 C. She has discovered why her voice benefits plants.
　　 D. She will work at the NHM in London after the experiment.
　62. Why were two plants left to grow in silence in the experiment?
　　 A. To make the results of the experiment trustworthy.
　　 B. To convince people that sound waves are better than rain and lig

ht.
　　 C. To help find out how many inches plants can grow with the help of voices.
　 D. To prove that the environmental conditions for the plants remained the same.
　63. What can be inferred from the passage?
　　 A. The text from On the Origin of Species can help plants grow..　　　　
　　 B. Sarah’s nearest competitor was also a woman..
　　 C.Men’s voices have a greater range of pitch and tone than women’s..
　　 D.Colin Crosbie predicted that women’s voices were better for the plant than men’s.
