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(回收車)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(廢渣埋填池) “,Reid said.
Dog waste will be poured into a methane digester(沼氣池),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.

Put an ice cube from your fridge into a glass of water. You have a piece of string(線) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers.
You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.
First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze again. After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don’t put enough salt, the water will freeze again.

Attending a university is an important part of a person’s life. Today, many people go to a university to study and train for a future job in subjects like law, medicine, or education. But the university is not a modern invention. It has a history that is over a thousand years old.
The world’s oldest university, Al-Azhar, is in Cairo, Egypt. It was first built as a mosque in A.D. 972. A few years later, learners and teachers began meeting in the mosque in “tutoring circles”. They read and talked about the subject of law. Around 988, leaders in the city of Cairo decided to create a school for higher learning and the University of Al-Azhar was founded.
At Al-Azhar, there were many university ‘firsts.’ Courses were created. The earliest ones taught at Al-Azhar were in law and religion. In a course, students read and studied with the teacher, but there was also free discussion. Often, students and teachers talked about a topic, and there was no ‘right’ answer. Finally, scholars from around the world came to Al-Azhar to teach and do research. At the university, people studied the past, but it was also a place for sharing new ideas.
Over a thousand years later, Al-Azhar is still an important university in the world. Its library contains more than 250,000 of the world’s oldest and most valuable books. Today, many of the world’s most important universities such as Oxford and Harvard still follow the traditions started at Al-Azhar.

Michael Newman is trying to get ahead to provide for his family. He is a talented architect who willingly takes on projects with impossible deadlines in order to please his boss Ammer and secure a partnership in the firm. But all work and no play mean that Michael is missing spending time with the family. His wife Donna is trying to be available for swim meets, camping trips, tree house completion and some good old days. Ben and Samantha are his adoring children who just want to play with their dad.
After yet another long day filled with frustrations, Michael goes in search of a universal remote (萬能遙控器) so that he can at least be in control of his TV. Only one store is open: Bed, Bath and Beyond – where he gets a very special universal remote.
There is a lot of power in Michael’s new toy; he can revisit old scenes from his past, put people on mute (無聲的) and fast forward through the boring parts. He turns off the volume each time he argues with his wife. He fast – forwards through a boring family dinner. He skips ahead to avoid a bad cold. He jumps to the chapter where he gets a promotion. It’s all really great until the remote begins to use some of the specially programmed features – the remote starts predicting when Michael will use it, automatically hurtling (猛扔) him beyond life’s difficult and mundane moments. But most of our lives are difficult and mundane, so Michael is forced to travel years into the future. Eventually, he realizes the family dog has died and been replaced by another, that his kids have grown up, that his wife is married to someone else, and that he weighs 400 pounds.

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(植物學(xué)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 at 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(對(duì)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 light.
    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.

  “Helping survivors (生還者) of the earthquake and killer waves in the Indian Ocean last week is a race against time” says Kofi Annan , the United Nations secretary-general .
The concern about offers of international aid is based on history. Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our aim to give and receive support from one another under stressful surroundings. Social support consists of the exchange of resources among people based on their interpersonal ties.
Those of us with strong support systems appear betterable to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over a range of illnesses, from depression to heart disease, show that the presence of social support helps people prevent illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways. First, friends, relatives, and co-workers may let us know that they value us. Our self-respect is strengthened when we are popular with others despite our faults and difficulties. Second, other people often provide us with informational support. They help us to notice and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Engaging in leisure-time activities with others helps us to meet our social needs while at the same time distracting(轉(zhuǎn)移...注意力)us from our worries and troubles. Finally, other people may give us instrumental support: a financial aid, material resources, and needed services -- that reduces stress by helping us deal with our problems.
59. Research shows that people's physical and mental health _______.
A. depends on the social welfare (福利)systems which support them
B. has much to do with the amount of support they get from others
C. depends on their ability to deal with daily worries and troubles
D. is closely related to their strength for dealing with major changes in their lives
60. The underlined word" cushions" in Para.3 means _______.
A. adds up to                                  B. does away with
C. reduce the effect of                 D. depends on
61. Helping a sick neighbor with some repair work is an example of _______.
A. instrumental support                     B. informational support
C. social companionship             D. the strengthening of self-respect
62. Social companionship is very important because _______.
A. it helps strengthen our ties with relatives
B. it enables us to get rid of our faults and mistakes
C. it makes our leisure-time activities more enjoyable
D. it draws our attention away from our worries and troubles

In a surprising discovery about where higher life can survive, scientists have found a shrimp —— like creature and a jellyfish swimming beneath an Antarctic ice sheet.
About 180 meters below the ice where no light can get through, scientists had thought nothing much more than a few microbes (微生物) could exist.
That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp – like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (觸須) they believe came from a jellyfish.
“We were operating on the presumption that nothing’s there.” Said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy having on your plate.”
“We were just gaga (狂熱的) over it,” he said of the 7.5cm long, orange creature starring in their two – minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod, which is distantly related to the shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists thinking that if shrimp – like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?
Cynan Ellis – Evans, a scientist of the British Antarctic Survey called the finding fascinating. He said it was possible the creatures swam in from far away and don’t live there permanently.
But Kim, who is a co-author of the study, doubts it. “The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20 cm – wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small of an area,” she said.
Yet scientist were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t, Kim said.
“So how do they survive? That’s the key question.” Kim Sai.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.
小題1: What does the underlined word “harsh” probably mean?
A.coldB.loudC.cruelD.ugly
小題2:According to Kim, the shrimp – like creature        .
A.swam great distances to AntarcticB.has always lived in the region
C.gradually evolved from shrimpsD.has nothing in common with shrimps
小題3:The finding is significant in that           .
A.it marks NASA’S first Antarctic biological study
B.it proves there is marine life in the Antarctic
C.it could inspire further study of life in harsh environments
D.it shows that Lyssianasid amphipod is closely related to shrimps
小題4:Which of the following statements about the discovery is FALSE?
A.Complex life usually lives on other forms of life.
B.Scientists saw two creatures in the two – minute video.
C.It is possible for creatures to live 180 meters below the ice though there is no light.
D.Scientists captured the shrimp – like creature in a camera by drilling a hole through the ice.

    AThe three main types of secondary education in the United States have been provided by the Latin grammar school, the academy, and the public high school. The first of these was a colonial institution. It began in New England with the establishment in 1635 of the Boston Free Latin School. The curriculum(課程) consisted mainly of the classical languages, and the purpose of this kind of school was the preparation of boys for college, where most of them would be fitted for the ministry.?
The academy began in the early 1750’s with Benjamin Franklin’s school in Philadelphia, which later became the University of Pennsylvania. It extended generally to about the middle nineteenth century, except in the southern states where the public high school was late in developing and where the academy continued to be a principal means of secondary education even after 1900.The academy was open to girls as well as to boys, and it provided a wider curriculum than what the Latin grammar school had furnished. It was designed not only as a preparation for college but also for practical life in commercial and business activities. Although its wide educational values are evident and are recognized as important contributions to secondary education in this country, the academy has never been considered a public institution as the public high school has come to be.?
The public high school had its origin in Massachusetts in 1821 when the English Classical School was established in Boston. In 1827,the state enacted(制定)the first state wide public high school law in the United States. By 1840,there were perhaps a dozen public high schools in Massachusetts and many in other eastern states by 1850,they could also be found in many other states. Just as the curriculum of the academy grew out of that of the Latin grammar school, the curriculum of the public high school developed out of that of the academy. The public high school in the United States is a repudiation(推翻) of the aristocratic(貴族的)and selective principle of the European educational tradition. Since 1890,enrollments( 入學(xué))in secondary schools, mainly public high schools, have practically doubled in this country every ten years.
56.According to the passage, which of the following sequences indicates the order in which the schools developed?
A.Latin grammar school, public high school, academy.
B.Latin grammar school, academy, public high school.
C.Public high school, Latin grammar school, academy.
D.Public high school, academy, Latin grammar school.
57.It is the opinion of the author that the academy, compared with the public high school, was ____.
A.obviously academically better
B.more discriminatory in student selection
C.coeducational
D.not generally considered as a public institution
58.One can probably infer from his article that “Latin grammar school” refers to ____.
A.the Boston Free Latin School
B.a(chǎn)ll the elementary schools in the United States
C.schools which taught Latin, exclusive of all other subjects
D.a(chǎn) number of schools which developed in New England
59.It is implied but not stated in the passage that ____.
A.European educational systems are not good
B.As high schools developed in the united states, the decision was made to make them responsible to people from all classes of society.
C.There was an aristocratic and selective principle in the European educational tradition
D.public high schools in the United States embraced the European educational tradition
