Do you like to eat out? Do you like to eat quickly? Do you like inexpensive food? Some people go to fast-food restaurants for these reasons. In the past, people usually went to diners(小餐館)for these reasons. In fact, many people in the States still go to diners today for the same reasons.
A man named Walter Scott had the first “diner” in 1872. It wasn’t a real diner. It was only a food cart. People on the street walked up to the cart to buy food. These carts served late-night workers who wanted a cup of coffee and a late-night meal. The meal was a sandwich or boiled eggs. In 1887, Samuel Jones built the first diner big enough to allow the customers to come inside. However, they did not sit down. Later, people built diners with counters and stools, and people sat down while they ate.
Before long, many diners stayed open around the clock. In other words, people were able to eat in diner at any time. Diners changed in other ways, too. The original menu of sandwiches and coffee became bigger. It included soup, favorite dishes, and a breakfast menu. In addition, diners soon became permanent buildings. They were no longer carts on wheels.
Diners today look similar to  the diners of the early 1900s. They are usually buildings with large windows. Inside, the diners have shining counters with stools, booths, and tables and chairs. People can eat all three meals in a modern diner.
Today, many people eat in fast-food restaurants such as McDonald’s and Burger King. However, the diner remains an American tradition, and thousands of people still enjoy eating there. It was popular a century ago, and it is still popular today.
1.A man named Walter Scott had the first “diner” in 1872. Why is the word “diner” in quotation marks(引號(hào))?
A.Because it is spelled differently from “ dinner”
B.Because the first diner was not what it is now
C.Because diner was a new word
D.Because it is a special kind of restaurant
2.What meals did the first diners serve?
A. only breakfast    B. Only lunch   C. Only night-meals  D. All of the above
3.According to paragraph 3, diners changed in __________
A. Two ways      B. three ways     C. four ways       D. five ways
4.Which of the following is NOT true according to the passage?
A.Diners existed before a fast-food restaurant
B.The menu included more food than sandwiches and coffee
C.Burger King is a fast-food restaurant
D.Sandwiches became bigger
5.The main idea of the passage is that ______________.
A. The diner is a traditional , popular place to eat in the United States
B.Samuel Johns built the first diner big enough to allow the customers to come inside
C.American diners serve many types of food 24 hours a day to their customers

Obesity(肥胖) in children and adolescents is rising at an alarming rate. Currently over 15% of young people over 6 years old are obese, and obesity is also increasing among children aged 5 and younger.
Children are considered to be overweight if the BMI(Body Mass Index) is over 85% of the weight group in their age and sex categories. If it is 95% and over, they are considered to be obese. Adolescents are generally judged according to adult criteria(標(biāo)準(zhǔn)) for obesity, although there are other considerations in this population, for many factors will affect the result of these measurements.
Causes and Risk Factors for Obesity in Children
Lifestyle Factors. Without educational or parental guidance, children are extremely greatly exposed to the cultural pressures that are largely responsible for growth of the obesity. Neither the media nor the educational system has strong programs that encourage healthy way of life, including exercise and healthy foods. The following are some specific problems created by the culture:
﹡Too much television watching plays an important role in obesity in children. Not only is it a passive activity, but television also offers countless temptations(誘惑) with its advertisements for fast foods, sugar cereals, and unhealthy snacks. In one study obesity rate were lowest in children who watched television one hour or less a day and highest in those who watched four or more hours.
﹡Sugar, particularly from soda, other sweet drinks, and fruit juice, may be major contributors to childhood obesity. One study reported that drinking soda regularly increases a child’s risk for obesity by 60%.
﹡Less physical exercise and greater sitting activities play another significant role in obesity in children. A high level of physical activity – not just using up energy – is important for weight control in young people.
Family History. Parental obesity more than doubles the risk that a young child, whether thin or overweight, will become obese as an adult. In older children and teenagers, obesity in parents starts to affect less as a predictor(預(yù)言) for body weight than their own weight. The risk may be due to environmental or genetic factors, or both.
Ethnic and Socioeconomic Factors. As in adult populations, children from lower socioeconomic groups and minority populations are at higher risk for obesity. For example, among young Mexican Americans and African Americans, there has been an increase in overweight trend of about 13% to over 23%.
69.What’s the main idea of the passage? ______________.
A. The trend of obesity                B. Causes of obesity
C. Fight against obesity                D. Obesity in children
70.How many main factors leading to obesity in children are mentioned?
A. 2              B. 3                C. 4                 D. 5
71.According to the passage, which of the following children is most likely to be obese?
A. A 5-year-old child whose parents are overweight.
B. A 16-year-old teenager whose parents are obese.
C. A child who watches TV one hour per day.
D. A child who take regular exercise.
72.Which of the following is NOT true?
A. Parents should give some guidance on healthy lifestyles.
B. Watching TV four hours a day will surely lead to obesity in children.
C. Children from minority populations are more likely to be obese.
D. Children should take more physical exercises.

A strange thing happens to nearly everybody at night. They turn off the lights, put up the covers and close their eyes. Six or seven hours later, they wake up again. Strange, isn’t it?
Sleep puzzles science. Scientists and doctors would rather talk about why one can’t fall asleep. They are not so sure what causes sleep.
The best conditions for sleep, they say, are good health and meal neither too big nor too small. No worries and a comfortable place to sleep in are important, too. They advise against two in one bed.
Strange things happen during sleep. For example, you move often. You would feel tired if you didn’t. You also dream. Part of your brain is still awake when you dream. Dreaming happens when the memory and imagination parts of your brain are still awake. Experiments have shown that bad dreams may be caused by a stomachache.
Don’t worry if you dream. Some great stories and poems were begun while the writers slept.

Each year, road accidents kill a million people and injure millions more . The economic costs are greatest for developing countries . Earlier this year , the United Nations called for a campaign to improve road safety .
One way to avoid accidents is better driving . Another is better roads and bridges . Engineers in the Unites States have designed ten new concrete mixtures that they think could make bridges last longer .
Professor Paul Tikalsky leads the experiments by a team at Pennsylvania State University . He says bridges made of concrete now last about twenty-five to thirty-five years . But he says the new mixtures might extend that to seventy –five or even one-hundred years .
Concrete is made of stone , sand , water and cement(水泥). The materials in the cement hold the concrete together . Ancient Romans built with concrete . Yet strengthened concrete bridges did not appear until the late 1800s . People keep looking for new ways to improve concrete . Professor Tikalsky says it is one of the most complex of all chemical systems .
The new mixtures designed by his team contain industrial waste products . He says these make the concrete better able to resist damage from water and salt over time . One of the products is fly ash . This is released into the air as pollution when coal is burned .
Professor Tikalsky says particles (顆粒)of fly ash are almost exactly the same size and chemical structure as Portland cement . This is the most costly material in concrete . So using fly ash to replace some of it would save money .
The federal government is paying for part of the research . Engineers anywhere can use the technology . Professor Tikalsky says some of the ideas have already been put to use in China , the Philippines and other countries .
小題1:Why did the United Nations launch the campaign ?
A.Because the United Nations wanted to reduce road accidents and economic costs
B.Because two million people were killed in the accidents .
C.Because engineers wanted to design ten new concrete mixtures .
D.Because the United Nations made bridges of the new mixtures which could last for about 20 to 35
years .
小題2:What does the underlined word “ this ” in the sixth paragraph refer to ?
A.Fly ashB.Portland cementC.SandD.Chemical
小題3:Which of the following statements is TRUE ?
A.Ten new concrete bridges have already been built in the United States .
B.A new concrete bridge could last 50 more years than an ordinary concrete one .
C.People didn’t know how to build with cement until the late 1800s .
D.Water and salt won’t do any damage to bridges over time .

The first breath-taking pictures of the Earth taken from space showed it as a solid ball covered by brown land masses and blue-green oceans. We had never seen the Earth from that distance before. To us, it appeared as though the Earth had always looked that way and always would. Scientists now know, however, that the surface of the Earth is not as permanent as we had thought.
Scientists explain that the surface of our planet is always moving. Continents moves about the Earth like huge ships at sea. They float on pieces of the Earth’s outer skin. New outer skin is created as melted rock pushed up from below the ocean floor. Old outer skin is destroyed as it rolls down into the hot area and melts again.
Only since the 1960s have scientists really began to understand that the planet Earth is a great living machine. Some experts have said this new understanding is one of the most important revolutions in scientific thought. The revolution is based on the work of scientists who study the movement of the continents—a science called plate tectonics.
The modern story of plate tectonics begins with the German scientist Alfred Wegener. Before World War One, Wegener argued that the continents had moved and were still moving. He said the idea first occurred to him when he observed that the coastlines of South America and Africa could fit together like two pieces of a puzzle. He proposed that the two continents might have been one and then split apart.
Wegener was not the first person to wonder about the shape of the continents. About 500 years ago, explorers thought about it when they made the first maps of Americas. The explorers noted the east coast of North America and South America would fit almost exactly into the west coast of Europe and South Africa. What the explorers did not do, but Wegener did, was to investigate the idea that the continents move.
1. What does the writer mainly tell us in the passage?
A. The first breath-taking pictures of the Earth taken from space.
B. Human’s recognition of the earth’s surface.
C. The German scientist Alfred Wegener.
D. The early explorers’ discovery.
2. Which of the following is true according to the passage?
A. We didn’t see the Earth from far away until we saw the picture taken in the space.
B. Our ancient thought that the surface of the earth is still.
C. Alfred Wegener was not the first person to investigate the idea that the continents move.
D. The coastline of India and Africa fit together.
3. The last word of the third paragraph “tectonics” mean “________”.
A. study of construction
B. study of architecture
C. earth surface
D. structural geology
4. What did the explorers find?
A. The coastlines of South America and Africa could fit together.
B. The coastlines of North America and Africa could fit together.
C. The east coastlines of North America and the west coast of Europe could fit together.
D.The coastlines of North America and India could fit together.

The need to feed a growing population is putting much pressure on the world’s supply of water. With 97% of the world’s water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage(短缺)seems strange to someone fortunate enough to live in a high rainfull country, many of the world’s agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seaons, the costs of water redistribution(重新分配)are very high. Notonly is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water many flow easily through pipes to fields,but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling ro countries with agricultural industries in areas dependent on irrigation(灌溉). In Texas, farmers’ overuse of irrigation water be resulted in a 25% redcution of the water stores. In the Central Valley area of south eastern USA, a huge water engineering project provided water for farming in dry vallege, but much of the water use has been poorly managed.
Saudi Arabia’s attempts to grow wheat in desert areas have been the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.
1. From the first two paragraphs we learnt that _______.
A.much of the world’s water is available for use
B.people in high rainfll countries feel lucky
C.the costs of water redistribution should be considered
D.water can be easily carried through pipes across the world
2.Which of the following is true?
A.The water  in Texas have been reduced by 75%.
B.Most industries in the world suffer from water shortagers.
C.The underground water in Saudi Arabia might run out in 50 years.
D.Good management of water use resulted from the project in the Central Valley.
3.What is most likely to be discussed in the paragreh that follows?
A.Steps to improving water use managet.
B.Ways tor redjuce the costs of builing dams.
C.Measured to dmal with worldwide water shortages.
D.Appmihes to handling the pressure on water supply.
4.The text is mainly about____________.
A.water supply and increasing population
B.water use management and agriculture
C.water redistribution and wildlife protection
D.water shornages and environmental protection.
