阅读理解诶。     Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This
kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for
years. Now researchers say there are three different types of loneliness.
     The first kind of loneliness is temporary (暂时的). This is the most common type. It usually disappears
quickly and does not require any special attention. The second kind, situational loneliness, is a natural result
or a particular situation-for example, a family problem, the death of a loved one, or moving to a new place.
Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually
does not last for more than a year.
     The third kind of loneliness is the most severe. Unlike the second type, chronic (长期的) loneliness usually
last more than two yeas and has no specific cause. People who experience habitual loneliness have problems
socializing and becoming close to others. Unfortunately, many chronically lone people think there is little or
nothing they can do to improve their condition.
     Psychologists (心理学家) agree that one important fact in loneliness is a person"s social contacts, e.g,
friends, family members, co-workers, etc. We depend on various people for different reasons. For instance,
our families give us emotional support, our parents and teachers give us guidance, and our friends share similar
interests and activities. However, psychologists have found that, though lone people may have many social
contacts, they sometimes feel they should have more. They question their own popularity.
     Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy
and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart
disease. While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness
can be a very sad, and sometimes dangerous condition. 1. How would you treat temporary loneliness according to the passage? [     ]
A. Talk to friends
B. Just ignore it
C. Go to see a doctor
D. Ask your teachers for guidance 2. The topic of the 4th paragraph is that _____. [     ]
A. lonely people don"t have many friends
B. lonely people don"t have many social problems
C. one problem of loneliness is a person"s social contacts
D. we depend on various people for different reasons 3. Why do psychologists want to help chronically lonely people? [     ]
A. Chronic loneliness can cause family problems
B. Chronic loneliness can cause serious illness
C. Chronic loneliness cannot be overcome
D. A, B, and C are all correct 4. What is the best title of the passage? [     ]
A. Three kinds of Loneliness
B. Loneliness and Diseases
C. Loneliness and Social Contacts
D. Chronic Loneliness

阅读理解。     In America, drivers" education is part of the regular high school curriculum (课程). Every student in his
or her second year of high school is required to take a class in driver"s education. However, unlike other
courses, it is not given during the regular school year. Instead it is a summer course.
     The course is divided up into two parts: class time for learning laws and regulations, and driving time to
practise driving. Class time is not unlike any other class. The students study the basic traffic laws from a text
to pass the written driving test that is given to anyone who wants to get a driver"s license.
     Driving time is a chance for the students to get behind the wheel (steering wheel) and practise starting
steering, backing up, parking, switching lanes, turning corners, and all the other maneuvers (操作) required
to drive a car. Each student is required to drive a total of six hours. The students are divided up into groups
of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets
half an hour driving time per outing. The instructor and "driver" sit in the front seats and the other three
students sit in the back.
     After the student has passed the driver"s education course and reached the appropriate age to drive (this
age differs in every state but in most cases the person must be 16 years old), they can go to a designated (指
定的) state office to take their driver"s test, which is made up of an eye examination, a written test, and a
road test. The person must pass all three tests in order to be given a driver"s license. If the person did well in
his or her driver"s education class, he or she will pass the test with flying colors and get a driver"s license. 1. In America, the driver"s course mentioned above _____. [     ]
A. is considered as part of the advanced education
B. is given to anyone wanting to get a driver"s license
C. is carried on at the same time as other courses
D. is offered to all the students of Grade 2 in high schools 2. We can infer that the students are required to _____ in their whole driving practice. [     ]
A. spend at least six hours driving
B. get half an hour driving
C. drive for two hour blocks of time
D. go out driving for twelve times 3. Which of the following is Not True for the students wanting to get their driver"s license?[     ]
A. They must have their eyes examined.
B. They must be 16 years of age.
C. They should go to have their driver"s test.
D. They ought to do well in their driver"s course. 4. In the last sentence, "with flying colors" means _____.[     ]
A. happily
B. quickly
C. colorfully
D. successfully

任务型填空。     People who are concerned about pollution will be happy to know that clean and renewable energy sources
that protect the environment such as solar energy are becoming possible alternatives.
     Increasing demand for clean, renewable energy is driving a growing market for solar energy products..
Two of the main types of products that take advantage of solar energy are passive and active solar products.
These two types of systems differ in how they are constructed and can also differ greatly in cost. Passive solar
technology can be used to heat air or water directly using the sun"s energy. Unlike an active solar application,
passive solar set-ups accomplish their task without the use of additional electrical components, such as fans
that need an external electricity supply. Some solar space heating or water heating systems are active solar
heating systems that have various components that call for external power sources. Because of their simplicity
compared with active systems, passive solar heating systems generally are cheaper than active ones.
     In addition to these solar heating systems, there are also solar power system available. Rather than using the
sun"s energy for heating applications, these systems change solar energy into electricity. An important part of
these products is called photovoltaic cells, which generate electricity from light. As sunlight falls on a
photovoltaic cell, the light"s energy is changed into electricity that can then be used to power many kinds of
electronic devices. Because of the complicated technology involved, these kinds of solar power systems can
be very expensive.
     When considering what kind of solar heating or power system to install (安装) in your home or business,
be sure to purchase your equipment from a reputable manufacturer who will be able to help you with any
necessary repair.

     Batteries can power anything from small sensors to large systems. While scientists are finding ways to
make them smaller but even more powerful, problems can arise when these batteries are much larger and
heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy
source that is smaller, lighter and more efficient.
     "To provide enough power, we need certain methods with high energy density (密度)", said Jae Kwon,
assistant professor of electrical and computer engineering at MU. "The radioisotope (放射性同位素) battery
can provide power density that is much higher than chemical batteries."
     Kwon and his research team have been working on building a small nuclear battery, presently the size and
thickness of a penny, intended to power various micro / nanoelectromechanreal systems (M/NEMS). Although
nuclear batteries can cause concerns, Kwon said they are safe.
    "People hear the word "nuclear" and think of something very dangerous," he said, "However, nuclear power
sources have already been safely powering a variety of devices, such as pace-makers, space satellites and
underwater systems."
     His new idea is not only in the battery"s size, but also in its semiconductor (半导体). Kwon"s battery uses
a liquid semiconductor rather than a solid semiconductor.
    "The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy
can damage the lattice structure (晶体结构) of the solid semiconductor," Kwon said, "By using a liquid semicon
ductor, we believe we can minimize that problem."
     Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor,
Kwon is working to build and test the battery. In the future, they hope to increase the battery"s power, shrink
its size and try with various other materials. Kwon said that battery could be thinner than the thickness of
human hair.

1. Which of the following is true of Jae Kwon? [     ]
A. He teaches chemistry at MU.
B. He developed a chemical battery.
C. He is working on a nuclear energy source.
D. He made a breakthrough in computer engineering. 2. Jae Kwon gave examples in Paragraph 4 _____. [     ]
A. to show chemical batteries are widely applied.
B. to introduce nuclear batteries can be safely used.
C. to describe a nuclear-powered system.
D. to introduce various energy sources. 3. Liquid semiconductor is used to _____. [     ]
A. get rid of the radioactive waste
B. test the power of nuclear batteries
C. decrease the size of nuclear batteries
D. reduce the damage to lattice structure4. Liquid semiconductor is used to _____. [     ]
A. get rid of the radioactive waste
B. test the power of nuclear batteries
C. decrease the size of nuclear batteries
D. reduce the damage to lattice structure5. The text is most probably a _____. [     ]
A. science news report
B. book review
C. newspaper ad
D. science fiction story

阅读理解。      Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies
like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings when young.
They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young.
It is called the hoatzin.
     In appearance, the birds of both sexes look very much alike with brown on the back and cream and red
on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its
nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.
     Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using
these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like
primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.
     During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30
birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven
birds for producing purposes. 1. What is the text mainly about? [     ]
A. Hoatzins in dry and rainy seasons.
B. The relatives and enemies of hoatzins.
C. Primitive birds and hoatzins of the Amazon.
D. The appearance and living habits of hoatzins. 2. Young hoatzins are different from their parents in that _____. [     ]
A. they look like young cuckoos
B. they have claws on the wings
C. they eat a lot like a cow
D. they live on river banks 3. What can we infer about primitive birds from the text? [     ]
A. They had claws to help them climb.
B. They could fly long distances.
C. They had four wings like hoatzins.
D. They had a head with long feathers on the top. 4. Why do hoatzins collect together in smaller groups when the rainy season comes? [     ]
A. To find more food.
B. To protect themselves better.
C. To keep themselves warm.
D. To produce their young.

阅读理解。     Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the
existence of creatures and even whole societies beyond our everyday lives.
    This sense of wonder is universal. Look at the efforts that scientists have made to find out whether life of
some kind exists on Mars, and the popularity of fantasy (幻想) literature or movies like The Lord of the Rings.
This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But
have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already
exist all around us?
     Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other
life forms. However, people, especially in big cities, often lead rather isolated lives. In a study of British
schoolchildren, it was found that children by age eight were much more familiar with characters from television
shows and video games than with common wildlife. Without modern technology, a small pond could be an
amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful
interaction (交互) with the world around us, and sometimes even with our families and friends, we seek to
understand and communicate with things that exist only in our imaginations or on a computer screen.
     The world of make-believe is not necessarily bad. But when the world of fantasy becomes the only outlet
(出路) for our sense of wonder, then we are really missing something. We are missing a connection with the
living world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely
enough, we can see that these worlds, in a broad sense, are really part of our own. 1. The popularity of The Lord of the Rings proves _____.[     ]
A. the close connection between man and the fantasy world
B. the wonderful achievements of fantasy literature
C. the fine taste of moviegoers around the world
D. the general existence of the sense of curiosity 2. What can we infer from the underlined sentence in Paragraph 3? [     ]
A. People are far less familiar with the world of fantasy.
B. The world around us could serve as a source of wonder.
C. The world of fantasy can be mirrored by a small and lively pond.
D. Modern technology prevents us from developing our sense of wonder. 3. If our sense of wonder relies totally on the world of make-believe, we will _____.[     ]
A. fail to appreciate the joy in our lives
B. be confused by the world of make-believe
C. miss the chance to recognize the fantasy world
D. be trapped by other worlds existing all around us 4. What is the main purpose of the passage? [     ]
A. To show us the hidden beauty in our world.
B. To warn us not to get lost in the fantasy world.
C. To argue against the misuse of the sense of wonder.
D. To discuss the influence of the world of make-believe.
