About half American teenagers do not get enough sleep on school nights.They get an average of sixty to ninety minutes less than experts say they need.
One reason for this is biology.Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups.Yet many schools start classes as early as seven in the morning.As a result,many students go to class feeling like sixteen?year?old Danny.He is an active teen— except in the morning.“Getting up in the morning is pretty terrible.I’m just very out of it and tired.Through the first and second period I can hardly stay awake,” he said.
Michael Breus is a psychologist.Teens,he says,need to sleep eight to nine hours or even nine to ten hours a night.He says sleepy teens can experience a form of depression(消沉) that could have big influence on their general well being.It can affect not just their ability in the classroom but also on the sports field and on the road.So what can schools do about sleepy students?The psychologist says one thing they can do is to start classes later in the morning.Studies show that students can improve by a full letter grade in their first and second period classes.
Eric Peterson is the head of St.George’s School in the northeastern state of Rhode Island.He wanted to see if a thirty?minute delay(推遲)would make a difference.It did.He says visits to the health center by tired students decreased by half.Late arrivals to the first period fell by a third.And students reported that they were less sleepy during the day.Eric Peterson knows that changing start times is easier at a small school like his.But he is hopeful that other schools will find a way.
小題1:What’s the best title for the passage?
A.Later classes,fewer sleepy teens
B.Early birds have good food
C.Early to bed and early to rise
D.Fewer classes,more happiness
小題2:The underlined word“this”in the second paragraph refers to________.

We live in a dangerous world. The figures for crime go up year by year. If you were attacked in the street, would you be able to defend yourself? Not very well probably, especially if someone was pointing a gun at you. We all see a lot of violence of films, but recently some programs on television showed how people can defend themselves without guns. For example, in one film a woman was attacked from behind. She threw the man, who was heavier and stronger than she was, over her head. Then she held him tightly on the ground. How? She knew Judo.
Jiu-jitsu, as judo is sometimes called, means "muscle science" in Japanese. The student of judo needs to learn a lot about the body, its bones and muscles. Judo uses a number of "falls", "holds" and "throws". Someone who does not know judo cannot defend himself against them. If you know judo you can defend yourself against a person who is stronger than you. You had better not practice judo on your friends unless they can fall without hurting themselves! Being strong is one thing, but using the body wisely is another. In judo, you use the other person's body to help you. You "throw" him to the ground and "hold" him there, so that he cannot move. Of course, it takes time and practice, but knowing judo is useful. In a violent world you ought to be able to defend yourself.
小題1:According to passage, in fact "judo" is ______.

Almost everyone suffers from a headache sometimes.But some people suffer from repeated, frequent headaches.
What is headache? What causes it? What can be done about a headache? What research is being done on headaches?
The dictionary defines(下定義) headache simply as “a pain in the head.” What most people mean by headache is a pain which lasts several minutes or hours.It covers the whole head, or one side of it, or perhaps the front or the back of the head.To add to the confusion(困惑) about a definition, some people call tight feeling in the head a headache.
A headache is important because it can be the first warning of a serious condition which probably could be controlled if discovered early.If a person removes the warning, day after day, with a pain-killer, he may pass the point of easy control.
The professional name for covering up a symptom(癥狀) is “masking” (遮蔽).A headache specialist once said, “Masking symptoms is not the best way of treatment.” He compared taking a pain-killer for a headache before a cause is known with taking iron pills for anemia(貧血癥) while bleeding continues undiscovered.He added, “Sometimes it is wiser to stand still than to advance in darkness.
A headache is important also because it affects normal, happy living.The employee with a headache does less work.In a flash of temper he may upset his fellow workers or customers, causing a direct or indirect loss to his organization.The mother with a headache suffers and disturbs the family.She upsets her husband and children.
小題1:Which is true according to the passage?

Your Car Is Ready for Take-off
The flying car has been talked about for many years,but now it appears that the idea is about to become a reality.
An international company has built a two-seater plane that, at the touch of a button ,transforms into a car perfectly suitable for driving on public roads. It has been designed so that the wings fold up automatically; and it takes just 15 seconds to switch between flying and driving. With its wings fully open and the propeller(螺旋槳)spinning, it can take off from any airfield.
Flying cars are quicker than traditional ones for travelling from city to city,and they can run on ordinary fuel. Another big advantage is that they are cool ,like something you would see in an action film. At the moment 9 however, the flying car’s wheels are illegal to leave the ground. That is not because of technical reasons or problems with the design. It is because the various road and aircraft authorities simply cannot agree on whether it is a car or a plane.
“The government and the authorities have never thought seriously about a flying car, says Alan Price ,the president of the company that has developed it. “I wanted a car that could fly and drive ,but it is difficult to find an organization prepared to insure the vehicle against accidents.
Nevertheless ? the company hopes to produce and deliver its first flying car soon. The company already has orders for 40 of them. The majority the potential customers are older and some are retired。There have even been orders from some people who have no pilot's license.
The flying car will cost around $ 200.000. “For an airplane , thats a very reasonable price, but for a car, It's quite expensive,” explains Alan. “But it just is not possible to make a $ 10,000 flying car yet. ”
This latest means of transport will not become a mass-market item in the near future,but in the long term it has the potential to change the way you travel. It will become no more expensive than driving your car on the motorway. Travel time could be reduced by more than half.
So the next time you are told to fasten your seat belt, it may be to prepare for take-off.
小題1:We know from the passage that the flying car______
A.has to run on special fuelB.will replace traditional planes
C.is popular with the richD.can shift between two forms
小題2:The flying car is presently forbidden to take off because______.
A.many people think driving it not very safe
B.it’s hard to decide whether it's a car or a plane
C.the government and the authorities don’t accept it
D.there are still some technical problems to be solved
小題3:We can learn from the passage that______.
A.few people will be able to afford a flying car
B.flying cars may share the market in the future
C.traffic jams will disappear because of flying cars
D.driving a flying car doesn’t require a pilot’s license

These days, young children can enjoy directly what it is like to be a marine biologist (海洋生物學(xué)家) at a marine association. What they discover can lead them to appreciate and protect the ocean and also the animals living in it.
At the present time, learning isn’t only limited to the classroom. It’s quite common for kids to learn from outdoor experiences. Teachers commonly take their pupils on field trips to museums as well as other interesting areas. If you wish to help pupils to take care of the ocean, one of the best areas to take them to is a marine association, the place where the ocean biome (生物圈) is shown.
Taking your pupils to a marine association is a prefect way to help them learn. Education professionals agree that there are topics that children can learn more successfully whenever they experience them directly.
Several organizations that focused on protecting the ocean now operate on the coast of different areas in America and all around the world. It’s quite common for marine associations nowadays to open their doors several times a week to kids, parents, and ocean lovers to learn more about the ocean biome.
A marine association has different programs for children of different ages. You’ll find programs that are developed specially for pupils. Pupils are involved in interactive (互動的) learning. This learning experience allows young children to recognize the value of the role each species performs in their environment. They not only get to research creatures from the ocean, but they also get to see, touch, and smell most of these animals and plants. This type of exposure offers students an idea about the life of a marine scientist. It could help them choose a career afterwards.
These programs are generally held on Saturdays and Sundays in order that kids and parents can have more hours in which to have fun. Teachers who want to arrange these activities for their students can call a local marine association near them.
小題1:According to the text, pupils can have a better understanding of the ocean biome by _______.
A.learning about it from books
B.going to a marine association
C.a(chǎn)ttending marine biologists’ meetings
D.taking part-time jobs at marine associations
小題2:In Paragraph 5, the author mainly wants to tell us _______.

The massive magnitude(震級) 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.
Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.
The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic(地震的) stresses which encircles(環(huán)繞,包圍) the Pacific Ocean. All along this line, the plates on which the continents move press against each other.
Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal(地殼的)movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.
Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.
“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.
小題1:What is the main idea of the passage?
A.The earthquake in Chile was dangerous.
B.Earthquake often happen in Chile
C.The earthquake in Chile moved cities.
D.The earthquake in Chile had been predicted.
小題2:Which of the following cities moved to the west most?
A.ConcepcionB.Buenos AiresC.SantiagoD.Valparaiso
小題3: The underlined words “ring of fire” in Paragraph 4 refer to __________.
A.the fire and the earthquake
B.the beautiful places around the ocean
C.the plate on which South America lies
D.the area around the Pacific Ocean
小題4: What do we know about CAP?
A.It is under the leadership of Mike Bevis.
B.It observes earthquakes worldwide.
C.It is designed to watch climate changes.
D.It mainly studies the Pacific Ocean.

Aggie Bonfire (篝火) was a long-standing tradition at Texas A&M University as part of the college rivalry (競爭) with the University of Texas at Austin. For 90 years, Texas A&M students—known as Aggies—built and burned a bonfire on campus each autumn. Known to the Aggie community simply as "Bonfire", the annual autumn event symbolized Aggie students' "burning desires”. The bonfire was traditionally lit around Thanksgiving in connection with festivities surrounding the annual college football game.
Although early Bonfires were little more than piles of trash, as time passed, the annual event became more organized. Over the years the bonfire grew bigger, setting the world record in 1969. Bonfire remained a university tradition for decades until, in 1999, a collapse during construction killed twelve people—eleven students and one former student—and injured twenty-seven others.
The accident led Texas A&M to declare a pause on an official Bonfire. However, in 2002, a student-sponsored-and-off-campus "Student Bonfire" came up.
In 2003, the event became known as Student Bonfire. In a design approved by a professional engineer, Student Bonfire uses a wedding cake design, but, in a departure from tradition, every log in the stack (堆) touches the ground. For added support, four 24 feet poles are spaced evenly around the stack and then bolted to the 45 feet center pole with a steel pipe. Since the group does not receive funding, Student Bonfire charges a fee to each attendee to cover expenses. Attendance for Student Bonfire ranges from 8,000–15,000 people and the event is held in Brazos County or one of the surrounding counties.
小題1:When did Aggie Bonfire come into being?
A.In 2003.B.1999.
C.1909.D.2002.
小題2: Which of the following statements is true according to the above passage?
A.Texas A&M University started Aggie Bonfire.
B.The University of Texas at Austin started Students Bonfire.
C.Texas A&M University and The University of Texas started Students Bonfire.
D.Texas A&M University and The University of Texas started Aggie Bonfire.
小題3:Why did Aggie Bonfire once stop?
A.Too many people wanted to join in it.
B.Some serious accidents occurred during the activity.
C.It ran out of fund and then stopped.
D.There were no official supports.
小題4: Which of the following might serve as the best title of the whole passage?
A.From Aggie Bonfire to Student Bonfire.
B.A brief history of American Bonfire.
C.Why not join Bonfire?
D.Bonfire in Texas of the United States.

When children learn a language, they learn the grammar as well as words or vocabulary. No one teaches them; children just “pick them up”.
Before babies begin to produce words, they produce sounds. Some of these sounds will remain if they occur in the language being learned, and others will disappear. This is called the “babbling stage”.
A child does not learn the language “all at once”. The child first speaks only one-word “sentences”. After a few months, the two-word stage arises. During this stage, the child puts two words together. These two-word sentences have definite patterns and express grammatical and meaningful relationships. Still later, in the telegraphic stage, the child will produce longer sentences. These longer sentences are mainly made up of content words. The child’s early grammar lacks many of the rules of the adult grammar, but gradually it will become perfect.
All normal children everywhere learn language. This ability is not dependent on race, social class, geography, or even intelligence (智力). This ability is uniquely (獨(dú)特的) for human.
小題1:This passage is mainly about ___________.
A.differences between a child’s language and an adult’s
B.ways of teaching babies to talk
C.children’s learning of the mother language
D.the importance of learning foreign languages
小題2:The phrase “pick them up” means____________.
A.raise them from the ground
B.learn them without much effort
C.use hands to help carry them
D.study very hard and remember them
小題3:During the “babbling stage”, babies ___________.
A.can only produce sound
B.learn to work without falling over
