It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous(災(zāi)難的). A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
小題1:As pointed out at the beginning of the passage, people used to think that air pollution ______.
A.caused widespread damage in the countryside
B.a(chǎn)ffected the entire eastern half of the United States
C.a(chǎn)lmost brought worldwide effect
D.existed merely in urban and industrial areas
小題2:As far as the greenhouse effect is concerned, the author _____________.
A.shares the same view with the scientists
B.is uncertain of its occurrence
C.rejects it as being ungrounded(無(wú)根據(jù)的)
D.thinks that it will increasingly destroy the world soon
小題3:It can be inferred from the passage that                   .
A.raising the world’s temperature a little would not do much harm to life on the earth
B.lowering the world’s temperature a little would lead to agricultural disasters
C.a(chǎn)lmost no temperature variations have occurred over the past decade
D.the world’s temperature will remain stable forever
小題4:This passage is primarily concerned with             .
A.the greenhouse effect in the world
B.the measures to adjust the climate
C.the potential effect of air pollution
D.the measures to protect the environment

Fire fighting is a serous matter, knowing what to do during a fire can save people’s lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators.
From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.
The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about twice the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.
小題1:Which of the following should not be used when trying to escape from a fire?
A.Windows B.ElevatorsC.Fire exitsD.Stairways
小題2:How far from the ground is the second floor window?

Imagine that the genome (基因組) is a book. The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book, or as long as 800 Bibles. If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube. This is an enormous document. A huge volume, a cook book of great length, and it all fits inside the extremely small nucleus (核) of a tiny cell that fits easily upon the head of a pin.
The idea of the genome as a book is not, strictly speaking, even a metaphor (比喻), It is true to a great extent. A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of letters into a large dictionary of meanings through the order of their groupings. So is a genome. The only complication is that all English books read from left to right, while some parts of the genome read from left to right, and some from right to left, though never both at the same time.
While English books are written in words of different lengths using twenty-six letters. Genomes are written entirely in three-letter words, using only four letters, And instead of being written on flat pages, they are written on long chains of DNA molecules (分子), The genome is a very clever book, because in the right conditions it can both photocopy itself and read itself.
小題1:How do human genomes read according to the passage?
A.Only from left to right.B.Only from right to left.
C.From both directions at the same timeD.From one direction at a time
小題2:We can learn from the passage that the human genome ______.
A.is as long as the River Danube
B.can be easily placed on the head of a pin
C.is coded with and alphabet of four letters
D.is smart enough to read and take photos of itself
小題3:It can be concluded that the passage is mainly written for ______.
A.specialists in the field B.general readers
C.natural scientistsD.readers with academic background
小題4:The real purpose of the author’s comparison of the genome to a book is ______.
A.to focus on the differences between the two
B.to lay emphasis on the similarities between the two
C.to simplify the concept of the human genome
D.to give an exact description of the human genome

Honestly, since my son was born, I have thought a lot about how to raise a child. I once heard a story that told about when a baby was born. The story said that when a baby was born, a new master was born. The parents of that baby would become the servants. The question is: Why? Based on my observation, this phenomenon is true. Most parents who don't pay much attention to their kids have difficulties with their kids' attitude.
I'll make a comparison of how two families raise their children. The first one is a family with three children. Both mother and father never say "No" to their children's demands. As a result, all of their children became stubborn and won't listen to their parents’ words, "We can't."
The second family educated their children strictly from one year old to high school. The parents never approved or agreed directly to give their children what they wanted. They always postponed one or two days, even if they could afford it. Due to the way their parents educated them, these children understood that if they wanted something, they had to wait or they had to make an effort first. As a result, all the kids from the second family successfully graduated from university on time.
In my opinion, if we want to be successful parents and raise our children well, we have to start disciplining them when they are toddlers but not wait until they become teenagers.
小題1:Why did the writer give two different stories in this passage?
A.To help prove his opinion about raising a child.
B.To list different ways that parents may take.
C.To criticize some parents’ foolish action.
D.To prove that his way of education is right.
小題2:What does the underlined word “postponed” in the third paragraph mean?
A.Carried out at once.B.Gave up.
C.Put off.D.Made a decision.
小題3: In the writer’s opinion, which of the following about raising a child is TRUE?
A.Children should be respected once they were born.
B.Parents should educate their children as early as possible.
C.It is right time to educate their children when they are teenagers.
D.Children should be helped whenever they make mistakes.
小題4: What do you think is the best title of this passage?
A.Make a comparison of how two families raise their children
B.To be successful parents
C.How to raise children well
D.Educate children strictly from one year old to high school

Experts say the American state of Hawaii has been invaded (入侵)by a small frog called the coqui (ko--kee). There may be millions of the small frogs in Hawaii. However, they do not belong there. They are normally found in the southeastern United States. The coqui frogs are harming Hawaii’s environment. And the extremely loud noise they make is causing problems for Hawaiian citizens and visitors.
The coqui invaders arrived in Hawaii about ten years ago. They were believed to have been brought in accidentally in shipments of plants from Florida. Their number has sharply increased. They have quickly spread around the Hawaii Islands hidden in plants.
The coqui is a brown frog about five centimeters long. During the day, the frogs hide in wet protected areas, such as under plant leaves. At night, the frogs move onto trees to feed, call to females and mates. The call of the male coqui sounds like. Ko kee! Ko kee!
In the southeastern United States, local people celebrate coqui frogs. But in Hawaii, the foreign frog has been considered as a harmful animal. The coqui frogs are a major danger to Hawaii’s environmental system. The frogs eat thousands of insects (昆蟲)every night. These insects are important for the reproduction of plants. The insects also are important food for Hawaii’s native rare birds. The frogs also are affecting the tourism industry in Hawaii. Increasing numbers of hotels, visitors and local people have been annoyed by the loud calls made by male coqui frogs to female frogs. At night, the noise often makes it difficult for people to sleep.
The frogs do not have any natural enemies in Hawaii to reduce their population size. The warm weather permits them to lay eggs all year long. There are many efforts in Hawaii designed to stop the spread of the coqui. It is a crime to transport ,sell or release(釋放)the frogs there.
The Hawaii Department of Agriculture is trying to find an effective chemical that can be safely used to kill the frogs. For now, the frogs may only be caught by hand. The Hawaii Department of Agriculture says the greatest danger to the economy and environment of the state is from harmful species, like the coqui.
小題1:The statement that can best summarize the main idea of the passage is         .
A.the coqui invaders have seriously affected the tourism industry in Hawaii
B.it is not permitted to transport, sell or release the coqui frogs in Hawaii
C.the coqui invasion has serious effects on the economy and environment in Hawaii
D.great efforts have been made by the Hawaii people to kill the coqui
小題2:The coqui frogs originally arrived in Hawaii            .
A.by chanceB.a(chǎn)t the request of all the local citizens
C.a(chǎn)s a giftD.a(chǎn)s goods demanded in the local market
小題3:Visitors to Hawaii don’t like the coqui frogs mainly because                 .
A.they are a big danger to the environmental system there
B.the loud noise made by the frogs bother their rest at night
C.they affect the reproduction of the local plants and insects
D.visitors could no longer see the native rare birds because of them
小題4:The two factors leading to the rapid spread of coqui frogs in Hawaii are           .
A.the frogs’ habit and the environment in Hawaii
B.the large number of the insects and the plants in Hawaii
C.the geographic location of Hawaii and its tourism industry
D.the warm weather there and the frogs’ lack of natural enemies

Cities need to put efforts to deal with pollution and clear the air.
Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015, according to the latest plan released by the State Council.
Besides the existing pollution control program for S02, regional emission caps (區(qū)域排放上限) for other certain chemicals will be established in the three key air polluting areas— rhe Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region.Coal-consumption caps will also be tried out in some areas, according to the plan.
The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people's health, Zhang Lijun, vice-minister of environmental protection, said in an interview on Monday.
The air quality in a city affects the regions nearby because pollutants (污染物)can travel through the atmosphere, said Chai Fahe, vice-director of Chinese Research Academy of Environmental Sciences.
“So efforts to reduce air pollution in a single city, targeting a certain pollutant will not oe enough," Chai said.
Zhang said the country's major industrial districts—the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region—have recorded more than 100 misty days annually in recent years.
These three regions, home to at least 200 million people, occupy only 6.3 percent of the country's area but consume 40 percent of the country's coal and produce half of its steel, according to official figures.
Studies also show that the visibility (能見(jiàn)度) in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s, as a result of air pollution.
Liaoning province, the Shandong Peninsula, Wuhan in Hubei province and its surrounding area, the Changsha-Zhuzhou-Xiangtan region in Hunan province, the Chengdu-Chongqing region, and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs, according to the plan.
The new plan also requires an improved air quality system, which will measure the pollution levels."The current system, which only measures some major pollutants, cannot reflect the true picture." said Chai.
小題1:It will not be enough to reduce air pollution in a single city because ______.
A.a(chǎn)ir pollution has been becoming more and more serious in recent years
B.a(chǎn)ir pollution like acid rain and smog is threatening people's health
C.a(chǎn)ir pollutants in a city can travel in the sky and affect nearby areas
D.a(chǎn)ir pollutants stay in fixed places over the cities
小題2:Suppose the visibility in eastern regions of China was 130 km in the early 1960s, the visibility there nowadays is           .
A.123 to 115 km
B.137 to 145 km
C.123 to 145 km
D.115 to 137 km
小題3:The main purpose of the passage is        .
A.to inform readers of the damage caused by air pollution
B.to introduce the new plan to control air pollution
C.to provide official figures of air pollution levels
D.to point out the regions affected by air pollution
小題4:What does the underlined phrase "the true picture" in the last paragraph mean?
A.The major pollutants.
B.The key polluted areas.
C.The major polluted cities.
D.The pollution levels.

Among various programmes, TV talk shows have covered every inch of space on daytime television. And anyone who watches them regularly knows that each one is different in style. But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey shows.
Jerry Springer could easily be considered the king of “rubbish talk”. The contents on his show are as surprising as they can be. For example, the show takes the ever-mon talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people’s lives.
Like Jerry Springer, Oprah Winfrey takes TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.
pared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a “final word”. He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. The show’s main viewers are middleclass Americans. Most of these people have the time, money, and ability to deal with life’s tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society. These are 18-to-21-year-olds whose main troubles in life include love, relationship, sex, money and drug. They are the ones who see some value and lessons to be learned through the show’s exploitation.
小題1:pared with other TV talk shows, both the Jerry Springer and the Oprah Winfrey are ____.
A.more interestingB.more formal
C.more detailedD.unusually popular
小題2: Which of the following is likely to be a topic of the Oprah Winfrey show?
A.Family ine planning.B.Nation hatred.
C.A new type of robot.D.Street accident.
小題3:We can learn from the passage that the two talk shows_____.
A.have bee the only ones of its kind
B.a(chǎn)ttract different people
C.a(chǎn)ppear at different times of the day
D.exploit the weaknesses in human nature
