The United States has about 475,000 school buses ---all painted yellow.Each day they carry more than 25,000,000 children, half of all schoolchildren in the country.But these buses, on average, use four liters of diesel (柴油) fuel to travel less than sixteen kilometers.When the school year began last fall, diesel averaged 55 cents a liter nationally.The price nearly doubled, to a dollar and 8 cents, by the end of school in June.
Bob Riley speaks for the American School Bus Council.He says fuel prices for schools are not much lower than others have to pay.As a result, schools are looking for ways to reduce transportation costs.Bus routes are being redrawn or, in some cases, canceled (取消).Some areas are buying buses that use natural gas or other alternative fuels.Other steps include fewer field trips and less travel by sports teams.And some school districts (地區(qū)) may end any bus service not required by law.
Studies show that school buses are the safest form of transportation to and from school.The American School Bus Council says cuts in bus service are bad for children and possibly the environment.It says removing buses from the road will mean an increase in other vehicles transporting students.Spokesman Bob Riley says another concern is that reducing bus services might reduce attendance.
But it could also get more children to walk or bicycle to school.And that would surely make people happy at the National Center for Safe Routes to School.More kids walking or biking safely to school is the aim of a three-year-old federal program, part of an international movement.The goal is to increase physical activity and reduce air pollution.The United States will celebrate Walk to School Day on October the eighth this year.But for some students, high fuel prices could make every day a walk-to-school day.

We do not know when man first began to use salt, but we do know that it has been used in many different ways throughout history. Historical evidence shows, for example, that people who lived over 3,000 years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve (保存) the dead.
Stealing salt was considered a major crime (罪行) during some periods of history. In the eighteenth century, for example, if a person was caught stealing salt, he could be put in prison and his ears could be cut off.
In the Roman Empire, one of the most important roads was the one that carried salt from the salt mines to Rome. Guards were stationed along the route to protect against salt thieves, and they received their pay in salt, thus bringing the English word, salary. Any guard who fell asleep while on duty was thought to be “not worth his salt”, and as a result he would get a little less salt on his next payday. The expression, “not worth his salt”, is still used today in English.
In the modern world salt has many uses beyond the dining table. It is used in making glass and airplane parts, in the growing of crops, and in the killing of weeds (雜草). It is also used to make water soft, to melt (融化) ice on roads and highways, to make soap, and to fix colors in cloth.
Salt can be got in various ways besides being taken from mines underground. Salt water from the ocean, salt water lakes or small seas can be used to make salt. Yet, no matter where it comes from, salt will continue to play an important role in the lives of people everywhere.
小題1:According to the text, salt can be used in the following EXCEPT _____.
A．keeping dead bodies
B．punishing thieves
C．protecting crops
D．making industrial products
小題2:In the Roman Empire many people were employed as guards to _____.
A．protect the city of Rome
B．watch people carrying salt
C．prevent thieves from stealing salt
D．carry salt from the mines to Rome
小題3:The expression “not worth his salt” used today refers to the one who _____.
A．fails to do his work well
B．should not be paid in salt
C．doesn’t want to work at all
D．should use less salt
小題4:The main purpose of the text is to tell readers _____.
A．how salt was found and got

Most visitors come to the UK expecting the rain and weather for which the country is famous. However, when summer finally arrives, British people like nothing more than heading for the coast. Here are some of more famous places of interest that you could expect to visit on a trip to Britain. Black pool, in the northwest of England, is the most visited place in the UK. Each year around 6.5 to 7 million people come to enjoy the miles of sandy beaches, the 158m Black pool Tower and the 11km-long Golden Mile, where there are entertainments, pubs, ice rinks (溜冰場) and even a zoo. On the south coast of the country you can find Brighton. Until 1786, Brighton was a sleepy village. Then the future king, George IV, decided to build a house there, and now it has become a large, international centre. Apart from the beaches, Brighton is famous for its pier (碼頭). There are theatres, entertainments and restaurants there. Brighton is also fantastic for shopping. If you want to travel a little further, why not go to Corn-wall in the far southwest of the UK? South Cornwall offers miles of sandy beaches and beautiful scenery. The climate there is warmer than the rest of Britain, and you can even find palm trees. For a bit more excitement, go to North Cornwall. The scenery there is nicer, and the beaches are famous for their powerful waves. As a result, North Cornwall has become the home of British surfing. One word of warning though, if you are using the roads in the UK during holidays, you can expect long traffic jams on the motorways. It might be better to take the train.

Driving a car is not just handing controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant(抑制藥), damaging eyesight, judgement and co-ordination(協(xié)調(diào)), slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.
Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.
The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:
·50 milligrams of alcohol per 100ml of blood; or
·22 micrograms of alcohol per 100ml of breath; or
·67 milligrams of alcohol per 100ml of urine(尿液).
Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.
Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK＄25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points; or temporarily banned from driving.
The same punishment applies to failing to provide specimens(樣本) for breath, blood or urine tests without good excuse.
Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.
小題1: The first paragraph is mainly about       .
A．the introduction of driving skills
B．the damage of drinking to your body
C．the effect of drinking on driving
D．the process of alcohol being absorbed
小題2: The underlined word “it” in the second paragraph refers to “       ”.
A．a(chǎn)lcoholB．a(chǎn)bsorptionC．bloodD．process
小題3: Which of the following is TRUE according to the passage?
A．Drinking below the drink driving limit has no effect on driving.
B．Alcohol is taken in more quickly when drunk with fruit juice.
C．Having a cup of tea helps to get rid of alcohol from the body.
D．50 milligrams of alcohol per 100ml of breath is below the drink driving limit.

As computers become all the more popular in China, Chinese people are increasingly depending on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（筆畫）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.
Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their homework and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.
"When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I’m familiar with it."
"I'm not in the mood to write when faced with a pen and paper."
Many students don't feel this is something to worry about. Now that it's more convenient and quick to write on a computer, why bother to handwrite?
Many educators think differently. Shi Liwei , the headmaster of a famous primary school in the capital said "Chinese characters enjoy both practical and aesthetic(審美的) value. But those characters typed with computer keyboards only have their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion(情緒). Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.”
To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory(必修的)and in universities, some professors are asking students to turn in their homework and essays written by hand.
小題1:Which of the following can best serve as the title of the passage?
A．The Importance of Handwriting and Typing.
B．To Type or To Hand Write
C．Writing By Computer Will Replace Writing By Hand
D．Practical and Aesthetic Value of Chinese Characters.
小題2:The students interviewed prefer to write using a computer mainly because______.
A．they are usually asked to e-mail their homework and Essays
B．they can correct the mistakes they make quickly and conveniently
C．they find it not easy to remember how to write a character
D．computers have become popular in China.
小題3:Which of the following statements is NOT TRUE of the advantages of handwriting?
A．Handwriting contains the writer's emotion.
B．The writer’s thinking and personality are shown in his or her handwriting,
C．Handwriting can impress people well and build up one’s self-confidence
D．Chinese characters enjoy both practical and aesthetic value.
小題4:The underlined expression “taking stock in”(Paragraph 4) probably means_____.
A．getting bored withB．getting dependent on
C．becoming crazy aboutD．getting curious about
小題5:We can draw the conclusion from the passage that_______.
A．more and more students will give up writing on a computer

The early lack of exposure to science ，technology，engineering and mathematics (STEM) can be harmful to achieving gender (性別）balance in these fields. It begins when we are young and continues throughout our time in high school.
While at home，girls generally don’t get to experience the level of exposure or encouragement in STEM fields that their male counterparts do. It is often subtle ，but it’s the first hurdle that faces and confuses so many women. Boys ，on the other hand, get on their path ，and are encouraged to do so， generally earlier than girls. For example ，boys are more often given science sets as toys ，which spark an interest in these subjects.
In school 3 boys are often pushed to take the more challenging math and science classes. So if we want to attract the best and brightest minds into the fields that will advance us as a people ? a country，and a planet，we can no longer look to only half of the population. Young girls cannot possibly consider opportunities they do not know exist. If girls are not exposed to certain subject and career paths，they are highly unlikely to choose to follow them in college.
Our bias(偏見)toward girls9 either from families or from schools ，is so rooted in our culture that we often don’t even recognize it. Although the situation Has changed greatly in the past 20 or 30 years，there is still a sense that girls aren't as good at math 9 for instance 9 even though there is almost no evidence to support such a belief.
It is important that as a society we deal with gender stereotypes long before young people are faced with a decision to declare or choose a major in college. Without making efforts to break them， we are limiting the potentials of our youth，both male and female. Providing the necessary resources， exposure , and encouragement would help young women understand that their gender shouldn’t determine the career path they choose, and that pursuing a STEM career does not make them less feminine.
小題1:According to the passage ? not many girls grow to enter STEM fields because______.
A．girls are not as good at STEM as boys
B．girls do not like to take science classes
C．girls get fewer chances to know about STEM
D．girls seldom survive the high pressure positions
小題2:The underlined word “it” in Para. 4 refers to______
A．our biasB．our cultureC．the situationD．a(chǎn) sense
小題3:The main purpose of the passage is to______.
A．show women’s potentials in STEM fields
B．praise women’s contributions to STEM fields
C．describe the present gender bias in STEM fields
D．call for more involvement of women in STEM fields

Deception (騙術(shù)）is something that people do all the time ,and it plays an important role in military (軍事的)strategy. Now some researchers are trying to figure out how to get robots to do it, by looking at the behavior of squirrels and birds.
At Georgia Tech, a team led by Ronald Arkin , a professor at the School of interactive Computing, studied the literature on squirrels hiding their acorns (橡果）.Squirrels will hide their food m a certain place, but when they see other squirrels trying to steal from them, they attempt to fool the thieves by running to a fake location.
Ronald Arkin and his Ph. D. student Jaeeun Shim used that as a model for robot behavior. They programmed the robot into tricking a “predator (捕食者）” machine by doing what εi squirrel does： showing the enemy a false location for an important resource.
The team also looked at how other animals in this case，a species of bird called Arabian babbler~ drive off predators. A babbler will make an alarm call when they see a predator and other babblers will join the bird and make more calls. They then surround the predator, all the while flapping (拍打）wings and making noises. The babblers don’t ever actually fight the animal they want to drive off； they just make enough noises and flaps around enough so that it seems that attacking a babbler isn’t worth it
They found that the deception works when the group reaches a certain size—essentially, when enough birds arrive to convince the enemy that it’s best to back off . Davis modeled that behavior in software using a military scene and found that it worked even if the group didn’t have the firepower to confront the enemy directly.
The military is interested in this because a robot that can fool an opponent is a valuable tool. It could lead an enemy down a fake trail or make itself look more dangerous than it actually is.
小題1:Why does the military want to take advantage of squirrels’trick?
A．It can reduce the use of firepower to confront the enemy.
B．It can fool the enemy into believing it is more dangerous.
C．It can lead the enemy in a wrong direction to avoid losing resources.
D．It can scare the enemy away who wants to destroy the acorns.
小題2:Which of the following is NOT the way Arabian babblers drive off predators?
A．One bird makes an alarm call and other birds will join it
B．They fight the enemy bravely face to face.
C．They make noises and flaps around the predator.
D．They force the predator aware that it isn't worthwhile to attack.
小題3:What is the main idea of the passage?
A．Animals' behaviors are researched to be applied to the study of military robots.
B．Robots, fooling tricks are applied to the study of animals’behaviors.
C．Birds and squirrels are the animals that are good at deception.
D．Researchers are interested m animals’military-related behaviors.
