Without the atmosphere there would be no weather, no wind, rain, snow, or clouds. Air is all around us; we live at the bottom of a great ocean of air. It is invisible, but we can feel it when it moves. There are miles of air above us, pressing down with great weight on the earth and everything on it. Because air presses down on us from all directions at the same time, and because we are able to bear (忍受) this weight, we do not seem to feel it. But scientists have proved that air has this weight, and that anything that has weight creates(產(chǎn)生) a force called pressure. As changes in air pressure take place, they, make air move.
Air is a gas that expands(膨脹) when heated, gets lighter, and moves upward. When air is cooled, it gets heavier, sinks close to the earth's surface, and flows like water in a great river. As warn air rises, cold air rushes in to take its place. 'Thus winds originate (起源). The winds that blow high above us are caused by the warmer air running away from colder air. The wind we feel near the earth's surface is the heavy colder air trying hard to catch the warmer air. Changes in temperature cause the air to move. And of course there are many changes, so air movements are taking place practically all the time.
小題1:The first paragraph mainly tells us the causes of
A.why we don't feel airB.why atmosphere is important to us
C.why there is air surrounding usD.why there is air pressure
小題2:Air moves under such conditions that
A.there is air pressureB.the air is heavy
C.a(chǎn)ir pressure doesn't remain the same all the timeD.a(chǎn)ir comes up and down
小題3:Which of the following pictures best tells the movements of warm air and cold air?
小題4:According to the passage, in same areas if farmers who grow grapes (葡萄) light fires in the early morning, that is because the farmers want to________________.
A.drive away warm airB.prevent cold air from coming to harm their plants
C.cause more windD.stop warm air running away

One important attraction of walking is its long-lasting appeal. Whereas jogging and aerobic dancing can pall quickly, walking provides a popular activity that seems to endure. Fitness foundations estimate that 35 million adult Americans walk for exercise every day, with at least 15 million walking two or three times a week. Among the most regular walkers are those 65 years and older—evidence that walking is an exercise that lasts.
In addition to its many physical benefits, walking, like other physical activities, has a comforting effect on the psyche. Walking can help you to think more clearly and feel more relaxed. It also can be a sociable activity. An early morning walk around the neighborhood provides an opportunity to chat with friends or simply admire the  flowers. Or because it does not require a team or even a partner, walking is something you can do on your own time, by yourself, whenever the mood strikes.
Easily affordable, all you need to start walking is enthusiasm and a pair of comfortable and sturdy low-heeled shoes. Dr.ChristineL. Wells recommends an Oxford-style shoe with ties for better foot support; she does not recommend sneakers or other “cheapies”. If you plan to walk regularly, you might want to invest in a pair of so-called walking shoes. If so, expect to spend at least $35.
For walking during the hotter months, early morning or evening hours are best. Clothes should fit loosely and be lightweight and light-colored. Elderly walkers should consider wearing long sleeves, and all Arizonans need to be particularly concerned about skin cancer. Dr. Wells suggests wearing sunscreen as well as a side-brimmed hat to protect your eyes, ears, nose and back of the neck.
Walkers also should drink an adequate amount of water. Wells advises drinking an 8-ounce glass of water before you start out, and more when you return. “If you walk four miles or more a day in Arizona, I also recommend that you carry a water bottle,” she says. “ And water  is just fine; you don’t need those fluid-replacement or electrolyte drinks.”
小題1:The underlined word “pall” most probably means________.
A.interest peopleB.be easily learntC.become boringD.become popular
小題2:Which of the following is NOT mentioned as a benefit of walking?
A.It improves one’s appetite.B.It’s an inexpensive exercise
C.It helps to comfort the mind.D.it can be an individual or social activity
小題3:For regular walking, what you need most is _______.
A.enduranceB.enthusiasmC.strengthD.relaxation
小題4:We may infer from the passage that _______.
A.people in Arizona are easily exposed to strong sunlight.
B.walking is most suitable for those 65 years and older
C.water is better than any other drinks for walkers
D.jogging and dancing don’t have any positive effect on the mind.
小題5: Which word best describes the author’s attitude toward walking?
A.positiveB.playfulC.doubtfulD.cautious(謹慎)

閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項,并在答題卡上將該項涂黑。
Upon reaching an appropriate age, usually between 18 and 21 years, children are encouraged, but not forced, to “l(fā)eave the nest” and begin an independent life. After children leave home they often find social relationships and financial support outside the family. Parents do not arrange marriages for their children, nor do children usually ask permission of their parents to get married, Romantic love is most often the basis for marriage in the United States; young adults meet their future spousesthrough other friends, at jobs, and in organizations and religious institutions, Although children choose their own spouses, they still hope their parents will approve of their choices.
  In many families, parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do precisely the opposite of what their parents wish in order to assert their independence. A son may deliberately decide not to go into his father’s business because of a fear that he will lose his autonomy in his father’s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family Coexisting with such love in the American family are cultural values of self – reliance and independence.
1.The writer discusses the marriage of young adults in order to show         .
A.they choose their spouses according to their own wishes only

2.Most young adults in the U.S. get married for the sake of __    __.

Many of the employees think their career path and plans begin during their employment or when they already secured a job. But basically, if we look at what becomes of a person, you can root it from the upbringing of the person, to be more specific, from childhood.
As parents, we usually groom our children’s future according to what we are or what we wanted to be. We buy them toys and educational materials according to what we dream our children would become someday. For example, we know that becoming a teacher means a lot of sacrifices and lots of time worked but the pay is not satisfying. Thus, if we see this profession not favorable financially, we discourage our children from becoming teachers. However, the earliest exposure of children is usually in the medical field profession (every time they visit the hospital for consultation or any medical requirements) and the education or teaching profession (by the time they start attending classes). Information other than the two professions mentioned came from the parents and later exposure or experiences when they grew up and learn of their interest according to their special skills.
In career pathing, the parents’ role plays a major part for the individual’s success in identifying their chosen career. The best way is to support the child’s interest and not forcing them to take courses that the parents wanted for themselves. Support can be provided by helping them read materials on their field of interest, exposing them to the career and providing information as to the advantages and great efforts that one may take to accomplish their chosen field. This is not difficult nowadays. The internet and the publications are now very affordable and even the media provides the information for the different careers that our children may take. There are shows and programs that can provide a picture of the different field. But before you go to your television and change the channel of what your child is watching, check first if the program is fit for their age and maturity.
1. The underlined word “groom” in the second paragraph can be replaced by ___________.
A. take care of         B. prepare         C. expect          D. feed
2. Why does the parents’ role play a major part for the individual’s success in identifying their chosen career?
A. Because the best approach is to support the child’s interest.
B. Because parents can help them read materials on their interest.
C. Because parents can provide them with needed information.
D. Because parents’ help and support is extremely important.
3. Which of the following can be the best title for the passage?
A. The earlier, the better                     B. Work from childhood
C. Career Path Begins During Childhood        D. Parent’s support in choosing a career
4. It can be inferred that __________.
A. parents play a major part in helping their children choose their career
B. parents have a great effect on their children’s life
C. one’s early education is very important
D. getting information about jobs is not difficult nowadays because of the internet

For some time past it has been widely accepted that babies----and other creatures----learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的) “drive” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
Paousek began his studies by using milk in the normal way to “reward” the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children’s response in situation where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement “switched on a display of lights---- and indeed that they were able to learn quite complicated turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
Papousek’s light display was placed directly in front of the babies and he made the interesting observation that sometimes they would turn back to watch the lights closely although they would “smile and bubble” when the display came on. Papousek concluded that it was not primarily the sight of lights which pleased them, it was the success that they were achieving in solving the problem, in mastering the skill, and that there exists a primary human urge to make sense of the world and bring it under intentional control.
72.According to the author, babies learn to do things which ____.
A. are directly related to pleasure          B. will meet their physical needs
C. will bring them a feeling of success          D. will satisfy their curiosity
73.Papousek noticed in the studies that a baby ____.
A. would make learned response when it saw the milk
B. would carry out learned movements when it had enough to drink
C. would continue the simple movements without being given milk
D. would turn its head to right or life when it had enough to drink
74.In Papousek’s experiment babies make learned movements of the head in order to ____.
A. have the lights turned on              B. be rewarded with milk
C. please their parents                   D. be praised
75.According to Papousek, the pleasure babies get in achieving is a reflection of ____.
A. a basic human desire to understand and control the world
B. the satisfaction of certain physiological needs
C. their strong desire to solve complex problem
D. an important human urge to display their learned skills

Many Going to College Are Not Ready
Only about half of this year’s high school graduates have the reading skills they need to succeed in college, and even fewer are prepared for college-level science and math courses, according to a yearly report from ACT, which produces one of the nation’s leading college admissions tests.
The report, based on scores of the 2005 high school graduates who took the exam, some 1.2 million students in all, also found that fewer than one in four met the college-readiness benchmarks (基準)in all four subjects tested: reading comprehension, English, math and science.
ACT sets its college-readiness benchmarks — including the reading comprehension benchmark, which is new this year—by correlating(聯(lián)系)earlier students’ ACT scores with grades they actually received as college freshmen. Based on that data, the benchmarks indicate the skill level at which a student has a 70 percent likelihood(可能性)of earning a C or better, and a 50 percent chance of earning a B or better.
Among those who took the 2005 test, only 51 percent achieved the benchmark in reading, 26 percent in science, and 41 percent in math; the figure for English was 68 percent. Results from the new optional ACT writing test, which was not widely taken this year, were not included in the report.
About 40 percent of the nation’s 2005 high school graduates took the ACT, and the average overall score was unchanged from the year before. Minority students make up 27 percent of all ACT test takers. Besides, there are also other worrying trends in the ACT report as well, including a continuing decline in the percentage of students planning to major in engineering, computer science and education.
50. The report from ACT mainly tells readers the problem that ______.
A. few minority students graduates took ACT
B. many who intend to go to college are not ready
C. the college-readiness benchmarks is high this year
D. the tests for some subjects are too difficult
51. According to the benchmarks in 2005, about how many students will not earn C?
A. 30 percent.      B. 70 percent.      C. 50 percent.       D. 26 percent.
52. Which of the following pictures can correctly show the numbers of the students who achieve the benchmark in different subjects?
A.        B.
C.        D.
53. Which of the followings can be found in the report from ACT in 2005?
A. The report about the writing test is very objective.
B. More boy students are not good at science and math.
C. The percentage of students majoring science declined.
D. The average score of 2005 ACT participants changed greatly.

"Tear’em apart!" "Kill the fool!" "Murder the referee(裁判)!"
They are common remarks one may hear at various sporting events. At the time they are made, they may seem innocent(無害的)enough. But let's not kid ourselves. They have been known to influence behavior in such a way as to lead to real bloodshed(流血).Books have been written about the way words affect us. It has shown that words having certain meanings may cause us to react in ways quite foreign to what we consider to be our usual humanistic behavior. I see the term "opponent" as one of those words. Perhaps the time has come to delete it from sports terms.
The dictionary meaning of the term "opponent" is "enemy":“ one who opposes your interests." Thus, when a player meets an opponent, he or she may tend to treat that opponent as an enemy. At such times, winning may control one's mind, and every action, no matter how bad, may be considered correct . I recall an incident in a handball game when a referee refused a player's request for a time out for a glove change because he didn't consider them wet enough. The player rubbed his gloves across his wet T-shirt and then shouted, "Are they wet enough now?"
In the heat of battle, players have been observed to throw themselves across the court without considering the consequences that such a move might have on anyone in their way. I have also witnessed a player reacting to his opponent's intentional and illegal blocking by hitting him with the ball as hard as he could during the course of play. Off the court, they are good friends. Does that make any sense? It certainly gives proof of a court attitude which is different from normal behavior.
Therefore, I believe it is time we promoted the game to the level where it is by setting an example. Replacing the term “opponent” with “ associate” could be an ideal way to start.
The dictionary meaning of the term “associate” is “friend”;“companion.” Think it over!You may soon see and possibly feel the difference in your reaction to the term "associate' rather than "opponent."
49. Which of the following statements best expresses the author's view?
A. Bad behavior in sports will always have serious consequences.
B. The words people use can influence their behavior.
C. Unpleasant words in sports are often used by foreign athletes.
D. Unfair judgments by referees will lead to violence on the sports field.
50. Rough words are spoken during games because the players________.
A. are too eager to win                   B. are usually bad-tempered  
C. can't afford to be polite in competitions    D. treat their friends as competitors
51. What did the handball player do when he was not allowed a time out to change his gloves?
A. He refused to continue the game.
B. He angrily hit the referee with a ball.
C. He claimed that the referee was unfair.
D. He wet his gloves by rubbing them across his T-shirt.
52. The author hopes to have the current situation in sports improved by_______.
A. changing the attitude of players on the sports field
B. raising the referee's sense of responsibility
C. calling on players to use clean language on the court
D. regulating the relationship between players and referees
