Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist has done some estimates and the results might surprise you.
Let's start with a very simple white puffy cloud — a cumulus cloud(積云). How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended in the sky begs another question — what keeps it up there?
"First of all, the water isn't in elephant sized particles(微粒), it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up the calculations for a hurricane about the size of Missouri and the figures get really massive. "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.
小題1:The weight of      is NOT mentioned in the passage.
A.a(chǎn) cumulus cloudB.a(chǎn) tornadoC.a(chǎn) hurricaneD.a(chǎn) storm cloud
小題2:How did Peggy LeMone feel about the result of her calculations?
A.She found it not convincing.
B.She thought it needed further calculations.
C.She was quite surprised at it.
D.She considered the calculations inaccurate.
小題3:What can be inferred from the passage?
A.A storm cloud weighs about 200,000 elephants.
B.The water in a hurricane weighs more than that in any other kind of cloud.
C.There are less than forty million elephants living on the earth.
D.The water in the cloud is in very tiny partials.

Sometimes educators need to be reminded that their job is important and they are very much appreciated. Here are some movies that inspire us and make educators feel proud to be in the field of education where they really do have an impact.
The Miracle Worker
The ultimate teaching miracle, Anne Bancroft is awesome as Annie Sullivan who uses ‘tough love' to get through to the deaf and blind Helen Keller played by Patty Duke. Very few people can watch the famous ‘water' scene without experiencing a feeling of victory and relief. Excellent portrayal of the importance of perseverance. Both Bancroft and Duke won an Academy Award for their performances.
The Karate Kid
While not normally thought of as a ‘classroom' movie, The Karate Kid has much to say to teachers: Sometimes we have to have our students do things that they will not understand until much later; Basic skills are most important; Honor and integrity are central to character; Students need to see us beam with excitement over their achievements. A fun, nostalgic and inspiring movie to relish.
To Sir With Love
Produced in 1967, this film with Sidney Poitier as a novice teacher has a lot to teach us today. Poitier takes a teaching position in the rough part of London in order to pay his bills. Realizing that his students need to be taught important life lessons more than the curriculum he has been handed to teach them, he throws out the lesson plans and makes a real impact on their personal lives.
Mr. Holland's Opus
This memorable movie gives all teachers hope that they truly have an impact on their students. Richard Dreyfuss is wonderful as a musician/composer who must take a teaching job to support his family. In the end, Dreyfuss' character realizes that he has had as much if not more of an impact from his teaching ashe would have as a composer.
小題1:The four films above are specially intended for_______.
A.studentsB.teachersC.parentsD.managers
小題2:Which film tells us that students not only need to learn knowledge in the books but also knowledge in life?
A.Mr. Holland's OpusB.The Karate Kid
C.To Sir With LoveD.The Miracle Worker
小題3:Which of the following statements is True according to the passage?
A.The actress who plays won a prize.
B.Richard Dreyfuss finally became a composer that he dreamt to be.
C.Helen Keller is the teacher of Annie Sullivan.
D.In the film “The Karate Kid” the teachers later have students do what they understand.

The evidence for harmony(和諧) may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image (形象)of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it had ever been in the past.“We were surprised by just how positive(肯定的) today’s young people seem to be about their families,” said one number of the research team.“They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds:they want a car and material goods,and they worry about whether school is serving them well. There’s more negotiation(商議) and discussion between parents and children,and children expect to take part in the family decision-making process. They don’t want to rock the boat(搗亂).”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel Lazall. “I always tell them when I‘m going out clubbing. As long as they know what I’m doing, they’re fine with me.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments(評(píng)論),“Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over. ”
小題1:What is the popular images of the teenager today?
A.They worry about school.
B.They dislike living with their parents.
C.They have to be locked in to avoid troubles.
D.They quarrel a lot with other family members.
小題2:The study shows that teenagers don’t want to __________.
A.share family responsibility
B.cause trouble in their families
C.go boating with their family
D.make family decisions
小題3:Compared with parents of 30 years ago, today’s parents ____________.
A.go to clubs more often with their children
B.a(chǎn)re much stricter with their children
C.care less about their children’s life
D.give their children more freedom
小題4:According to the writer, teenage rebellion __________.
A.may be a false belief
B.is common nowadays
C.existed only in the 1960s
D.resulted from changes in families
小題5:What is the passage mainly about?
A.Negotiation in family.

The UK has a well­respected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all, sometimes it can be confusing.
October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life.
However, having just left the comfort of home and all your friends behind, the prospect(前景)of meeting lots of strangers in big halls can be nerve­wracking(令人頭痛的). Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
Here is some top advice from past students on how to survive Freshers’ Week:
●Learn rules. Make sure you know British social etiquette(禮節(jié)). Have a few wine glasses and snacks handy for your housemates and friends.
●Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.
●Be sociable. The more active you are, the more likely you’ll be to meet new people than if you’re someone who never leaves their room.
●Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.
So with a bit of clever planning and effort, Freshers’ Week can give you a great start to your university life and soon you’ll be passing on your experience to next year’s new recruits
小題1:Which of the following statements is FALSE according to the passage?
A.October is generally the busiest month for universities.

A.coursesB.freshersC.neighborsD.challenges
小題3:We can infer from the 4th paragraph that    。
A.the newcomers usually miss the days living at home
B.most of the students in the UK spend three years in universities
C.many freshers are worried about how to fit university life
D.a(chǎn)ll the new students will make new friends and join certain clubs
小題4:Why does the author suggest having wine glasses and snacks handy?
A.To pass the busy university life.
B.To help make friends with other freshers.
C.To show yourself a drinker as others.

Steve, a twelve-year-old boy with alcoholic parents, was about to be lost forever, by the U.S. education system. Remarkably, he could read, yet, in spite of his reading skills, Steve was failing. He had been failing since first grade, as he was passed on from grade to grade. Steve was a big boy, looking more like a teenager than a twelve year old, yet, Steve went unnoticed... until Miss White.
Miss White was a smiling, young, beautiful redhead, and Steve was in love! For the first time in his young life, he couldn’t take his eyes off his teacher; yet, still he failed. He never did his homework, and he was always in trouble with Miss White. His heart would break under her sharp words, and when he was punished for failing to turn in his homework, he felt just miserable! Still, he did not study.
In the middle of the first semester of school, the entire seventh grade was tested for basic skills. Steve hurried through his tests, and continued to dream of other things, as the day wore on. His heart was not in school, but in the woods, where he often escaped alone, trying to shut out the sights, sounds and smells of his alcoholic home. No one checked on him to see if he was safe. No one knew he was gone, because no one was sober(清醒的) enough to care. Oddly, Steve never missed a day of school.
One day, Miss White’s impatient voice broke into his daydreams. “Steve!!” Startled, he turned to look at her.
“Pay attention!”
Steve locked his gaze on Miss White with adolescent adoration (青春期的愛(ài)慕), as she began to go over the test results for the seventh grade.
“You all did pretty well,” she told the class, “except for one boy, and it breaks my heart to tell you this, but...” She hesitated, pinning Steve to his seat with a sharp stare, her eyes searching his face.
“...The smartest boy in the seventh grade is failing my class!”
She just stared at Steve, as the class spun around for a good look. Steve dropped his eyes and carefully examined his fingertips.
 After that, it was war!! Steve still wouldn’t do his homework. Even as the punishments became more severe, he remained stubborn.
“Just try it! ONE WEEK!” He was unmoved.
“You’re smart enough! You’ll see a change!” Nothing fazed him.
“Give yourself a chance! Don’t give up on your life!” Nothing.
“Steve! Please! I care about you!”
Wow! Suddenly, Steve got it!! Someone cared about him? Someone, totally unattainable and perfect, CARED ABOUT HIM??!!
Steve went home from school, thoughtful, that afternoon. Walking into the house, he took one look around. Both parents were passed out, in various stages of undress, and the stench(惡臭) was overpowering! He, quickly, gathered up his camping gear, a jar of peanut butter, a loaf of bread, a bottle of water, and this time...his schoolbooks. Grim faced and determined, he headed for the woods.
The following Monday he arrived at school on time, and he waited for Miss White to enter the classroom. She walked in, all sparkle and smiles! God, she was beautiful! He yearned for her smile to turn on him. It did not.
Miss White, immediately, gave a quiz on the weekend homework. Steve hurried through the test, and was the first to hand in his paper. With a look of surprise, Miss White took his paper. Obviously puzzled, she began to look it over. Steve walked back to his desk, his heart pounding within his chest. As he sat down, he couldn’t resist another look at the lovely woman.
Miss White’s face was in total shock! She glanced up at Steve, then down, then up. Suddenly, her face broke into a radiant smile. The smartest boy in the seventh grade had just passed his first test!
From that moment nothing was the same for Steve. Life at home remained the same, but life still changed. He discovered that not only could he learn, but he was good at it!
He discovered that he could understand and retain knowledge, and that he could translate the things he learned into his own life. Steve began to excel! And he continued this course throughout his school life.
After high-school Steve enlisted in the Navy, and he had a successful military career. During that time, he met the love of his life, he raised a family, and he graduated from college Magna Cum Laude. During his Naval career, he inspired many young people, who without him, might not have believed in themselves. Steve began a second career after the Navy, and he continues to inspire others, as an adjunct professor(副教授) in a nearby college。
Miss White left a great legacy. She saved one boy who has changed many lives. I know, because I am the love of his life.
You see, it’s simple, really. A change took place within the heart of one boy, all because of one teacher, who cared.
小題1:What does the underlined sentence in the first paragraph mean?
A.Steve would give up schooling forever.
B.Steve was at a loss about improving his study.
C.Being unhappy both in school and at home, Steve intended to end his own life.
D.Due to his poor study, Steve was about to be expelled from his school.

For high school leavers starting out in the working world, it is very important to learn particular skills and practice how to behave in an interview or how to find all internship(實(shí)習(xí)). In some countries, schools have programs to help students onto the path to work. In the Unites States, however, such programs are still few and far between.
Research shows that if high schools provide career-related courses, students are likely to get higher earnings in later years. The students are more likely to stay in school, graduate and go on to higher education.
In Germany, students as young as 13 and 14 are expected to do internships. German companies work with schools to make sure that young people get the education they need for future employment.
But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world. Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track. Schwartz argued that this approach leaves the country’s most vulnerable(易受影響的)kids with no jobs and no skills.
Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high school. James Madison High School in New York, for example, encourages students to choose classes on career-based courses. The school then helps them gain on-the-job experience in those fields while they’re still at high school.
However, even for teens whose schools encourage them to connect with work, the job market is daunting. In the US, unemployment rates for 16-to 19-year-olds are above 20 percent for the third summer in a row.
“The risk is that if teenagers miss out on the Summer job experience, they become part of this generation of teens who had trouble in landing a job,”said Michael, a researcher in the US.
小題1:According to Robert Schwartz,_________.
A.there is no need for kids to go for higher education in the US
B.students should get contact with the working world at high school
C.education reform should focus on students’performance in exams
D.teenagers in the US can’t miss out on the summer job experience
小題2:What’s the main idea of the text?
A.Arguments about recent US education reform.
B.Tips on finding jobs for high school leavers.
C.The lack of career-based courses in US high schools.
D.Advice for American high school leavers.
