Can noncombustion (非燃烧) technology create a no-pollution way to drive?Imagine pulling into a service station to fuel up your car. But not at the gas pump or electric battery charger —at the air pump! That’s not hot air, either! The next generation of cars may run on thin air. Wouldn’t that be an incredible way to cut both pollution and dependence on foreign oil?
If you’ve ever inflated a balloon and then let it go, you’ve got the basics to test-drive the amazing MiniCAT, currently being developed by Noteur Development International (MDI), headquartered in Luxembourg. Invented by Formula One racing car designer Guy Negre, this experimental vehicle is unlike any car you’ve ever seen. While your family’s traditional car or SUV draws its horsepower using combustion, the only fuel that MiniCAT needs (CAT stands for Compressed Air Technology) is the air we breathe.
Start with about 25,000 gallons of air. Now, press it all into a space smaller than your school locker—because that’s the size of two super-strong, high-pressure air tanks, made from fiber and fixed beneath the air car. 
Confining that much air inside those small tanks generates an internal pressure of over 4,000 pounds per square inch. That’s over 300 times normal air pressure.
When this cold, high-pressure air enters MiniCAT’s unique engine, it interacts(交互作用) with warmer air to create pressure waves that pump the engine’s engineered pistons (活塞) to move the car. MiniCAT’s projected top speed is 60 miles per hour, with a range of 120 miles on a full air supply.
What is the passage mainly about?

A.Ways to cut down air pollution.
B.Cars that run on thin air.
C.Formula One racing car designer.
D.Dependence on foreign oil.

What is MiniCAT according to the passage?

A.The name of a car.
B.The name of a balloon.
C.The name of a car company.
D.The name of a car designer.

The underlined world “Confining” in Paragraph 4 can be replaced by ___________.

A.Keeping B.Preventing C.Pushing D.Running

What does the last paragraph tell us?

A.How much pressure the air creates.
B.How the car works.
C.What the normal air pressure is.
D.How the air gets into the engine.

[1] The health of our children and young people matters to us, and it matters to them. We should help them understand what makes and keeps them healthy and what to do when they have worries, are not feeling so good, or are simply ill.
[2] While health promotion, the process of enabling people to manage and improve their own health, plays a key role. a key significant and early point of private contact with health services for a teenager is their GP. While GPs continue to improve in terms of their confidence and ability to make a child patient feel comfortable, it is not yet a guaranteed good experience for teenagers—they may not alwayswhile talking to a doctor and some express feeling embarrassed while seeking advice from their GP
[3] Thus, two changes are required Firstly, better professional development. GPs do have some training in child development but it is not enough After all, learning how to talk to 12-18 year olds, and even more importantly, how to listen to what they have to say and encourage them to speak up; and to be confident that they understand what is said to them before they leave, takes time Secondly, we can include young people as the "teachers" here to help GPs learn how to interact effectively with their younger patients. GPs would benefit from feedback about their manners, the quality and simplicity of their communication and their way of explaining treatments and next steps - going beyond theory to learning by doing.
[4] In addition. children and young people are those with the time and energy to put into making our communities healthy. As enthusiastic learners, teenagers contribute through voluntary activities far more than adults and are deeply interested in the health services. And in doing so they are able to educate themselves in ways which can change lives.

Our lives were supposed to be more flexible and family-friendly thanks to the technology at our fingertips. But in this age of BlackBerrys, recession pressures, working at home after hours and on weekends, family time may not be working out the way we thought.
Busy parents who expected more time with the kids are Finding that more work hours at home don't necessarily translate into quality time with them.
A new generation of parents needs to discover the meaning of "quality time," researchers say. “Personally, just given the life I lead, I think there is something to this idea of quality time- spending productive time with children vs. just being around,” says Peter Brandon, a professor at Carleton College. He says engaging or interacting with a child in activities such as reading or playing counts as quality time rather than "passive monitoring," such as washing the dishes while the child is watching TV.
This time with children pays off,” Brandon says. He notes that good parent-child relationships result in children being happier and more successful, including at school.
As parents struggle to be more available to their kids, new research on work and family schedules to be presented Friday at the meeting in Dallas includes a study that shows parents' availability is on the decline because more parents are in the workforce. Although parents today may be spending more time on child care, they are less available overall.
Working parents who spend less time with their children should try to make sure the time they do spend is communicating with them, vs. doing the dishes or spending more time on themselves, Brandon says “The trade-off is not necessarily taking away time from your kid,” he says "You're taking away time from other things”
The first paragraph mainly intends to tell us that.

A.technology lets parents work at home
B.parents are satisfied with their work
C.technology makes our lives much easier
D.the family time is not always satisfying

We can learn from the third paragraph that.

A.some families are not experiencing quality time
B.it's enough for parents to stay with their children

D.working hours at home can transform into quality time

According to Brandon, the quality time means

A.just, being around with children
B.work time is separate from family time
C.spending instructive time with children
D.letting the children do whatever they want to do

The underlined sentence “This time with children pays” off means .

A.the time with children is of little value
B.the time with children costs quite a lot
C.the time with children leads to good result
D.the time with children has a bad effect on them

What will the author most probably talk about in next part of the passage?

A.How to spend more time at home
B.How to do the dishes in a proper way.
C.How to spend more time on working at home.
D.How to take away time in a much proper way.


While applying to college may seem easy, getting in can be tough! When you apply for college, you will have to be honest with yourself and do a bit of research to find the right fit. Here are three steps to take when applying to colleges for the best chances at getting into the best college for you.
Step l: Making A List Of Colleges To Apply To
With over 6,000 colleges in the United States, the first step in applying to college is to do some research and make a college list .This process will be different for everyone. The number of colleges you apply to can vary, from applying to 1 school (not recommended) to 30 schools (not recommended),each applicant can choose how many colleges they apply to. Many limit the number because applications are accompanied by a fee.
Step2: Splitting The List Into Target, Reach and Safety Schools
In general, students will want to apply to three types of schools: Target, Reach and Safety schools. It is up to you how many applications you send, but a good mix would be more target than reach, and at least one safety. You will need to take your list, and now decide which are your top picks, which are attainable for you academically, which are affordable for you only with aid, and refine your broad list into a group of schools that gives you the best chance for success. Talk to an admissions counselor at your high school if you have questions about this.
Step 3: Completing and Sending Applications to Colleges
Once your list is complete you are ready to apply to college by completing and sending in applications! College applications take time to complete —you have to write essays, ask for recommendations and get test scores sent to schools—so stay organized! All colleges will require these types of application materials, so start thinking about these items well before October or December. Once you complete and send them, then you have successfully applied to college.

Teenagers will be told to "stand up for their elders" on public transport — or risk losing their right to free travel.
London Mayor Boris Johnson will declare plans today to make youngsters sign a “courtesy pledge" (文明宣言) to promise to behave in a respectful manner when travelling in the capital. The three-point pledge states that they will give up their seats to the elderly, pregnant and disabled; keep from using offensive or threatening language; and be courteous and polite to fellow passengers and staff.
Those who refuse, or are caught behaving in a loutish manner, will have their free travel passes removed. The plan — a key part of Mr. Johnson's re-election bid— will initially affect the 400,000 ll-to-15-year-olds in London who qualify for free travel cards, but Tory sources believe the idea could be used across the country.
A Conservative insider said: "The plan corresponds perfectly with the push to create a Big Society. It is about changing culture and expectations around behavior to improve the atmosphere on buses and trains for everyone."
Speaking before today's launch, Mr. Johnson said he was determined to deal with the anti-social behavior of a "minority of youngsters" on public transport. "When I was a boy, I was taught to stand up for those less able to, "he said. "Youngsters enjoy the privilege of free travel, which is paid for by Londoners, but they have to understand that with that privilege comes responsibility. Anyone who abuses this privilege will have it taken away, and will have to earn that right bach ."
Teenagers found guilty of a serious violation of the new behavior rules will lose their travel passes, and will have to carry out unpaid community work to earn them back.
Mr. Johnson is also introducing a "two strikes and you're out" policy to deal with repeat offenders, under which those committing a second serious violation of the rules will lose their travel rights permanently.
Which of the following is NOT the content of the "courtesy pledge"?

A.Teenagers should give up their seats to the old.
B.Teenagers shouldn't talk with strangers in public.
C.Teenagers mustn't use aggressive language in public.
D.Teenagers must be polite to people on public transport.

A.rude B.stupid C.polite D.calm

According to Mr Johnson,____________.

A.youngsters should know duty comes with benefit

C.anyone shouldn't make money with the privilege
D.youngsters should do some unpaid community work

D.The "courtesy pledge” has been used across the country

In 1997, I found myself in a situation I never thought I'd be in: alone and begging for money in New York. My father had been separated from our family, and my mother had recently died from complications related to AIDS. What I remember most about such nights is lying on the cold marble floor and using my backpack for a pillow.
Even though I had lost my family, I made choices every single day to turn my life around. There was the haven for homeless teenagers called the Door, a non-profit organization that provided me with guidance, medical care and food, all of which kept me going while I completed my homework in train stations and under hallway lights. Perhaps the most surprising help though, I did not seek out﹔it found me. The New York Times told my story. In the weeks that followed, dozens of strangers reached out to me from all across the United States. At my high school, I began receiving handwritten letters of encouragement. Strangers showed up bearing clothes, books, and even hugs. Since the article mentioned I was applying to Harvard, one woman knitted a blanket for me. She attached this note to the box it was posted in: "It gets cold in those dorms. May you warm yourself knowing that people care about you".
With the help of these people, my life today bears no resemblance at all to my life then. I graduated not only from high school but also from Harvard University.
Before these people — some of them nameless— I just didn't realize how good people could be. But now I do, and I can say that the people who helped me have forever changed me. They are the reason behind my decision to join the board at the Door so that I can be part of a small team of people opening a high school for homeless teenagers .They are the reason I dedicate my life to opening pathways for others. And they are the reason I travel around the world helping people transform their own lives.
