A kind of little cars may some day take the place of today’s ones. If everyone drives such cars in the future, there will be less pollution in the air. There will also be more space for parking cars in cities, and the streets will be less crowded. Three such cars can fit in the space now needed for one car of the usual size.
The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go only 65 kilometers an hour.
The cars of the future will be fine for getting around the city, but they will not be useful for long trips. Little cars will go 450 kilometers before needing to stop for more gasoline.
If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the gig, fast cars and other roads will be needed for the slower small ones.

My name is Chelsea Chowderhead. A chowder is a kind of soup. I was laughed at because of my last name as soon as I started school. So when my family moved to South Carolina, I asked my dad if I could change my name.

“You shouldn’t change who you are. Let people get to know you first and your name later. When you meet someone new, ask them a good question, something you’re really interested in. Once people start talking about themselves, they don’t judge(評價) you.”

Two days later I headed to my new school for the first day of class. At lunch, I noticed that there were twin brothers who were talking to each other. I remembered my dad’s advice, so I decided to try.

I noticed that their lunchboxes were identical. “What’s it like being a twin?” I asked.

They looked surprised. Then one said, “No one has ever asked us that!”

“Most of the time it’s good,” the other said. “When you’re a twin you always have someone to talk to and have lunch with.”

In no time we were laughing and talking. Then one of the brothers said, “I’m Nicholas, and this is my brother, Nathaniel. What’s your name?”

I took a deep breath and said, “I’m Chelsea Chowderhead.”

“Chowder? Like the soup?” asked Nathaniel.

“Yes,” I replied, looking down.

“Hey, cool! Do you want to come over after school and play basketball with us?” Nathaniel asked. I nodded.

And that is how I became friends with the twin brothers.

Since the beginning of time, man has been interested in the moon. The Romans designed a special day to show admiration and respect to the moon. They called it “Moonday”, or “Monday”, as we know it today. Later, the great mind of Leonardo da Vinci studied the moon and designed a machine to carry a human to the moon. Leonardo said that one day a great machine bird would take a person to the moon and bring great honor to the home where it was born. Four and a half centuries later, Leonardo’s idea was realized. Apollo II took three Americans, Collins, Aldrin, and Armstrong to the moon. The mission (任務(wù)) did fill the whole world with great surprise, as Leonardo had said it would. Numerous essays, articles, and books were written about man’s first moon mission. But perhaps the most interesting story was one written before the event over 100 years before. In 1865, French author Jules Verne wrote a story about the first journey to the moon. His story was very similar to the 1969 Apollo II mission. Verne’s spacecraft also contained three men—two Americans and a Frenchman. The spacecraft was described as being almost the same size as Apollo II. The launch (發(fā)射) site in Verne’s story was also in Florida. The spacecraft in Verne’s story was named the “Columbiad”. The Apollo II command ship was called “Columbia”. His account of sending the spacecraft into the space could easily have been written about how Apollo II was sent into the space.

1.Leonardo da Vinci said that a great machine bird would ________.

A．bring great honor to the moon

B．fly toward the sun

C．explore the heavens

D．take people to the moon

2.Jules Verne wrote his story of a man’s visit to the moon about ________.

A．100 years before the Apollo II mission

B．10 years before the Apollo II mission

C．four and one a half centuries ago

D．100 years ago

3.Verne’s story is very similar to _____.

A．the first U.S. space mission

B．the Apollo II mission

C．Leonardo da Vinci’s story

D．numerous other books on the same subject

4.The underlined word “spacecraft” probably means ________.

A．a(chǎn) kind of rocket                         B．a(chǎn) kind of plane

C．a(chǎn) kind of train                          D．a(chǎn) kind of bus

Removing the sleeve(封套), you will find a book that is entirely white, except for the names of its author and subject in elegant black type on the cover. It is the perfect design for the biography of a man who insisted that even the insides of his products be perfectly constructed, and that his factory wails flash in the whitest white.

The cover was the only part of the book Steve Jobs wanted to control, writes Isaacson in his introduction. Though Mr. Jobs pushed the biographer of Albert Einstein and Benjamin Franklin to write in his own way, generously allowing the writer more than 40 interviews, this book offers quite a different view of Mr. Jobs, who won much praise from his fans after his death on October 5th at the age of 56.

As a biographer of Albert Einstein and Benjamin Franklin, Mr. Isaacson knows how to celebrate long-dead genius, but he claimed that "Steve Jobs" would not be entirely praiseful words. The picture he paints, particularly in the first half of this book, is not nice. Mr. Jobs emerges as a controlling and often cold-blooded character. A child of the 1960s counter-culture (反主流文化), he hated, materialism and lived in simply furnished houses ( in part because he was too particular about furniture). But when Apple went public in 1980, he refused to give any share to Daniel Kottke, a Iongtime supporter and soul mate from college. "He has to abandon the people he is close to," observes Andy Hertzfeld, an early Apple engineer.

Mr. Jobs was undoubtedly possessing an extraordinary ability to attract others and inspire a kind of faith that could not be questioned. But also he could be cold and cruel. If he disapproved of an employee's work, he often shamed him. "This is who I am," he once said after being challenged,"and you can't expect me to be someone I'm not. " This disgusting personality wasn't always helpful,but it served a purpose, writes Mr. Isaacson, many would "end their chain of horror stories by saying that he got them to do things they never dreamed possible. "

Mr. Isaacson treats "Steve Jobs" as the biography of record, which means that it is a strange book to read so soon after its subject's death.   

1.The biography for Jobs is believed to have the perfect design because __

A．it follows Jobs' style

B．its cover is entirely white

C．black and white are his favorite .

D．it is designed by a famous biographer

2.The picture of Jobs that Isaacson paints in his book is __

①cruel    ②humorous   ③particular  ④generous

A．①③             B．②③             C．①④             D．③④

3.It can be safely concluded that        

A．Jobs is highly spoken of in the book

B．Isaacson doesn't think Jobs a good man

C．Jobs didn't care about the design of the book

D．a(chǎn)ll descriptions of Jobs are not nice in the book

4.This passage can be classified as          

A．a(chǎn) personal diary    B．a(chǎn) book review      C．a(chǎn) news report      D．a(chǎn) TV interview

Look closely at ,your hands-are they clean? It doesn't matter how many times you was  your hands. They're still crowded with microbes, which are also called "germs" or "bacteria". Microbes are everywhere. But don't worry-most microbes don't harm you. and many actually help you stay alive.

Now,  scientists say the microbes that live on our hands could be used in a surprising way: fighting crime.

When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal.  But according to a recent study, investigators could even use microbes to help break a criminal case.

Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody's hand is unique-much like one's fingerprint.

The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find.  And policemen use forensics such as studying fingerprints to identify the criminal.

"Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists.

"You can't sterilize(為……殺菌) a surface just by wiping it off. "

His team compared the bacteria on the hands of 273 people with the bacteria found on each person's computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son's hands matched the mix of microbes on that person's keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards.

But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful. 

Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool．

1.According to the passage,  microbes on people's hands_____

A．do more harm than good                 B．a(chǎn)re easy to get rid of

C．a(chǎn)re almost the same                     D．might help find crimes

2.The underlined word "forensics" in Paragraph 5 probably refers to________.

A．the scientific test used by police

B．a(chǎn) new kind of fingerprint

C．a(chǎn) kind of bacteria'in people's hands

D．a(chǎn) kind of newly invented keyboard

3.What did Fierer's team find through the study?

A．They found the criminal among the 237 people.

B．They could tell who had used which computer.

C．Computer keyboards couldn't keep people's microbe fingerprints.

D．People's characters could be identified by the keyboards they used.

4.We can learn from the passage that ______.

A．your microbes may give you away

B．scientists will come to a clear conclusion soon

C．many scientists think microbe fingerprints useless

D．the microbe fingerprint has been used in many cases

5.The main idea of the passage is about_____.

A．the importance of fingerprints             B．how to clean our hands

C．the usefulness of microbes                D．different germs on our hands
