Lots of people buy books and products from Amazon, an online seller. They offer and pay over the Internet and the books are shipped through the mail or a delivery service like FedEx.
One day, people could get their Amazon deliveries from an “unmanned aerial vehicle”—a timely vehicle that looks like a toy helicopter. And instead of waiting days to get the parcel, it could be at the buyer’s home in half an hour or less. The company is working on a fleet of tiny vehicles they call “Prime Air”. The vehicles are also known as “octocopters”. On their website, Amazon says, “One day, Prime Air Vehicles will be as normal as seeing a mail trucks on the road today.”
The U.S.’s Federal Aviation Administration (FAA) is working on safety regulations for unmanned flying vehicles like the Prime Air copters. Those regulations will make sure the copters are able to fly safely where they need to go. Once the FAA has put its rules in place, which could be as early as 2016, Amazon will be ready with its fleet of tiny flyers. The process could take as many as five years.
The new delivery service would likely be available only in the United States, at first. The copters the company is testing now can handle packages up to five pounds (2.3kg) and they have a range of 10 miles (16 kilometers).
Other companies are also looking at using unmanned flying vehicles to deliver their products. For instance, Domino’s Pizza in the U.K. released a video showing a “DomiCopter”, delivering a pizza. That video may have been a publicity stunt（噱頭）. In any case, just like Prime Air’s octocopters, the DomiCopters don’t have clearance（許可）to take off just yet.
1.For what purpose does Amazon want to use the Prime Air?
A. To predict the sales volume.
B. To check the delivery service.
C. To shorten the delivery period.
D. To remind people to order online.
2.What do we know from Amazon’s words in paragraph 2?
A. The Prime Air Vehicles will still travel on the road.
B. The Amazon’s delivery system needs to be improved.
C. The Prime Air Vehicles will be widely put into use soon.
D. The creation of the Prime Air Vehicles was inspired by the mail trucks.
3.The Prime Air Vehicles will be regulated by the U.S.’s FAA for __________.
A. the design plans
B. the delivery price
C. the driver’s training
D. the safety assessment
4.What does Paragraph 4 mainly tell us about the new delivery method?
A. Its safety B. Its delivery ability
C. Its appearance D. Its moving speed
5.What can be inferred from the last paragraph?
A. The new delivery service has attracted more customers.
B. The designer of Amazon has promoted “Prime Air” to other company.
C. Another unmanned vehicle has been put into use by a British pizza company.
D. Unmanned vehicles could possibly be developed and employed by more companies.

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on well with their parents, which is the opposite of the popularly held image 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 happier than it has ever been in the past. “We were surprised by just how positive today’s young people seem to be about their families,” said one member 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 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.”
So it seems that these parents are 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 LaSalle. “I always tell them when I'm going out clubbing. When they know what I'm doing, they’re fine with it.” Susan Cromer, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call talk or discussion. For example, when I’d done all my homework, I 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 based on real facts. A researcher explains, “Teenagers were thought to be different from others in a part of time in our social history. But to our surprise, they say they are getting on well with their parents. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled.”
1.The study shows that teenagers don't want to ______________________.
A. share family duties
B. cause trouble in their families
C. go boating with their family
D. make family decisions
2.Compared with parents of 30 years ago, today’s parents ___________________.
A. go to clubs more often with their children
B. are much stricter with their children
C. care less about their children’s life
D. give their children more freedom
3.According to the writer, teenage rebellion ____________________.
A. may be a wrong opinion
B. is common at present
C. always happened in the 1960s
D. was caused by changes in families
4.Which title best gives the main idea of the passage?
A. Discussion in family
B. Teenage education in family
C. Teenage trouble in family
D. Harmony in family

Two recent studies have found that punishment is not the best way to influence behavior.
One showed that adults are much more cooperative if they work in a system based on rewards. Researchers at Harvard University in the United States and the Stockholm School of Economics in Sweden did the study.
They had about two hundred college students play a version of the game known as the Prisoner’s Dilemma. The game is based on the tension between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players. Harvard researcher David Rand says the most successful behavior proved to be cooperation. The groups that rewarded the most earned about twice as much in the game as the groups that rewarded the least. And the more a group punished itself, the lower its earnings. The study appeared last month in the journal Science.
The other study involved children. It was presented last month in California at a conference on violence and abuse. Researchers used intelligence tests given to two groups. More than eight hundred children were aged two to four the first time they were tested. More than seven hundred children were aged five to nine. The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishment and children whose parents did not.
The study says the IQs of the younger children who were not spanked were five points higher than those who were. In the older group, the difference was almost three points. The more they are spanked, the slower their mental development.
1.Which of the following is TRUE according to the second study?
A. Children’s IQs have much to do with physical punishment.
B. The study is about violence and cooperation of children.
C. The children tested were divided into groups of four.
D. Children’s mental development only relies on their IQs.
2. What does the underlined word “spanked” refer to?
A. punished B. blamed C. tested D. praised
3.What might be the best title for the text?
A. The Best Way to Correct Misbehavior
B. Punishment Is the Best Way of Education
C. Cooperation Is the Most Successful Behavior
D. Punishment or Reward: Which Works Better on Behavior?

Louis Armstrong had two famous nicknames (綽號). Some people called him Bagamo. They said his mouth looked like a large bag. Musicians often called him Pops, as a sign of respect for his influence on the world of music.
Born in 1901 in New Orleans, he grew up poor, but lived among great musicians. Jazz was invented in the city a few years before his birth. Armstrong often said, “Jazz and I grew up together.”
Armstrong showed a great talent for music when he was taught to play the cornet (短號) at a boy’s home. In his late teens, Armstrong began to live the life of a musician. He played in parades, clubs, and on the steamboats that traveled on the Mississippi River. At that time, New Orleans was famous for the new music of jazz and was home to many great musicians. Armstrong learned from the older musicians and soon became respected as their equal. In 1922 he went to Chicago. There, the tale of Louis Armstrong begins. From then until the end of his life, Armstrong was celebrated and loved wherever he went. Armstrong had no equal when it came to playing the American popular song.
His cornet playing had a deep humanity (仁愛) and warmth that caused many listeners to say, “Listening to Pops just makes you feel good all over.” He was the father of the jazz style and also one of the best-known and most admired people in the world. His death, on July 6, 1971, was headline news around the world.

A. looked like a musician
