4．See a cellphone cover that you like on Taobao？Forget about placing an order，paying the bill online and waiting for days for it to be delivered to you．In the near future，you'll be able to get it in minutes just by hitting"print"on your computer．
　  You might find it hard to believe that you could actually"print"an object like you would a picture．But it is not that hard to understand how it would work．Just as a traditional printer sprays （喷） ink onto paper line by line，modern 3D printers spread material onto a surface layer by layer，from the bottom to the top，gradually building up a shape．
　  Instead of ink，the materials the 3D printer uses are mainly plastic，resin（树脂） and certain metals．The thinner each layer is-from a millimetre to less than the width of a hair-the smoother and finer the object will be．
　  This may sound like a completely new technology，but the truth is that 3D printing has been around since the late 1980s．Back then，it was barely affordable for most people，so few knew about it．
    Last year，though，saw a big change in the 3D printing industry-printers became much cheaper．For example，10 years ago a desktop 3D printer might have cost￡20，000，while now they cost only about￡1，000，accordin g to the BBC．
    Taken out of the factory and introduced to more diverse and common uses，3D printing can create just about anything you can think of-flutes （笛子），bikinis，jewelry，aircraft parts and even human organs．In fact，scientists from Cornell University in New York have just made an artificial ear using a 3D printer，according to Science Daily．The fake ear looks and acts exactly like a natural one．
    However，as 3D printing becomes more common，it may bring about certain problems-such as piracy．"Once you can download a coffee maker，or print out a new set of kitchen utensils （餐具） on your personal 3D printer，who will visit a retail （零售的） store again？"an expert in 3D printing told Forbes News．Even more frightening，what if anyone in the world could use a 3D printer to print out a fully functioning gun？
32．According to the article，in the future，the 3D printing technology willB．
A．enable people to make better purchases online
B．change the way we make many products
C．be applied as widely in our daily life as computers
D．shorten the time it takes for people to get what they buy online
33．What happened in the 3D printing industry last year？D
A．The 3D printing technology was taken out of the factory．
B．The 3D printing technology began to be used in various fields．
C．The 3D printer was used for medical treatment for the first time．
D．The 3D printer became more afforda ble for consumers．
34．How is the last paragraph developed？A
A．By giving examples．
B．By making comparisons．
C．By analyzing the cause and effect．
D．By presenting research findings．
35．What is the best title of the passage？D

B．Technology in the Future
C．Online Shopping Disappearing　　         
D．Printing out Everything．

3．Being Authoritative （由权威的） ParentsPhrases like"tiger mom"and‘‘helicopter parent"have made their way into everyday language．Many of us find ourselves drawn to the idea that with just a bit more parental hard work and effort，we might turn out children with bright futures．But is there anything wrong with a kind of"overparenting style"？
Parental involvement has a long history of being studied．Many of the studies，conducted by Diana Baumrind，a famous psychologist at the University of California，Berkeley，have found that a good parent is the one who is involved and reacts to her child in a positive way，who sets high expectations but gives her child independence．These"authoritative parents"appear to hit the sweet spot of parental involvement and generally raise children who do better academically，psychologically and socially than children whose parents are not strict and less involved，or controlling and more involved．Why is this parenting style so successful？
Authoritative parents actually help improve motivation in their children．Carol Dweck，a social psychologist at Stanford University，has done research that indicates why authoritative parents raise more motivated children．In a typical experiment，Dr．Dweck takes young children into a room and asks them to solve a simple puzzle．Most do so with little difficulty．But then Dr．Dweck tells some，but not all，of the kids how clever they are．As it turns out，the children who are not told they're smart are more motivated to solve increasingly difficult puzzles．They also show higher levels of confidence and show greater progress in puzzle-solving．
As the experiment suggests，praising children's talents and abilities seems to shake their confidence．Dealing with more difficult puzzles carries the risk of losing one's status as"smart"．Dr．Dweck's work strongly supports that of Dr．Baumrind，who also found that reasonably supporting a child's independence and limiting interference （干涉） causes better academic and emotional results．
The central task of growing up is to develop a sense of self that is independent and confident．If you treat your young child who is just learning to walk as if she can't walk，you reduce her confidence．Allowing children to make mistakes is one of the greatest challenges of parenting．It is easier when they are young．The potential mistakes carry greater risks，and part of being a parent is reducing risk for our children．
24．According to the passage，a"tiger mom"D．
A．helps her children realize their dreams      
B．speaks her children's everyday language
C．places reasonable expectations on her children   
D．pays close attention to her children's experiences
25．It is implied that controlling style of parenting mayC．
A．face more challenges of children         
B．foster independence in children
C．cause more problems in children              
D．lead to children's academic success
26．The example of the children doing the puzzles suggests thatB．
A．a good game plays a big role in training young minds
B．overpraising makes children less motivated a nd confident
C．puzzle-solving can give children the motivation they need
D．bright children usually show less confidence in difficult games
27．The last paragraph tells us thatC．
A．children should not be given much freedom
B．parents should not increase the risk of challenging
C．parents should allow their children to learn from mistakes
D．children should correct mistakes with the help of their parents．

2．Learning About Different Cultures
Most of us live in a multicultural surroundings these days．Culture can bring us together，but it can also be a cause of division．How does our own culture affect the way we view others？What steps can we take to minimize problems？
Once my friend，who is of Greek origin，went to Sweden on business．He was sent by the head office in the US to introduce a new computer program to their branch office in Sweden．This newly created software would cut production cost in half and speed up the time from planning to production by 30percent，as well as make the finished product look better．After presenting this program to the managers and directors，he waited for their feedback．At first it was quiet．Then，the general manager said，"Hmm，this looks good．"in a flat voice．"Hmm，I agree，"said another．My friend was in shock．Later on，when he told this to me，he said，"My mother used expressions such as‘Fabulous!'and‘Marvelous!'．These people were presented with a multibillion-dollar program，and all they could say was"Hmm．Good．I don't understand it!"
What was the problem？Culture．What is an acceptable way of expressing excitement and joy in one country is not the same in another．The Swedes were thrilled，and they thought it was a fantastic computer program．They just had a different way of showing it．
Another example：I remember my mother always telling me to look at her when she was talking to me，especially if it was something important．It was a way of showing that I was paying attention in a respectful way．Now，my friend from Nigeria told me that she never allows her children to look at her when she is talking．"I want them to respect me，"she says．Who is right？Both．That's the beauty of culture．There is no such thing as right or wrong，good or bad culture．
Of course，one has to take into consideration people living nearby．It is true that a person has to adjust to the country where he chooses to live．On the other hand，when people move into our country，we can make an effort to get to know their culture．Ask them about their country； ask them why they do certain things or wear different clothes．It can be quite interesting，actually．This doesn't mean we have to like it，or live our lives in their way．But knowledge can definitely lead to fewer disagreements and more understanding between people．
When culture is understood and used in an appropriate way，it can give a person a feeling of belonging and security．You know what to do in different situations．For example：at the time of birth and death．Let's give place to culture．Try to know and understand other people's culture，and also try to analyze our own．Let's choose our own way of life．Above all else---let's live in peace with all men!

1．You either have it or you don't一a sense of direction，that is．But why could some people find their way across the Sahara without a map，while others can lose themselves in the next street
Scientists say we're all born with a sense of direction，but it is not properly understood how it works．One theory is that people with a good sense of direction have simply worked harder at developing it．Research being carried out at Liverpool University supports this idea and suggests that if we don't use it，we lose it．"Children as young as seven have the ability to find their way around，"says J im Martland，research director of the project．"However，if they are not allowed out alone or are taken everywhere by car，they never develop the skills．"
Jim Martland also says that young people should be taught certain skills to improve their sense of direction．He makes the following suggestions：
If you are using a map，turn it so it relates to the way you are facing．
If you leave your bike in a strange place，put it near something like a big stone or tree．Note landmarks（路标）on the route as you go away from your bike．When you return，go back along the same route．
Simplify（简化）the way of finding your direction by using lines such as streets in a town，streams，or walls in the countryside to guide you．Count your steps so that you know how far you have gone and note any landmarks such as hills which can help to find out where you are．
Now you will never get lost again!

D．remember your route by looking out for steps and stairs．

20．My parents were in a huge argument，and I was really upset about it．I didn't know who I should talk with about how I was feeling．So I asked Mom to allow me to stay the night at my best friend's house．Though I knew I wouldn't tell her about my parents'situation，I was looking forward to getting out of the house．I was in the middle of packing up my things when suddenly the power went out in the neighborhood．Mom came to tell me that I should stay with my grandpa until the power came back on．
I was really disappointed because I felt that we did not have much to talk about．But I knew he would be frightened alone in the dark．I went to his room and told him that I'd stay with him until the power was restored．He was quite happy and said，"Great opportunity．"
"What is it？"I asked．
"To talk，you and I"he said．"To hold a private little meeting about what we're going to do with your mom and dad，and what we're going to do with ourselves now that we're in the situation we are in．"
"But we can't do anything about it．Grandpa，"I said，surprised that here was someone with whom I could share my feelings and someone who was in the same"boat"as I was．
And that's how the most unbelievable friendship between my grandfather and me started．Sitting in the dark，we talked about our feelings and fears of life-from how fast things change，to how they sometimes don't change fast enough．That night，because the power went out，I found a new friend，with whom I could safely talk about all my fears and pains，whatever they may be．Suddenly，the lights all came back on．"Well，"he said，"I guess that means you'll want to go now．I really like our talk．I hope the power will go out every few nights!"

18．（节日里）整个国度到处是盛开的樱花，看上去就像是覆盖了一层粉红色的雪．
The country，covered with cherry tree flowers，looksasif （though）it is covered with pink snow．

17．Nowadays parents and their children are spending less and less time communicating with each other．（31）G．It is reported that American parents today spend about 40percent less time with their children than parents did a generation ago．To keep your family time creative and enjoyable，below is a list of helpful family time tips．
1．Eat together & listen to each other
Most children today don't know the meaning of a family dinnertime．Yet the communication and unity built during this time is necessary to a healthy family life．Sharing a meal together allows parents and their children the opportunity to talk about each other's lives．（32）F．
2．Read often
It's important for parents to read to their children．The latest research shows that reading to your children develops an interest in knowledge and contributes to language development．It also increases their concentration on things and helps them become more curious．（33）D．After reading，ask questions about what the books are about．
3．Start a hobby or project
Choose a fun activity that your children are interested in．Activities like cooking，fishing or biking can be their great hobbies．（34）B．Once a child learns a new skill，let him or her take the lead under your direction．
4．Plan a family outing
（35）C．Jump into the family car and go for a drive．Prepare a picnic lunch and visit a local park．Take time to play or ride a bike．A slow and relaxing walk in the woods will help parents communicate with their children better．Also，a visit to the zoo or museum will inspire enthusiasm in a child and lead to long discussions．

A．It is very important for children to exercise．
B．They can open the door to exciting family time．
C．Sometimes getting out of the house is important．
D．Look for books that your children would enjoy reading．
E．New technology has made video games more popular with children．
F．This is also a time for parents to listen and give advice to their children．
G．As a result，many children are getting less love than their parents once got．

16．Many people think that the most popular way of communicating with other people is through the mouth．But what they don't know is that actual communication using mouth accounts for only around 10% （or even less） of all the means to communicate a message．
Moreover，you can never determine the honesty of people by what they say alone．In fact，words expressed through mouth do not reflect what people really think or feel．The only way you can determine their true inner feelings and thoughts is by reading their body language．
Have you ever wondered what it would be like if you can"see through"the emotions of other people？For example，you ask a person if he can do an important task．He says"OK"．But deep inside，you are questioning yourself，"Is he really willing to do this job？"or"Does he have the confidence to finish this task？"You can't question him directly because that would be like belittling  him．And even if you ask him those questions，his replies will not tell you what he really feels or thinks．
Then what is the final solution？Here are just a few of the magic tricks you're about to discover：
◆Actions to make someone like or trust you．
◆How to win in a negotiation（谈判）．
◆How to attract the opposite sex using body language．
◆How to increase your sales using body language．
◆How to help you find out who is telling a lie．
And a lot，lot more!
Body language is very easy and fun to learn．With this book，you will make body movements to achieve the success you've always longed for．Do yourself a big favor and get a copy of Body Language Magic．

D．to tell us something about true inner feelings．

15．If you have ever been discouraged because of failure，please read on．Usually，achieving what you set out to do is not the important thing．Let me explain．
Two brothers decided to dig a deep hole behind their house．As they were working，several older boys stopped by to watch．
"What are you doing？"asked one of the visitors．
"We plan to dig a hole all the way through the earth!"one of the brothers answered excitedly．
The older boys began to laugh，telling the younger ones that digging a hole all the way through the earth was impossible．After a long silence，one of the diggers picked up a bottle full of spiders and insects．He removed the lid（盖子） and showed the wonderful contents to the visitors who were laughing at them．Then he said quietly and confidently，"Even if we don't dig all the way through the earth，look at what we found along the way!"
Their goal was far too difficult，but it made them big．And that is what a goal is for-to make us move in the direction we have chosen．In other words，it sets us digging!
But not every goal will be fully achieved．Not every job will end successfully．Not every hope will come to pass．Not every love will last．But when you fall short of your aim，perhaps you can say，"Yes，but look at what I found along the way!Look at the wonderful things which have come into my life because I tried to do something!"And I believe it is the joy in the journey，in the end，that truly matters．
