1．I was in the garden with Augie，my grandson，watching the bees． "How do they make honey？" Augie asked． "Actually，Augie，I don't know，" I replied． "But，Grandma，you have your phone，" he said．For Augie，holding a smartphone almost means knowing everything．
During my childhood I was crazy about books．Over time，reading hijacked my brain，as large areas once processing the real world adapted to processing the printed word．As far as I can tell，this early immersion （沉浸） didn't prevent my development．
Many parents worry that "screen time" will damage children's development，but recent research suggests that most of the common fears about children and screens are unfounded．There is one exception：looking at screens before bed really disturbs sleep，in people of all ages．The American Academy of Pediatrics（AAP） used to recommend strict restrictions on screen exposure．Last year，the organization examined the relevant science more thoroughly and changed its recommendations．The new guidelines stress that what matters is what children watch and with whom．
New tools have always led to panic guesses．The novel，the telephone，and the television were all declared to be the End of Civilization，particularly in the hands of the young．Part of the reason may be that adult brains require a lot of focus and effort to learn something new，while children's brains are designed to master new environments naturally．New technologies always seem disturbing to the adults attempting to master them，while attractive to those children like Augie．
When Augie's father got home，Augie rushed to meet him and said in excitement． "Daddy，Daddy，look，" he said，reaching for my phone． "Do you know how bees make honey？I'll show you…"
（1）Which of the following can best replace the underlined word "hijacked" in Paragraph 2？
A．occupied．
B．damaged．
C．improved．
D．relaxed．
（2）What do the new guidelines of AAP focus on about "screen time"？
A．The harm to children．
B．The content and context．
C．Children's sleep．
D．People's fears．
（3）What might be the author's attitude towards "screen time"？
A．Opposed．
B．Doubtful．
C．Disappointed．
D．Favorable．
（4）What can be inferred from the last paragraph？
A．Augie's father might get angry for Augie used a phone．
B．Augie asked his father about how bees make honey．
C．Augie's father didn't know how to answer Augie's question．
D．Augie was excited to know new knowledge through the smart phone．組卷：7引用：1難度：0.5 -
2．There's a new frontier in 3 D printing that's beginning to come into focus：food．Recent development has made possible machines that print，cook，and serve foods on a mass scale．And the industry isn't stopping there．
Food production
With a 3 D printer，a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake．Not everybody can do that - it takes years of experience，but a printer makes it easy．A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same，" freeing cooks to complete other tasks．In another restaurant，all of the dishes and desserts it serves are 3 D-printed，rather than farm to table．
Sustainability（可持續(xù)性）
The global population is expected to grow to 9.6 billion by 2050，and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels．Sustainability is becoming a necessity．3 D food printing could probably contribute to the solution．Some experts believe printers could use hydrocolloids （水解膠體） from plentiful renewables like algae（藻類）and grass to replace the familiar ingredients（烹飪?cè)希? D printing can reduce fuel use and emissions．Grocery stores of the future might stock "food" that lasts years on end，freeing up shelf space and reducing transportation and storage requirements．
Nutrition
Future 3 D food printers could make processed food healthier．Hod Lipson，a professor at Columbia University，said，"Food printing could allow consumers to print food with customized nutritional content，like vitamins．So instead of eating a piece of yesterday's bread from the supermarket，you'd eat something baked just for you on demand．"
Challenges
Despite recent advancements in 3 D food printing，the industry has many challenges to overcome．Currently，most ingredients must be changed to a paste（糊狀物） before a printer can use them，and the printing process is quite time-consuming，because ingredients interact with each other in very complex ways．On top of that，most of the 3 D food printers now are restricted to dry ingredients，because meat and milk products may easily go bad．Some experts are skeptical about 3 D food printers，believing they are better suited for fast food restaurants than homes and high-end restaurants．
（1）What benefit does 3 D printing bring to food production？
A．It helps cooks to create new dishes．
B．It saves time and effort in cooking．
C．It improves the cooking conditions．
D．It contributes to restaurant decorations．
（2）What can we learn about 3 D food printing from Paragraphs 3？
A．It solves food shortages easily．
B．It quickens the transportation of food．
C．It needs no space for the storage of food．
D．It uses renewable materials as sources of food．
（3）According to Paragraph 4，3 D-printed food．
A．is more available to consumers
B．can meet individual nutritional needs
C．is more tasty than food in supermarkets
D．can keep all the nutrition in raw materials
（4）What is the main factor that prevents 3 D food printing from spreading widely？
A．The printing process is complicated．
B．3 D food printers are too expensive．
C．Food materials have to be dry．
D．Some experts doubt 3 D food printing．組卷：3引用：1難度：0.6 -
3．Why You Should Celebrate Your Mistakes
When you make a mistake，big or small，cherish（珍視） it like it's the most precious thing in the world，because in some ways，it is．
Most of us feel bad when we make mistakes，beat ourselves up about it，feel like failures，get mad at ourselves．
And that's only natural：most of us have been taught from a young age that mistakes are bad，that we should try to avoid mistakes．We've been scolded when we make mistakes at home，school and work．Maybe not always，but probably enough times to make feeling bad about mistakes an unconscious reaction．
Yet without mistakes，we could not learn or grow．If you think about it that way，mistakes should be cherished and celebrated for being one of the most amazing things in the world：they make learning possible；they make growth and improvement possible．
By trial and error-trying things，making mistakes，and learning from those mistakes-we have figured out how to make electric light，to paint the ceiling of the Sistine Chapel，to fly．
Mistakes make walking possible for the smallest toddler，make speech possible，make works of genius possible．
Think about how we learn：we don't just consume information about something and instantly know it or know how to do it．You don't just read about painting，or writing，or computer programming，or baking，or playing the piano，and know how to do them right away．Instead，you get information about something，from reading or from another person or from observing usually…then you construct a model in your mind…then you test it out by trying it in the real world…then you make mistakes…then you revise the model based on the results of your real-world experimentation and repeat，making mistakes，learning from those mistakes，until you've pretty much learned how to do something．That's how we learn as babies and toddlers，and how we learn as adults．Mistakes are how we learn to do something new，because if you succeed in something，it's probably something you already knew how to do．You haven't really grown much from that success---at most it's the last step on your journey，not the whole journey．Most of the journey was made up of mistakes，if it's a good journey．
So if you value learning，if you value growing and improving，then you should value mistakes．They are amazing things that make a world of brilliance possible．
（1）Why do most of us feel bad about making mistakes？
A．Because mistakes make us suffer a lot．
B．Because it's a natural part in our life．
C．Because we've been taught so from a young age．
D．Because mistakes have ruined many people's careers．
（2）According to the passage，what is the right attitude to mistakes？
A．We should try to avoid making mistakes．
B．We should owe great inventions mainly to mistakes．
C．We should treat mistakes as good chances to learn．
D．We should make feeling bad about mistakes an unconscious reaction．
（3）The underlined word "toddler" in Paragraph 6 probably means．
A．a(chǎn) small child learning to walk
B．a(chǎn) kindergarten child learning to draw
C．a(chǎn) primary school pupil learning to read
D．a(chǎn) school teenager learning to write
（4）We can learn from the passage that．
A．most of us can really grow from success
B．growing and improving are based on mistakes
C．we learn to make mistakes by trial and error
D．we read about something and know how to do it right away組卷：39引用：2難度：0.7

"I'm going to miss you so much， Poppy，" said the tall， thin teenager． He bent down to hug his old friend goodbye． He stood up， hugged his parents， and smiled， trying not to let his emotions（情緒）get the better of him．
His parents were not quite able to keep theirs under control． They had driven their son several hours out of town to the university where he would soon be living and studying． It was time to say goodbye for now at least． The family hugged and smiled through misty eyes and then laughed．
The boy lifted the last bag onto his shoulder， and flashed a bright smile． "I guess this is it，" he said． "I'll see you back home in a month， okay？" His parents nodded， and they watched as he walked out of sight into the crowds of hundreds of students and parents． The boy's mother turned to the dog， "Okay， Poppy， time to go back home．"
The house seemed quiet as a tomb without the boy living there． All that week， Poppy didn't seem interested in her dinner， her favorite toy， or even in her daily walk． Her owners were sad too， but they knew their son would be back to visit． Poppy didn't．
They offered the dog some of her favorite peanut butter treats． They even let her sit on the sofa， but the old girl just wasn't her usual cheerful self． Her owners started to get worried． "What should we do to cheer Poppy up？" asked Dad． "We've tried everything．"
"I have an idea，but it might be a little crazy，" smiled Mom． "Without anybody left in the house but us， this place could use a bit of fun． Let's get a little dog for Poppy．"
It didn't take long before they walked through the front door carrying a big box． Poppy welcomed them home as usual， but when she saw the box， she stopped． She put her nose on it． Her tail began wagging（擺動(dòng)）ever so slowly， then faster as she caught the smell．
