When "Rise of the Planet of the Apes" was first shown to the public last month，a group of excited animal activists gathered on Hollywood Boulevard．But they weren't there to throw red paint on fur﹣coat﹣wearing film stars．Instead，one activist，dressed in a full﹣body monkey suit，had arrived with a sign praising the filmmakers："Thanks for not using real apes（猿）!"

The creative team behind "Apes" used motion﹣capture（动作捕捉）technology to create digitalized animals，spending tens of millions of dollars on technology that records an actor's performance and later processes it with computer graphics to create a final image（图象）．In this case，one of a realistic﹣looking ape．

Yet "Apes" is more exception than the rule．In fact，Hollywood has been hot on live animals lately．One nonprofit organization，which monitors the treatment of animals in filmed entertainment， is keeping tabs onmore than 2，000 productions this year．Already，a number of films，including "Water for Elephants，" "The Hangover Part Ⅱ" and "Zookeeper，" have drawn the anger of activists who say the creatures acting in them haven't been treated properly．

In some cases，it's not so much the treatment of the animals on set in the studio that has activists worried；it's the off﹣set training and living conditions that are raising concerns．And there are questions about the films made outside the States，which sometimes are not monitored as closely as productions filmed in the States．

（1）Why did the animal activists gather on Hollywood Boulevard？ 　　

A．	To see famous film stars．
B．	To oppose wearing fur coats．
C．	To raise money for animal protection．
D．	To express thanks to some filmmakers．

（2）What does paragraph 2 mainly talk about？ 　 　

A．	The cost of making "Apes．"
B．	The creation of digitalized apes．
C．	The publicity about "Apes．"
D．	The performance of real apes．

（3）What does the underlined phrase "keeping tabs on" in paragraph 3 probably mean？ 　　

A．	Listing completely．
B．	Directing professionally．
C．	Promoting successfully．
D．	Watching carefully．

（4）What can we infer from the last paragraph about animal actors？ 　　

A．	They may be badly treated．
B．	They should take further training．
C．	They could be traded illegally．
D．	They would lose popularity．

Emoji （表情符号） and Workplace Communication

In Asia， messaging platforms are growing rapidly， with users in the hundreds of millions，both at work and play．（1） 　　． It's been reported that 76 percent of employees in some western countries are using emojis at work．

Written communications can often read as cold and dull． Using emojis can add humor and feeling， keeping intention clear．（2） 　　， encouraging better and more frequent communication．

In any given office， employees can range from age 22 to 70 and beyond， and finding common ground in communication style can be a challenge．（3） 　　．While the younger generations prefer to communicate visually， for those used to working with traditional tools like email， it may feel like a learning curve （曲线）．The good news is that it's simple to learn and can be worth the effort．

There is also the matter of tone （语气）． Who hasn't received an email so annoying that it ruined an entire day？（4） 　 　．Emoji can help communication feel friendlier， and even a serious note can be softened with an encouraging smile．

（5） 　　，and emoji can contribute directly to that positive outcome． And when your employees begin adding smiling emojis to their business communication， you'll know you have succeeded in improving your work culture．

A．	Messages with emojis feel more conversational
B．	Even a formal email can seem cold and unfriendly
C．	Sending smiling faces to colleagues may seem strange
D．	The popularity of these platforms is spreading globally
E．	Giving employees the tools enables them to communicate honestly
F．	Studies show that friendlier communication leads to a happier workplace
G．	An easy way to bring all work generations together is with a chat platform

I have a special place in my heart for libraries．I have for as long as I can remember．I was always an enthusiastic reader，sometimes reading up to three books a day as a child．Stories were like air to me and while other kids played ball or went to parties，I lived out adventures through the books I checked out from the library．

My first job was working at the Ukiah Library when I was 16 years old． It was a dream job and I did everything from shelving books to reading to the children for story time．

As I grew older and became a mother， the library took on a new place and an added meaningin my life． I had several children and books were our main source （来源） of entertainment． It was a big deal for us to load up and go to the local library， where my kids could pick out books to read or books they wanted me to read to them．

I always read， using different voices， as though I were acting out the stories with my voice and they loved it! It was a special time to bond with my children and it filled them with the wonderment of books．

Now，I see my children taking their children to the library and I love that the excitement of going to the library lives on from generation to generation．

As a novelist， I've found a new relationship with libraries． I encourage readers to go to their local library when they can't afford to purchase a book． I see libraries as a safe haven （避风港）for readers and writers， a bridge that helps put together a reader with a book． Libraries， in their own way， help fight book piracy （盗版行为）and I think all writers should support libraries in a significant way when they can． Encourage readers to use the library． Share library announcements on your social media． Frequent them and talk about them when you can．

When you were trying to figure out what to buy for the environmentalist on your holiday list，fur probably didn't cross your mind．But some ecologists and fashion（时装）enthusiasts are trying to bring back the market for fur made from nutria（海狸鼠）．

Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles．"It sounds crazy to talk about guilt﹣free fur ﹣unless you understand that the nutria are destroying vast wetlands every year，" says Cree McCree，project director of Righteous Fur．

Scientists in Louisiana were so concerned that they decided to pay hunters ＄5 a tail．Some of the fur ends up in the fashion shows like the one in Brooklyn last month．

Nutria were brought there from Argentina by fur farmers and let go into the wild．"The ecosystem down there can't handle this non﹣native species（物种）．It's destroying the environment．It's them or us，" says Michael Massimi，an expert in this field．

The fur trade kept nutria in check for decades，but when the market for nutria collapsedin the late 1980s，the cat﹣sized animals multiplied like crazy．

Biologist Edmond Mouton runs the nutria control program for Louisiana．He says it's not easy to convince people that nutria fur is green，but he has no doubt about it．Hunters bring in more than 300，000 nutria tails a year，so part of Mouton's job these days is trying to promote fur．

Then there's Righteous Fur and its unusual fashions．Model Paige Morgan says，"To give people a guilt﹣free option that they can wear without someone throwing paint on them ﹣ I think that's going to be a massive thing，at least here in New York．" Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable．She's trying to come up with a label to attach to nutria fashions to show it is eco﹣friendly．

（1）What is the purpose of the fashion shows in New Orleans and Brooklyn？ 　　

A．	To promote guilt﹣free fur．
B．	To expand the fashion market．
C．	To introduce a new brand．
D．	To celebrate a winter holiday．

（2）Why are scientists concerned about nutria？ 　　

A．	Nutria damage the ecosystem seriously．
B．	Nutria are an endangered species．
C．	Nutria hurt local cat﹣sized animals．
D．	Nutria are illegally hunted．

（3）What does the underlined word "collapsed" in paragraph 5 probably mean？ 　　

A．	Boomed．
B．	Became mature．
C．	Remained stable．
D．	Crashed．

（4）What can we infer about wearing fur in New York according to Morgan？ 　 　

A．	It's formal．
B．	It's risky．
C．	It's harmful．
D．	It's traditional．

Some parents will buy any high﹣tech toy if they think it will help their child，but researchers said puzzles help children with math﹣related skills．

Psychologist Susan Levine，an expert on mathematics development in young children at the University of Chicago，found children who play with puzzles between ages 2 and 4 later develop better spatial skills．Puzzle play was found to be a significant predictor of cognition（认知）after controlling for differences in parents' income，education and the amount of parent talk，Levine said．

The researchers analyzed video recordings of 53 child﹣parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age．

"The children who played with puzzles performed better than those who did not，on tasks that assessed their ability to rotate（旋转）and translate shapes，" Levine said in a statement．

The parents were asked to interact with their children as they normally would， and about half of the children in the study played with puzzles at one time．Higher﹣income parents tended to have children play with puzzles more frequently，and both boys and girls who played with puzzles had better spatial skills．However，boys tended to play with more complex puzzles than girls，and the parents of boys provided more spatial language and were more active during puzzle play than the parents of girls．

The findings were published in the journal Developmental Science．

（1）In which aspect do children benefit from puzzle play？ 　 　

A．	Building confidence．
B．	Developing spatial skills．
C．	Learning self﹣control．
D．	Gaining high﹣tech knowledge．

（2）What did Levine take into consideration when designing her experiment？ 　　

A．	Parents' age．
B．	Children's imagination．
C．	Parents' education．
D．	Child﹣parent relationship．

（3）How do boys differ from girls in puzzle play？ 　　

A．	They play with puzzles more often．
B．	They tend to talk less during the game．
C．	They prefer to use more spatial language．
D．	They are likely to play with tougher puzzles．

（4）What is the text mainly about？ 　 　

A．	A mathematical method．

Today I tried cooking a simply dish myself．I like eating frying tomatoes with eggs，and I thought it must to be easy to cook．My mom told me how to preparing it．First I cut the tomatoes into pieces but put them aside．Next I broke the eggs into a bowl and beat them quickly with chopstick．After that I poured oil into a pan and turned off the stove．I waited patiently unless the oil was hot．Then I put the tomatoes and the beaten eggs into pan together．"Not that way，" my mom tried to stop us but failed．She was right．It didn't turn out as I had wished．

A Few Tips for Self﹣Acceptance

We all want it …to accept and love ourselves．But at times it seems too difficult and too far out of reach．（1） 　 　Here's a handful of ways that will set you in the right direction．

●（2） 　　Do not follow the people who make you feel not﹣good﹣enough．Why do you follow them？Are you hoping that eventually you will feel empowered because your life is better than theirs？Know that your life is your own；you are the only you in this world．

●Forgive yourself for mistakes that you have made．We are often ashamed of our shortcomings，our mistakes and our failures．（3） 　　You will make mistakes，time and time again．Rather than getting caught up in how you could have done better，why not offer yourself a compassionate （有同情心） response？"That didn't go as planned．But，I tried my best．"

●Recognize all of your strengths．Write them down in a journal．Begin to train your brain to look at strength before weakness．List all of your accomplishments and achievements．You have a job，earned your degree，and you got out of bed today．（4） 　　

●Now that you've listed your strengths，list your imperfections．Turn the page in your journal．Put into words why you feel unworthy，why you don't feel good enough．Now，read these words back to yourself．（5） 　　Turn to a page in your journal to your list of strengths and achievements．See how awesome you are？

A．	Feeling upset again？
B．	Where do you start？
C．	Nothing is too small to celebrate．
D．	Remember， you are only human．
E．	Set an intention for self﹣acceptance．
F．	Stop comparing yourself with others．
G．	When does the comparison game start？

The connection between people and plants has long been the subject of scientific research．Recent studies have found positive effects．A study conducted in Youngstown，Ohio，for example，discovered that greener areas of the city experienced less crime．In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants．

The engineers at the Massachusetts Institute of Technology（MIT） have taken it a step further ﹣ changing the actual composition of plants in order to get them to perform diverse，even unusual functions．These include plants that have sensors printed onto their leaves to show when they're short of water and a plant that can detect harmful chemicals in groundwater．"We're thinking about how we can engineer plants to replace functions of the things that we use every day，" explained Michael Strano，a professor of chemical engineering at MIT．

One of his latest projects has been to make plants glow（发光） in experiments using some common vegetables．Strano's team found that they could create a faint light for three﹣and﹣a﹣half hours．The light，about one﹣thousandth of the amount needed to read by，is just a start．The technology，Strano said，could one day be used to light the rooms or even to turn trees into self﹣powered street lamps．

In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a on﹣off treatment that would last the plant's lifetime．The engineers are also trying to develop an on and off "switch" where the glow would fade when exposed to daylight．

Lighting accounts for about 7% of the total electricity consumed in the US．Since lighting is often far removed from the power source（电源） ﹣ such as the distance from a power plant to street lamps on a remote highway ﹣ a lot of energy is lost during transmission（传输）．Glowing plants could reduce this distance and therefore help save energy．

（1）What is the first paragraph mainly about？ 　　

A．	A new study of different plants．
B．	A big fall in crime rates．
C．	Employees from various workplaces．
D．	Benefits from green plants．

（2）What is the function of the sensors printed on plant leaves by MIT engineers？ 　　

A．	To detect plants' lack of water．
B．	To change compositions of plants．
C．	To make the life of plants longer．
D．	To test chemicals in plants．

（3）What can we expect of the glowing plants in the future？ 　　

A．	They will speed up energy production．
B．	They may transmit electricity to the home．
C．	They might help reduce energy consumption．
D．	They could take the place of power plants．

（4）Which of the following can be the best title for the text？ 　　

A．	Can we grow more glowing plants？
B．	How do we live with glowing plants？
C．	Could glowing plants replace lamps？
D．	How are glowing plants made pollution﹣free？

Race walking shares many fitness benefits with running，research shows，while most likely contributing to fewer injuries．It does，however，have its own problem．

Race walkers are conditioned athletes．The longest track and field event at the Summer Olympics is the 50﹣kilometer race walk，which is about five miles longer than the marathon．But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact（接触）with the ground at all times．It's this strange form that makes race walking such an attractive activity，however，says Jaclyn Norberg，an assistant professor of exercise science at Salem State University in Salem，Mass．

Like running，race walking is physically demanding，she says．According to most calculations，race walkers moving at a pace of six miles per hour would burn about 800 calories（卡路里）per hour，which is approximately twice as many as they would burn walking，although fewer than running，which would probably burn about 1，000 or more calories per hour．

However，race walking does not pound the body as much as running does，Dr． Norberg says．According to her research，runners hit the ground with as much as four times their body weight per step，while race walkers，who do not leave the ground，create only about 1.4 times their body weight with each step．

As a result，she says，some of the injuries associated with running，such as runner's knee，are uncommon among race walkers．But the sport's strange form does place considerable stress on the ankles and hips，so people with a history of such injuries might want to be cautious in adopting the sport．In fact，anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique，she says．It takes some practice．

（1）Why are race walkers conditioned athletes？ 　　

A．	They must run long distances．
B．	They are qualified for the marathon．
C．	They have to follow special rules．
D．	They are good at swinging their legs．

（2）What advantage does race walking have over running？ 　　

A．	It's more popular at the Olympics．
B．	It's less challenging physically．
C．	It's more effective in body building．
D．	It's less likely to cause knee injuries．

（3）What is Dr． Norberg's suggestion for someone trying race walking？ 　　

A．	Getting experts' opinions．
B．	Having a medical checkup．
C．	Hiring an experienced coach．
D．	Doing regular exercises．

（4）Which word best describes the author's attitude to race walking？ 　 　

A．	Skeptical．
B．	Objective．
C．	Tolerant．
D．	Conservative．
