If you live near a park，you've probably observed this unique squirrel behavior.As winter approaches，these creatures begin what looks like preparation for a wide scavenger（覓食）hunt.In great numbers，these squirrels begin to bury nuts!This kind of behavior raises a lot of questions for squirrel enthusiasts—the most pressing being how the squirrels find their nuts again.Eastern gray squirrels，in particular，bury their nuts far and wide.Scientists themselves aren't even quite sure of everything that goes into this hiding behavior，but they have some ideas.
For one，scientists have observed gray squirrels frequently burying and reburying their nuts.The scientists assumed that this behavior was to help always keep a fresh memory of the nuts!locations.However，it's not only memory that the squirrels need to combat（戰(zhàn)斗）in order to find their nuts!The gray squirrel community is rampant（猖獗的）with nut stealing.The squirrels can lose up to 25% of their hidden nuts to such thieves!Luckily，the squirrels have developed some clever methods to protect their nuts.Scientists have observed the squirrels creating false caches（儲藏）in order to trick thieves.If the squirrels are worried about thieves，they will also start to hide their nuts in difficult-to-reach places（like under bushes or in muddy areas）.
While it might be frustrating for squirrels to lose their carefully hidden nuts，it can be beneficial for other organisms.In particular，it can help the forest itself!A study done at the University of Richmond reports that squirrels fail to recover up to 74% of the nuts they bury.This misplacing of so many acorns （the seeds of oak trees），the study says，is likely responsible for oak forest regeneration.When squirrels misplace these buried acorns，they allow for these seeds to eventually grow into full oak trees!The squirrels' habit of widespread caching is also important to the growth of the forest，as it allows the genetic（基因的）information to spread far.
What seemed like a harmless scavenger hunt is actually part of an endless complex ecosystem in our forests!

1．Japan is a nation that appreciates the virtues of silence and good manners.Yet，when it comes to eating noodles，Japanese people can be the loudest in the world.
   According to lifestyle website Grapee.jye.ai，slurping （發(fā)出嘖嘖聲） when eating noodles is encouraged in Japanese culture.It's believed that taking air into your mouth can enhance （提高） the flavor of the noodles and help cool down the food.It's also considered to be a way to show appreciation for the dish.Sometimes，just making the noise alone seems to make the noodles more enjoyable.
   It was not until a new expression - "noodle harassment" -came out on social media that Japanese people started to realize the problem.They found that the slurping noise was making some foreign visitors uncomfortable.
   As a response，Japanese instant noodle maker Nissin introduced a so-called noise-canceling（降噪的） fork last month.The fork looks like an electric toothbrush.It is connected wirelessly to a smartphone.When the person using the fork starts to slurp，the fork will send a signal to the person's phone.Then the phone will play a sound to mask the slurping noise.
   But is it really necessary？Dining traditions and table manners do vary.In India，people eat with their hands.They think they build a connection with the food in this way.However，people who are used to eating with forks might find it unacceptable to get their hands covered in oil or sauce.But this eating method is part of India's culture，just like Japan's slurping is part of its own.
   "So，if you are eating noodles，please slurp as you like，" wrote a Japanese food blogger."If anyone gets annoyed while you are doing that，ignore them.They're missing the point entirely."

（1）Which of the following is NOT the reason for slurping when eating noodles，according to the text？

A．Cooling the noodles down.
B．Making the noodles more tasty.

D．Adding to the pleasure of eating noodles.
（2）What does the underlined word "harassment" mean in paragraph 3 mean？

A．Anxiety.
B．Annoyance.
C．Politeness.
D．Appreciation
（3）How does the noise-canceling fork work？

A．The fork removes the slurping noise.
B．The fork can be used as an electric toothbrush.
C．A smartphone reminds the user to stop slurping if a signal is sent to it.
D．A smartphone plays a sound to hide the noise when it receives a signal.
（4）Why does the author mention people in India in this passage？

A．To show that forks are unnecessary in Indian culture.
B．To give an example to show cultural difference are normal.
C．To show India has special dinning tradition and table manners.
D．To tell us the differences in eating habits between India and Japan.

3．The U.S.is still out in front of global competitors when it comes to innovation（革新），but American universities-where new ideas often spread-have reason to look over their shoulders.
   That's especially true for technologies like 5 G phone networks and artificial intelligence and they're exactly the fields where the U.S.has to lead-and also the ones where Asia，especially China，is catching up.Universities from China get more patents than their U.S.peers in wireless communications，according to research firm GreyB Services.In AI，17 of the top 20 universities and public research organizations are in China，with the Chinese Academy of Sciences topping the list，says the World Intellectual Property Organization in Geneva.
   There's a special place for universities in the development of science.Universities educate future scientists and can be incubators（孵化器）for pie-in-the-sky ideas-some of which turn out to be game-changers.The list ranges from search engines to DNA technology that's behind a whole industry of gene-manipulating（基因編輯）treatments.
   However，government aids to universities haven't been growing for more than a decade，meaning they've declined in real terms and as a share of the economy，leading to the cost increase for universities and meanwhile somehow discouraging the teaching staff from putting all their hearts into their scientific research.
   "If you look at the federal dollars，they've not really changed considerably，" says Stephen Susalka，head of AUTM，a technology transfer association whose members include 800 universities."Other countries are catching up.We can't be satisfied with what we have achieved."

.
A．Chinese universities have obtained more patents than other countries
B．the Chinese government provides aids to Chinese universities
C．wireless communications are changed dramatically these years
D．U.S.universities may lose their lead in some high-tech fields
（3）What is the main idea of Paragraph 3？

A．Universities can be birthplaces of game programmers.
B．Pie-in-the-sky ideas from universities can be revolutionary.
C．Universities play an important role in science development.
D．Gene-manipulation helps to develop DNA technology.
（4）What's Stephen Susalka's attitude towards the future development of U.S.universities？

A．Worried.
B．Disapproving.
C．Positive.
D．Unconcerned.
