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(chǔ)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．Growing more food to feed the world will require more people to work in agriculture.According to the National FFA Organization，we need to produce as much food as possible in the next 40 years because of the growth in population.
   Indiana remains pivotal to meeting this need.Indiana is one of the nation's most productive states in producing tomatoes，corn，soybeans，ducks，chickens and eggs.At snack time，Indiana ranks second in growing popcorn and making ice cream.
   The Indiana Business Research Center reports that agriculture contributes at least ＄25 billion to the state's economy，which creates more career opportunities for young people. "There are more than 300 careers in
agriculture，" said Joshua Bledsoe，the FFA advisor. "It starts with the farm in agricultural production，but then all the way to the plate there are tons of career opportunities once the product has left the farm.Therefore，we need folks who will understand processing and food science.We also need people in marketing and communications as well as folks in law."
   Including skills in computer technology，Beck's Hybrids is the nation's largest family-owned seed company.Bruce Kettler，the former director of public relations for the company，explained that technology is important to the company's development.For example，computer technology on tractors（拖拉機(jī)）allows farmers to follow the exact same pathway across the farm field throughout the season，from planting to harvesting and all steps in between.
   Indiana is enjoying a harvest season，and even larger harvests will be needed to satisfy the world's increasing need for food.The amount of land used for farming has decreased by at least 25 percent since 1950.Therefore，growing more food will require more technology and more people.As Bledsoe put it，"You are going into the global workforce when you go into agriculture，and the opportunities are endless."

（1）What does the underlined word "pivotal" mean？

A．Doubtful.
B．Vital.
C．Equal.

B．Producing food is of great importance.
C．The young need more career opportunities.
D．Agriculture needs different kinds of talents.
（3）What can we know about Beck's Hybrids？

A．It is under the control of a family.
B．It aims to offer service in harvesting.
C．It mainly provides computer technology.
D．It is the largest seed company in the nation.
（4）What does Bruce Kettler think is necessary？

A．Putting more money into agriculture.
B．Solving the problems facing agriculture.
C．Stopping the farming land from decreasing.
D．Applying modern technology to agriculture.

2．We all love chocolate，and most of us probably eat it every day，or at least several times a week.It is one of the most favourite kinds of food in the world，and many would say that they could not live without it.However，there are many facts about the world of chocolate that most people do not know.
Have you ever wondered where your chocolate comes from？Most of it comes from the labor of children.It is said that in Africa alone，there are about 70 million children working on chocolate farms.They lead a very hard life，and many live only on bananas and corn paste（糨糊）.One child who was interviewed said that he was tricked into believing he would be earning money to help his family.But the truth is that he is treated like an animal.The child has never even had the chance to taste the chocolate he spends his life producing.
The history of chocolate pretty much begins with the Mayans（瑪雅人）.Cacao（可可）beans were so valuable to Mayans that they were used as money.It is said that ten beans could buy a rabbit，and one hundred beans were enough to buy a slave（奴隸）.People would buy everything from food to tools with the beans.Generally，only the richer people drank chocolate regularly，because drinking your money is expensive.

（1）What do the African children who work on chocolate farms eat every day？

A．Bananas and chocolate.
B．Bananas and corn paste.
C．Cacao beans and corn paste.
D．Chocolate and cacao beans.
（2）Which of the following statements is TRUE according to the second paragraph？

A．Chocolate.
B．Animals.
C．Cacao beans.
D．Coins.
（4）What is this text mainly about？

A．Chocolate plays an important role in people's lives.
B．African children are producing chocolate in bad conditions.
C．Why only the rich can drink chocolate regularly.
D．Two unknown facts about chocolate.

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."

（1）What does the underlined phrase "look over their shoulders" in Paragraph 1 mean？

A．Watch out.
B．Take off.
C．Stand up.
D．Hide away.
（2）The author mentions 5 G phone networks in Paragraph 2 to show

.
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.
