One night,I received a message from my former classmate,someone I hadn't spoken to in 15 years."Hey
Mary,"she said."I know you've atways been an animal lover.I have a mini pig that is not getting along with my
dogs.So I can't keep the pig."Of course,the whole situation was strange,but I've always been a trusting person.I
replied "Let me do some research and I'll get back to you."
I knew nothing about mini pigs.I didn't know what they ate;and I had no idea how big they got.Once I
started doing some Intemet research,I found a few people claiming that"there's no such thing as a mini-pig,"but I
was blinded by my sudden fascination and my faith in my onetime friend.She had said the pig was six months old
and this mini pig would grow to be about 70 pounds,maximum.That was pretty close to the size of Shelby,one of
my dogs.So I told my former classmate that I'd take the animal.
It's intractaole enough bringing a pig back to the house I share with two-dogs,two cats and my husband,
Derex.But I knew I.wanted the pig and the day finally came..When Derek went back,he stood in the door way like
a statue.Every emotion other than happiness flashed across nis.face He was extremely angry The only positive
thing I could say was,"She's a mini pig!She'll stay small!Surprisingly,soon enough,the lovely pig smoothed
things over by itself.Derek started talking about where the pig's litter (would go.You don't care about"litter"
of someone you're getting rid of.
However,a few months later,she'd started closing in on 80 pounds.It was becoming clear that I'd probably
adopted a commercial pig and she was going to be enormous,While it might be unexpected,it's more than worth it
for the happiness she has added to our world.
241 What tid tne author do immediately after receiving her former classmate's message?
A.She decided to take the pig without hesitation.
B.She discussed the matter with her husband Derek.
C.She looked up information about mini pigs onllne.
D.She asked the classmate about the pig's habits.
25.The word "intractabie"in the third paragraph most probably means
A.easy and comfortable
B.difficult to handle
C.exciting and interesting
D.common and predictable
26.How did Derek feel when he first saw the pig?
A.Curious and interested.
B:Shocked and angry.
C.Sympathetic and warm.
D.Relaxed and joyful.
27.What is the mamn theme of the passage?
A.The importance of rusting old friends.
B.The need for researching before keeping a pet.
C.The challenges and joys of adopting an unexpected pet.
D.The differences between mini pigs and commercial pigs
4
C
As Internet users become more dependent on the Intemet to store information,do people remember tess?If
you know your computer will save information,why store it in your own personal memory,your brain?Experts are
wondering if the Internet is changing what we remember and how.
In.a.recent study,Professor Betsy Sparrow eonducted same experiments.She and her research team wanted to
know the Interet is changing memery.In the first experiment,they gave people 40 unimportant facts to type into a
computer.The first group of people understeod that the computer would save the information.The second group
understood that the computer would not save it.Later,the second group remembered the information better.People
in the first group knew they could find the information again,so they did not try to remember it.
In another experiment,the researchers gave people facts to remembet,and told them where to find the
information on the Intemet.The information was in a specific computer folder.Surprisingly,people later remember
the folder location better than the facts.When people use the Intemet,they do not remember the information.
Rather,,they remember how to find it..This is called“'transactive memory(交互记忆)”
According to Sparrow,we are not becoming people with poor memories as a result of the Interet.Instead,
computer users are developing stronger transactive memories;that is,people are leaming how to organize huge
quantities of information so that they are able to access it at a later date.This doesn't mean we are becoming either
more or less intelligent,but there is no doubt that the way we use memory is changing:
28.The passage begins witn two questions to
A.introduce the main topic
B.show the author's attitude
C.describe how to use the Internet
D.explain how to store information
29.What can we learn about the first experiment
A.Sparrow's team typed the information into a computer.
B.The two groups remembered the information equally well.
C.The first group did not try to remember the information.
D.The second group did not understand the informatien.
30.In transactive memory,people
A.keep the information in.mind
B.change the quantity of information
C.organize information like a computer
D.remember how to find the information
31.What is the effect of the Internet according to Sparrow's research?
A.We are using memory differently.
B.We are becoming more intelligent
C.We have poorer memories than before.
D.We need a better way to access information
You stayed up too late looking through your phone,answering emails or watching just one:more video.The.
next morning,you feel sleepy and impatient.That dessert or sandwich suddenly looks more appealing than your
usual yogurt and berries.This isn't just about willpower.Your brain,short on rest,is pushing you toward quick,
high-calorie roods.
Research shows that lack of sleep disturbs hunger signals,weakens self-control and increases your risk of
weight gain.Sleep loss affects millions.More than one-third of U.S.adults regularly get less than seven hours of
sleep per night.Nearly three-quarters of teenagers fall short of the recommended 8-10 hours sleep during the school
week.Firstreependents,ncluding nurses,firefighters and emergency workers,are especially affected due.tomight
shifts and uncontrollable schedules.These patterns disturb the body's intemal clock and are linked to increased
appetite(胃口),poor eating habits and higher risks for obesity and metabolic(代谢性的)disease.
Stdies show that after just one night of sleep loss,reward-related areas such as the amygdala a part
o braie that drives motivation-and reward-seeking become more,reactive to finding food.Your brain becomes
more excited by junk food and less.capable of resisting it.Participants m steep loss studies not only fated
ngb-calorie foods as more desirable but were also more likely to choose them,regardless of how hungry they
actually felt.
Sleep is as important as diet and exercise.in maintaining a healthy weight Fortunately,even a few nights of
consistent,high-quality sleep can help rebalance key systems and start to improve some of these effects.So the
next time you find yourself reaching for junk food after a short night,recognize that your body is reacting to stress.
Sleep is your most powerful tool for appetite control,energy control and long term health.
32.What problem does the author point out-in paragraph 1?
A.Sleep ioss stimulates the brain for appetite.
B.Staying ap late can rage people dizzy.
C.High-calorie foods are more attractive.
D.People are addicted to using mobile phones.
33.Why are first respondents more likely to suffer from sleep loss?
A.They bear expectation of the soclety.
B.They have unhealthy lifestyles.
C.They have uncontrollable and shifting schedules.D.They have much pressure-from the workload.
34.Why is the brain more likely to change into the reward mode after a lack of sleep
A.The brain reacts more quickly to tfe envmronment.
B.Sleep loss changes how the brain rates food.
C.The brain becomes more active and unrealistic.
D.Sleep loss changes how the body absorbs nattients.
.35.Which would be the best title for the text?
A.How Sleep Loss Disturbs Body's Internal Clock
B.WhyQuaftty Sleep Matters for Weight Management
C.Sleep,Diet and Exercise:Keys to Healthy Living
D.Sleep Shortage:The Hidden Driver of Junk Food Desires

Two fast friends were Willie Brown and his little dog Bounce Willie could never think of taking a walk
without Bounce Cake and play were equally shared between them.
Willie taught his dog many running tricks and often said that Bounce could do almost anything in the world but
talk.
There came a time,however,when Bounce really told Willie's father something,though he could not talk.Let
me tell you how he did this.
It was on a bright summer afternoon.Willie had strolled with Bounce down to the river wnich was not more
than two blocks from his father's store.Willie began to throw stones into the water and to watch the ripples as they
made one circle after anether.Bounce lay on the grass,watching the flies that buzzed around his nose and catching
any that came too near.
There were some logs原木,圆材)floating in the river near the store.Willie jumped upon one of them to see if
he could throw a stone across the river.
He drew back,and sent the stone with all his might.Just as it left his hand,the log turned and he fell into the
water.He was very much frightened,for he did not know how to swim,and there was no one to hear,though he
called as loud as he could for help.
Poor little Bounce barked in distress.If he had been a big water dog,he could have jumped in and brought his
master out.
He ran up and down the bank two or three times,barking,looking first at Willie and then around.

He ran up and down the bank two or three times,barking,looking first at Willie
and then around.He ran as fast as he could to Mr.Brown's store.The door was
closed,so he scratched it and barked loudly till someone opened it.He locked his jaw
on Mr.Brown's clothes,pulled him to the door,then ran back-barking and jumping.
Feeling something wrong,Mr.Brown grabbed his hat and followed.Suddenly,Mr.
Brown thought of Willie,picking up his pace.At the river,he saw Willie's hat
floating,with his small arm sticking up.Mr.Brown jumped in,caught Willie just
before he sank,and carried him to the bank.Willie calmed down,and Bounce wagged
his tail happily.Though the dog couldn't speak,his actions told a warm truth:loyalty
speaks louder than words.

M:All right,class.Before we get started,I want to make an announcement.The quiz I had
planned for today will have to wait until next Tuesday.I didn't have time to get it ready,so you
have a few extra days to study.
Now,let's get to today's topic.Some of you may not like science,but you should at least
respect it because it adds so much fo our lives.Recently,I read about a newly created plastic
that changes color when it's stretched.How did the scientists dream up this idea?They could
never have done it without observing nature.While studying certain insects,the scientists found
that the insects'shells changed color when looked at from different angles.They immediately
thought of ways to use that science to benefit humans,The scientists plan to use this plastic on
food packages to tell us when our food goes bad and on our money to make it more difficult for
criminals to copy.So when you're walking to class each day,try to take some time to observe
nature around you.You never know when you'll have a bright idea that can change how we
five.
