12.Think Positive and Feel Positive
When you're in a stressful situation,are you confident or unsafe?Do you react positively or negatively?
(71)A  A study by researchers at the University of Notre Dame found that negative thinking,and depression coming from it,can be catching in certain circumstances.
For example,the researchers studied 103 freshman college roommates who'd been paired casually.(72)E     Specifically,the researchers measured the subject's likelihood to see negative events as a reflection of their abilities and disadvantages.
After only six months,it became clear that thinking patterns and styles can be catching.(73)D
And students paired with more positive thinking roommates were more likely to become more positive in their thinking and report less depression.
(74)B   So they might be particularly accessible to adopting the thought and behavior patterns of people around them-perhaps more so than people in less intense situations at other stages of life.
But maybe not.Other research has shown that,in general,people are affected by how those around them think.(75)F  

A.The answer may depend in part on whom you're around.
B.Now college freshman are in a unique,life changing environment.
C.However,think positive and feel positive is quite important for college students.
D.Students paired with a negative-thinking roommate"caught"that style and became more depressed themselves.
E.They measured each roommate's cognitive weakness,or tendency to give in to negative thinking and depression.
F.So surrounding a negative,depressed person with people who think positively could be a powerful form of treatment.
G.But what was to the researchers'embarrassment was that the subjects never talked with each and stayed apart from each other for most of the time.
11.Rene Laennec was a French doctor who learned to tap on people's chests to find out illness from an Austrian doctor named Leopold Auenbrugger.As a boy,Leopold used to tap wine(41)containers(contain) in his father's inn to see how much wine they held.A full one made(42)a  different sound from an empty one.When he became a doctor,he(43)tapped (tap)people's chests to see how much liquid was in their lungs.Laennec did the same and learned to tell by tapping carefully on a chest(44)whetherit was diseased or not.But he was even more interested(45)in diseases of the heart,and he wished that he could hear heartbeats clearly.In those days,a doctor would place his head on a patient's chest to listen,but if the patient was(46)extremely(extreme) fat it was impossible to hear any heartbeat at all.
One day when Laennec(47)was walking(walk) in the park,he saw some girls playing with a see-saw(跷跷板).One of them scratched the end of the board while the others placed their ears against the other end.On walking up,the doctor was asked why the sounds travelled along the wood."The sounds are magnified(放大),girls,er…"Suddenly he turned and rushed back to the hospital.Quickly(48)taking(take) some thick paper,he rolled it up like a tube and began listening to patients'chests.He heard the heartbeats and(49)their(they) breathing clearly.Laennec soon made a better instrument of wood,one he called a stethoscope(听诊器).Later,they(50)were made (make) of steel and rubber.
8.Things to Know Before Adopting a Dog
The idea of giving someone a puppy for Christmas provides a warm fuzzy response for most people.(36)C  Pets carry a lot of responsibility,but they reward their owners with years of love and devotion.
Be Realistic About How Much Time You Have
In a busy world,full of work,soccer games,and family dinners,time is more precious.When adopting an animal it is important to consider how much time you have.to devote to training and caring for it.(37)D  If you have plenty of extra time to devote to a pet,a puppy is a good choice.
Think About How Much Space You Have
Large dogs naturally require more room than small dogs.They need big yards to run in,or a nearby area where they can go for longer walks.If you live in a small apartment on an upper floor,this can be a problem.(38)E  Smaller dogs take up less space and are often easier to transport up and down stairs and in elevators.If you have a large home with a big backyard where your dog can run and play,then a larger breed may be a good fit for you.
 (39)B    
If you have small children,a patient dog with a high tolerance level is necessary.Kids explore with their hands,and they are likely to touch,tug,pet,and crawl all over the new dog.In this situation,you need to choose a dog with an easygoing temperament-who will not become frustrated and bite.(40)G

A.Consider the Other Pets in Your Home
B.Choose the Right Dog for Your Situation
C.However,adopting a dog is not something to be taken lightly.
D.A puppy requires a lot more time and attention than an older dog.
E.Walking around a small space with a Labrador underfoot can be frustrating.
F.Adopting a dog rather than buying one benefits both the animal and your family.
G.Breeds like Golden Retrievers,Labradors,and Border Collies are well known for their family friendly attitude.
7.Are you still worried about overcharging for your luggage over the weight limit?An"Airport Jacket"containing up to 15kg luggage is designed to help frequent flyers bypass(绕过)airport baggage queues,reduce baggage fees and really lower the risk of lost luggage.
"With airlines beginning to charge for carry-on baggage as well as severely limiting 10aggage allowances for the low fare economy traveler,my partner and I have designed a jacket that can wear your laptop,tablet,two pairs of shoes,a pair of jeans,five T-shirts,a jumper and a camera,"designer Claire Murphy explains."It totals 14 deep pockets,including 8 pockets at hip length,11 pockets at three-quarter length and 14 pockets at full length."
Claire and Benke Murphy came up with the idea while traveling home with their newborn child.They had so much extra carry-on luggage that the airline tried to charge them $ 140 for it,more than the cost of their tickets.So they had to put clothes,chargers,diapers and toys into their pockets,until just over the weight limit.They escaped the tax,but everything sticking out of their pocket saw a pretty uncomfortable plane ride.
However,people have been raising questions about the usefulness of the Airport Jacket,especially the trouble of going through security checkpoints.They are arguing that having to take all out and then putting them back into the pockets is not worth the few tens of dollars you save on a checked luggage.
But Benke claims that walking through airport security is not an issue as long as you follow guidelines for carry-on luggage."It only needs to be worn when checking in and at the boarding gate.What's more,Airport security is not looking at how you store your luggage but checking its contents."
Its makers are currently running a crowdfunding campaign on Kickstarter,trying to raise  AU100,000.Butthey'veonlyraised AU3,675 so far,although they still have 37 days to go,so it's still hopeful And even if this fails,they may still find a way to get it to market.
