A.The engine in your body．
B.The location, size and heartbeat of a heart．
C.What happens when the heart beats?
D.How does your heart work?
E. How do we know about the heart?
F.What can a doctor tell by feeling your pulse?
1._______ Your heart is sometimes called the engine or the motor in your body and sometimes called the pump．It works away, both day and night．First it pumps out some blood, rests for a few seconds, and then it pumps some more．In a normal day, the heart pumps about 2,500 gallons of blood from the auricles and ventricles．
2.________ When your heart beats, it is pumping blood to all parts of your body．If you could examine your heart closely, you would see that it is really two pumps placed side by side, and working at the same time．Each pump has two parts, the upper part called the auricle(心房), and the lower part called the ventricle(心室)．The auricles receive the blood as it comes into them after it has been pumped through the body．The ventricles pump the blood out．The right one pumps the blood to the lungs and the left one pumps the blood to all other parts of the body．At the top and bottom openings of each ventricle are valves(阀门) which make the blood go in only one direction．
3.______ Your heart is located in your chest, a little to your left．This heart of yours, which is about the size of your two fists held together, beats about 90 times a minute．A grown person’s heart beats about 60 to 80times a minute．The heartbeat is not just the same in all persons, and it is not the same in any one person at all times．
4._______ By using a stethoscope to listen to the heart, the doctor can tell whether your heart is beating evenly and whether the valves are closing tightly．The stethoscope makes these sounds so clear that the doctor can hear them easily．The stethoscope has an earpiece that he places on your chest and tubes that he places in his ears．The earpiece carries the sound of your heart’s beating along the tubes to the doctor’s ears, and it makes the sound seem much louder than it really is．The doctor could listen to your heartbeat by pulling his ears against your chest．
5._______ An easy experiment can help you understand what happens when the heart beats．You can do this experiment with a hollow rubber ball．Make a small hole in it, and fill the ball with water through the hole．When you squeeze the ball, you will notice how the water comes out in a spurt each time you squeeze．After each spurt the ball comes back to its round shape again．Something like this happens when your heart beats．The muscles in your heart grow smaller, or contract, and squeeze the blood out of the heart．Each time this happens, we say your heart is beating．Perhaps you have noticed that the doctor places his finger on the pulse in your wrist when you are ill．By doing this he can tell how fast your heart is beating．
Here’s something that might make you feel a little better the next time you have a serious case of hanger - you’re not being irrational or unreasonable, it’s just science．
The concept of being ‘hangry’ - angry because you’re hungry - comes up among ScienceAlert staff．But there’s nothing wrong with being hangry - there’s a scientific reason why having low blood sugar can make some people aggressive．
According to a study published earlier this year, blood sugar levels directly related to how married couples were likely to treat each other．Working with 107 couples over three weeks, the researchers, led by psychologist Brad Bushman from the Ohio State University in the US, found that when individuals experienced lower than usual blood sugar levels, they became increasingly aggressive and mean towards their significant others．
This was measured through the use of a good old-fashioned voodoo doll — the volunteers were each given one, along with 51 pins, to represent their spouse-a partner in marriage．Each person’s aggressive impulses（冲动）were then measured based on how many pins they stuck into their spouse-dolls every night throughout the experiment．
Aggression, on the other hand, was measured by volunteers blasting（炮轰）their spouse with a loud and unpleasant noise in the headphones they had to wear．
Turns out that the volunteers who experienced the lowest blood sugar levels stuck more pins into their voodoo dolls, and forced louder and longer blasts of noise on their spouses than those who had plenty of glucose(葡萄糖) in their system．
"People are often the most aggressive against the people to whom they are closest — intimate partners,” the researchers concluded．"Intimate partner violence might be partly a result of poor self-control．Self-control of aggressive impulses requires energy, and much of this energy is provided by glucose from the food we eat．"
As Susannah Locke explains at Vox, glucose is the only molecule（分子） that our brains will accept as fuel．This means, quite simply, that when we’re not producing enough glucose, our brains won’t function properly．It also means that we lack the energy we need to maintain self-control, which is why we’re more likely to hit or criticize others suddenly in an uncharacteristic manner when we haven’t eaten in a while．
1.According the passage, what can make you feel better?
A．Knowing that your are being irrational．
B．Knowing that your are being angry
C．Knowing that you are being hungry
D．Knowing that you are angry for a reason．
2.How did the researchers get the final result of the experiments in various ways?
A．By making good use of a doll to represent their spouse．
B．By using voodoo dolls , pins and headphones to measure their aggression．
C．By measuring aggression based on how many pins they stuck into their dolls
D．By measuring aggressive impulses in terms of their blasting their spouse with a noise．
3.Which of the following is right according to Susannah Locke?
A．Glucose is our brain's fuel．
B．We lack energy to control ourselves．
C． Without glucose, our brain will function properly．
D．We are more likely to lose control if we produce enough glucose．
4.From the passage, in which condition will you be more likely to feel angry?
A．At 8:00 a．m, you are driving a car alone after having breakfast．
B．At 11．00 a．m, you are in your office with colleagues waiting for the lunch．
C．At 5:00 p．m, you are cleaning the house at home while your wife is cooking．
D．At 6:00 p．m, you are taking a walk with your family after having dinner．
5.What did researchers conclude from the research?
A．Lower blood sugar level had less pins stuck than higher blood sugar．
B．Poor self-control could cause aggression between intimate partners．
C．People are often the most aggressive against the strangers．
D．People with more glucose force louder blasts of noise

Miya volunteered abroad in Costa Rica with World Endeavors assisting at an orphanage(孤儿院)and teaching English at a school．
As a freshman at Yale University, Miya had plans to go to medical school．Knowing that her next two summers would be occupied doing research, Miya decided to go abroad the summer after her freshman year．“I wanted to improve my command of the Spanish language and learn about the culture and history of another country,” she explained．In the summer of 2014, Miya volunteered for six weeks in the World Endeavors program in Atenas, Costa Rica, working in an orphanage and teaching English to children in grades one through six．
“A long time before I left, I had positive expectations for the trip,” said Miya．But as the date grew closer she found herself getting more and more nervous．“I thought, what if my host family doesn’t like me? What if I get sick?”
Her fears, as fears often are, turned out to be unfounded．“The people were so supportive and loving,” said Miya．“I felt like I was part of the family．”
Miya’s host family had a large network of cousins who all lived within shouting distance． The family would cook together, and at night would go dancing, talk or eat ice cream．She noted that the World Endeavors staff on location—Diego and Mercedes, and Mercedes’ husband and daughter –were particularly helpful, taking her right to her neighborhood from the airport, and checking up periodically to make sure everything was going well．
While her nights were spent dancing, cooking, and talking with her host family, Miya’s days were occupied with the children of her host city．“I would teach in the morning, and work in the orphanage in the afternoon,” said Miya, whose placements were within walking distance from her host family．While the children were a lot of work, Miya felt a strong connection to the kids in the orphanage．
Miya noted that Costa Rica is one of the more developed countries in Central America． A nearby Internet café, for example, helped her to stay in touch with her family while she was away．And now, back in the United States, the Internet helps her keep in touch with her host family．Their correspondence continues in Spanish．And her host parents, Rosario and Jorge, recently sent Miya a Christmas card through the mail．
Back at school, Miya continues to pursue her instinct to improve education through volunteering． She participates in a mentoring group and works on a community health education program for high school students．Her time in Costa Rica, she says, “fits right into my interests in global health．”
