Believe it or not, America’ s favorite snack food is the potato chip. There is a story behind how it was
first made. One might think that somewhere a genius thought up the first potato chips, but it didn
that way. Picture an elegant restaurant in Saratoga Springs, New York, in 1853. The Moon Lake
Restaurant menus’ included French-fried potatoes, a popular food recipe brought back from France by
Thomas Jefferson. These were thickly cut potatoes, fried until golden brown and crisp on the outside. One
evening a guest in the dining hall felt that his potatoes were too thick and sent them back to the kitchen. The
cook sliced some potatoes thinner than before and prepared them for the complaining guest. He was still not
satisfied and sent them back again! By this time the cook was very angry and decided to do exactly what the
dinner guest wanted: slice the potatoes as thin as possible. Then they would be so crisp that the diner
wouldn ’ t be able to use his fork to eat them. When the paper-thin browned potatoes arrived, the diner was
pleased. He was so happy with them that other guests started ordering the new potatoes. The cook
plan to stop the dinner guest from complaining didn’ t turn out as expected. Soon Saratoga Chips appeared on the menu and became so popular that people wanted to take some home. The restaurant started selling
small packages of the potato chips. A few years later, they were sold all over the United Sates. But because
the potatoes had to be peeled by hand, it was a time-consuming job and potato chips were often out of stock.
In the 1920s, a mechanical potato peeler was invented and soon there were potato chips in abundance. They
gradually spread all over the world and have remained popular ever since.

What happens when a big meat eater is removed from its home? What happens when it comes back? The answers became clear in Yellowstone National Park, the oldest national park in the United States.
The story began more than 100 years ago, when most people wanted to kill off all wolves, for many
reasons. Ranchers (农场经营者 ) were angry that wolves killed some of their sheep and cattle. Park visitors loved to see deer, and wolves hunted them, too. At the time, people thought that wolves would eat humans. So people began to exterminate wolves throughout North America. In 1926, the last wolf in Yellowstone was killed.
Once the wolves were gone, mysterious changes began to happen in the park. Trees began to die.
Fewer birds nested in the park. Beavers (河狸 ) left to find new places to live. More and more wildlife disappeared.
Wildlife biologists realized that wolves had been important to the park. One winter morning in 1995, the first of several wolves was set free in the park, but a lot had changed in Yellowstone. Could the wolves survive there?
Naturalist Jim Garry remembers leading a class of wolf watchers when they heard their first wolf.
never saw the wolf, only heard a howl(嚎叫). Our hair stood on end. Our frozen smiles widened. Silently we put our thumbs up in a universal sign of success!”
Now songbirds have returned to the park. In the trees, the birds can hide, find insects to eat, and build nests. Tall trees act like big beach umbrellas over streams. As the trees came back, so did the beavers.
Not everyone agrees that wolves should travel free. After all, some wolves still take ranchers
and cattle. But today we know the wolf plays an important role. The wolf is a keystone animal --- an animal
that many others depend on for their survival.
78. The underlined word“ exterminate” in Paragraph 2 probably means ________.
A. eat
B. drive
C. kill
D. raise
79.From Jim Garry’ s words, we can learn that ________.
A.Wolves survived very well in the park
B.Wolves brought about changes in the park
C.They were glad that no wolves were in sight
D.They were afraid of being attacked by wolves
80.We know from the last two paragraphs that ________.
A.The park now takes on a new look
B.More wolves should be put into the park
C.Ranchers don ’ t realize the importance of wolves
D.Wolves should be stopped from harming sheep and cattle
81.What would be the best title for the passage?
A.Wolves are not bad guys
B.Bringing back the wolves
C.Keeping the balance of nature
D.Animals in Yellowstone National Park

Why can some people sleep through noises like a honking car or flushing toilet, while others are
人教版高中英语必修三上学期期中考试高二英语试题
awakened by the lightest sound?
To find the answer, sleep researchers at Massachusetts General Hospital conducted an unusual study of
12 self-described deep sleepers. After tests confirmed that the healthy volunteers were solid sleepers, they
took part in a three- night study in the university’ s sleep laboratory. The participants spent the night in a big
and comfortable room. But the room also included four speakers positioned near the top of the bed.
During the night, the deep sleepers were subjected to 14 different recorded sounds, like street traffic,
toilets flushing, an ice machine dispensing and an airplane flying overhead. Next door, the researchers
monitored their sleep patterns and brain waves.
As expected, all of the participants slept relatively well, but there were differences in how they
responded to the noisy interruptions. Some of the sleepers didn’ t wake up even when a sound was bla 70 decibels ( 分贝 ); others were awakened by sounds at 40 or 50 decibels.
The researchers discovered that the difference in a sleeper’ s reaction to noise could be predicted level of brain activity called“ sleep spindles’’ . A sleep spindlehigh-frequencyisaburstbrainof activity
coming from deep inside the brain during sleep. The source of the spindles is the thalamus, a part of the
brain that sends sensory information to the rest of the cortex ( 皮层 ).
Before the study, the Massachusetts researchers theorized ( 推理 ) that the spindles are the brain’ s way of preventing sensory information from passing through the thalamus and waking the rest of the brain
during sleep. They found that the sleepers who experienced the most sleep spindles during the night were
also the soundest sleepers and were least likely to be awakened by noise.
Scientists already know that most people become lighter sleepers with age, most likely because older
people experience less“ slow wave sleep’’ , which is the deepest stagePeopleofalsosleeproduce. fewer
sleep spindles as they age. But even when controlling for the stage of sleep a person was in, the number
of sleep spindles still predicted their risk for awakening because of noise.
More research is needed, but the findings suggest that a better understanding of sleep spindles could
lead to new behavioral or drug therapies for people with sleep disorders. For instance, future studies may
try to determine whether diet, exercise or other behaviors may influence the number of sleep spindles a
person produces during the night.
82. Some participants can sleep well through loud noises mainly because ________.
A. their brains don’ t respond to outside noises
B. their brains react differently to noises
C. they adapt to the environment quickly
D. they don’ t pay attention to the monitors
83. Scientists believe that the key to affecting deep sleep is ______.
A. sensory information
B. stages of sleep
C. sleep disorders
D. sleep spindles
