I saw it first, Amy said, as she ripped the old leather wallet out of Charlies hands.

Without saying a word, as if they both understood that this was a secret they didn’t want to

share with anyone, they slipped into the alley, where no one could see them look inside

hundred- dollar bills. Amy, the more realistic of the two, did a quick estimate, thumbing

through the wad of cash.

They'd found the wallet in a flowerbed by the sidewalk, when Charlie dropped his cell

phone while he was trying to talk and eat a slice of pepperoni pizza at the same time. Amy

stuffed the wallet into her backpack and pulled Charlie along by his elbow toward her house.

As they rushed toward Viceroy Avenue, they talked excitedly about what they could do with

the money-buy gifts for parents and friends, get new clothes, travel to the rainforest in Costa

Rica, and adopt a whale. It looked like all of their dreams would come true. For the last block,

however, they didn’t talk. Each began to suspect that the other one was silently adding to the

list of things they could buy.

They finally reached Amy s house, but instead of going inside, they walked around the

house to the back porch. They opened the wallet and counted the money into piles of ten. The

total wasS2400- more money than either of them had ever seen. Then they both started talking

at once.

fifteen minutes to resigning themselves to what they must do next. For in the wallet's clear

plastic compartment, there was a driver's license. They knew what they had to do. Although

they would lose their newly-found treasure, in a way, they felt relieved.

D. nervous to disappointed

27. What did the children decide to do at the end of the story?

An article published in the prestigious scientific journal

Nature

sheds new light on an

important, but up-to-now little appreciated, aspect of human evolution. In this article

Professors Dennis Bramble and Daniel Lieberman suggest that being able to run was the

necessary condition for the development of our species which enabled us to come down from

the trees. This challenges traditional scientific thinking, which claims that the distinctive,

upright body form of modern humans has come about as a result of the ability to walk, and

that running is simply a by-product of walking. Furthermore, humans have usually been

regarded as poor runners compared to such animals as dogs, horses or deer. However, this is

only true if we consider running at high speed, especially over short distances. But when it

comes to long- distance running, humans do astonishingly well. They can keep a steady pace

for many kilometres, and their overall speed is at least the same as that of horses or dogs

Bramble and Lieberman examined 26 physical features found in humans. One of the

most interesting of these is the nuchal ligament(

项韧带

). When we run, this ligament prevents

our head from moving back and forth or from side to side. Therefore, we are able to run with

< br>小学英语、英语课件、英语教案、小学英语试题、英语导学案、英语单词短语

steady heads, held high. The nuchal ligament is not found in any other surviving primates,

such as apes and monkeys. Then there are our Achilles tendons (

跟腱

) at the backs of our legs,

which connect our calf muscles to our heel bones

—

and which have nothing to do with

walking. When we run, these tendons behave like springs, helping to push us forward.

Furthermore, we have low, wide shoulders virtually disconnected from our skulls(

颅骨

), a

physical development which allows us to run more efficiently.

But what evolutionary advantage is gained from being good long-distance runners?

Perhaps it permitted early humans to obtain food more effectively.

facts appear to be telling us is that running evolved in order for our direct ancestors to

compete with other meat- eating animals for access to the protein needed to grow the big

brains that we enjoy today,

humans chased animals for great distances in order to exhaust them before killing them.

says Lieberman.

reevaluate and further investigate how humans learned to run and walk and why we are built

the way we are.

28. In paragraph 1, what do the two professors suggest about humans' ability to run?

A. It is an evolutionary by-product of walking.

B. It helps to form people's ability to climb trees.

C. It has played an important role in human evolution.

D. It has not been adequately studied by scientists before.

29. What is true about the physical characteristics examined by the professors?

A. Achilles tendons assist people to walk long distances.

B. The human skull helps people to run more efficiently.

C. people's shoulders allow them to look from side to side.

D. The nuchal ligament enables people to hold their head steady.

30. According to paragraph 3, scientists believe that early humans_________.

A. always came across dangerous situations in life

B. ran after animals for long distances when hunting

C often failed to find food because they couldn't run fast

D developed their hunting skills by running long distances

31. Professor Lieberman thinks the new theory will _________.

A completely explain how running developed

B revolutionize the theory of human evolution

C. encourage more in- depth studies on the topic
