Humans might be the most highly-evolved species on the planet,but most animals possess skills we can
only dream of having.Imagine how much electricity we could save if we could see in the dark the way cats
do. Imagine leaping from tree to tree like a monkey.Giraffes(长颈鹿),which are otherwise calm and good-
natured,sleep only 4.6 hours a day.
We realized a long,long time ago that nature provides the best blueprint(蓝图)for invention.We've
borrowed canals from beavers(河狸)and reflectors from cat's eyes.Although the words "bionics" became
popular only after the 1960s,history shows that nature has always provided ideas on solving everyday prob-
lems. Our archives(档案)don't go back to the time of Leonardo da Vinci and his bird-like flying machines,
but we can take you to the late 19th century,where we applied those same principles for building our first
practical airplanes.
To prepare for their flight at Kitty Hawk,the Wright brothers studied the movements of pigeons to figure
out how they stayed high up when they were heavier than air. Their success inspired scores of successors to
improve on the airplane by studying various aspects of nature,One of Orville Wright’、pupils caught and
stuffed seagulls to examine their wingspan.Meanwhile,two French inventors examined spinning sycamore(美
国梧桐)seeds in an effort to apply those same motions,reversed,to a helicopter.
Some examples are more obvious than others.The outside of the airplane designed by the Wright

But imagine how life would change if we could achieve that.

What happened after the Wright brothers' success?
A:People carried out a systematic study on pigeons.
B:People could fly their airplanes for fun.
C:People kept their airplanes at a French gallery.
D:People studied more animals and plants to develop the airplane.

Our dream is the song of our soul. Life without one is reduced to a hollow existence. But life with a dream is filled with meaning and purpose.Most of us have a dream, or heart's desire. But the trouble is most of us have the on/off switch of our dream set to OFF. Whenever we say, I can’t, we set the switch to OFF. Whenever we believe we can, we set the switch to ON. Simple, isn't it? Just because I believe I can do something doesn't mean there won’t be any problems. But once I believe I can do it, I will seek solutions for every problem I stumble on. And since it is a law of life that we find what we look for, if I look for solutions, I will find them.Any worthy dream is a dream worthy of accomplishing. Once I realize I can do it, the next step is to make a commitment. As soon as we make a commitment, great power is released. What seemingly were insurmountable hurdles are now reduced to obstacles of laughable insignificance. But we won’t reach this stage until we decide to stop talking and start acting. Unless we commit ourselves, self-doubt will ferment and block our way.Our dreams don’t have to be grand to be great. An aunt of mine sold gloves in a department store for most of her life. Her dream was to be the friendliest and most helpful salesperson around. Year after year, the same customers would return and deliberately seek her out. She brightened everyone's day and touched the lives of thousands. Was her dream any less significant than that of aprominent person? Of course not. We all have the power to follow a dream that will make a difference to us and those we meet.No dream is too small; no dream is too big, so hold on to your dream. Langston Hughes tells why, Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly.So,what are you waiting for? Follow your dream!(1)According to the author, dreams ___________.A、refer to dreams in our sleepB、refer to dreams in the daytimeC、gives meaning and purpose to our lifeD、enables life to be a hollow existence(2)What are the stages in following a dream?A、Setting the switch of our dream on, making a commitment, and releasing the power.B、Setting the switch of our dream on, committing ourselves, and following the dream.C、Believing we can do it, committing ourselves, and acting.D、Believing we can do it, acting and making a commitment.(3)What does the dream of the author's aunt illustrate?A、To illustrate we should commit ourselves and start acting.B、To illustrate our dreams don’t have to be grand to be great.C、To illustrate her dream was to be the friendliest and most helpful salesperson.D、To illustrate we all have the power to follow a dream.(4)Which of the following statements is NOT true?A、Whether the switch of your dream is ON or OFF is left entirely to yourself.B、If we believe we can do it, there won’t be any problems.C、We will find what we look for.D、The author's aunt's dream was not any less significant than that of a prominent person.(5)The passage mainly tells us that __________.A、a dream gives meaning and purpose to our life.B、if dreams die, life will become meaningless.C、we should follow our dream which will make a difference to us and other people.D、a worthy dream is a dream worthy of accomplishing.

问答题Practice 1  No one knows what time itself is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way we mark its passing. For all our success in measuring the tiniest parts of time, time remains one of the great mysteries of the universe.  One way of thinking about time is to imagine a world without time. There could be no movement, because time and movement cannot be separated. A world without time could exist only as long as there were no changes. For time and change are linked. When something changes, you know time has passed.
