Years ago, when I started looking for my first job, wise advisers advised, “Barbara, be enthusiastic! Enthusiasm will take you further than any amount of experience.” How right they were!

       “Nothing great was ever achieved without enthusiasm.” wrote Ralph Waldo Emerson. It is the paste that helps you hang on there when the going gets tough. It is the inner voice that whispers, “I can do it!” When others shout, “No, you can’t!” It took years for the early work of Barbara Mclintock, a geneticist who won the Nobel Prize in medicine, to be generally accepted. Yet she didn’t stop working on her experiments. Work was such a deep pleasure for her that she never thought of stopping.

      We are all born with wide-eyed, enthusiastic wonder and it is this childlike wonder that gives enthusiastic people such youthful air, whatever their age. At 90, pianist Pablo Casals would start his day by playing Bach. As the music flowed through his fingers, joy would reappear in his eyes. As author and poet Samuel Ulman once wrote, “Years wrinkle(使皱) the skin, but to give up enthusiasm wrinkles the soul.”

     Enthusiastic people also love what they do, without being affected by money or title or power. Patricia Mellratl, retired director of the Missouri Repertory Theater in Kansas City, was once asked where she got her enthusiasm. She replied, “My father, long ago, told me, ‘I never made a penny until I stopped working for money.’”

      If we cannot do what we love as a full-time career, we can as a hobby. Elizabeth Layton was 68 before she began to draw. This activity ended periods of depression that troubled her for at least 30 years and the quality of her work led one critic to say, “I am tempted into a genius.”

   We can’t afford to waste tears on “might-have-been”. We need to turn the tears into sweat as we go after “what-can-be”．We need to live each moment whole-heartedly, with all our senses—finding pleasure in the sweet smell of a back-yard garden, the simple picture of a six-year-old, and the beauty of a rainbow.

If you are afraid of the dark，it’s not a big deal．It’s perfectly normal to feel afraid After all，animals do too. “Fear matters，”says Karen Warkentin，an ecologist．“It’s a good thing，” she adds, “because fear makes you do things that keep you alive.”
Like kids，many animals experience fear and they respond to the feeling in variety of ways．A
frightened turtle pulls its head and legs inside its shell．A small fish will swim away when a big，hungry fish approaches．
Some animals respond to fear in ways you might not expect．The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red—eyed tree frogs in Costa Rica.
In this species，female frogs attach jellylike clumps（果冻一样的块状物）of their eggs to the undersides of leaves．The leaves hang on branches that dangle（悬挂）over ponds．After they hatch from the eggs，the tadpoles（蝌蚪）then fall into the water，where they eventually grow into
adult frogs.
Tree frog eggs usually grow for 6 days before hatching．If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.
If hatching early helps protect red—eyed tree frogs from snakes，you might wonder why their eggs don’t always hatch sooner．It turns out that hatching early brings its own danger．Once tadpoles land in the water，hungry fish and other animals like to eat them too．Staying in their eggs for a full 6 days，then，allows frog embryos（胚胎）to grow big and strong．This extra growth improves their chances of surviving in the water．
68．It can be inferred from the passage that fears______
A．help animals grow bigger and stronger
B．are less common among young animals
C．help animals move a lot to fit the environment
D．are more or less important in order for animals to survive
69．We are told in the passage that tree frogs______
A．face danger both inside their eggs and in the water
B．will grow fast if they fall into the water later
C．are surprisingly clever when inside their eggs
D．stay in their eggs longer if they are frightened
70．What do you think would be discussed in the following paragraph?
A．Further explanations as to why tree frogs hatch ahead of schedule．
B．How the unborn frogs know when a snake is about to attack them．
C．Another example of animals that responds to fear in an unexpected way．
D．How tree frogs improve their chances of survival before falling into the water.

How Do Animals Catch Their ZZZ’s?

Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard（蜥蝎）likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it ,it will shake the branch and knock the lizard off ,and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping.

Corillas（大猩猩）like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches ,twigs ,and leaves into a comfortable bed .Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks ,they don’t use a nest .They just lock their feet around a branch and hang on .A special tendon（腱）in their legs in automatically tight when they are at rest ,so they won’t let go and fall.

Dolphins live underwater ,but must come to the surface to breather .Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this ,lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open.
