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 a 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.
1.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
2.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
3.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.

高三英语单项填空中等难度题查看答案及解析
She’s not afraid of anything. Snakes? No problem. Walking alone in the dark? Easy. We’re not talking about a superhero here -- SM is a 44-year-old mother. And she’s fearless because she happens to be missing part of her brain: the amygdala(扁桃腺).
Shaped like a pair of almonds sitting in the middle of your brain, the amygdala helps control fear and anxiety. A rare condition called Urbach-Wiethe disease left SM without her amygdala, and seems to have completely erased her sense of fear.
To try to understand how the amygdala works, a team of researchers made their efforts to scare SM. They showed her horror movies and took her to the Waverly Hills Sanatorium Haunted House in Kentucky. She pushed out one of the monsters(巨物) and laughed. SM said she didn’t like snakes, but at a pet store full of poisonous creatures, she kept asking to touch them. When asked to rate her feelings, SM reported feeling surprised or disgusted, but never fearful.
“She tends to approach everything she should be avoiding,” says Justin Feinstein of the University of Iowa. This means the amygdala could control deeper urges to approach or avoid danger. Other scientists have a different opinion, though. “I don’t believe you can make a general statement about what the amygdala does by a single case study,” Elizabeth Phelps said. In 2002, Phelps published a study on a similar patient with amygdala damage who still showed fear.
It may sound like fun to be totally fearless, but we get scared for a good reason. “The nature of fear is survival and the amygdala helps us stay alive by avoiding situations, people, or objects that put our life in danger,” Feinstein said. SM was once followed in a park after dark by a man with a knife, and she simply walked away. “It is quite remarkable that she is still alive,” said Feinstein.
1.SM dares to walk alone in the dark mainly because ____________.
A. she is a superhero
B. she has experienced such conditions a lot
C. she is a mental patient
D. she has no sense of fear
2.Researchers tried their best to frighten SM in order to find ___________.
A. The function of a particular organ
B. SM’s reaction of fear and anxiety
C. The process of removing amygdale
D. A special way to get along with monsters
3.What do we know from the research on SM?
A. It was easy for her to avoid danger.
B. SM never felt fearful but disgusted.
C. SM was frightened by nothing except monsters.
D. SM got along well with the snakes.
4.What is Elizabeth Phelps’ attitude toward the function of the amygdala based on the research on SM?
A. Indifferent B. Supportive C. Disapproving D. Interested
5.What can we infer from the last paragraph?
A. People can remove their amygdala to be fearless.
B. SM will be admired because of her bravery.
C. No one can survive if their amygdala is removed.
D. The sense of fear is crucial to humans.

“Don't worry if you have problems!” It is easy to say until you are in the midst of a really big one.The only people who don't have troubles are gathered in little neighborhoods.Most communities have at least one.We call them cemeteries.If you're breathing, you have difficulties.It's the way of life.And believe it or not, most of your problems may actually be good for you! Let me explain.
Maybe you have heard the Great Barrier Reef, stretching some 1,800 miles from New Guinea to Australia.Tour guides regularly take visitors to view the reef.
On one tour, a traveler asked the guide an interesting question."I notice that the lagoon (泻湖) side of the reef looks pale and lifeless, while the ocean side is vibrant and colorful," the traveler observed.Why is this?
The guide gave an interesting answer, "The coral around the lagoon side is in still water, with no challenge for its survival.It dies early.The coral on the ocean side is constantly being tested by wind, waves and storms.It has to fight for its survival every day.As it is challenged and tested, it changes and adapts.It grows healthy.It grows strong.And it reproduces."
Then he added, “That's the way it is with every living organism.”
That's how it is with people.Challenged and tested, we come alive! Like coral pounded by the sea, we grow.Physical demands can cause us to grow stronger.Mental and emotional stress can produce tough-mindedness and resiliency.Spiritual testing can produce strength of character and faithfulness.So, you have problems? No problem! Just tell yourself, "There I grow again!"
Remember: A smooth sea never made a skilled mariner.
1.Who has no problems according to the passage?
A.The persons who are very famous.
B.The persons who have much money.
C.The persons who have been born.
D.The persons who are living in the cemeteries.
2.In the writer's opinion, ________.
A.problems bring us much trouble
B.problems have two sides, good or bad
C.we should try to stay away from any trouble
D.the fewer things we do, the less trouble we'll meet
3.The reason why lagoon side of the reef has no life is _______.
A.it hasn't got any sunlight
B.it has less energy than others
C.it never faces any challenge and tests
D.it has no work to do every day
4.After reading this passage, we should ________.
A.regard any problem as challenge
B.learn from the lagoon side
C.worry your problem
D.enter into cemeteries
