Snake dishes have become popular  recent years. Snake meat in various flavors(風(fēng)味) is often seen in restaurant advertisements. Eating snake seems to be now in vogue(盛行), and      you haven’t eaten snake yet, you are considered “ out of date”. But I wonder whether all the trends are worth       (follow).

   Some people may defend themselves     saying that snake meat is nutritious. But these people don’t realize that many parasites (寄生蟲),     (find) inside snakes, will do harm to our health.

   According to a survey, about 1,000 tons of snakes are eaten every year in China and sometimes as many as 10 tons of snakes     (serve) on dinner tables in Shenzhen in a single day!

   These figures warn us that if no      (act) is taken, the number of snakes will drop and that will make      increase in mice and worms population,      will result in a decrease (減產(chǎn)) of crops output. Who will see such tragedy happen?

   So let’s start not to eat snakes any more because “ to protect the snake is to protect  .”

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(果凍一樣的塊狀物)of their eggs to the undersides of leaves.The leaves hang on branches that dangle(懸掛)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.a(chǎn)re less common among young animals
C.help animals move a lot to fit the environment
D.a(chǎn)re more or less important in order for animals to survive

A.face danger both inside their eggs and in the water
B.will grow fast if they fall into the water later
C.a(chǎn)re 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.

Have you ever heard the story of the four-minute miles? Many years ago, people believed that it was impossible for a human Being to run a mile in less than four minutes until Roger Banister proved it wrong in 1954.
What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when someone, who doesn't know how to swim, falls in deep waters? They drown. If an animal who has not learnt swimming could escape by swimming, why not you? Because you believe you will drown while the animal doesn't.
Have you ever wondered why the letters are organized in a particular order on your keyboard? You might have thought it is to increase the typing speed. Most people never question it. But the fact is that this system was developed to reduce the typing speed at a time when typewriter parts would jam(堵塞) if the operator typed too fast.
These three cases show the power of our beliefs. There is no other more powerful directing force in human behavior than belief. Your beliefs have the power to create and to destroy. A belief delivers command to your nervous system.
I used a snake in my workshops for children to show them how unrealistic some of their beliefs are. Students of a school in India, said snakes are slippery and slimy and poisonous.
