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.
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.Why do the tadpoles hatch up to 2 days ahead of the schedule?Because
A. They like falling into the water early
B. They want to grow into adult frog
C. They sense a hungry snake is about to attack
D. Frog embryos can grow strong
4.What is the best title of the passage ?
A. What is Fear B. Why do we feel afraid
C. You feel afraid,animals do too D. Fear is a good thing
5.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.

A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be "running out of control". This idea is dangerous.
Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast and is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.
Some people go even further. They say that despite the moral and legal objections, whatever is scientifically possible will be done-somewhere , sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it fuels a sense of hopelessness and discourages then from making efforts to build a safer world.
In our interconnected world, the lack of agreement in and out of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of "controlling" science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.
Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the untied efforts of people with hope, can we be fully safe against the misuse of science and can
science best serve mankind in the future.
1.What can we conclude from the recent study?
A. People think highly of science.
B. People hold mixed opinions about science.
C. Science is getting dangerously out of control.
D. Science is used for both good and bad purposes.
2.According to the passage, what will happen if we hold that science is getting beyond control?
A. The development of science will hopelessly slow down.
B. Businesses will have even greater influence on science.
C. The public will lose faith in bringing about a bright future.
D. People will work more actively to put science under control.
3.The discussion should reach beyond scientific societies because _____.
A. scientists have failed to predict the outcomes
B. the ties between different areas need strengthening
C. united efforts are necessary for the development of science
D. people need to work together to prevent the bad use of science
4.What is the main idea of the passage?
A. Science and its applications bring us many dangers.
B. The development of science mostly lies in people's attitudes.
C. Mankind can largely take control of science with their efforts.
D. The future of science will be influenced by the dangerous ideas.
