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.
D.How tree frogs improve their chances of survival before falling into the water.

Speaking in public is most people’s least favorite thing. The reason is that we are all afraid of making fool of ourselves. .
But stop biting your finger-nails. Public speaking is easy. It’s just plain talking, and you talk all the time. Although I’m basically shy (honest!). I’ve been making speeches and talking on radio and television for more than 30 years. And I can tell you that public speaking is not a “gift” like musical talent , so .Here are some of the lessons I have learned:
Your audience is going to go away with one or two of your main ideas.One or two.Not ten or twenty. .And if you don't have a clear idea of what you want to say, there's no way your audience will. —how you are going to open, what major points you want to make and how you're going to close.
When I do a radio or TV piece, I often write the last sentence first. .A strong close is critical; the last thing you say is what your audience will most likely remember.
The standard length of a audio-visual act is usually 12 minutes.If all those performers singing and dancing their hearts out couldn't go on longer without boring the audience, what makes you think you can?
A. Some people are born to be good at making speech |
B. Anybody who can talk can speak in public |
C. Try to relax yourself before making the speech |
D. The more important the speech is, the more frightened we become |
E. If you can't express in a sentence or two what you intend to get across, then your speech is not focused well enough. |
F. When you know where you're heading, you can choose any route to get there |
G. No matter how long or short your speech is, you've got to get your ideas organized. |

Five steps to take if your child is being bullied
51 The worst thing you can do is ignore it. Too often parents feel children and teens need to “work things out” on their own. If the problem is ignored, your child’s self-esteem will become unhealthy, he will be hurt mentally or physically, and he could become a bully himself.
Here are five steps you can take if your child is having problems with a bully:
52 This is an important first step and will help your child trust that you are able to help him with his problem. Accept what he has to say at face value by using your active listening skills.
Let your child know that he is not alone. 53 Reassure your child that he is not the problem. Nothing he did caused the bully to go after him.
If your child is being threatened in a physical or illegal way at school, report the problem. Your child may not want you to do this, or the school may not take it seriously, but violence cannot be tolerated. 54 You will need to model assertive (果断的) behavior by alerting those in charge where the bullying is taking place.
Teach your child assertive behavior and how to ignore routine teasing. Let them know it is okay to say “No.” sometimes even friends bully, so letting your child know they can be true to their own feelings and say “No” can go a long way.
55 Giving up possessions or giving in to a bully in anyway encourages the bully to continue. Identify ways for your child to respond to a bully---showing assertive but not aggressive behavior---and role-play them.
A. Believe what your child tells you.
B. Encourage your child not to give in to a bully.
C. Praise your child for being brave enough to talk about it.
D. Bullying is a terrible situation for a child to have to cope with.
E. If you choose not to do anything, that is what you’re teaching your child.
F. Most children have to deal with some type of bullying behavior at one time or another.
G. If your child comes to you because a bully is bothering him, you need to pay close attention to the problem.
