If it looks like a fish and swims like a fish, it usually is a fish. But not the new, lifelike robot fish developed by UK scientists, which have been swimming around the London Aquarium(水族館) as they wait for their release off northern Spain in 2011.

Equipped with tiny chemical sensors(傳感器),the fish will collect data on pollution in the port of Gijón and wirelessly send the information back to the control center. “It’s a little lab onboard the fish,” said Rory Doyle, a scientist at BMT Group. The robots were designed, and are being built, by professor Huosheng Hu and his team at the University of Essex, UK.

The sensors will search for dangers such as chemical waste and will allow officials to map in real time the sources and effects of pollution, Doyle said.

He and his colleagues chose a fish design because hundreds of millions of years of evolution(進(jìn)化) has created an energy-efficient creature, he said. “Nature has done it very, very well.” But copying such a successful design comes at a cost: nearly 29,000 u.s. dollars per robot. w w w.k s 5 u.c o mThe fish, therefore, will be built “robust” enough to handle any possibilities, Doyle said. They can’t get caught in nets easily, for instance, and the tracking systems inside can help the robot fish avoid crashes with boats and other things in the way.

So far, it also seems unlikely the robot fish will be mistaken: At the London Aquarium, sharks swim away from the fake fish, possibly because they find the robots electromagnetic fields(電磁場(chǎng)) unpleasant, Doyle said.

At the same time, scientists are working to ensure that the sounds of the robots and other factors don’t disturb the natural environment, he added.

64.The robot fish was developed in order to_______.

A.be displayed on a robot exhibition in Spain

B.be sent to London Aquarium as a gift

C.get information of ocean pollution

D.collect data on the fishes in deep sea

65.According to Doyle, the robot was designed into fish shape in order to_______.

A.cut the cost of the robot

B.make the robot beautiful

C.reduce the sounds of the robot

D.make the robot work better with less energy

66.We can infer from the passage that the robot fish______.

A.would send pictures of sea life back

B.would not be looked on as a real fish by fishes

C.could swim much faster than fishes like sharks

D.could help find new forms of energy in the sea

67.The underlined word “robust” in Paragraph 6 probably means_____.

A.small and light    B.big and heavy

C.smooth and soft    D.strong and smart

    Let’s do some sleep math.You lost two hours of sleep every night last week because of a big project due on Friday.On Saturday and Sunday,you slept in,getting four extra hours.On Monday morning,you were feeling so bright—eyed that you only had one cup of coffee,instead of your usual two.But don’t be cheated by your energy.You’re still carrying around a heavy load of sleepiness,or what experts call “sleep debt”一in this case something like six hours,almost a full night’s sleep.

    Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get.It’s a shortage that grows every time we skim some extra minutes off our nightly sleep.“People get more sleep debt gradually without being noticed,”says William C.Dement,founder of the Stanford University Sleep Clinic.Studies show that such short term sleep lack leads to a foggy brain,worsened vision,and trouble remembering.Long-term effects include obesity(肥胖),insulin(胰島素)resistance,and heart disease.A survey by the National Sleep Foundation reports that we’re losing one hour of sleep each night——more than two full weeks of sleep every year.

  The good news is that,like all debt,with some work,sleep debt can be repaid.Adding all extra hour or two of sleep a night is the way to catch up.For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern.

  Go to bed when you are tired,and allow your body to wake you in the morning(no alarm clock allowed).You may find yourself catatonic(有緊張癥的)in the beginning of the recovery cycle:expect to have ten hours shut—eye per night;As the days pass,however,the amount of sleeping time will gradually decrease.

  So earn back that lost sleep and follow the rules of your innate(固有的)sleep needs. You’ll feel better.“When you put away sleep debt,you become a superman,”says Stanford's Dement,talking about the improved mental and physical capabilities that come with being well rested.

53.If rou have short-term sleep lack,you may          .   

  A.put on weight    B.get heart disease

  C.hate eating food D.have a poor sight

54.The example of sleep math is used to show         

  A.in what case you build up a sleep debt

  B.in what way you can make up for lack of sleep

  C.why you are energetic even without enough sleep

  D.why you need six hours’sleep every night

55.By saying the underlined sentence,Dement means that         

  A.you need a lot of sleep to be a superman

  B.you will be in a good state with enough sleep

  C.you need to be a superman to repay sleep debt   

  D.you will become a superman with more sleep debt

56.What might be the most suitable title for the passage?   

  A.How can you keep energetic?    B.What is sleep debt?

  C.Can you catch up on lost sleep?D.Can coffee refresh you?

科目: 來(lái)源: 題型:閱讀理解

The house was quiet at 5 am and Tim' s mother was asleep. Only the sound of the big freezer broke the quiet. He’d dreamt of the cave last night. The purring (輕微顫動(dòng)聲) of the freezer had been the sea.

Tim pulled on a sweater and put some apples into his schoolbag. It was too early for breakfast. He'd eat after he’d been through the cave, sitting on the rocks and staring at the sea.

He wished he had a proper pack. His schoolbag would have to do. What else? Sandwiches---but his mother might wake up if he started pulling out bread for sandwiches, she' d want to know why he had to leave so early. He settled for some biscuits, and left a note stuck to the table:

Gone to Michael’s. Back tonight, Tim.

The sky was high and soft and light outside, though the sun still wasn't up. Even the highway up the hill was quiet as he made his way down the street. The wind from the sea was fresh and sweet.

The sandhills still breathed heat from yesterday’s sun, though the top of the sand was cool. He ran down to the beach impatiently, but there was no one, just dry sand dancing in the early wind and seabirds marching up and down watching the waves. O%

The light changed suddenly. The first rays of sunlight stretched (延伸) across the sea. The sun was pushing its way over the edge of the world.

Over the first rocks, along to the point. Tim glanced back. The beach was still empty. The sun sailed higher in the sky.

He could see the cave now, even darker in the morning light. The sand turned silver then dark gold as the water flowed away from it. He had to force himself to go closer. Why was it so much more mysterious (神秘的) now? But it would be silly to go back now after so much trouble. He needn't go in all the way. . .

63. What did Tim do at the beginning of the story?

A. He left the house quietly.      B. He had breakfast at home.

C. He left a note on the freezer.  D. He put a sweater in his schoolbag.

64. "He settled for some biscuits” ( in Paragraph 3 ) means that Tim_______.

A. had to leave the biscuits on the table         B. liked biscuits better than sandwiches

C. had to take biscuits instead of sandwiches  

D. could only find some biscuits in the kitchen

65. What made it possible for Tim to see the entry to the cave?

A. The height of the first rocks.                 B. The ups and downs of the waves.

C. The change in the position of the sun.     D. The vast stretch of the sunlit beach.

66. In the story, Tim's mood (心情) changed from_________.

A. loneliness to craziness                         B. anxiousness to excitement

C. helplessness to happiness                      D. eagerness to nervousness

How to be a good listener

Everyone loves a good listener. But there are more reasons to develop the skill of listening than to win hearts or popularity contests.

Listening heals hurts and builds bridges. It gives us the ability to understand and empathize, to view the world from our own point. It can bring us wisdom over and above mere intelligence. But most importantly, it allows us to give the people around us the gifts they crave (渴望) most—a sense of worth.

As it turns out, there’s more to good listening than just keeping quiet and allowing someone to speak. Effective listening is actually a combination of two key communication skills: listening and verifying (確認(rèn)).

Even when we’ve managed to hear a person’s entire message, we often interpret it wrong—according to our own understanding, experience, or prejudice.

As an effective listener, your goal is to hear and absorb what another has to say……in exactly the way they mean it to be understood. Only then can you respond properly.

This is much easier read than done, so here are a few helpful tips:

1.Give the speaker your full attention.

Stop talking and remove all distractions. Turn off the TV, your phone, or computer. Watch your body language. The way you look at the speaker, or the way you stand or sit, makes a huge difference. The right listening body language communicates that we are listening openly and attentively, and puts the other person at ease.

2.Be patient.

Not everyone is a gifted speaker. Some people take longer to find the right word to make a point. Others are too worried to get their message across properly. If necessary, ask the speaker to explain further. It will help him / her speak more exactly and it will help you hear and understand better.

3.Keep your emotions in check.

If what someone is saying creates an emotional response in you, make an extra effort to listen carefully. When we’re angry, frightened or upset, we often miss key parts of what is being said.

4.Hold your fire.

Don’t jump to conclusions immediately. A good listener doesn’t react until comprehension is complete. If you respond in a way that makes the other person defensive, even if you “win” the argument, you may lose something far more valuable.

5.Even if you think you understand. VERIFY.

Never assume you got the message right. Pause, think about what was said, and then ask “Is this what you meant?” or “Am I understanding this right?”

6.Empathize

Take a moment to stand in the other person’s shoes, to look at the situation from his / her point of view……especially when you’re being told something personal or painful, or something you strongly disagree with. The more shoes you are able to successfully stand in within your life time, the less puzzled you’ll find your life and relationships to be.
