New Energy in the Twenty-first Century Energy from the wind.
All over the world, people use the power of the wind. It is a clean source of energy, and there is lots of it. But if the wind does not blow, there is no wind energy.
Energy from the water
When water moves from a high place to a lower place it has the power to make electricity. In Britain, waterpower produces enough energy to power a town with 40000 people. Waterpower gives energy without pollution, but people have to build dams(大壩) to use this kind of power, and building dams is very expensive.
Energy from the earth
There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地?zé)岬? San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.
Energy from the sun
Solar panels(鑲板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful, but when the weather is bad, it can’t produce power.

What’s the best way to remember our happiest moments, like a birthday or festival? I bet you would answer , “Take lots of photos!” Well, here is a great surprise. People who always take photos may actually be harming(傷害) their memory, because they’re not concentrating on the event itself. That’s according to new research by Fairfield University, Connecticut, in the US. They call this the “photo-taking impairment(損害) affect”.
“People so often take out their cameras almost mindlessly to catch a moment, to the point that they are missing what is happening right in front of them,” Henkel and her team decided to perform an experiment. They wanted to find out whether taking photos in a museum weakened(減弱) a visitor’s memory of what they had seen. So they simply told a group to look around the museum, and either take photos of the items on display, or try to remember what they had seen. In addition(另外), the amount(數(shù)量) of detail(細(xì)節(jié)) they remembered was worse than those who didn’t take photos. “These results show how the mind’s eye and the camera’s eye are not the same,” said Henkel.
But don’t put your camera down just yet. Other studies have found that looking back at old photos helps us remember an event, compared to just taking a photo and forgetting about it. So next time you’re thinking of taking a photo, just think: is it better to look at the beauty around you with your own eyes, or behind the eye of the camera?
小題1: When we take photos, we _________.
A．fail to focus on the event itself
B．can’t record the details
C．remember what we have seen
D．a(chǎn)re likely to have a poor memory
小題2:Which of the following is NOT true about the experiment?
A．People who didn’t take photos did better in the experiment.
B．They asked a group to try to remember what they had seen.
C．The experiment aimed to learn what people were interested in at the museum.
D．People who took photos in the museum could remember less details.
小題3:According to the passage, we’d better _________.
A．never use our cameras
B．remember an event by heart
C．a(chǎn)lways remember an event with the help of a camera
D．see everything only with our own eyes
小題4:What do the results of the experiment show us?
A．The mind’s eye and the camera’s eye are not the same.
B．People remember happiest moments by taking photos.
C．Looking back at old photos helps us remember an event.
D．People don’t like taking photos.
小題5:Where can we probably read this passage?
A．The entrance of a museum.
B．A guidebook on how to take good pictures.
C．An instruction of how to use a camera.
D．A scientific report.

If you’ve tried studying when you’re tired, you know that it can seem very impossible to do well.
A study of sleep in sparrows suggests the relationship between sleep and the ability to learn may be more complicated(復(fù)雜) than people knew.
Niels C·Rattenborg, a scientist from Wisconsin-Madison, wanted to find out how the sparrows were able to deal with getting so much less sleep. He and his team brought eight wild birds into a lab and watched them for one year. They invented a game to check how well the birds could learn. In the game, the sparrows had to peck(啄)three buttons （按鈕）in a right order to get a food treat. The scientists discovered that the birds’  ability to learn the right button order depended on(依靠)two things: the time of year and the amount of sleep the birds had had.
During the migration（遷徙）season, the sparrows were restless at night and got much less sleep than usual. Even so, they were able to understand how to get the food quickly as if they’d had a regular night of sleep. Outside the migration season, they found the sparrows that got less sleep than usual had much more difficulty learning how to get the food treats than birds that had a regular sleep.
The results show that the sparrows can deal with much less sleep during the migration season than usual. If scientists can find out why, they may learn from sparrows and find ways of helping people deal with getting much less sleep. Until scientists fully understand the relationship between sleep and learning, it’s better to get plenty of sleep when preparing for an exam.
小題1:The passage is mainly about          .
A．sparrows’ migration.
B．sleep lessons from Sparrows.
C．how to get less sleep while studying
D．how sparrows that got less sleep get food treats
小題2:Why can sparrows get much less sleep during the migration season?
A．They eat more.
B．The climate is better
C．They can get food quickly
D．Scientists still don’t know the reason.
小題3:What fact does the passage lead you to believe?
A．We should sleep as little as sparrows do.
B．We should get enough sleep before an exam.
C．When tired, we should try to focus on(聚焦) our study.
D．When tired, we should check how we can sleep less than usual.

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.
Polluted air from cars, planes and factories is so thick that it is like a quilt(被子) over a city. This kind of quilt is called smog(煙霧). Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away. And they mustn’t blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
