Napoga is a 12—year---old girl in Ghana, Africa. It is hard for her family to get clean water . Every morning , she leaves home at half past five to get clean water for her family in a village far away . It takes her six hours to get enough clean water for daily cooking and drinking. She has no time to go to school or to play with her friends. Millions of people in the world are like Napoga . They can’t get enough clean water to keep healthy.
Earth Day is April 22. But on all other days, we must also remember it. The water we use is the most important natural resource(自然资源)on the earth.
Water covers 70 perent of the earth’s surface (表面). But most of that is sea water. We can’t use it for very many things. Fresh water covers only one percent of the earth’s surface.
You probably feel lucky that your life isn’t as hard as Napoga’s . But that doesn’t mean you don’t have to worry about water. We all face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers , lakes , and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish , too. Now, thirty-four percent of all kinds of fish are dying out.
How do cars and factories make our water dirty? First, they pollute the air. Then , when it rains, the rain water comes down and makes our drinking water dirty. Dirty rain, called acid rain(酸雨), is also bad for plants ,animals and buildings.
Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save more water for ourselves and our children. Here is some advice for saving water:
● Turn off the water while you brush your teeth. You can save as much as 450liters(升)each month.
● Leaky taps （漏水的龙头）waste a lot of water. Fix them right away.
●You can easily cut your 10—minute showers in half---and you’ll be just as clean.
●When you wash dishes, don’t let the water run.
●Only wash clothes when you have a lot to wash. If your washing machine isn’t full , you are wasting water!

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(伤害) 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(损害) 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(减弱) 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(数量) of detail(细节) 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?
| A．fail to focus on the event itself |
| B．can’t record the details |
| C．remember what we have seen |
| D．are likely to have a poor memory |
| 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. |
| A．never use our cameras |
| B．remember an event by heart |
| C．always remember an event with the help of a camera |
| D．see everything only with our own eyes |
| 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. |
| 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. |

Millions of British people have ditched the traditional “thank you” and took the place of it with the less formal “cheers”, according to a survey.
Although the common person will say “thank you” nearly 5,000 times a year, one in three are more likely to add a “cheers” or “ta” where it’s needed to show they are fashionable.
One in twenty now say “nice one” instead, while the younger are more likely to offer a “cool” than a “thank you”.
“Merci”, “fab” and even “gracias” were also listed as common phrases to use, as “much appreciated(感激)”.
One in twenty who took part in the survey of 2,000 people by the Food Network UK for Thank You Day, which is marked on November 24, 2011, said a formal “thank you” was now not often needed in everyday conversation. More than one in ten adults said they regularly won’t say thank you if they are in a bad mood. Most people stated that saying thank you was something that their parents trained them. A huge 70 percent of those questioned will say thank you to a person’s face without even meaning it, while one fifth avoid(避免)saying it when they know they should.
It seems our friends and family get the stress of our bad manners. Half of them admit (承认) they’re not good at thanking those closest to them. Many of them explain that they don’t say thank you because their family “already know I’m grateful”.
When spoken words won’t do, it falls to a nice text to do the job for most people.
One third will still send a handwritten thank-you note---but 45 percent admit it’s been more than six months since they tried to send one.
A quarter of British people say “thank you” with food, with 23 percent cooking a meal to show their appreciation to someone. Another 15 percent bake a cake.
It follows that 85 percent of people will be angry because of not getting the gratitude (感激)
they feel they should receive.
| A．when they are in good mood |
| B．completely out of habit |
| C．when they feel truly grateful |
| D．purely out of politeness |
| A．gave up | B．used |
| C．shared | D．knew |
| A．different ways of expressing gratitude are all fashionable |
| B．people should avoid saying “thank you” nowadays |
| C．a thank-you note is still appreciated by most people |
| D．people in a bad mood never say “thank you” |
| A．Most people express their gratitude to others by buying food for them. |
| B．About fifty percent of people try not to say thank you when they should. |
| C．Most people may feel natural when they fail to receive others’ gratitude. |
| D．Many people think it unnecessary to say thanks to their family members. |
It seems that there’s a good reason why dogs are always seen as man’s best friend. Scientists have found that dogs are the only animals that can read emotion(情感)in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.
When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person’s face first. A possible reason for this is that the right side of the human face is better at expressing emotions.
Scientists have now shown that pet dogs also have “left gaze bias(左视偏好)”, but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs’ eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs.
Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.
“Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first.”
| A．Because dogs are the closest animals to humans. |
| B．Because dogs can read the emotions in humans’ faces easily. |
| C．Because dogs can understand us better when we feel sad. |
| D．Because dogs are good at expressing emotions. |
| A．get along well with humans |
| B．express emotions quickly |
| C．have more understanding friends |
| D．remember more new faces |
| A．dogs have been man’s best friends for thousands of years |
| B．humans have a “left gaze bias” |
| C．the “left gaze bias” works on all animals |
| D．dogs can read emotions the same as humans |
Do you want to know something about children in Africa? What do they do for fun every day? Find out here:
Education
School is expensive for many African children. Lots of families can’t afford school uniforms or exercise books even though they don’t have to pay for school.
For those lucky enough to go to school, they have a lot to learn. Some take two language classes: English or French, and their first languages. There is also math, science, history and geography. Chores take up much of children’s time after school. They have to get water and firewood for the family every day. Also there’s cleaning, washing and helping Mum with the meal.
Daily fun
It’s not all work and no play.Sports are very popular. Children can make goals with twigs（嫩枝）and their own footballs with plastic and bits of string(绳子).They play in the country and the streets of old towns.There’re many football teams for teenagers in Africa.
Internet
It’s really expensive to get on the Internet. To surf the net for 20 hours costs 600yuan.This is more than the average（平均的） monthly pay per person.
