　　mobile phones are more important than ever in the daily lives of students, but how they use them has changed greatly in the past six years. while phones are still widely use for communication, a recent study has found that most students think talking on mobile phones is now old-fashioned.
　　london university researchers surveyed 1055 young people aged 13 to 18 about their mobile phone habits. the researchers pided mobile phone use into ＂communication＂ and ＂entertainment＂. communication included talking on the phone and writing messages using texting（短信）or chatting software. entertainment was made up of playing games, watching movies, listening to music and surfing the internet. the findings were then compared to a XX study, to see what changed. the results are shown below:
　　perhaps most surprising is how little time students spend talking on their phones these days. six years ago the average student spent 36% of their mobile phone time making or receiving calls. in XX, only 10% of time was used for talking. when students use their phones to communicate, more and more often it is done by using chat software like qq or we chat.
　　＂communication is still an important function of mobile phones. but now mobile phones are being used more for entertainment than for communication,＂ said dr harry lectre, the research leader.
　　1. what was the most popular mobile phone activity in XX?
　　a. talking. b. texting.
　　c. playing games. d. watching movies.
　　2. in total, what percentage of time did students use their mobile phones for communication in XX?
　　a. 16%. b. 28%. c. 35%. d. 71%.
　　3. which of the following is true about watching movies on mobile phones?
　　a. it has increased most over the past six years.

　　c. it was the most popular type of mobile phone entertainment in XX.
　　d. students now spend more time watching movies than talking on their phones.
　　4. which mobile phone activities were more popular than surfing the internet in XX?

　　how quickly can you count from one to ten? do you use ten different words to do it? can you do it in english, or do you have to use your first languages? do you count on your fingers? many people think that numbers and math are the same all over the world. but scientists have discovered that it is not true.
　　people in different parts of the world use different ways to count on their fingers. in the united states, people think begin counting with their first fingers, which they extend or stick out. they then extend the rest of their fingers and finally the thumb(拇指）to count to five. then they repeat this with the other hand to get to ten. in china, people count by using different finger positions. in this way, a chinese person can easily count to ten on only one hand.
　　besides ways of finger counting, scientists have found that cultures and languages are also different when it comes to numbers. some languages have only a few words for numbers, and others have no words for numbers. a group of scientists studied aboriginal(土著的）people in australia. these people don’t have hand movements to stand for numbers. they don’t even have word for numbers. however, they are still able to understand different ideas about numbers.
　　in a similar study, researchers from the massachusetts institute of technology discovered that people of the piraha tribe(部落） in northwestern brazil don’t have words for numbers such as ＂one＂ or ＂three.＂. they are not able to say ＂five trees＂ or ＂ten trees＂ but can say ＂some trees,＂ ＂more trees,＂ or ＂many trees.＂ professor edward gibson said that mist people believe that everyone knows how to count, ＂but here is a group that does not count. they could learn, but it’s not useful in their culture, so they’ve never picked it up.＂
　　although all humans are able to understand quantities(数量）,not all languages have numbers and not all people use counting. number words in a certain language are a result of people needing numbers in their daily lives. now we know that people have different ideas about numbers and math, too.

　　how green are you? do you know how to be green?
　　we all need a healthy environment, but we produce waste every day and it does harm to our environment. though we are young, we can still do something to help. in fact, even the simplest everyday activities can make a real difference to the environment. here are some ideas for you.
　　reduce
　　reduce means ＂use less＂. don’t waste things. this saves money and reduces pollution and waste going into the environment. before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! when we do buy things, choose local products if possible, and try not to buy too many things from abroad.
　　reuse
　　reuse means ＂use again＂. use things for as long as possible. when we buy things, make sure that they last a long time. we should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. don’t use a paper cup of a paper bag. it’s better to use a china cup and a lunch box because you can use them again.
　　recycle
　　recycle means ＂change things into something else＂. though it takes energy to change something into something else, it’s better than throwing things away or burning them. find out what can be recycled in your neighbourhood and take part in recycling programmes. we should also buy products made from recycled materials, such as recycled paper, to help save trees.
　　so please remember these three words: reduce, reuse and recycle.
　　1.what is the passage about?
　　a.how to produce things. b.how to burn things.
　　c.how to help others. d.how to be green.
　　2.which of the following is right?
　　a.don’t waste things. b.always throw away old things.
　　c.always buy new things. d.buy too many things from abroad.
　　3.why is it better to use a china cup and a lunch box?
　　a.you can burn them.
　　b.you can use them again.
　　c.you can throw them away.
　　d.you can change them into something else.
　　4.to protect the environment, we should remember these three words: _______.
　　a.waste, reuse and recycle b.repair, burn and recycle
　　c.reduce, reuse and recycle d.reduce, waste and recycle.
　　5.the passage may come from ______.
