The Book of Life
So far, scientists have named about 1.8 million living species(物种), and that’s just a small number of what probably exists on Earth. With so many plants, animals, and other living things coveting the planet, it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by.
A soon-to-be-started Web site might help. An international team of researchers has announced the creation of Web-based Encyclopedia(百科全书) of Life ( EoL). The project aims to list every species on Earth in a single, easy-to-use reference guide.
To get the encyclopedia started, the creators will use information from scientific databases (数据库) that already exist. And eventually, in special sections of the site, non-scientists with specialized knowledge will come to help. Bird-watchers, for example, will be able to input what birds they’ve seen and where. To make sure the encyclopedia is accurate, scientists will review much of the information added to it.
As the EoL develops, you might find it useful for school projects. The site will feature (以……为特色) special pages for kids who are studying ecosystems in their neighborhoods. Another convenient feature of the EoL is that you’ll be able to pick the level of detail you want to see to match your interests, age, and knowledge.
It now takes years for scientists to collect all the data they need to describe and analyze species. The creators of the Encyclopedia of Life hope that their new tool will speed up that process.
【小题1】The Web-based EoL aims to__________ .

A.find out what covers the earth
B.list all living things on Earth
C.work out the number of birds
D.save the existing plants
【小题2】One characteristic of the EoL is that__________ .
A.it is run by school students
B.it focuses on different types of grass
C.it provides different levels of information
D.it allows non-scientists to review its data
【小题3】In the last paragraph, "that process" means__________ .
A.analyzing species B.creating a new tool
C.collecting dataD.describing species

I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?”? He looked perturbed (不安). “Do you want to try it first?” he said. It didn’t quite sound like a question. “Do I need to?” I replied ,“There is nothing wrong with it?” This made him look a bit insulted and I started to feel bad. “No, no. But you should try it,” he said encouragingly. “Compare it with the others. ”
I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.
But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out of my chosen camera from cupboard, show how it took excellent pictures of my fellow shoppers… and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.
Why do we think that new options still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.
【小题1】The shop assistant insisted that the writer should________.

A.try the camera to see if there was anything wrong with it.
B.compare the camera he had chosen with the others.
C.get more information about different companies.
D.trust him and stop asking questions.
【小题2】What does the writer mean by “it would be worth half what I paid for it ”(paragraph 2)
A.He should get a 50% discount.
B.The price of the camera was unreasonably high.
C.The quality of the camera was not good.
D.The camera would soon fall in value.
【小题3】 The writer decided to try the model he had chosen because he________.
A.knew very little about it.
B.didn’t trust the shop assistant
C.wanted to make sure the one he chose would be the best.
D.had a special interest in taking pictures of his fellow shoppers.
【小题4】It can be inferred from the passage that in the writer’s opinion__________.
A.people waste too much money on cameras
B.cameras have become an important part of our daily life
C.we don’t actually need so many choices when buying a product
D.famous companies care more about profit than quality

“Any time! Any where! Decades ago there was no such thing” – “Communication”.
Then, September 7th 1987, the global system for mobile communication or GSM was born. And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry.
To be honest, the world’s first mobiles were not so attractive and the range of effectiveness wasn’t very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work.
There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that’s not all.
20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet.
“The phone itself is involved from just being a communication tool, to be a tool for round-the-clock connectivity, you can not live without it even in a minute.” Mobile consultant Nick Lane also points out with so many customized styles and features, your mobile phone will become a symbol of you.
Where will the global mobile phone industry be in another 20 years? Certainly, there will be more connections than better coverage. As for where else technology will take us, one can only imagine.
【小题1】According the passage, we can know that GSM is ____________.

A.a global-used mobile phone B.a global mobile phone industry
C.a global mobile phone associationD.a global mobile communication system
【小题2】It's most difficult to find a CDMA mobile phone in ____________.
A.the United StatesB.South AmericaC.EuropeD.China
【小题3】From this passage, we can infer that ____________.
A.as soon as the first mobiles appeared, they became popular and many people have one
B.with a GSM mobile phone, you can make a phone call in most parts of the USA
C.there are only two cell phone systems in the whole world: GSM and CDMA
D.most of the mobile phone users in the world now are using the GSM mobile phone
【小题4】By pointing out “your mobile phone will become a symbol of you”, what does Nick Lane want to tell us about the mobile phone in the future?
A.You can have a mobile phone with the unique look and functions as you like.
B.Others can find us without any difficulties if we carry our mobile phone.
C.The mobile phone can be used as a permit when you enter some places.
D.The mobile phone we carry can show others how wealthy we are.
【小题5】What does the writer feel about the GSM development in the following 20 years?
A.Satisfied.  B.Worried.  C.Confident.  D.Confused.
