文章大意：这是一篇说明文。本文介绍了把火星改造成蓝色的“生命天堂”的宏伟规划，综述了科学家对这个火星改造工程所持的不同观点。
1 . The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth.
This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers. This suggests the future for the "red planet" will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event.
Turning Mars into a little earth has long been a topic in science fiction,” said Dr Michael Meyer, NASA's senior scientist for astrobiology (太空生物学)．“Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”
Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.
But many experts are shocked by the idea. "We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet," said Paul Murdin from the Institute of Astronomy, Cambridge, UK.
Over the past months, scientists have become increasingly confident .They will find Martian life forms. Europe and America's robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.
1. The passage is about________.
2. Those who agree to turn Mars into a little earth______.
3. What’s Paul Murdin’s attitude to the plan?
4. What can we know about the scientists from the last paragraph?

2 . Modern smart phones are fast becoming the must-have item. But what’s in store for the next generation of smart phones?
Tired of carrying around that heavy wallet? Soon you won’t need to! The next generation of smart phones will have NFC technology, which lets you pay for things with your smart phones. All you do is enter your credit card information into your phone. Then, when you are in a shop that allows NFC payments, you just wave your phone over a special instrument at the checkout. The purchase is instantly charged to your credit card.
Ever seen someone wearing something and wished you knew where to get it? Soon it will be easy with PicCommerce, new technology that uses image-recognition software. Here’s how it works. If you see something you like, simply take a photo of it with your smart phone. Then, your phone will send the image to a special server, which will respond with information about where you can buy it and how much it will cost.
Sick of your smart phone battery going flat? With so many applications draining (消耗) the battery, the latest phones need to be charged every day. But next generation smart phones will come with built-in chips that can connect to an antenna (天线) in your home. And as long as your phone is within range of the antenna, you will be able to charge your smartphone wirelessly, even if it is in your pocket.
Worried about getting your smart phones wet in the rain? A company called Hz0 has invented WaterBlock, new technology that makes your phone completely waterproof. And it’s so effective that your phone will even work underwater.
Fed up with carrying a heavy phone around? Soon, you will be able to get a PaperPhone! “Flexible phones are the future,” said scientist Roel Vertegaal. So, what are the benefits of flexible phones? Well, it means that instead of carrying your phone in your pocket, you could wear it wrapped around your wrist, for example.
Of course, there is just the problem: with so much new smart phone technology around, you will soon need to buy a new phone!
