Users can download"Google WiFi" software and then enjoy free WiFi service available in some US cities since last Tuesday. WiFi is short for "Wireless Fidelity" （无线上网）. It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio signal. A person with a WiFi enabled computer can connect to the Internet when near one of the network's access points. The place covered by one or several access points is called a hotspot Google has already set up two "hotspots" in the US city of San Francisco which provide a free WiFi service. The WiFi technology even allows users to enjoy a free Internet phone service. Some scientists argue that WiFi may replace mobile phone networks. WiFi is still limited to a few cities，where there are "hotspots". But its capability（容量） of sending information has already done better than that of the mobile phone network, even that of 3G （3rd generation telecommunication technology). Some scientists have started to call WiFi 4G. In addition to a high speed Internet connection，WiFi has other advantages compared to mobile phones. WiFi is global. The same WiFi system works in different countries around the world. Different from using cell phones，you don't need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all. 1. WiFi is not available in cities without ______ ． A. a computer B. a radio C. a hotspot D. a cell phone 2. Which of the following is NOT the advantage of WiFi？ ______ A. The high speed Internet connection． B. Many free Internet phones． C. Using the same computers for Internet phones． D. Used in all the US cities． 3. Some scientists started to call WiFi 4G，because ______ ． A. it is the product of the Google's 4th generation B. it is more capable of sending information than the mobile phone network C. it has been used by more than four generations D. WiFi will surely take the place of the mobile phone network 4. Which of the following is the BEST title？ ______
A. Third Generation Telecommunication Technology B Free Call Service C. Google Launches Free WiFi Service D. Google, King of the Web B A scientist working at her lab bench and a six-old baby playing with his food might seem to have little in common. After all, the scientist is engaged in serious research to uncover the very nature of the physical world, and the baby is, well, just playing.right? Perhaps, but some developmental psychologists(心理学家) have argued that this"play" is more like a scientific investigation than one might think Take a closer look at the baby playing at the table. Each time the bowl of rice is pushed over the table edge, it falls in the ground---and, in the process, it brings out important evidence about how physical objects interact(相互作用); bowls of rice do not float in mid-are, but require support to remain stable. It is likely that babies are not born knowing this basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby's investigation and the scientist's experiment appear to share the same aim( to learn about the natural world overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?) Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has for example, unlike the child, mommy actually doesn,'t like dove chocolate Viewing childhood development as a scientific investigation throws light on how children learn but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, " It is not that children are little scientists but that scientists are big children 5. According to some developmental psychologists A. a baby's play is nothing more than a game B. scientific research into babies: games is possible 第2页,共8页

I strongly argue in favor of the addition of more computers We have to think about a greater goal and a more practical way to enhance the quality of life for students. Do we want our college to be known as a place with a great bookstore where you can find CDs and gifts, or as a place where the students can research in their field using the best tools provided by technology As a learning institution, this college has the responsibility to offer its students the best technology to help them prepare for their future, since many students will be expected to be familiar with the latest software and other tools when they go on to work. While they are in college, students find they are expected to use computers. They are asked to create Power Point presentations and research many topics on the Internet. Being able to do a computer would be much more difficult to find. Since students are competing for good grades, those who have limited access to computers are at a great disadvantage

If there are more new and faster computers accessible, students will be able to complete ther work more efficiently. No more will they have to wait in line, paper and disk in hand, while scanning the room for an empty chair and computer. No longer will they have to sit and wait while an outdated computer struggles to follow their commands The more computers are used in society, the more colleges will depend on them as a tool of teaching and learning. Making computers more accessible to students facilitates their learning process by making it much easier and more engaging(tiE), and eventually improves their quality of life 10.
