阅读理解 A mobile phone is no longer just a phone -- it is also a music player, video camera and personal organizer. And mobile phones with television programming are just around the corner. But the more functions cell phone manufacturers add, the greater the amount of power the phones use and the less practical running them on lithium (锂) batteries becomes -- so the race to find a viable alternative is on. Two of the world's biggest electronics makers, Hitachi and Toshiba, are currently competing against each other to come up with an alternative, most likely to be micro fuel cells. The task has been set by Japan's second largest mobile phone provider, KDDI, which wants its customers to soon be able to use special television programming on their handsets, and has asked the two electronics companies to come up with a better power source. Hitomi Murakami, of KDDI, says battery-operated mobile phones cannot keep up with the new applications. We're looking at various ways to expand content and services that we can provide to the people. And we don't want to have battery issues delaying us from doing that, he says. Hitachi's Atsushi Morihara says it is a critical race for both of the companies as the resulting product will have a major impact on the mobile market in the future. We are in competition and it's up to both of us to come up with a good product. A product that will satisfy KDDI's needs. I think I can go as far to say that the winner will take all. Miniaturized direct methanol (甲醇) fuel cells are different batteries in that they create power instead of simply storing it. That power is made by new technology utilizing cheap methanol. If all gees to plan, come 2007, Japanese phone users will not use an electric charger to power their mobiles, they will instead carry a small bottle of methanol and with just a few squirts, they will have power for their phones. But the method has its downsides, including how passengers will be able to take small mounts of flammable methanol on airliners. Fumio Ueno of Toshiba says that once developed, the uses of miniaturized direct methanol fuel cells have endless possibilities.1.The lithium batteries are becoming improper for the cell phone because ______.A.there is a television in the phoneB.it is inconvenient to useC.it can't provide enough powerD.people have found substitutes2.According to the passage, Toshiba ______.A.is in critical competition with KDDIB.will probably beat its rivalC.attaches great importance to methanol fuelD.is one of the largest battery provider3.Which of the following is NOT the characteristic of methanol fuel?A.Easy to catch fire.B.Portable.C.Inexpensive.D.Available everywhere.4.The best title for the passage is ______.A.Search for better phone power.B.Development of cell phone battery.C.Competition between two electronic firms.D.Advantage and disadvantage of methanol fuel.

BCDA解析1.本题问“为什么锂电变得越来越不适合手机使用?”文章第一段中第三句提到“But the more functions cell phone manufacturers add，the greater the amount of power the phones use and the less practical running them on lithium batteries becomes”也就是说，生产商给移动电话附加的功能越多，电话所需要的能量越大，所以锂电就越来越缺乏实用性。由此可知B“它不能够提供足够的能量”正确。A“正电话上有电视”。文中是说“television program”，而不是电视机。C“它不方便使用”。文中只说“... the less practical running them on lithium batteries becomes”，与不方便使用的意思不同。D“人们已经找到了替代物”。两家公司还在研究，尚未找到合适的替代物。2.本题问“根据文章内容，可以对东芝公司做出怎样的推断?”文章最后一段中的最后一句提到“Fumio Ueno of Toshiba says that once developed，the uses of miniaturized direct methanol fuel cells have endless possibilities.”也就是说，东芝公司认为这种替代物一旦被开发出来，甲醇燃料将会有很大的潜力。也就是说东芝公司对这项发明很重视。所以C“东芝对开发甲醛燃料非常重视”正确。A“与KDDI公司竞争很激烈”。文中是说“Japan's second largest mobile phone provider，KDDI”，即KDDI公司是日本第二大手机供应商，而不是生产商，所以他们之间不存在激烈竞争。B“将会击败对手”。文中未提及。D“东芝是最大的电池供应商之一”。文章只提到了它是“electronics makers”，即最大的电器制造商，是否为最大的电池供应商文中未提及。3.本题问“下面哪一项不属于甲醇燃料的特点?”综合全文内容，可以判断D“可以随处得到不属于甲醛的特性”，文中没有相关的阐述，为本题的
