4.In a computer age,a broadband Internet connection is very popular now.Whether cable or mobile broadband,today's connections are many times faster than those in the early days.Videos play smoothly,complex websites load quickly,and files download much faster than ten years ago.And the files are much bigger too.
There's a hidden problem:You have to live near enough to a major city to get broadband Internet.If you don't,it's slow dial-up access for you.And for those living really far out,there may be no Internet access at a11.
Technology experts often talk about the"last mile"problem,which refers to the difficulty of bringing Internet access to remote locations.In cities and suburbs(郊區(qū)),it's relatively easy to provide access for everyone.It is much more difficult to deliver access to those living far from cities,especially in developing countries.Internet service providers.for their part,have been reluctant to provide access to sparsely(稀疏地)populated areas.The handful of Internet users they would reach wouldn't cover the expense.
But every year,technological advancements allow of more and more Internet users.Most broadband connections today run over existing cable TV and telephone lines although these technologies aren't available everywhere.
Some companies have delivered the Internet over standard power lines.Advancements in cheaper more efficient fiber optics cables(光纖電纜)promise to bring extremely fast Internet connections to more users.Still.the"last mile"problem remains hard to deal with.There will always be somewhere that doesn't have an affordable broadband connection.But someday that might not matter.If the rapid progress in cell phone technology is any indication,it may not be too long before an Internet connection simply follows you wherever you go.

分析 本文講述當(dāng)代網(wǎng)絡(luò)連接發(fā)展十分迅速,無(wú)論是播放或是下載都得到大大提速,然而背后仍然隱藏著"最后一米"的問(wèn)題即:邊遠(yuǎn)地區(qū)網(wǎng)絡(luò)權(quán)限的問(wèn)題.但手機(jī)技術(shù)的迅速發(fā)展使得將來(lái)這一問(wèn)題的解決成為可能.
解答 29.C.推理判斷題.由文章第二段experts often talk about the"last mile"problem,which refers to the difficulty of bringingInternet access to remote locations.技術(shù)專(zhuān)家經(jīng)常談?wù)撟詈笠幻椎膯?wèn)題,即將網(wǎng)絡(luò)權(quán)限帶給邊遠(yuǎn)地區(qū),可知網(wǎng)絡(luò)權(quán)限的問(wèn)題還未完全解決,故選C.
30.D.細(xì)節(jié)理解題.由第四段advancements allow of more and more Internet users技術(shù)進(jìn)步允許更多的網(wǎng)絡(luò)使用者,可知這一段主要就是講技術(shù)進(jìn)步使越來(lái)越多的人使用網(wǎng)絡(luò),故選D.
31.B.推理判斷題.由文章最后一句the rapid progress in cell phone technology is any indication,it may not be too long before anInternet connection simply follows you wherever you go.如果手機(jī)技術(shù)的迅速發(fā)展是一個(gè)征兆,無(wú)論你去哪里都會(huì)有網(wǎng)絡(luò)連接不會(huì)太久,可知手機(jī)技術(shù)的迅速發(fā)展最終會(huì)解決最后一米的問(wèn)題,故選B.
32.A.標(biāo)題歸納題.文章主要介紹了在如今的電腦時(shí)代,仍然存在網(wǎng)絡(luò)連接不上的問(wèn)題,作者分析了原因,并給出了可能解決的辦法.故選A.
點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí),要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷.
