(10 points) 0 Not so long ago, it was the stuff of nightmares: you pick up the landline telephone and theres no dialing tone. Nothing. The pho
2、ne is useless,【C1】_in your hand. For most of the 20th century, this was a horror film stereotype, a symbol of isolation and【C2】_foretold.But just 15 years later, the death of the landline is close to being a【C3】_and one entirely of our own making. BT has announced plans to【C4】_charges for landline c
3、alls, in a bid to maintain commercial feasibility for landline services. The move suggests that BTwhich has long【C5】_landlines over mobile calls may have given up on turning back the clock. In the US, the【C6】_of households that have mobile phone connection but no landline has risen to a quarter. The
4、 most recent research in the UK, put the【C7】_figure at 15%.For millions of todays twentysomethings, who have had a mobile number since their teens and for whom a landline makes no【C8】_sense during the transient years before they settle down, the moment of【C9】_into land-line-owning may never come【C10

12、n the best silicon solar cellsby far the most【C1】_sortconvert only a quarter of the light that falls on them. Silicon has the【C2】_of being cheap: manufacturing improvements have brought its price to a point where it is snapping at the heels of fossil fuels.【C3】_many scientists would like to replace
13、it【C4】_something fundamentally better.John Rogers, of the University of Illinois, Urbana-Champaign, is one. The cells he has【C5】_can convert 42.5% of sunlight.【C6】_improved, Dr Rogers reckons, their efficiency could rise to 50%. Their【C7】_is that they are actually not one cell, but four, stacked one
14、 on top of another.Solar cells are made of semiconductors, and every type of semiconductor has a【C8】_called a band gap that is different from that of other semiconductors. The band gap【C9】_the longest wavelength of light a semiconductor can absorb (it is transparent to longer wavelengths). It also f
15、ixes the【C10】_amount of energy that can be【C11 】 _from shorter wavelength. The result is that long-wavelength photons are lost and short-wave ones incompletely utilised.Dr Rogers【 C12】_this by using a different material for each layer of the stack. He chooses his materials【C13】_the bottom of the ban
16、d gap of the top layer matches the top of the band gap of the one underneath, and so on【C14】_the stack. Each layer thus【C15】_off part of the spectrum, converts it efficiently into electrical energy and passes the rest on.The problem is that the materials needed to make these semiconductors are【 C16】
17、_But Dr Rogers has found a way to overcome this.【 C17】 _solar-cell modules are completely covered by semiconductor, but in his only 0.1% of the surface is so covered. The semiconducting stacks, each half a millimeter square, are【C18 】_over that surface many dots. Each stack then has a pair of cheap
18、glass lenses【C19】_over it. These focus the suns light onto the stack, meaning that all【C20】_light meets a semiconductor.21 【C1 】（A）conventional（B） common（C） peculiar（D）humble22 【C2 】（A）merit（B） effect（C） accessory（D）bonus23 【C3 】（A）But（B） Because（C） So（D）Also24 【C4 】（A）as（B） to（C） for（D）with25 【C5 】
