1、考研英语二（完形填空）模拟试卷 135及答案解析(总分：120.00，做题时间：90 分钟)一、Use of English(总题数：3，分数：120.00)1.Section I Use of EnglishDirections: Read the following text. Choose the best word(s) for each numbered blank and mark A, B, C or D.（分数：40.00）_Not so long ago, it was the stuff of nightmares: you pick up the landline tel

2、ephone and theres no dialing tone. Nothing. The phone 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.

3、BT has announced plans to【C4】_charges for landline calls, in a bid to maintain commercial feasibility for landline services. The move suggests that BTwhich has long【C5】_landlines over mobile callsmay have given up on turning back the clock. In the US, the【C6】_of households that have mobile phone con

4、nection but no landline has risen to a quarter. The 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 mo

What【C11】_does it make whether the cables lie underground or not? A lot,【C12】_. The death of the landline

6、 is a cultural【C13】_that affects our personal and public lives. It has separated us【C14】_our groupingsin the office, where email has disconnected us from what the people who sit three feet away do all day, and even more【C15】_, at home. In any household in the days before mobiles【C16】_, the landline

7、served as a switchboard for everyones connections outside the home.【C17】_families, couples, roommates, it was a kind of【C18】_knowledge map about the state of everyones romantic and social lives, and one we took for granted. And【C19】_though we are to our mobiles, most of the time we arent talking but

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 semi

15、conductors. The band gap【C9】_the longest wavelength of light a semiconductor can absorb (it is transparent to longer wavelengths). It also fixes 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 ut

He chooses his materials【C13】_the bottom of the band 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

17、 efficiently into electrical energy and passes the rest on. The problem is that the materials needed to make these semiconductors are【C16】_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 covere

18、d. The semiconducting stacks, each half a millimeter square, are【C18】_over that surface many dots. Each stack then has a pair of cheap glass lenses【C19】_over it. These focus the suns light onto the stack, meaning that all【C20】_light meets a semiconductor.（分数：40.00）(1).【C1】（分数：2.00）A.conventionalB.co
