Question

20．Sunny countries are often poor．A shame，then，that solar power is still quite expensive．Eight 19，a British company by Cambridge University，has，however，invented a novel way to get round this．In return for a deposit of around dollar 10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity，a battery that can deliver a three amp（安培） current to store this electricity，and a lamp whose bulb is a light-emitting diode（二極管）．The firm thinks that this system，once the battery is fully charged，is enough to light two small rooms and to power a mobile-phone charger for seven hours．Then，next day，it can be put outside and charged back up again．
The trick is that，to be able to use the electricity，the system's keeper must buy a scratch card-for as little as a dollar-on which is printed a reference number．The keeper sends this reference，plus the serial number of the household solar unit，by SMS to Eight19．The company's server will respond automatically with an access code to the unit．
Users may consider that they are paying an hourly rate for their electricity．In fact，they are paying off the cost of the unit．After buying around dollar 80 worth of scratch cards-which Eight19 expects would take the average family around 18 months-the user will own it．He will then have the option of continuing to use it for nothing，or of trading it in for a bigger one，perhaps driven by a 10-watt solar cell．
In that case，he would go then through the same process again，paying off the additional cost of the upgraded kit at a slightly higher rate．Users would therefore increase their electricity supply steadily and affordably．
According to Eight 19's figures，this looks like a good deal for customers．The firm believes the average energy-starved Kenyan spends around dollar 10 a month on oil-enough to fuel a couple of smoky lamps-plus dollar 2 on charging his mobile phone in the market-place．Regular users of one of Eight19's basic solar units will spend around half that，before owning it completely．Meanwhile，as the cost of solar technology falls，it should get even cheaper．

41．The underlined word"get round"in the first paragraph can be replaced byD．
A．make use of       B．come up with        C．look into       D．deal with
42．What should the user do when the electricity in the battery is used up？B
A．Buy a scratch card．
B．Recharge it outside．
C．Buy another solar cell．
D．Return it to the company．
43．How much would users pay for the cell and scratch cards before they own a 2.5-watt solar cell？C
A．Around 10． B．Around  80． C．Around 90． D．Around 180．
44．It can be inferred from the last paragraph thatB．
A．Kenyan families would find it difficult to afford the solar cell
B．using the solar cell would help Kenyan families save money
C．few Kenyan families use mobile phones for lack of electricity
D．the company will make a great profit from selling solar cells
45．What might be the most suitable title for the passage？A
A．Solar Energy：Starting from Scratch．
B．Eight19：a creative British Company．
C．Kenyan Families：Using Solar Energy for Free．
D．Poor Countries：Beginning to Use Solar Energy．

解答 41-45  DBCBA
41   D   推理題．根據(jù)文章1，2行Sunny countries are often poor．A shame，then，that solar power is still quite expensive．Eight19，a British company by Cambridge University，has，however，invented a novel way to get round this．可知這些有陽光的國家通常都比較貧窮，現(xiàn)在英國的這家公司找到一個方法來處理這一問題，故D項正確．
42   B  細(xì)節(jié)題．根據(jù)第一段最后3行The firm thinks that this system，once the battery is fully charged，is enough to light two small rooms and to power a mobile-phone charger for seven hours．Then，next day，it can be put outside and charged back up again．可知可以重新充電，故B正確．
43   C  細(xì)節(jié)題．根據(jù)文章1，3段In return for a deposit of around 10itissupplyingpoorKenyanfamilieswithasolarcellabletogenerate2.5wattsofelectricity，和Afterbuyingaround80 worth of scratch cards-which Eight19 expects would take the average family around 18 months-the user will own it．說明一共要付90美元，故C正確．
44   B  推斷題．根據(jù)文章最后一段According to Eight19's figures，this looks like a good deal for customers．The firm believes the average energy-starved Kenyan spends around 10amonthonoil-enoughtofuelacoupleofsmokylamps-plus2 on charging his mobile phone in the market-place．說明肯尼亞人也可以從中獲益，故B正確．
45  A   主旨大意題．本文主要討論的是英國的一家公司對太陽能的一種新的運作的方法，故A正確．

點評 本文主要討論的是英國的一家公司對太陽能的一種新的運作的方法．本文考查細(xì)節(jié)題為主，細(xì)節(jié)題可以在文章中直接找到與答案有關(guān)的信息？或是其變體．搜查信息在閱讀中非常重要它包括理解作者在敘述某事時使用的具體事實、數(shù)據(jù)、圖表等細(xì)節(jié)信息．在一篇短文里大部分篇幅都屬于這類圍繞主體展開的細(xì)節(jié)．做這類題一般采用尋讀法？即先讀題，然后帶著問題快速閱讀短文，找出與問題有關(guān)的詞語或句子，再對相關(guān)部分進(jìn)行分析對比，找出答案．
