There are far too many road accidents in this country,too manydeaths and too many people injured. One wonders who aremost to blame, drivers and pedestrians.__1__ Some people saythat the blame cannot be put fairly　with considering the stateof the roads and the whole __2__ transport system. In suchcrowed cities London,__3__ Birmingham or Manchester, roadconditions are so　chaotic that both driver and pedestrian oftenendanger　lives through no fault of their own. Such sufficiency__4__ as too many road signs,faulty traffic lights, suddenly　narrowing of the streets, congested parking are all a sure indicationof bad road conditions. On the other hand, many experts are convincing that the larger__5__part of the blame for the death toll must be put on　persons alone: Drivers who drive too fast andwithout any consideration for others; drivers who think they　are safe at the wheel as thoughthey have drunk too__6__ much alcohol; drivers, who out of some curious sense　of power, areincapable of understanding that their car　is a lethal weapon if is improperly used. Pedestrians, __7__ likewise, must share the guilt-stepping off the　pavement without first looking to the left orright,crossing roads when the traffic lights are for them,__8__ jump off a moving bus. To be fair,pedestrians, drivers__9__ and road conditions are all to blame. One looks forward to the day whenthe motor-car has been　replaced by some more dangerous means of transport.__10__
    參考答案及解析:
    1. and—or。根據(jù)上下文One wonders who are most to blame這一疑問，drivers和pedestrians其中之一需負(fù)責(zé)任
    2. with—without。without引導(dǎo)一個(gè)條件狀語從句：“如果不考慮路況和整個(gè)交通體系的話”
    3. 在London前加as。such...as結(jié)構(gòu)
    4.sufficiency—deficiencies。deficiencies意義為一些“不足，缺陷”，下文列舉的too many road signs, faulty traffic lights, suddenly narrowing of the streets,congested parking都是路況的不足和缺陷
    5. convincing—convinced。下文that從句后列舉司機(jī)和行人種種的違規(guī)的行為不得不使人信服(convinced)the larger part of the blame for the death toll must be put on persons alone
    6. as—even或刪除as。as though引導(dǎo)條件狀語從句;even though引導(dǎo)讓步狀語從句，意義為“即使”，此處是“有些司機(jī)即使喝了很多酒，他們?nèi)匀徽J(rèn)為自己能夠把握住方向盤”
    7. 去掉is或在is前加it。根據(jù)語法規(guī)則，有些表示時(shí)間、地點(diǎn)、條件、方式或讓步狀語從句，如果謂語包含有動(dòng)詞be，主語又和主語的主語一致，那么常?？梢园褟木渲械闹髡Z和謂語部分，特別是動(dòng)詞be省略掉
    10. for—against。步行者應(yīng)該承擔(dān)責(zé)任的原因之一為交通信號(hào)燈不讓他們穿越馬路時(shí)他們卻穿馬路了
    9. jump—jumping。jumping與上文的stepping off，crossing 并列和一致，應(yīng)該用動(dòng)名詞
    10. more—less。從上下文邏輯和意義判斷
