About 25 million auto accidents occur in the United States each year. Approximately 5 million people are injured in these accidents; some 50,000 are killed. Auto insurance of course cannot reduce the deaths, the injuries, or the damages, and it does offer protection against the financial risks of auto ownership and operation.(1)____
The principle decisions to be made by auto insurance buyers are what coverage to buy, what amounts of insurance to buy, and what agent and company to buy.(2)____(3)____
Auto liability coverage is essential. No one should drive a car without protection against the potential high cost of lawsuits.(4)____ In some U.S. states liability insurance is required by law. Because of the size of lawsuits cannot be predicted, there is no way to know in advancement how much protection will be needed.(5)____(6)____ In deciding upon the amount, consumers should realize that the extra cost of high limits is relatively small. Double the cost of the limits, for example, does not double the cost of the protection.(7)____ Agents should be asked the cost of several different limits for the buyer to choose among. Reasonably high amounts of liability protection should be a high priority objective.

If the protection is needed, higher amounts should be purchased.

答案解析

文章大意
本文讨论了美国的汽车保险。本文介绍了美国的交通事故现状，说明汽车保险虽然不能减少事故的发生，但是能给汽车所有权和营运的经挤风险提供保护。本文还介绍了汽车车主在购买车险时，需主要考虑的是购买的车险种类、金额以及向哪家保险公司购买。最后，详细介绍了两种车险：汽车责任险和汽车医疗险。其中，汽车责任险是最关键的。在美国的某些州，责任险是法律规定车主必须强行购买的一种车险。
答案详解
1．and→but语篇错误。前半句捉到“汽车保险不能减少事故的发生”，后半句表明“汽车保险能给汽车所有权和营运的经济风险提供保护”。两分句之间是转折关系，and是并列连词，but是转折连词，因此要将and改为but。
2．principle→principal词汇错误。此灶考查形近词的辨析。principle为名词，意为“原则，道义；基本信念”，放在此处不符合上下文语义。principal作形容词时， 表示“主要的，首要的”，此处修饰名词decisions，整句意为“购买车险时，车主主要要做的几个决定是——购买的车险种类、金额以及向哪家保险公司购买。”
3．(to) buy∧→from语接错误。此处若缺少from，表示的则是“要买哪家代理商和公司”的意思，显然与语境不符，这里应该表示“从哪家代理商或公司购买车险”，buy sth. from sb.为固定搭配，意思为“向……购买……”，因此要增加from。
4．potential→potentially语法错误。此处是用来修饰后面的形容词high，所以要改为potential的副词形式potentially。
5．of→of词汇错误。because是连词，引导原因状语从句，because of也是表示原因，但是后面接名词或代词。此处后接一个完整的句子，故应该去掉。直接用because来引导。整句意为“因为诉讼案件的大小无法被预估，所以也无法提前得知将会需要多少保护。”
6．advancement→advance词汇错误。advancement是名词，意思为“前进；促进”，advance可以用作名词、动词或形容诃，在这里和in构成固定搭配，in advance意思为“
提前”。
7．Double→Doubling语法错误。此句中for example为插入语，遮住不看可发现，此处缺主语，将Double改成其动名词形式，则动名词短语Doubling the cost of the limits作为整句的主语，谓语是does not double．此句意为“例如，将限额的成本翻倍，保护金也不会升至两倍”。
8．most→least语篇错误。前句提到跟责任险相比，医疗险不如责任险那么重要。此句后半部分表明在那些制定了强制有效的无过失汽车法的州里，人身伤害保护险（PIP）能提供足够的资金来支付医疗支出。可以看出前后句的意思一致，都是说明医疗险的重要性不大。故此处要将most改为least。
9．necessary→unnecessary语篇错误。由上文可推出，医疗险在无过失法则的保护下，重要性不大。同样，对购买了足够的医疗艟康保险的人来说，汽车医疗险也不是必要的。因此要将necessary改为其反义词unnecessary。
10. has→have语法错误。who引导定语从旬，其先行词是people而不是insurance，people表示复数含义，因此要将has改为have。
