1.D 第一段的mirror出现在The school bus is a mirror of the community，further add that, unfortunately, what appears on the exterior does not always reflect the reality of a chosen community. 这里的mirror就是reflect的名词形式reflection。
2.A 细节题，第四段This year he will celebrate 30 years working for Althouse Bus Company，告诉了答案。
3.C 关于Bruce Hardy的说法错误的是，我们还是定位在第四段话的第三句话，也就是Larry Althouse的话中，通过对比就知道C项的说法是错误的。
4.B Althouse Bus Company 是由谁建立的，倒数第二段的第二句My grandfather started the business with one bus.标明是由说话者的祖父建立的，而说话者就是Althouse further，这在Althouse further adds中体现出来了。
5.D 最后一段话体现了Althouse Bus Company公司对于建立良好的关系是相当重视的。Thanks to drivers like Bruce Hardy, they have been building relationships through generations.是最好的体现。
6. A 如果不认识threaten一词就要在原文中找到该单词所在的句子，通过对句子的理解来确定单词的意思。原句是threatened animals such as elephants 比如大象一类的...动物。endangered是处于危险中的，frightened是可怕的，killed被杀的，angered是生气的、发怒的，由此可见最为接近的应该是frightened。
7. B estimate是估算，by 在这里是方法、方式的意思，为什么研究者们在某些地区用计算粪便的方法来估算大象的数量。Counting elephants from planes is impossible in the vast rainforests of Central Africa. So researchers often estimate elephant numbers by counting dung piles in a given area. 所以答案是B.
8. C relied on意思是依赖、依靠。They also need to know the rate at which dung decays: Because it's extremely difficult to determine these rates...But researchers at the WCS have found that this decay rate varies from region to region depending on the climate and environment.可见因为不同地方的大象粪便的腐化频率是不一样的，所以导致依靠计算大象粪便来计算大象数量的方法变得很不靠谱。
9. D 在原文中找关于Plumptre的叙述，倒数第二段Plumptre also says that the dung-pile census should be carried out over a region similar in size to an elephant's natural range.所答案显而易见了
10.A 在文中找到这句话，He and his colleague Anthony Chifu Nchanji studied decaying elephant dung in the forests of Cameroon.这里的he肯定是和上段文字连接，前一段话末尾是...says Plumptre.可见这里的he就是指上文的Plumptre。
11.C 原文第一段When Patricia Rochester decided to go back to school after ten years as a staff nurse at Toronto Western Hospital, her employer not only cheered her on, but also paid her tuition and gave her a day off with pay every week to study. cheer...on意思是为...欢呼，为...鼓劲加油。
12.D ease one's stiffness and stress 消除（减轻）某人的顽固和压力，题干中问的是原文中没有提到...那我们就将stiffness and stress还原到文中，And if staffers feel stiff and stressed from too many hours on the ward, they can call for a free 15-minute shoulder-and-neck massage （按摩） or even sign up for an eight-week evening course on meditation skills and stress-relief....这段文字是相对应的说明，只要一一对应就可以选出文中没有提到的选项
13.B Investment in staff 这里有一个if引导的条件状语从句来If such initiatives help companies cut down on turnover （人员更替） alone, they're well worthwhile.所以这里对员工的投资是为了减少人员的流动。
14.A Innovative initiatives help companies attract talented employees, cut down on sick days （which cost Canadian businesses an estimated $17 billion a year, or an average of $3,550 per employee）加拿大花了巨资引进人才，课件最缺的就是人才。
15.C If that's not enough, employees can take advantage of five family days a year that can be used if the kids come down with the flu or an aging parent needs ferrying to an important doctor's appointment.这里是kids come down with the flu，flu是流感的意思，这里员工利用一年5天的家庭假期肯定是孩子得了流感的情况下，所以这里的come down with意思最接近选项C get.
