Section Ⅱ Reading Comprehension

Madrid was hailed as a public health beacon last November when it rolled out ambitious restrictions on the most polluting cars. Seven months and one election day later, a new conservative city council suspended enforcement of the clean air zone, a first step toward its possible demise.

Mayor Jose Luis Martinez -Almeida made opposition to the zone a centrepiece of his election campaign, despite its success in improving air quality. A judge has now overruled the city \'s decision to stop levying fines, ordering them reinstated. But with legal battles ahead, the zone\'s future looks uncertain at best.

Among other weaknesses, the measures cities must employ when left to tackle dirty air on their own are politically contentious, and therefore vulnerable. That s because they inevitably put the costs of cleaning the air on to individual drivers一who must pay fees or buy better vehicles 一rather than on to the car manufacturers whose cheating is the real cause of our toxic pollution.

It\'s not hard to imagine a similar reversal happening in London. The new ultra-low emission zone (Ulez) is likely to be a big issue in next year\'s mayoral election. And if Sadiq Khan wins and extends it to the North and South Circular roads in 2021 as he intends, it is sure to spark intense opposition from the far larger number of motorists who will then be affected.

It\'s not that measures such as London\'s Ulez are useless. Far from it. Local officials are using the levers that are available to them to safeguard residents\' health in the face of a serious threat. The zones do deliver some improvements to air quality, and the science tells us that means real health benefits - fewer heart attacks, strokes and premature births, less cancer, dementia and asthma. Fewer untimely deaths.

But mayors and councillors can only do so much about a problem that is far bigger than any one city or town. They are acting because national governments一Britain s and others across Europe - have failed to do so.

Restrictions that keep highly polluting cars out of certain areas - city centres, 。school streets", even individual roads - are a response to the absence of a larger effort to properly enforce existing regulations and require auto companies to bring their vehicles into compliance. Wales has introduced special low speed limits to minimise pollution. We re doing everything but insist that manufacturers clean up their cars.

31. Which of the following is true about Madrid\'s clean air zone?

[A] Its effects are questionable

[B]It has been opposed by a judge

[C] It needs tougher enforcement

[D] Its fate is yet to be decided

32. Which is considered a weakness of the city-level measures to tackle dirty air?

[A] They are biased against car manufacturers.

[B] They prove impractical for city councils.

[C] They are deemed too mild for politicians.

D] They put too much burden on individual motorists.

33. The author believes that the extension of London\'s Ulez will .

[A] arouse strong resistance.

[B] ensure Khan\'s electoral success.

[C] improve the city s traffic.

[D] discourage car manufacturing.

34. Who does the author think should have addressed the problem?

[A] Local residents

[B]Mayors.

[C] Councilors.

[D] National governments.

35. It can be inferred from the last paragraph that auto companies.

[A] will raise low-emission car production

[B]should be forced to follow regulations

[C] will upgrade the design of their vehicles

[D] should be put under public supervision

男性，65岁，持续性上腹部疼痛半年，消瘦、贫血、乏力，偶有恶心、呕吐。查体呈贫血貌，上腹部剑突下轻压痛。应采用哪种辅助检查确定诊断
A. X线上消化道造影 B.血清胃泌素测定
C. B超检査 D.纤维胃镜检查

答案：D

解析：

[考点]消化道疾病的检查 [分析]病人高龄，病程达半年，伴消瘦、贫血等危险因素，首先应除外胃癌，选择胃镜检查。本项检查直观、安全，既可作定位诊断，又可作定性诊断，特别是可以通过活组织病理学检查证实。X线上消化道造影诊断的假阳性和假阴性率均较胃镜检查为高，故准确性不如内镜检查。B超对空腔器官病变的准确性更差。血清胃泌素检查不具特异性，不能作为定性诊断的检查手段。

女性，30岁。右下腹痛已4日，恶心、厌食，发热，体温38°C左右。查体：右下腹饱满，可及一压痛性包块，边界不清楚，固定。査血白细胞12X109/L。
该患者的诊断应考虑是

A.急性输卵管炎
B.阑尾周围脓肿
C.Crohn病
D.回盲部肠结核其治疗是

答案：B

解析：

[考点]阑尾周围脓肿[分析]女性病人，右下腹痛巳4天，伴消化道症状，发热，白细胞高，右下腹有压痛性肿块，固定，边界不清，应想到阑尾周围脓肿。病变的阑尾被大网膜包裹黏连，炎症被局限。Crohn病和肠结核可发生在回盲部，也可有压痛性肿块，但均为慢性病，病史长，有低热、腹泻等，白细胞计数也不会高。输卵管急性炎症压痛偏低，常伴腰痛，还可有白带多等妇科体征。阑尾周围脓肿的治疗不应立即手术，因为炎症已局限，病情相对稳定，应选用广谱抗生素治疗，待炎症消退后再择期手术。但应密切观察病人，如炎症有扩散，则应及时处理。
