STEVE Wayne, 16, who worked this summer as a lifeguard and swim teacher in Idaho Falls, was thrilled to see an extra $20 in his paycheck when the federal minimum wage increased in July.

“When you’re getting paid minimum wage, anything helps, ” Wayne said.Wayne is one of several hundred thousand American teenagers who earn the minimum wage. The last of three recent increases that took the minimum from $5.15 an hour in 2007 to $7.25.U.S. Secretary of Labor Hilda Solis says the minimum-wage increase will pump an extra $5.5 billion into the economy over the next year, which is helpful at a time when the economy is hurting.

"You're giving people who spend money a raise," says Kai Filion of the Economic Policy Institute. "Those people will go out and spend that money, and it will circulate through the economy."

But other economists say raising the minimum wage actually hurts the very people it's designed to help. A higher hourly minimum, they say, could force businesses to cut workers' hours, or even lay people off.

"What matters for people earning minimum wage is how much money they take home, in total, in their paycheck," explains Rajeev of Georgia State University's Economic Forecasting Center. "Their hourly rate may go up, but their number of hours may come down, so it's not an overall increase."

Business owners also say that raising the minimum wage exerts(施加)upward pressure on other wages. "If the minimum wage is $7 and I have to pay $8 or $9 to hire a dishwasher, then the cooks are going to say they want more," sayd Cleveland restaurant owner Rick. "How much can I charge for that hamburger?"

Another argument is that it makes it more expensive for businesses to hire new workers. For many businesses already struggling to make ends meet in these tough times, it will be simply too expensive to keep or to hire new people.

55.Steve Wayne was excited that_____________ .

A.his hard work had paid off

B.he had received a big wage increase

C.he has more money due to an increase in minimum wage

56.According to the text, the US federal government has increased minimum wage with the aim of__________

A.decreasing unemployment

B.promoting economic recovery

C.increasing American teenagers’ wage

D.narrowing the gap between the rich and the poor

57.What matters most to people in need of help is_____________.

A.a higher hourly minimum       B.more working hours

C.a minimum-wage increase      D.an increase in total income

58.Some are against the increase in minimum wage because they say_____________.

A.only very few workers will be helped

B.they have to cut down working hours

C.many business owners can’t afford to employ new workers

D.minimum wage workers will expect more pay rises in the future

(二) 阅读下面短文,回答下 * * 道题。
尘埃无处不有,虽然它们的个体很小,但汇聚起来威力却不小。据记载,北美大陆在20世纪30年代发生的一次尘暴中,狂风将美国平原的泥土大量向东吹去,有难以估计的牲畜被尘埃窒息而死。尽管如此,尘埃的积极作用却是不可低估的。悬浮在大气中的尘埃粒子,能够将太阳光中的较短光柱拦截,使其进行有规则的发散,这样,才会使天空呈现蔚蓝,在太阳升起和降落时,由于阳光穿过较低层的空间,空气中的尘埃密度大,并伴有水汽,可以吸收和反射阳光中的黄色和红色部分,因此,这时看到的太阳呈现橙色、红色和黄色。气象学家指出,在降雨时,每一个雨滴都必须有一颗尘埃参与,以它作为核心,水汽在其周围凝结,形成云、雾,再由云层形成雨点。若是纯净的空气中没有尘埃的存在,水分子无所依附,就不能形成雨滴降落。此外阳光在射向地球的时候,因受到尘埃的吸收和反射,能使地球上的生物得到适量的光照,以满足生长发育所需要。
现代科学发现,有的尘埃在一定的条件下会发生爆炸,这种现象被称作“尘炸”。据解析,能够产生尘炸的物质有粮食粉尘、砂糖、奶粉、咖啡、金属粉末以及其他非金属粉末等。物质发生爆炸,是一种剧烈的化学反应。而化学反应的速度与反应物质的颗粒大小有关。物质分散得越细,颗粒越小,它的表面积就越大。与具有固定面积的物质相比,接触空气吸附氧分子多,氧化和放热的过程都很快,反应性能就更活泼。当其中的某一质点被火点燃,就会发生连锁反应,产生爆炸。此外,易爆尘埃的颗粒越细,浓度越大,它所产生的爆炸力就会越强。当粉尘含量低于大气含氧量一半时,就不会引起爆炸,物质形成“尘炸”,还和诱因、速度等因素有关。产生“尘炸”的诱因很多,其中最主要的是摩擦冲击以及电器设备或静电产生的火花。
随着现代城市的迅速发展,人们发现尘埃已经成为一种危及环境和人类健康的污染物。流行病学家对尘埃进入人体后的机理进行研究后指出,人们在呼吸时,每次大约要吸入50万个浮游微粒;这些微粒进入人的身体后,可以一直进入肺部深处,并作为经常性刺激物留在那里,它会导致发生炎症,产生黏液,使人呼吸困难,甚至导致死亡的发生。除此之外,浮游微粒还可以向肺部传送化学污染物,而且在传送过程中,可以加速一种叫做游离基的有害物质的产生,从而进一步加剧有害物质对人体的危害程度。进入人体内的浮游微粒尘埃,主要来源于工业废弃物、汽车尾气及建筑、装饰材料中的化学成分。资料表明,在我们生活环境内排放的浮游微粒70%来自人为因素。另据调查,哮喘病、肺炎、心脏病等疾病的发病率,都与浮游微粒的增减有关。

下列对“尘炸”现象的表述不正确的一项是( )。

A.砂糖、面粉、铝粉、铁粉、咖啡、干奶粉等都是能产生“尘炸”的物质

B.易爆尘埃分散得越细,颗粒越小,表面积就越大,反应性能就更活泼,产生“尘炸”的可能性就越大

C.“尘炸”的威力与物质分散的颗粒大小有关:颗粒越大,尘埃的浓度也就越大,“尘弹”的威力也越大

D.产生“尘炸”的诱因最主要的是摩擦冲击以及电器设备或静电产生的火花
