Ⅱ.阅读理解
Banff National Park is Canada's first national park. In 1883, on the Canadian Rocky Mountains, three railway workers discovered a natural hot spring, and from there the park was born. Nowadays, it is one of the world's popular tourist spots with great mountain scenery. Every year, millions of people visit it for its wonderful views.
Banff National Park is part of UNESCO's Canadian Rocky Mountain World Heritage site. Located in the heart of the Canadian Rockies, the park has perfect mountains like those on postcards. They are from 45 to 120 million years old, with the highest in the park, Mount Forbes, coming in at 11,850 feet.
Banff National Park is 80 miles west of Calgary. Calgary's international airport is serviced by major national and international carriers with many flights arriving daily. Open year-round, it offers amazing wildlife viewing and sightseeing, plus many shopping and dining choices, any time of the year. Summer is popular for hiking, mountain biking and cycling, photography, and climbing. The best time for viewing the seasonal color is fall, when the trees turn yellow.
In winter, the mountain makes exciting downhill (速降) and cross-country skiing. In fact, three major downhill ski resorts (度假胜地)
operate within the park. Lake Louise Ski Resort, Sunshine Village, and Mount Norquay combine to offer a large area for skiing, not to mention the backcountry trails available throughout the park. The ski season, which runs from November to May, is one of the longest in North America. Visitors can also enjoy wildlife tours, ice walks, and dogsleds (雪橇)．Weather in the Canadian Rockies can change quickly. A single day can have a mix of sunshine, snow, wind, and rain, so you should change your clothes. In summer, temperatures average a high of 70(21 ℃), and daylight lasts until 11 p．m. Autumn brings cool nights and fresh air. Winters can be very cold. In January, the average temperature is 7 ℃ below zero, but by April it is 9 ℃.

Ⅲ.七选五
Air pollution, as we know today, started with the Industrial Revolution in Europe in the 19th century. In the last few decades, it has become the major problem of our environment. __1__ It may also cause harm to other living things such as animals and food crops.
Our modern life style has led to dirtier air over the years. Factories, vehicles of all kinds, and the growing number of people are the things that are responsible for air pollution today. __2__ Forest fires and dust storms can also lead to the pollution of the atmosphere.
There are two types of ozone (臭氧) that we know of. __3__ But on the ground, people produce ozone, too. Traffic and factories cause ground ozone. It is especially dangerous for children and older people.
__4__ Choosing other forms of energy, like solar energy or wind energy could be helpful in controlling pollution. Cities like London have shown that better air quality can be achieved in a short time.
Smog is a combination of smoke and fog (雾). During the beginning of the Industrial Revolution, thousands of people died in London every year. However, a lot has been done to prevent smog recently. Factories use coal that doesn't have much harmful material in it. And cars are much cleaner today. __5__.
A．But not all pollution in the air is caused by humans.
B．We students can also help make the air around us cleaner!
C．The job of cleaning up our air is difficult but not impossible.
D．Actually, natural ozone is in the upper part of our atmosphere.

【语篇解读】本文是一篇说明文。文中讲述了大气污染的危害、形成原因，以及应对它的一些方法。
答案与解析：
1．E此空设于段中，与上文存在逻辑上的指代关系。本句中的It指代的是第一句中提到的Air pollution。根据后一句的“It may also cause...”也可推出此句是要指出大气污染的一些危害。
2．A此空设于段中，是一个过渡句。本空前一句指出的都是由于人类的一些活动而导致的大气污染，而空格后面的“Forest fires and dust storms”都是自然灾害引起的大气污染，所以可推出此空承上启下，指出不是所有的大气污染都是人类引起的。
3．D此空设于段中，是对首句的进一步解释说明。首句提出，我们所知道的有两种臭氧，此句和后一句都是对这两种臭氧的进一步解释，即天然臭氧处于大气层的上部，而人类在地面上也会产生臭氧。
4．C此空设于段首，是本段的主题句。本段后面的内容都是围绕空气是可以被净化的这一说法而展开的。
5．F此空设于段尾，是对本段第三句的进一步具体解释。第三句提出，最近针对雾霾已经出现了很多措施，工厂用的煤含有很少的有害物质，汽车也变得更清洁了，甚至在雾霾天，一些城市都不允许汽车出行。
