(D)I often heard or read about natural disasters-the eruption(爆发)of Mount St. Helens; a volcano(火山)in the state of Washington; Hurricane(飓风)Andrew in Florida; the floods in the American Midwest; terrible earthquakes all over the world; huge firs; and so on. But I’ll never forget my first personal experience with the strangeness of nature-the “London Killer fog” of 1952.It began on Thursday, December 4, when a warm air covered southern England. With the freezing–cold air below, a heavy fog formed. Pollution from factories, cars, and coal stoves mixed with the fog. The humidity was terribly high, and there was no breeze(微风)at all. Traffic stopped. People couldn’t see, and some walked onto the railroad tracks or into the river. It was hard to breathe, and many people got sick.

　　 Finally on Tuesday, December 9, the winds came and the fog went away. But after that, even more people got sick. Many of them died.

(C)If you are lucky enough, you may find the hummingbird(蜂鸟), the smallest bird of the animal world, in a south American forest.

Though the hummingbird is no bigger than a bee and weighs only 2 to 3 grams, it can fly as fast as 50 metres in a second. It can fly forwards as most birds do, and it can fly backwards as well. The strangest thing about it, however, is that it can stay still in the air, just like a helicopter(直升飞机).

Whenever a hummingbird needs food, it will fly slowly towards a flower. It won’t stand on the flower, as bees would, but just hangs to the flower and then begins to sunk(吸吮) the honey from inside the flower.

The hummingbird is very particular in building its nest(巢). It takes great trouble to choose material, preferring soft ones to hard ones. Its eggs are so small that a common match box can hold as many as one hundred of them..
