Suddenly, the aftershock struck, which made the rescue work more difficult. “A nurse in the ward was covered with rubble,” a doctor screamed with horror then. We volunteers rushed to     1     (帮助医生抢救被掩埋在废墟里的护士). Although we were faced with falling rubble from time to time, we focused our efforts on removing the bricks and the rubble that trapped her.     2     (通过我们的共同努力), the nurse was rescued.

The metal pipes and taps cracked and the ground was covered with bricks. There was neither     3     (电，填单词) nor water. Many people     4     (使落入险境，填单词) at home suffered a great deal. Fortunately, , the government immediately directed the     5     (拯救人员，填词组) to evacuate the people in danger and put up s    6     (a structure built to give protection) in the open air. Ambulances arrived to provide first aid. In the meantime, the s    7     (the things such as food, medicines, fuel, etc. that are needed by a group of people)provided to the earthquake-stricken area were collected from all around the city.     8     (经过不懈努力，填词组), the whole city began to breathe again and witness a dramatic revival.

Strange things were happening in the countryside of northeastern Hebei. For several days, the water in the village wells rose and fell, rose and fell. There were deep c    1     that appeared in the well walls. At least one well had some s    2     gas coming out of it. Chickens and even pigs were too n    3     to eat, and dogs refused to go inside buildings. M    4     ran out of the fields looking for places to hide, and fish jumped out of the water. At about 3:00 a.m., on 28 July 1976, bright lights were seen in the sky outside the city of Tangshan and loud noises were heard. But the city’s one million people were a    5     as usual that night.

At 3:42 a.m., everything began to shake. It seemed as if the world were coming to an e    6    ! Eleven kilometres directly below the city, one of the most deadly e    7     of the 20^th century had begun, a quake that even caused d    8     more than 150 kilometres away in Beijing. Nearly one third of the whole nation felt it! A huge crack, eight kilometres long and 30 metres wide, cut across houses, roads, and waterways. Hard hills of rock became rivers of dirt.

Wildlife     1     (开始存在) billions of years ago, which used to live happily in their own homes and live     2     (与……和谐相处) other animals and plants. However, in recent years, animals are     3     (灭绝) at an alarming rate, 75 species every day     4     (平均). In order to obtain their parts, organs, or the skin and fur, or to obtain high     5     (利润), human beings ignore animal protection laws, engaging in     6     (违法的) killing. Furthermore, human activities have direct or indirect     7     (消极影响) animals.     8     (一方面), the expansion of human activity space means the decrease of animal habitat, which directly disturbs their peaceful life.     9     (另一方面), human activities lead to the rise of global temperature, which threatens the survival of some animals, especially those species living in the polar regions.

Protecting animals is to protect ourselves, which is urgent. If we do not act     15     (立刻;马上), perhaps the next species to die out in the near future will be ourselves.
