We can also     1     animals in danger without ever entering their habitats.Air ,water,noise and light pollution can all have a deep and damaging     2    .Partly due to pollution     3     by ship traffic and other human activities,the dolphin population has     4     greatly .As the human population continues to grow,     5     does the effect we have on animals

But hope was not lost. Soon after the quakes, the army sent 150,000 soldiers to Tangshan to dig out those who were     1     and to     2     the dead. More than 10, 000 doctors and nurses came to provide medical care. Workers built     3    for survivors     4     homes had been destroyed. Hundreds of thousands of people were helped. Water and food were brought into the city by train, truck, and plane. Slowly, the city began to     5    again.

Tangshan started to     6     itself and get back up on its feet. With strong support from the government and the tireless     7     of the city’s people, a new Tangshan was built upon the earthquake ruins. The new city has become a     8     to more than seven million people, with great improvements in transportation, industry, and environment. Tangshan city has proved to China and the rest of the world that in times of disaster, people must     9     and show the     10     to stay positive and rebuild for a brighter future.

The Earth is made up of three layers. In the centre is the core, which is as big as the Mars and has a high     1     of over 7,000˚C.     2     the core is a thick layer called the mantle,     3     lower part is solid rock,     4     portion is molten rock called the magma. Floating on top of the magma is the Earth’s rocky crust.

The crust is made up of tectonic plates. These huge plates are moved slowly by magma currents below, sliding past each other with     5    . If a plate is forced down     6     another and gets     7    , pressure will build up until the stressed rocks suddenly     8     apart, causing     9     ground movements called earthquakes. The point where the rocks suddenly jolt or break is called the epicentre, from which, powerful shock waves     10     out in all directions.

Daisy smiled. “That’s good news. It shows the     1     (important) of wildlife protection, but I’d like to help as the WWF suggests.” The carpet rose again and almost at once they were in a thick rainforest. A monkey watched them as it     2     (rub) itself. “What are you doing?” asked Daisy. “I’m protecting myself     3     mosquitoes,” it replied. “When I find a millipede insect, I rub it over my body. It     4     (contain) a powerful drug     5     affects mosquitoes.”

But    1    . Soon after the quakes the army sent 150,000 soldiers to Tangshan to    2    and to bury the dead. More than 10,000 doctors and nurses came to    3    . Workers built shelters for survivors    4    . Hundreds of thousands of people were helped. Water and food were brought into the city by train, truck, and plane. Slowly    5    again.

Tangshan started to    6    . With strong support from the government and the    7    of the city's people. a new Tangshan was built upon the earthquake ruins. The new city has become    8    more than seven million people, with great improvements in transportation, industry, and environment. Tangshan city has proved to China and the rest of the world that    9    , people must unify and show the wisdom to     10    .

I have the greatest job in the world. I study     1     (volcano) and I travel to     2     (usual) places and meet interesting people from all over the world. I am never bored. I find that the volcano eruption     3     (it) is really exciting     4     (watch) and I should never forget my first sight of one. It was in the second week after I arrived in Hawaii.     5     (work) hard all day, I went to bed early. I was fast asleep when suddenly my bedroom began shaking and I heard a strange sound, like a railway train passing my window. Having experienced quite a few earthquakes in Hawaii already, I didn’t take much notice. I was about to go back to sleep     6     suddenly my bed room became as bright as day. I ran out of the house into the back garden     7     I could see Mountain Kilauea     8     the distance. There had been an eruption from the side of the mountain and red hot lava was     9     (fountain) hundreds of meters into the air. It was     10     absolutely fantastic sight.

A terrible earthquake hit the city of Tangshan on July 28,1976. Thousands of people died and many children     1    (leave)without parents. Many houses fell down and sand filled the wells     2     of water. People were     3     (extreme) shocked. Water, food and electricity were hard     4    (get)in the city and people began to wonder how long the disaster would last. The whole city was     5    (在废墟中) and the world seemed at its end.

The people of Tangshan didn’t lose hope, because 150,000 soldiers were sent to help the rescue workers.     6     soldiers tried their best to dig out those     7     were trapped. They also built     8    (避难所) for the survivors. Slowly, the city began to come back to life.

Nowadays, with the rapid development of our society, the environment we live in is severely damaged. The u    1    (普遍) acknowledged belief that the development of economy is a top priority is being challenged. People are increasingly     2    (意识) of the significance of protecting the environment in that nothing can     3     (弥补) for the damaged environment.

Making a    4     for the fact that environmental pollution is becoming more and more serious, we’d better take immediate measures to solve it. On the one hand, we are supposed to make some a    5     to the way in which our economy is developed. On the other hand, in order to solve this t    6     problem,     7     (合作) is also necessary. Only when the enterprises and the governments make a joint effort will we be able to make progress.

Actually, we have no o    8     but to develop our economy in an environmentally-friendly way. I firmly believe that as long as we don’t s    9     from the responsibility everyone of us should take, developing without polluting the environment is no longer     10     (理论上) possible.
