As human populations grow, animal     1     often begin to     2    . The good news is that in many places around the world, areas are now     3     set aside just for animal use. These wildlife     4     allow animals to live in their natural or wild, habitats. Animals are also     5     in many zoos around the world.

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    .

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.

The carpet rose again and almost at once they were in a thick rainforest. A monkey watched them as it    1    .   “What are you doing?” asked Daisy. “I    2    myself from mosquitoes,” it replied. When I find a millipede insect, I rub it over my body. It contains a powerful drug which     3     mosquitoes. You should pay more attention to the rainforest and     4    how the animals live together. No rainforest, no animals, no drugs.”

In relief Daisy    1     into laughter. "Don't laugh," said the elephant, "We used to be an endangered    2    . Farmers hunted us without    3    ..."

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.
