We find different kinds of animals in the world. Some animals, such as tigers and lions live in big forest and they are called  (1)  animals. Some others like sheep and dogs are  (2)  by men and they are called domestic(驯养) animals. These animals are very different from one another, but we can  (3)  them into big groups: those that eat other animals and those that eat grass and leaves. Animals like the  (4)  belong to the first group.

       Animals are  (5)  great uses to human beings. Men  (6)  wild animals for their fur and meat. Domestic animals are  (7)  more important to men. Without them, life will be  (8)  . People make use of animals in many  (9)  .

       Cows and dogs are useful to men’s  (10)  . They give 80% of the  (11)  men eat every year. Skin of some animals can be  (12)  into expensive overcoats and shoes, which are warm and comfortable and  (13)  a long time. They are very welcome in  (14)  countries. Wool, which is now one of the most important material for textile(纺织)  (15)  , comes from a special kind of  (16)  . From cows, we get milk. And we shouldn’t  (17)  that some domestic animals are kept for transport. Many people  (18)  ride horses. Arabs ride on camels which travel in deserts for days without  (19)  . In some places animals are still used to plough field.  (20)  is clear that men just can’t live without these animals.

In the north of Scotland there is a lake called Loch Ness. It is the biggest   (1)    in Britain. It is over thirty kilometers long and nearly 300 meters   (2)   It is cold and dark and not many people went there until after 1930. Then a road was made   (3)   the lake.

Holiday makers began to use the road, and this was when the  (4)  began. Someone said that he had seen a monster(妖怪) in the lake. He said it was twelve meters long. It had a long   (5)  and a small head. Then someone else said he heard  (6)  . Others said the same thing and in 1933 a London doctor took a   (7)  . It   (8)   like a monster with a long neck and a thick body but the photo was not too  (9)  . The newspaper printed the picture and   (10)   it the Loch Ness monster, or “Nessie”. Then the argument began.   (11)   people, however, were certain there was something living in the lake. Others said there was   (12)   there. In 1961, a lot of people joined together to make a real   (13)   to see and photograph the monster to find   (14)   there was one! Several times people thought they saw something but after ten years there was   (15)   no real proof（证据）.

Later underwater television cameras were used, but   (16)   found any real proof. However, they  (17)  find something interesting: a huge underwater cave. It was big enough to be   (18)   of a monster, but of course, this was not a proof. In 1975,however, some American scientists  (19)   a search group. They used an underwater camera. It took pictures every seventy seconds. Some of the pictures seemed to show a redbrown creature. Its body was about four meters long,  (20)  had a very ugly head on the end of a four-meter neck. Many people then began to believe in the monster. But even today we can’t be certain.

   The journey of water as it flows upon the earth can be a mirror of our own paths through life. Water begins its   (1)  on earth as it falls from the sky and streams down a mountain into a stream or river. In the same way, we come into the world and begin our lives on earth. Like a river that flows within the   (2)  of its banks, we are born with certain defining characteristics that   (3)  our identity. We are born in a specific time and place, within a specific family, and with certain gifts and   (4)  . With these limitations, we move through life,  (5)  many twists, turns, and barriers along the way just as a river  (6)  .
      Water is a great teacher that shows us   (7)   to move through the world with grace, bravery, determination, and  (8)  . When a river   (9)   at a waterfall, it gains energy and moves on, as we face our own waterfalls, we may fall hard   (10)  we always keep moving on. Water can inspire us not to become rigid (死板的)with fear or stick to what’s familiar. Water is  (11)   and does not waste time sticking to its past, but flows onward without   (12)   . At the same time, when there is a  (13)  to be filled, water does not run away from it in   (14)   of the dark; instead, water modestly and bravely fills the empty space. In the same way, we can face the   (15)   moments of our life rather than run away from them.
        (16)  , a river will empty into the sea. Water does not hold back from   (17)  in a larger body, nor does it fear a loss of  (18)   or control. It gracefully and modestly falls into the vastness by contributing its energy and joining without   (19)  . Each time we move beyond our individual characters to become part of something bigger, w e can try our best to   (20)   the lead of the river.

      Are forests always created by nature? A man from rural India proves that this is not necessarily   (1)  .

        Abdul Kareem, who used to be an airline ticketing agent，has a great love for the   (2)  ．Though he never went to college，he can talk about plants and trees like a(n)   (3)  ．In 1977，he bought a piece of   (4)   wasteland with the hope of growing trees on it．In the beginning，people thought he was   (5)   to waste his time and money on the land．But he  (6)   ignored them and kept working on the soil and planting trees there．The land was so  (7)  that it had to be watered several times a day．Kareem had to fetch the water from a   (8)   that was a kilometer away．In the first two years，none of the trees he planted   (9)  .However，in the  (10)  year，several young trees started growing．Greatly  (11)  by the result，Kareem planted more trees and his man made forest began to   (12)  ．

        Kareem let his forest grow   (13)  , without using fertilizers or insecticides．He believed in the   (14)   of nature to renew itself without the interference of humans. That’s   (15)   he did not allow fallen leaves or branches from the forest to be removed.

       After years of   (16)  , Kareem has not only realized his dream but also transformed a piece of   (17)  land into a beautiful forest. Today, his forest is  (18)  to 1,500 medicinal plants，2,000 varieties of trees，rare birds，animals，and insects. Now，  (19)   from all over the world come to visit his creation. They hope to do research on the secret of his   (20)   so that other parts of the world could benefit from it．

When people think of tigers, they think them strong and   (1)    . But now, the big animal is calling for our   (2)    .
There were once eight kinds of   (3)   in the world, but three    (4)   during the 20th century. In the last 70 years, the  (5)   of Siberian tigers (东北虎) has  (6)  from as many as 300 to less than 22 somewhere. The Siberian tiger has been   (7)   dying out completely.    (8)  the government doesn’t make any efforts, it’s quite   (9)  that there will be no more Siberian tigers in China in ten   (10)    twenty years.
In order to   (11)    the number of wild tigers in the  (12)   ten years, the World Wildlife Fund has started a   (13)    recently. It aims to save wild tigers and put an end to tiger   (14)   and killing. China, together with twelve other   (15)    , has joined in.
Wild animals,    (16)    red deer and wild pigs, are the main   (17)   of tigers. The hunting of these animals is the greatest threat (威胁) to tigers. So the most important thing is to   (18)    the animals that tigers    (19)   . To protect wild tigers, we need to call on   (20)    people to stop eating and hunting wild animals.
