When I was a freshman I joined Volunteers for Wildlife, a rescue and education     1     (社团) at my college. Trying to help injured or sick creatures can be heartbreaking, for     2     (存活) is never certain. However, when it works, it surely b    3     the creatures and us.

I got a rescue call from a woman in Mutton town. She had found a young owl on the ground by a    4    . When I arrived, I saw a 2-to-3-week-old owl. I soon examined the chick and it seemed fine with only     5     (不严重的) injury on its wing. My next work was to construct a nest and anchor it in a tree. A basket was found. I put some pine branches m    6     with grass into the basket to make this nest comfortable. I placed the chick in the nest, and it quickly calmed down.

Now what the chick needed was     7     (情感的) company. I gave the homeowner a recording of the hunger screams of owl chicks. It was i    8     to attract the chick’s parents and encourage our chick to start calling as well.

Much to my r    9    , the homeowner called next day, saying that the parents had responded to the recordings. I drove over and what i    10     me most was an active chick accompanied by its lunch in the nest. The parents had done their duty and would probably continue to do so.

When you think of a fearsome hunter, images of lions and sharks may     1     to mind. Recent research by     2     scientists, however, shows that in fact, humans are the most fearsome hunters who have the greatest     3     on animal populations. Human activities have brought many animals close to     4    . In the last 500 years, over 300 species of animals have gone extinct. Some activities, such as hunting and fishing, directly harm animal,     5     other activities, such as development in towns and cities, impact indirectly on animal populations.

Human activities that have indirect     6     on animals can be just as harmful. When we build farms or factories, we destroy animal habitats and leave many animals with     7     to live, or no food to eat. We can also     8     animals in danger without ever entering their habitats. Air, water, noise and light pollution can all have a deep and     9     influence quite far from their source. Partly due to pollution caused by ship traffic and other human activities, the dolphin population has dropped greatly. As the human population continues to grow,     10     does the effect we have on animals.

To fully realize your     1     , it is important for you to make the most of our school resources. Take     2     of your classes, learn from your teachers and classmates, and make use of our school facilities. There are also a lot of school activities for you. Join in a club or two, and take an     3     part in different sports.

Of     4     importance are good study habits, useful skills and a positive     5    . Carefully plan your study, set clear     6     and     7     your schoolwork with other activities. As a senior high school student, you must make     8     to improve your communication and problem-solving skills. Last but not least, always look on the     9     side and never lose hope, even in difficult situations. In time you will find yourself growing into a well-rounded     10    .

Human activities that have i    1     effects on animals can be just as harmful. When we build farms or factories, we destroy animal habitats and leave many animals with n    2     to live, or no food to eat. We can also put animals in d    3     without entering their habitats. Air, water, noise and light pollution can all have a deep and damaging influence quite f    4     from their source. Partly due to pollution caused by ship traffic and other human activities, the dolphin population has d    5     greatly. As the human population continues to grow, so does the effect we have on animals.

I can’t wait to describe to you what senior high school life is like. The p    1     before you leads to a world full of challenges: a new environment, new knowledge and new ways of thinking. However, for those of you with a p    2     mind, opportunity lies in each challenge. When you rise to the challenges, you will have the opportunity to a    3     great knowledge and enjoy personal growth. Most importantly, your time and e    4     at senior high school will open the door to your p    5    .

Hunting and fishing have had damaging effects on the world’s animal populations. Some people hunt animals for f    1    : whale meat is eaten in some parts of the world. Some people hunt animals for f    2    : animal skin is used to make coats and bags. Still others hunt animals just for fun: deer are tracked and shot by people who enjoy the e    3    of the sport.

Human activities that have indirect effects on animals can be just as h    4    . When we build farms or factories, we destroy animal habitats and leave many animals with n    5    to live, or no food to eat. We can also put animals in danger without ever entering their h    6    . Air, water, noise and light pollution can all have a deep and damaging i    7    quite far from their source. Partly due to pollution c    8    by ship traffic and other human activities, for example, the dolphin population has d    9    greatly. As the human population continues to grow, so does the e    10    we have on animals.
