Search and rescue dogs
Introduction
Dogs have been very helpful in rescue efforts[(为达到某一目的的)有组织的行动，一系列活动] on land. Due to the effort of well-trained search and rescue dogs, thousands of human lives are saved every year.
History
The Great St Bernard Hospice [snt b n d h sp s](大圣伯纳救护所) , which was built in 1049 for travellers in Switzerland [ sw ts l nd], raised a type of dog known as the St Bernard. This type of dog has been used in mountain rescues for hundreds of years.
Advantages and disadvantages
Because of their small size and sharp sense of smell, dogs can locate survivors much faster than humans can. However, it takes much time and effort to train them. Also, dogs may lose their sensing ability if they work too long. In that case, they have to retire.
A rescue story
When a destructive earthquake hit Nepal [n p l] in 2015, six well-trained search and rescue dogs worked alongside members of the China International Search and Rescue Team. They went to the location and two minutes later gave the rescuers a strong signal. At last, a 16-year-old boy was rescued.
4. Sort out(理顺；整理)information about your chosen topic and put it together in a logical way.
As a group, put together your information to make your part of the information folder. Use the example above to help you. Present your part to the rest of the class. Then as a class, put all the parts together to make the information folder.
5. Proofread(校阅；校对；勘校) the writing to make sure there are no language mistakes.
6. Present your group work to the rest of the class and ask other groups to ask questions about it or put forward suggestions.
C. Evaluation
1. Evaluate other groups’ works in class.
2. Improve the content and structure of your works and then make a complete information folder.
Assessment
A. In pairs, rank your performance level in the following areas from 1 to 5. Write down your own assessment in the column “Me” and ask your partner to write down his/her assessment of your performance in the column “Partner”.
B. If improvement is required for some of the areas above, make an action plan.
