There are about 80,000,000 mines (地雷) under the ground in more than 60 countries. It is difficult and dangerous to clear these mines. About 50 people including many children were killed or hurt each day. In 2003, APOPO, a Dutch research company that trains the animals, came up with the idea of using rats to search for the mines.

The animal trainers found that a kind of rats from Africa were clever and had a sharp sense of smell. The rats were about 75 cm long and weighed about 1.35kg, light enough to run across a minefield without setting off the mines.

In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were not afraid of people and the things around them anymore. Then they were trained to connect a click sound with food. After the rats had learned that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana. The method was called clicker training. "The training isn't easy," said trainer Abdullah Mchomvu. "You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals".

After nine months' training, the rats were taken to a minefield. They ran across the minefield, stopped, sat and searched the ground to tell the domineers (排雷员) that they smelt out a mine. Then the mine was cleared. It had taken two domineers a day to clear a 200 ㎡ minefield, but with the help of two rats they could finish it in two hours.

The rats and the domineers saved thousands of lives, "The rats did this job much better than we expected. So far they have helped to make almost 2,000,000 ㎡of land safe. "They are heroes". Said Bart Weetjens, the head of the APOPO.

Most people hope to have a memory which helps them succeed in study, work and life. Can memory be improved? Luckily, hundreds of studies in the past 50 years have already given us a clear answer.

A healthy lifestyle keeps your brain young and memory sharp. First of all, it is necessary to have a healthy diet. Eating more food rich in B vitamins and Vitamin E, such as vegetables and lean meat, helps you have a better memory. Second, doing exercise can keep your brain alive, too. Proper exercise provides much needed oxygen for the brain. Running, riding a bike, swimming and even walking two or three times a week are helpful. Third, getting enough sleep is important. Only when your brain gets a good rest, can it work well. The healthier your lifestyle is, the better your memory will become, but do not expect a sudden change—it takes a long time to make a difference.

Memory skills help you remember things better. The following three are the most widely used. Chunking is a way of remembering a piece of information by cutting it into smaller ones. For example, to memorize a ten—digit telephone number 2127983630, you can divide the digits into three groups: first 212, then 798, and lastly 3630.This method is much more effective. Organization means organizing information into groups of the same kind. For example, trees, grass and flowers are plants; tigers, pandas, horses and cows are animals. Imagery is remembering newly learnt information by using your imagination and connecting it with something that you are familiar with.

However, memory skills will hardly work if you don't understand the information. What's more, only a regular (有规律的) review can make the memory last long. That is why students are always advised to go over what they have learnt after one day and then after three days, and then use it as regularly as possible.

Human brains are like muscles that need nutrients and exercise to become stronger. If you make a few lifestyle changes and try some memory skills, you can certainly improve your memory.

1.How many ways of keeping a healthy lifestyle are mentioned in the passage?

A.Two B.Three C.Four D.Five

2.Which of the following examples is the use of the skill "organization"?

A.Remembering the word "yellow" by putting it into the group of "color".

B.Remembering the meaning of the word "red" by connecting it with fire.

C.Remembering a long and difficult passage by understanding its meaning.

D.Remembering the post number 0708591 by diving it into 070 and 8571

3.According to the passage, why should students go over what they have learnt?

A.To use it better every day B.To understand it in a better way

C.To improve memory skills D.To remember it for a longer time

4.Which of the following maybe the best title of the passage?

A.Does Good Memory Help You Succeed.

B.A Healthy Lifestyle, A good Memory.

C.Memory Needs Skillful Training.

D.A Healthy Lifestyle with Memory Skills, You Get a good memory.
