Learning a new language isn’t easy. For many of us, speaking the language is even harder! Here are some tips(建议)to help you become more comfortable speaking English.

Tip 1  When you study, make your mouth do what your mind is learning. If you read aloud, you make your mouth and your mind work. This will help you with both speech and pronunciation.

Tip 2 Talk to yourself as much as possible. You need to be comfortable making sounds in English. All over the day, talk to yourself in English! This will help you feel comfortable thinking in English. Then write down what you are saying and read it aloud.

Tip 3  Have a “study partner”.Get together with him or her at least once a week and study together. Speak as much English as you can whenever you meet. Then you can help each other.

Helping yourself talk in English

There are about 80,000,000 mines*  under the ground in more . than 60 countries. It is difficult and dangerous to clear these rnines, About 50  people including many children were’ killed ‘or htirt each iay.  In 2003,  APOPO,  a Dutch research com pan y that uains the an imals, came up with the-idea of s\ng 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 l.35 kg, 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 no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed 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 scratched the ground to tell the deminers*  that they smelt out’a mine.  Then the mine was cleared. It had  taken two ‘deminers  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 deminers 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 Weeqens, the head of the APOPO.
