There are not many people around who say they like rats(老鼠). When you see one of them, you may want to run in the opposite direction.

There is one man though who has always enjoyed staying with rats, even when he was a young boy. His name is Bart Weetjens and he comes from Belgium in Europe. As he grew up, he learned everything about rats. He knew that they have a very strong sense of smell. He realized that it might be possible to train rats to help solve a problem that troubled some Southeast Asian countries.

Clearing away unexploded bombs and landmines(未爆炸的炸弹和地雷) is a difficult job. Bart began to train rats to look for explosives. Because a rat’s sense of smell is so strong, they are able to smell a thing known as TNT that is used in bombs. And because rats are not heavy, if they place their weight on an unexploded bomb, they will not cause it to explode(爆炸).

Bart chose African Giant Pouched Rats for the job. They are well known for being calm and smart. Training begins when they are about six weeks old, and it lasts for nine months. Once trained, one rat can search up to 200m in 20 minutes. The same area would take a human up to four days. Trained rats are known as Mine Detection Rats, or MDRs, and they have worked successfully in Cambodia since 2015.

1.When Bart Weetjens was a young boy, he enjoyed ____________.

2.As Bart Weetjens grew up, he learned that rats have a very ____________.

3.Rats will not cause an unexploded bomb to explode because they are ____________.

4.It takes ____________ to train African Giant Pouched Rats.

5.MDRs have ____________ since 2015.

Children know that summer is probably the most fun of all seasons. However, experts say it is also the most dangerous, especially for children aged 14 and under. In its first study of children's safety in the US, the National Safe Kids Campaign (NSKC) found nearly half of the injury-related (与伤害相关的)deaths among children happened in summer.

Experts are not surprised by the study's results. They always know summer is a dangerous season for children. During the summer, children are out of school and spend more time outdoors. They are more likely to get into an accident or be injured. "While we encourage children to be active and spend more time outdoors, they need to understand the importance of safety." said Everett Koop, an expert of the NSKC.

To help children stay safe, the NSKC started a "Make it a Safe Kids Summer" campaign during National Safe Kids Week, from 5th May through 12th May, Here are some important summer safety tips from the NSKC.

●Always wear your seat belt when in a car.

●Make sure there is an adult around when you decide to go swimming.

●Wear a lifejacket when on a boat or doing water sports.

●Obey all traffic rules.

●Don't meet e-pals alone.
