It got lost five years ago. Jennifer looked for it everywhere but failed each time. She thought Scrub would never e back. But one day she got a call from an animal shelter（庇護(hù)所） and was told they had found Scrub! How did they know Scrub belonged to Jennifer? How did they know Jennifer39。s phone number? All the information was available because of the microchip, a very small puter chip（薄片）. It was placed under Scrub39。s skin many years earlier. The microchip is usually placed under the skin of an animal39。s shoulder to keep its ID number. Once the chip is in place, the pet does not feel it anymore. When lost pets are brought to animal shelters, people there use a special tool to look for the microchip and read the ID number on it, then they39。ll call the microchip pany to match the number to the information of the pet39。s owner. This is how the shelter was able to tell Jennifer that they had found Scrub. Microchips have helped thousands of owners get their lost pets back. In New York, a dog named Roxy was missing for months. Then a woman found her on a busy street in New Jersey. No one knows how the dog got to a different state. However, thanks to her microchip, Roxy was soon returned to her grateful owner. In 2008, a couple got their cat George back after he had disappeared 13 years earlier! When George got lost, the couple tried everything to find him. They visited animal shelters every day for six months, made posters and even offered a $500 reward（酬金）. As years went by, they thought George would never be back till they got the call from an animal shelter. Without the microchip, the cat would never be able to e home again. Microchips can not only work for a pet39。s whole life but help lost pets no matter how far they39。ve been away from home. This is why microchips may be just the thing to help bring missing pets back home.（1）How did Jennifer find her pet cat?

While most people get over it, for others it doesn39。t go away easily. The WHO says that about 20 percent of teenagers worldwide suffer from mental illness. It39。s thought that the number of teenagers with mental illness around the world will increase by half by 2020. It will bee one of the main causes of illness, and even death. In China, the picture isn39。t bright, either. About one tenth of teenagers under the age of 17 have a mental health challenge. The world is changing fast. Study and relationships have always caused stress, but today the stress is much higher than before, the WHO said. A research centre in Oxford University says that young people today have big stresses at school. For example, they experience bullying （欺凌）. In a 2017 report, the centre noted that the Internet was a special source （渠道） of stress. Online, young people often see messages about perfection and this causes the young great uncertainty about their futures, says the centre. Also, according to China Daily, Chinese people don39。t ask for help with their mental problems. They fear that others will think less of them if they say that they are in mental trouble. Elaine Peng, a US mental health educator, makes a similar point. And in the UK, over three quarters of young people believe their mental problems have a social stigma. It is reported in 2017 that a quarter of young UK people wouldn39。t ask for help if they developed a mental problem. Young people who don39。t ask for help for their condition may be creating problems for themselves in the future. Elaine Peng warned that, If we hide our mental health, it may remain a problem forever. My message for young people is, if you feel something is wrong within you—ask for help, he told China Daily. （1）Which of the following is NOT the cause of stress accor
