Having a cheetah as a pet in the house? Does it sound scary to you? But for a family in South Africa, one cheetah is treated as a VIP (Very Important Person) in the house.
The big cheetah is named Jolie, after the film star Angelina Jolie. 1. She can often be found eating from the kitchen table, taking a short sleep on the sofa, or even sleeping on Lucy and Jeff’s bed. The big cat also sleeps and plays with the Browns’ other pet, the more usual one — a sheepdog (牧羊犬). 2.
Having a cheetah as a pet is unusual. At first, Mrs Brown wasn’t willing to keep a cheetah as a pet. She said, “ 3. But we are now happy that we did it — she is part of the family.”
Just like her name, four-year-old Jolie has achieved a celebrity status (名人地位) in the Browns’ hometown. Fans often come to their home to take pictures of her. 4.
However, a cheetah is always a cheetah. 5. “She makes a lot of mess in the house, urinating (小便) everywhere and chewing everything. It’s her wild instincts (本能),” said Mrs Brown.
There might be some problems of having a cheetah as a pet in the house, but some unusual fun must also be waiting ahead.
It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to sneeze and later you may cough. You must have a cold! Wait a moment. Could it just be a common cold or the flu (流感) that’s been going around?
A cold gives you a runny nose and cough. But it’s usually easy to deal with. Some take medicine while others drink herbal tea or chicken soup. Usually you feel better after a week.
On the other hand, the flu can be much more dangerous. It usually gives you fever. Sometimes it can cause death. According to an American magazine, the worst flu killed about 50 million people from 1918 to 1919.
Don’t worry. If you get a flu vaccine (疫苗), it can stop you from getting the virus (病毒). Flu vaccines work by giving the body a small amount of flu viruses. This causes your body to develop antibodies (抗体). So next time you get the flu, the antibodies should help you.
The flu virus changes every few years. Therefore, there are so many types of flu, such as H1N1 and H5N1. The antibodies for one type of flu can’t help us against all types of flu. That’s why we need to get the vaccine every year.
However, good health habits may also help stop you developing a cold or flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help you strengthen your immune system (增强免疫系统).

What will the car be like in the future? Maybe we can sit in a car that can drive itself.
About 40 years ago, scientists from the United States started to develop self-driving cars (无人驾驶汽车). The most famous recent one was made by Google in 2009. There are cameras and radars (雷达) on the top of the car. They allow the computer in the car to draw a 3D map of the environment. Chinese scientists have also successfully developed a self-driving car. The car made a trip from Changsha to Wuhan.
Is a self-driving car safe? A recent study shows that robots make safer drivers than humans. If only 10% of cars on the street are self-driving, they will save 1,000 lives (生命) every year. If 90% of vehicles (交通工具) are self-driving, 21,700 lives will be saved a year. However, a self-driving car is expensive and each costs about $100,000. So it is impossible to be very popular in the near future.
