Jane Goodall was born in London in 1934. She became interested in animal stories when she was a very young child. She always dreamed of working with wild     1     (animal).   When she was eleven years old, she decided that she wanted     2     (go) to Africa to live with and write about animals. But this was not the kind of thing young women usually did in the 1940s. Everybody was laughing except her mother. “If you     3     (real) want something, you work hard, you take advantage of the opportunity, you never give up,and you will find a way,” her mother said to her. The opportunity     4     (come) at last. A school friend invited her to Africa. Jane worked as     5     waitress until she got enough money to travel there.

In 1957, Jane Goodall traveled to Africa. She soon met the well-known scientist Louis Leakey and began working for him as an assistant. He later asked her to study a group of chimpanzees     6     (live) by a lake in Tanzania. Very little was known about wild chimpanzees at that time.

Jane spent many years studying chimpanzees     7     this area of Africa. It was no easy work. They were very shy     8     would run away when she came near. She learned to watch them from far away using binoculars (双筒望远镜). Over time, she slowly gained     9     (they) trust. Watching the chimpanzees, she made many discoveries. They ate vegetables and fruit. But she found that they also ate meat. A few weeks later, she made an even more     10     (surprise) discovery. She saw chimpanzees making and using tools to help them catch insects.

A new report released on Tuesday by Pethadoop said cats accounted for 59.5% of all the pets among the 30,000 respondents surveyed for the research. As of last year, there were some 58 million pet cats in China's urban households,     1     (compare) with some 54 million pet dogs.

China     2     (see) an increase in pet ownership in recent years, with people     3     (increasing) choosing cats. Globally, though dogs are still more common pets, cats have emerged     4     the most popular pet in the European Union lately.

Cats have also turned into a social phenomenon in China and elsewhere, with the cats becoming the subject of popular videos. Many cat lovers online also identify     5     (they) as “cat slaves”, publicly declaring their pet preference.

Researchers owe the fast growth of cat pets to the lifestyle in Chinese cities, with some experts also suggesting that the cat's     6     (popular) with the young is     7     (relevance) to the young generation's pursuit of individuality.

Liu Yi, the report’s chief editor, said that many people living in the cities have busy lives     8     they live in relatively smaller accommodations, thus     9     (make) cats their ideal companions—it's easy to raise cats, unlike dogs that require more attention and outdoor activities.

“Our research shows that     10     number of the pet owners born after 1990 and 1995 takes up large portion,” he said. “Young people are looking for freedom in their lives, and the habits of cats are more suited to their needs.”
