One night,     1     winter, a bear came into the city in Vancouver Canada. It walked through the city streets past houses, shops and offices. Then it     2     (find) some food in bins outside a restaurant and started eating. In the morning, someone saw the bear and called the police. The police came with a vet (兽医) from the city zoo. They put the bear in a lorry and took it to the mountains outside the city.     3     (lucky), the bear was safe. But     4     happens in other countries when big animals come into cities? In Vancouver it is unusual     5     (see) a bear, but in some cities you can see big animals on the city streets every day.

Big animals usually come into cities to find food. In Cape Town in South Africa baboons (狒狒) come into the city when they are     6     (hunger). Human food is very bad for the baboons     7     (tooth) because it has a lot of sugar. Now, there are Baboon Monitors working in Cape Town.     8     (they) job is to find baboons in the city and return them to the countryside.

In Berlin in Germany, pigs sometimes come into the city for food. They eat flowers and plants in parks and gardens. Sometimes they eat vegetables from gardens     9     they walk in the street, causing accidents. Some people like the pigs and they give them food and water to drink. Other people do not like the pigs and they want the government and the police to stop them     10     (enter) the city.
