Fill in each blank using the v-ing form of a verb from the box and state its function. One word will be used twice.

combine      cover      grow      take      limit       walk     experience

Xixi National Wetland Park, covering 10 square kilometres in western Hangzhou, is the first national wetland park in China. Combining city life, nature, and wetlands makes the park a popular destination both for tourists and local residents.

At Xixi, taking a boat tour, walking along paths, and experiencing local customs and traditions of the villages in this park are at the top of the list of people's favourite activities. With trees, bushes, and colourful flowers growing along the riversides,

the park shows different sides of beauty in different seasons.

In order to better develop as well as preserve this place, limiting human impact on Xixi Wetland was considered by the park designers. All the new buildings were designed in a traditional way to fit into the natural environment. This green,watery world is home to many birds and fishes. With trees    growing in the shallows,the wetland is a natural system for providing clean water and producing oxygen, which makes it the “green lungs of Hangzhou”.

Choose a place in your city or town as a destination for a school trip. Use the passage above as an example and write about your choice.
