6.Underline the use of the -ing form in the following passage, marking the passive -ing form specially.(Ex 3 P23)

Fishing nets in the sea have become a serious problem. They may be many kilometres long with plastic balls to keep them floating on the water, and weights to hold them down on the seabed. Unfortunately, the plastic nets are impossible to see underwater. So the term to describe them is "a wall of death". Their advantage is that they catch fish efficiently. However, they also cause danger to sea animals. First, not only target fish are caught in the net, but many other sea animals are found hanging there. Those not needed for marketing are thrown away. Second, nets are in danger of being cut loose by fishermen. If a net becomes free-floating, it is moved by the tides all over the ocean. It behaves as a hidden danger, killing all that are trapped in it. So many animals being caught in driftnets make many think that it is necessary to have a worldwide ban on all driftnet fishing.
