low," said the researcher. (Attribute)
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.
Step 3 Application
1.Complete each of the following sentences in several ways using the passive -ing
form. Then compare in pairs. (Ex 4 P23)
2.Try to connect the sentences into a short passage.
