Grammar and usage
To study the usage of the linking verb.
A linking verb is a word used to connect the subject of a sentence
to further information about the
state which the subject is in. The most common linking verb is ‘to
be (be/am/is/are/was/were/been)’.

linking verbs.

bed.

Internet becomes more of a problem every day.
4. Linking verbs are most often
followed by an adjective. Sometimes,
they can be followed by a noun or a prepositional phrase.

18 March
Today I feel worn out. This morning, I took part in a debate about the Internet. The Internet is very controversial. It seems very popular with many people, but there are still some people who do not like it at all. They say that it is full of information that cannot be trusted, and that it stops people from spending time with their families and friends.
I admire the boy I debated against because he was very skilful. He made some quite reasonable points and gave a good speech. I talked to him after the debate. He seemed tired too. He doesn’t really think the Internet is bad, but he thinks we should pay attention to the problems it can cause. I agreed and told him I felt sure that if we use it in an intelligent manner, the Internet can be a good tool.
We were both happy with the
outcome of the debate. People stayed silent and listened to us, and applauded at the end. Mum predicts that I will become quite a good public speaker if I continue to take part in debates. I am hopeful that I will , and I am eager to debate again because today proved very successful!
