12 March
Today I feel worn out. This morning, I took part in a debate about medicine and exercise. Medicine plays an important role in our lives, but there are still some people who do not like it. They say that most drugs have side effects, and that notall diseases can be cured by medicine.
Taking exercise, on the other hand, is
always safe.
The boy I debated against was very skillful.
He made some quite reasonable points and
gave a superb speech. I talked to him after
the debate. He seemed tired too. In fact,
He doesn’t really think medicine is bad, but he believes we should be aware of the problems it can cause. I told him that if we are cautious about using medicine, we can benefit from it. 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 eager to debate again because today proved very successful!Part B Choose a proper linking verb to fill in each blank.
