Task 1 Study the two paragraphs below.Both paragraphs discuss the same topic.In your opinion, which paragraph has unity and which one doesn't?Explain how individual sentences break the unity either by introducing a new idea or by being"off the topic". Surviving Cancer Progress is gradually being made in the fight against cancer.In the early 1900s,few cancer patients had any hope of long-term survival.In the 1930s, less than one in five cancer victims lived more than five year.In the 1950s, the ratio was one in four.Currently,the ratio is down to one in three.The gain from one in four to one in three represents about 58,000 lives saved each year. Surviving Cancer Progress is gradually being made in the fight against cancer.In the early 1900s,few cancer patients had any hope of long-term survival.But because of advances in medical technology,progress has been made so that currently one in three cancer patients survives.It has been proven that smoking is a direct cause of lung cancer.However,the battle has not yet been won.Although cures for some forms of cancer have been discovered, other forms of cancer are still increasing.Heart disease is also increasing.Task 1 Study the two paragraphs below.
