常見錯誤
What are common mistakes with "Circulation"?Which "Circulation" sentences look correct but are wrong?
×The circulation of the blood is important for healthy.
✓The circulation of the blood is important for health.
After 'for', a noun is required. 'Healthy' is an adjective; 'health' is the correct noun form.
×This newspaper has a wide circulation of 100,000 copies.
✓This newspaper has a circulation of 100,000 copies.
The phrase 'wide circulation' is redundant when stating a specific number. 'Circulation' itself implies the number of copies distributed.
×We need to put the new policy into a circulation.
✓We need to put the new policy into circulation.
'Into circulation' is a fixed phrase meaning 'to start being used or distributed'. The article 'a' is not used here.
×The rumor was in circulations for weeks.
✓The rumor was in circulation for weeks.
'In circulation' is an uncountable noun phrase in this idiomatic usage. It should not be pluralized.
×Poor blood circulation can cause your hands and feet cold.
✓Poor blood circulation can cause your hands and feet to feel cold.
The verb 'cause' requires the structure 'cause + object + to + verb'. The original sentence is missing the infinitive 'to feel'.
×He has a problem with his blood circulation system.
✓He has a problem with his circulatory system.
The standard medical and biological term is 'circulatory system', not 'blood circulation system'. 'Circulatory' is the correct adjective form.
