**Completed passage:** Dengue fever is **a** tropical virus-infected disease. It is **prevailing** in more than 110 countries. It is **caused** by dengue virus. The fever is spread by **female** Aedes mosquitoes. When the mosquito **bites** a man, the virus enters the blood cell, grows rapidly and attacks many **organs** of the body. There is **no** specific medicine to treat dengue infection. So, we must put emphasis **on** preventive measures. For this we must keep our surroundings clean to stop **breeding** of Aedes mosquitoes. Again we must not **allow** to accumulate water in any open space for more than two days.

**Notes:** (a) needs the article 'a' before a consonant sound ('tropical'). (c) is passive voice, so 'cause' becomes 'caused'. (e) takes the present simple form 'bites' after the singular subject 'the mosquito'. (i) follows the preposition 'stop ... of', so the verb 'breed' becomes the gerund 'breeding'. The word 'on' is used twice in the box idea, once as a preposition after 'emphasis'.
