Passive Voice

Passive voice

• The passive voice is less usual than the active voice. The active voice is the "normal" voice. But sometimes we need the passive voice.

• The structure of the passive voice is very simple.

• The main verb is always in its past participle form.

THE STRUCTURE OF THE PASSIVE VOICE

Use of the Passive Voice

• We use the passive when:

1. We want to make the active object more important.

2. We do not know the active subject.

Example:

1.Hay fever is caused by breathing in pollen

particles and by pollen getting into the eyes.

2.Hay fever is happened in early spring.

Hay fever, also called seasonal allergic rhino-conjunctivitis, occurs in the spring and summer, and affects the eyes and nose. It is also linked to oral allergy syndrome.

TextHay Fever

• Causes of hay fever Hay fever is caused by breathing in pollen

particles and by pollen getting into the eyes. You can get hay fever at any time from early spring to late summer, depending on which pollen or pollens you're allergic to.

The pollens most likely to cause problems in early spring are those from trees such as the silver birch, ash, oak and London plane. Grasses pollinate during mid-summer from May to August. The most profusely pollinating grasses are timothy, rye, cocksfoot, meadow and fescue.

The main Symptoms of hay fever• Repeated sneezing attacks• Runny or itchy nose• Itchy or watery eyes• Itchy throat, palate and ears• Loss of concentration• General feeling of being unwell (hence 'fever')

• Preventing hay fever• If you have hay fever, there are steps you can take

to avoid exposing yourself to pollen:• Keep an eye on the pollen count (often included

in weather reports) and stay inside as much as possible when it's high.

• Wear wrap-around sunglasses to stop pollen getting in your eyes

• Saline douches or a little Vaseline applied inside the nose will reduce symptoms

• Keep car windows closed and switch on the air conditioning to prevent pollen entering the car

• Keep bedroom doors and windows closed in mid-morning and early evening when pollen levels peak

• Avoid areas such as parks or fields, particularly in the early evening when there's a lot of pollen floating at nose level

• Get someone else to mow the lawn and don't lie on freshly cut grass

• Change into clean clothes when you come home and wash the clothes you wore outside

Activity 2: Fantasize

• Direction: Think and discuss in your group about “If you were an imaginative doctor, what would you do to prevention hay fever?”

Example:

• Student A: I will produce an inhalant. When the patient smell just only once time, they will be back to good health.

• Student B: I will create an air scanner. It uses to scan the air; if the air has a germ of Hay fever, the scanner will tell you by voice.
