ZERO CONDITIONALS SENTENCES (EXPLAINED IN HINDI)

Zero conditional sentences में sentence के दोनों ही parts Present Simple Tense में होते हैं. ये conditionals sentence तब use किये जाते हैं जब किसी बात का परिणाम निश्चित होता है; और किसी सामान्य सच्च तथ्यों (general truth) को बताते हैं; जैसे

a) If you freeze water, it becomes a solid.
b) If people eat too much, they get fat.
c) If water reaches 100 degrees, it always boils.
d) Plants die if they don’t get enough water.
e) If my son has a cold, I usually catch it.
f) If public transport is efficient, people stop using their cars.
g) People die if they don’t eat.
h) You get water if you mix hydrogen and oxygen.
i) Snakes bite if they are scared.
j) If babies are hungry, they cry

NOTE-I: Zero conditional sentences में ‘if’ के स्थान पर ‘when’ का use किया जा सकता है, ऐसा करने से sentence के अर्थ में कोई फर्क नहीं पड़ता; जैसे

If you heat ice, it melts.
= When you heat ice it melts.

NOTE-II: Zero conditional sentences को कोई निर्देश (instruction) देने के लिए भी use किया जाता है. ऐसे में sentence का main clause आज्ञासूचक (imperative) होता है; जैसे

a) If Rohit phones, tell him to meet me at the restaurant.
b) If you want to come, call me before 5:00.
c) Meet me here if we get separated.

‘Zero Conditionals’ और ‘Type-I Conditionals’ में अंतर

Type-I Conditional Sentences में main clause में वर्णित स्थिति काल्पनिक होती है; इसका पूरा होना ‘if-clause’ में वर्णित शर्त के पूरा होने पर निर्भर होता है. परंतु Zero Conditional Sentences में कोई कल्पना नहीं होती; परिणाम होता ही होता है. ये समझने के लिए निम्नलिखित वाक्य पढ़िए:

1. If Ruchi runs fast she’ll reach the station in time.

[यह एक Type-I Conditional Sentence है. क्योंकि इसके main clause में वर्णित स्थिति ‘रूचि का station पर समय पर पहुंचना’ इस बात पर निर्भर करेगा  कि वह तेज दोड़े, फिर भी पता नहीं वह पहंच पायेगी भी या नहीं; अर्थात स्थिति काल्पनिक है.]

2. If you freeze water, it becomes a solid.

[यह एक Zero Conditional Sentence है क्योंकि इसके main clause में वर्णित स्थिति ‘पानी का ठोस होने में बदलना’ एक सामान्य सच्च (general truth) है; अगर पानी को जमाया जायेगा तो वो ठोस पदार्थ में बदलेगा ही बदलेगा.]

NOTE: Type-I Conditional Sentences में ‘if’ को ‘when’ से नहीं बदला जा सकता; जबकि Zero Conditional Sentences में ‘if’ और ‘when’ दोनों को एक-दूसरे के साथ बदला जा सकता है.

ZERO CONDITIONALS SENTENCES (EXPLAINED IN ENGLISH)

In zero conditional sentences, the tense in both parts of the sentence is the Present Simple Tense. These conditionals sentences are used when the result will always happen. They often refer to general truths, such as scientific facts; e.g.

a) If you freeze water, it becomes a solid.
b) If people eat too much, they get fat.
c) If water reaches 100 degrees, it always boils.
d) Plants die if they don’t get enough water.
e) If my son has a cold, I usually catch it.
f) If public transport is efficient, people stop using their cars.
g) People die if they don’t eat.
h) You get water if you mix hydrogen and oxygen.
i) Snakes bite if they are scared.
j) If babies are hungry, they cry

NOTE-I: In zero conditional sentences, you can replace ‘if’ with ‘when’ because both express general truths. The meaning will be unchanged; e.g.

If you heat ice, it melts.
= When you heat ice it melts.

NOTE-II: The zero conditional is also often used to give instructions, using the imperative in the main clause; e.g.

a) If Rohit phones, tell him to meet me at the restaurant.
b) If you want to come, call me before 5:00.
c) Meet me here if we get separated.

Difference between ‘Zero Conditionals’ and ‘Type-I Conditionals’

In Type-I Conditional Sentences, the situation described in the main clause is imaginary, and that imaginary situation is quite likely to happen if the condition described in the ‘if-clause’ is fulfilled. But in the zero conditional sentences there is no imagination at all, if the condition described in the ‘if-clause’ is fulfilled, the result will always happen. Now compare these sentences.

1. If she runs she’ll reach the station in time.

[This is a type-I conditional sentence, not the zero conditional as the situation of the main clause i.e. ‘reaching the station in time’ might not always happen, sometimes it’s also possible even if she runs she is late to reach the station.]

2. If you freeze water, it becomes a solid.

[This is a zero conditional sentence, not the type-I conditional as the situation of the main clause i.e. ‘change of water into solid’ is a fact and will always happen if someone freezes it. There is no element of imagination (unreality) involved in it.]

NOTE: You can’t replace ‘if’ of type-I conditional sentences with ‘when’, whereas in zero conditional sentences ‘if’ and ‘when’ are replaceable.
