Now let's review and practice a bit.
Remember that zero conditionals are used to describe things that are always or generally true.
Thus we refer to the real and possible situations general truths or scientific facts.
Now read the sentences below and mark the main clause as M in the if clause as if people close their
eyes when they get scared.
Main clause if clause pupils can be expelled if they don't respect school rules
main clause if clause if you want to buy something sweet go to the supermarket.
If clause mean clause
also remember that we use the present simple tense in both parts of the zero conditionals.
Now create a sentence using the words in the bracket when people do throw away plastic bottles.
We pollute our planet
when people throw away plastic bottles.
We pollute our planet.
Is it to be late not to go home alone
if it is late.
Don't go home alone.
