00:00.180 --> 00:03.930
Now let's review and practice a bit.

00:04.020 --> 00:11.120
Remember that zero conditionals are used to describe things that are always or generally true.

00:11.120 --> 00:19.670
Thus we refer to the real and possible situations general truths or scientific facts.

00:19.710 --> 00:29.620
Now read the sentences below and mark the main clause as M in the if clause as if people close their

00:29.740 --> 00:32.260
eyes when they get scared.

00:38.490 --> 00:48.040

00:51.330 --> 00:59.880

01:03.660 --> 01:06.300
If clause mean clause

01:09.910 --> 01:16.780
also remember that we use the present simple tense in both parts of the zero conditionals.

01:16.780 --> 01:25.600
Now create a sentence using the words in the bracket when people do throw away plastic bottles.

01:25.600 --> 01:27.910

01:31.380 --> 01:34.440
when people throw away plastic bottles.

01:34.500 --> 01:38.210
We pollute our planet.

01:38.350 --> 01:42.540
Is it to be late not to go home alone

01:47.190 --> 01:48.660
if it is late.

01:48.750 --> 01:49.860
