WEBVTT 00:00.180 --> 00:02.550 Welcome to this tutorial. 00:02.550 --> 00:06.570 Today we're going to talk about conditionals the zero type. 00:07.440 --> 00:08.400 Let's get started 00:11.430 --> 00:18.080 now conditionals are sentences with two clauses a main clause and and if clause. 00:18.270 --> 00:25.080 Now conditionals state that the action in the main clause can only take place if a certain condition 00:25.500 --> 00:28.670 in the if clause is fulfilled. 00:28.680 --> 00:31.830 Have a look at the example over here. 00:31.830 --> 00:35.720 If we don't hurry we'll be late. 00:35.730 --> 00:42.990 Now this is a conditional sentence and it's used to seed that the mean action in the main clause. 00:42.990 --> 00:49.860 Being late will take place if we do not hurry. 00:50.030 --> 00:54.710 Now there are five main types of conditionals in English. 00:55.070 --> 00:58.190 And amongst them are zero conditionals. 00:58.310 --> 01:04.460 Now zero conditionals aren't used to describe things that are always or generally true. 01:04.500 --> 01:12.490 Thus we refer to the real impossible situations general truths or scientific facts. 01:12.560 --> 01:15.670 Have a look at the example below. 01:15.740 --> 01:20.510 If two people fall in love they become a couple. 01:20.510 --> 01:29.840 Now in general people become a couple if they fall in love with each other now make sure to use the 01:29.840 --> 01:34.490 present simple tense in both parts of the zero conditionals. 01:34.490 --> 01:42.830 Note that the order of the mean and if clause is not fixed although when the if clause precedes the 01:42.830 --> 01:46.080 mean one make sure to use a coma. 01:46.100 --> 01:55.340 Have a look at the table below the if clause includes if clause present simple in a main clause present 01:55.340 --> 01:56.490 simple. 01:56.580 --> 01:59.630 Have a look at the examples below. 01:59.690 --> 02:10.030 If the temperature is above zero degrees outside the snow melts general truth if my friend invites me 02:10.090 --> 02:10.900 over. 02:11.020 --> 02:14.110 I always accept her invitation. 02:14.110 --> 02:16.590 General choose. 02:16.720 --> 02:22.930 Note that we can use when instead of if without any changes in the meaning. 02:23.030 --> 02:33.660 Thus in the example below when winter comes the birds fly to the south now zero conditionals are often 02:33.660 --> 02:35.730 used to give instructions. 02:35.730 --> 02:42.660 In this case we use the imperative in the main clause as in the examples below. 02:42.660 --> 02:45.090 Call me if you need any help. 02:46.350 --> 02:50.160 If you are not satisfied with your major changes.
