  Conditional sentences (if-clauses, main clauses) * The conditional sentences are sometimes confusing for learners of English. Watch out: 1) Which type of the conditional sentences is used? 2) Where is the if-clause (e.g. at the beginning or at the end of the conditional sentence)? There are three types of the if-clauses. 1- The Zero Conditional: (if + present simple, ... present simple) * When we talk about things that are generally or always true, we can use: - If/When/Unless plus a present form PLUS present simple or imperative.examples: - If he gets there before me, ask him to wait. - When you fly budget airline, you have to pay for your drinks and snacks. - Unless you need more space, a small car is big enough for one person. * Notice that 'unless' means the same as 'if not'. * We can make a zero conditional sentence with two present simple verbs (one in the 'if clause' and one in the 'main clause'): If + present si...

The Four Smart Students

Par -

One night four college students were out partying late night and didn’t study for the test which was scheduled for the next day. In the morning, they thought of a plan. They made themselves look dirty with grease and dirt. Then they went to the Dean and said they had gone out to a wedding last night and on their way back the tire of their car burst and they had to push the car all the way back. So they were in no condition to take the test. The Dean thought for a minute and said they can have the re-test after 3 days. They thanked him and said they will be ready by that time. On the third day, they appeared before the Dean. The Dean said that as this was a Special Condition Test, all four were required to sit in separate classrooms for the test. They all agreed as they had prepared well in the last 3 days. The Test consisted of only 2 questions with the total of 100 Points:              ...

Past Continuous

PAST PROGRESSIVE TENSE ----> What is the past progressive tense? The past progressive tense describes an action in progress around a specific time in the past. Here are two examples: Q: What were you doing at 10:00 this morning? A: I was getting ready for school (at 10:00 this morning). Q: What were you doing when I called you? A: I was walking the dog (when you called me). Note that in all the sentences, a particular time is referenced. In the first example, both the question and the answer mention 10:00 am. In the second example, when you called me refers to a specific time which both speakers understand. (Perhaps, for example, the phone call was placed on a Saturday afternoon around 3:00. Both speakers know this, so the time is specific.) It's also important to note that we don't use the past progressive tense for repeated actions in the past. The simple past tense is used for any repeated actions that happened in the past. ----> W...
