Tenses Test 3

All crises (plural of crisis) are "fearful" and "damaging". So (2) and (3) do not add anything to the sentence. (I) and (4) does not make any sense.

Option A) more is litter is incorrect grammatically.

Option B is correct: Hurry up! The programme is about to start. 

Option A is correct: Unless we start now we can't be on time. 

Sentence A points out at action action that just happened. The explanation 'Look!' expresses the tone of surprise at the action, indicating that the action of 'coffee being spilled' just happened.

The given sentence is a first conditional; this means that the main clause "How can Rambha attend the wedding" with the modal 'can' expresses a future possibility. In this case, the tense of the if-clause (if she _____?) must be in the simple present tense.
Structure of first conditional:
Main clause (simple future/ possibility, permission, advice) + if clause (simple present tense)
Option C: 'Is not invited' is in the simple present tense. Hence this is the correct option.
Options A and D: 'Did not invite' is in the past tense. Also, it is in the active voice. So, the sentence sounds incomplete (if she did not invite whom?)
Similarly, 'has not invited' is also in the passive voice, whereas the if-clause is in passive voice.
Option B: 'Was not invited' is in the past tense, it refers to a past action, but cannot be applied here, as the sentence expresses a future possibility.
Hence options A, B and D are incorrect.

Note: In active voice, the subject performs an action.
In passive voice, the subject receives an action.

NOTE: As the action of 'planning' ended when 'my little sister told me', we will use the past perfect continuous tense, to explain that the action was continuing in the past before another action took place.

NOTE: As the duration of the first action is given, before the other action took place, we will use the past perfect continuous tense.

The type 3 conditional is used to refer to a time that is in the past, and a situation that is contrary to reality. The facts they are based on are the opposite of what is expressed. The type 3 conditional is used to refer to an unreal past condition and its probable past result. In type 3 conditional sentences, the if clause uses the past perfect (if I had known his address), and the main clause uses the perfect conditional (I would have gone to see him). Hence, Option C is correct. The rest of the options do not express this conditional, hence they're incorrect.
